Internal validity of the Swedish Maternal Health Care Register

Background: The Swedish Maternal Health Care Register (MHCR) is a national quality register that has been collecting pregnancy, delivery, and postpartum data since 1999. A substantial revision of the MHCR resulted in a Web-based version of the register in 2010. Although MHCR provides data for health care services and research, the validity of the MHCR data has not been evaluated. This study investigated degree of coverage and internal validity of specific variables in the MHCR and identified possible systematic errors. Methods: This cross-sectional observational study compared pregnancy and delivery data in medical records with corresponding data in the MHCR. The medical record was considered the gold standard. The medical records from nine Swedish hospitals were selected for data extraction. This study compared data from 878 women registered in both medical records and in the MHCR. To evaluate the quality of the initial data extraction, a second data extraction of 150 medical records was performed. Statistical analyses were performed for degree of coverage, agreement and correlation of data, and sensitivity and specificity. Results: Degree of coverage of specified variables in the MHCR varied from 90.0% to 100%. Identical information in both medical records and the MHCR ranged from 71.4% to 99.7%. For more than half of the investigated variables, 95% or more of the information was identical. Sensitivity and specificity were analysed for binary variables. Probable systematic errors were identified for two variables. Conclusions: When comparing data from medical records and data registered in the MHCR, most variables in the MHCR demonstrated good to very good degree of coverage, agreement, and internal validity. Hence, data from the MHCR may be regarded as reliable for research as well as for evaluating, planning, and decision-making with respect to Swedish maternal health care services.

The Adequacy of Health Care Services for the Elderly in China

This study examines the adequacy of health care services for the elderly in China, specifically focusing on the influence of location, method of payment, living situation, and financial status. The study finds that rural residents, respondents living alone and respondents unable to meet all of their daily costs have a lower probability of reporting the availability of adequate health care. It also investigates the reasons why elderly respondents do not visit the hospital when it is necessary, concluding that financial and distance constraints are main deterrents. Finally, changes in the reported adequacy of health care over time are taken into consideration, and are found to follow a likely pattern given the history of the health care system in China. This is an important investigation given the historical background of health care in China, the current cost problems facing residents, and, consequently, the policy changes that will need to be implemented by the Chinese government in the near future.

Rawls and Health Care

John Rawls’s A Theory of Justice (1971), his first major work articulating his theory of justice as fairness, was immediately recognized as a fundamental contribution to political philosophy in the twentieth century. Working within the tradition established by previous philosophers such as Kant and Locke, Rawls employed the contract theory approach. Taking it to a higher order of abstraction, he sought to determine not what the structure of social organization would be, but what the principles which governed social institutions would be under a hypothetical contracting situation. Rawls uses this contract theory approach to construct a society in which the morally irrelevant contingencies of nature and social arrangements are mitigated by principles of justice which govern the basic institutions of society. A common observation has been that Rawls left out any discussion of health care and how it might fit into his conception of a just society. Several philosophers have articulated expansions of the theory to account for health care. In the chapters that follow I will continue this tradition and consider how justice as fairness might be expanded to account for just health care allocation. In doing so, I hope to answer a particularly strong critique of the theory brought up by Amartya Sen and Martha Nussbaum, and to argue for a broadened conception of health care which takes into account the complex causal relationship between society and human health.

Análise dos fundamentos do modelo value-based health care delivery à luz das teorias de estratégia

O setor de saúde, globalmente, apresenta problemas relacionados aos seus custos, qualidade e acesso. Porter e Teisberg (2004, 2006) propuseram modelo de gestão específico para a administração estratégica na área, o Value-Based Health Care Delivery (VBHCD). O modelo teve relativa repercussão e vem influenciando muitos atores no setor. Contudo, o modelo vem sendo aceito sem o devido questionamento de seus fundamentos e consistência com a teoria em estratégia. O presente trabalho busca, por meio de um ensaio teórico, analisar o modelo proposto à luz de paradigmas gerais da estratégia empresarial como, por exemplo, o modelo de Porter e a Visão Baseada em Recursos (RBV). Inicialmente, o artigo sintetiza as explicações teóricas do modelo porteriano clássico e da RBV. Em seguida, o VBHCD é examinado comparado a essas explicações, buscando-se relações e, eventualmente, contradições. Conclui-se que o modelo VBHCD não se alinha integralmente a nenhum corpo teórico isoladamente. Mesmo sendo proposto por Porter, parte de seus fundamentos advém, na verdade, de outras correntes teóricas. Esta abordagem integradora de teorias concorrentes, apesar de presente na literatura, ainda apresenta dificuldades e barreiras, um aspecto que não está explícito no modelo

Essays on health care reform, wealth inequality, and demography

This thesis contains three chapters. The first chapter uses a general equilibrium framework to simulate and compare the long run effects of the Patient Protection and Affordable Care Act (PPACA) and of health care costs reduction policies on macroeconomic variables, government budget, and welfare of individuals. We found that all policies were able to reduce uninsured population, with the PPACA being more effective than cost reductions. The PPACA increased public deficit mainly due to the Medicaid expansion, forcing tax hikes. On the other hand, cost reductions alleviated the fiscal burden of public insurance, reducing public deficit and taxes. Regarding welfare effects, the PPACA as a whole and cost reductions are welfare improving. High welfare gains would be achieved if the U.S. medical costs followed the same trend of OECD countries. Besides, feasible cost reductions are more welfare improving than most of the PPACA components, proving to be a good alternative. The second chapter documents that life cycle general equilibrium models with heterogeneous agents have a very hard time reproducing the American wealth distribution. A common assumption made in this literature is that all young adults enter the economy with no initial assets. In this chapter, we relax this assumption – not supported by the data – and evaluate the ability of an otherwise standard life cycle model to account for the U.S. wealth inequality. The new feature of the model is that agents enter the economy with assets drawn from an initial distribution of assets. We found that heterogeneity with respect to initial wealth is key for this class of models to replicate the data. According to our results, American inequality can be explained almost entirely by the fact that some individuals are lucky enough to be born into wealth, while others are born with few or no assets. The third chapter documents that a common assumption adopted in life cycle general equilibrium models is that the population is stable at steady state, that is, its relative age distribution becomes constant over time. An open question is whether the demographic assumptions commonly adopted in these models in fact imply that the population becomes stable. In this chapter we prove the existence of a stable population in a demographic environment where both the age-specific mortality rates and the population growth rate are constant over time, the setup commonly adopted in life cycle general equilibrium models. Hence, the stability of the population do not need to be taken as assumption in these models.

Quality of life and its association with cardiovascular risk factors in a community health care program population

OBJECTIVE: To evaluate quality of life in a population that attended a specific community event on health care education, and to investigate the association of their quality of life with the presence of cardiovascular risk factors INTRODUCTION: Interest in health-related quality of life is growing worldwide as a consequence of increasing rates of chronic disease. However, little is known about the association between quality of life and cardiovascular risk factors. METHODS: This study included 332 individuals. Demographics, blood pressure, body mass index, and casual glycemia were evaluated. The brief version of the World Health Organization Quality of Life questionnaire on quality of life was given to them. The medians of the scores obtained for the physical, psychological, emotional, and environmental domains were used as cutoffs to define higher and lower scores. A multinomial logistic regression model was used to define the parameters associated with lower scores. RESULTS: Diabetes mellitus, dyslipidemia, and obesity were associated with lower scores in the physical domain. Dyslipidemia was also associeted with lower scores in the psychological domain. Male gender and regular physical activity had protective effects on quality of life. Aging was inversely associated with decreased quality of life in the environmental domain. CONCLUSION: The presence of cardiovascular risk factors is related to a decreased quality of life. Conversely, male gender and regular physical activity had protective effects on quality of life. These findings suggest that exercising should be further promoted by health-related public programs, with a special focus on women.

Knowledge and attitudes of health care workers from intensive care units regarding nosocomial transmission of influenza: a study on the immediate pre-pandemic period

The transmission of influenza in health care settings is a major threat to patients, especially those with severe diseases. The attitude of health care workers (HCWs) may influence the transmission of countless infections. The current study aimed to quantify knowledge and identify attitudes of HCWs involved in intensive care units (ICUs) regarding the risk of nosocomial influenza transmission. A questionnaire was applied through interviews to HCWs who worked in one of the five ICUs from a teaching hospital. Questions about influenza were deliberately dispersed among others that assessed several infectious agents. Forty-two HCWs were interviewed: nine physicians, ten nurses and 23 nursing technicians or auxiliaries. Among the 42 HCWs, 98% were aware of the potential transmission of influenza virus in the ICUs, but only 31% would indicate droplet precautions for patients with suspected infection. Moreover, only 31% of them had been vaccinated against influenza in the last campaign (2008). Nursing technicians or auxiliaries were more likely to have been vaccinated, both by univariate and multivariable analysis. When asked about absenteeism, only 10% of the study subjects stated that they would not go to work if they had an influenza-like illness. Those findings suggest that, in non-pandemic periods, influenza control in hospitals requires strategies that combine continuous education with changes in organizational culture.

Health surveys and use of maternal and child health care services in three municipalities within the São Paulo metropolitan area

Objectives. To describe the changes in the use of maternal and child health care services by residents of three municipalities-Embu, Itapecerica da Serra, and Taboao da Serra-in the São Paulo metropolitan area, 12 years after the implementation of the Unified Health System (SUS) in Brazil, and to analyze the potential of population-based health care surveys as sources of data to evaluate these changes.Methods. Two population-based, cross-sectional surveys were carried out in 1990 and 2002 in municipalities located within the São Paulo metropolitan area. For children under 1 year of age, the two periods were compared in terms of outpatient services utilization and hospital admission; for the mothers, the periods were compared in terms of prenatal care and deliveries. In both surveys, stratified and multiple-stage conglomerate sampling was employed, with standardization of interview questions.Results. The most important changes observed were regarding the location of services used for prenatal care, deliveries, and hospitalization of children less than 1 year of age. There was a significant increase in the use of services in the surrounding region or hometown, and decrease in the utilization of services in the city of São Paulo (in 1990, 80% of deliveries and almost all admissions for children less than 1 year versus 32% and 46%, respectively, in 2002). The use of primary care units and 24-hour walk-in clinics also increased. All these changes reflect care provided by public resources. In the private sector, there was a decrease in direct payments and payments through company-paid health insurance and an increase in payments through self-paid health insurance.Conclusions. The major changes observed in the second survey occurred simultaneous to the changes that resulted from the implementation of the SUS. Population-based health surveys are adequate for analyzing and comparing the utilization of health care services at different times.

Breastfeeding knowledge and practice of health professionals in public health care services

Objetivou-se avaliar conhecimentos e práticas sobre aleitamento materno de profissionais que atendem lactentes em unidades de atenção básica, ou maternidades públicas, de município do interior paulista, Brasil. É estudo epidemiológico, sendo a população composta por 89 enfermeiros e médicos. Suas respostas a um questionário estruturado foram analisadas no total e segundo o local de trabalho, aplicando-se o teste de diferença de proporções (qui-quadrado), considerando-se p<0,05 como nível crítico. Como parâmetros de acertos foram consideradas as recomendações do Ministério da Saúde. As diferenças significativas para conhecimentos e práticas, segundo o local de trabalho, foram restritas a alguns aspectos, com resultados discretamente melhores dos escores médios de acertos dos profissionais das unidades de atenção básica. Independente do local de trabalho, verificou-se desempenho regular e ruim em diferentes aspectos estudados, indicando que possíveis intervenções para a capacitação nessa temática deverão incluir profissionais de todos os níveis de atenção à saúde.

Experiences of family members regarding the oral health care of children

Este estudo objetivou verificar a compreensão das experiências dos familiares em relação ao cuidado com a saúde bucal das crianças. É estudo qualitativo, realizado em 2007, em distrito de saúde do município de Ribeirão Preto, SP, com 12 cuidadores. Utilizou-se referencial teórico da vulnerabilidade e a perspectiva hermenêutica. Três categorias empíricas foram elaboradas: os significados do cuidado com a saúde bucal, em busca das causas e da prevenção de agravos bucais e a realidade dos serviços de saúde bucal. Entre outros elementos potencializadores da vulnerabilidade infantil aos agravos bucais, emergiu a supervalorização da causalidade biológica, do atendimento de alta complexidade e da odontologia estética e, entre os protetores, a valorização do saber popular e a integração de ações e conhecimentos profissionais. Aponta-se para a revisão das estratégias de prevenção e promoção de saúde bucal, fornecendo elementos para auxiliar os serviços de saúde a reorganizarem o cuidado com a saúde bucal de crianças.
