Abstract
BACKGROUND: Integration of clinical pharmacists into multidisciplinary Mental Health Hospital-in-the-Home teams is increasing but little is known about the medication safety contribution these pharmacists make. AIM: To evaluate whether clinical pharmacist involvement in a Mental Health Hospital-in-the-Home service improved medication safety key performance indicators. METHOD: Medical records were retrospectively reviewed of all patients admitted to 2 Western Australian Mental Health Hospital-in-the-Home services from September to November 2015. SITE 1: was a 16-bed service incorporating a clinical pharmacist as part of its multidisciplinary team. SITE 2: was a similarly structured 18-bed service but without clinical pharmacist involvement. The primary outcome measure was completion of medication safety key performance indicators obtained from the Western Australian Government Pharmaceutical Review Policy and mental health-specific best practice guidelines. RESULTS: Key performance indicators from Site 1 (n = 75 records), which incorporated a clinical pharmacist, demonstrated significantly (p < 0.001) higher rates of completion of medication reconciliation [65 (87%) versus 17 (29%)], accurate adverse drug reaction list [73 (97%) versus 34 (58%)], accurate discharge medication list [51 (74%) versus 18 (45%)], accurate medication profile [74 (99%) versus 40 (68%)] and medication chart review [74 (99%) versus 0 (0%)] than Site 2 (n = 59). CONCLUSION: Integrating a clinical pharmacist into a Mental Health Hospital-in-the-Home program significantly improved achievement of medication safety key performance indicators.
