The impact of the digital divide on the perceived interest of an e-Marketplace to support healthcare and social care services

In a Europe increasingly aging, it is now recognized the importance and potential of the service industry for ageing well based on information and communication technologies (ICT), as exemplified by the electronic market of social services and health care, the GuiMarket, proposed by the authors. However, this new range of services requires that individuals have advanced digital skills to fully participate in society. Based on the results of a survey made on a sample of 315 individuals, this paper discusses the importance granted GuiMarket and the intended frequency of use, concluding there is a close relationship between ICT access and use that respondents anticipate making of GuiMarket and alike services.

Ambivalent implications of health care information systems: a study in the Brazilian public health care system

This article evaluates social implications of the "SIGA" Health Care Information System (HIS) in a public health care organization in the city of São Paulo. The evaluation was performed by means of an in-depth case study with patients and staff of a public health care organization, using qualitative and quantitative data. On the one hand, the system had consequences perceived as positive such as improved convenience and democratization of specialized treatment for patients and improvements in work organization. On the other hand, negative outcomes were reported, like difficulties faced by employees due to little familiarity with IT and an increase in the time needed to schedule appointments. Results show the ambiguity of the implications of HIS in developing countries, emphasizing the need for a more nuanced view of the evaluation of failures and successes and the importance of social contextual factors.

The right to medical care and its economic consequences: an American dilemma

The concepts of "rights" and of "right to health care" including its evolution in modern times are discussed. The consequences of implementing this right are discussed in economic terms, regarding the situation in the United States of America. A discussion is also included on the limitations of the role of Health Insurance as a measure to solve the problem of providing health care for all individuals.

Notes on health care planning in Latin America and the Caribbean

Attention is called to the fact that the efforts to improve health of populations in Latin America have generally failed. The inequality in the distribution of ill-health is great. The authors accept the fact that the lack of resources available to the health sector may be a restriction towards the improvement of the situation, but they argue that a much more important issue is the misuse of such resources and their maldistribution within the health sector. The lack of integration and coordination between the health services, the conflict of public and private health systems, the under-utilization of existing services and the gap between planning and real implementation are discussed.

Detection of psychiatric morbidity in the primary medical care setting in Brazil

The aims of this study were a) to assess the ability of primary care doctors to make accurate ratings of psychiatric disturbance and b) to evaluate the use of a case-finding questionnaire in the detection of psychiatric morbidity. The estudy took place in three primary care clinics in the city of São Paulo, Brazil, during a six-month survey. A time sample of consecutive adult attenders were asked to complete a case-finding questionnaire for psychiatric disorders (the Self Report Questionnaire - SRQ) and a subsample were selected for a semi-structured psychiatric interview (the Clinical Interview Schedule - CIS). At the end of the consultation the primary care doctors were asked to assess, in a standardized way, the presence or absence of psychiatric disorder; these assessments were then compared with that ratings obtained in the psychiatric interview. A considerable proportion of minor psychiatric morbidity remained undetected by the three primary care doctors: the hidden morbidity ranged from 22% to 79%. When these were compared to those of the case-finding questionnaire, they were consistently lower, indicating that the use of these instruments can enhance the recognition of psychiatric disorders in primary care settings. Four strategies for adopting the questionnaire are described, and some of the clinical consequences of its use are discussed.

Metodological issues in measuring the detection of emotional disorders by primary care physicians: a review of the literature

A series of studies in the field of Epidemiological Psychiatry have been performed over the last two decades, and these have focused on the ability of primary care physicians to detect emotional disorders in the patients that attend their practices. The scientific methodology utilized in these studies is the subject of this review, which contains a discussion concerning: a) interviewer awareness bias; b) accuracy of the instruments and c) medical and psychological concepts involved in defining minor emotional disorders. Suggestions for change in the methodology are made in each of the sections of the review.

Health related quality of life in patients with refractory chronic heart failure undergoing cardiac resynchronization: type of therapeutic response

The benefits of cardiac resynchronization therapy (CRT) in the health-related quality of life (HRQL) are largely demonstrated in selected patients with severe congestive heart failure (CHF). However, the differences between responders and non-responders, with regard to the effect of CRT in the various dimensions that constitute HRQL are still a matter of discussion. Objective: To evaluate the impact of CRT on the HRQL of patients with CHF refractory to optimal pharmacological therapy, within 6 months after CRT. Methods: 43 patients, submitted to successful implantation of CRT, were evaluated in hospital just before intervention and in the outpatient clinic within 6 months after CRT. HRQL was analyzed based on the Kansas City Cardiomyopathy Questionnaire (KCCQ). Patients were classified as super-responders (ejection fraction of left ventricle - LVEF - ≥45% post-CRT), n=15, responders (sustained improvement in functional class and LVEF increased by 15%), n=19, and non-responders (no clinical or LVEF improvement), n=9. Results: In the group of super-responders, CRT was associated with an improvement in HRQL for the various fields and sums assessed (ρ<0.05); in responders, CRT has been associated with an improvement of HRQL in the various fields and sums, except in the self-efficacy dimension (ρ<0.05); in non-responders, CRT was not associated with improvement of HRQL. Conclusion: In a population with severe CHF undergoing CRT, the patients with clinical and echocardiographic positive response, obtained a favorable impact in all dimensions of HRQL, while the group without response to CRT showed no improvement. These data reinforces the importance of HRQL as a multidimensional tool for assessment of benefits in clinical practice.

Child-care attendance and common morbidity: evidence of association in the literature and questions of design

Papers on child-care attendance as a risk factor for acute respiratory infections and diarrhea were reviewed. There was great variety among the studies with regard to the design, definition of exposure and definition of outcomes. All the traditional epidemiological study designs have been used. The studies varied in terms of how child-care attendance in general was defined, and for different settings. These definitions differed especially in relation to the minimum time of attendance required. The outcomes were also defined and measured in several different ways. The analyses performed were not always appropriate, leading to sets of results of uneven quality, and composed of different measures of association relating different exposures and outcomes, that made summarizing difficult. Despite that, the results reported were remarkably consistent. Only two of the papers reviewed failed to show some association between child-care attendance and increased acute respiratory infections, or diarrhea. On the other hand, the magnitude of the associations reported varied widely, especially for lower respiratory infections. Taken together, the studies so far published provide evidence that children attending child-care centers, especially those under three years of age, are at a higher risk of upper respiratory infections, lower respiratory infections, and diarrhea. The studies were not consistent, however, in relation to attendance at child-care homes. Children in such settings were sometimes similar to those in child-care centers, sometimes similar to those cared for at home, and sometimes presented an intermediate risk.

Health financing changes in the context of health care decentralization: the case of three Latin American countries

OBJECTIVE: The results of an evaluative longitudinal study, which identified the effects of health care decentralization on health financing in Mexico, Nicaragua and Peru are presented in this article. METHODS: The methodology had two main phases. In the first, secondary sources of data and documents were analyzed with the following variables: type of decentralization implemented, source of financing, funds for financing, providers, final use of resources, mechanisms for resource allocation. In the second phase, primary data were collected by a survey of key personnel in the health sector. RESULTS: Results of the comparative analysis are presented, showing the changes implemented in the three countries, as well as the strengths and weaknesses of each country in matters of financing and decentralization. CONCLUSIONS: The main financing changes implemented and quantitative trends with respect to the five financing indicators are presented as a methodological tool to implement corrections and adjustments in health financing.

A influência do membro superior no ciclo da marcha

Objectivo: Pretendeu-se avaliar as modificações no comportamento neuro-motor a nível da funcionalidade do membro superior predominantemente afectado e a sua influência no ciclo da marcha de dois indivíduos com Acidente Vascular Cerebral, face a um programa de intervenção em fisioterapia, segundo uma abordagem baseada no Conceito de Bobath. Foi também objectivo averiguar o impacto qualitativo nos componentes e estados de saúde. Metodologia: A avaliação foi realizada em dois indivíduos com sequelas de Acidente Vascular Cerebral, antes e após o plano de intervenção segundo o Conceito de Bobath, através do registo observacional, da Classificação Internacional de Funcionalidade, Incapacidade e Saúde, da Performance-Oriented Mobility Assessment POMA I, da Time Up and Go Test, da Motor Assessement Scale e da Motor Evaluation Scale for Upper Extremity in Patients. Resultados: Obteve-se um incremento da funcionalidade do membro superior predominantemente afectado, com uma atribuição na Classificação Internacional de Funcionalidade, Incapacidade e Saúde de qualificadores correspondentes a dificuldade ligeira a moderada ao nível da mobilidade e dos auto cuidado após o plano de intervenção, repercutindo-se assim numa diminuição da restrição na participação e limitação da actividade. Houve um aumento de score total em todos os instrumentos e escalas de medidas de avaliação utilizadas, tendo os indivíduos alcançado uma maior funcionalidade do membro superior e um padrão de marcha mais eficiente, com uma menor necessidade de recorrer a estratégias compensatórias de movimento. Conclusão: O plano de intervenção, baseado numa abordagem segundo o Conceito de Bobath, essencialmente dirigido para a obtenção de ganhos funcionais ao nível do membro superior predominantemente afectado nos indivíduos em estudo, parece ter contribuído para induzir mudanças no comportamento neuro-motor, verificando-se uma influência no ciclo de marcha ao nível da qualidade e eficiência do movimento.

Detection of anti-Giardia lamblia serum antibody among children of day care centers

OBJETIVES: To detect anti-Giardia lamblia serum antibodies in healthy children attending public day care centers and to assess serological tests as tools for estimating the prevalence of G. lamblia in endemic areas. METHODS: Three separate stool specimens and filter paper blood samples were collected from 147 children ranging from 0 to 6 years old. Each stool sample was processed using spontaneous sedimentation and zinc sulfate flotation methods. Blood samples were tested by indirect immunofluorescence (IIF) and enzyme-linked immunosorbent assay (ELISA) for Giardia IgG. RESULTS AND CONCLUSIONS: Of 147 individuals tested, 93 (63.3%) showed Giardia cysts in their feces. Using IIF and ELISA, serum antibodies were detected in 93 (63.3%) and 100 (68%) samples , respectively. Sensitivity of IIF and ELISA was 82% and 72%, respectively. However, ELISA revealed to be less specific (39%) than IIF (70%). IIF also showed a higher concordance with microscopic examination than ELISA.

Assessment of a consultation-liaison psychiatry and psychology health care program

OBJECTIVE: To investigate the relevance of subjective criteria adopted by a psychiatry and psychology consultation-liaison service, and their suitability in the evaluation of case registries and objective results. METHODS: Semi-structured interviews were conducted and all supervisors of the university hospital service were interviewed. Routinely collected case registries were also reviewed. Standardized assessment with content analysis for each category was carried out. RESULTS: The results showed distortions in the adopted service focus (doctor-patient relationship) and consultant requests. This focus is more on consulting physician-oriented interventions than on patients. DISCUSSION: Evaluation of the relevance of service criteria could help promoting quality assessment of the services provided, mainly when objective criteria have not yet been established to assure their suitability.

Efeitos imediatos da oscilação extra-torácica de alta frequência "THE VESTr", em pacientes críticos submetidos a ventilação mecânica

A retenção de secreções é um problema comum em pacientes sedados e ventilados invasivamente, estas são ponto de partida para o aparecimento de infecções, pneumonia nosocomial e agravamento geral do estado clínico do paciente. Apesar de estudos comprovarem a eficácia da fisioterapia respiratória convencional nestes doentes, outros demonstraram que é cara, operador dependente, de eficácia variada e por vezes causar desconforto e dor. Vários estudos que comprovaram a segurança e eficácia da Alta Frequência Oscilatória Extra Torácica serviram de base para a realização do estudo onde se avaliou os efeitos fisiológicos imediatos da aplicação da técnica e diferenças a médio e longo prazo na comparação entre dois grupos. O VestR força o ar para dentro e para fora dos pulmões aumentando a interacção fluxo/secreções reduzindo a sua viscosidade, ao libertar e mobilizar as secreções, estas são mais facilmente aspiradas, reduzindo o risco de infecção pulmonar. Dez pacientes que cumpriram critérios de inclusão entraram no estudo. Durante dois dias foi aplicado num dos grupos o VestR durante dez minutos, três vezes por dia. Foram registados os parâmetros ventilatórios, cardíacos e de oxigenação para avaliar efeitos fisiológicos imediatos. Para comparação de grupos foram efectuados registos durante as 48h dos parâmetros referidos anteriormente. No período de follow up foram registados os dias de internamento hospitalar na unidade de cuidados intensivos e os dias de ventilação mecânica invasiva. Pelo reduzido tamanho amostral foi usada a estatística descritiva para a análise dos dados. Não foram encontradas diferenças significativas entre os dois grupos, apesar de haver uma tendência de melhoria dos parâmetros fisiológicos imediatos durante a aplicação da técnica. Concluímos que, com a limitação do tamanho amostral, os efeitos positivos imediatos da aplicação da HFCWO neste grupo podem-se revelar um bom indício para a realização de estudos futuros, com tamanhos amostrais superiores e melhor controlados, que comprovem que é uma técnica mais vantajosa e eficaz para o tratamento dos doentes críticos.

Probabilistic linkage in household survey on hospital care usage

OBJECTIVE: To evaluate the potential advantages and limitations of the use of the Brazilian hospital admission authorization forms database and the probabilistic record linkage methodology for the validation of reported utilization of hospital care services in household surveys. METHODS: A total of 2,288 households interviews were conducted in the county of Duque de Caxias, Brazil. Information on the occurrence of at least one hospital admission in the year preceding the interview was obtained from a total of 10,733 household members. The 130 records of household members who reported at least one hospital admission in a public hospital were linked to a hospital database with 801,587 records, using an automatic probabilistic approach combined with an extensive clerical review. RESULTS: Seventy-four (57%) of the 130 household members were identified in the hospital database. Yet only 60 subjects (46%) showed a record of hospitalization in the hospital database in the study period. Hospital admissions due to a surgery procedure were significantly more likely to have been identified in the hospital database. The low level of concordance seen in the study can be explained by the following factors: errors in the linkage process; a telescoping effect; and an incomplete record in the hospital database. CONCLUSIONS: The use of hospital administrative databases and probabilistic linkage methodology may represent a methodological alternative for the validation of reported utilization of health care services, but some strategies should be employed in order to minimize the problems related to the use of this methodology in non-ideal conditions. Ideally, a single identifier, such as a personal health insurance number, and the universal coverage of the database would be desirable.
