Characteristics of international primary care practices and physicians related to advance care planning: a cross-sectional survey study

BACKGROUND: Primary care providers (PCPs) are well-situated to delivery primary palliative care such as advance care planning (ACP). The aim of this work is to identify practice characteristics, including features found in advanced primary care models (APCMs), that predict PCP engagement of patients in ACP. METHODS: We analyzed characteristics of physician respondents and their practices associated with ACP conversations in older and sicker patients using data from 11 countries who participated in the 2015 Commonwealth Fund International Survey of Primary Care Physicians in 10 Nations. The primary outcome was how routinely these ACP conversations are reported. We used a validated measure to describe practice-level characteristics of advanced primary care models. We conducted bivariate and multivariable analyses to determine PCP and practice characteristics associated with routinely engaging patients in ACP and with documenting patient preferences in medical records. RESULTS: Respondents (N = 12,049) predominantly were older than 45 and did not view their jobs as high stress. PCPs reported routinely engaging patients in ACP work in practices with more APCM features. They are more likely to view their jobs as high stress, to work more hours, to practice in rural areas, and to work in smaller practices. Multivariable analyses showed that older PCP age, higher perceived stress of the job, practice location in rural areas, and increased number of APCM features were associated with more ACP conversations. Increased number of APCM features was also associated with higher odds of routinely recording patient preferences in their medical records. CONCLUSIONS: In this international survey, physician and practice characteristics, including having features associated with APCMs, were associated with whether physicians routinely discuss ACP with patients who are older and sicker. Many features of APCMs may facilitate ACP discussions between PCPs and patients. SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1186/s12875-023-02103-8.
