Objective Elective surgery suffered significant loss of capacity during the COVID-19 pandemic. To address this, hip and knee arthroplasties are being conducted as day case procedures. Pre-admission pharmacist consultations were introduced (the intervention) for these patients. This consultation aimed to address perioperative medicines issues, promote patient empowerment, improve prescribing quality and contribute to reduction in length of stay (LoS). Methods All patients listed for a total/ unicompartmental knee replacement (TKR/UKR) or total hip replacement (THR) at an ambulatory care hospital were identified by a pharmacist prescriber 1-2 weeks before the operation. Pharmacist consultations were conducted remotely with discharge prescriptions written electronically and dispensed before admission. Prescribing data were collected for both pre-intervention (n=80) and post-intervention (n=129) groups along with all interventions undertaken during consultations. Staff opinion was sought via online questionnaire and patient opinion was gathered via post-discharge telephone calls. Results A total of 115 interventions took place during 129 patient consultations and >75% of interventions were of a significance expected to improve patient care. Prescribing standards were improved in the intervention group compared with patients whose arthroplasty was before the introduction of this service. The pharmacy service would have produced a different prescription in 38.8% of the pre-intervention group. Staff and patient feedback was extremely positive and all patients with previous surgical experience in the health board reported an improved experience. There was a statistically significant reduction in post-discharge healthcare encounters (such as general practitioner (GP) visits) in the intervention group. Conclusion This novel remote preoperative pharmacist consultation improved prescribing standards, enhanced the patient's surgical experience and reduced the burden on post-discharge healthcare systems.
