The Time is Now for Mental Health Care: Evaluating the Impact of a Clinical Pharmacist on an Acute Mental Health Unit.

Background: Clinical pharmacists have a significant role in optimizing pharmacotherapy for patients admitted to acute care settings. Patients with mental health disorders are especially vulnerable to polypharmacy, adverse drug effects, medication nonadherence, and misconceptions about medication use. The Royal University Hospital in Saskatoon, Saskatchewan, currently lacks resources to provide optimal clinical pharmacy coverage for mental health inpatients.

Objectives: To determine the optimal clinical role for a pharmacist providing specialized care to mental health inpatients and to evaluate the potential impact of the pharmacist on medication use and patient care.

Methods: A pharmacist with 5 years of mental health-related pharmacy practice experience was temporarily assigned to the Mental Health Short Stay Unit as a practical component of a Master's program in pharmacy. Clinical activities to be completed by the pharmacist were defined on the basis of available evidence, existing performance and quality assurance indicators, and prior experience. The pharmacist's activities and recommendations during each shift were tracked and reported.

Results: The pharmacist saw 94 patients over a total of 88 hours. The pharmacist made a total of 61 recommendations, of which 55 (90%) were accepted by the psychiatrist, and initiated 42 medication changes. Forty-one patients (44%) received a thorough medication assessment, and individualized, often specialized, education was provided to patients 39 times. The pharmacist was consulted by the psychiatrist 19 times.

Conclusions: Pharmacists have an important role in medication management and patient education for psychiatric inpatients, and the health care team values pharmacists' unique expertise. Additional resources dedicated to defining and expanding clinical pharmacy services on inpatient psychiatry units could further optimize patient care.
