Abstract
AbstractBackgroundGlobal increases in opioid prescribing and misuse have prompted calls for closer regulation. Opioid prescription following surgery may lead to long term opioid use. A study was conducted evaluating opioid prescriptions on hospital discharge following common general surgery operations in the Bay of Plenty.MethodsRetrospective observational study over a two‐year period in two regional New Zealand hospitals. Six hundred and eleven patients aged 18–64 years were assessed. Patients with complications, readmission, and a prescription of opioids in the preceding 3 months were excluded.ResultsA total of 460 patients (165 Laparoscopic Cholecystectomy (LC), 200 Laparoscopic Appendicectomy (LA) and 95 Open Inguinal Hernia Repair (OIHR)) were included in analysis. Opioids were prescribed to 53% of LC, 55% of LA, and 60% of OIHR patients, with a mean of 75.8 Morphine Milligram Equivalents (MMEs), 75.3 MMEs, and 82.8 MMEs respectively. Seven percent of patients (18/254) received a second opioid prescription within 3 months, and of those only 1.6% (4/254) received a further prescription between 3 and 6 months from discharge. Opioid prescribing did not correlate with operation, ethnicity, age, length of stay, or gender, except for males receiving a more MMEs than females following LC (mean 102.0 MMEs versus 65.4 MMEs, P = 0.017).ConclusionThis study shows a rate of opioid prescribing lower than the USA, and greater than seen in an Australian setting. Substantial amounts of opioids were prescribed following uncomplicated surgery, with significant variability. Improvements in training in post‐operative opioid prescribing are needed. Fortunately, rates of ongoing opioid use were low.
