Abstract
Background
Patterns of opioid overprescribing following arthroplasty likely developed given that poor pain control can diminish patient satisfaction, delay disposition, and lead to complications. Recently, interventions promoting responsible pain management have been described however most of the existing literature focuses on opioid naive patients. We sought to describe the effect of an educational intervention on prescribing for opioid tolerant patients.
Methods
As the start to a quality improvement initiative to reduce opioid overprescribing, a departmental grand rounds was conducted. Prescribing data, for the year before and after this intervention, were retrospectively collected for all opioid tolerant patients undergoing primary total knee arthroplasty (TKA) and primary total hip arthroplasty (THA). Opioid prescribing data was standardized to mean morphine equivalents (MME). Segmented time series regression was utilized to estimate the change in opioid prescribing associated with the intervention.
Results
A total of 508 opioid tolerant patients underwent TKA and 342 opioid tolerant patients underwent THA at our institution during the study period. The intervention was associated with a statistically significant decrease of 468 mean MME (23%) from 2,062 to 1,594 (P=0.005)in TKA patients and 594 mean MME (28%) from 2,159 to 1,565 (P=0.003) in THA patients. There were no readmissions for pain control during the study period.
Conclusions
This study demonstrates an educational intervention is associated with decreased opioid prescribing to opioid tolerant arthroplasty patients. While the effective management of these patients is challenging, surgeon education should be a key focus to optimizing their care.
Level of Evidence
