Background The current mainstay of orthopaedic pain control is opioid analgesics but there are few studies in the literature evaluating the effects of opioids on bone healing. Questions/purposes The purpose of this study was to use a rat fracture model to evaluate the effects of opioid administration on osseous union in the acute (4 weeks) and subacute (8 weeks) setting in an operatively stabilized fracture. We asked the following question: does morphine administration alter (1) fracture callus strength; (2) callus volume and formation; and (3) morphology and early remodeling to final osseous union? Methods A 0.4-mm femoral osteotomy gap was created in 50 Sprague-Dawley rats using an established model. Postoperatively, rats were randomized to control versus morphine-treated study groups. Equal numbers of rats from each group were euthanized at 4 weeks and 8 weeks postoperatively. Three-point bend biomechanical testing was performed to evaluate postoperative callus strength. Micro-CT scans and histological analyses were used to evaluate postoperative callus volume and formation, morphology, and features of early remodeling. Results Biomechanical testing identified a statistically significant (p = 0.048) reduction in callus strength in morphine-treated animals 8 weeks postoperatively compared with controls. Radiographic and histological analysis showed delayed callus maturation and lack of remodeling in the morphine group compared with control animals at 8 weeks. Micro-CT analysis expressed remodeling and resorption as a decrease in callus volume over the two time points. The control group had significant levels of resorption decreasing 29% (p = 0.023) over the 4-week to 8-week time interval. Morphine administration inhibited callus resorption and remodeling with only a 13% decrease (p = 0.393) in callus volume comparing these time points. The callus inhibition associated with morphine administration was not as evident in the acute, 4-week time setting. Conclusions Morphine administration inhibited callus strength in this animal model. This finding is likely consistent with the observation that the callus and healing bone appear to have a decreased rate of maturation and remodeling seen at 8 weeks.Clinical Relevance This study identifies that administration of an opioid pain medication leads to weaker callus and impedes callus maturation compared with controls.
Objectives Quality and safety review for performance improvement is important for systems of care and is required for US academic emergency departments (EDs). Assessment of the impact of patient safety initiatives in the context of increasing burdens of quality measurement compels standardized, meaningful, high-yield approaches for performance review. Limited data describe how quality and safety reviews are currently conducted and how well they perform in detecting patient harm and areas for improvement. We hypothesized that decades-old approaches used in many academic EDs are inefficient and low yield for identifying patient harm. Methods We conducted a prospective observational study to evaluate the efficiency and yield of current quality review processes at five academic EDs for a 12-month period. Sites provided descriptions of their current practice and collected summary data on the number and severity of events identified in their reviews and the referral sources that led to their capture. Categories of common referral sources were established at the beginning of the study. Sites used the Institute for Healthcare Improvement's definition in defining an adverse event and a modified National Coordinating Council for Medication Error Reporting and Prevention (MERP) Index for grading severity of events. Results Participating sites had similar processes for quality review, including a two-level review process, monthly reviews and conferences, similar screening criteria, and a grading system for evaluating cases. In 60 months of data collection, we reviewed a total of 4735 cases and identified 381 events. This included 287 near-misses, errors/events (MERP A–I) and 94 adverse events (AEs) (MERP E–I). The overall AE rate (event rate with harm) was 1.99 (95% confidence interval = 1.62%–2.43%), ranging from 1.24% to 3.47% across sites. The overall rate of quality concerns (events without harm) was 6.06% (5.42%–6.78%), ranging from 2.96% to 10.95% across sites. Seventy-two–hour returns were the most frequent referral source used, accounting for 47% of the cases reviewed but with a yield of only 0.81% in identifying harm. Other referral sources similarly had very low yields. External referrals were the highest yield referral source, with 14.34% (10.64%–19.03%) identifying AEs. As a percentage of the 94 AEs identified, external referrals also accounted for 41.49% of cases. Conclusions With an overall adverse event rate of 1.99%, commonly used referral sources seem to be low yield and inefficient for detecting patient harm. Approximately 6% of the cases identified by these criteria yielded a near miss or quality concern. New approaches to quality and safety review in the ED are needed to optimize their yield and efficiency for identifying harm and areas for improvement.
Dexmedetomidine has previously been used only for short-term, procedural sedation in children. The purpose of this review was to describe the dosing, safety, and efficacy of dexmedetomidine for sustained sedation in intubated pediatric burn patients. The authors reviewed acutely burned children treated between 2005 and 2008 who were intubated during their course of care and who received dexmedetomidine for sedation. Patients served as their own controls using the time periods when they received sedatives other than dexmedetomidine. Eleven patients with 17 dexmedetomidine treatment courses were identified. The median patient age was 7 years (range 1.6-17 years), and median burn size was 30.5% TBSA (range 6-59%). Patients were ventilated for a median of 9 days (range 4-46 days). The median initial dose of dexmedetomidine was 0.39 μg/kg/hr (range 0.10-1.16 μg/kg/hr), with a median infusion dose of 0.57 μg/kg/hr (range 0.11-1.17 μg/kg/hr) and median treatment duration of 40 hours (range 1-356 hours). None of the patients received dexmedetomidine loading dose. Patients achieved more appropriate Riker scores while treated with dexmedetomidine than while being treated with other sedatives (3.8 vs 3.3, P = .003). The incidence of hypotension and/or bradycardia while on dexmedetomidine was not greater than when it was not being used. Clinically significant rebound hypertension and tachycardia were absent on discontinuation of dexmedetomidine. No unplanned extubations were observed. Median length of hospital stay was 49 days (range 7-118 days). Dexmedetomidine seems to be safe and effective for sedation of pediatric burn patients on mechanical ventilation with close cardiovascular monitoring.

Equity in the promotion of women and underrepresented minorities (URiM) is essential for the advancement of academic emergency medicine and the specialty as a whole. Forward-thinking healthcare organizations can best position themselves to optimally care for an increasingly diverse patient population and mentor trainees by championing increased diversity in senior faculty ranks, leadership, and governance roles. This article explores several potential solutions to addressing inequities that hinder the advancement of women and URiM faculty. It is intended to complement the recently approved American College of Emergency Physicians (ACEP) policy statement
