Properties of a short questionnaire for assessing Primary Care experiences for children in a population survey

<p>Abstract</p> <p>Background</p> <p>The Primary Care Assessment Tool (PCAT) is an interesting set of tools for primary care research. A very short version could inform policy makers about consumer experiences with primary care (PC) through health surveys. This work aimed to investigate the validity and reliability of a selection of items from the child short edition (CS) of the PCAT.</p> <p>Methods</p> <p>A 24 item questionnaire permitted the identification of a regular source of care and the assessment of the key attributes of first contact, ongoing care over time, coordination, services available and services received (comprehensiveness), and cultural competence. Structural validity, reliability, and construct validity were assessed using responses from 2,200 parents of a representative sample of the population aged 0 to 14 years in Catalonia (Spain) who participated in the 2006 Health Survey. Structural validity was analyzed using exploratory and confirmatory factor analyses and reliability was assessed using Cronbach's alpha. Construct validity was assessed using linear regression analysis between PC experience scores and a measure of overall user satisfaction with healthcare services.</p> <p>Results</p> <p>A total of 2,095 (95.2%) parents provided useable responses on PC. After Confirmatory Factor Analysis (CFA), the best fitting model was a 5-factor model in which the original dimensions of first contact and ongoing care were collapsed into one. The CFA also showed a second order factor onto which all domains except services available loaded (root mean square error of approximation = 0.000; comparative fit index = 1.00). Cronbach's alpha values for one of the original scales (first-contact) was poor (alpha < 0.50), but improved using the modified factor structure (alpha > 0.70). Scores on the scales were correlated with satisfaction with healthcare services (p < 0.01), thereby providing some preliminary evidence of construct validity.</p> <p>Conclusions</p> <p>This very short questionnaire obtained from the PCAT-CE yields information about five attributes of PC and a summary score. It has shown evidence of validity and reliability for judgments about experiences with primary care overall. If space on surveys is at a premium, the instrument could be useful as a measure of PC experiences.</p

Limited Effect of Dietary Saturated Fat on Plasma Saturated Fat in the Context of a Low Carbohydrate Diet

We recently showed that a hypocaloric carbohydrate restricted diet (CRD) had two striking effects: (1) a reduction in plasma saturated fatty acids (SFA) despite higher intake than a low fat diet, and (2) a decrease in inflammation despite a significant increase in arachidonic acid (ARA). Here we extend these findings in 8 weight stable men who were fed two 6-week CRD (12%en carbohydrate) varying in quality of fat. One CRD emphasized SFA (CRD-SFA, 86 g/d SFA) and the other, unsaturated fat (CRD-UFA, 47 g SFA/d). All foods were provided to subjects. Both CRD decreased serum triacylglycerol (TAG) and insulin, and increased LDL-C particle size. The CRD-UFA significantly decreased plasma TAG SFA (27.48 ± 2.89 mol%) compared to baseline (31.06 ± 4.26 mol%). Plasma TAG SFA, however, remained unchanged in the CRD-SFA (33.14 ± 3.49 mol%) despite a doubling in SFA intake. Both CRD significantly reduced plasma palmitoleic acid (16:1n-7) indicating decreased de novo lipogenesis. CRD-SFA significantly increased plasma phospholipid ARA content, while CRD-UFA significantly increased EPA and DHA. Urine 8-iso PGF2α, a free radical-catalyzed product of ARA, was significantly lower than baseline following CRD-UFA (−32%). There was a significant inverse correlation between changes in urine 8-iso PGF2α and PL ARA on both CRD (r = −0.82 CRD-SFA; r = −0.62 CRD-UFA). These findings are consistent with the concept that dietary saturated fat is efficiently metabolized in the presence of low carbohydrate, and that a CRD results in better preservation of plasma ARA

Influência de fatores estruturais e organizacionais no desempenho da atenção primária à saúde em Belo Horizonte, Minas Gerais, Brasil, na avaliação de gestores e enfermeiros

O objetivo do trabalho foi avaliar o desempenho da atenção primária à saúde (APS) em Belo Horizonte, Minas Gerais, Brasil, utilizando o questionário PCATool entre enfermeiros das equipes de saúde da família e gerentes. O escore total da APS foi 0,75 (bom); o primeiro contato (0,95), a longitudinalidade (0,83), a integralidade (0,83) e a coordenação (0,78) apresentaram melhor desempenho. O enfoque familiar, a orientação comunitária e o acesso receberam as piores pontuações (0,68, 0,56 e 0,45). Os fatores associados (p < 0,05) à melhor performance da APS foram: disponibilidade de equipamentos e outros insumos (RP ajustada = 1,57), formação dos profissionais em saúde da família (RP = 1,44), presença do médico por mais de 30 horas semanais (RP = 1,42) e quatro ou mais equipes por unidade básica de saúde (RP = 1,09). Os resultados revelaram a importância de fatores estruturais (sistemas logísticos adequados, formação da equipe em saúde da família) e organizacionais (médico em tempo integral, número de equipes da Estratégia Saúde da Família por unidades básicas de saúde) na performance da APS e na melhoria da qualidade

Internal consistency and reliability of Primary Care Assessment Tool (PCATool-Brasil) for child health services

Health strategies based on primary health care have been expanding in Brazil. An instrument applied to users, the Primary Care Assessment Tool (the PCATool), which measures the extent of primary care, has been validated in the United States. We sought to adapt the PCATool to Brazil and analyze its validation and reliability through a cross-sectional validation study of the Child PCATool.Validation included: translation, back-translation, adaptation, debriefing, content and construct validate, internal consistency, and reliability analysis. The questionnaire was applied to 468 parents or guardians of children registered with 18 primary health services in Porto Alegre, representing the services’ normal pediatric population. Using factor analysis, 8 domains were identified, with Cronbach’s α ranging from 0.74 to 0.88.Validation resulted in a 45-item scale, divided into 8 attributes (Access to First Contact, Continuity, Coordination, 3 attributes of Comprehensiveness, Community Orientation, and Family Orientation). These results showed that the PCATool-Brasil has adequate validity and reliability and could be used as a national instrument to evaluate primary health care after its application to other population settings in the country.Fundação de Amparo à Pesquisa, Estado do Rio Grande do Sul e Escola de Saúde Pública, Rio Grande do Su
