Abstract

Aim: To establish prevalence, sequelae and documentation of potentially inappropriate medication (PIM) use in older hospital in-patients. Methods: Notes of all patients ≥65 years old, admitted to our tertiary teaching hospital (January 2013), were retrospectively reviewed, and the Screening Tool of Older Persons' potentially inappropriate Prescriptions applied. Results: Amongst 534 patients, 54.8% (284) were on ≥1 PIM at admission, 26.8% on multiple; 60.8% were discharged on a PIM. Six percent of all admissions were potentially attributable to a PIM; falls associated with risk therapies were commonest (23/30), and often (65.2%) associated with serious injury. Pre-specified subgroup analysis (n = 100) identified 101 PIMs-at-discharge amongst 47 patients. In 82.2%, a clinical rationale for continued prescription was documented, with this communicated to the GP by letter in 71.1%. Conclusion: PIMs were common, and contributed to admission and injury. Hospitalisation provides an opportunity for medication rationalisation, and documentation of rationale for any PIM use.
