  1. aNumber of patients based on patient’s last visit
  2. bIncludes both Hispanic and non-Hispanic African American/Black and Whites
  3. cPatients residing in rural areas was determined using patient’s zip code corresponding to RUCC code (4–9)
  4. dOverweight or obese categories derived from BMI is calculated as the maximum recorded BMI across the study period per patient If BMI was not available, the patient’s height and maximum weight across the study period were used to calculate BMI using the standard formula (weight (kg) / height (cm) / height (cm)] × 10,000)
  5. eHypertension medications were the total prescribed across the study period per patient. Medications were identified using the HEDIS reference list for hypertension medications [28] and reviewed with two physicians boarded in internal medicine prior to making calculations
  6. fComorbidities calculated as mode of Elixhauser Comorbidity Index across the study period per patient. The index was calculated using the Healthcare Cost and Utilization Project Methods Series Comorbidity Software. The comorbidity index is a total sum of diagnosed chronic disease comorbidities found in 31 categories defined in the software [21].
  7. gPatients with controlled hypertension (≤ 140 mm Hg SBP and ≤ 90 mm Hg DBP) per the National Committee for Quality Assurance (NCQA) quality measure for “Controlling High Blood Pressure” [22] were flagged (yes/no). BP was calculated at the patients’ first visit and annually based on the last measured BP in the calendar year
