Purpose To investigate the impact of medication reconciliation (MR), through avoidance of unintentional medication discrepancies, on enhanced recovery after surgery programs designed for older patients undergoing orthopedic joint surgery.  Method Our study was divided into two phases. In the first phase, MR was performed for elderly patients undergoing orthopedic joint surgery. Types of medication discrepancies and their potential risks were analyzed. In the second phase, a controlled study was conducted in a subgroup of patients diagnosed with periprosthetic joint infection (PJI) and who were scheduled for two-stage revision. The primary goal was to investigate the impact of MR on length of stay for the first stage. The secondary goal was to investigate the time between the first admission and the reimplantation of a new prosthesis, the number of readmissions within 30 days, hospitalization cost. Results A total of 506 medication discrepancies were identified in the included 260 patients. Intolerance had the highest incidence ( n  = 131, 25.7%). The Bayliff tool showed that 71.9% were assessed as level 2 risk, and 10.3% had a life-threatening risk. For patients with PJI, MR reduced the average length of stay in the first stage (16.3 days vs. 20.7 days, P  = 0.03) and shortened the time (57.3 days vs. 70.5 days, P  = 0.002) between the first admission and the reimplantation of a new prosthesis. The average cost of hospital stay ($8589.6 vs. $10,422.6, P  = 0.021), antibiotics ($1052.2 vs. $1484.7, P  = 0.032) and other medications ($691.5 vs. $1237.6, P  = 0.014) per patient at our hospital were significantly decreased. Notably, significant improvements in patient satisfaction were seen in participants in the MR group. Conclusion Through MR by clinical pharmacists, medication discrepancies within the orthopedic ERAS program could be identified. For patients with periprosthetic joint infection, better patient satisfaction and clinical and economical outcomes can be achieved with this method.
