Abstract
BACKGROUND: Sedative use in older adults increases the risk of falls, fractures, and hospitalizations. The D-PRESCRIBE (Developing Pharmacist-Led Research to Educate and Sensitize Community Residents to the Inappropriate Prescriptions Burden in the Elderly), pragmatic randomized clinical trial demonstrated that community-based, pharmacist-led education delivered simultaneously to older adults and their primary care providers reduce the use of sedatives by 43% over 6 months. However, the associated health benefits and cost savings have yet to be described. This study evaluates the cost-effectiveness of the D-PRESCRIBE intervention compared to usual care for reducing the use of potentially inappropriate sedatives among older adults. METHODS: A cost-utility analysis from the public health care perspective of Canada estimated the costs and quality-adjusted life-years (QALYs) associated with the D-PRESCRIBE intervention compared to usual care over a 1-year time horizon. Transition probabilities, intervention effectiveness, utility, and costs were derived from the literature. Probabilistic analyses were performed using a decision tree and Markov model to estimate the incremental cost-effectiveness ratio. RESULTS: Compared to usual care, pharmacist-led deprescribing is less costly (-$1392.05 CAD) and more effective (0.0769 QALYs). Using common willingness-to-pay (WTP) thresholds of $50 000 and $100 000, D-PRESCRIBE was the optimal strategy. Scenario analysis indicated the cost-effectiveness of D-PRESCRIBE is sensitive to the rate of deprescribing. CONCLUSIONS: Community pharmacist-led deprescribing of sedatives is cost-effective, leading to greater quality-of-life and harm reduction among older adults. As the pharmacist's scope of practice expands, consideration should be given to interprofessional models of remuneration for quality prescribing and deprescribing services.
