Receipt of primary care in adults is associated with significantly more high-value care, slightly more low-value care, and better health care experience compared to those without primary care. This according to a nationally representative survey study of US adults aged ≥18 years who participated in the Medical Expenditure Panel Survey. Propensity score-weighted quality and experience or care were compared between 49,286 US adults with and 21,133 adults without primary care from 2012 to 2014. Researchers found:

• From 2002 to 2014, the mean annual survey response rate was 58%.
• Compared to those without primary care, those with primary care were older, more often females, and predominantly white individuals.

• US adults with primary care received significantly more high-value care and reported significantly better health access and experience vs those without primary care.
• Differences were stable from 2002 to 2014.
