A Reduction in Opioid Prescription Size After Total Joint Arthroplasty Can be Safely Performed Without an Increase in Complications.

BACKGROUND: Excessive opioid prescriptions after total joint arthroplasty (TJA) increase risks for adverse opioid-related events, chronic opioid use, and unlawful opioid diversion. Decreasing postoperative prescriptions may improve quality after TJA. Concerns exist that a decrease in opioids prescribed may increase complications, such as readmissions, emergency department (ED) visits, or worsened patient-reported outcomes (PROs). The purpose of this study was to explore whether a reduction in opioids prescribed after TJA resulted in increased complications. METHODS: Data originated from a statewide database prospectively abstracted, including oral morphine equivalents prescribed at discharge, readmissions, ED visits, and PROs. Data were collected from 84,998 TJA occurring 1 year before and after the creation of an opioid-prescribing protocol that had decreased prescriptions by approximately 50%. Trends were monitored using Shewhart control charts. Regression models were used to determine statistically significant changes over time. RESULTS: All groups showed a reduction in opioids prescribed by almost 50% without an increase in emergency room visits or readmissions and without a detrimental effect on PROs. Compared to baseline data before opioid reduction, opioid-naive total knee arthroplasty had significant improvements in all outcomes (P = .03, P = .02, P < .001, P < .001). Opioid-tolerant total knee arthroplasty and total hip arthroplasty had no worsened outcomes and significant improvement in (Knee Injury and Osteoarthritis Outcome score for Joint Replacement P = .03) and (Hip Disability and Osteoarthritis Outcome Score for Joint Replacement P = .03). Opioid-naive total hip arthroplasty had significant improvements in Hip Disability and Osteoarthritis Outcome Score Joint Replacement (P = .003) and Patient Reported Outcomes Measurement Information System (P = .001). CONCLUSIONS: Postoperative opioid prescription recommendations from a statewide registry decreased prescribing by approximately 50% without decreasing PROs or increasing ED visits or readmissions. A reduction in opioids prescribed after TJA can be accomplished safely and without increased complications.

John N. Insall Award: MARCQI's Pain-Control Optimization Pathway (POP): Impact of Registry Data and Education on Opioid Utilization.

BACKGROUND: In 2019, the Michigan Arthroplasty Registry Collaborative Quality Initiative (MARCQI) recommended an evidence-based opioid pain pathway to participating physicians and hospitals for patients undergoing total joint arthroplasty (TJA). The purpose of this study was to determine if the education could influence and have lasting effects on the prescribing patterns for TJA patients. METHODS: Using the MARCQI database, the number of oral morphine equivalents (OMEs) prescribed at discharge were collected from January 2018 through December 2019 for all primary arthroplasty procedures. Periods compared included before and after July 2018 Michigan opioid laws as well as before and after the March 2019 MARCQI recommendations. The data compared total hip arthroplasty (THA) and total knee arthroplasty (TKA) patients, opioid-naive vs opioid-tolerant patients, individual surgeons, and MARCQI sites. RESULTS: The data included 84,998 TJAs: 22,774 opioid-naive THAs, 9124 opioid-tolerant THAs, 40,882 opioid-naive TKAs, and 12,218 opioid-tolerant TKAs. In all the groups and at all time periods there were a significant decrease in prescriptions (P < .001). Individual surgeons and participating sites also demonstrated decreased OMEs on discharge after the recommendations. Between the first and last months of collection, this represented an overall decrease of opioid OMEs for THA by 47.1% for opioid-naive patients and 53.4% for opioid-tolerant patients. For TKA patients, the OME decrease was 48.3% for opioid-naive patients, and 48.4% for opioid-tolerant patients. CONCLUSION: The MARCQI pain control optimization pathway (POP) program has been successful in drastically reducing opioid prescribing with lasting effects, which has substantially limited the overall opioid prescription burden for patients undergoing arthroplasty.
