Deprescribing using the guidelines for medical treatment and its safety in the elderly and changes in patient qol and activities of daily living

Pharmacists applied deprescribing, which is a process for the rational use of drugs, for 13 at-home patients. The standard used for the rational use of drugs was the ``Guidelines for Medical Treatment and Its Safety in the Elderly'' (the Guidelines). The results of the deprescribing were discussed with physicians to determine prescriptions. After the prescription change, activities of daily living (ADL) and QOL were assessed using the Barthel Index and SF-36v2, respectively. Potentially inappropriate medications (PIMs) were detected in 10 of the 13 patients (76.9％). This detection rate is higher than previous PIM detection rates of 48.4％ and 40.4％ reported in prescriptions for home-care patients in Japan under the Beers and STOPP/START criteria. The Guidelines appeared useful as a decision support tool for deprescribing. The patients continuing the changed prescriptions showed no decrease in ADL or QOL after deprescribing, suggesting its rationality. The 10 measurement items of the Barthel Index were all suitable for evaluating the physical conditions of the patients. Meanwhile, SF-36v2 includes many items, but few indexes were directly applicable.
