Contrast in Adjusted Patient Experience and Utilization at 12 Months Between Not Reassigned and Reassigned Patients
| Characteristic | Not Reassigned Estimate (CI) | Reassigned Estimate (CI) | Mean Differencea Estimate (CI) | PValue |
|---|---|---|---|---|
| CI = confidence interval. | ||||
| a Adjusted mean difference and P value from linear regression with cluster-adjusted standard errors. Comparisons are between reassigned and not reassigned patients, over 12-month patient experience measures adjusting for sex, age, educational attainment, self-reported health status at baseline, assignment to new vs existing physician, and 2006 patient experience. | ||||
| b 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. | ||||
| c Adjusted percent difference and P value from a generalized linear model with a log link and Poisson variance, adjusting for overdispersion. Comparisons are between reassigned and not reassigned patients, over 12-month utilization adjusting for sex, age, morbidity, duration of relationship with primary care physician, assignment to new vs existing physician and 2006 utilization. | ||||
