Randomized Controlled Trial Multicenter StudyCombination of Perineural and Wound Infusion After Above Knee Amputation - A randomized, controlled multicenter study.
Post-operative pain after an above-knee amputation is often severe, and in the elderly patients the adverse effects of post-operative opioids are evident. We hypothesized that continuous perineural local anesthetic infusion (CPI) combined to a wound infusion will reduce acute pain and opioid consumption compared to placebo after above knee amputation. ⋯ A combination of continuous perineural and wound local anesthetic infusion seems to diminish the intensity of stump pain after above knee amputation.

Multicenter StudyNational Variation in Opioid Prescription Fills and Long-Term Use in Opioid Naïve Patients after Urological Surgery.
Prescription opioid use is increasing, leading to increased addiction and mortality. Postoperative care is often the first exposure to opioids of a patient but little data exist on national prescription patterns in urology. We examined post-discharge opioid fills after urological procedures and the association with long-term use. ⋯ National variation in opioid prescribing practice exists after urological operations. Patients who fill larger amounts of opioids after certain major and minor urological procedures are at increased risk for long-term opioid use. This provides evidence for procedure specific prescribing guidelines to minimize risk and promote standardization.

Multicenter Study
Development of machine learning algorithms for prediction of prolonged opioid prescription after surgery for lumbar disc herniation.
Spine surgery has been identified as a risk factor for prolonged postoperative opioid use. Preoperative prediction of opioid use could improve risk stratification, shared decision-making, and patient counseling before surgery. ⋯ Overall, 5,413 patients were identified, with sustained postoperative opioid prescription of 416 (7.7%) at 90 to 180 days after surgery. The elastic-net penalized logistic regression model had the best discrimination (c-statistic 0.81) and good calibration and overall performance; the three most important predictors were: instrumentation, duration of preoperative opioid prescription, and comorbidity of depression. The final models were incorporated into an open access web application able to provide predictions as well as patient-specific explanations of the results generated by the algorithms. The application can be found here: https://sorg-apps.shinyapps.io/lumbardiscopioid/ CONCLUSION: Preoperative prediction of prolonged postoperative opioid prescription can help identify candidates for increased surveillance after surgery. Patient-centered explanations of predictions can enhance both shared decision-making and quality of care.

Randomized Controlled Trial Multicenter StudyEfficacy and Safety of an Intravenous Acetaminophen/Ibuprofen Fixed-dose Combination After Bunionectomy: a Randomized, Double-blind, Factorial, Placebo-controlled Trial.
Multimodal analgesia with acetaminophen and/or nonsteroidal anti-inflammatory drugs is recommended for the treatment of postoperative pain. Although oral fixed-dose combinations (FDCs) are available, parenteral administration may be clinically justified. The goal of this study was to investigate the clinical efficacy and safety of an intravenous FDC of ibuprofen and acetaminophen after bunionectomy. ⋯ The study found that repeated administration of an intravenous FDC of ibuprofen and acetaminophen provided statistically significant improvement in SPID48 over comparable doses of either monotherapy without an increase in adverse events. ClinicalTrials.gov identifier: NCT02689063.

Randomized Controlled Trial Multicenter Study
Onset of action of naldemedine in the treatment of opioid-induced constipation in patients with chronic noncancer pain: results from 2 randomized, placebocontrolled, phase 3 trials.
Opioid-induced constipation (OIC) is a common side effect of chronic opioid therapy. Previously, naldemedine, a peripherally acting μ-opioid receptor antagonist demonstrated efficacy in the treatment of OIC. In this exploratory analysis, the onset of action of naldemedine was evaluated in 2 identically designed phase 3, randomized, placebo-controlled trials. ⋯ Treatment-emergent adverse events were reported most frequently on day 1, followed by a decrease from days 2 to 7. Naldemedine had a timely onset of effect, and gastrointestinal adverse events largely resolved within the first week. These findings should assist clinicians counseling patients with chronic noncancer pain on expectations when initiating naldemedine for OIC.
