Purpose: Although optimizing pharmacotherapy for community-dwelling older adults is important, it is unclear whether interventions by interdisciplinary teams improve polypharmacy, frailty, or other health outcomes when reviewing patient prescriptions.
Methods: We conducted a systematic review to evaluate the efficacy of interdisciplinary team interventions in community-dwelling older adults. PubMed, CINAHL with Full Text, CENTRAL, Embase, and gray literature were systematically searched to identify articles. The selection criteria included the following: 1) age ≥65 years, 2) intervention by interdisciplinary teams (physicians, nurses, and pharmacists), and 3) randomized controlled trials.
Results: A total of 579 articles were identified, and five articles met the inclusion criteria. Meta-analysis was not conducted because of the different outcome measures of the studies. The studies showed that polypharmacy is prevalent among community-dwelling older adults. Additionally, while intervention by interdisciplinary teams reduced the number of drugs administered, it did not improve frailty, ADL, QOL, or other health outcomes. No study has evaluated the complexity of medication regimens (e.g., one-dose packaging).
Conclusions: This systematic review revealed that studies of pharmacotherapy in community-dwelling older adults have not been adequately conducted. Appropriate pharmacotherapy is important; therefore, further studies are needed in the future.
