Impact of an Interprofessional Collaboration Between Physicians and Pharmacists on Fall-Risk-Increasing Drugs in Older Patients with Trauma in the Emergency Department

<b>Background/Objectives</b>: In older patients, falls constitute a significant public health concern and a major cause of hospital admission. Fall-risk-increasing drugs (FRIDs) represent a key risk factor for falls. Therefore, modifying these drugs represents an important strategy for preventing recurrent falls and further patient harm. The objective of this study was to evaluate a structured interprofessional collaboration between physicians and pharmacists on managing FRIDs in older patients who present to the emergency department (ED) after a fall. <b>Methods</b>: This study was performed in the ED of a tertiary care hospital. Patients who were >65 years old and presented to the ED after a fall were included. A routine care group was included between 1 March 2020 and 31 May 2020. A pharmaceutical care group was included between 1 September 2023 and 30 November 2023. In the pharmaceutical care group, a clinical pharmacist supported the physicians in identifying and managing FRIDs. Possible solutions for improving FRID prescription were discussed interprofessionally. The number of FRIDs at ED admission and discharge, as well as the number of FRID modifications, were evaluated. <b>Results</b>: A total of 107 patients were enrolled in each group. There were 85 patients in the routine care group and 89 patients in the pharmaceutical care group, with at least 1 FRID prescribed at ED admission (<i>p</i> = 0.483). At ED discharge, there were 85 patients in the routine care group and 68 patients in the pharmaceutical care group, with at least 1 FRID prescribed at (<i>p</i> = 0.010). There were seven FRID modifications in the routine care group compared to 125 FRID modifications in the pharmaceutical care group. <b>Conclusions</b>: In this study, the interprofessional collaboration between physicians and pharmacists led to a reduced number of FRIDs being prescribed and more FRID modifications in older patients at ED discharge. Further research is required to ascertain the feasibility of integrating this single intervention into a multifactorial fall prevention program.
