Improving efficiency through workflow optimization in a pharmacist-run diabetes clinic

Abstract

Abstract Purpose To evaluate the impact of hiring nonclinical support staff on pharmacist productivity and diabetes control outcomes in internal medicine clinics of an integrated healthcare system. Methods A retrospective, longitudinal cohort study was conducted. Patients were included if they were contacted by telephone for a diabetes consultation with a clinical pharmacist from July 1, 2015, through June 30, 2017. Nonclinical support staff were hired in July 2016 to schedule patient appointments with the clinical pharmacists. The primary outcome was the average rate of completed telephone encounters per month before and after hiring of nonclinical support staff. The secondary outcome was the mean change in glycated hemoglobin (HbA1c) level in patients who had a laboratory assay completed within 90 days of clinical pharmacist outreach. The tertiary outcome was the call completion rate for scheduled appointments vs unscheduled calls. Results In total, 6,709 patients were included; their average age was 55 years. After the intervention, the mean (SD) rate of completed telephone encounters increased from 61% (3.8%) to 77% (3.5%) (P < 0.001). Small improvements were noted in glycemic control, as measured by the mean (SD) percentage of patients with an HbA1c concentration of <8%, which increased from 31% (5.2%) to 42% (3.0%) (P < 0.001), and the mean (SD) change in average HbA1c concentration, which increased from 8.9% (0.2%) to 8.5% (0.1%) (P < 0.001). Throughout the study, scheduled calls were more likely to be completed than unscheduled calls (mean [SD] completion rate, 66% [9.0%] vs 74% [6.0%]; P < 0.001). Conclusion Hiring nonclinical support staff led to greater efficiency among the clinical pharmacist team, yielding a higher volume of telephone interactions, a modest overall decrease in HbA1c values, and an increased likelihood of reaching patients by phone.
