OBJECTIVES
Older adults are often prescribed potentially inappropriate medications associated with adverse health outcomes and increased health services utilization. Developing Pharmacistâled Research to Educate and Sensitize Community Residents to the Inappropriate Prescriptions Burden in the Elderly (DâPRESCRIBE), a pragmatic randomized clinical trial, demonstrated how a community pharmacistâled evidenceâbased educational intervention successfully empowered communityâdwelling older adults and their physicians to reduce chronic use of inappropriate medications. The objective of this study was to evaluate the costâeffectiveness of the DâPRESCRIBE intervention for discontinuing nonsteroidal antiâinflammatory drugs (NSAIDs).
DESIGN
Costâeffectiveness analysis.
SETTING
Canada.
PARTICIPANTS
Communityâdwelling adults aged 65 years and older.
MEASUREMENTS
Decision analysis combining decision tree and Markov state transition modeling was developed to estimate the costâeffectiveness of DâPRESCRIBE (NSAIDs) compared with usual care from a Canadian healthcare system perspective with a time horizon of 1 year. Data from the DâPRESCRIBE trial and published literature were used to calculate effectiveness, utilities, and costs. Reference case and scenario analyses were conducted using probabilistic modeling. Sensitivity analyses assessed the robustness of the reference case model.
RESULTS
DâPRESCRIBE (NSAIDs) was less costly (â$1008.61) and more effective (.11 qualityâadjusted lifeâyears [QALYs]) than usual care and was the dominant strategy. At willingnessâtoâpay thresholds of $50â000 per QALY and $100â000 per QALY, DâPRESCRIBE (NSAIDs) incurred a positive incremental net benefit compared with usual care, suggesting it is costâeffective. Compared with the reference case, scenario analyses gave comparable QALYs with modest variation in cost estimates.
CONCLUSION
For communityâdwelling older adults, DâPRESCRIBE (NSAIDs) provides greater benefits at lower system costs, making it a compelling strategy to reduce the use and harms associated with chronic NSAID consumption. Our findings support reimbursing community pharmacistsâ clinical professional services for deprescribing inappropriate NSAIDs in communityâdwelling older adults. J Am Geriatr Soc 68:1090â1097, 2020
