ABSTRACT

Background: Overdose deaths from fentanyl and its analogs have increased significantly since 2013. There are limited data regarding the prevalence of fentanyl exposure among emergency department (ED) patients with active opioid use.Methods: We conducted a cross-sectional study at an urban hospital from May 20 to July 30, 2018. A convenience sample of adult ED patients with active opioid use, defined as opioid use within seven days prior to ED visit, were enrolled. Rapid Response® Single Drug Test Strip (BTNX Inc., Markham, Canada) was used to detect fentanyl in urine samples. Information on demographic, substance use history, and knowledge of fentanyl was obtained using a brief survey tool. Our primary outcome was the prevalence of fentanyl exposure; secondary outcomes included patients' knowledge regarding potency, risk of overdose death from fentanyl and intentional purchase of fentanyl.Results: During our study period, 451 patients reported active substance use. Of these, 208 reported active opioid use and 165 consented for the study. The median age was 49 years [interquartile range: 38, 57] and 77.0% (n = 127) were male; 42 participants (25.5%) presented to ED after an acute overdose event. Heroin was the preferred opioid of use in 90.8% of the participants, primarily via intranasal route (64.6%). Polysubstance use was reported in 98.8%, most commonly with cocaine (57.6%; n = 95). Fentanyl was detected in 104 out of 129 urine samples tested (80.6%). 84.2% (n = 139) identified fentanyl as highly potent and 85.5% (n = 141) recognized highest risk of death in fentanyl overdose. A larger proportion of non-overdose participants intentionally purchased fentanyl (34.1%; n = 42) compared to the overdose group (16.7%, n = 7; p = .04).Conclusions: The majority of ED patient with active opiate use were exposed to fentanyl while one in three participants intentionally purchased fentanyl despite their awareness of its potency and the high-risk of death from overdose.

ABSTRACT

BACKGROUND: In an emergency department (ED), intravenous (IV) access is frequently accomplished by inspection and palpation of peripheral veins. Failure of these methods indicates severe IV access difficulty and necessitates advanced techniques. Here, we estimate the incidence of advanced IV access in 2 urban EDs with varying resident coverage. METHODS: In this multiple-cohort study, we enrolled data from 2 neighboring urban EDs-a tertiary care ED and a community hospital affiliate. The 2 have similar volumes but the tertiary care ED has more resident coverage (112 vs 20 hours/d). In a prospective data collection (April 2012-2013), we enrolled consecutive patients during hours of scheduled shifts for research assistants. In a retrospective data collection (March 2011-2012), we reviewed charts of a random sample of patients from each ED for similar outcomes. We calculated the incidence of advanced IV access by dividing the number requiring advanced techniques by the number requiring IV access. RESULTS: We determined IV outcomes for 790 patients in the prospective cohort and 669 patients in the retrospective cohort. Between groups, there was no difference in the incidence of advanced IV access in the prospective collection (P = .08) or in the retrospective collection (P = .7). Pooling data from both cohorts and both hospitals, the overall incidence was 3.2 [95% confidence interval, 1.9-5.2] per 100 attempts. CONCLUSION: Advanced IV access is needed in 3.2% of IV attempts in 2 urban EDs with varying levels of resident coverage. We found similar incidence in both EDs.
