a

PCMH total and subscale scores are from a 0-100 scale created by the authors and based on survey responses of providers and staff at each clinic (see reference 12).

b

Patient experience is scored on a 0-100 (0 least, 100 most) scale and assessed by the Consumer Assessment of Healthcare Providers and Systems Clinician & Group (CAHPS-CG) Survey.

c

Estimate (95% confidence interval) is reported from multivariate generalized estimating equation models with the clinic clustering effect. The estimate indicates how much a 10-point increase in total PCMH score or PCMH subscale score would increase the patient experience.

d

Patient experience is modeled in two ways, once as a function of total PCMH score and covariates, and again as a function of the five PCMH subscales and covariates. Covariates were child age group, sex, race or ethnicity, type of insurance, number of clinic visits in the last 12 months, duration of relationship with provider, parents’ report of the child's health status, parent age group, parent education level, clinic full-time equivalent providers and the state in which the clinic is located.
