Whale C, Henningsen J, Huff S, et al. - In this study, the impacts of Opioid Prescribing Guidelines (OPG) on the prescribing behavior of orthopedists following total knee arthroplasty (TKA) and total hip arthroplasty (THA) was tested. Researchers queried an institutional database to compare morphine equivalent dose (MED) prescribed at discharge, acute follow-up (<90 days), and chronic follow-up (>90 days) pre- and post-OPG. They distinguished cases over a 2-year period starting 1 year prior to OPG implementation. In this study, 1160 TKAs (692 pre-OPG, 468 post-OPG) and 834 THAs (530 pre-OPG, 304 post-OPG) were conducted by nine orthopaedic surgeons. The results of this study exhibit that orthopedists decreased total MED prescribed after TKA and THA following the onset of OPG. The majority of this reduce is explained by decreased MED at discharge. The data reveal that the post-OPG period saw slightly more new narcotics scripts written during acute follow-up.
