The PROMISING Project: A Pilot Study to Improve Geriatric Care Through a Pharmacist-Led Psychotropic Stewardship Program

Background and objective Psychotropic medications are frequently prescribed during acute care, even in older patients. They represent a risk for inappropriate long-term use and increase the overall risk of morbidity and mortality in this population. Our project aimed to evaluate the feasibility of a psychotropic medication stewardship program led by pharmacists. Methods We conducted a prospective, observational pilot study in patients aged 75 years and older, admitted to a surgical unit with at least one active prescription of a psychotropic medication (antipsychotic, benzodiazepine or non-benzodiazepine receptor agonist). Each psychotropic medication was assessed for potential deprescription, and if eligible, a recommendation from the stewardship pharmacist was made to the medical team. Results Among 183 patients, 93.4% were eligible for a potential deprescription. A total of 298 prescriptions were evaluated by the stewardship pharmacists, of which 57.7% were antipsychotics, 22.8% were benzodiazepines and 19.5% were non-benzodiazepine receptor agonists. Most of the assessed prescriptions were started during current hospitalization (62.7%). The median time required for the intervention per patient was 17 min 30 s. The stewardship pharmacists made 192 suggestions for 258 eligible prescriptions, with 69.8% being deprescription recommendations. Of all the deprescription suggestions, 75.4% were accepted by the medical team and 84.8% of those accepted persisted at discharge. Conclusion The implementation of a pharmacist-led psychotropic medication stewardship program on surgical units in our hospital is feasible and is a promising approach to improve geriatric care.
