Still no differences in the length or scope of primary and ambulatory care for Medicaid and commercial patients.

Abstract

Many seek to improve the quality of primary care in the United States, particularly for Medicaid patients. This paper revisits the question of whether Medicaid patients receive less primary care, such as the length or scope of services per visit, than commercial patients. Analyses of 2016-2019 National Ambulatory Medical Care Survey data, the most recent available, find there were no significant differences in the average length of ambulatory care visits, or of primary care visits in particular, between Medicaid and commercial care, nor differences in the scope, based on the number of diagnostic and treatment services, health education topics covered, or the number of medications prescribed in the visit. Only small differences were found for uninsured patients. The duration and scope of ambulatory and primary care visits were primarily related to the characteristics of patients, visits, and the physicians' practices. To improve primary and ambulatory care for disadvantaged patients, it may be more important to focus on increasing access to care by reducing insurance and cost-related barriers and on broad-based efforts to improve quality.
