To assess the reliability of data in electronic health records (s) for measuring processes of care among primary care physicians (s) and examine the relationship between these measures and clinical outcomes.

Data Sources/Study Setting

data from 15,370 patients with diabetes, 49,561 with hypertension, in a group practice serving four orthern alifornia counties.

Study Design/Methods

Exploratory factor analysis () and multilevel analyses of the relationships between processes of care variables and factor scales with control of hemoglobin A1c, blood pressure (), and low density lipoprotein () among patients with diabetes and among patients with hypertension.

Principal Findings

Volume of e‐messages, number of days to the third‐next‐available appointment, and team communication emerged as reliable factors of processes of care in (Cronbach's alpha = 0.73, 0.62, and 0.91). Volume of e‐messages was associated with higher odds of control (≤100) ( = 1.13,  < .05) among patients with diabetes. Frequent in‐person visits were associated with better ( = 1.02,  < .01) and control ( = 1.01,  < .01) among patients with diabetes, and better control ( = 1.04,  < .01) among patients with hypertension.


The offers process of care measures which can augment patient‐reported measures of patient‐centeredness. Two of them are significantly associated with clinical outcomes. Future research should examine their association with additional outcomes.
