INTRODUCTION:The opioid drug epidemic is a major public health concern and an economic burden in the United States. The purpose of this systematic review is to assess the reliability and validity of screening instruments used in emergency medicine settings to detect opioid use in patients and to assess psychometric data for each screening instrument. METHODS:PubMed/MEDLINE, PsycINFO, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Web of Science, Cumulative Index to Nursing and Allied Health Literature and ClinicalTrials.gov were searched for articles published up to May 2018. The extracted articles were independently screened for eligibility by two reviewers. We extracted 1555 articles for initial screening and 95 articles were assessed for full-text eligibility. Six articles were extracted from the full-text assessment. RESULTS:Six instruments were identified from the final article list: Screener and Opioid Assessment for Patients with Pain - Revised; Drug Abuse Screening Test; Opioid Risk Tool; Current Opioid Misuse Measure; an Emergency Medicine Providers Clinician Assessment Questionnaire; and an Emergency Provider Impression Data Collection Form. Screening instrument characteristics, and reliability and validity data were extracted from the six studies. A meta-analysis was not conducted due to heterogeneity between the studies. CONCLUSIONS:There is a lack of validity and reliability evidence in all six articles; and sensitivity, specificity and predictive values varied between the different instruments. These instruments cannot be validated for use in emergency medicine settings. There is no clear evidence to state which screening instruments are appropriate for use in detecting opioid use disorders in emergency medicine patients. There is a need for brief, reliable, valid and feasible opioid use screening instruments in the emergency medicine setting.

Opioid-related Emergency Department (ED) visits have surged over the past decade. There is limited data on ED utilization patterns of patients with opioid use disorder (OUD). An improved understanding of utilization may underscore missed opportunities for screening, intervention and referral. This was a retrospective 2:1 matched case-control study conducted at a single urban ED. Cases were patients with an opioid-related index ED visit from June 1, 2017 to May 31, 2018. Controls were patients with a non-opioid related index ED visit from June 1, 2018 to May 31, 2019. The primary outcome was the association between the number of ED visits in the 24-month period surrounding the index visit (12 months prior and 12 months following) and having an opioid-related index ED visit. There were a total of 224 cases. One or more visits preceding (OR: 1.63, 95% CI: 1.17, 2.26) and following the index visit (OR: 2.69, 95% CI: 1.91, 3.78) was significantly associated with case status. Following adjustment, a higher number of visits preceding (aOR: 1.24, 95% CI: 1.08, 1.43) and following the index visit (aOR: 1.39, 95% CI: 1.23, 1.57) remained significantly associated with case status. Patients with an opioid-related index ED visit had significantly higher rates of ED utilization 12 months before and after the index visit when compared to a matched control population. These findings suggest that there are significant opportunities for ED intervention and referral to treatment both prior to and following an opioid-related ED visit in this patient population.

Introduction: In ED patients with acute drug overdose involving prescription medication and/or substances of abuse, severe QTc prolongation (> 500 ms) is predictive of adverse cardiovascular events (ACVE), defined as myocardial injury, ventricular dysrhythmia, shock, or cardiac arrest. However, it is unclear whether delayed severe QTc prolongation (dsQTp) is a risk factor for ACVE and if specific clinical factors are associated with occurrence of dsQTp. Methods: A secondary analysis of a prospective cohort of consecutive adult ED patients with acute drug overdose was performed on patients with initial QTc < 500 ms. The predictor variable, dsQTp, was defined as initial QTc < 500 ms followed by repeat QTc ≥ 500 ms. The primary outcome was occurrence of ACVE. Multivariable logistic regression was performed to test whether dsQTp was an independent predictor of ACVE and to derive clinical factors associated with dsQTp. Results: Of 2311 patients screened, 1648 patients were included. The dsQTp group (N = 27) was older than the control group (N = 1621) (51.6 vs 40.2, p < 0.001) and had a higher number of drug exposures (2.92 vs 2.16, p = 0.003). Following adjustment for age, sex, race/ethnicity, number of exposures, serum potassium, and opioid exposure, dsQTp remained an independent predictor of ACVE (aOR: 12.44, p < 0.0001). Clinical factors associated with dsQTp were age > 45 years and polydrug (≥ 3) overdoses. Conclusion: In this large secondary analysis of ED patients with acute drug overdose, dsQTp was an independent risk factor for in-hospital occurrence of ACVE. [ABSTRACT FROM AUTHOR]
