Institutional Guidelines Can Decrease the Amount of Opioids Prescribed After Total Joint Replacement.

Background: In the midst of the nationwide opioid epidemic, our institution began an effort to improve the education of opioid prescribers and disseminate procedure-specific guidelines for the number of opioid pills to prescribe post-operatively for total joint arthroplasty. The number of opioid pills suggested for total hip or knee replacement was 70 tablets.

Questions/Purposes: We sought to evaluate the impact of the new institutional guideline on opioid prescribing practices, hypothesizing that it would lead to a decrease in the number of pills prescribed but an increase in patient call volume after discharge.

Methods: After the new guidelines were implemented in February 2018, we retrospectively reviewed all opioid prescriptions written for patients on the joint-replacement service from March 2016 to March 2018. In addition, we tabulated post-operative telephone calls made to the nurse practitioner service before and after guideline implementation. The majority of calls to the nurse practitioner service are for opioid renewals.

Results: We included 9514 patients in the analysis. Prior to guideline implementation, the mean number of pills prescribed after primary total joint arthroplasty was 91 ± 26.6 pills and after it was 65 ± 16.3 pills. The monthly number of unique patient telephone interactions was statistically significantly lower after the implementation of the new guidelines.

Conclusion: An institutional guideline for opioid prescribing after total joint arthroplasty significantly reduced the number of pills prescribed to patients without causing a significant increase in the number of phone calls to the service.
