Trends in the quality of child health care in the first week of life in primary care services in Brazil.

The aim of this study was to assess temporal trends in the quality of health care during the first-week child check-up in primary care services stratified by municipal, health team and maternal characteristics. We conducted a cross-sectional study using data from the three cycles of the National Program for the Improvement of Access and Quality (PMAQ) (2012, 2014 and 2018). Adult service users with children aged up to 2 were interviewed. The outcome was "good quality health care in the first week of life". Descriptive and time trend analyses were performed using variance-weighted least squares regression. The frequency of good quality care during the first-week check-up was 47.9% (95%CI 46.6-49.3) in 2012, 52.5% (95%CI 51.3-53.7) in 2014 and 53.3% (95%CI 52.2-54.4) in 2018, with an annual increase of 0.73 pp (p<0.001). The annual increase was greater in the Northeast (2.06 pp) and in municipalities with very low/low HDI (1.48 pp) and 100% family health strategy coverage (0.98 pp). Trends in the frequency of good quality health care during the first-week child check-up were favorable.
