Effect of a Pharmacist-Driven Medication Management Intervention Among Older Adults in an Inpatient Setting

摘要

BackgroundOlder adults have a seven times greater risk than younger adults of being hospitalized due to an adverse drug event.ObjectiveThe objective of this study was to compare the number of potentially inappropriate medications (PIMs) on admission to the number of PIMs on discharge following pharmacist intervention.Patients and MethodsThis was a prospective, single-center pilot study performed at a tertiary medical center. Eighty-two adults aged 65years or older on five or more medications who were admitted to the general medicine floor between December 2016 and May 2017 were included in the analysis. Pharmacists completed a review of prior admission medications and identified PIMs. Recommendations for PIMs were communicated to the medical team and documented in the patient's electronic medical record. PIMs were measured by the use of validated screening tools and an assessment of patient-specific parameters.ResultsFifty-two percent of our patients were taking at least one PIM. The average number of PIMs on admission was found to be 0.841.12. Pharmacist intervention resulted in a statistically significant reduction to an average of 0.56 +/- 0.91 PIMs (P<0.01). The mean time to complete the medication therapy management (MTM) process was 49.39 +/- 16.2min per patient.Conclusion While pharmacist-driven MTM significantly reduced PIMs in our study, the implementation of this model in the inpatient setting faces several challenges.
