Full textBackground: Data from the World Health Organization indicates poisoning as a major public health problem worldwide, especially in underdeveloped or developing countries. Objective: to estimate the mortality rate and to describe deaths from exogenous poisoning (EP) in São Paulo city in the year 2014. Methods: Data from the death records (basic cause) were collected in the Mortality Information System (MIS) and in the Notifiable Diseases Information System (NDIS). For the probabilistic relationship the following variables were selected: name, date of birth and gender. OpenRecLink software was used for linkage, Stata® for data analysis and TabWin for spatial distribution of deaths by EP. Deaths were described in relation to the characteristics of the place of occurrence, exposure circumstance, toxic agent group and final classification. The capture-recapture method was used to estimate the number of deaths, after the linkage of the databases. Results: The MIS data pointed to a mortality rate by EP of 5,2/100.000 inhabitants in São Paulo city in 2014. São Miguel administrative district presented the highest mortality rate 12,2/100.000 inhabitants. Most part of the deaths (n=412) were attested by IML doctor. The male gender was the one with the highest frequency (71 per cent ). The age group with the highest incidence was 20 to 39 years. It was possible to identify a large difference between the number of intoxication deaths recorded in the MIS (n=596) and the estimated (n=1.514,5) by the capture-recapture method. The mortality rate estimated by the capture-recapture method was 13,2/100.000 inhabitants. In this way, a 60,6 per cent underreporting of death was identified. Conclusions: The obtained results show that the mortality by EP is underestimated when compared to the calculated from the capture-recapture data. The linkage of databases is important to estimate the magnitude of the occurrence of death by EP. There is a need for formulation of public policies aimed at the practice of poisoning surveillance, qualification of health care professionals for the EP diagnosis and training of those responsible for case registration

Full textUniversal Access to health services and antiretroviral therapy were crucial in improving the survival or people living with HIV/AIDS (PLHA). The incidence of cronic comorbidities, however, have proportionally rised. Considering the AIDS epidemics in the state of Rio Grande do Sul, specifically in the city of Porto Alegre, it is important to determine the survival of PLHA in a local context, specially between individuals coinfected with TB. Data were obtained by the linkage of SIM and SINAN databases from 2007-2012. A COX regression model was used for the hazard ratios, and the Kaplan-Meier method in order to determine survival estimates. The resulting database had 1800 cases notified in 2007. Sixty percent were male, mostly of white race (67%), median age of 37 years old (IQR=14), mosto f them had low schooling. Around 70% acquired the vírus through sexual transmission. Compared to the total of cases, those notified by the death criteria have proportionally more individuals of the black race (46,1% and 32,5%, respectively) and more males (40% and 27,8%, respectively). The proportion of incomplete data is also higher for scholarity (72,1% and 68,7% respectively) and CD4+ T lymphocite cell count (76% e 68%, respectively). Blood transmission, black race and low scholarity were associated with a higher risk of death in the bivariate analysis. Female gender and age over 30 years were factors associated with a low risk of AIDS-related death. In the multivariate model black race, blood transmission of the vírus e low scholarity were factors associated with higher mortality. Mean survival was of 1495 days (95% CI 1449 – 1550). The proportion of incomplete data suggests that the linkage scales the underreporting but doesn’t qualify the surveillance process. Death criterion represents missed opportunities of interventions in preventable events, and might serve as negative indicator of the surveillance.

Os Sistemas de Informação em Saúde (SIS) contribuem para identificar problemas individuais e coletivos do quadro sanitário de uma população, propiciando elementos para análise da situação e subsidiando as ações. Por isto são considerados instrumentos de gestão e devem ser utilizados nas práticas de planejamento e execução das ações de vigilância sanitária (VISA) relativas à promoção, proteção e reabilitação da saúde e em sua avaliação. O estudo tem por objetivo descrever a situação da aplicação da informação em saúde no planejamento das ações de vigilância sanitária na gestão municipal. Mais especificamente identificar o grau de conhecimento dos profissionais sobre os SIS e descrever de que maneira os dados são utilizados pelos profissionais no planejamento. Trata-se de um estudo de caso, transversal e observacional, de caráter exploratório e descritivo, que apresenta abordagens quantitativas caracterizadas pela identificação dos dados existentes nos SIS e abordagens qualitativas que incluiram entrevistas com profissionais do setor e a apreciação da rede e da organização dos serviços por meio de análise documental. A análise e a interpretação dos dados são de natureza qualitativa. Os resultados apontam que os profissionais consideram o planejamento das ações de vigilância sanitária deficiente uma vez que não ocorre de maneira periódica, sistemática e uniforme com a utilização do enfoque estratégico situacional. Os entrevistados souberam definir SIS, mas demonstraram pouco conhecimento real dos vários sistemas existentes. Esses disponibilizam dados que dizem respeito à situação de saúde, entretanto a sua utilização não acontece para planejar as ações específicas de VISA, e uma das principais causas apontadas é a falta de conhecimento no manuseio destes sistemas pela equipe.

Full textThis study aimed to identify and analyze predictive factors of favorable treatment outcome related to pulmonary tuberculosis cases residing in Recife and diagnosed between 2001 and 2004. Initially, an exploratory study was carried out to identify lost data (blank, unknown and inconsistent) in the selected data in the Reportable Health Events Information System (SINAN): year of diagnosis; city of residence; treatment outcome; age; gender; education level; occupation; district of residence; form; type of entry; Supervised Treatment; date of diagnosis, start and end of treatment; health unit district; HIV and other health problems. Blank registers were found for Other Health Problems (42.85%) and Occupation (82.10%); unknown data were found for Education level (39.40%), Other Health Problems (39.73%) and Supervised Treatment (63.96%); and inconsistent data for Occupation (2.53%), Date of diagnosis (0.98%), Treatment start date (9.94%) and Treatment end date (17.66%). Then, we identified and analyzed predictive factors of favorable treatment outcome by means of uni and multivariate logistic regression methods. In univariate analysis, the following variables were associated with favorable treatment outcome: gender; age; education level; type of entry; supervised treatment; Time 1; Time 2 and health unit district. The variables that remained in the final adjusted multivariate model were: Age, 0 to 9 years (OR=4.27; p=0.001) and 10 to 19 years (OR=1.78; p=0.011) had a greater chance of cure than those older than 60 years; Education, 8 to 11 years (OR=1.52; p=0.049) had greater chance of cure than no education; Type of entry, new cases (OR=3.31; p<0.001) and relapse (OR=3.32; p<0.001) had a greater chance of cure than reentry after abandonment; Time 2, 5 ¾| 6 months (OR=9.15; p<0.001); 6 ¾| 9 months (OR=27.28; p<0.001) and More than 9 months (OR=24,78; p<0,001) had greater chance of cure than patients who terminated treatment in less time; Health Unit District, DS I (OR=1.60; p=0.018) and DS IV (OR=2.87; p<0.001) had a greater chance of cure than DS VI. We suggest that health services develop a care organization that is directed at individual needs, prioritizing groups with lower chances of cure, guaranteeing equity and consequent transformations in the city s epidemiological TB indices.

O trabalho se propôs estudar as fontes de informações de saúde e sua utilização por atores sociais, profissionais de saúde e comunidade local da região do Recreio dos Bandeirantes, uma área de expansão urbana acelerada, na cidade do Rio de Janeiro, com grande heterogeneidade geográfica e social. Estas informações constituem importantes instrumentos para o diagnóstico de saúde e o planejamento de políticas públicas locais. Para isso, é necessária uma abordagem interdisciplinar e participativa, envolvendo conceitos de vigilância da Saúde, território, informação em saúde e participação popular. Para realização dessa proposta foram utilizadas metodologias qualitativas e quantitativas, uma vez que se confrontaram dados de sistemas de informação em saúde e publicações na mídia, com entrevistas aos atores sociais mencionados. Foram utilizados mapas com a localização dos agravos, confeccionados com mínimos tratamentos cartográficos, com o intuito dos mesmos agirem como dispositivos contribuintes na comunicação junto aos personagens entrevistados. Com isso mapas dos agravos relacionados ao saneamento, como, dengue, leptospirose, esquistossomose e hepatites virais e os dados disponível sobre a saúde do bairro foram contrastados com a percepção que atores sociais constroem sobre áreas de risco. Concluindo assim, uma breve investigação da eficácia dos dados e seus usos na transformação e melhoria da saúde em nível local
This work aimed to study the sources of information about health and its use by social actors, health professionals and the local community in the region of the Recreio dos Bandeirantes, an area of rapid urban expansion, in the of Rio de Janeiro, with great heterogeneity geographical and social. This information constitutes important tools for the diagnosis of health and the planning of the local public policies. For this, it needs an interdisciplinary approach and participatory, involving concepts of health surveillance, territory, health information and public participation. For realization this proposal, were used qualitative and quantitative methodologies, since confronted information system data in health and media publications, interviews with social actors mentioned. It used maps with localization of the injuries, made with minimal cartographic treatment, with the intension of its act like device contributors in the communication with the characters interviewed. With this maps of the injuries related to sanitation such as dengue, leptospirosis, schistosomiasis, viral hepatitis and the available data about the district health were contrasted with the perception that social actors constructs about areas of risk. In conclusion therefore, a brief investigation of the effectiveness of the data and its uses in processing and improving health locally

Full textThis thesis aims to analyze the working conditions surveys (WCSs) in Latin America and to develop a proposal to improve the comparability of future surveys. First, we identified and examined the commonalities and differences in the methodologies of the WCSs available. Next, through a consensus process, a core questionnaire and basic methodological recommendations for future WCSs in the region were developed. In addition, we analyzed data from these surveys in a comparable sample of non-agricultural employees with written contract. Our findings can be summarized as follows: 1) WCSs in Latin America differed mainly in the covered population, the place of interview, and the question wording 2) some patterns of exposure to poor working and employment conditions, and health status were observed in the studied population 3) the final consensus included a core questionnaire for working, employment and health conditions, which comprises 77 questions organized in six dimensions, and main methodological recommendations such as conducting in-home interviews rather than workplace administered interviews. These results may contribute to improve occupational health surveillance in Latin America and the Caribbean.

Introduction: Toxoplasmosis is a universally distributed anthropozoonosis transmitted by the ingestion of tissue cysts or Toxoplasma gondii oocysts present in water, soil or contaminated food. In the literature there is description of outbreaks of toxoplasmosis, whose investigations could have been optimized with the use of geotechnologies. Geographical Information Systems (GIS) have been widely used to produce representative digital maps of situations of risk and health vulnerabilities that a population is exposed, being able to expand as information to health control, surveillance and prevention, or even, in case of outbreaks, to generate hypotheses regarding the probable source of infection. Objective: To analyze a toxoplasmosis outbreak in a residential condominium in São Luis – MA. Methodology: An ecological study based on a historical database of the investigation of an outbreak of toxoplasmosis occurred in 2006 in a residential condominium of São Luís - Maranhão. There were 110 people among residents, employees and domestic workers, 90 had their blood collected for serological analysis by ELISA (researcher technique), being classified as susceptible or not to infection and determined the attack rate of the outbreak. The software STATA 10 and Fisher's exact test were used for statistical analysis of the data. For geostatistical analysis, the Kernel estimator and the IDW interpolator with the help of ArcGIS® 10.1 e QGIS® 2.14 software were used. For a time analysis of the date of onset of symptoms, Excel® 2010. Results: There were 33 cases of acute or recent infection among 53 susceptible individuals, with attack rate of 62.26%. Women were more affected (60.61%).Among them one was pregnant and 15 patients of fertile age, a group that presented an attack rate of 65.21%. Among those susceptible, the use of the filter at the faucet was a factor associated with illness (p =0.049). Spatial analyzes in both techniques showed relatively similar patterns of case distribution, with the Kernel technique better representing the reality of the outbreak. The geostatistical tests did not reveal a proximity association in relation to only the distance (area) from the suspected source (condominium water box). Conclusion: The outbreak presented a high attack rate mainly among women of childbearing age, a group that deserves attention in the evaluation of the possibility of vertical transmission. The outbreak was likely caused by water transmission, from the contamination of the water box of the condominium. Digital maps of the cases and the susceptible ones served as a more didactic form of representation of the outbreak, as well as an example for the application of geostatistical techniques in order to complement an epidemiological analysis in other studies dealing with events in public health.
Introdução: A toxoplasmose é uma antropozoonose de distribuição universal transmitida pela ingestão de cistos teciduais ou de oocistos do Toxoplasma gondii presentes na água, no solo ou em alimentos contaminados. Na literatura há descrição de surtos de toxoplasmose cujas investigações poderiam ter sido otimizadas com o uso de geotecnologias. Sistemas de Informação Geográfica têm sido muito utilizados para produzirem mapas digitais representativos de situações de riscos e vulnerabilidades em saúde a que uma determinada população está exposta, podendo ampliar as informações necessárias para estratégias de controle de agravos, vigilância e prevenção em saúde, ou ainda em caso de surtos, gerar hipóteses em relação à provável fonte de infecção. Objetivo: Analisar um surto de toxoplasmose ocorrido num condomínio residencial de São Luís – MA. Metodologia: Trata-se de um estudo ecológico a partir de um banco de dados histórico da investigação de um surto de toxoplasmose ocorrido em 2006 em um condomínio residencial de São Luís - Maranhão. Dentre os 110 moradores, funcionários e empregadas domésticas, 90 tiveram sangue coletado para triagem sorológica pela técnica de ELISA, sendo classificados em suscetíveis ou não à infecção e determinado a taxa de ataque do surto. Utilizou-se o software STATA 10 e o teste exato de Fisher para análise estatística dos dados. Para análise geoestatística foi utilizado o estimador de Kernel e o interpolador IDW com auxílio dos software ArcGIS® 10.1e QGIS® 2.14. Para a análise temporal da data do início dos sintomas, o Excel® 2010. Resultados: Houve 33 casos de infecção aguda ou recente dentre 53 indivíduos suscetíveis, com taxa de ataque de 62,26%. As mulheres foram mais acometidas (60,61%), dentre elas uma estava grávida e 15 estavam em idade fértil, grupo que apresentou uma taxa de ataque de 65,21%. Dentre os suscetíveis, o uso de filtro de torneira foi um fator associado ao adoecimento (p=0,049). As análises espaciais em ambas as técnicas apresentaram padrões relativamente semelhantes de distribuição de casos, sendo que a técnica de Kernel representou melhor a realidade do surto. Os testes geoestatísticos não revelaram associação de proximidade em se tratando apenas da distância (área) com relação à fonte suspeita (caixa d’água do condomínio). Conclusão: O surto apresentou uma alta taxa de ataque principalmente entre as mulheres em idade fértil, grupo que merece destaque em decorrência da possibilidade de transmissão vertical. O surto foi provavelmente de veiculação hídrica, a partir da contaminação da caixa d’água do condomínio. Os mapas digitais dos casos e dos suscetíveis serviram como uma forma de representação mais didática do surto, bem como um exemplo para aplicação de técnicas geoestatísticas com intuito de complementar a análise epidemiológica em outros estudos que tratem de eventos em saúde pública.

Full textIntroduction: The Food and Nutrition Surveillance (FNS) is a set of surveillance strategies within the Health Surveillance, which includes the National Food and Nutrition Surveillance System (Sistema Nacional de Vigilância Alimentar e Nutricional - SISVAN), that aims at continuously monitoring and analyzing the food and nutritional status of the population attended by the Brazilian National Health System (Sistema Único de Saúde - SUS) and supporting actions, programs and policies. Objectives: to describe the Brazilian scientific literature on FNS and analyze to what extent the studies approach is linked/associated to the concept of the National Food and Nutrition Policy (2012); to analyze the coverage of the assessment of the nutritional status and the food intake of the users of the public health services registered on the Web SISVAN between 2008 and 2013. Methods: This study is organized in two methodological axes: a literature review on the concept of FNS present in recent Brazilian scientific production and two original ecological studies describing the assessment of the coverage of the nutritional status and food intake from the Web SISVAN data. Results: In the literature review, we found that the papers were mainly focused on the analysis of population surveys with smaller contribution of studies on health information systems and evaluation of health services. In the original studies, the average full coverage in Brazil ranged from 9.78 per cent to 14.92 per cent for the nutritional status and from 0.13 per cent to 0.41 per cent for the food intake. Both showed statistically significant trends of increase and differences between the Brazilian Federal Units and macro-regions. The FNS was prioritized for mother-child pairs, priority public of the Bolsa Familia Program, in the case of nutrition status data, and related to the presence of nutritionists in the primary healthcare services, in the case of food intake data. Conclusion: We presented an overview of recent scientific literature on FNS and of the monitoring of nutritional status and food intake in the Brazilian health services, revealing contexts where resources need to be mobilized to improve the FNS.

Full textO propósito desta Tese foi detectar e caracterizar áreas sob alto risco para leishmaniose visceral (LV) e descrever os padrões de ocorrência e difusão da doença, entre os anos de 1993 a 1996 e 2001 a 2006, em Teresina, Piauí, por meio de métodos estatísticos para análise de dados espaciais, sistemas de informações geográficas e imagens de sensoriamento remoto. Os resultados deste estudo são apresentados na forma de três manuscritos. O primeiro usou análise de dados espaciais para identificar as áreas com maior risco de LV na área urbana de Teresina entre 2001 e 2006. Os resultados utilizando razão de kernels demonstraram que as regiões periféricas da cidade foram mais fortemente afetadas ao longo do período analisado. A análise com indicadores locais de autocorrelação espacial mostrou que, no início do período de estudo, os agregados de alta incidência de LV localizavam-se principalmente na região sul e nordeste da cidade, mas nos anos seguintes os eles apareceram também na região norte da cidade, sugerindo que o padrão de ocorrência de LV não é estático e a doença pode se espalhar ocasionalmente para outras áreas do município. O segundo estudo teve como objetivo caracterizar e predizer territórios de alto risco para ocorrência da LV em Teresina, com base em indicadores socioeconômicos e dados ambientais, obtidos por sensoriamento remoto. Os resultados da classificação orientada a objeto apontam a expansão da área urbana para a periferia da cidade, onde antes havia maior cobertura de vegetação. O modelo desenvolvido foi capaz de discriminar 15 conjuntos de setores censitário (SC) com diferentes probabilidades de conterem SC com alto risco de ocorrência de LV. O subconjunto com maior probabilidade de conter SC com alto risco de LV (92%) englobou SC com percentual de chefes de família alfabetizados menor que a mediana (≤64,2%), com maior área coberta por vegetação densa, com percentual de até 3 moradores por domicílio acima do terceiro quartil (>31,6%). O modelo apresentou, respectivamente, na amostra de treinamento e validação, sensibilidade de 79% e 54%, especificidade de 74% e 71%, acurácia global de 75% e 67% e área sob a curva ROC de 83% e 66%. O terceiro manuscrito teve como objetivo avaliar a aplicabilidade da estratégia de classificação orientada a objeto na busca de possíveis indicadores de cobertura do solo relacionados com a ocorrência da LV em meio urbano. Os índices de acurácia foram altos em ambas as imagens (>90%). Na correlação da incidência da LV com os indicadores ambientais verificou-se correlações positivas com os indicadores Vegetação densa, Vegetação rasteira e Solo exposto e negativa com os indicadores Água, Urbana densa e Urbana verde, todos estatisticamente significantes. Os resultados desta tese revelam que a ocorrência da LV na periferia de Teresina está intensamente relacionada às condições socioeconômicas inadequadas e transformações ambientais decorrentes do processo de expansão urbana, favorecendo a ocorrência do vetor (Lutzomyia longipalpis) nestas regiões.
The objective of this Thesis was to detect and characterize areas under high risk of visceral leishmaniasis (VL) and to describe patterns of occurrence and diffusion of the disease, between the years of 1993 1996 and 2001 the 2006, in Teresina, Piauí, Brazil, using statistical methods for spatial data analysis, geographic information systems and remote sensing. The results of this study are presented in three manuscripts. The first used spatial analysis to identify areas at greatest risk of VL in the urban area of Teresina, Brazil from 2001 to 2006. The results from kernel ratios showed that peripheral census tracts were the most heavily affected. Local spatial analysis showed that in the beginning of the study period local clusters of high incidence of VL were mostly located in the South and Northeast parts of the city, but in the following years those clusters appeared also in the North region of the city, suggesting that the pattern of VL occurrence is not static and disease may occasionally spread out to other areas of the municipality. The second study aimed to characterize and predict areas at high risk for occurrence of VL in Teresina, based on socioeconomic and environmental indicators obtained by remote sensing. The results of object-oriented classification indicate the expansion of the urban area to the periphery of the city, where larger areas covered by vegetation were usually seen. The model developed was able to discriminate 15 subsets of census tracts (SC) with different probabilities of containing SC with high risk of VL occurrence. The subset with higher probability of containing SC with high risk of VL (92%) encompassed SC with percentage of literate heads-of-households less than the median (≤64.2%), with greater area covered by dense vegetation, with percentage of up to 3 people per household above the third quartile (>31.6%). The model presented, respectively, in the validation and training samples, sensitivity of 79% and 54%, specificity of 75% and 71% global accuracy of 75% and 67% and area under the ROC curve of 83% and 66%. The third manuscript aimed to evaluate the applicability of object-oriented classification in searching for possible indicators of "land cover" related to the occurrence of VL on the urban environment. Accuracy indices were high for both images (>90%). In the correlation analysis, the incidence of VL was found to be positively correlated with dense vegetation, vegetation and exposed soil and negatively correlated with water, dense urban and green urban indicators, all statistically significant. The results of this thesis reveal that the occurrence of VL on the periphery of Teresina is intensely related to inadequate socioeconomic conditions and environmental modifications arising from the process of urban expansion, both favoring the occurrence of the vector (Lutzomyia longipalpis) in these regions.

Find full textIn recent years, there has been an increase in the popularity of wearable sensors such as electroencephalography (EEG) sensors, electromyography (EMG) sensors, gyroscopes, accelerometers, and photoplethysmography (PPG) sensors. This work is focused on PPG sensors, which are used to measure heart rate in real time. They are currently used in many commercial products such as Fitbit Watch and Muse Headband. Due to their low cost and relative implementation simplicity, they are easy to add to custom-built wearable devices.
We built an Arduino-based wearable wrist sensor-kit that consists of a PPG sensor in addition to other low cost commercial biosensors to measure biosignals such as pulse rate, skin temperature, skin conductivity, and hand motion. The purpose of the sensor-kit is to analyze the effects of stress on students in a classroom based on changes in their biometric signals. We noticed some failures in the measured PPG signal, which could negatively affect the accuracy of our analysis. We conjectured that one of the causes of failure is movement. Therefore, in this thesis, we build automatic failure detection methods and use these methods to study the effect of movement on the signal.
Using the sensor-kit, PPG signals were collected in two settings. In the first setting, the participants were in a still sitting position. These measured signals were manually labeled and used in signal analysis and method development. In the second setting, the signals were acquired in three different scenarios with increasing levels of activity. These measured signals were used to investigate the effect of movement on the reliability of the PPG sensor.
Four types of failure detection methods were developed: Support Vector Machines (SVM), Deep Neural Networks (DNN), K-Nearest Neighbor (K-NN), and Decision Trees. The classification accuracy is evaluated by comparing the resulting Receiver Operating Characteristic (ROC) curves, Area Above the Curve (AAC), as well as the duration of failure and non-failure sequences. The DNN and Decision Tree results are found to be the most promising and seem to have the highest error detection accuracy.
The proposed classifiers are also used to assess the reliability of the PPG sensor in the three activity scenarios. Our findings indicate that there is a significant presence of failures in the measured PPG signals at rest, which increases with movement. They also show that it is hard to obtain long sequences of pulses without failure. These findings should be taken into account when designing wearable systems that use heart rate values as input.

Full textIntroduction: Cancer registries collect tumor-related data to monitor incident rates and support population-based research. A common concern with using population-based registry data for research is reporting timeliness. Data timeliness have been recognized as an important data characteristic by both the Centers for Disease Control and Prevention (CDC) and the Institute of Medicine (IOM). Yet, few recent studies in the United States (U.S.) have systemically measured timeliness. The goal of this research is to evaluate the quality of cancer data and examine methods by which the reporting process can be improved. The study aims are: 1- evaluate the timeliness of cancer cases at the Indiana State Department of Health (ISDH) Cancer Registry, 2- identify the perceived barriers and facilitators to timely reporting, and 3- reengineer the current reporting process to improve turnaround time. Method: For Aim 1: Using the ISDH dataset from 2000 to 2009, we evaluated the reporting timeliness and subtask within the process cycle. For Aim 2: Certified cancer registrars reporting for ISDH were invited to a semi-structured interview. The interviews were recorded and qualitatively analyzed. For Aim 3: We designed a reengineered workflow to minimize the reporting timeliness and tested it using simulation. Result: The results show variation in the mean reporting time, which ranged from 426 days in 2003 to 252 days in 2009. The barriers identified were categorized into six themes and the most common barrier was accessing medical records at external facilities. We also found that cases reside for a few months in the local hospital database while waiting for treatment data to become available. The recommended workflow focused on leveraging a health information exchange for data access and adding a notification system to inform registrars when new treatments are available.

Full textIdentifying spatial and temporal patterns of disease occurrence by mapping the residential locations of affected people can provide information that informs response by public health practitioners and improves understanding in epidemiological research. A common method of locating patients at the individual level is geocoding residential addresses stored in electronic medical records (EMRs) using address matching procedures in a geographic information system (GIS). While the process of geocoding is becoming more common in public health studies, few researchers take the time to examine the effects of using different address databases on match rate and positional accuracy of the geocoded results. This research examined and compared accuracy and match rate resulting from four commonly-used geocoding databases applied to sample of 59,341 subjects residing in and around Marion County/ Indianapolis, IN. The results are intended to inform researchers on the benefits and downsides to their selection of a database to geocode patient addresses in EMRs.
