Comparison of 2 Population Health Management Approaches to Increase Vitamin B12 Monitoring in Patients Taking Metformin.
Annals of Pharmacotherapy 2016 October
BACKGROUND: Population health management uses proactive, targeted interventions to improve health outcomes.
OBJECTIVES: To compare the effectiveness of and time required for 2 pharmacist-driven population health management interventions to improve vitamin B12 monitoring in patients taking metformin.
METHODS: Physicians were randomized to 1 of 2 population health management interventions. For all patients of physicians assigned to the patient portal intervention, a pharmacist communicated need for vitamin B12 monitoring directly to the patient using an electronic patient portal. For all patients of physicians assigned to the office visit intervention, a pharmacist communicated monitoring recommendations to the physician prior to a scheduled office visit through the electronic health record. The proportion of patients in each group who received vitamin B12 monitoring 30 days after the intervention was quantified.
RESULTS: A total of 489 patients of 26 physicians within 5 general internal medicine clinics who had taken metformin for at least 1 year and had not received vitamin B12 monitoring within the past year were identified. The intervention delivered as part of an office visit resulted in increased serum vitamin B12 monitoring compared with the intervention using electronic communication through a patient portal (odds ratio = 4.05; 95% CI = 1.22, 13.46; P = 0.03). The office visit intervention and the patient portal intervention took an average of 8.2 and 0.9 minutes per patient, respectively.
CONCLUSIONS: Population health management completed during the course of office visits was more effective at increasing vitamin B12 monitoring and required more time than an intervention delivered through an electronic patient portal.
