Sensitivity of Guillain-Barre Syndrome Surveillance in the Brazilian Federal District, using the Capture-Recapture Method.

INTRODUCTION: Guillain-Barre Syndrome (GBS) is an acute immune-mediated polyneuropathy that compromises the peripheral and cranial nerves. It is characterized by rapid-onset paresthesia accompanied by progressive weakness in the lower extremities followed by symmetric ascending paralysis. METHODOLOGY: assessment of sensitivity to detect GBS between March 2017 and May 2019 in a public referral hospital, using the capture-recapture method based on the Chapman estimator and comparing three GBS data sources: the hospital-based sentinel surveillance system (VSBH), Human Immunoglobulin Dispensing Records System (RDIH), and Hospital Information System (SIH). RESULTS: A total of 259 possible cases were identified (captured). Of these, 58 were confirmed and most resided in the Federal District. The VSBH showed the greatest sensitivity in case identification. The temporal distribution of cases showed periods with no cases identified, and more were registered during the rainy season from October to May, when high temperatures also occur. CONCLUSIONS: Increased circulation of arboviruses and gastrointestinal infections during the rainy season may explain the greater concentration of GBS cases. It is important to note that one-third of the cases identified in the different data sources do not converge, demonstrating that no single surveillance system is 100% effective. The severity and possible increase in cases related to GBS demonstrates the need for an improved surveillance system capable of monitoring and following-up cases involving neurological syndromes, regardless of the event preceding infection.

Observation Encounters and Length of Stay Benchmarking in Children's Hospitals.

BACKGROUND AND OBJECTIVES: Length of stay (LOS) is a common benchmarking measure for hospital resource use and quality. Observation status (OBS) is considered an outpatient service despite the use of the same facilities as inpatient status (IP) in most children's hospitals, and LOS calculations often exclude OBS stays. Variability in the use of OBS by hospitals may significantly impact calculated LOS. We sought to determine the impact of including OBS in calculating LOS across children's hospitals. METHODS: Retrospective cohort study of hospitalized children (age <19 years) in 2017 from the Pediatric Health Information System (Children's Hospital Association, Lenexa, KS). Normal newborns, transfers, deaths, and hospitals not reporting LOS in hours were excluded. Risk-adjusted geometric mean length of stay (RA-LOS) for IP-only and IP plus OBS was calculated and each hospital was ranked by quintile. RESULTS: In 2017, 45 hospitals and 625 032 hospitalizations met inclusion criteria (IP = 410 731 [65.7%], OBS = 214 301 [34.3%]). Across hospitals, OBS represented 0.0% to 60.3% of total discharges. The RA-LOS (SD) in hours for IP and IP plus OBS was 75.2 (2.6) and 54.3 (2.7), respectively (P < .001). For hospitals reporting OBS, the addition of OBS to IP RA-LOS calculations resulted in a decrease in RA-LOS compared with IP encounters alone. Three-fourths of hospitals changed ≥1 quintile in LOS ranking with the inclusion of OBS. CONCLUSIONS: Children's hospitals exhibit significant variability in the assignment of OBS to hospitalized patients and inclusion of OBS significantly impacts RA-LOS calculations. Careful consideration should be given to the inclusion of OBS when determining RA-LOS for benchmarking, quality and resource use measurements.

Solid organ transplantation in Brazil: a descriptive study of distribution and access inequalities across the Brazilian territory, 2001-2017. / Transplantes de órgãos sólidos no Brasil: estudo descritivo sobre desigualdades na distribuição e acesso no território brasileiro, 2001-2017.

OBJECTIVE: to describe the distribution of solid organ transplants in Brazil, as well as information about the waiting list (demand) and origin of transplant patients by organ type and Federative Unit, from 2001 to 2017. METHODS: this was a descriptive study using data from State Transplantation Centers, the Brazilian Organ Transplant Association, and the Brazilian National Health System Hospital Information System (SIH/SUS). RESULTS: 153 transplant units were identified in 2017, with only 11.8% located in the Northern and Midwest regions; within the study period, 99,805 transplants were performed, ranging from 3,520 (2001) to 8,669 (2017); the highest number of transplants was concentrated in the Southern and Southeastern regions. CONCLUSION: there are inequalities in transplantation access, possibly due to lack of uniformity in service distribution.

Technology-facilitated care coordination in rural areas: What is needed?

BACKGROUND: Health is poorer in rural areas and a major challenge is care coordination for complex chronic conditions. The HITECH and 21st Century Cure Acts emphasize health information exchange which underpins activities required to improve care coordination. OBJECTIVE AND METHODS: Using semi-structured interviews and surveys, we examined how providers experience electronic health information exchange during care coordination since these Acts were implemented, with a focus on rural settings where health disparities exist. We used a purposive sample that included primary care, acute care hospitals, and community health services in the United States. FINDINGS: We identified seven themes related to care coordination and information exchange: 'insufficient trust of data'; 'please respond'; 'just fax it'; 'care plans'; 'needle in the haystack'; 're-documentation'; and 'rural reality'. These gaps were magnified when information exchange was required between unaffiliated electronic health records (EHRs) about shared patients, which was more pronounced in rural settings. CONCLUSION: Policy and incentive modifications are likely needed to overcome the observed health information technology (HIT) shortcomings. Rural settings in the United States accentuate problems that can be addressed through international medical informatics policy makers and the implementation and evaluation of interoperable HIT systems.

Monitoring severe acute maternal morbidity across Europe: A feasibility study.

BACKGROUND: Monitoring severe acute maternal morbidity (SAMM) appears essential for optimising care and informing health care policies, especially given changes in obstetric practices and mother profiles. International comparisons can identify areas where improvement is needed, but the comparability of indicators must be evaluated. OBJECTIVE: To assess the feasibility of monitoring SAMM using common definitions from hospital discharge databases across Europe. METHODS: We used hospital discharge data in eight countries (2 826 868 deliveries) to identify women with SAMM among all hospitalisations of women of reproductive age admitted for antenatal or delivery care. Five SAMM indicators were investigated: eclampsia, septicaemia, hysterectomy, hysterectomy associated with a diagnosis of obstetric haemorrhage, and red blood cell (RBC) transfusion associated with a diagnosis of obstetric haemorrhage. Between-country variation was described, by the ratio of the highest to lowest rates, while external validation was assessed by comparing with population-based studies on maternal morbidity. RESULTS: Ratios for hysterectomy and red blood cell (RBC) transfusion in the context of obstetric haemorrhage were 1:2.1 and 1:3.5, respectively. High values of hysterectomy and low values of transfusion were both consistent with high maternal mortality from haemorrhage (France, Italy, Portugal). Ratios across countries were relatively low for eclampsia (1:3.4) but very high for septicaemia (1:22.5). Compared to population-based morbidity estimates, eclampsia was over-reported in hospital databases whereas the two indicators of severe haemorrhage had good external validity. CONCLUSIONS: In association with diagnosis codes indicating obstetric haemorrhage, hysterectomy and RBC transfusion appear to be good candidates for surveillance of maternal morbidity in Europe.

Standardised mortality ratios as a user-friendly performance metric and trigger for quality improvement in a Flemish hospital network: multicentre retrospective study.

OBJECTIVE: To illustrate the development and use of standardised mortality rates (SMRs) as a trigger for quality improvement in a network of 27 hospitals. DESIGN: This research was a retrospective observational study. The primary outcome was in-hospital mortality. SMRs were calculated for All Patient Refined-Diagnosis-Related Groups (APR-DRGs) that reflect 80% of the Flemish hospital network mortality. Hospital mortality was modelled using logistic regression. The metrics were communicated to the member hospitals using a custom-made R-Shiny web application showing results at the level of the hospital, patient groups and individual patients. Experiences with the metric and strategies for improvement were shared in chief medical officer meetings organised by the Flemish hospital network. SETTING: 27 Belgian hospitals. PARTICIPANTS: 1 198 717 hospital admissions for registration years 2009-2016. RESULTS: Patient gender, age, comorbidity as well as admission source and type were important predictors of mortality. Altogether the SMR models had a C-statistic of 88%, indicating good discriminatory capability. Seven out of ten APR-DRGs with the highest percentage of hospitals statistically significantly deviating from the benchmark involved malignancy. The custom-built web application and the trusted environment of the Flemish hospital network created an interoperable strategy to get to work with SMR findings. Use of the web application increased over time, with peaks before and after key discussion meetings within the Flemish hospital network. A concomitant reduction in crude mortality for the selected APR-DRGs from 6.7% in 2009 to 5.9% in 2016 was observed. CONCLUSIONS: This study reported on the phased approach for introducing SMR reporting to trigger quality improvement. Prerequisites for the successful use of quality metrics in hospital benchmarks are a collaborative approach based on trust among the participants and a reporting platform that allows stakeholders to interpret and analyse the results at multiple levels.

Envelhecimento populacional e gastos com internação do SUS: uma análise realizada para o Brasil entre 2000 e 2010 / Population aging and hospitalization expenses of SUS: an analysis performed for Brazil between 2000 and 2010 / Envejecimiento de la población y el gasto con la hospitalización del SUS: un análisis para Brasil entre 2000 y 2010

Resumo A população mundial vem experimentando um processo gradativo de envelhecimento de sua estrutura etária, em função da queda acentuada da fecundidade e da mortalidade nas últimas décadas. Esse processo, que está em curso em praticamente todos os países do mundo, traz à tona a preocupação com o crescimento das despesas em saúde. O objetivo do presente artigo é avaliar o efeito das mudanças da estrutura etária nos gastos com internação do Sistema Único de Saúde do Brasil. Para tanto, foi realizada uma decomposição dos gastos em saúde, utilizando o método Tchoe e Nam, adaptado para a realidade do caso brasileiro. A decomposição também é feita considerando três grupos de doenças: infecciosas e parasitárias, neoplasias e circulatórias. Os dados são provenientes do Sistema de Informações Hospitalares (SIH-SUS). De forma geral, os resultados encontrados mostram a importância da variação na estrutura etária (envelhecimento populacional) nos gastos das internações hospitalares do SUS entre 2000 e 2010, principalmente para os grupos de doenças associados a uma população mais envelhecida, doenças circulatórias e neoplasia.

Abstract The world population is experiencing a gradual process of aging of its age structure, due to the sharp decline in fertility and mortality in recent decades. This process, in course practically in all countries of the world, brings up the concern about health spending growth. The aim of this paper is to evaluate the effect of the changes in the age structure on hospitalization spending of the Sistema Único de Saúde (SUS) in Brazil. To achieve this goal a breakdown of health expenditures was performed using Tchoe and Nam method, adapted to the reality of the Brazilian case. The decomposition is also performed considering three groups of diseases: infectious and parasitic diseases, cancer and circulatory. The data are from the Sistema de Informação Hospitalar (SIH-SUS). In general, the results of the decomposition show the importance of variation in age structure (aging population) on SUS hospitalizations spending between 2000 and 2010, especially for groups of diseases associated with an aging population, such as circulatory diseases and cancer.

The Decline of the Autopsy in Rhode Island and Nationwide: Past Trends and Future Directions.

The autopsy has long been a fundamental aspect of medical practice and research. However, in the last 50 years, the proportion of deaths for which an autopsy is performed has decreased dramatically. Here we examine some of the reasons for the decline of the autopsy, as well as several interventions that have been proposed to revive it. We also present autopsy utilization data from the Lifespan system, which mirrors nationwide trends. [Full article available at http://rimed.org/rimedicaljournal-2016-10.asp].

[Morbidity profile and hospital expenses with elderly patients in Paraná State, Brazil, 2008-2012]. / Perfil de morbidade e gastos hospitalares com idosos no Paraná, Brasil, entre 2008 e 2012.

Growth in the elderly population has increased both the demand for health services and healthcare expenses, with relevant consequences for economic stability. The current study aimed to analyze the morbidity profile and hospital expenses with elderly patients in relation to socioeconomic and demographic conditions in Paraná State, Brazil, from 2008 to 2012, applying principal components analysis and groupings. Regions with higher and lower economic and human development showed high prevalence of hospitalizations and costs pertaining to the circulatory and respiratory systems and cardiac diseases for males and females. In regions with intermediary development, diseases of the nervous system in men and of the circulatory system in women had the highest morbidity and hospital expenses. Thus, measures for prevention and health promotion in this elderly population should be targeted to regional investigations.

[Variation in hospital performance according to payment sources in the states of São Paulo and do Rio Grande do Sul, Brazil]. / Variação do desempenho hospitalar segundo fontes de pagamento nos estados de São Paulo e Rio Grande do Sul, Brasil.

In Brazil, the combined presence of public and private interests in financing and provision of healthcare services stands out clearly in hospital care. Financing arrangements adopted by hospitals (the public Brazilian Unified National Health System - SUS and/or health plans and/or out-of-pocket payment) can affect quality of care. Studies have analyzed the hospital standardized mortality ratio (HSMR) in relation to quality improvements. The objective was to analyze HSMR according to source of payment for the hospitalization and the hospital's financing arrangement. The study analyzed secondary data and causes that accounted for 80% of hospital deaths. HSMR was calculated for each hospital and payment source. Hospitals with worse-than-expected performance (HSMR > 1) were mostly large public hospitals. HSMR was higher in the SUS, including between admissions in the hospital. Despite the study's limitations, the findings point to inequalities in results of care. Efforts are needed to improve the quality of hospital services, regardless of the payment sources.

Evaluation of Acceptance of Nursing Information System in a German and American Hospital.

Nursing Information Systems (NIS) are not well-adopted and accepted in Germany. The evaluation of a NIS deployment in a German University Hospital supports this assumption. A second side study in the US should point out the differences regarding the technical and organizational differences. We use a questionnaire including standardized instruments like the Unified Theory of Acceptance (UTAUT). Results indicated that nurses in Germany compared to in the US do not use nursing process documentation to the same extent. The main reasons behind the low usage in comparison with the US are deficits in ease-of-use, system performance and the high expenditure of time and paper work for charting nursing plans.

Event Reports Promoting Root Cause Analysis.

Improving health is the sole objective of medical care. Unfortunately, mishaps or patient safety events happen during the care. If the safety events were collected effectively, they would help identify patterns, underlying causes, and ultimately generate proactive and remedial solutions for prevention of recurrence. Based on the AHRQ Common Formats, we examine the quality of patient safety incident reports and describe the initial data requirement that can support and accelerate effective root cause analysis. The ultimate goal is to develop a knowledge base of patient safety events and their common solutions which can be readily available for sharing and learning.

Assessment of Pharmacy Information System Performance in Three Hospitals in Eastern Province, Saudi Arabia.

The pharmacy information system is one of the central pillars of a hospital information system. This research evaluated a pharmacy information system according to six aspects of the medication process in three hospitals in Eastern Province, Saudi Arabia. System administrators were interviewed to determine availability of functionalities. Then, system users within the hospital were targeted to evaluate their level of usage of these functionalities. The study was cross-sectional. Two structured surveys were designed. The overall response rate of hospital users was 31.7 percent. In all three hospitals studied, the electronic health record is hybrid, implementation has been completed and the system is running, and the systems have computerized provider order entry and clinical decision support. Also, the pharmacy information systems are integrated with the electronic health record, and computerized provider order entry and almost all prescribing and transcription functionalities are available; however, drug dispensing is a mostly manual process. However, the study hospitals do not use barcode-assisted medication administration systems to verify patient identity and electronically check dose administration, and none of them have computerized adverse drug event monitoring that uses the electronic health record. The numbers of users who used different functionalities most or all of the time was generally low. The highest frequency of utilization was for patient administration records (56.8 percent), and the lowest was for linkage of the pharmacy information system to pharmacy stock (9.1 percent). Encouraging users to use different functionalities was highly recommended.

Variação do desempenho hospitalar segundo fontes de pagamento nos estados de São Paulo e Rio Grande do Sul, Brasil / Variation in hospital performance according to payment sources in the states of São Paulo and do Rio Grande do Sul, Brazil / Variación del desempeño hospitalario según fuentes de pago en los estados de São Paulo y de Río Grande do Sul, Brasil

Resumo: No Brasil, a convivência público-privado no financiamento e na prestação do cuidado ganha nítidos contornos na assistência hospitalar. Os arranjos de financiamento adotados pelos hospitais (Sistema Único de Saúde - SUS e/ou planos de saúde e/ou pagamento particular) podem afetar a qualidade do cuidado. Alguns estudos buscam associar a razão de mortalidade hospitalar padronizada (RMHP) a melhorias na qualidade. O objetivo foi analisar a RMHP segundo fonte de pagamento da internação e arranjo de financiamento do hospital. Analisaram-se dados secundários e causas responsáveis por 80% dos óbitos hospitalares. A RMHP foi calculada para cada hospital e fonte de pagamento. Hospitais com desempenho pior que o esperado (RMHP > 1) foram majoritariamente públicos de maior porte. A RMHP nas internações SUS foi superior, inclusive entre internações no mesmo hospital. Apesar dos limites, os achados indicam iniquidades no resultado do cuidado. Esforços voltados para a melhoria da qualidade de serviços hospitalares, independentemente das fontes de pagamento, são prementes.

The Role of Hospital Information Systems in Universal Health Coverage Monitoring in Rwanda.

In this retrospective study, the authors monitored the patient health coverage in 6 Rwandan hospitals in the period between 2011 and 2014. Among the 6 hospitals, 2 are third level hospitals, 2 district hospitals and 2 private hospitals. Patient insurance and financial data were extracted and analyzed from OpenClinic GA, an open source hospital information system (HIS) used in those 6 hospitals. The percentage of patients who had no health insurer globally decreased from 35% in 2011 to 15% in 2014. The rate of health insurance coverage in hospitals varied between 75% in private hospitals and 84% in public hospitals. The amounts paid by the patients for health services decreased in private hospitals to 25% of the total costs in 2014 (-7.4%) and vary between 14% and 19% in public hospitals. Although the number of insured patients has increased and the patient share decreased over the four years of study, the patients' out-of-pocket payments increased especially for in-patients. This study emphasizes the value of integrated hospital information systems for this kind of health economics research in developing countries.

Improving Hospital-Wide Early Resource Allocation through Machine Learning.

The objective of this paper is to evaluate the extent to which early determination of diagnosis-related groups (DRGs) can be used for better allocation of scarce hospital resources. When elective patients seek admission, the true DRG, currently determined only at discharge, is unknown. We approach the problem of early DRG determination in three stages: (1) test how much a Naïve Bayes classifier can improve classification accuracy as compared to a hospital's current approach; (2) develop a statistical program that makes admission and scheduling decisions based on the patients' clincial pathways and scarce hospital resources; and (3) feed the DRG as classified by the Naïve Bayes classifier and the hospitals' baseline approach into the model (which we evaluate in simulation). Our results reveal that the DRG grouper performs poorly in classifying the DRG correctly before admission while the Naïve Bayes approach substantially improves the classification task. The results from the connection of the classification method with the mathematical program also reveal that resource allocation decisions can be more effective and efficient with the hybrid approach.

A Trial of Nursing Cost Accounting using Nursing Practice Data on a Hospital Information System.

Hospital administration is very important and many hospitals carry out activity-based costing under comprehensive medicine. However, nursing cost is unclear, because nursing practice is expanding both quantitatively and qualitatively and it is difficult to grasp all nursing practices, and nursing cost is calculated in many cases comprehensively. On the other hand, a nursing information system (NIS) is implemented in many hospitals in Japan and we are beginning to get nursing practical data. In this paper, we propose a nursing cost accounting model and we simulate a cost by nursing contribution using NIS data.
