          Abstract

          Summary Objective: This study describes the summary scores of the Short Form-12 (SF-12) questionnaire, according to socio-demographic factors obtained in a probabilistic and representative sample of the Brazilian urban population. Method: Five thousand (5,000) individuals, over the age of 15, were assessed in 16 capital cities, in the five regions of the country. The selection of households was random. Face-to-face approach was applied in the household interviews. The SF-12 questionnaire was used to assess quality of life. Demographic and socioeconomic characteristics were also evaluated: gender, age, marital status, skin color, region of the country and use of the public health service. Results: The mean value (SD) of the SF-12 for the entire population was 49.3 (8.7) for the physical component (PCS-12) and 52.7 (9.7) for the mental component (MCS-12). Statistical differences were found for gender (PCS-12 and MCS-12), age (PCS-12) and working status (PCS-12 and MCS-12). Women, elderly, widowed and unemployed individuals, those with lower income and with complaints in the last seven days showed lower mean values (PCS-12 and MCS-12). Conclusion: From this point forward, we can provide the basis for comparisons with future research that use the SF-12 for quality of life assessment in Brazil. The Brazilian population has a lower degree of quality of life related do the physical component, and the SF-12 is a useful and discriminative instrument for assessing quality of life in different socio-demographic groups.

          Resumo Objetivo: Este estudo descreve os escores sumários do questionário Short Form-12 (SF-12), de acordo com os fatores sociodemográficos obtidos em uma amostra probabilística e representativa da população urbana brasileira. Método: Cinco mil (5.000) indivíduos, com idade superior a 15 anos, foram avaliados nas cinco regiões do país, em 16 capitais. A seleção dos domicílios foi aleatória. A coleta de dados foi realizada através de entrevistas domiciliares. O questionário SF-12 foi utilizado para a avaliação de qualidade de vida. Características demográficas e socioeconômicas também foram avaliadas: sexo, idade, estado civil, cor da pele, região do país e uso do serviço público de saúde. Resultados: O valor médio (DP) do SF-12 para a população total foi de 49,3 (8,7) para o componente físico (PCS-12) e 52,7 (9,7) para o componente mental (MCS-12). Foram encontradas diferenças estatísticas para sexo (PCS-12 e MCS-12), idade (PCS-12) e estado laboral (PCS-12 e MCS-12). Mulheres, idosos, viúvos, indivíduos que não estavam trabalhando, pessoas com menor renda e queixas nos últimos sete dias apresentaram valores médios mais baixos (PCS-12 e MCS-12). Conclusão: Os resultados apresentados fornecem bases populacionais para comparações com pesquisas futuras que utilizem o SF-12 para a avaliação da qualidade de vida no Brasil. A população brasileira tem um menor grau de qualidade de vida relacionada ao componente físico, e o SF-12 é um instrumento útil e discriminativo para a avaliação de qualidade de vida em diferentes grupos sociodemográficos.

            Prevalence of rheumatic diseases in Brazil: a study using the COPCORD approach.

            To estimate the prevalence of rheumatic diseases in residents of Montes Claros, Brazil, of both sexes, aged above 16 years, using the COPCORD questionnaire. This was a cross-sectional study of 3038 people; the sample was probabilistic, by conglomerates, multiple stages, within homogeneous strata, the sampling unit being the domicile. The COPCORD questionnaire was used for all subjects, and a rheumatologist evaluated those patients who presented pain and/or functional disability. Laboratory tests and radiographs of small and large joints were done in some patients to confirm the diagnosis. Subjects were identified by socioeconomic level in quintiles A, B, C, D, and E, A being the highest. Two hundred nineteen patients were identified with rheumatic diseases, mean age 37 (SD 27) years, with female predominance. Seventy-seven (35.2%) were unemployed and socioeconomic level D was the most prevalent. Of all patients with rheumatic disease, osteoarthritis (OA) was observed in 126 (57.5%) patients, fibromyalgia (FM) in 76 (34.7%), rheumatoid arthritis (RA) in 14 (6.4%), and lupus in 3 (1.4%). Women were predominant in all diseases except OA. The mean (SD) age was 56 (12.7) years for OA, 43.2 (9.1) for FM, 53.4 (13.9) for RA, and 40 (14) for lupus. The prevalence of rheumatic diseases evaluated by the COPCORD questionnaire was 4.14% for OA, 2.5% for FM, 0.46% for RA, and 0.098% for lupus.

              Quality of life instruments for economic evaluations in health and social care for older people: a systematic review.

              Gaining health may not be the main goal of healthcare services aimed at older people, which may (also) seek to improve wellbeing. This emphasizes the need of finding appropriate outcome measures for economic evaluation of such services, particularly in long-term care, capturing more than only health-related quality of life (HrQol). This review assesses the usefulness of HrQol and wellbeing instruments for economic evaluations specifically aimed at older people, focusing on generic and preference-based questionnaires measuring wellbeing in particular. We systematically searched six databases and extracted instruments used to assess HrQol and wellbeing outcomes. Instruments were compared based on their usefulness for economic evaluation of services aimed at older people (dimensions measured, availability of utility scores, extent of validation). We identified 487 articles using 34 generic instruments: 22 wellbeing (two of which were preference-based) and 11 HrQol instruments. While standard HrQol instruments measure physical, social and psychological dimensions, wellbeing instruments contain additional dimensions such as purpose in life and achievement, security, and freedom. We found four promising wellbeing instruments for inclusion in economic evaluation: Ferrans and Powers QLI and the WHO-Qol OLD, ICECAP-O and the ASCOT. Ferrans and Powers QLI and the WHO-Qol OLD are widely validated but lack preference-weights while for ICECAP-O and the ASCOT preference-weights are available, but are less widely validated. Until preference-weights are available for the first two instruments, the ICECAP-O and the ASCOT currently appear to be the most useful instruments for economic evaluations in services aimed at older people. Their limitations are that (1) health dimensions may be captured only partially and (2) the instruments require further validation. Therefore, we currently recommend using the ICECAP-O or the ASCOT alongside the EQ-5D or SF-6D when evaluating interventions aimed at older people.
