Notes: ACES-SF = Ambulatory Care Experiences Survey—Short Form; PACIC = Patient Assessment of Chronic Illness Care Survey; QI = quality of doctor–patient interactions; SDM = shared decision making; CC = coordination of care; AC = access to care; HO = helpfulness of office staff; PA = patient activation/involvement; and GS = goal setting/tailoring.
The ACES-SF and PACIC questions (scored on 6- and 5-point Likert scales, respectively) were totaled within the subscales and then transformed to 100-point summary scores.
Adjusted mean difference and p value from generalized linear estimating equation regressions comparing average 12- and 24-month scores adjusting for age, educational attainment, self-reported health status at baseline, and baseline patient experience between the PCMH and the control clinics.
