Figure 1: Adjusted odds ratios (ORs) of after-hours visits among patients whose physicians were reimbursed through a blended capitation model compared with patients whose physicians were reimbursed through an enhanced fee-for-service model. Adjustments were made for the physician and patient characteristics listed in the figure. Values less than 1.0 indicate fewer after-hours visits in the capitation model than in the enhanced fee-for-service model. CI = confidence interval. *Resource Utilization Bands categorize patients according to their morbidity and corresponding expected use of health care resources; they range from 0 (lowest expected health care costs) to 5 (highest expected health care costs). †Aggregated Diagnosis Groups indicate a patient’s level of comorbidity, ranging from 0 (no diagnosis group) to ≥ 10 (at least 10 distinct diagnosis groups).
Figure 2: Adjusted odds ratios (ORs) of use of emergency department visits among patients whose physicians were reimbursed through a blended capitation model compared with patients whose physicians were reimbursed through an enhanced fee-for-service model. Adjustments were made for the physician and patient characteristics listed in the figure. Values greater than 1.0 indicate more visits to an emergency department in the capitation model than in the enhanced fee-for service model. CI = confidence interval. *See caption of Figure 1 for explanations of Resource Utilization Bands and Aggregated Diagnosis Groups.
