Trends and Disparities in the Distribution of Outpatient Physicians' Annual Face Time with Patients, 1979-2018

Physician time is a valuable yet finite resource. Whether such time is apportioned equitably among population subgroups, and how the provision of that time has changed in recent decades, is unclear.

To investigate trends and racial/ethnic disparities in the receipt of annual face time with physicians in the USA.

Repeated cross-sectional.

National Ambulatory Medical Care Survey, 1979-1981, 1985, 1989-2016, 2018.

Office-based physicians.

Exposures included race/ethnicity (White, Black, and Hispanic); age (<18, 18-64, and 65+); and survey year. Our main outcome was patients' annual visit face time with a physician; secondary outcomes include annual visit rates and mean visit duration.

Our sample included n=1,108,835 patient visits. From 1979 to 2018, annual outpatient physician face time per capita rose from 40.0 to 60.4 min, an increase driven by a rise in mean visit length and not in the number of visits. However, since 2005, mean annual face time with a primary care physician has fallen, a decline offset by rising time with specialists. Face time provided per physician changed little given growth in the physician workforce. A racial/ethnic gap in physician visit time present at the beginning of the study period widened over time. In 2014-2018, White individuals received 70.0 min of physician face time per year, vs. 52.4 among Black and 53.0 among Hispanic individuals. This disparity was driven by differences in visit rates, not mean visit length, and in the provision of specialist but not primary care.

Self-reported visit length.

Americans' annual face time with office-based physicians rose for three decades after 1979, yet is still allocated inequitably, particularly by specialists; meanwhile, time spent by Americans with primary care physicians is falling. These trends and disparities may adversely affect patient outcomes. Policy change is needed to assure better allocation of this resource.
