A Política Nacional de Atenção às Urgências (PNAU) foi criada para organizar e planejar a rede de atendimentos, ampliando o acesso e reduzindo as desigualdades responsáveis pela garantia do direito a saúde, com a integração dos níveis de atenção à saúde, como forma de organização nas urgências e emergências. Diretrizes para as organizações de redes loco-regionais de atenção integral às urgências, e conceitos, atribuições e pré-requisitos foram definidos para implementação das UPAs e Salas de estabilização, em locais/unidades estratégicas para configuração dessas redes. As UPAs seriam responsáveis pelo atendimento de casos de complexidade intermediária que visavam estabelecer a relação entre a atenção primária e a atenção terciária, sendo classificadas de acordo com o porte, a capacidade física instalada, o número de leitos disponíveis, gestão de pessoas e a capacidade diária de realizar os atendimentos médicos. Este estudo objetivou analisar a integração e a adequabilidade das UPAs às redes de atenção do Sistema Único de Saúde no Estado do Paraná. Trata-se de um estudo de casos do processo de construção da rede de atenção às urgências e emergências no Paraná através de entrevistas semiestruturadas realizadas em 2012 com coordenadores de uma amostra de 7 UPAs do Paraná em um universo de 14.O critério de escolha da amostra foi realizado a partir da localização, porte, tipo de gestão e abrangência regional. Os dados foram armazenados em planilha eletrônica no formato Microsoft Excel e Stata 11 e apresentados na forma de frequências absolutas e relativas. O sistema de gerenciamento das unidades de pronto-atendimentos no Estado do Paraná ocorre por administração direta via município, e o financiamento das UPAs por via direta entre o Ministério da Saúde e os municípios, não havendo interlocução do governo estadual. Os mecanismos de avaliações estavam presentes em três serviços e com baixa frequência. A demanda das Unidades de Pronto-Atendimento eram maiores do que a sua capacidade. Observou-se a integração parcial das UPAs aos componentes da Rede Paraná Urgência e desigualdade organizacional e de gestão entre os serviços das regiões metropolitanas e interior. Os atendimentos de casos com risco intermediário é realizado conforme o pré-estabelecido para a atenção secundária, entretanto, o atendimento de casos de baixa complexidade em dois serviços não são realizados conforme o proposto, sugerindo desta forma possíveis falhas na atenção primária. Na amostra das UPAs do Paraná, os serviços não estavam adequados com as normativas do Ministério da Saúde conforme o respectivo porte. As UPAs necessitam estar integradas em uma política de redes de atenção em saúde para ampliar a sua resolutividade e garantir os princípios dos SUS / The National Emergency Care Policy (PNAU) was created toward organizing and planning the assistance network, expanding access and reducing inequalities that undermine the right to health, with the integration of healthcare levels as a form of organization at urgencies and emergencies. Guidelines for the organization of local and regional networks of comprehensive attention to urgencies, concepts, attributions and pre-requisites were defined for the implementation of the ECUs and stabilization rooms, at strategic locations/units for the configuration of these networks. The ECUs would be in charge of the assistance to cases of intermediate complexity that aim to establish the relationship between primary and tertiary care, being classified according to their structure, physical capacity installed, number of beds available, personnel management and daily capacity to perform medical services. The purpose of this study was to analyze the integration and adequacy of the ECUs regarding healthcare networks of the Brazilian Unified Health System in the state of Paraná. This is a case study on the construction process of the network of attention to urgencies and emergencies in Paraná, developed through semi-structured interviews conducted in 2012 with coordinators of a sample with 7 ECUs in Paraná among a total of 14. The sample was selected based on the services\' location, structure, management type and regional reach. Data was stored in a spreadsheet of Microsoft Excel and Stata 11 format and presented as absolute and relative frequencies. The management system of the ECUs in Paraná is administered directly by the municipality, and the financing of the ECUs directly between the Health Ministry and the municipalities, without intervention of the state government. The mechanisms of assessment were present in three services, with low frequency. The demand of the Emergence Care Units was higher than their capacity. It was observed a partial integration of the ECUs with the components of Paraná\'s Emergency Network, and organizational and managerial inequality between services in metropolitan regions and towns. The assistance to cases with intermediate risks is performed according to pre-established norms for secondary care; however, the assistance to cases of low complexity in two services is not carried out in accordance with the proposal, suggesting, thus, possible failures in primary care. In the sample of Paraná\'s ECUs, the services did not meet the norms of the Health Ministry according to their respective structure. The ECUs need to be integrated in a healthcare network policy in order to expand their resolution ability and guarantee the principles of the Brazilian Unified Health System

Esta informação torna-se útil para conhecer a demanda desta população frente ao envelhecimento populacional, com implicações para ações e políticas específicas. O modelo comportamental de Andersen foi adotado como referencial teórico. Objetivo – Analisar a associação entre a utilização de serviços de saúde e os fatores de predisposição, capacidade e necessidade, em idosos de 80 anos e mais. Métodos – Estudo de base populacional e corte transversal. Amostra de 103 idosos com 80 anos e mais da área urbana de Cuiabá, selecionados a partir de amostragem aleatória simples, estratificada e por conglomerados em duas etapas. Utilizou-se o questionário BOAS – Brazil Old Age Schedule e realizou-se análise descritiva, teste do qui-quadrado, prevalência bruta e ajustada pela regressão múltipla de Poisson. Resultados: A amostra foi composta por 52 mulheres, média de 84,9±5,4 anos; 53,4% referiram nenhuma escolaridade, 87,4% não trabalham e 66,0% possuem renda mensal de até um salário mínimo. Mais da metade (58,3%) declararam não ter companheiro(a), grande parte tiveram filhos e 92,1% moram com alguém. A maioria autoavaliou sua saúde ótima ou boa (73,8%), declarou problema de saúde (81,6%) e tomar remédio (78,6%); 59,2% utilizaram serviço de saúde nos últimos três meses. O perfil de idosos que utilizaram serviço de saúde é composto pelos mais velhos, mulheres, com quatro anos ou mais de escolaridade e renda maior que três salários mínimos, que não moram sozinhos, que relataram problemas de saúde (principalmente dois ou mais problemas) e utilizam remédios (principalmente três ou mais). Foi encontrada associação estatisticamente significante apenas entre utilização de serviços de saúde e os fatores de necessidade: ter problema de saúde (um problema RP=1,54 e dois ou mais problemas RP=1,25), tomar remédio (um ou dois RP=1,41 e três ou mais remédios RP=1,22). Conclusões: Referir problema de saúde e usar medicamentos estão associados à utilização de serviços de saúde por idosos de 80 anos e mais. Essas informações contribuem para ampliar o conhecimento sobre idosos de 80 anos e mais de um país em desenvolvimento e podem subsidiar políticas e programas de atenção à saúde, assistenciais e preventivos, com intervenção sobre os fatores associados à utilização de serviços de saúde, para que este uso seja mais adequado. / Studies on population 80 years and over are scarce in developing countries, especially regarding the health services utilization. This information is useful to know the demand of this population compared to population aging, with implications for specific actions and policies. The Andersen´s behavioral model of was the theoretical approach. Objective – To analyze the association between the health services utilization and the predisposing, need and ability factors in the elderly 80 years and older. Methods – This is a cross-sectional study, population-based. Sample of 103 elderly aged 80 years and over in the urban area of Cuiabá-MT, selected based on simple random sampling, stratified and clusters in two stages. We used Brazil Old Age Schedule – BOAS. In the data analysis were used descriptive statistics, the chi-square test, prevalence ratio and Poisson multiple regression. Results: The sample were composed of 52 women, mean 84.9 ± 5.4 years; 53.4% had no schooling, 87.4% do not work and 66.0% have a monthly income of a minimum wage. More than half of the elderly (58.3%) declared not to have a partner, most had children and 92.1% live with someone. Most have a good or excellent health self assessment (73.8%), reported health problem (81.6%) and take medicines (78.6%); 59.2% used health service in the last three months. The elderly who used the health service are older, women, with four or more years of education, incomes higher than three minimum wages, who do not live alone, who reported health problems (mainly two or more problems) and use medicines (mainly three or more). Statistically significant association was found only between the health services utilization and factors of need: having health problems (one problem RP = 1.54 and two or more problems PR = 1.25), taking medicines (one or two RP = 1.41 and three or more PR = 1.22). Conclusions: To report two or more health problems, use medicines, especially one or two, are associated with the use of health services by the elderly 80 years and older. These information contributes to broaden knowledge of aged 80 years and over in a developing country and can develop policies and programs to health care, with intervention in associated factors with the health services utilization for this use can be most appropriate.

Indiana University-Purdue University Indianapolis (IUPUI) / Depression in African American (AA) adolescents is a prevalent mental health problem, can result in serious concurrent and long-term effects, and is associated with health disparities due to underutilization of mental health services. Initiatives to reduce disparities among depressed AA adolescents require a greater understanding of the experience of depression from their own point of view. The purpose of this dissertation was to generate a comprehensive theoretical framework that describes how AA adolescents experience depression throughout adolescence. The information gained about how AA adolescents understand and manage depressive symptoms, and in some cases seek and use mental health services will contribute to initiatives to reduce behavioral health disparities. This dissertation project was composed of two components. The first component was an integrative review of studies that explored associations between adolescent coping responses and depression. The integrative review summarized and integrated research from the past ten years that examined coping techniques of depressed adolescents. It revealed that the use of active coping strategies plays an important role in recovery from depression. The second component was a grounded theory study which included a sample of 22 community-based AA young adults (ages 18-21) and 5 clinic-based AA adolescents (ages 13-17). During semi-structured interviews, participants described their experiences with depression as adolescents. In addition, a timeline was constructed that included major events related to the unfolding of depression, including treatment seeking, which occurred during adolescence. Data generated from the grounded theory study were analyzed and resulted in two qualitatively derived products. The first is a typology titled Being With Others that depicts interaction patterns of depressed AA adolescents with people in their lives. The five categories in the typology are keeping others at bay, striking out at others, seeking help from others, joining in with others, and having others reach out. The second product is a theoretical framework titled Weathering through the Storm that describes how depression in AA adolescents unfolds over time. The five phases of the framework are labeled enduring stormy weather, braving the storm alone, struggling with the storm, finding shelter in the storm, and moving out of the storm.

In this study, the utilization of palliative care services, acute care services, and location of death for clients who were palliative and receiving services from Champlain Community Care Access Centre (CCAC) in Ontario during their last month of life were investigated. An adaptation of Andersen?s Behavioral Model of Health Services Utilization provided context and structure to this study. This is an historical, quantitative descriptive study using chart audits for data collection. The data on CCAC clients who were palliative and who died during the month of July 2009 were tracked during their last month of life. Collection of socio-demographic data, services provided through CCAC, emergency department visits, hospital admissions, and location of death provided the data for this study. The clients who died at home used more CCAC services than those who died at other locations and frequently community palliative care physicians provided their medical care. The findings of this study included: 1) The majority of the clients, who expressed a preference, died in their preferred location. 2) The role of community palliative care physicians was an important component of the services that supported the clients to die in their location of choice. 3) Over 25% of the study sample died in a hospital and the clients used a large number of in-patient hospital days with one quarter of the hospital deaths taking place in an emergency department or an intensive care unit. 4) During the last month of life, 25% of the clients received chemotherapy and/or radiation therapy. 5) The clients who died at home used more CCAC services than those who died in other locations and who used institutional resources. The implications for practice, policy, research, and education are discussed.

This dissertation consists of three empirical essays investigating different aspects of health care for children and families. The first essay examines the effectiveness of adherence to American Academy of Pediatrics guidelines for preventive pediatric health care. Using a national longitudinal sample of children age two years and younger, we investigate whether compliance with prescribed periodic well-child care visits has beneficial effects on child health. We find that increased compliance improves child health. In particular, higher compliance lowers future risks of fair or poor health, of some history of a serious illness and of having a health limitation. The second essay examines child health care utilization in relation to maternal labor supply. We test the hypothesis that working-mothers trade off the advantages of greater income against the disadvantages of less time for other valuable tasks, such as seeking health care for their children. This tradeoff may result in positive, negative, or no net impacts on child health investment. We estimate health care demand regressions that include separate variables for mother’s labor supply and her labor income. Our results indicate that higher maternal work hours reduce child health care visits; higher maternal earnings increase them. In addition, wage-employment, as opposed to self-employment, is detrimental to child health investment. A further finding is that preventive care demand for younger children is less sensitive to maternal time and income changes. We also find that detrimental time effects dominate beneficial income effects. The third essay studies intra-household resource allocation as it pertains to its demand for preventive medical care. We test the income-pooling hypothesis of the common preference model by using individual specific medical care consumption data and present evidence on the allocation of household resources to the medical needs of the child, husband and wife. Our results are in line with the findings of previous studies that emphasize the ongoing importance of the traditional gender role of woman as the primary caregiver. We find that the resources of the wife have a greater positive impact on child’s and her own preventive care demand than does the resources of the husband. In contrast to most studies from developing countries, we find that US families do not exhibit differential health care demand based on child gender. It is also noteworthy that the wife’s education level has a greater positive impact than that of her husband does on both the husband’s and her own preventive care utilization. / text

Introcução: Estima-se que, no mundo, mais de 350 milhões de pessoas de todas as idades tenham depressão. Em 2010, a depressão foi a segunda principal causa de anos vividos com incapacidade. Embora haja tratamentos eficazes, a proporção de casos diagnosticados e tratados é baixa em todo o mundo, menor ainda nos países de média e baixa renda. Objetivos. Estimar a prevalência de Episódio de Depressão Maior (EDM) na população de 20 anos ou mais cadastrada na Estratégia Saúde da Família (ESF) em dois municípios do Estado do Amazonas (Coari e Tefé); avaliar a associação de EDM com características individuais e investigar a associação entre EDM e utilização de serviços de saúde. Método. Estudo de corte transversal conduzido entre agosto de 2013 e maio de 2014 com amostra representativa da população com 20 anos ou mais, cadastrada na ESF da área urbana dos municípios de Coari e Tefé. Os desfechos \"Depressão maior\" e \"Utilização de Serviços de Saúde\" foram avaliados com a escala Patient Health Questionnaire-9 (PHQ-9) e questões sobre uso de serviços de atenção primária, urgência ou emergência e atenção médica especializada. Foram avaliadas as seguintes exposições: características demográficas e socioeconômicas, apoio social, eventos de vida estressantes, uso de tabaco e álcool, morbidades físicas e tratamento para transtornos mentais. As entrevistas foram realizadas no domicílio do participante. Regressão de Poisson foi utilizada para examinar a associação entre EDM e os fatores de exposição; os resultados foram apresentados como razão de prevalência, com os respectivos intervalos de confiança de 95% (IC 95%). Resultados. A prevalência geral de EDM foi 19,1% (IC 95% 17,2-21,1), sendo 22,2% (IC 95% 19,3-25,0) para mulheres e 16,0 (IC 95% 13,4-18,5) para homens. As prevalências de EDM em Coari e Tefé foram 18,3% (IC 95% 15,7-21,0) e 19,9% (IC 95% 17,2-22,7), respectivamente. Sexo feminino, ausência de apoio social de amigos/colegas, maior número de eventos de vida produtores de estresse e de morbidades físicas foram associados independentemente com depressão maior. Baixa escolaridade e baixa renda, uso de tabaco e uso de risco de álcool foram associados com depressão maior nas análises não ajustadas. EDM foi independentemente associado com a utilização dos três tipos de serviço de saúde investigados. Menos que 4,0% da população estudada recebiam algum tipo de tratamento relacionado à saúde mental. Conclusão. O Estado do Amazonas tem altos índices de desemprego, pobreza e baixa escolaridade, fatores de risco conhecidos para depressão. Uma parcela dos habitantes de Coari e Tefé apresentou indicadores de desvantagem social. Neste contexto, a alta prevalência de EDM encontrada no estudo, cerca de um em cada cinco adultos, não surpreende. As características individuais associadas com EDM nestes municípios são similares aos fatores de risco para depressão no Brasil e em outras partes do mundo. Apesar dos participantes com depressão utilizarem com maior frequência os serviços de saúde, apenas uma pequena proporção da população estudada recebia tratamento para transtornos mentais. Existe uma grande lacuna para o tratamento de depressão no Estado do Amazonas. Programas de tratamento que incluam identificação e tratamento de depressão no contexto da atenção primária devem ser desenvolvidos / Introduction. It is estimated that more than 350 million people of all ages have depression. In 2010, depression was the second leading cause of years lived with disability. Although there are effective treatments, the proportion of cases diagnosed and treated is low around the world, and even smaller in low and middle income countries. Objective. To estimate the prevalence of Major Depressive Episode (MDE) in the population aged 20 years or over enrolled in Brazil\'s Family Health Strategy (FHS) in two municipalities in the state of Amazonas: Coari and Tefé; to evaluate the association of MDE with the individuals\' characteristics; and to investigate the association of MDE with use of health services. Method. Cross-sectional study conducted between August 2013 and May 2014 with a representative sample of the population aged 20 or over enrolled in the FHS in the urban area of Coari and Tefé. The outcomes \"major depression\" and \"use of health services\" were assessed with the Patient Health Questionnaire-9 scale (PHQ-9) and questions about the use of primary care services, as well as emergency and specialized medical care. The following exposure variables were evaluated: demographic and socioeconomic characteristics, social support, stressful life events, use of tobacco and alcohol, physical morbidities and treatment for mental disorders. Interviews were carried out at the participants\' home. Poisson regression was used to examine the association between MDE and exposure factors; results are presented as prevalence ratios, with its respective 95% confidence interval (95% CI). Results. The overall prevalence of MDE was 19.1% (95% CI 17.2 - 21.1) and 22.2% (95% CI 19.3 - 25.0) for women and 16.0 (95% 13.4 - 18.5) for men. The prevalence of MDE in Coari and Tefé were 18.3% (95% CI 15.7 - 21.0) and 19.9% (95% CI 17.2 - 22.7), respectively. Being a woman, lack of social support from friends/colleagues, increased number of stressful life events and physical morbidity were independently associated with major depression. Lower formal education and income, tobacco use and risk use of alcohol were associated with MDE in unadjusted analysis. MDE was independently associated with use of three types of health care investigated. Less than 4.0% of the study population received any type of treatment related to mental health. Conclusion. The state of Amazonas has high rates of unemployment, poverty and low education achievement, known risk factors for depression. A portion of the inhabitants of Coari and Tefé presented indicators of social disadvantage. In this context, the high prevalence of MDE - about one in five adults - is not surprising. Individual characteristics associated with MDE in these municipalities are similar to risk factors for depression in Brazil and worldwide. Although participants with depression used health services frequently, only a small proportion of the study population received treatment for mental disorders. There is a large treatment gap for depression in the state of Amazonas. Treatment programs that include identification and treatment of depression in the context of primary health care should be developed
