Medication Regimen Complexity in Patients Receiving Consultant Pharmacy Services in Home Health Care.

An interprofessional, team-based approach has become common in a variety of settings. However, consultant pharmacist participation in home health care (HHC) has been limited. To evaluate a potential need for pharmacists in HHC, the objective of this project was to document the medication complexity of patients seen by an established HHC consultant pharmacist service. This retrospective review reports on medication regimen complexity in 79 patients receiving this service using the Patient-Level Medication Regimen Complexity Index (MRCI) tool. The average MRCI score was 30 (± 15 standard deviation), suggesting a high level of medication regimen complexity in this population. High scores have been correlated with increased potential adverse drug events, 30-day hospital readmissions, and reduced adherence. Further research is needed for both the utilization of consultant pharmacists in HHC and the use of MRCI in identifying HHC patients needing pharmacist services.
