Patients in the United States have significant autonomy when choosing their primary care physician, and he population of physicians has become more diverse, with increasing female providers and providers of different races. Most studies investigating patient preferences for gender of their PCP are based on self-reported data and indicate that female patients are more often than males to have a same-gender preference for their PCP. Because self-reported preferences may not reflect true preferences, we analyzed objective data to determine patients’ preferences for PCP’s gender. Our data indicated that both male and female patients are more-likely to request and see a same-gender PCP, and this preference is more pronounced in males than females.
