Improvements in data completeness in health information systems reveal racial inequalities: longitudinal national data from hospital admissions in Brazil 2010-2022.

BACKGROUND: Race and ethnicity are important drivers of health inequalities worldwide. However, the recording of race/ethnicity in data systems is frequently insufficient, particularly in low- and middle-income countries. The aim of this study is to descriptively analyse trends in data completeness in race/color records in hospital admissions and the rates of hospitalizations by various causes for Blacks and Whites individuals. METHODS: We conducted a longitudinal analysis, examining hospital admission data from Brazil's Hospital Information System (SIH) between 2010 and 2022, and analysed trends in reporting completeness and racial inequalities. These hospitalization records were examined based on year, quarter, cause of admission (using International Classification of Diseases (ICD-10) codes), and race/color (categorized as Black, White, or missing). We examined the patterns in hospitalization rates and the prevalence of missing data over a period of time. RESULTS: Over the study period, there was a notable improvement in data completeness regarding race/color in hospital admissions in Brazil. The proportion of missing values on race decreased from 34.7% in 2010 to 21.2% in 2020. As data completeness improved, racial inequalities in hospitalization rates became more evident - across several causes, including assaults, tuberculosis, hypertensive diseases, at-risk hospitalizations during pregnancy and motorcycle accidents. CONCLUSIONS: The study highlights the critical role of data quality in identifying and addressing racial health inequalities. Improved data completeness has revealed previously hidden inequalities in health records, emphasizing the need for comprehensive data collection to inform equitable health policies and interventions. Policymakers working in areas where socioeconomic data reporting (including on race and ethnicity) is suboptimal, should address data completeness to fully understand the scale of health inequalities.

The Impact of the COVID-19 Pandemic on Surgical Services in Brazil's Healthcare System: A Retrospective Cross-Sectional Study.

Background The coronavirus disease 2019 (COVID-19) pandemic provoked disruptions in healthcare delivery, leading to the cancellation and postponement of various health services, including surgery. Numerous countries closed their borders and established laws mandating the use of face masks and social distancing and enforced lockdowns, and various activities were constrained. Brazil, the largest and most populous country in Latin America, also experienced a rapid and sustained surge in infections and deaths. Brazil was the most severely impacted nation in Latin America. The impact of the pandemic on surgical services in Brazil has not been adequately studied since most studies only cover the early phases of the pandemic. Thus, this study aimed to assess the impact of the COVID-19 pandemic on surgical services throughout the entire period. Methods A retrospective cross-sectional design was used to examine surgical cases from 2019 to 2022 and compared the following indicators: (1) number of hospital admissions, (2) length of hospital stay (LOS) (in days), and (3) volume of urgent and elective procedures. Data was divided into four time periods, pre-pandemic (March-December 2019), pandemic (March-December 2020), recovery (March-December 2021), and post-pandemic (March-December 2022), and was analyzed for the number of admissions and LOS based on surgical procedures performed by stratifying according to region, sex, age, and type of surgery (urgent versus elective). Results The number of admissions for surgical procedures ranged between 859,646 and 4,015,624 for 2019, 686,616 and 3,419,234 for 2020, 787,791 and 3,829,019 for 2021, and 760,512 and 3,857,817 for 2022 for the category of region; 4,260,900 and 5,991,775 for 2019, 3,594,117 and 4,984,710 for 2020, 4,182,640 and 5,590,808 for 2021, and 4,077,651 and 5,561,928 for 2022 for the category of sex; and 2,170,288 and 3,186,117 for 2019, 1,516,830 and 2,825,189 for 2020, 1,748,202 and 3,030,272 for 2021, and 1,900,023 and 2,859,179 for 2022 for the category of age. The variable age showed a comparable trend, albeit with an expressive decline for surgeries in the age range of 0-19 years. The LOS (in days) for surgical procedures ranged between 110,157 and 910,846 for 2019, 58,562 and 897,734 for 2020, 67,926 and 904,137 for 2021, and 100,467 and 823,545 for 2022. Thoracic surgery indicated no statistically significant difference in the number of admissions and LOS. Elective surgeries had a decline in the number of admissions and LOS, a 13% and 9.3% decline between 2019 and 2020, respectively. Urgent surgeries experienced a slight decrease in admissions and LOS, with a decline of 2.4% and 2.8% between 2019 and 2020, respectively. Conclusions Population characteristics, such as age, sex, and region, showed decreased hospital admissions during the pandemic, followed by a recovery toward pre-pandemic levels afterward. The number of surgical admissions and the length of hospital stays decreased during the pandemic but gradually returned to pre-pandemic levels in the recovery and post-pandemic phases. Notably, thoracic surgery remained statistically consistent across all periods, indicating its emergency nature compared to other surgeries. Thus, we conclude that the pandemic had minimal impact on thoracic surgery cases, contributing to a stable trend.

Analyzing the relationship between air temperature and respiratory morbidity in children and the elderly in Porto Alegre, Brazil, before and during the COVID-19 pandemic.

The aim of the study was to analyze the relationship between air temperature data against hospital admissions due to respiratory diseases of children (under five years of age) and the elderly (over 65) in subtropical Porto Alegre, Brazil, comparing outcomes for 3 sequential years, 2018-2020, pre- and post-COVID 19 pandemic. Meteorological and hospital admission (HA) data for Porto Alegre, marked by a Koeppen-Geiger's Cfa climate type with well-defined seasons, were used in the analyses. HA was obtained for respiratory diseases (J00-99, according to the International Classification of Diseases, ICD-10) from the Brazilian DATASUS (Unified Health System database). We performed correlation analysis between variables (HA versus air temperature and heat stress) in order to identify existing relationships and lag effects (between meteorological condition and morbidity). Relative risk (RR) was also obtained for the two age groups during the three years. Results showed that the pandemic year disrupted observed patterns of association between analyzed variables, with either very low or non-existent correlations.

Hospitalizations from Birth to 28 Years in a Population Cohort of Individuals Born with Five Rare Craniofacial Anomalies in Western Australia.

OBJECTIVE: To describe trends, age-specific patterns, and factors influencing hospitalizations for 5 rare craniofacial anomalies (CFAs). METHODS: Data on livebirths (1983-2010; n = 721 019) including rare CFA (craniofacial microsomia, mandibulofacial dysostosis, Pierre Robin sequence, Van der Woude syndrome, and frontonasal dysplasia), episodes of death, and demographic and perinatal factors were identified from the Western Australian Register of Developmental Anomalies, Death Registrations and Midwives Notification System. Information on incident craniofacial and noncraniofacial related admissions, length of hospital stay, and intensive care and emergency-related admissions were identified using principal diagnosis and procedural codes were extracted from the Hospital Morbidity Data Collection and linked to other data sources. Associations of hospitalizations by age groups as well as demographic and perinatal factors were expressed as incidence rate ratio (IRR). RESULTS: The incident hospitalizations were 3 times as high for rare CFA (IRR 3.22-3.72) throughout childhood into adolescence than those without. Children with rare CFA had 3-4 times as many potentially preventable hospitalizations until 18 years of age than those without. Specifically, respiratory infections (IRR 2.13-2.35), ear infections (IRR 7.92-26.28), and oral health-related conditions contributed for most noncraniofacial admissions until the adolescence period. A greater incidence of noncraniofacial related hospitalizations was observed among Indigenous children, births with intrauterine growth restrictions, and families with high socioeconomic disadvantage. CONCLUSIONS: Throughout childhood, individuals with rare CFA had greater hospital service use, specifically for potentially preventable conditions, than those without. These population-level findings can inform new preventive strategies and early disease management targeted toward reducing preventable hospitalizations.

Short-term air pollution exposure and hospital admissions for cardiorespiratory diseases in Brazil: A nationwide time-series study between 2008 and 2018.

The established evidence associating air pollution with health is limited to populations from specific regions. Further large-scale studies in several regions worldwide are needed to support the literature to date and encourage national governments to act. Brazil is an example of these regions where little research has been performed on a large scale. To address this gap, we conducted a study looking at the relationship between daily PM2.5, NO2, and O3, and hospital admissions for circulatory and respiratory diseases across Brazil between 2008 and 2018. A time-series analytic approach was applied with a distributed lag modeling framework. We used a generalized conditional quasi-Poisson regression model to estimate relative risks (RRs) of the association of each air pollutant with the hospitalization for circulatory and respiratory diseases by sex, age group, and Brazilian regions. Our study population includes 23, 791, 093 hospital admissions for cardiorespiratory diseases in Brazil between 2008 and 2018. Among those, 53.1% are respiratory diseases, and 46.9% are circulatory diseases. Our findings suggest significant associations of ambient air pollution (PM2.5, NO2, and O3) with respiratory and circulatory hospital admissions in Brazil. The national meta-analysis for the whole population showed that for every increase of PM2.5 by 10 µg/m3, there is a 3.28% (95%CI: 2.61; 3.94) increase in the risk of hospital admission for respiratory diseases. For O3, we found positive associations only for some sub-group analyses by age and sex. For NO2, our findings suggest that a 10 ppb increase in this pollutant, there was a 35.26% (95%CI: 24.07; 46.44) increase in the risk of hospital admission for respiratory diseases. This study may better support policymakers to improve the air quality and public health in Brazil.

Comportamiento de características seleccionadas en pacientes hospitalizados por neumonía adquirida en la comunidad y algunas asociaciones de interés práctico / Behavior of selected characteristics in patients hospitalized for community-acquired pneumonia and some associations of practical interest

La neumonía adquirida en la comunidad constituye una de las afecciones respiratorias que provoca más demanda de asistencia médica, y es responsable del mayor número de fallecidos por enfermedades infecciosas en Cuba. El objetivo del estudio ha sido determinar el comportamiento de características seleccionadas en pacientes hospitalizados por neumonía y precisar la existencia de asociaciones entre algunas de estas características.Se realizó un estudio observacional, con diseño descriptivo, que incluyó 1,809 pacientes hospitalizados por neumonía entre enero de 2012 y febrero de 2020. Fueron analizadas características relacionadas con las condiciones de base, clínico-radiológicas, y relativas al manejo y la evolución, mediante análisis bivariante y multivariante (regresión logística). La serie estuvo constituida fundamentalmente por pacientes ancianos (79%), mientras que el 20% presentaba la condición de encamamiento. Esta condición se asoció significativamente con el estado de demencia avanzada (OR 7,6[5,5;10,4]), y fue determinante en la presentación "solapada" del proceso (OR 1,5[1,09;2]). La presentación "solapada" de la neumonía estuvo significativamente asociada al ingreso tardío (OR 1,6[1,2;2,2]). Como conclusiones se ratifica el lugar que ocupan varios elementos en las características de la morbilidad por neumonía: edad avanzada, presencia de comorbilidades, y presentación no clásica del proceso. Fueron constatadas interrelaciones de importancia práctica entre la presencia de comorbilidades particulares, las formas clínicas de presentación, el momento del ingreso, y la utilización de antimicrobianos durante la atención prehospitalaria del paciente. Se destaca el papel del encamamiento en la extensión radiológica del proceso neumónico y en la presencia de derrame pleural de mediana o gran cuantía al momento del ingreso.

Community-acquired pneumonia is one of the respiratory conditions that causes the greatest demand for medical care, and is responsible for the largest number of deaths from infectious diseases in Cuba. The objective of the study was to determine the behavior of selected characteristics in patients hospitalized for pneumonia and to specify the existence of associations between some of these characteristics. An observational study, with a descriptive design, was carried out, which included 1,809 patients hospitalized for pneumonia between January 2012 and February 2020. Characteristics related to the basic, clinical-radiological conditions, and relative to management and evolution were analyzed, through analysis bivariate and multivariate (logistic regression). The series consisted mainly of elderly patients (79%), while 20% were bedridden. This condition was significantly associated with the state of advanced dementia (OR 7.6[5.5;10.4]) and was decisive in the "overlapping" presentation of the process (OR 1.5[1.09;2]). The "overlapping" presentation of pneumonia was significantly associated with late admission (OR 1.6[1.2;2.2]). As conclusions, the place occupied by several elements in the characteristics of pneumonia morbidity is ratified: advanced age, presence of comorbidities, and non-classical presentation of the process. Interrelationships of practical importance were found between the presence of comorbidities, the clinical forms of presentation, the time of admission, and the use of antimicrobials during the patient's prehospital care. The role of bed rest in the radiological extension of the pneumonic process and in the presence of medium or large pleural effusion at the time of admission is highlighted.

Prediction of heart failure decompensations using artificial intelligence and machine learning techniques / Predicción de las descompensaciones de la insuficiencia cardíaca mediante técnicas de inteligencia artificial y aprendizaje automático

Abstract Introduction: Heart failure (HF) is a major concern in public health. We have used artificial intelligence to analyze information and improve patient outcomes. Method: An Observational, retrospective, and non-randomized study with patients enrolled in our telemonitoring program (May 2014-February 2018). We collected patients’ clinical data, telemonitoring transmissions, and HF decompensations. Results: A total of 240 patients were enrolled with a follow-up of 13.44 ± 8.65 months. During this interval, 527 HF decompensations in 148 different patients were detected. Significant weight increases, desaturation below 90% and perception of clinical worsening are good predictors of HF decompensation. We have built a predictive model applying machine learning (ML) techniques, obtaining the best results with the combination of "Weight + Ankle + well-being plus alerts of systolic and diastolic blood pressure, oxygen saturation, and heart rate." Conclusions: ML techniques are useful tools for the analysis of HF datasets and the creation of predictive models that improve the accuracy of the actual remote patient telemonitoring programs.

Resumen Introducción: La insuficiencia cardíaca (IC) es un motivo de gran preocupación en la salud pública. Hemos utilizado técnicas de aprendizaje automático para analizar información y mejorar los resultados. Métodos: Estudio observacional, retrospectivo y no aleatorizado, con los pacientes incluidos en el programa de telemonitorización de IC de nuestro centro desde mayo 2014 hasta febrero 2018. Se han analizado datos clínicos, transmisiones de telemonitorización y descompensaciones de IC. Resultados: 240 pacientes incluidos con un seguimiento de 13.44 ± 8.65 meses. En este intervalo se han detectado 527 descompensaciones de IC en 148 pacientes diferentes. Los aumentos significativos de peso, la desaturación inferior al 90% y la percepción de empeoramiento clínico, han resultado buenos predictores de la descompensación de IC. Hemos construido un modelo predictivo aplicando técnicas de aprendizaje automático obteniendo los mejores resultados con la combinación de "Peso + Edemas en EEII + empeoramiento clínico + alertas de tensión arterial sistólica y diastólica, saturación de oxígeno y frecuencia cardiaca". Conclusiones: Las técnicas de inteligencia artificial son herramientas útiles para el análisis de las bases de datos de IC y para la creación de modelos predictivos que mejoran la precisión de los programas de telemonitorización actuales.

Behavior of clinical and humoral variables on admission as predictors of death in patients with community-acquired pneumonia. Comparative study between adults and older adults. / Comportamiento de variables clínicas y humorales al ingreso, como predictores de fallecimiento en pacientes con neumonía adquirida en la comunidad. Estudio comparativo entre adultos y adultos mayores

Community-acquired pneumonia is recognized as one of the main infectious health problems worldwide. The objective was to determine the condition of predictors of death for a group of selected clinical conditions, and for laboratory variables frequently used in practice. Study with descriptive design, which included 967 patients with pneumonia hospitalized between 2016 and 2019, and whose information was obtained from clinical records. Statistical treatment included bivariate and multivariate analysis (logistic regression); it was used the ratio of crossed products (odds ratio) and its 95% confidence interval. Several manifestations were significantly more frequent in older adults: dyspnea (OR 1.5[1.07,2.1]), absence of productive cough (OR 1.7 [1.3, 2.4]), neuropsychological manifestations (OR 2 [1.4,2.8]), tachypnea (OR 1.5 [1.1,2.1]), arterial hypotension (OR 2.1 [1.2,3.6]), anemia (OR 1.6[1.2,2.2]), elevated creatinine (OR 1.6[1.2,2.3]) and hypoproteinemia (OR 3.3[1.9,5.7]); showed a significant association with death: absence of productive cough, neuropsychological manifestations, temperature below 36 degrees Celsius, blood pressure below 110/70 mmHg, respiratory rate above 20 per minute, hemoglobin below 100 g/L, erythrosedimentation greater than 20 mm/L, leukopenia less than 5 x 109/L and serum creatinine above 130 micromol/L. As conclusions certain clinical and laboratory conditions present in the patient at the time of hospital admission, of routine exploration in the comprehensive assessment of the patient, were predictors of death. Additionally, the existence of evident differences in the number of conditions with a predictive nature of death between the population with pneumonia under 60 years of age and the elderly, as well as in the frequency of these conditions in both subgroups, is verified.

La neumonía adquirida en la comunidad está reconocida como uno de los principales problemas de salud de tipo infeccioso al nivel mundial. La investigación tuvo como objetivo determinar el carácter de predictores de fallecimiento de un grupo de condiciones clínicas seleccionadas, y de variables de laboratorio de uso frecuente en la práctica. Se realizó un estudio con diseño descriptivo, que incluyó a 967 pacientes con neumonía hospitalizados entre 2016 y 2019, y cuya información se obtuvo de los expedientes clínicos. El tratamiento estadístico incluyó análisis bivariante y multivariado (regresión logística); como estadígrafo se utilizó la razón de productos cruzados (odds ratio) y su intervalo de confianza de 95%. Entre los resultados se destacan los siguientes: varias manifestaciones fueron significativamente más frecuentes en los adultos mayores: disnea (OR 1,5[1,07;2,1]), ausencia de tos productiva (OR 1,7[1,3;2,4]), manifestaciones neuropsicológicas (OR 2[1,4;2,8]), taquipnea (OR 1,5[1,1;2,1]), hipotensión arterial (OR 2,1[1,2;3,6]), anemia (OR 1,6[1,2;2,2]), creatinina elevada (OR 1,6[1,2;2,3]) e hipoproteinemia (OR 3,3[1,9;5,7]); mostraron asociación significativa con el fallecimiento: ausencia de tos productiva, manifestaciones neuropsicológicas, temperatura por debajo de 36 grados Celsius, tensión arterial inferior a 110/70 mmHg, frecuencia respiratoria por encima de 20 por minuto, hemoglobina inferior a 100 g/L, velocidad de sedimentación eritrocitaria superior a 20 mm/L, leucopenia inferior a 5 x 109/L y creatinina sérica por encima de 130 micromol/L. Se concluye que ciertas condiciones clínicas y de laboratorio presentes en el paciente al momento del ingreso hospitalario, de exploración habitual en la valoración integral del enfermo, constituyeron predictores de fallecimiento. Adicionalmente, se comprueba la existencia de evidentes diferencias en el número de condiciones con carácter predictor de muerte entre la población con neumonía menor de 60 años y los adultos mayores, así como en la frecuencia de estas condiciones en ambos subgrupos.

Ingresos pediátricos asociados a infección por SARS-CoV-2 en un prestador de salud / Pediatric admissions associated with SARS-CoV-2 infection in a health provider / Admissões pediátricas associadas à infecção por SARS-CoV-2 em um profissional de saúde

Introducción: en enero de 2020 se identificó un nuevo coronavirus como etiología de un síndrome respiratorio agudo severo, que se denominó coronavirus 2 (SARS-CoV-2). A la enfermedad asociada se conoce como enfermedad por coronavirus 2019 (COVID-19). El SARS-CoV-2 se expandió rápidamente a nivel mundial, decretándose en marzo de 2020 estado de pandemia. La población pediátrica constituyó el 1%-2% del total de casos confirmados, con una tasa de mortalidad menor al 0,2%. En concordancia con lo que sucedía a nivel internacional, se registró en Uruguay un número de ingresos hospitalarios por COVID-19 en menores de 19 años muy inferior al resto de los grupos etarios, así como un menor número de ingresos a unidades de cuidados intensivos (UCI) y de defunciones. El objetivo de esta revisión fue describir los ingresos pediátricos con infección por SARS-CoV-2 en un prestador de salud privado, de la ciudad de Montevideo. Metodología: se incluyeron todos los pacientes menores de 15 años con identificación de infección viral por COVID-19 que requirieron hospitalización en cuidados moderados en el período comprendido entre abril de 2020 a febrero de 2022. Se utilizó reacción en cadena de polimerasa y detección antigénica para COVID-19 para el diagnóstico de infección aguda. Serología para el diagnóstico de infección previa. Resultados: de los 1.164 pacientes ingresados en dicho periodo, en 2% se identificó infección por COVID-19. 80% tenían un nexo epidemiológico, 69% era intradomiciliario. 8% menor de 1 año, 69% entre 1-11 años, 23% mayores de 11 años. 27% presentaban comorbilidad: asma y encefalopatía, un 57% de ellos presentaban toracopatia concomitante. Los motivos de ingreso más frecuentes fueron síntomas respiratorios, con fiebre y lesiones en piel, patología quirúrgica, síntomas neurológicos. Dos requirieron ingreso a CTI. No se reportaron fallecimientos. La mediana de días de hospitalización fue 4 días (1-18 días). Conclusiones: si bien el porcentaje de niños ingresados con infección por SARS-CoV-2 fue pequeño la expresión clínica fue variada, mayoría presentó infección respiratoria leve. Los pacientes con comorbilidades presentaron mayor probabilidad de desarrollar enfermedad aguda moderada a grave. Se debe tener en cuenta la probabilidad de infección por SARS-CoV-2 ante la aparición de otros síntomas, en el curso de infecciones virales.

Summary: Introduction: in January 2020, a new coronavirus was identified as the etiology of a severe acute respiratory syndrome, which was called coronavirus 2 (SARS-CoV-2). The associated illness is known as coronavirus disease 2019 (COVID-19). SARS-CoV-2 spread rapidly worldwide, becoming a pandemic in March 2020. The pediatric population involved 1-2% of the total confirmed cases, with a mortality rate of less than 0.2%. In line with the global trend, children under 19 years of age showed a much lower number of hospital admissions for COVID-19 in Uruguay compared to the remaining age groups, as well as lower number of ICU admissions and deaths. The objective of this paper is to describe pediatric admissions with SARS-Cov-2 infection at a private health provider in Montevideo city. Methodology: we included all patients under 15 years of age with a diagnosis of viral infection by Covid-19 who required hospitalization in moderate care, between 04/20 and 02/22. We used polymerase chain reaction and antigen detection for Covid-19 for the diagnosis of acute infections and serology tests for the diagnosis of a previous infection. Results: of the 1,164 patients admitted in that period, 2% were diagnosed with Covid 19 infection. 80% had an epidemiological link, 69% had home infections. 8% under 1 year of age, 69% between 1-11, 23% over 11 years of age. 27% had comorbidities: asthma and encephalopathy, 57% of them had concomitant thorax pathologies. The most frequent reasons for admission were respiratory symptoms, with fever and skin lesions, surgical pathologies, and neurological symptoms. 2 required ICU admission. No deaths were reported. The median number hospitalization days was 4 days (1-18 days). Conclusions: although the percentage of children admitted with SARS-CoV-2 infections was low, the clinical manifestation was varied, most presented mild respiratory infections. Patients with comorbidities were more likely to develop moderate to severe acute illness. The probability of SARS-CoV-2 infection should be taken into account when other symptoms appear during the course of viral infections.

Introdução: em janeiro de 2020, um novo coronavírus foi identificado como a etiologia de uma síndrome respiratória aguda grave, que recebeu o nome de coronavírus 2 (SARS-CoV-2). A doença associada é conhecida como doença de coronavírus 2019 (COVID-19). O SARS-CoV-2 se espalhou rapidamente em todo o mundo, e virou-se pandemia em março de 2020. A população pediátrica constituiu 1-2% do total de casos confirmados, com uma taxa de mortalidade inferior a 0,2%. De acordo com as tendencias globais, registrou-se no Uruguai um número muito menor de internações por COVID-19 em menores de 19 anos do que no restante das faixas etárias, bem como um número menor de internações em unidades de terapia intensiva (UTI) e óbitos. O objetivo deste estudo é descrever as internações pediátricas com infecção por SARS-Cov-2 numa Assistência Privada de saúde na cidade de Montevidéu. Metodologia: foram incluídos todos os pacientes menores de 15 anos com diagnóstico de infecção viral por Covid-19 que necessitaram de internação em cuidados moderados, entre 20/04 a 22/02. Utilizou-se a reação em cadeia da polimerase e a detecção de antígeno para Covid-19 para o diagnóstico de infecção aguda e estudo sorológico para o diagnóstico de infecção prévia. Resultados: dos 1.164 pacientes internados nesse período, 2% foram diagnosticados com infecção por Covid 19. 80% tinham vínculo epidemiológico, 69% tiveram infecção domiciliar. 8% tinham menos de 1 ano de idade, 69% entre 1-11, 23% com mais de 11 anos. 27% tinham comorbidades: asma e encefalopatia, 57% deles tinham patologias torácicas concomitantes. Os motivos de admissão mais frequentes foram sintomas respiratórios com febre e lesões cutâneas, patologias cirúrgicas e sintomas neurológicos. 2 necessitaram de internação na UTI. Nenhuma morte foi relatada. A mediana do número de dias de internação foi de 4 dias (1-18 dias). Conclusões: embora a porcentagem de crianças admitidas com infecção por SARS-CoV-2 fosse baixa, a manifestação clínica foi variada, a maioria apresentou infecção respiratória leve. Pacientes com comorbidades foram mais propensos a desenvolver doença aguda moderada a grave. A probabilidade de infecção por SARS-CoV-2 deve ser levada em consideração quando outros sintomas aparecem no curso de infecções virais.

Air pollution epidemiology: A simplified Generalized Linear Model approach optimized by bio-inspired metaheuristics.

Studies in air pollution epidemiology are of paramount importance in diagnosing and improve life quality. To explore new methods or modify existing ones is critical to obtain better results. Most air pollution epidemiology studies use the Generalized Linear Model, especially the default version of R, Splus, SAS, and Stata softwares, which use maximum likelihood estimators in parameter optimization. Also, a smooth time function (usually spline) is generally used as a pre-processing step to consider seasonal and long-term tendencies. This investigation introduces a new approach to GLM, proposing the estimation of the free coefficients through bio-inspired metaheuristics - Particle Swarm Optimization (PSO), Genetic Algorithms, and Differential Evolution, as well as the replacement of the spline function by a simple normalization procedure. The considered case studies comprise three important cities of São Paulo state, Brazil with distinct characteristics: São Paulo, Campinas, and Cubatão. We considered the impact of particles with an aerodynamic diameter less than 10 µm (PM10), ambient temperature, and relative humidity in the number of hospital admissions for respiratory diseases (ICD-10, J00 to J99). The results showed that the new approach (especially PSO) brings performance gains compared to the default version of statistical software like R.

Avaliação da satisfação de pacientes oncológicos com o serviço de saúde em um hospital público no Brasil / Evaluation of oncology patients satisfaction with health service in a public hospital in Brazil

Resumo Introdução A satisfação dos pacientes é fundamental para melhorar a qualidade dos serviços. Para uniformizar as pesquisas foi criado o EORTC-IN-PATSAT32. Objetivo O objetivo foi avaliar a satisfação dos pacientes com a internação. Método Foram entrevistados 322 pacientes, através dos questionários socioeconômico e EORTC-IN-PATSAT32. Os itens múltiplos foram agrupados nas dimensões previstas na versão brasileira do questionário. Foram utilizados testes de hipóteses para avaliar diferenças na avaliação. Resultados A maioria dos pacientes era do sexo masculino, maiores de 60 anos, baixa escolaridade, casados, em atendimento clínico e sem metástase. Maior nível de satisfação foi com alta hospitalar e maior insatisfação com a estrutura. Houve maior satisfação com a equipe multiprofissional entre os pacientes com menor escolaridade e mais de 40 anos. Os pacientes cirúrgicos e brancos tiveram a maior satisfação com os médicos. Pacientes casados foram os mais satisfeitos com a conduta terapêutica, enquanto homens e idosos foram os mais satisfeitos com a estrutura, e os brancos mais satisfeitos com a alta. Conclusão Sexo, faixa etária, raça, grau de escolaridade, estado civil e modalidade de tratamento influenciam a satisfação dos pacientes. Recomenda-se o desenvolvimento de estudos em outros hospitais do país para relacionar a satisfação com as características da população brasileira.

Abstract Background Patient satisfaction is fundamental to improve the quality of health services. In order to standardize the surveys, the EORTC-IN-PATSAT32 questionnaire was created. Objective The objective was to evaluate patients' satisfaction with hospitalization. Method 322 patients were interviewed through the socioeconomic aspects and EORTC-IN-PATSAT32 questionnaires. The multiple items were grouped in the dimensions provided for in the Brazilian version of the questionnaire. Hypothesis tests were used to evaluate differences in the evaluation. Results The majority of the patients were male, older than 60 years, low educational level, married, in clinical care and without metastasis. Higher level of satisfaction was with hospital discharge and greater dissatisfaction with the structure. There was greater satisfaction with the multi-professional team among patients with less education and more than 40 years. Surgical and white patients had the greatest satisfaction with physicians. Married patients were the most satisfied with the therapeutic conduct, while men and elderly were the most satisfied with the structure, as long as whites were more satisfied with the discharge. Conclusion Patient satisfaction is influenced by gender, age, race, education level, marital status and treatment modality. It is recommended the development of studies in other hospitals in the country to relate the satisfaction with the characteristics of the Brazilian population.

Subsidizing access to prescription drugs and health outcomes: The case of diabetes.

This paper evaluates the health effects of a large-scale subsidizing program of prescription drugs introduced in Brazil, the Aqui Tem Farmácia Popular program (ATFP). We exploit features of the program to identify its effects on mortality and hospitalization rates by diabetes for individuals aged 40 years or more. We find weak evidence for a decline in mortality, but a robust reduction in hospitalization rates. According to our preferred specification, an additional ATFP pharmacy per 100,000 inhabitants is associated with a decrease in hospitalization rates by diabetes of 8.2, which corresponds to 3.6% of its baseline rate. Effects are larger for Type II diabetes in comparison to Type I, and among patients with relatively lower socioeconomic status. Overall, the results are consistent with insulin-dependent patients being relatively less responsive to subsidies because of higher immediate life-threatening risks; and with lower-SES individuals being more responsive because of liquidity constraints. These results support the view that the optimal design of health systems and cost-sharing mechanisms should take into account equity concerns, heterogeneous impacts by health condition, and their potential offsetting effects on the utilization of downstream health services.

Epidemiological profile of alcoholic liver disease hospital admissions in a Latin American country over a 10-year period.

BACKGROUND: Alcoholic liver disease (ALD) is a major cause of chronic liver disease worldwide. AIM: To describe the epidemiological profile and mortality rates of patients with ALD admitted to public hospitals in different regions of Brazil from 2006 to 2015. METHODS: This is a descriptive study that evaluated aggregate data from the five Brazilian geographic regions. RESULTS: A total of 160093 public hospitalizations for ALD were registered. There was a 34.07% increase in the total number of admissions over 10 years, from 12879 in 2006 to 17267 in 2015. The region with the highest proportion (49.01%) of ALD hospitalizations was Southeast (n = 78463). The North region had the lowest absolute number of patients throughout the study period, corresponding to 3.9% of the total (n = 6242). There was a 24.72% increase in the total number of ALD deaths between 2006 and 2015. We found that the age group between 50 and 59 years had the highest proportion of both hospitalizations and deaths: 28.94% (n = 46329) of total hospital admissions and 29.43% (n = 28864) of all deaths. Men were more frequently hospitalized than women and had the highest proportions of deaths in all regions. Mortality coefficient rates increased over the years, and simple linear regression analysis indicated a statistically significant upward trend in this mortality (R² = 0.744). CONCLUSION: Our study provides a landscape of the epidemiological profile of public hospital admissions due to ALD in Brazil. We detected an increase in the total number of admissions and deaths due to ALD over 10 years.

Relação entre a cobertura de atenção básica das capitais do Nordeste e taxas de internações por causas sensíveis à saúde / Relatioship between primary care coverage of northeaste capitals and health-sensitive hospitalizatioon rates

Introdução: as Doenças Crônicas Não Transmissíveis (DCNTs) correspondem a um grave problema de saúde pública e representam um empecilho frente ao desenvolvimento humano. Objetivou-se apresentar a distribuição da cobertura da atenção da básica no período de 2004 a 2009 e descrever as taxas de internações para causas sensíveis em saúde e doenças hipertensivas nas capitais dos estados da região Nordeste do Brasil. Metodologia: realizou-se estudo ecológico, a partir de dados secundários disponíveis no Departamento de Informática do Sistema Único de Saúde (DATASUS) e do Sistema de Informações Hospitalares do SUS (SIHSUS). Os dados foram exportados dos sistemas de informação e posteriormente foram obtidas as medidas de frequências relativas. Os dados foram tabulados e apresentados em formato de gráficos. Resultados: os resultados sobre a distribuição da cobertura de atenção básica revelaram que Aracaju e Teresina são as capitais com maior cobertura (95,3% e 90,0%, respectivamente); nas taxas de internações sensíveis à atenção básica, João Pessoa e Teresina aparecem com as maiores taxas, 147,2 e 155,2, respectivamente, no ano de 2005; no que se relaciona às taxas de internações por doenças hipertensivas, Teresina foi a capital com as maiores taxas de 2004 a 2009 (15,5% e 12,3%, respectivamente), mesmo com a diminuição ocorrida a partir de 2006. Conclusão: de acordo com os resultados encontrados as capitais que apresentavam maior cobertura de atenção básica, são aquelas que apresentaram as maiores taxas de internações por causas sensíveis. Como a análise foi descritiva, não foi possível mensurar a associação entre os eventos, nem questões relacionadas à qualidade e efetividade da atenção prestada. Dessa forma, sugere-se que sejam realizados estudos analíticos sobre a avaliação da efetividade da atenção básica no Nordeste.

Introduction: uncommunicable Chronic Diseases (DCNT, for its acronym in Portuguese) constitutes a serious public health problem and represents an obstacle to the human development. The objective was to present paper the distribution of coverage of primary care and describe hospital admission rate for sensitive health conditions and hypertensive diseases and primary care coverage in capital states of North-eastern Brazil during the period of 2004-2009. Methodology: an ecological study was conducted from the information available in the Department of Informatics of the Unified Health System (DATASUS, for its acronym in Portuguese) and Hospitals Information System of Unified Health System (SIHSUS, for its acronym in Portuguese) databases. The data were exportedfrom the information systems and subsequently the relative frequency measurements were obtained. The data was formatted and presented in graphs. Results: the results on the distribution of primary care, revealed that Aracaju and Teresina are the cities with the highest coverage (95.3% and 90.0%, respectively). Regarding the primary care admission rates during the year of 2005, João Pessoa and Teresina stand out with the highest rates, 147,2 and 155,2 respectively. When it comes to admissions rates for hypertensive diseases, Teresina was the capital with highest rates from 2004 to 2009 (15.5% and 12.3%, respectively), despite the decreasing since 2006. Conclusion: according to the results founded, the capitals that had the highest coverage of primary care are those which had the highest rates of hospitalizations for sensitive causes. As the analysis was descriptive, it was not possible to measure the association between the events, nor questions related to the quality and effectiveness of the care provided. Thus, it is suggested that analytical studies be carried out on the evaluation of the effectiveness of primary care in the northeast of the country.

Trends in air quality and hospital admissions due to respiratory diseases since the standstill of an industrial plant in Brazil.

At the end of 2015, the rupture of an iron ore tailings dam resulted in the standstill of a pelletizing plant in the city of Anchieta, southeastern Brazil. Despite the negative environmental impact due to the dam rupture, the pelletizing plant standstill has provided a valuable opportunity for the assessment of the changes in local air quality. This work presents a statistical analysis of the spatial and temporal patterns of PM10, PM2.5, SO2, NO2, and O3, between 2012 and 2018, aiming to identify the trends in the air quality since the pelletizing plant standstill. This work also shows the analysis of the short-term and long-term exposures and the exceedances of the local air quality standards (AQS), as well as the study of the directional patterns of the pollutants associated with the prevailing winds. Since 2016, a meaningful improvement in the air quality of Anchieta was observed, coinciding with the pelletizing plant standstill. Since then, PM10 annual averages have decreased between 10 and 30%, while SO2 annual averages have decreased between 38 and 64%, depending on the monitoring station, which has led to a significant reduction in the exceedances of the AQS thresholds for these pollutants. Besides, the results suggest, qualitatively, a strong influence of the industrial emissions on the health of the Anchieta's population. The restart of the pelletizing plant production is expected in 2020; nevertheless, the results suggest the need for major improvements in the pollution control systems of the pelletizing plant before its resumption.

Provision of inhaled corticosteroids is associated with decrease in hospital admissions in Brazil: A longitudinal nationwide study.

OBJECTIVE: To describe trends of hospital admissions due to asthma from 2008 to 2015 and to evaluate their relationship with trends of inhaled corticosteroids (ICS) provision by the government in Brazil. METHODS: We used Brazilian Government data to calculate hospital admission rates due to asthma, number of physicians, number of hospital beds, number of subjects that received ICS per 100,000 inhabitants in Brazil and in each of its municipalities for each year of the study. We performed Poisson Multilevel Regression Analyses to evaluate the relationship between the trends of hospital admission rates due to asthma with the trends of the number of subjects that had been receiving ICS during the study period. The analyses were adjusted for the number of physicians and hospital beds. FINDINGS: The number of patients who received ICS/100,000 inhabitants increased from 2008 to 2015 (943.9-1988.5). Hospital admissions/100,000 inhabitants decreased in patients aged 5-14 years (148.3-110.9) and in patients aged 15-39 years (59.9-32.3); the reduction was greater in municipalities in which ICS provision increased. The number of physicians/100,000 inhabitants increased and the number of hospital beds/100,000 inhabitants decreased in the study period. The increase in the number of physicians and in the number of subjects that received ICS were associated with reduction in hospital admissions. CONCLUSION: We found that provision of ICS by the Brazilian Government was associated with a decrease of hospital admissions for asthma in the municipalities and country levels from 2008 to 2015.

Key factors associated with uncontrolled asthma - the Asthma Control in Latin America Study.

Objective: This study aimed to estimate asthma control at specialist treatment centers in four Latin American countries and assess factors influencing poor asthma control.Methods: Patients aged ≥12 years with an asthma diagnosis and asthma medication prescription, followed at outpatient specialist centers in Argentina, Chile, Colombia, and Mexico, were included. The study received all applicable ethical approvals. The Asthma Control Test (ACT) was used to classify patients as having controlled (ACT 20-25) or uncontrolled (ACT ≤19) asthma. Frequency and statistical tests were used to assess the association between hospital admissions/exacerbations/emergency department (ED) visits and uncontrolled asthma; multivariate logistic regression was used to assess the association of uncontrolled asthma with clinical/demographic variables.Results: A total of 594 patients were included. Overall controlled-asthma prevalence was 43.4% (95% confidence interval [CI]: 39.0, 47.4). Patients with uncontrolled asthma were more likely to be women (adjusted odds ratio [aOR]: 1.85; p = 0.003), non-white (aOR: 2.14; p < 0.001), obese (aOR: 1.71; p = 0.036), to have a low monthly family income (aOR: 1.75; p = 0.004), to have severe asthma (aOR:1.59; p = 0.26), and, compared with patients with controlled asthma, to have a higher likelihood of asthma exacerbations (34.5% vs. 15.9%; p < 0.001), hospital admissions (6.9% vs. 3.1%; p = 0.042), and ED visits (34.5% vs. 15.9%; p < 0.001) due to asthma.Conclusions: Even in specialist ambulatory services, fewer than half of patients were classified as having controlled asthma. The proportion of uncontrolled patients varied according to clinical and demographic variables.

Regional drinking water composition effects on hip fracture risk: a spatial analysis of nationwide hospital admissions in Portugal, from 2000 to 2010 / Efeitos da composição regional da água potável no risco de fratura do fêmur: uma análise espacial das admissões hospitalares em Portugal, de 2000 a 2010

Abstract Geographical variation on hip fractures (HF) may be related to the geographical variation of drinking water composition (DWC); minerals in drinking water may contribute to its fragility. We aim to investigate the effects of DWC on HF risk in Portugal (2000-2010). From National Hospital Discharge Register we selected admissions of patients aged ≥50 years, diagnosed with HF caused by low/moderate energy traumas. Water components and characteristics were selected at the municipality level. A spatial generalized additive model with a negative binomial distribution as a link function was used to estimate the association of HF with variations in DWC. There were 96,905HF (77.3% in women). The spatial pattern of HF risk was attenuated after being adjusted for water parameters. Results show an indirect association between calcium, magnesium, and iron and HF risk but no clear relation between aluminum, cadmium, fluoride, manganese, or color and HF risk. Regarding pH, the 6.7pH and 7pH interval seems to pose a lower risk. Different dose-response relationships were identified. The increase of calcium, magnesium, and iron values in DWC seems to reduce regional HF risk. Long-term exposure to water parameters, even within the regulatory limits, might increase the regional HF risk.

Resumo A variabilidade espacial existente na fratura do colo do fêmur (FCF) pode estar relacionada com a variabilidade geográfica da composição da água para consumo (CAC), devido à ação dos minerais na fragilidade óssea. O objetivo do artigo foi investigar o efeito da CAC no risco de FCF em Portugal (2000-2010). Do registo nacional de altas hospitalares, foram selecionadas todas as admissões em indivíduos ≥50, com diagnóstico de FCF causado por trauma de baixo/moderado impacto. Os componentes e características da água foram usados ao nível do município. Um modelo espacial aditivo generalizado, com a distribuição binomial negativa como função de ligação, foi usado para estimar a associação de FCF e as variações da CAC. Foram selecionadas 96.905 FCF (77,3% em mulheres). O padrão espacial de risco de FCF foi atenuado após ser ajustado pelos parâmetros da CAC. Os resultados mostraram uma associação indireta com cálcio, magnésio e ferro. No entanto, com alumínio, cádmio, fluoreto, manganês e cor, a associação com o risco não foi clara. O intervalo de pH de 6,7 a 7 parece apresentar um menor risco. Foram identificadas diferentes dose-resposta. O aumento do cálcio, magnésio e ferro na CAC parece reduzir o risco regional de FCF. Uma exposição a longo prazo, mesmo obedecendo aos limites impostos por lei, parece aumentar o risco regional de FCF.

Influência do clima nas hospitalizações por asma em crianças e adolescentes residentes em Belo Horizonte, Minas Gerais, Brasil / The influence of climatic conditions on hospital admissions for asthma in children and adolescents living in Belo Horizonte, Minas Gerais, Brazil

Resumo O risco de hospitalização por asma influenciado pelo disparo das condições climáticas é pouco explorado em Minas Gerais. Os objetivos deste artigo são: a) avaliar a influência dos fatores climáticos nas hospitalizações por asma e por infecções virais do trato respiratório inferior (IVTRI), de 2002 a 2012, em crianças e adolescentes residentes em Belo Horizonte (BH) e estimar períodos epidêmicos para as hospitalizações por asma; b) comparar o padrão sazonal local das hospitalizações por asma e IVTRI. Utilizando as hospitalizações por asma estratificadas e por bronquiolite de 0-4 anos, a partir das guias de Internação Hospitalar, modelos estatísticos de regressão foram aplicados para avaliar o relacionamento entre as variáveis. Para estimar períodos epidêmicos foi utilizado o modelo de séries temporais da classe ARIMA. Foi observado um incremento nas hospitalizações por asma com aumento da umidade relativa no período pós-chuvas, as hospitalizações por bronquiolite se associaram a baixos níveis de temperatura máxima e precipitação. Períodos mais chuvosos podem propiciar o aumento da umidade outdoor e indoor favorecendo proliferação fúngica. Já os períodos mais frios podem favorecer o aumento da disseminação de vírus.

Abstract Limited research exists on the influence of climatic conditions on the risk of hospital admission for asthma in Minas Gerais, Brazil. The objectives of this article are: a) to evaluate the influence of climatic conditions on hospital admissions for asthma and lower respiratory tract infections (LRTIs) among children and adolescents living in Belo Horizonte during the period 2002 to 2012 and identify epidemic peaks of admissions for asthma; b) to compare local seasonal patterns of admissions for asthma and LRTIs. Using hospital admission data stratified by aged group, regression analysis was performed to determine the relationship between the variables. Epidemic peaks were identified using an ARIMA model. There was an increase in admissions for asthma with an increase in relative humidity after rainy periods; admissions for bronchiolitis were associated with low levels of maximum temperature and rainfall. Rainy periods can lead to an increase in indoor and outdoor humidity, facilitating fungal proliferation, while cold periods can lead to an increase in the spread of viruses.

[Direct medical costs of hospitalization due to heart failure in the health plan of the Hospital Italiano de Buenos Aires.] / Costos médicos directos de las Internaciones por Insuficiencia Cardiaca en el Plan de Salud del Hospital Italiano de Buenos Aires.

Introduction: It is undeniable that costs of medical care in chronic diseases has increased. There are multiple reasons: population aging, associated pathologies late complications, available high cost health technologies. Heart failure is one of the main causes of global death and morbidity, being the final consequence of cardiac diseases and hypertension, fulfilling criteria of becoming a high costs pathology. We are going to evaluate direct medical costs of hospitalization due to heart failure from the vision of those who manage health resources. Materials and Methods: Observational, retrospective cohort using secondary databases from the Hospital Italiano de Buenos Aires. Adult population with diagnosed heart failure that required hospitalization with discharge diagnosis of heart failure between 2007 and 2011. Results: The main cost component was attributable to hospital bed, diagnostic and therapeutic interventions. The average incidence of hospitalizations during the period was 11.4 per 10,000 patients / year. Overall mortality in the episode rate was 0.25% per year and 28.8 % overall 60% Conclusion: The most important decision seems decide whether management can be done on an outpatient basis or not, using heart failures guidelines to optimize time of admission, auxiliary diagnostic methods and medications used.
