Introduction The aim of this study was to determine the degree and nature of bacterial contamination of computer equipment in three Korean emergency departments (ED). Methods Hand hygiene practices of ED doctors and nurses were observed before contact with computer equipment. Microbiological swab samples were obtained from 112 multiple-user computer keyboards and electronic mice in the ED of three teaching hospitals. Isolated organisms were identified by a clinical microbiologist using Gram stain, colony morphology, and susceptibility test. Results Of the 112 samples, 103 (92.0%) showed growth of organisms on culture. Thirty-eight (33.9%) pieces of computer equipment yielded multiple bacterial species. Coagulase-negative Staphylococcus was the most common microorganism isolated (85.7%). Methicillin-resistant Staphylococcus aureus was obtained from two keyboards in two hospitals (1.8%). Hand hygiene compliance was observed on 29.9% occasions. Hand hygiene compliance after patient contact (38.0%) was higher than after other environmental contact (20.7%). Conclusions Multiple user computer equipment in the ED may serve as reservoirs for nosocomial infection. Hand hygiene should be performed before and after using all ED equipment, including computer equipment.

Full textAbstract:
Transmission of COVID-19 occurs between humans through droplets or splashes of body fluids containing SARS-CoV-2 particles. If a COVID-19 patient does not cover his mouth and nose when coughing or sneezing, the patient will emit droplets containing the virus. Droplets can stick to the patient's hands and surrounding items. Anyone can get the virus when shaking hands or touching items that have the virus and contracting the virus if they touch their eyes, nose, or mouth without washing their hands first. In public places such as schools, offices, and hospitals, many pieces of equipment are controlled using the help/touch of a hand. The use of equipment in public places by many vulnerable people is the cause of the rapid spread of infectious diseases. The research that will be carried out is to design and manufacture tools to control equipment without touching hands to prevent the spread of infectious diseases. The controlled equipment consists of water faucets, lights, fans, and curtains. The lights, fans, and water faucets are controlled using palm movements with the max distance from the Smart IR Switch being 11 cm. If there is palm movement within the working range of the Smart Switch IR, the solenoid valve, lights and fans will change from their previous conditions. If the initial condition is 'off' it will change to 'on' or vice versa. The curtain is controlled using palm movements with the max distance to the GP2Y0A21YK0F IR sensor being 10 cm. If there is palm movement within the working range of the GP2Y0A21YK0F IR sensor then the curtain will change from its previous condition. If the initial condition of the closed curtain changes to open or vice versa.

Full textAbstract:
Initiatives related to reverse logistics are increasingly common in companies that produce tires, lubricating oils, batteries, and electronic equipment, among others. In the pharmaceutical sector, reverse logistics is also relevant, contributing to reduce medication exposure to other people and the environment. Thus, this research seeks to find out which practices related to reverse logistics are used in 13 hospitals in the state of Rio de Janeiro. Regarding the methodological procedures, this research is supported by interviews with those responsible for disposing of medicines from hospitals, and the best practices were ranked using the analytic hierarchy process (AHP) method. Among the main difficulties for performing Medicine Reverse Logistics practices in hospitals, the absence of a standard process for medicine disposal and medications held by nurses or satellite pharmacies—for being out of control—stand out.

Full textAbstract:
Due to the limited resources of specialized hospital departments, the allocation of patients to different hospitals according to the severity of their condition is an extraordinarily complex and time-critical problem. The emergency capacity was determined for all medical centers (n = 135) in the State of Hessen, for patients of the various hospitalization triage categories (red, yellow, green), for normal working hours, for weekends and nights, including logistic specifications of a potential helicopter landing. This data was entered into a state register. Using the data from the “acute-care-register”, a Ticket System was developed that allows the operations management to assign patients according to the severity of their condition, urgency and necessary specialization (e.g., neurosurgery, ophthalmology, pediatrics) to a hospital without exceeding the admission and/or treatment capacity of the hospital/facility. During a non-critical period, the order of allocations depending on the distance of the clinic to the site of the emergency is planned in advance so that no further modifications are necessary during the acute intervention phase of an emergency response. Additional notification of hospital capacities for severe casualties provided during the emergency response can be easily and immediately supplemented. Due to the relatively low frequency of such emergency responses, a cost-effective concept that is easily adaptable to the respective fields of application has been discovered. The system is a sticker set customized for the respective rescue teams. The sets will be carried permanently in the rescue equipment by the organization manager of the rescue service team. The equipment is not dependent on electronic components. The cost per sticker set is approximately US$50. Keeping track of the patient allocations is assured.

Full textAbstract:
Background: Little information has been documented regarding interventions for mastitis by Australian physiotherapists. It is currently not known if physiotherapy interventions vary across Australian regions and types of healthcare facilities. Research aims: (1) To identify the interventions used by Australian physiotherapists treating mothers with mastitis and (2) to determine the variability in interventions used across regions and facilities. Methods: A retrospective observational design was used. A sample of case records of mothers with mastitis was identified ( N = 192). These case records documented physiotherapy interventions for mastitis in hospitals and private physiotherapy practices in Western Australia ( n = 77; 40.1%), Victoria ( n = 76; 39.6%), and New South Wales ( n = 39; 20.3%). An electronic data collection tool was designed to examine intervention variables. Results: The physiotherapy interventions received by mothers included therapeutic ultrasound (n=175; 91.1%), education and advice ( n = 160; 83.3%), and massage ( n = 103; 53.6%). Therapeutic ultrasound parameters varied across regions and types of healthcare facilities. Mean documented therapeutic ultrasound intensity was approximately twice as high in New South Wales and Victoria than in Western Australia. Conclusions: Regional and facility differences exist in physiotherapy interventions for mastitis in Australia. Healthcare professionals who refer to physiotherapists for mastitis should be aware that interventions received may differ across regions and facility types.

Introduction The use of motorized scooters is gaining popularity in Canada and elsewhere. This study aims to summarize characteristics of injuries related to use of motorized scooters using data from the electronic Canadian Hospitals Injury Reporting and Prevention Program (eCHIRPP) and to analyze trends. The eCHIRPP collects information associated with the injury event and clinical information related to treatment (the injured body part, the nature of the injury, injury intent and treatment received) from 11 pediatric and 9 general hospitals across Canada. Results A freetext search using keywords identified 523 cases related to motorized scooter injuries between January 2012 and December 2019. Most of the injuries reported were among males (62.7%). Fracture/dislocation was the most frequent injury (36.9%),and 14.3% of all patients were admitted to hospital. Joinpoint regression showed a statistically significant increase in injuries related to motorized scooter use between 2012 and 2017 (annual percent change of 18.4%). Conclusion Study findings indicate the need for continued preventive efforts and improved educational messages on safe riding and the importance of the use of protective equipment to prevent injuries among riders.

Full textAbstract:
With characters of low cost, portability, easy disposal, and high accuracy, as well as bulky reduced laboratory equipment, paper-based sensors are getting increasing attention for reliable indoor/outdoor onsite detection with nonexpert operation. They have become powerful analysis tools in trace detection with ultra-low detection limits and extremely high accuracy, resulting in their great popularity in medical detection, environmental inspection, and other applications. Herein, we summarize and generalize the recently reported paper-based sensors based on their application for mechanics, biomolecules, food safety, and environmental inspection. Based on the biological, physical, and chemical analytes-sensitive electrical or optical signals, extensive detections of a large number of factors such as humidity, pressure, nucleic acid, protein, sugar, biomarkers, metal ions, and organic/inorganic chemical substances have been reported via paper-based sensors. Challenges faced by the current paper-based sensors from the fundamental problems and practical applications are subsequently analyzed; thus, the future directions of paper-based sensors are specified for their rapid handheld testing.

Full textAbstract:
Objective The aim of the present study was to audit the current use of medical records to determine completeness and concordance with other sources of medical information. Methods Medical records for 40 patients from each of five Melbourne major metropolitan hospitals were randomly selected (n=200). A quantitative audit was performed for detailed patient information and medical record keeping, as well as data collection, storage and utilisation. Using each hospital’s current online clinical database, scanned files and paperwork available for each patient audited, the reviewers sourced as much relevant information as possible within a 30-min time allocation from both the record and the discharge summary. Results Of all medical records audited, 82% contained medical and surgical history, allergy information and patient demographics. All audited discharge summaries lacked at least one of the following: demographics, medication allergies, medical and surgical history, medications and adverse drug event information. Only 49% of records audited showed evidence the discharge summary was sent outside the institution. Conclusions The quality of medical data captured and information management is variable across hospitals. It is recommended that medical history documentation guidelines and standardised discharge summaries be implemented in Australian healthcare services. What is known about this topic? Australia has a complex health system, the government has approved funding to develop a universal online electronic medical record system and is currently trialling this in an opt-out style in the Napean Blue Mountains (NSW) and in Northern Queensland. The system was originally named the personally controlled electronic health record but has since been changed to MyHealth Record (2016). In Victoria, there exists a wide range of electronic health records used to varying degrees, with some hospitals still relying on paper-based records and many using scanned medical records. This causes inefficiencies in the recall of patient information and can potentially lead to incidences of adverse drug events. What does this paper add? This paper supports the concept of a shared medical record system using 200 audited patient records across five Victorian metropolitan hospitals, comparing the current information systems in place for healthcare practitioners to retrieve data. This research identifies the degree of concordance between these sources of information and in doing so, areas for improvement. What are the implications for practitioners? Implications of this research are the improvements in the quality, storage and accessibility of medical data in Australian healthcare systems. This is a relevant issue in the current Australian environment where no guidelines exist across the board in medical history documentation or in the distribution of discharge summaries to other healthcare providers (general practitioners, etc).

Full textAbstract:
The unrestrained monitor reduces monitoring load, but the variety of physiological values is limited. We propose a new method for measuring oxygen desaturation frequency by analyzing Cheyne-Stokes-like breathing curves based on the fact that the characteristic pattern of the curve occurs at a high probability at oxygen desaturation. We confirmed the effectiveness of our proposal in experiments on patients with sleep apnea and other disorders. This proposal is applicable to any sensors that monitor breathing curves and in calculating physiological values using unrestrained monitors at home and in screenings examination at hospitals having no special equipment.

In light of the COVID-19 pandemic, the Medicines and Healthcare products Regulatory Agency administered the standards for producing a Rapidly Manufactured Ventilator System (RMVS) free of charge due to the United Kingdom’s shortfall of ventilator systems throughout health centers. The standards delineate the minimum requirements in which a Rapidly Manufactured Ventilator System must encompass to be admissible for usage within hospitals. This work commences by evaluating the standards provided by the government to identify any potential security vulnerabilities that may arise due to the succinct development standards provided by the MHRA. This research investigates what cyber considerations are taken to safeguard a patient’s health and medical data to improve situational awareness. A tool for a remotely accessible, low-cost ventilator system is developed to reveal what a malicious actor may be able to inflict on a modern ventilator and its adverse impact.

Full textAbstract:
Elective surgery waiting list management is a major public healthcare issue. This case study describes an integrated multifaceted approach to waiting list management at Peninsula Health, a public health service in Victoria, Australia. At the commencement of this study it was recognised that several issues associated with the urological surgical service constituted potential clinical risk. These included: recall mechanisms for multiple surveillance procedures; significant resource deficits; and long surgery waiting times. Responding to these issues a multifaceted approach to wait list management was implemented including: audit; direct lines of communication between clinical and administrative staff; urgent caseload management; utilisation of the Elective Surgery Access Scheme; financial and resource analysis justifying the appointment of a full-time urologist, and the establishment of a urology service from a satellite campus; implementation of a recall database; development of an outpatient service; and commencement of a day surgery initiative. This approach yielded results that included a 67% reduction in the number of ‘ready for care’ patients and a 78% reduction in the number of patients classified as ‘overdue for surgery’. Average wait time for semi-urgent and non-urgent patients reduced from 248 days to 180 days in the 10-month period. What is known about the topic? Currently there are ~3000 people on the elective surgery waiting list in Victoria. Reasons for delays are multifactorial including shortage of beds, lack of surgeons, theatres and equipment. Patients are placed on the surgery waiting list according to a clinical urgency category assigned by their specialist. These categories are used by the hospitals to ensure that the patients with the greatest need are treated in the shortest period of time. Despite this, the numbers on the elective waiting lists within certain surgical specialities continue to grow and the numbers seen within the recommended time decreases. What does this paper add? This paper outlines a management strategy for the urology wait list at a large Victorian hospital. It outlines six approaches, the implementation of which had a measurable positive effect on the waiting list numbers. What are the implications for practitioners? The strategies put into place have been sustainable and continue to ensure that the urology waiting list is well managed.

AbstractBackground:SARS-CoV-2 has been implicated in the largest recorded coronavirus outbreak to date. Initially, most COVID-19 cases were in China, but the virus has spread to more than 184 countries worldwide, and the United States currently has more cases than any other country.Objective:With person-to-person spread expanding in the United States, we describe hospital preparedness for managing suspected and confirmed COVID-19 patients.Design:Cross-sectional survey focused on various elements of respiratory disease preparedness.Setting:Critical access hospitals (CAHs) and acute-care hospitals (ACHs) in Idaho.Methods:The electronic survey was sent to infection preventionists (IPs) and nurse administrators in 44 hospitals in Idaho.Results:Overall, 32 (73%) hospitals responded to the survey. Participating facilities reported their preparedness with respect to existing, formalized structures for managing infectious disease incidents—specifically COVID-19—as well as availability of resources, such as isolation rooms and personal protective equipment, for safely managing suspected and confirmed COVID-19 cases.Conclusions:Hospitals covered by the survey had varying levels of preparedness for managing COVID-19 cases, with differences across the various categories of interest in this study. Although the study reveals strengths, including in application of emergency management and infection control frameworks, it also suggests that other areas, such as consistent implementation of federal guidelines and requirements for infection prevention, are potential areas for strengthening preparedness for SARS-CoV-2 and other respiratory pathogens with pandemic potential.

AbstractObjectiveThe 2014 Ebola virus disease (EVD) outbreak in West Africa remains the most deadly in history. Emergency departments (EDs) are more likely to come into contact with potential EVD patients. It is important for EDs to be prepared to care for suspected EVD patients. Our objective was to understand the perceived challenges experienced by Washington State ED medical directors in EVD preparedness.MethodsAn anonymous, electronic survey was sent to a convenience sample of ED medical directors across Washington State between November and February of 2014–2015. The perceived challenges of and attitudes toward EVD preparations were assessed and reported as stratified proportions.ResultsOf 85 medical directors contacted, 59 responses (69%) were received. This included EDs with annual patient volumes of <20,000 (20 hospitals, 34%), 20,000 to 40,000 (21 hospitals, 36%), 41,000 to 60,000 (4 hospitals, 6.8%), and >60,000 (12 hospitals, 20%). Among the perceived challenges in EVD preparations were spatial modifications (eg, building an anteroom for donning and doffing of personal protective equipment) and waste management planning. Ninety-five percent of respondents moderately or strongly agreed that it is important to have a predesignated hospital to care for EVD patients.ConclusionsWashington State ED medical directors have faced significant challenges in ensuring their EDs are prepared to safely care for suspected EVD patients. Attitudes toward EVD preparations are mixed. Varying levels of perceived importance may represent an additional barrier to statewide EVD preparedness.

Full textAbstract:
There is an increasing need to diagnose Parkinson’s disease (PD) in an early stage. Existing solutions mainly focused on traditional ways such as MRI, thus suffering from the ease-of-use issue. This work presents a new approach using video and skeleton-based techniques to solve this problem. In this paper, an end-to-end Parkinson’s disease early diagnosis method based on graph convolution networks is proposed, which takes patients’ skeletons sequence as input and returns the diagnosis result. The asymmetric dual-branch network architecture is designed to process global and local information separately and capture the subtle manifestation of PD. To train the network, we present the first Parkinson’s disease gait dataset, PD-Walk. This dataset consists of 95 PD patients and 96 healthy people’s walking videos. All the data are annotated by experienced doctors. Furthermore, we implement our method on portable equipment, which has been in operation in the First Affiliated Hospital, Zhejiang University School of Medicine. Experiments show that our method can achieve 84.1% accuracy and achieve real-time performance on the equipment in the real environment. Compared with traditional solutions, the proposed method can detect suspicious PD symptoms quickly and conveniently. Integrated equipment can be easily placed in hospitals or nursing homes to provide services for elderly people.

With the continuous deepening of Chinese medical and health system reform, hospital informatization construction is advancing by leaps and bounds, especially in the context of “Internet of Things + Medical,” hospital informatization construction has made significant progress. However, computer network security management and maintenance work still face many contradictions and problems, and we need to pay attention to them. Based on the analysis of the current situation of computer network security management and maintenance in hospital information construction, this paper focuses on the problems of computer network security management and maintenance and proposes targeted optimization countermeasures. Based on the current problems faced by the medical industry in our country and the state’s support for the medical Internet of Things, this paper studies the application of the Internet of Things in hospital information management at home and abroad. This article uses hospital information network security maintenance evaluation methods and evaluation indicators to conduct an empirical analysis of the information security maintenance level of these 12 hospitals, from the risk assessment of hospital information network security, the establishment of strategies, the level of information security software and hardware equipment, and the information security personnel. Experiments show that 58.33% of the hospitals surveyed have only done part of the work on risk analysis and risk assessment of their own network information security, and 41.67% of the hospitals have not done this work at all. This shows that hospitals should incorporate computer network security management and maintenance into the information construction system, focusing on the outstanding problems and possible risks faced by the arm’s computer network security management and maintenance, and vigorously promote the reform and innovation of computer network security management and maintenance.

Abstract With the increasing need for and use of electrical energy amid increasingly rapid technological advances, especially in the use of electronic equipment in hospitals, it is necessary to pay attention to the problem of harmonics due to the use of non-linear electrical equipment. Therefore, it is necessary to measure the current and voltage THD for each non-linear equipment user. If the current and voltage THD values do not meet the standards, then a filter design is carried out so that the THD values meet the standards. Based on the results of THD measurements on the Main Distribution Panel (MDP) of RSU UKI, it was found that the THD of the voltage varied between 0.7877% - 2.4363% and the current THD varied between 5.3073% - 9.2363%. The measured THD value refers to the IEEE 519-2014 standard. If the THD value of the measurement results exceeds the IEEE 519-2014 standard, a harmonic filter is needed. With the simulated single tuned filter design, the current THD decreases within the standard value. The THD value of the current after installing the filter at the three MDP’s of the RSU UKI, namely MDP A of 1.72%, MDP B of 0.64% and MDP C of 1.30%.

INTRODUCTION:The hospital's design today must be prepared for changes resulting from the incorporation of new information and communication technologies (ICT) (1). These will affect non-finalistic (warehouse, archive), diagnostic support (laboratory and image) and finalistic activities (emergency, surgical center, clinics) (2). The Health Technology Assessment (HTA) is fundamental in the dimension of the impact of each technology on the structure of healthcare facilities (HCF). In this way, this work intends to evaluate the trends of impact of the new ICT on hospitals’ structure.METHODS:The main technologies under discussion in Management of HCF in Brazillian Health Regulatory Agency were raised. From this survey an impact matrix was built with hospital environmental design and the trends of adequacy of its space.RESULTS:ICT that tend to decrease the physical space are: electronic health record for the archive, use of digital imaging for radiology, Radio-Frequency Identification (RFID) for the warehouse, point of care and automated laboratory equipment for clinical laboratories.ICT that tend to increase physical space are: Telemedicine for the surgical center, Internet of Things - IoT for Intensive Care Units, beds for emergency and hospitalization.The technologies that present an undefined tendency in relation to physical space are: automatic dispensers of drugs for nursing posts.The use of database servers and the need for network points are still undefined due to the use of Wi-Fi technology and cloud storage. However, it's possible to increase use of electricity and the internet.CONCLUSIONS:It is concluded that the new ICT will have an impact on the planning and building of the future HCF (3). The designs of today's buildings should consider this trend so that the future reality is adequate and the regulatory requirements about HCF should be able to consider it.

Continuous progressive wheel resulted in scattered plans of the major objective to climb the ladder of success within a very short period of time. Within past years, Electronic Health Records (EHR) have been realized due to the growing number of hospitals worldwide. EHR systems can be in different forms, that refer to a wide range of electronic information systems used in healthcare. Medical institutions that might use EHRs are hospitals, pharmacies, general surgery practices, and other health care professionals. Clinical or medical coding is an important process to transform medical documents such as laboratory or radiologic results beside physician notes into universal alphanumeric codes that represents the medical diagnosis, procedure, service, or equipment. As archiving process is an important part of the clinical lab, besides searching for related information or previous tests’ results are boring work and in order to make this process easier, faster and accurate, this paper proposed the design and implementation of a web-based clinical laboratory management system, in which only authorized systems’ users such as lab assistant or physician can access patients’ records in order to ensure that the whole process is secure, accurate and reliable. This system is developed using MySQL for database design and PHP, html, CSS and JavaScript for user interfaces.

The stethoscope is a piece of medical standard equipment that isused by a physician for an initial examination of the patient. Generally, the stethoscopeis used for auscultating sounds which are generated by the workings of organ systems such as cardiac, lung or digestive. In the present condition with the growing number of the patient population, it has an impact on the burden of hospitals and medical practitioners. So that treatment is not optimal, especially patients who need continuous monitoring. Thus it needs a system that can work dynamically, flexibly and remotely based. This paper focuses on the implementation of the electronic stethoscope which is integrated with a mobile phone as the modality of online data transmission through the internet network. The prototype of an electronic stethoscope uses condenser mic, pre-amplifier, wide bandpass filter (20 Hz-1 KHz) and audio amplifier. The maximum gain is 28.63 dB in the 20 Hz-690 Hz frequency range. The signal output can be connected to the android mobile through the jacked phone to be stored in MP3 format and then sent to the cloud server for further monitoring and analysis. The application called “Steder” supports realtime communication between patient and physician for medical check-up, consultation, and discussion activities.

Abstract Background Early assessments of COVID19 preparedness reported resource shortages, use of crisis capacity strategies, variations in testing, personal protective equipment (PPE), and policies in US hospitals. One year later, we performed a follow-up survey to assess changes in infection prevention practice and policies in our diverse network of community and academic hospitals. Methods This was a cross-sectional electronic survey of infection preventionists in 58 hospitals within the Duke Infection Control Outreach Network (community) and Duke/UNC Health systems (academic) in April-May 2021 to follow-up our initial survey from April 2020. The follow-up survey included 26 questions related to resource availability, crisis capacity strategies, procedures, changes to PPE and testing, and staffing challenges. Results We received 54 responses (response rate, 93%). Facilities reported significantly fewer PPE and resource shortages in the follow-up survey compared to our initial survey (Figure 1, P< 0.05). Only 32% of respondents were still reprocessing N95 respirators (compared to 73% in initial survey, P< 0.05). All hospitals performed universal masking, universal symptom screening on entry, and 30% required eye protection. In 2020, most hospitals suspended elective surgical procedures in March-April, and restarted in May-June. Approximately 92% reported in-house testing for SARS-COV-2 by April 2020, at least a third of which had a weekly capacity of >100 tests. Almost 80% performed universal pre-operative testing, while 61% performed universal preadmission testing for SARS-COV-2. Almost all hospitals switched from test-based to time-based strategy for discontinuing isolation precautions, majority in August-September 2020. Twenty-five percent hospitals reported infection prevention furloughs, staffing cuts, and or reassignments, while 81% reported increased use of agency nursing during the pandemic. Conclusion Our follow-up survey reveals improvement in resource availability, evolution of PPE guidance, increase in testing capacity, and burdensome staffing changes. Our serial surveys suggest increasing uniformity in infection prevention policies, but also highlight the increase in staff turnover and infection prevention staffing shortages. Disclosures Sonali D.

<b><i>Background:</i></b> We aimed to evaluate the policies and practices about neonatal resuscitation in a large sample of European hospitals. <b><i>Methods:</i></b> This was a cross-sectional electronic survey. A 91-item questionnaire focusing on the current delivery room practices in neonatal resuscitation domains was individually sent to the directors of 730 European neonatal facilities or (in 5 countries) made available as a Web-based link. A comparison was made between hospitals with ≤2,000 and those with >2,000 births/year and between hospitals in 5 European areas (Eastern Europe, Italy, Mediterranean countries, Turkey, and Western Europe). <b><i>Results:</i></b> The response rate was 57% and included participants from 33 European countries. In 2018, approximately 1.27 million births occurred at the participating hospitals, with a median of 1,900 births/center (interquartile range: 1,400–3,000). Routine antenatal counseling (<i>p</i> < 0.05), the presence of a resuscitation team at all deliveries (<i>p</i> < 0.01), umbilical cord management (<i>p</i> < 0.01), practices for thermal management (<i>p</i> < 0.05), and heart rate monitoring (<i>p</i> < 0.01) were significantly different between hospitals with ≤2,000 births/year and those with >2,000 births/year. Ethical and educational aspects were similar between hospitals with low and high birth volumes. Significant variance in practice, ethical decision-making, and training programs were found between hospitals in 5 different European areas. <b><i>Conclusions:</i></b> Several recommendations about available equipment and clinical practices recommended by the international guidelines are already implemented by centers in Europe, but a large variance still persists. Clinicians and stakeholders should consider this information when allocating resources and planning European perinatal programs.

Full textAbstract:
Power quality is a pressing concern and of the utmost importance for advanced and high-tech equipment in particular, whose performance relies heavily on the supply’s quality. Power quality issues like voltage sags/swells, harmonics, interruptions, etc. are defined as any deviations in current, voltage, or frequency that result in end-use equipment damage or failure. Sensitive loads like medical equipment in hospitals and health clinics, schools, prisons, etc. malfunction for the outages and interruptions, thereby causing substantial economic losses. For enhancing power quality, custom power devices (CPDs) are recommended, among which the Dynamic Voltage Restorer (DVR) is considered as the best and cost-effective solution. DVR is a power electronic-based solution to mitigate and compensate voltage sags. This paper provides a thorough discussion and comprehensive review of DVR topologies based on operations, power converters, control methods, and applications. The review compares the state-of-the-art in works of literature, and comparative study on power quality issues, the DVR principle along with its operation modes, the DVR components, the DVR topologies based on energy storage, the DVR topologies based on single-/three-phase power converters, and the DVR topologies based on control units that have different control processing stages. Furthermore, modified and improved configurations of the DVR, as well as its integration with distributed generations, are described. This work serves as a comprehensive and useful reference for those who have an interest in researching DVRs.

It is mandatory that healthcare workers wear personal protective equipment (PPE) while caring for COVID-19 patients. Studies have shown that wearing PPE for a prolonged time may lead to symptoms of physical discomfort including headache. The aim of this study is to assess the prevalence and association between prolonged use of PPE and headaches. This was a cross-sectional study. A convenience sample of healthcare workers who worked with COVID-19 patients in clinical settings was recruited. The data were collected through an electronic survey shared as a link through social media. This study included 1060 participants, 753 (71%) female and 307 (29%) male. Participants were divided into two groups. Group A had 628 (60%) participants who did not have chronic headache before the COVID-19 pandemic, while Group B contained 432 (40%) participants who had a previous chronic headache. Headaches differed significantly between Groups A and B in frequency, type, location, and quality during the COVID-19 period. The analysis found a significant relationship between duration of PPE use and headache occurrence. The significant relationship between the duration of PPE usage and headache occurrence among healthcare workers should be considered when refining policies and procedures regarding prolonged PPE use.

Full textAbstract:
With the popularity of the internet 5G network, the network constructions of hospitals have also rapidly developed. Operations management in the healthcare system is becoming paperless, for example, via a shared electronic medical record (EMR) system. A shared electronic medical record system plays an important role in reducing diagnosis costs and improving diagnostic accuracy. In the traditional electronic medical record system, centralized database storage is typically used. Once there is a problem with the data storage, it could cause data privacy disclosure and security risks. Blockchain is tamper-proof and data traceable. It can ensure the security and correctness of data. Proxy re-encryption technology can ensure the safe sharing and transmission of relatively sensitive data. Based on the above situation, we propose an electronic medical record system based on consortium blockchain and proxy re-encryption to solve the problem of EMR security sharing. Electronic equipment in this process is connected to the blockchain network, and the security of data access is ensured through the automatic execution of blockchain chaincodes; the attribute-based access control method ensures fine-grained access to the data and improves the system security. Compared with the existing electronic medical records based on cloud storage, the system not only realizes the sharing of electronic medical records, but it also has advantages in privacy protection, access control, data security, etc.

Background & Objective: Novel Coronavirus-2019, the cause of COVID-19, was first discovered at the end of 2019 in Wuhan City. Analysis of confirmed cases in China states that 7%-26% of patients with severe disease required intensive care. The high number of cases of COVID-19 forced the ‘North Sumatra Indonesian Society of Anesthesiology & Intensive Therapy (NSISAIT) COVID-19 Task Force’ to manage and monitor appropriate intensive therapy at selected referral hospitals.
We conducted this study to know the comfort level of the NSISAIT COVID-19 Task Force during the management of intensive therapy at the COVID-19 referral hospitals.
Methodology: This study used a descriptive observational method with a cross sectional design. A questionnaire was designed and circulated by electronic means among the physicians involved in management of COVID-19 patients as a part of NSISAIT COVID-19 Task Force. The responses received were grouped and categorized using MS Excel software.
Results: The results of the study showed that the comfort level of the NSISAIT COVID-19 Task Force was categorized as satisfactory by almost half of the respondents. The COVID-19 handling was categorized as very good by 34 (65.4%) respondents; 25 (48.1%) felt a fairly good level of security, 21 (40.4%) answered that the facilities and infrastructure at the referral hospitals were quite good, 28 (53.8%) respondents received a very good award; and 27 respondents (51.9%) carried out intensive therapy management quite well.
Conclusion: The comfort level of the NSISAIT COVID-19 Task Force in the management of intensive therapy at the COVID-19 referral hospitals was in the comfortable category.

Summary Aim: The working group on positron emission tomography (PET) of the DGN (German Society of Nuclear Medicine) initiated this first survey to collect and analyse information on the practise of PET in Germany in the year 2008. Methods: A questionnaire was sent to PET performing facilities (medical practices, hospitals, university hospitals and others) for retrospective data acquisition. Details regarding the equipment and examination procedures were examined as well as indications and number of studies. In addition, the role of PET within the diagnostic process was evaluated. Results: Responses from 65 sites were analysed. Their technical equipment consisted of 77 PET scanners (40 of them were combined PET/CT devices). About 63 500 PET studies had been performed with 86% in the field of oncology, 8% in neurology and 3% in cardiology. The radiotracers were labelled with 18F in 91% of the studies, whereas 68Ga was used in 4% and 11C in 3%. The analyses revealed lung tumours as the most investigated tumour entity, followed by malignant lymphoma, tumours of the gastro-intestinal tract and prostate cancer (about 14 000, 6000, 5000 and 2000). Corresponding to the new scanners and software procedures, the number of studies with attenuation correction by CT was high (68%) and nearly all studies were reconstructed iteratively (99%). The PET images were analysed quantitatively in the majority of cases (91%). The clinical reports, which included image documentation for the greater part, were posted regularly within 3 days. However, in 70% of the sites electronic transfer possibilities were used additionally to speed up the diagnostic process. The high standard of quality was demonstrated by the fact, that 40 facilities were engaged in a tumour board. Further on, one third of the physicians had gained a PET certification awarded by the DGN. Conclusion: Relative to the high general standard of diagnostic instrumentation in Germany, PET is less established, in particular when compared with other industrialised countries such as USA and Switzerland.

Abstract In view of the current panorama of hospital nutritional care, it is necessary to review nutritional care practices in hospital units, in order to ensure nutritional monitoring and quality of care. Therefore, it is necessary to build flows of nutritional assistance practices at the pediatric hospital level, based on the recommendations of the Federal Council of Nutritionists and the Brazilian Society of Parenteral and Enteral Nutrition, aiming at not generating a deficit in the nutritional monitoring of the patient and in reducing the risk of contamination of the professional. When individual protection equipment is available, nutritional admission will be made in person and during hospitalization, monitoring can be performed using secondary data from electronic medical records and / or telecommunication with the multidisciplinary team. The implementation of nutritional routines in hospitals in times of Covid-19 pandemic generates more assertive conducts for the prevention and treatment of malnutrition and other nutritional implications, also guaranteeing the safety of professionals in assistance in pediatric units..

Full textAbstract:
Nosocomial infection is one of the most important problems that occurs in hospitals, as it directly affects susceptible patients or patients with immune deficiency. Klebsiella pneumoniae (K. pneumoniae) is the most common cause of nosocomial infections in hospitals. K. pneumoniae can cause various diseases such as pneumonia, urinary tract infections, septicemias, and soft tissue infections, and it has also become highly resistant to antibiotics. The principal routes for the transmission of K. pneumoniae are via the gastrointestinal tract and the hands of hospital personnel via healthcare workers, patients, hospital equipment, and interventional procedures. These bacteria can spread rapidly in the hospital environment and tend to cause nosocomial outbreaks. In this research, we developed a MIP-based electrochemical biosensor to detect K. pneumoniae. Quantitative detection was performed using an electrochemical technique to measure the changes in electrical signals in different concentrations of K. pneumoniae ranging from 10 to 105 CFU/mL. Our MIP-based K. pneumoniae sensor was found to achieve a high linear response, with an R2 value of 0.9919. A sensitivity test was also performed on bacteria with a similar structure to that of K. pneumoniae. The sensitivity results show that the MIP-based K. pneumoniae biosensor with a gold electrode was the most sensitive, with a 7.51 (% relative current/log concentration) when compared with the MIP sensor applied with Pseudomonas aeruginosa and Enterococcus faecalis, where the sensitivity was 2.634 and 2.226, respectively. Our sensor was also able to achieve a limit of detection (LOD) of 0.012 CFU/mL and limit of quantitation (LOQ) of 1.61 CFU/mL.

Full textAbstract:
COVID-19 infections can spread silently, due to the simultaneous presence of significant numbers of both critical and asymptomatic to mild cases. While, for the former reliable data are available (in the form of number of hospitalization and/or beds in intensive care units), this is not the case of the latter. Hence, analytical tools designed to generate reliable forecast and future scenarios, should be implemented to help decision-makers to plan ahead (e.g., medical structures and equipment). Previous work of one of the authors shows that an alternative formulation of the Test Positivity Rate (TPR), i.e., the proportion of the number of persons tested positive in a given day, exhibits a strong correlation with the number of patients admitted in hospitals and intensive care units. In this paper, we investigate the lagged correlation structure between the newly defined TPR and the hospitalized people time series, exploiting a rigorous statistical model, the Seasonal Auto Regressive Moving Average (SARIMA). The rigorous analytical framework chosen, i.e., the stochastic processes theory, allowed for a reliable forecasting about 12 days ahead of those quantities. The proposed approach would also allow decision-makers to forecast the number of beds in hospitals and intensive care units needed 12 days ahead. The obtained results show that a standardized TPR index is a valuable metric to monitor the growth of the COVID-19 epidemic. The index can be computed on daily basis and it is probably one of the best forecasting tools available today for predicting hospital and intensive care units overload, being an optimal compromise between simplicity of calculation and accuracy.

Background/aimsTo report refractive outcomes from an National Health Service (NHS) cataract surgery service and assess if results meet suggested benchmark standard.MethodsDetails of all patients undergoing cataract surgery in the Southern General and New Victoria hospitals in Glasgow, UK, between November 2006 and December 2016 were prospectively entered into an electronic database. Patients were reviewed 4 weeks postoperatively in the eye clinic and underwent refraction at their local optometrist prior to this appointment. Surgically uncomplicated cases with in the bag’ non-toric intraocular lens implantation were included. Patients with previous laser refractive procedures or failing to achieve 6/12 acuity or better postoperatively were excluded. Proximity to targeted postoperative refraction was documented.ResultsOver this 10-year period, 11 083 eyes underwent cataract surgery. Of these, 8943 eyes of 6936 patients (80.69%) met the inclusion criteria and had both target and postoperative outcome refraction recorded. The mean difference between the targeted and outcome refraction was −0.07 D (SD 0.67). The mean absolute error was 0.50 D. Postoperative refraction was within 1 D of target refraction for 7938 eyes (88.76%) and within 0.50 D for 5577 eyes (62.36%).ConclusionRefractive outcomes following routine cataract surgery reported here are well within the targets recommended by the Royal College of Ophthalmologists and European guidelines, but suggest that higher cataract refractive outcome benchmark standards may not yet be a realistic expectation for all NHS units with current biometry practice.

BACKGROUND: Coronavirus disease (COVID)-19 emerges worldwide consideration since their first proving. The knowledge and attitude of all medical personnel play an important role in the effectiveness of infection control policies among medical institutions.
AIM: The study evaluates the knowledge of health care workers (HCWs) about infection control policies at the Egyptian institutions trying to identify the degree of their awareness to deal with such outbreak.
METHODS: A cross-sectional study was implemented in public and private hospitals sectors at Cairo, Egypt, through a structured self-administered questionnaire that was delivered to HCWs in the selected hospitals.
RESULTS: A total of 486 physicians working between university, governmental, teaching, private hospitals, and polyclinics submitted their replies. Of whom, 46.9% practiced internal medicine specialty, 35.4% were pediatricians, and only 17.7% specialized in the family medicine. Regarding the overall level of knowledge about infection control and prevention among HCWs, we found that 87.2% of participants reported presence of infection control program at their institutions and about 79% practiced these policies while only 60.5% received some training. Furthermore, we found that 64.2% of the participant did not know which infections are officially reported. There was some variation in response to causes related to the outbreak as 43.8% referred that to shortage of appropriate personnel protective equipment and only 7.4% assigned the carelessness of HCWs. Moreover, the insufficient resources to fulfill the infection control requirements were assigned as a primary factor to spread of infection (71.4%). The electronic surveillance system was believed the most efficient reporting system of infectious agents by staff (83.1%). The study revealed that there was a statistically significant difference of knowledge of infection control among medical staff according to their specialties (p ≤ 0.05). Moreover, there was a significant trend of orientation about infection control toward the highly certificated individuals (having PhD). Furthermore, there was a potential variance between the groups of higher and lower years of experience regarding in their answers about surveillance system institutions (p ≤ 0.05). In addition, there was variation in responses to questions related to various institutions as a higher percent of awareness of the presence of active infection control policy was found at the governmental and university hospitals (p < 0.05).
CONCLUSION: HCWs had reasonable knowledge about infection control and surveillance during COVID-19 outbreak and we have discovered zones of concern about infection control experience in Egypt which differ between institutions and professions and years of experience.

Full textAbstract:
Pulse oximetry enables oxygen saturation estimation ( S p O 2) non-invasively in real time with few components and modest processing power. With the advent of affordable development kits dedicated to the monitoring of biosignals, capabilities once reserved to hospitals and high-end research laboratories are becoming accessible for rapid prototyping. While one may think that medical-grade equipment differs greatly in quality, surprisingly, we found that the performance requirements are not widely different from available consumer-grade components, especially regarding the photodetection module in pulse oximetry. This study investigates how the use of candidate light sources and photodetectors for the development of a custom S p O 2 monitoring system can lead to inaccuracies when using the standard computational model for oxygen saturation without calibration. Following the optical characterization of selected light sources, we compare the extracted parameters to the key features in their respective datasheet. We then quantify the wavelength shift caused by spectral pairing of light sources in association with photodetectors. Finally, using the widely used approximation, we report the resulting absolute error in S p O 2 estimation and show that it can lead up to 8% of the critical 90–100% saturation window.

Hospitals, especially their emergency services, receive a high number of wrist fracture cases. For correct diagnosis and proper treatment of these, images obtained from various medical equipment must be viewed by physicians, along with the patient’s medical records and physical examination. The aim of this study is to perform fracture detection by use of deep-learning on wrist X-ray images to support physicians in the diagnosis of these fractures, particularly in the emergency services. Using SABL, RegNet, RetinaNet, PAA, Libra R-CNN, FSAF, Faster R-CNN, Dynamic R-CNN and DCN deep-learning-based object detection models with various backbones, 20 different fracture detection procedures were performed on Gazi University Hospital’s dataset of wrist X-ray images. To further improve these procedures, five different ensemble models were developed and then used to reform an ensemble model to develop a unique detection model, ‘wrist fracture detection-combo (WFD-C)’. From 26 different models for fracture detection, the highest detection result obtained was 0.8639 average precision (AP50) in the WFD-C model. Huawei Turkey R&D Center supports this study within the scope of the ongoing cooperation project coded 071813 between Gazi University, Huawei and Medskor.

Abstract: The bone is a major component of the human body. Bone provides the ability to move the body. The bone fractures are common in the human body. The doctors use the X-ray image to diagnose the fractured bone. Therefore, an automated system needs to develop to diagnose the fractured bone The Deep Neural Network (DNN) is widely used for the modelling of the power electronic devices. This study showed that a deep learning model can be trained to detect fractures in radiographs with diagnostic accuracy similar to that of senior subspecialized orthopaedic surgeons. The aim of this study is to perform fracture detection by use of deep-learning on X-ray images to support physicians in the diagnosis of these fractures, particularly in the emergency Services. Hospitals, especially their emergency services, receive a high number of fracture cases. For correct diagnosis and proper treatment of these, images obtained from various medical equipment must be viewed by physicians, along with the patient’s medical records and physical examination. Recent advancement in image processing and deep learning create some hopes in devising more enhanced applications. Therefore, data augmentation techniques have been used to increase the size of the data set

Full textAbstract:
The widespread use of cell phones has led to cell phone towers being located in many communities. These towers, also called base stations, incorporate electronic equipment and antennas that receive and transmit radiofrequency signals. Along with the towers, used for TV and line of sight microwave communication, the proliferation of these base stations is having a detrimental effect on urban esthetics. It is highly recommended for developing urban areas to consider the problem of these unsightly towers as a form of visual pollution, which increases in parallel with the rise of human population density, and also, the possible electromagnetic field (EMF) hazard due to the existence of the cell phone towers in the residential areas. This paper presents the feasibility of using camouflaged cell phone towers to improve the quality of the urban environment. Cell phone towers disguised as trees might address the visual pollution, while, at the same time, might also mitigate the possible EMF hazard by installing these disguised towers in free spaces, rather than on the roof of buildings, schools, hospitals, etc. The feasibility of implementing such a scenario for a quality urban environment in Koya city is discussed.

Full textAbstract:
Medical imaging is considered one of the most important advances in the history of medicine and has become an essential part of the diagnosis and treatment of patients. Earlier prediction and treatment have been driving the acquisition of higher image resolutions as well as the fusion of different modalities, raising the need for sophisticated hardware and software systems for medical image registration, storage, analysis, and processing. In this scenario and given the new clinical pipelines and the huge clinical burden of hospitals, these systems are often required to provide both highly accurate and real-time processing of large amounts of imaging data. Additionally, lowering the prices of each part of imaging equipment, as well as its development and implementation, and increasing their lifespan is crucial to minimize the cost and lead to more accessible healthcare. This paper focuses on the evolution and the application of different hardware architectures (namely, CPU, GPU, DSP, FPGA, and ASIC) in medical imaging through various specific examples and discussing different options depending on the specific application. The main purpose is to provide a general introduction to hardware acceleration techniques for medical imaging researchers and developers who need to accelerate their implementations.

Full textAbstract:
The electrocardiogram (ECG) is basic equipment used in the diagnosis of cardiac illness. However, in non-developed countries, most of the population does not have access to medical tests, and many hospitals do not even have these ECGs. On the other hand, the electrical signals generated by the heart and acquired by the ECG have low power and are affected by electromagnetic interference (EMI), mainly produced by the electrical system. Filtering EMI when frequency varies is a challenging task. Within this context, this work aims to produce an easy-to-use low-cost ECG with good electromagnetic disturbances rejection. The proposed noise rejection system is composed of two moving average filters and a phase-locked-loop, namely 2MAV-PLL. The system operates with a low sampling frequency and attenuates the EMI noise present in the ECG signal regardless of the amplitude, obtaining a filtered signal with a 44-dB signal–noise ratio (SNR) between the frequencies of± 10 Hz of the fundamental frequency. Simulation and experimental results prove that the ECG system can attenuate the EMI using relatively low sampling frequency, giving adequate information for health professionals to properly evaluate an electrocardiogram.

Excessive work for clinicians
Too many unnecessary reports and requirements
Over-dependence on technology
Conflict between the need for professional autonomy and establishing the dynamically changing best processes
Care delivery “silos” resulting from lack of interdepartmental teamwork
Constant distractions and interruptions
Too many policies and procedures, leading to a tendency to follow marginally effective methods
Over-reliance on electronic medical tracking taking precedence over bedside discussions with patients
Inattention to detail
Lack of motivation to get, or resources for, a second opinion
Quick diagnosis based on past observations
Inadequate attention to medical equipment dangers
Insufficient effort in infection prevention
People pretending the negative would not happen to them
Hospitals looking for quick profit
Questionable alternate boards certifying physicians who may not be qualified
A lack of passion for work
Unfavorable workflows, such as labs located far from the emergency department
A lack of clarity of what is required to assure patient safety
Too much team consensus instead of challenging the quality of intervention

Full textAbstract:
Acoustical privacy and noise control design and implementation guidance is needed, regarding Facility Guidelines Institute (FGI) criteria for outpatient medical facilty tenant improvements (TI). TI in existing commercial buildings or medical office buildings may not have capital budgets or expected facility/lease life that hospitals enjoy. Full conformance to FGI criteria and guidelines may be limited; by economic feasibility and by constructability. Design professionals can use "good practice" space planning, demising assembly selection, and electronic sound masking to achieve appropriate acoustical privacy within reasonable capital expense budgets. Consider FGI criteria for demising partition, ceiling, door and window selections plus infrastructure equipment and material selections that can provide cost-effective lightweight, common construction standards. The objectives are to protect the privacy of patient information and provide quiet spaces, free of transient disturbance for clear speech communications. Continuous ambient sound increases speech privacy including speech transmitted from enclosed quiet spaces. Criteria for acoustics, speech privacy,continuous noise and masking exists in FGI. Temporal level changes (on/off, transients) and tonality (spectrum smoothness or balance) should be considered in basis-of-design (BoD). This paper will present design guidelines for selecting demising assemblies and supplemental sound masking for outpatient clinical spaces in commercial or medical office buildings.

Full textAbstract:
After the first wave of COVID-19, the Spanish Society of Thoracic Surgeons (SECT) surveyed its members to assess the impact of the pandemic on thoracic oncology surgery in Spain. In May 2020, all SECT members were invited to complete an online, 40-item, multiple choice questionnaire. The questionnaire was developed by the SECT Scientific Committee and sent via email. The overall response rate was 19.2%. The respondents answered at least 91.5% of the items, with only one exception (a question about residents). Most respondents (89.3%) worked in public hospitals. The reported impact of the pandemic on routine clinical activity was considered extreme or severe by 75.5% of respondents (25.5% and 50%, respectively). Multidisciplinary tumour boards were held either with fewer members attending or through electronic platforms (44.6% and 35.9%, respectively). Surgical activity decreased by 95.7%, with 41.5% of centers performing surgery only on oncological patients and 11.7% only in emergencies. Nearly 60% of respondents reported modifying standard protocols for early-stage cancer and in the preoperative workup. Most centers (≈80%) reported using full personal protective equipment when operating on COVID-19 positive patients. The COVID-19 pandemic severely affected thoracic oncology surgery in Spain. The lack of common protocols led to a variable care delivery to lung cancer patients.

Full textAbstract:
Background: Digitization of healthcare data has led to widespread healthcare transformation. This has been enhanced by the availability of new technologies at lower costs. Video recording can improve the quality of care, provider skills, education, and patient follow-up. However, limitations such as the risk of litigation, patient privacy, and poor legal framework have curtailed adoption. Rural hospitals have older analog equipment due to limited financial resources. Objectives: This study aims to present an alternative low-cost option. Methods: We present an economical method of recording and digitizing endoscopic and laparoscopic procedures performed on analog video processing towers. We showcase a video of the step-by-step procedure that involves connecting a digital video home system (VHS) video recorder to an analog Olympus endoscopy machine (Model CV-100) and transferring media via a portable storage device to an electronic medical record database. Conclusion: Using simple home video recording devices provides a low-cost solution to creating digital records from analog video endoscopic machines. The technique, however, creates additional steps to the endoscopy process and the need for capacity building of the endoscopist. Patient consent forms should cover video creation. Medical centers should have a robust information management system to securely store and retrieve digitized video records.

Full textAbstract:
Background The use of mobile devices in hospital care constantly increases. However, smartphones and tablets have not yet widely become official working equipment in medical care. Meanwhile, the parallel use of private and official devices in hospitals is common. Medical staff use smartphones and tablets in a growing number of ways. This mixture of devices and how they can be used is a challenge to persons in charge of defining strategies and rules for the usage of mobile devices in hospital care. Objective Therefore, we aimed to examine the status quo of physicians’ mobile device usage and concrete requirements and their future expectations of how mobile devices can be used. Methods We performed a web-based survey among physicians in 8 German university hospitals from June to October 2019. The online survey was forwarded by hospital management personnel to physicians from all departments involved in patient care at the local sites. Results A total of 303 physicians from almost all medical fields and work experience levels completed the web-based survey. The majority regarded a tablet (211/303, 69.6%) and a smartphone (177/303, 58.4%) as the ideal devices for their operational area. In practice, physicians are still predominantly using desktop computers during their worktime (mean percentage of worktime spent on a desktop computer: 56.8%; smartphone: 12.8%; tablet: 3.6%). Today, physicians use mobile devices for basic tasks such as oral (171/303, 56.4%) and written (118/303, 38.9%) communication and to look up dosages, diagnoses, and guidelines (194/303, 64.0%). Respondents are also willing to use mobile devices for more advanced applications such as an early warning system (224/303, 73.9%) and mobile electronic health records (211/303, 69.6%). We found a significant association between the technical affinity and the preference of device in medical care (χs2=53.84, P<.001) showing that with increasing self-reported technical affinity, the preference for smartphones and tablets increases compared to desktop computers. Conclusions Physicians in German university hospitals have a high technical affinity and positive attitude toward the widespread implementation of mobile devices in clinical care. They are willing to use official mobile devices in clinical practice for basic and advanced mobile health uses. Thus, the reason for the low usage is not a lack of willingness of the potential users. Challenges that hinder the wider adoption of mobile devices might be regulatory, financial and organizational issues, and missing interoperability standards of clinical information systems, but also a shortage of areas of application in which workflows are adapted for (small) mobile devices.

Abstract Background Critical Access Hospitals (CAH) may face challenges with limited resources in their infection prevention and control (IPC) program. As part of the Project Firstline collaborative, the University of Nebraska Medical Center and its clinical partner Nebraska Medicine sought to identify needs and develop resources to mitigate IPC program gaps in small and rural hospitals, including CAHs. Since, little is known about the resources needed by CAHs to strengthen their IPC program, a needs assessment survey was deployed to Federal Emergency Management Agency Region VII CAHs. Methods A 49-question Research Electronic Data Capture (REDCap) survey was distributed via email to infection preventionists in Region VII CAHs. The survey had 4 sections with questions focused on IPC program infrastructure, competency-based training, audit and feedback, and identification and isolation of high-risk pathogens/serious communicable diseases. An IPC practice score was assigned to each CAH by totaling “yes” responses. A “no” or “not sure” response was considered an IPC gap. Respondents who selected “no” were asked to identify resources that would assist in mitigating identified gaps. Descriptive analyses evaluated frequency of gaps and most cited resources. Welch t-test was used to study differences in IPC practice score between states. Results 50 CAHs (33 in NE, 16 in IA and 1 in KS) and 1 small NE hospital (not licensed as CAH but included in the analyses as CAH) participated in the survey. Majority (n=38) responded to all sections with IPC scores ranging from 13 to 48. There was no significant difference between IPC practice scores of CAHs in NE and IA (average score 33 vs 36; p = 0.38). Specific IPC practice gaps present in > 50% of CAHs were related to audit and feedback practices (Table 1). Additional gaps included lack of drug diversion program, absence of input from IPC team prior to purchasing equipment and failure to conduct risk assessment for the laboratory. Most CAHs cited a standardized audit tool and staff training materials as much needed resources (Table 1). Table 1. Needs/Resources for the identified Infection Prevention and Control Gaps. Conclusion Major IPC gaps exist in CAHs with many of them related to implementing audit and feedback practices that are an essential component of a successful IPC program. Focus should be directed on developing resources to mitigate identified IPC gaps. Disclosures M. Salman Ashraf, MBBS, Merck & Co.
