Pharmacist Review of Medicines Following Ambulance-Attended Falls—A Multi-Methods Evaluation of a Quality Improvement Initiative

Background: Falls in older adults are a leading cause of morbidity, particularly when compounded by polypharmacy. There is mixed evidence of the efficacy of medicine reviews, but there is little work exploring this in the ambulance setting. A new referral pathway enabling ambulance staff to connect patients to primary care pharmacists aimed to address this. This study explored staff and patient experiences with the pathway and its potential to improve medication safety after a fall. Methods: A mixed-method service evaluation was conducted to assess the implementation and impact of this pathway. Routine data from an ambulance trust and pharmacist proformas were used to address objectives relating to referral rates, clinical appropriateness, and fall recurrence. Patient and staff stakeholder perspectives were gathered through two cross-sectional surveys designed to explore emotional, behavioral, and practical responses to the intervention. Quantitative data were analyzed descriptively and using ordinal logistic regression where appropriate. Free-text responses were analyzed thematically. Results: Between May 2019 and March 2020, referrals were initiated for 775 older adults after ambulance attendance for a fall, with pharmacists completing medicine reviews on 340 patients. Survey data revealed improvements in patients’ emotional responses to their medicines. Ambulance clinicians identified patient disclosure, stockpiling, and the presence of expired medicines as key indicators of poor medicines management and valued the ability to refer patients. Conclusions: Overall, referral to the pathway demonstrates a marginal improvement in recontact rates in the short-term but does not necessarily represent an improvement in overall patient safety. The cost of such an intervention and patient expectations need further exploration to prove efficacy and patient satisfaction.
