RESUMO
BACKGROUND: The USA provides medical services to its military veterans through Veterans Health Administration (VHA) medical centers. Passage of recent legislation has increased the number of veterans having VHA-paid orthopedic surgery at non-VHA facilities. METHODS: We conducted a retrospective cohort study among veterans who underwent orthopedic joint surgery paid for by the VHA either at the Salt Lake City VHA Medical Center (VAMC) or at non-VHA hospitals between January 2018 and December 2021. 562 patients were included in the study, of which 323 used a non-VHA hospital and 239 patients the VAMC. The number of opioid tablets prescribed at discharge, the total number prescribed by postdischarge day 90, and the number of patients still filling opioid prescriptions between 90 and 120 days after surgery were compared between groups. RESULTS: Veterans who underwent orthopedic surgery at a non-VHA hospital were prescribed more opioid tablets at discharge (median (IQR)); (40 (30-60) non-VHA vs 30 (20-47.5) VAMC, p<0.001) and in the first 90 days after surgery than patients who had surgery at the Salt Lake City VAMC (60 (40-120) vs 35 (20-60), p<0.001). Patients who had surgery at Salt Lake City VAMC were also significantly less likely to fill opioid prescriptions past 90 days after hospital discharge (OR (95% CI) 0.06 (0.01 to 0.48), p=0.007). CONCLUSION: These results suggest that veterans who have surgery at a veterans affairs hospital with a transitional pain service are at lower risk for larger opioid prescriptions both at discharge and within 90 days after surgery as well as persistent opioid use beyond 90 days after discharge than if they have surgery at a community hospital.
RESUMO
INTRODUCTION: Understanding postoperative opioid use patterns among different populations is key to developing opioid stewardship programs. METHODS: We performed a retrospective cohort study on opioid prescribing, use, and pain after general surgery procedures for patients cared for by a transitional pain service at a veterans administration hospital. Discharge opioid prescription quantity, 90-day opioid prescription, and patient reported outcome pain measures were compared between chronic opioid users and non-opioid users (NOU). Additionally, 90-day total opioid use was evaluated for NOU. RESULTS: Of 257 patients, 34 (13%) were on chronic opioid therapy, over 50% had a mental health disorder, and 29% had a history and/or presence of a substance use disorder. NOU were prescribed a median (IQR) of 10 (7, 12) tablets at discharge, while chronic opioid users were prescribed 6 (0, 12) tablets (p<0.001). 90-day opioid prescription (not including baseline opioid prescription for chronic users) was 10 (7, 15) and 6 (0, 12) tablets, respectively (p=0.001). There were no differences in changes in pain intensity or pain interference scores during recovery between groups. Median 90-day opioid use post discharge for NOU was 4 (0, 10) pills. DISCUSSION: Non-opioid and chronic opioid users required very few opioid pills following surgery, and patients on chronic opioid therapy quickly returned to their baseline opioid use after a small opioid prescription at discharge. There was no difference in pain recovery between groups. Opioid prescribing guidelines should include patients on chronic opioid therapy and could consider recommending a more conservative prescribing approach.
