Family context and duration of untreated psychosis (DUP): Results from the Sao Paulo Study

Background: Duration of untreated psychosis (DUP) depends on several factors, including socio-demographic, socioeconomic, clinical and contextual circumstances, such as availability of mental health services. Living arrangements may also play a role, especially in low- and middle-income countries, where most people who develop psychosis live with their relatives. Methods: Population-based study of first-episode psychosis in Sao Paulo, Brazil. Participants were aged 18-64 years, lived in a defined geographic area of the city and had a first contact in life with mental health services due to a psychotic episode. Duration of untreated psychosis was defined as the period between onset of first psychotic symptom and first contact with health service due to psychosis. The median DUP was used to classify participants into short and long DUP. Psychopathology, social adjustment and psychiatric diagnoses were made with standardized assessments. Type of service sought and living arrangements were examined. Results: Two hundred participants were included (52% women, 61% non-affective psychoses). The median DUP was 4.1 weeks (inter-quartile range: 1.9-11.4), and was shorter for affective psychoses. Most participants had their first contact with psychiatric emergency services. Those who did not live with a relative (children older than 18 years, parents, partner) were more likely to present long DUP (OR: 2.63; 95%Cl: 0.98-7.04); p = 0.05). Conclusion: The DUP in Sao Paulo was shorter than expected. Living arrangements may play an important role in shortening the DUP in urban centres of low- and middle income countries that have a network of mental health services. (C) 2009 Elsevier B.V.

Análise epidemiológica das causas externas em unidades de urgência e emergência em Cuiabá/Mato Grosso

OBJETIVO: Apesar da importância das causas externas como problema de saúde pública, pouco se conhece sobre a demanda de serviços de urgência e emergência. Este estudo tem como objetivo caracterizar a morbidade por causas externas em unidades de urgência e emergência do município de Cuiabá/MT. MÉTODO: Trata-se de um estudo transversal e descritivo. Foram analisadas 3.786 vítimas de causas externas atendidas pelas cinco unidades de urgência e emergência da Secretaria Municipal de Saúde de Cuiabá/MT, no período de 1 de maio a 30 de junho de 2005. RESULTADOS: Aproximadamente 88% dos atendimentos se referiam a vítimas de acidentes, 9% corresponderam a agressões e 2% a lesões autoprovocadas. Os acidentes de transportes representaram 22% dos atendimentos, sendo os motociclistas as principais vítimas (49%); as quedas foram as causas mais freqüentes no grupo de outras causas externas de traumatismos acidentais. A prevalência em homens superou a de mulheres. A maior parte das vítimas era menor de 40 anos (79%). No entanto, a análise por tipo de causa externa apresenta resultados diferentes segundo sexo e faixa etária. Cerca da metade dos eventos ocorreu em casa e, em sua maioria, as vítimas receberam alta após o atendimento, sendo que a taxa de mortalidade foi baixa (0,4%). CONCLUSÃO: Os resultados revelam a importância da análise sistemática dos dados referentes às vítimas de acidentes e violência atendidas em unidades de urgência e emergência, como complemento às informações sobre mortalidade e morbidade hospitalar visando o monitoramento dessas causas.

Ocorrências em pronto-socorro: eventos sentinela para o monitoramento da atenção básica de saúde

O estudo tem como ponto de partida a hipótese de que determinadas ocorrências nosológicas atendidas em pronto-socorro, escolhidas com base no conceito de evento sentinela, podem estar relacionadas a falhas da atenção básica e ser utilizadas na formulação de um indicador para o monitoramento desta atenção. Foram utilizados dados quantitativos e qualitativos sobre ocorrências previamente escolhidas e atendidas em pronto-socorro. Usando-se a triangulação de métodos, verificaram-se as diferenças das freqüências dessas ocorrências entre as áreas/unidades básicas de saúde (UBS) de procedência dos pacientes e as motivações determinantes da procura pelo pronto-socorro. As freqüências das ocorrências apresentaram valores de 30% a 42,8% conforme a área/UBS de procedência (Ç2 = 9,19 e p = 0,027). As entrevistas sugeriram a existência de causalidade entre o motivo declarado da procura do pronto-socorro e a atuação das unidades básicas. Conclui-se que: (1) a freqüência das ocorrências escolhidas foi influenciada pelas áreas/UBS de procedência das pessoas; (2) essa influência decorre, em parte, da situação da atenção básica; (3) o instrumental estudado é simples e pode contribuir para o gestor local no acompanhamento cotidiano da situação dos serviços básicos.

Spatial analysis of urban violence based on emergency room data

OBJECTIVE: To estimate the spatial intensity of urban violence events using wavelet-based methods and emergency room data. METHODS: Information on victims attended at the emergency room of a public hospital in the city of São Paulo, Southeastern Brazil, from January 1, 2002 to January 11, 2003 were obtained from hospital records. The spatial distribution of 3,540 events was recorded and a uniform random procedure was used to allocate records with incomplete addresses. Point processes and wavelet analysis technique were used to estimate the spatial intensity, defined as the expected number of events by unit area. RESULTS: Of all georeferenced points, 59% were accidents and 40% were assaults. There is a non-homogeneous spatial distribution of the events with high concentration in two districts and three large avenues in the southern area of the city of São Paulo. CONCLUSIONS: Hospital records combined with methodological tools to estimate intensity of events are useful to study urban violence. The wavelet analysis is useful in the computation of the expected number of events and their respective confidence bands for any sub-region and, consequently, in the specification of risk estimates that could be used in decision-making processes for public policies.

Limites do cuidado: representações e processos inconscientes sobre a população na porta de entrada de um hospital de emergência

Este artigo apresenta parte dos resultados de uma investigação voltada para a análise dos limites e possibilidades que os processos intersubjetivos e inconscientes presentes nos serviços de saúde estabelecem para o exercício da solidariedade, para a cooperação e para a produção do cuidado com a vida. Elegeu-se como estudo de caso um hospital público de emergência, situado no Município do Rio de Janeiro, Brasil. A Psicossociologia francesa, de inspiração clínica psicanalítica, a teoria psicanalítica sobre os processos intersubjetivos e grupais e a Psicodinâmica do Trabalho são os referenciais centrais que orientaram o desenho da investigação e a análise do material empírico. As representações psíquicas e os processos inconscientes relativos à população e suas demandas, produzidos pelos trabalhadores de saúde do hospital estudado, foram analisados, discutindo-se suas conseqüências sobre a produção do cuidado. Algumas imagens se destacaram, como a "carência", utilizada como uma categoria encobridora da diversidade da demanda, num processo inconsciente de múltiplas reduções: da negação do sofrimento social à negação da condição de humanidade dos pacientes.

Inequalities in access and utilization of dental services: a cross-sectional study in an area covered by the Family Health Strategy

This cross-sectional study aimed to investigate the presence of inequalities in the access and use of dental services for people living in the coverage area of the Family Health Strategy (FHS) in Ponta Grossa, Paraná State, Brazil, and to assess individual determinants related to them. The sample consisted of 747 individuals who answered a pre-tested questionnaire. Data analysis was performed by chi-square test and Poisson regression analysis, obtaining explanatory models for recent use and, by limiting the analysis to those who sought dental care, for effective access. Results showed that 41% of the sample had recent dental visits. The lowest visit rates were observed among preschoolers and elderly people. The subjects who most identified the FHS as a regular source of dental care were children. Besides age, better socioeconomic conditions and the presence of a regular source of dental care were positively associated to recent dental visits. We identified inequalities in use and access to dental care, reinforcing the need to promote incentives to improve access for underserved populations.

Características dos nascidos vivos, das mães e mortalidade neonatal precoce na Região Metropolitana de São Paulo, Brasil

O objetivo foi descrever as características do recém-nascido, da mãe e da mortalidade neonatal precoce, segundo local de parto, na Região Metropolitana de São Paulo, Brasil. Utilizou-se coorte de nascidos vivos vinculados aos respectivos óbitos neonatais precoces, por técnica determinística. Identificou-se o parto domiciliar a partir da Declaração de Nascido Vivo e os ocorridos em estabelecimentos a partir da vinculação com o Cadastro Nacional de Estabelecimentos de Saúde. Foram estudados 154.676 nascidos vivos, dos quais 0,3% dos nascimentos ocorreram acidentalmente em domicílio, 98,7% em hospitais e menos de 1% em outro serviço de saúde. A mortalidade foi menor no Centro de Parto Normal e nas Unidades Mistas de Saúde, condizente com o perfil de baixo risco obstétrico. As taxas mais elevadas ocorreram nos prontos-socorros (54,4 óbitos por mil nascidos vivos) e domicílios (26,7), representando um risco de morte, respectivamente, 9,6 e 4,7 vezes maior que nos hospitais (5,6). Apesar da alta predominância do parto hospitalar, há um segmento de partos acidentais tanto em domicílios como em prontos-socorros que merece atenção, por registrar elevadas taxas de mortalidade neonatal precoce.

Influence of self-perceived oral health and socioeconomic predictors on the utilization of dental care services by schoolchildren

The influence of socioeconomic factors and self-rated oral health on children's dental health assistance was assessed. This study followed a cross-sectional design, with a multistage random sample of 792 12-year-old schoolchildren from Santa Maria, a city in southern Brazil. A dental examination provided information on the prevalence of dental caries (DMFT index). Data about the use of dental service, socioeconomic status, and self-perceived oral health were collected by means of structured interviews. These associations were assessed using Poisson regression models (prevalence ratio; 95% confidence interval). The prevalence of regular use of dental service was 47.8%. Children from low socioeconomic backgrounds and those who rated their oral health as "poor" used the service less frequently. The distribution of the kind of oral healthcare assistance used (public/private) varied across socioeconomic groups. The better-off children were less likely to have used the public service. Clinical, socioeconomic, and psychosocial factors were strong predictors for the utilization of dental care services by schoolchildren.

Self-medication: initial treatments used by patients seen in an ophthalmologic emergency room

OBJECTIVE: This study seeks to identify practices of self-medication in the treatment of ocular emergencies. We examine patients' use of both homemade preparations and manufactured products before seeking specialized care. MATERIALS AND METHODS: We conducted a cross-sectional analytic survey of consecutive patients seen in the ophthalmology emergency room of a teaching hospital. RESULTS: The sample included 561 subjects, 51.3% males and 48.7% females, with a mean age of 39.8 years. Prior to seeking emergency care, 40.5% reported self-medicating; 29.4% used a homemade preparation (13.9% referred to an industrialized product like boric acid as a homemade preparation), and 11.1% used a manufactured product. The most frequently used products included a boric acid solution (53.3%), a normal saline solution (35.7%), herbal infusions (6.1%) and breast milk (4.8%). Viral conjunctivitis was the most frequent diagnosis (24.4%), followed by the presence of a corneal foreign body (7.4%). No significant differences were found in the self-treatment of ocular injuries according to gender (p = 0.95), level of education (p = 0.21) or age (p = 0.14). In addition, self-medication practices were not related to the medically judged severity of the condition. CONCLUSION: Patients often attempt to treat conditions that require ophthalmologic emergency care by self-medicating with homemade or manufactured products. The most widely used products include boric acid, normal saline, leaf infusions and breast milk. This behavior occurs independently of educational level, gender, age or the nature of the ocular condition. Self-medication is a culturally driven practice that is used even in cases of acute ocular injuries.

Rede de atenção à saúde mental de base comunitária: a experiência de Santo André

Os distúrbios psiquiátricos constituem um grave problema de saúde pública. Por muitos anos, a única terapêutica disponível ao portador de transtornos mentais era a internação em hospitais psiquiátricos. Hoje a Organização Mundial de Saúde recomenda os serviços de base comunitária como modelo de tratamento em saúde mental. Assim, o objetivo é descrever as características de uma rede de atenção à saúde mental de base comunitária no município de Santo André, SP. Foi realizado um estudo retrospectivo do tipo descritivo, em dados secundários do período de 1987 a 2006. O estudo incidiu sobre o histórico, a infra-estrutura, os recursos humanos, a produção, as práticas e processos de trabalho dos serviços de saúde mental de Santo André. Foram analisados documentos do Programa Municipal de Saúde Mental, da Secretaria Municipal de Saúde, da Prefeitura de Santo André, da Associação José Martins de Araújo Júnior-Organização Social De Volta Para Casa. A Secretaria Municipal de Saúde proveu meios para uma transformação dos serviços de saúde mental no período estudado, partindo de um atendimento exclusivamente manicomial para uma rede de serviços de saúde mental com modelo centrado na comunidade, focando a doença no aspecto psicossocial e com abordagem por equipe multiprofissional. Estas ações no município de Santo André foram corroborativas aos esforços da sociedade civil e o pleno desenvolvimento da mudança do modelo hospitalocêntrico

Perfil dos usuários de um centro de atenção psicossocial infantojuvenil da grande São Paulo, Brasil

INTRODUÇÃO: os Centros de Atenção Psicossocial Infantojuvenil (CAPSi) constituem ponta de lança das ações da Reforma Psiquiátrica Brasileira e têm por finalidade o atendimento de crianças e adolescentes com transtornos psíquicos graves. O objetivo é caracterizar o perfil dos usuários de um CAPSi, considerando sexo, idade, hipótese diagnóstica, origem do encaminhamento, inserção escolar e motivo de consulta. MÉTODO: por meio de um protocolo, foram coletados dados da totalidade de prontuários ativos de uma unidade da Grande São Paulo - cento e três - no mês de janeiro de 2008. RESULTADOS: a maioria dos usuários atendidos está na faixa etária de cinco a quinze anos (68,9 por cento) e é do sexo masculino (61,2 por cento). O grupo de transtornos de comportamento e transtornos emocionais corresponde a 21,4 por cento, seguido pelos transtornos do desenvolvimento global (16,2 por cento) e retardo mental (10,5 por cento). A maioria dos usuários foi encaminhada pelo Conselho Tutelar (22,3 por cento) e tiveram como principal motivo da consulta queixas neuromotoras (17,5 por cento), escolares (15,5 por cento) e sociocomportamentais (14,6 por cento). CONCLUSÕES: o número elevado de crianças com problemas neuromotores pode indicar características específicas da instituição estudada que absorveu pacientes e profissionais de um antigo serviço de reabilitação. O grande número de questões relevantes não encontradas apontam para a falta de padronização dos prontuários

Vigilância em saúde no Brasil: os desafios dos riscos sanitários do século XXI e a necessidade de criação de um sistema nacional de vigilância em saúde

The technological development experienced in the contemporary world are transforming society and relations between State and people. The mobility of human being has reached levels never before imagined and a person can move from one side of the world to the other side in less than 24 hours. This mobility also includes goods and services, giving the keynote of the globalized world of the XXI Century. In this context, the risks of diseases and others health problems are intensely amplified. Nowadays, an epidemic that begins in China can arrive in Brazil the following day. Brazil recognizes health as a universal right and also consider it a State's obligation. Therefore, the State of Brazil is obligated to organize itself to eliminate or control health risks. Today, the organization of the Brazilian State regarding the surveillance of risks of diseases and other health problems is fragmented and includes sanitary surveillance (focused on goods, products and services), epidemiological surveillance (diseases and investigations of other risks) and environmental surveillance in health (the environment in general, including the workplace). This fragmentation causes problems for the management and consolidation of strategic information for health protection. Brazil has the need to think about an other model of organization that put together all "kinds" of surveillances within a single coordinated system, called the National System of Health Surveillance, which would be able to coordinate the various specialties of health surveillance that exists in the country in order to provide a effective system of information and health surveillance, able to face emergency situations of public health

Health services performance for TB treatment in Brazil: a cross-sectional study

Background: Researches to evaluate Primary Health Care performance in TB control in Brazil show that different cities aggregate local specificities in the dynamics of coping with the disease. This study aims to evaluate health services' performance in TB treatment in cities across different Brazilian regions. Methods: This cross-sectional study was conducted in five cities that are considered priorities for TB control in Brazil: Itaborai (ITA), Ribeirao Preto (RP) and Sao Jose do Rio Preto (SJRP) in the Southeast; Campina Grande (CG) and Feira de Santana (FS) in the Northeast. Data were collected through interviews with 514 TB patients under treatment in 2007, using the Primary Care Assessment Tool adapted for TB care in Brazil. Indicators were constructed based on the mean response scores (Likert scale) and compared among the study sites. Results: ""Access to treatment"" was evaluated as satisfactory in the Southeast and regular in the Northeast, which displayed poor results on 'home visits' and 'distance between treatment site and patient's house'. ""Bond"" was assessed as satisfactory in all cities, with a slightly better performance in RP and SJRP. ""Range of services"" was rated as regular, with better performance of southeastern cities. 'Health education', 'DOT' and 'food vouchers' were less offered in the Northeast. ""Coordination"" was evaluated as satisfactory in all cities. ""Family focus"" was evaluated as satisfactory in RP and SJRP, and regular in the others. 'Professional asking patient's family about other health problems' was evaluated as unsatisfactory, except in RP. Conclusions: Two types of obstacles are faced for health service performance in TB treatment in the cities under analysis, mainly in the Northeast. The first is structural and derives from difficulties to access health services and actions. The second is organizational and derives from the way health technologies and services are distributed and integrated. Incentives to improve care organization and management practices, aimed at the integration of primary, secondary and tertiary services, can contribute towards a better performance of health services in TB treatment.

The variability and predictors of quality of AIDS care services in Brazil

Background: Since establishing universal free access to antiretroviral therapy in 1996, the Brazilian Health System has increased the number of centers providing HIV/AIDS outpatient care from 33 to 540. There had been no formal monitoring of the quality of these services until a survey of 336 AIDS health centers across 7 Brazilian states was undertaken in 2002. Managers of the services were asked to assess their clinics according to parameters of service inputs and service delivery processes. This report analyzes the survey results and identifies predictors of the overall quality of service delivery. Methods: The survey involved completion of a multiple-choice questionnaire comprising 107 parameters of service inputs and processes of delivering care, with responses assessed according to their likely impact on service quality using a 3-point scale. K-means clustering was used to group these services according to their scored responses. Logistic regression analysis was performed to identify predictors of high service quality. Results: The questionnaire was completed by 95.8% (322) of the managers of the sites surveyed. Most sites scored about 50% of the benchmark expectation. K-means clustering analysis identified four quality levels within which services could be grouped: 76 services (24%) were classed as level 1 (best), 53 (16%) as level 2 (medium), 113 (35%) as level 3 (poor), and 80 (25%) as level 4 (very poor). Parameters of service delivery processes were more important than those relating to service inputs for determining the quality classification. Predictors of quality services included larger care sites, specialization for HIV/AIDS, and location within large municipalities. Conclusion: The survey demonstrated highly variable levels of HIV/AIDS service quality across the sites. Many sites were found to have deficiencies in the processes of service delivery processes that could benefit from quality improvement initiatives. These findings could have implications for how HIV/AIDS services are planned in Brazil to achieve quality standards, such as for where service sites should be located, their size and staffing requirements. A set of service delivery indicators has been identified that could be used for routine monitoring of HIV/AIDS service delivery for HIV/AIDS in Brazil (and potentially in other similar settings).

Urban air pollution and chronic obstructive pulmonary disease-related emergency department visits

Background: Patients with chronic obstructive pulmonary disease (COPD) can have recurrent disease exacerbations triggered by several factors, including air pollution. Visits to the emergency respiratory department can be a direct result of short-term exposure to air pollution. The aim of this study was to investigate the relationship between the daily number of COPD emergency department visits and the daily environmental air concentrations of PM(10), SO(2), NO(2), CO and O(3) in the City of Sao Paulo, Brazil. Methods: The sample data were collected between 2001 and 2003 and are categorised by gender and age. Generalised linear Poisson regression models were adopted to control for both short-and long-term seasonal changes as well as for temperature and relative humidity. The non-linear dependencies were controlled using a natural cubic spline function. Third-degree polynomial distributed lag models were adopted to estimate both lag structures and the cumulative effects of air pollutants. Results: PM(10) and SO(2) readings showed both acute and lagged effects on COPD emergency department visits. Interquartile range increases in their concentration (28.3 mg/m(3) and 7.8 mg/m(3), respectively) were associated with a cumulative 6-day increase of 19% and 16% in COPD admissions, respectively. An effect on women was observed at lag 0, and among the elderly the lag period was noted to be longer. Increases in CO concentration showed impacts in the female and elderly groups. NO(2) and O(3) presented mild effects on the elderly and in women, respectively. Conclusion: These results indicate that air pollution affects health in a gender-and age-specific manner and should be considered a relevant risk factor that exacerbates COPD in urban environments.
