Full textAbstract:
This paper evaluates the performance of the Hospital Morbidity Data System, maintained by the Health Statistics Branch (HSB) of the Health Department of Western Australia (WA). The time taken to process discharge summaries was compared in the first and second halves of 1995, using the number of weeks taken to process 90% of all discharges and the percentage of records processed within four weeks as indicators of throughput. Both the hospitals and the HSB showed improvements in timeliness during the second half of the year. The paper also examines the impact of a recently introduced electronic data transfer system for WA country public hospitals on the timeliness of morbidity data. The processing time of country hospital records by the HSB was reduced to a similar time as for metropolitan hospitals, but the processing time in the hospitals increased, resulting in little improvement in total processing time.

Full textAbstract:
A study of the preferred thinking styles among senior health professionals is reported. A total of 49 medical consultants, 50 senior nurses and 53 health managers from two public teaching hospitals in Adelaide, Australia, were invited via a personal letter to complete a questionnaire comprising measures of thinking style (the Rational Experiential Inventory) and cognitive style (two dimensions of the Myers–Briggs Type Indicator®). Managers reported a higher preference for ‘rational’ reasoning than nurses, whereas medical consultants reported a lower preference for ‘experiential’ reasoning than both managers and nurses. Cognitive style was largely homogenous. Although generalisation of the findings may be limited due to small sample sizes and the self-selection of participants, an understanding of the thinking styles of senior health professionals will likely inform the design and evaluation of future change strategies. What is known about the topic?Research outcomes cannot change population health unless they are adopted, but changing the practices of healthcare workers to reduce ‘know–do’ gaps is not simple. Although there is some evidence to support professionally-oriented strategies such as educational outreach, audit and feedback and reminders, success is sometimes limited, potentially reflecting the limited use of theory in informing the choice of implementation strategies. Non-theoretical approaches may obscure the behavioural determinants of, and mechanisms for, change, making it impossible to generalise lessons learned form one situation to other contexts. What does this paper add?This paper highlights the growing recognition of the need for theory in this important field, and examines a psychological theory for its potential use. Findings provide useful preliminary descriptive data about thinking dispositions within and between three key groups of healthcare decision-makers: senior consultants, senior nurses and managers. It adds to a modest but accumulating research base that explores the tenets of a specified theory among healthcare professionals, reporting reliable differences between individuals in terms of cognitive processing (i.e. how they prefer to think). What are the implications for practitioners?Those faced with implementing change should consider theoretically-driven approaches in their selection of strategies. Based on the theory explored herein, two versions of a message, each targeting a different cognitive processing mode, should be more successful than one version only. This should be true for all three professional groups, and represents a testable strategy for future research.

Abstract Objective Accurate identification of self-harm presentations to Emergency Departments (ED) can lead to more timely mental health support, aid in understanding the burden of suicidal intent in a population, and support impact evaluation of public health initiatives related to suicide prevention. Given lack of manual self-harm reporting in ED, we aim to develop an automated system for the detection of self-harm presentations directly from ED triage notes. Materials and methods We frame this as supervised classification using natural language processing (NLP), utilizing a large data set of 477 627 free-text triage notes from ED presentations in 2012–2018 to The Royal Melbourne Hospital, Australia. The data were highly imbalanced, with only 1.4% of triage notes relating to self-harm. We explored various preprocessing techniques, including spelling correction, negation detection, bigram replacement, and clinical concept recognition, and several machine learning methods. Results Our results show that machine learning methods dramatically outperform keyword-based methods. We achieved the best results with a calibrated Gradient Boosting model, showing 90% Precision and 90% Recall (PR-AUC 0.87) on blind test data. Prospective validation of the model achieves similar results (88% Precision; 89% Recall). Discussion ED notes are noisy texts, and simple token-based models work best. Negation detection and concept recognition did not change the results while bigram replacement significantly impaired model performance. Conclusion This first NLP-based classifier for self-harm in ED notes has practical value for identifying patients who would benefit from mental health follow-up in ED, and for supporting surveillance of self-harm and suicide prevention efforts in the population.

Full textAbstract:
Objective This cross-sectional study investigates the home enteral nutrition (HEN) services of public principal referral hospitals in NSW, Australia, comparing their services to best practice guidelines for HEN. Methods HEN service processes were investigated using an online questionnaire and telephone interview with the dietitian primarily working with HEN at each hospital. Results Participating hospitals reported a total of approximately 3200 HEN patients, 76% required oral nutrition support. Only 69% of hospitals had a dietitian allocated to their HEN service and no hospitals had established multidisciplinary teams to manage HEN patients. Post-discharge follow-up, as recommended for tube fed and oral patients, was achieved by 8% and 15% of hospitals respectively. Forty-six per cent of dietitians were satisfied and 46% of dietitians were dissatisfied with current HEN services provided, and reported the following improvements were required: increased clinical resources allocated to HEN dietitian/coordinator; increased outpatient services (home visits, outpatient clinic, multidisciplinary clinic); and an efficient registration process and database. Conclusions HEN services among participating hospitals are inconsistent, demonstrating gaps in service provision. Baseline assessment scores varied, with an average of 61% of recommendations currently in use. Best practice guidelines are not firmly adhered to due to limited funding and allocated resources for HEN. What is known about the topic? HEN is recognised as a cost-effective and reliable way of treating patients requiring nutrition support post hospital discharge. There are best practice guidelines available to ensure quality care is provided to HEN patients in the community or home setting. As there is no national framework in place for HEN in Australia, currently total patient numbers are unknown and each state and territory provides different levels of service delivery and funding for HEN. It is unknown how guidelines in Australia have been implemented and practiced, as no studies were found that have audited HEN services in Australia. What does this paper add? From the participating hospitals we were able to obtain updated data on HEN patient numbers (~3200). This paper reports on baseline scores in meeting best practice HEN guidelines for tertiary referral hospitals in NSW, Australia and identifies gaps in service provision. It is essential to identify reasons that limit adherence to HEN guidelines, as consequences may include unnecessary re-admissions to emergency departments or hospitals, increasing healthcare costs. Our study found notable differences in service provision ranging from 29% to 86% of recommendations of HEN guidelines achieved, and identified a lack of multidisciplinary teams to manage HEN patients. What are the implications for practitioners? We found HEN services among principal referral hospitals are inconsistent and best practice guidelines are currently not adhered to. National guidelines together with local health policies assist in defining the required standard of care, enhance service delivery and promote clinical excellence. We found the NSW Health Agency for Clinical Innovation HEN Implementation Checklist to be a practical tool for obtaining baseline scores for adherence to best practice guidelines. Regulation of HEN will be positive for HEN users by ensuring a more equitable service is available by introducing consistent funding for HEN nationally. However, it is the responsibility of states and local health districts to implement guidelines, contributing to better health and quality of care provided to patients.

Abstract The Tropical Rainfall Measuring Mission (TRMM) Multi-satellite Precipitation Analysis (TMPA) near-real-time (RT) data are considered less accurate than the TMPA research quality (RP) data because of the simplified data processing algorithm and the lack of gauge adjustments. However, for near-real-time hydrological applications, such as drought nowcasting, the RT data must play a key role given latency considerations and consistency is essential with products like RP, which have a long-term climatology. The authors used a bivariate test to examine the consistency between the monthly RT and RP precipitation estimates for 12 yr (2000–12) and found that, for over 75% of land cells globally, RT and RP were statistically consistent at 0.05 significance level. The inconsistent grid cells are spatially clustered in western North America, northern South America, central Africa, and most of Australia. The authors also show that RT generally increases with time relative to RP in northern South America and western Australia, while in western North America and eastern Australia, RT decreases relative to RP. In other areas such as the eastern part of North America, Eurasia, and southern part of the South America, the RT data are statistically consistent with the RP data and are appropriate for global- or macroscale hydrological applications.

Full textAbstract:
Background: The aim of this presentation is to provide an update on the economic evaluation of the Australian SunSmart program as well as outline the cost of skin cancer treatment to the Victorian public hospital system. This follows the publication of two recently released published economic evaluations that discusses the potential effects of skin cancer prevention inventions. Aim: 1. To highlight the cost effectiveness of skin cancer prevention in Australia 2. To highlight the costs of skin cancer treatment in the Victorian public hospital system 3. To provide strong evidence to inform governments of the value of skin cancer prevention to reduce the costs of treatment in future years. Methods: Program cost was compared with cost savings to determine the investment return of the program. In a separate study, a prevalence-based cost approach was undertaken in public hospitals in Victoria. Costs were estimated for inpatient admissions, using state service statistics, and outpatient services based on attendance at three hospitals in 2012-13. Cost-effectiveness for prevention was estimated from 'observed vs expected' analysis, together with program expenditure data. Results: With additional $AUD 0.16 ($USD 0.12) per capita investment into skin cancer prevention across Australia from 2011 to 2030, an upgraded SunSmart Program would prevent 45,000 melanoma and 95,000 NMSC cases. Potential savings in future healthcare costs were estimated at $200 million, while productivity gains were significant. A future upgraded SunSmart Program was predicted to be cost-saving from the funder perspective, with an investment return of $3.20 for every additional dollar the Australian governments/funding bodies invested into the program. In relation to the costs to the Victorian public hospital system, total annual costs were $48 million to $56 million. Skin cancer treatment in public hospitals ($9.20∼$10.39 per head/year) was 30-times current public funding in skin cancer prevention ($0.37 per head/year). Conclusion: The study demonstrates the strong economic credentials of the SunSmart Program, with a strong economic rationale for increased investment. Increased funding for skin cancer prevention must be kept high on the public health agenda. This would also have the dual benefit of enabling hospitals to redirect resources to nonpreventable conditions.

Full textAbstract:
PURPOSE Serum protein electrophoresis (SPEP) is a clinical tool used to screen for monoclonal gammopathy, thus it is a critical tool in the evaluation of patients with multiple myeloma. However, SPEP laboratory results are usually returned as short text reports, which are not amenable to simple computerized processing for large-scale studies. We applied natural language processing (NLP) to detect monoclonal gammopathy in SPEP laboratory results and compared its performance at multiple hospitals using both a rules-based manual system and a machine-learning algorithm. METHODS We used the data from the VA Corporate Data Warehouse, which comprises data from 20 million unique individuals. SPEP reports were collected from July to December 2015 at 5 Veterans Affairs Medical Centers. Of these reports, we annotated the presence or absence of monoclonal gammopathy in 300 reports. We applied a machine learning–based NLP and a manual rules-based NLP to detect monoclonal gammopathy in SPEP reports at each of the hospitals, then applied the model from 1 hospital to each of the other hospitals. RESULTS The learning system achieved an area under the receiver operating characteristic curve of 0.997, and the rules-based system achieved an accuracy of 0.99. When a model trained on 1 hospital’s data was applied to a different hospital, however, accuracy varied greatly, and the learning-based models performed better than the rules-based model. CONCLUSION Binary classification of short clinical texts such as SPEP reports may be a particularly attractive target on which to train highly accurate NLP systems.

Full textAbstract:
Objectives District hospitals are important symbolic structures in rural and remote communities; however, little has been published on the role, function or models of care of district hospitals in rural and remote Australia. The aim of the present study was to identify models of care that incorporate district hospitals and have relevance to the Australian rural and remote context. Methods A systematic, rapid review was conducted of published peer-reviewed and grey literature using CINAHL, Medline, PsychInfo, APAIS-Health, ATSI health, Health Collection, Health & Society, Meditext, RURAL, PubMed and Google Scholar. Search terms included ‘rural’, ‘small general and district hospitals’, ‘rural health services organisation & administration’, ‘medically underserved area’, ‘specific conditions, interventions, monitoring and evaluation’, ‘regional, rural and remote communities’, ‘NSW’, ‘Australia’ and ‘other OECD countries’ between 2002 and 2013. Models of teaching and education, multipurpose services centres, recruitment and/or retention were excluded. Results The search yielded 1626 articles and reports. Following removal of duplicates, initial screening and full text screening, 24 data sources remained: 21 peer-reviewed publications and three from the grey literature. Identified models of care related specifically to maternal and child health, end-of-life care, cancer care services, Aboriginal health, mental health, surgery and emergency care. Conclusion District hospitals play an important role in the delivery of care, particularly at key times in a person’s life (birth, death, episodes of illness). They enable people to remain in or near their own community with support from a range of services. They also play an important role in the essential fabric of the community and the vertical integration of the health services. What is known about the topic? Little has been published on the function of small-to-medium district hospitals in rural and remote Australia, and almost nothing is known about models of care that are relevant to these settings. What does this paper add? District hospitals form an important part of vertically integrated models of care in Australia. Effective models of care aim to keep health services close to home. There is scope for networked models of care that keep health care within the community supported by hub-and-spoke models of service delivery. What are the implications for practitioners? This review found limited evidence on the skill mix required in district hospitals; however, the skill mix underpins the extent of service and speciality that can be provided locally, particularly with regard to the provision of surgery and emergency services. International evidence suggests that providing surgical services locally can help increase the sustainability of smaller hospitals because they typically provide high return, short episodes of care; however, this depends on the funding model being used. Similarly, the skill mix of staff required to sustain a functioning emergency department brings a skill base that supports a higher level of expertise across the hospital.

Full textAbstract:
Whilst technology use has always been a part of the practice of health care delivery, more recently, information technology has been applied to aspects of clinical work concerned with documentation. This thesis presents an analysis of the ways that two professional groups, one clinical and one ancillary, at a single hospital cooperatively engage in a work practice that has recently been computerised. It investigates the way that a clinical group???s approach to and actual use of the system creates problems for the ancillary group. It understands these problems to arise from the contrasting ways that the groups position their use of documentation technology in their local definitions of professional status. The data on which analysis of these practices is based includes 16 hours of video recordings of the work practices of the two groups as they engage with the technology in their local work settings as well as video recordings of a reflexive viewing session conducted with participants from the ancillary group. Also included in the analysis are observational field notes, interviews and documentary analysis. The analysis aimed to produce a set of themes grounded in the specifics of the data, and drew on TLSTranscription?? software for the management and classification of video data. This thesis seeks to contribute to three research fields: health informatics, sociology of professions and social science research methodology. In terms of health informatics, this thesis argues for the necessity for health care information technology design to understand and incorporate the work practices of all professional groups who will be involved in using the technology system or whose work will be affected by its introduction. In terms of the sociology of professions, this thesis finds doctors and scientists to belong to two distinct occupational communities that each utilise documentation technology to different extents in their displays of professional competence. Thirdly, in terms of social science research methodology, this thesis speculates about the possibility for viewing the engagement of the groups with the research process as indicative of their reactions to future sources of outside perturbance to their work.

This research investigated the potential benefits, risks and challenges, innovation properties and viability of cloud computing for records management on an Australian organisation within the mining software development sector. This research involved the use of a case study results analysis as well as a literature analysis. The literature analysis identified the ten potential benefits of cloud computing, as well as the ten risks and challenges associated with cloud computing. It further identified aspects, which needed to be addressed when adopting cloud computing in order to promote innovation within an organisation.
The case study analysis was compared against a literature review of ten potential benefits of cloud computing, as well as the ten risks and challenges associated with cloud computing. This was done in order to determine cloud computing’s viability for records management for Company X (The company in the case study). Cloud computing was found to be viable for Company X. However, there were certain aspects, which need to be discussed and clarified with the cloud service provider beforehand in order to mitigate possible risks and compliance issues. It is also recommended that a cloud service provider who complies with international standards, such as ISO 15489, be selected. The viability of cloud computing for organisations similar to Company X (mining software development) followed a related path. These organisations need to ensure that the service provider is compliant with laws in their local jurisdiction, such as Electronic Transactions Act 1999 (Australia, 2011:14-15), as well as laws where their data (in the cloud) may be hosted. The benefits, risks and challenges of records management and cloud computing are applicable to these similar organisations. However, mitigation of these risks needs to be discussed with a cloud service provider beforehand.
From an innovation perspective, cloud computing is able to promote innovation within an organisation, if certain antecedents are dealt with. Furthermore, if cloud computing is successfully adopted then it should promote innovation within organisations.Information Science

Concerning the expansion of the coronavirus in the world, the search for the development of solutions related to the control and mitigation of the pandemic situation became constant. The paper addresses an analysis of localities for the installation of field hospitals, highly requested as a point of treatment for COVID-19. In this scenario, a framework based on the P-median approach and mathematical programming is proposed, enabling an optimization model as an analysis format for the problematic situation. To support the implementation of the model, a computational tool for data processing was developed, integrating an optimization model to the geographical evaluation, exploring in the analysis numerical and graphical resources. As a validation of the study, a case study in the city of Rio de Janeiro – Brazil is presented, analyzing 162 neighborhoods and determining seven favorable localities for the installation of field hospitals.

The electronic storage of medical patient data is becoming a daily experience in most of the practices and hospitals worldwide. However, much of the available data is in free text form, a convenient way of expressing concepts and events but especially challenging if one wants to perform automatic searches, summarization, or statistical analyses. Information Extraction can relieve some of these problems by offering a semantically informed interpretation and abstraction of the texts. MedInX, the Medical Information eXtraction system presented in this chapter is designed to process textual clinical discharge records in order to perform automatic and accurate mapping of free text reports onto a structured representation. MedInX components are based on Natural Language Processing principles and provide several mechanisms to read, process, and utilize external resources, such as terminologies and ontologies. MedInX current practical applications include automatic code assignment and an audit system capable of systematically analyze the content and completeness of the clinical reports. Recent evaluation efforts on a set of authentic patient discharge letters indicate that the system performs with 95% precision and recall.

Full textAbstract:
Abstract Sand production prediction is essential from the early stages of field development planning for well completion design and later for production management. Unconsolidated and weakly consolidated sandstones are prone to fail at low flowing bottom hole pressures during hydrocarbon production. To predict the sand-free drawdown, a robust sand prediction model that integrates near-wellbore and in-situ stresses, rock mechanical properties, well trajectory, reservoir pressure, production and depletion trends is required. Sanding prediction models should be calibrated with field data such as production and well tests observation. In the absence of field data, numerical techniques can provide a reliable estimate on potential onset and severity of sanding at various reservoir pressures. In this study, analytical and finite-element numerical models are independently used to predict the onset of sanding and volume of produced sand from high rate has wells with weakly consolidated sandstone reservoirs in onshore, Western Australia. The analytical method uses a poro-elastic model and core-calibrated log-derived rock strength profiles with an empirical effective rock strength factor (ESF). In the study, the ESF was calibrated against documented field sanding observation from a well test extended flow period at the initial reservoir pressure under a low drawdown pressure. The numerical method uses a poro-elasto-plastic model defined from triaxial core tests. The rock failure criterion in the numerical method is based on a critical strain limit (CSL) corresponding to the failure of the inner wall of thick-walled cylinder core tests that can also satisfy the existing wells sanding observations. To verify the onset and severity of sanding predicted by the analytical model, numerical simulations for an identical sandstone interval are developed to investigate the corresponding CSL. This combined analytical and numerical modelling calibrated with field data provided high confidence in the sanding evaluation and their application for future well completion and sand management decisions. The analytical model was finally used for sanding assessment over field life pressure condition because of its processing simplicity, speed and flexibility in assessing various pressure and rock strength scenarios with sensitivity analysis over the whole production interval in compared with the numerical method which is more suitable for single-depth, single pressure condition and well and perforation trajectory modelling.

In 2018 26th International Conference on Nuclear Engineering. American Society of Mechanical Engineers, 2018. http://dx.doi.org/10.1115/icone26-82039.
Full textAbstract:
Since August 2015 a new classification of radioactive waste was issued by Italian Ministry of Economic Development, in order to adapt Italian historical classification to European standards. This new classification provides 6 categories, from exempt to high level waste, and it is based on the waste final destination: from free release to final disposal or interim storage (high level waste and intermediate level waste with α-content higher than 400 Bq/g) [1]. Nucleco is a State owned Company acting as Waste Management Organization for radioactive waste coming from hospitals, industries and research and development activities not related to electricity production by nuclear plants. Nucleco collects, safely manages and temporarily stores waste that will be sent to the National Repository (site definition phase is still ongoing), while for the Short Lived Radionuclides and Very Low Activity waste Nucleco performs all necessary operations to be compliant with the conditions of release prescribed by the Italian Control Authority. Short Lived Radionuclides are those whose half-life is shorter than 100 days or reach the condition of non-radiological relevance in 5 years: they are mainly produced by bio-medical applications of radioactive materials. Very Low Activity waste are characterized by activity concentrations lower than 100 Bq/g (of which less than 10 Bq/g of α-emitting radionuclides) and reach the condition of non-radiological relevance in 10 years: these waste usually came from research institutions and industrial activities. This work presents the authorized operating procedures, the radiological measurements criteria and the technical know-how put in place by Nucleco to fulfil the provisions of Italian regulations for unconditioned release of radioactive waste. A case study of ISO 20’ containers is discussed in the current paper. Main emphasis will be addressed to: • gathering of historical information about the state of the material to be released and definition of the reference radiological spectrum; • sampling procedures to ensure representativeness of the samples from homogeneous waste batch to be released and then subjected to radiological characterization; • characterization phase consisting of the integration of several state-of-art techniques aiming to collect the most complete set of radiological data; • data processing protocols needed for the calculation of the activity concentrations for each radionuclide of the reference spectrum (or other radionuclides eventually detected); • evaluation of the main sources of uncertainty affecting the results; • comparison of the activity concentration (including the uncertainty) of each radionuclide with the corresponding authorized concentration limits.

Full textAbstract:
Sonic data are now acquired in most wellbores for a variety of applications including seismic tie, porosity evaluation, lithology determination, fracture detection, gas detection, and geomechanics modeling. The industry is also more aware of the impacts of intrinsic (fractures, layering), extrinsic (stress), and borehole effects that may affect the basic measurements of compressional and shear slownesses. Any advanced interpretation of sonic data has historically been done days to weeks after the acquisition, and the value of the measurement can be diminished due to the time of delivery of the final product. An updated data-driven inversion algorithm applied while logging can provide robust shear and compressional slownesses with associated quality control indicators. The updated algorithm has fewer user parameters and is more reliable in layered, stressed, or damaged formations. Processing quality is determined using the coherency of the measured signal and an industry-standard rock physics model for theoretical validation. With the updated dipole shear inversion and more flexible dipole anisotropy frequency filters, the dipole shear anisotropy processing can deliver reliable results at the wellsite. A byproduct of the new dipole shear inversion algorithm is the environmental slowness that is used to optimally fit the dipole dispersion signal. The interpretation of the environmental slowness parameter can indicate the anisotropy mechanism in addition to zones of near-wellbore alteration to provide further insight immediately. The wellsite dipole shear inversion and anisotropy processing were run on a vertical well in eastern Australia, within a stacked tight gas sand reservoir that requires hydraulic fracturing. The main application of the sonic data was reliable slownesses as input to stress modeling for designing the stimulation, but the direction of the maximum horizontal stresses within the clastic gas-filled zones was also required. The dipole shear inversion results were able to handle various lithologies and hole conditions, as well as identify vertical transverse isotropy (VTI) anisotropic shale intervals between the horizontally stressed sand zones.

Full textAbstract:
Since 1980, the National Agency ONDRAF/NIRAS has been responsible by law for the safe management of all radioactive waste produced in Belgium, including decommissioning waste. In 1991, its responsibility was extended by Royal Decree of 16.10.91 to the field of decommissioning, its main specific assignments being: • The collection and evaluation of data (physical and radiological inventories) from nuclear plants; • The approval of decommissioning programmes, including decommissioning cost evaluations and mechanisms of funding. Already in the early 90s, ONDRAF/NIRAS started with the implementation of its own integrated data processing system, recording the physical and radiological inventories of nuclear plants and allowing the evaluation of the quantities of decommissioning materials and waste as well as of the decommissioning costs of the plants. In 1997, the law on the inventory of nuclear liabilities of 12.12.97 completed and enforced the decree of 1991, stating that the agency will: • Draw up a register specifying the location and condition of all nuclear facilities and all sites containing radioactive substances on Belgian territory; • Estimate the cost of decommissioning and cleaning up these facilities and sites; • Evaluate the availability of sufficient funds to carry out these future or ongoing operations; • Update the inventory every five years. As a result, during these last few years, ONDRAF/NIRAS had to deal with an increasing amount of decommissioning data (submission of inventories, new decommissioning plans and also a first batch of five-yearly revisions) concerning a larger diversity of facility types (enlargement of activities to “smaller” licensees, like universities, hospitals, etc). Simultaneously and consequently, ONDRAF/NIRAS faced the need to integrate a larger range of field-experienced decontamination and dismantling techniques, performed by different decommissioning companies, in order to obtain more refined and “pertinent” cost evaluations. For the same purposes, it appeared necessary to consider alternative waste processing possibilities, especially for very low-level waster arising from decommissioning activities. In 2000, ONDRAF/NIRAS started to upgrade its Decommissioning Management System (DMS) in order to enhance the quality of the database (integrity, intrinsic validity, extrinsic validity, completeness and accuracy) and simultaneously to develop the flexibility and the abilities of the evaluation functions. This paper presents and describes the latest version of the ONDRAF/NIRAS DMS (the data model, interface facilities, and the calculation and reporting possibilities) putting emphasis on experience gained and on some of the first lessons learned. The two first sections of this paper give an overview of the National Agency’s main missions and outline the information and data collection process in the framework of decommissioning and inventory. Indeed, the context in which the updated DMS was developed and the difficulties encountered during the data collection process should inform the reader about the way the upgrading of the data system has been thought out and the alternatives the National Agency had to deal with. In the third section, the main functionalities of the DMS modules are set out in concrete terms, the main modules being: • The “Inventories” module, recording their physical and radiological inventories for the sites that fall within the scope; • The “Techniques” module, integrating measurement, decontamination, dismantling and special recycling techniques, as well as their unit cost elements; • The “Waste” module, integrating standard and special waste categories, their packaging, transportation and processing possibilities, as well as their unit cost elements; • The “Nominal Forecast” module, linking an inventory to selected techniques and waste costs, associated with the “best estimate” reference calculation scenario; • The “Scenario” module, dealing with the storage and evaluation of alternative scenarios (pessimistic or optimistic ones, deferred dismantling, etc). The last section focuses on experience gained through developing the upgraded DMS and putting it into operation. Some potentialities of the upgraded DMS are also discussed.
