Primary care doctors are becoming more scarce. The vacuum may be filled by pharmacists, and as part of health care reform, multidisciplinary teams are being assessed. The purpose of this research was to ascertain if diabetes outcomes would be improved by including a pharmacist in an interprofessional health team. Medicaid-eligible diabetic patients were randomized to receive standard treatment (control arm) or standard care plus pharmacist care (intervention arm) for a 12-month period (phase 1) in this two-phase pilot trial. The change in glycated hemoglobin (A1C) from baseline was the main result. Medication treatment problems (MTPs) for comorbid diseases, adherence to preventive care visits, health care usage, self-rated health, and satisfaction surveys were examples of secondary outcomes. Patients in the control group who failed to reach an A1C of less than 8% at the end of phase 1 were eligible to enter phase 2, where they were treated by a pharmacist for six months. 122 of the 239 patients that were recruited completed phase 1. The mean A1C for intervention patients was 1.85 percentage points (pp) lower than baseline at 12 months, whereas the control group's was 0.94 pp (between-group difference 0.91 pp; P ¼ 0.0218). The majority of phase 1 and phase 2 control patients (79%) had an improvement in their A1C of more than 1 pp (P < 0.01). After 806 patient visits, the pharmacists found 2638 MTPs. Preventive care appointments with nutrition (P ¼ 0.043), ophthalmology (P ¼ 0.002), and dental (P ¼ 0.007) were more often attended by intervention patients. While 37% of control patients thought their experience with their physician was great, 78% of intervention patients thought their experience with the pharmacist was outstanding. Comanagement of diabetic patients by pharmacists may greatly enhance patient satisfaction and glucose control. Pharmacists were included into the interprofessional patient care team via innovative payment methods.
