Comparative research aspects on hospitalizations for ambulatory care sensitive conditions: the case of Brazil and Portugal / Aspectos de pesquisa comparativa em internações por condições sensíveis à atenção primária: o caso de Brasil e Portugal

Abstract Hospitalizations for ambulatory care sensitive conditions have been used to measure access, quality and performance of the primary health care delivery system, as timely and adequate care could potentially avoid the need of hospitalization. Comparative research provides the opportunity for cross-country learning process. Brazil and Portugal have reformed their primary health care services in the last years, with similar organizational characteristics. We used hospitalization data of Brazil and Portugal for the year 2015 to compare hospitalizations for ambulatory care sensitive conditions between the two countries, and discussed conceptual and methodological aspects to be taken into consideration in the comparative approach. Brazil and Portugal presented similarities in causes and standardized rates of hospitalizations for ambulatory care sensitive conditions. There was great sensitivity on rates according to the methodology employed to define conditions. Hospitalizations for ambulatory care sensitive conditions are important sources of pressure for both Brazil and Portugal, and there are conceptual and methodological aspects that are critical to render the country-comparison approach useful.

Resumo As internações por condições sensíveis à atenção primária têm sido usadas para medir o acesso, a qualidade e o desempenho da atenção primária à saúde, uma vez que o atendimento oportuno e adequado poderia evitar a necessidade de internação. A pesquisa comparativa oferece oportunidade para o processo de aprendizagem entre países. Brasil e Portugal reformaram seus serviços de atenção primária à saúde nos últimos anos, com características organizacionais semelhantes. Utilizamos dados de internação do Brasil e de Portugal para o ano de 2015 para comparar internações por condições sensíveis à atenção primária entre os dois países, e discutimos aspectos conceituais e metodológicos a serem considerados na abordagem comparativa. Brasil e Portugal apresentaram semelhanças nas causas e taxas padronizadas de internações por condições sensíveis à atenção primária. Houve grande sensibilidade nas taxas de acordo com a metodologia empregada para definir as condições. Internações por condições sensíveis à atenção primária são importantes fontes de pressão tanto para o Brasil quanto para Portugal, e há aspectos conceituais e metodológicos que são fundamentais para tornar a abordagem comparativa entre países útil.

Performance Verification of Chemiluminesent Micropaticle Immunoassay for the Four Blood Index / 现代检验医学杂志

Objective To evaluate the analytical performance of ARCHITECT-i2000SR chemiluminescence analyzer in detec-tion of HBsAg,HIV-antibody,TP-antibody and HCV-antibody.Methods Validated the precision,carryover,ference interval of alpha-fetoprotein and linearity performance of ARCHITECT-i2000SR.The same specimens were tested by both CMIA and ELISA,and the results were compared and analyzed.Results The precision,carryover and ference interval of alpha-feto-protein of HBsAg,HIV-antibody,TP-antibody and HCV-antibody were within the range provided by the manufacturer for ARCHITECT-i2000SR.The theoretical and measured values of HBsAg were:Y = 1.102X - 6.678 6 (r = 0.995 5,P <0.05),the range of linearity 1.08~208.6.The sesult was very good for the four blood index by both methods.Conclusion The basic performances of ARCHITECT-i2000SR were consistent with the data provided by the manufacturer,so it canbe used to inspect the clinical samples and the sasults were credible.
