PurposeQuantifying the impact of pharmacy interventions, such as tailored medicines optimisation, can be challenging owing to the sometimes-indirect nature of their effect on patient outcomes such A&E (Accident & Emergency) attendance, hospital admission and length of stay. This study aimed to assess the impact of the, Lewisham Integrated Medicines Optimisation Service (LIMOS) on medicines self-management, A&E attendances and hospital admissions.Patients And MethodsThe study was conducted as a retrospective and prospective observational evaluation of patients referred to LIMOS at University Hospital Lewisham between April and September 2016. Only patients with an appropriate referral that received a LIMOS intervention within the study period were considered eligible. The main outcomes examined pre- and post-LIMOS included medicines self-management, A&E attendance, number of admissions, as well as length of stay.ResultsData were collected for a total of 193 patients. Over half (56.4%, n = 109) identified as female with a mean age of 78 years at the time of referral. The number of hospital admissions decreased significantly post-LIMOS (-0.36 ± 1.87, 95% CI -0.63-0.10). Furthermore, the mean reduction in length of stay was significant and decreased by over a week (19.58 vs 11.09 days post-LIMOS, -7.67 ± 48.57, 95% CI -14.57--0.78). There was a significant increase in A&E visits observed post-intervention (0.78 ± 1.93, 95% CI 0.50-1.06); however, the majority (63%, n =165/261) occurred over 90 days post-intervention. There was a significant reduction in the number of patients self-managing medication post-LIMOS, with the number of patients receiving additional support with their medication increasing (-0.38 ± 0.50, 95% CI -0.45--0.31). LIMOS, therefore, successfully identified patients who were unable to manage their medicines.ConclusionSpecialist pharmacy interventions, which include support with medicines management, have a positive impact on admission avoidance and length of hospital stay.© 2022 Harrap et al.
