BP = blood pressure; CQM = clinical quality measure; EOV = educational outreach visit; FQHC = Federally Qualified Health Center; IHS = Indian Health Service; IQR = interquartile range; ORPRN = Oregon Rural Practice Research Network; PF = practice facilitation; QI = quality improvement; SL = shared learning.
Notes: Missing data on practice characteristics: panel size not reported for 30 practices that did not empanel patients, missing for 16 other practices; patient visits/week, 1 practice; centralized QI, 2 practices; prior experience customizing data, 5 practices; prioritization of QI work, 5 practices. Missing data on patient population: race, 65 practices; Hispanic ethnicity, 72 practices; female sex, 53 practices; age, 64 practices; insurance type, 45 practices. Missing data on baseline BP CQM: 17 practices.
↵a Goal is ≥70% of patients with history of hypertension achieving BP <140/90 mm Hg.
