Racial disparities in the process and outcome of health care may be partial
ly explained by differences in time use during outpatient visits by African
-American and white patients. This study was undertaken to determine whethe
r physicians use their time in clinical encounters with African-American pa
tients differently than with white patients. This study was a multimethod,
cross-sectional study conducted between October 1994 and August 1995 in 84
family practices in northeast Ohio. Participants were 4,352 white and Afric
an-American outpatients visiting 138 physicians.
Time use during the patient visit was measured by the Davis Observation Cod
e, which categorizes every 20-second interval into 20 different behavioral
categories. Among 3,743 white and 509 African-American patients, after adju
stment for potential confounders, visits by African-American patients were
slightly longer than visits with white patients (10.7 vs. 10.1 minutes, p =
0.027). After further adjustment for multiple comparisons, physicians spen
t a lower proportion of time intervals with African-American patients as co
mpared to white patients planning treatment (29.0% vs. 32.1%, p < 0.001), p
roviding health education (16.4% vs. 19.7%, p < 0.001), chatting (5.2% vs.
7.6%, p < 0.001), assessing patients' health knowledge (0.8% vs. 1.2%, p <
0.001), and answering questions (5.8% vs. 6.9%, p = 0.002). Physicians spen
t relatively more time intervals with African-American patients discussing
what is to be accomplished (9.3% vs. 7.6%, p < 0.001) and providing substan
ce use assessment and advice (0.8% vs. 0.4%, p = 0.001). In conclusion, phy
sicians spend time differently with African-American as compared with white
patients. These differences may represent appropriate tailoring of service
s to meet unique needs, but could also represent racial bias.
