"Pharming out" support: a promising approach to integrating clinical pharmacists into established primary care medical home practices.

Objective Embedding clinical pharmacists into ambulatory care settings needs to be assessed in the context of established medical home models. Methods A retrospective, observational study examined the effectiveness of the Intermountain Healthcare Collaborative Pharmacist Support Services (CPSS) program from 2012-2015 among adult patients diagnosed with diabetes mellitus (DM) and/or high blood pressure (HBP). Patients who attended this program were considered the intervention (CPSS) cohort. These patients were matched using propensity scores with a reference group (no-CPSS cohort) to determine the effect of achieving disease management goals and time to achievement. Results A total of 17,684 patients had an in-person office visit with their provider and 359 received CPSS (the matched no-CPSS cohort included 999 patients). CPSS patients were 93% more likely to achieve a blood pressure goal<140/90mmHg, 57% more likely to achieve HbA1c values<8%, and 87% more likely to achieve both disease management goals compared with the reference group. Time to goal achievement demonstrated increasing separation between the study cohorts across the entire study period (P<.001), and specifically, at 180 days post-intervention (HBP: 48% vs 27% P<.001 and DM: 39% vs 30%, P<.05). Conclusions CPSS participation is associated with significant improvement in achievement of disease management goals, time to achievement, and increased ambulatory encounters compared with the matched no-CPSS cohort.
