Hip Knee

Background

This study evaluates the fate of unused opioids after total hip arthroplasty (THA) and total knee arthroplasty (TKA) at our facility.

Methods

Medication disposal after primary elective THA and TKA was classified as appropriate (in accordance with United States Food and Drug Administration guidelines) or inappropriate for all patients undergoing these procedures during the second half of the fiscal year 2015.

Results

In total, 199 THAs and 144 TKAs met inclusion criteria. Total pills prescribed were 55,635. Approximately 8925 (16%) of pills were unused. About 39.9% of patients disposed of unused opioids appropriately, while 60.1% of patients reported still having (18.5%), not knowing where they were (8.2%), or other (33.4%). There was no significant association with the type of opioid prescribed.

Conclusion

A large volume of unused opioids were improperly disposed of after total joint arthroplasty.
