Background:: Medication therapy management (MTM) may be optimized if pharmacists engaged in health information exchange (HIE) by reviewing unedited medical records.
Methods:: In this nonblinded, randomized, controlled pilot, pharmacists delivered a part of MTM, comprehensive medication reviews (CMRs), to adult patients in a practice-based research network (PBRN). Intervention community pharmacists solicited the last 6 months of patients' primary care provider-held, unedited medical records. The primary and secondary outcomes were the number of medication-related problems (MRPs) and preventive care omissions identified. The intervention was analyzed via Mann-Whitney U test and multivariate linear regression models. Pharmacists were surveyed regarding the available health history's helpfulness in CMR delivery.
Results:: Thirty-seven patients received CMRs across the 2 groups. Intervention pharmacists (n = 4) identified significantly more MRPs (median = 11 vs 6; B = 6.98, 95% confidence interval [CI]: 0.005-13.96; P = .049) and omissions in preventive care (24% vs 17%; B = 2.78, 95% CI: 0.46-5.10; P = .009) than usual care pharmacists (n = 3). Intervention pharmacists were more likely to agree they were confident they identified all of the patient's MRPs (47.1% vs 15.8%), but neither group was more likely than the other to believe they had resolved all MRPs (41.2% vs 42.1%). Finally, intervention pharmacists agreed 100% of the time that the available health history helped them complete a better CMR, compared with only 69% of usual care pharmacists.
Conclusion:: In this pilot, community pharmacists identified more MRPs and omissions in preventive care when they reviewed unedited medical records. Larger studies are warranted to determine whether HIE can improve outcomes.
