Complex healthcare needs can be met through effective interprofessional collaboration. Since 2014, Swedish Child Healthcare Services (CHS) include universal team-based visits with a nurse and a physician who perform such visits at the age of 4 weeks, 6 months, 12 months, and 2.5 to 3 years, as well as targeted team-based visits to address additional needs. The aim of this study was to describe the prevalence of team-based visits in the Swedish CHS and possible associations between team-based visits and contextual factors that may affect its implementation. A national cross-sectional survey was conducted using a web-based questionnaire distributed to all reachable nurses, physicians, and psychologists (n =3,552) engaged in the CHS. Data were analyzed using descriptive statistics and binary and multivariate logistic regressions. The response rate was 32%. Team-based visits were reported by 82% of the respondents. For nurses and physicians, the most frequent indication was specific ages, while for psychologists it was to provide parental support. Respondents working at Family Centers were more likely to perform team-based visits in general, at 2.5 to 3 years and in case of additional needs, compared to respondents working at Child Health Centers (CHC) and other workplaces. In conclusion, team-based visits are well implemented, but the pattern differs depending on the contextual factors. Targeted team-based visits and team-based visits at the age of 2.5 to 3 years are most unequally implemented.
