Community health center (CHC) clinics were limited to 431 clinics from 132 community health centers on OCHIN electronic health records by January 1, 2019. Patient sample size for each service was determined by the number of patients in the specified age and sex category with a primary care visit between January 1, 2019, and March 31, 2020. Rates of monthly delivery and CIs were determined by generalized estimating equation models of monthly service counts specifying a Poisson distribution, a log link, and an offset equal to log(patient sample size/ adult_1000). We adjusted for within–health system correlation using robust sandwich estimators.
Excludes visits coded as mental or behavioral health visits. Medical professionals were defined as physicians, advanced practice clinicians, or registered nurses. Patient sample size was 768 810 adult patients with primary care visits aged 19 to 79 years.
Includes all visits by patients younger than 18 years with preventive care evaluation and management codes or diagnosis codes indicating well-child visits (n = 289 117 children with primary care visits).
Resulted papanicolaou tests for women aged 21 to 65 years (n = 354 911 women with primary care visits).
Resulted hemoglobin A1c tests in patients with diabetes aged 21 to 79 years (n = 107 100 patients with diabetes and primary care visits).
Mammogram orders in women aged 50 to 70 years (n = 134 627 women with primary care visits).
