Detecting aberrant opioid behavior in the emergency department: a prospective study using the screener and Opioid Assessment for Patients with Pain-Revised (SOAPP®-R), Current Opioid Misuse Measure (COMM)™, and provider gestalt

Emergency department (ED) providers have limited time to evaluate patients at risk for opioid misuse. A validated tool to assess the risk for aberrant opioid behavior may mitigate adverse sequelae associated with prescription opioid misuse. We sought to determine if SOAPP-R, COMM, and provider gestalt were able to identify patients at risk for prescription opioid misuse as determined by pharmacy records at 12xa0months. We conducted a prospective observational study of adult patients in a high volume US ED. Patients completed the SOAPP-R and COMM, and treating EM providers evaluated patients’ opioid misuse risk. We performed variable-centered, person-centered, and hierarchical cluster analyses to determine whether provider gestalt, SOAPP-R, or COMM, or a combination, predicted higher misuse risk. The primary outcome was the number of opioid prescriptions at 12xa0months according to pharmacy records. For 169 patients (mean age 43xa0years, 51% female, 73% white), correlation analysis showed a strong relationship between SOAPP-R and COMM with predicting the number of opioid prescriptions dispensed at 12xa0months. Provider scores estimating opioid misuse were not related to SOAPP-R and only weakly associated with COMM. In our adjusted regression models, provider gestalt and SOAPP-R uniquely predicted opioid prescriptions at 6 and 12xa0months. Using designated cutoff scores, only SOAPP-R detected a difference in the number of opioid prescriptions. Cluster analysis revealed that provider gestalt, SOAPP-R, and COMM scores jointly predicted opioid prescriptions. Provider gestalt and self-report instruments uniquely predicted the number of opioid prescriptions in ED patients. A combination of gestalt and self-assessment scores can be used to identify at-risk patients who otherwise miss the cutoff scores for SOAPP-R and COMM.

Emergency Department Intubation Success With Succinylcholine Versus Rocuronium: A National Emergency Airway Registry Study

Study objective: Although both succinylcholine and rocuronium are used to facilitate emergency department (ED) rapid sequence intubation, the difference in intubation success rate between them is unknown. We compare first‐pass intubation success between ED rapid sequence intubation facilitated by succinylcholine versus rocuronium. Methods: We analyzed prospectively collected data from the National Emergency Airway Registry, a multicenter registry collecting data on all intubations performed in 22 EDs. We included intubations of patients older than 14 years who received succinylcholine or rocuronium during 2016. We compared the first‐pass intubation success between patients receiving succinylcholine and those receiving rocuronium. We also compared the incidence of adverse events (cardiac arrest, dental trauma, direct airway injury, dysrhythmias, epistaxis, esophageal intubation, hypotension, hypoxia, iatrogenic bleeding, laryngoscope failure, laryngospasm, lip laceration, main‐stem bronchus intubation, malignant hyperthermia, medication error, pharyngeal laceration, pneumothorax, endotracheal tube cuff failure, and vomiting). We conducted subgroup analyses stratified by paralytic weight‐based dose. Results: There were 2,275 rapid sequence intubations facilitated by succinylcholine and 1,800 by rocuronium. Patients receiving succinylcholine were younger and more likely to undergo intubation with video laryngoscopy and by more experienced providers. First‐pass intubation success rate was 87.0% with succinylcholine versus 87.5% with rocuronium (adjusted odds ratio 0.9; 95% confidence interval 0.6 to 1.3). The incidence of any adverse event was also comparable between these agents: 14.7% for succinylcholine versus 14.8% for rocuronium (adjusted odds ratio 1.1; 95% confidence interval 0.9 to 1.3). We observed similar results when they were stratified by paralytic weight‐based dose. Conclusion: In this large observational series, we did not detect an association between paralytic choice and first‐pass rapid sequence intubation success or peri‐intubation adverse events.

Association of prehospital intubation with decreased survival among pediatric trauma patients in Iraq and Afghanistan

Introduction: Airway compromise is the second leading cause of preventable death on the battlefield among US military casualties. Airway management is an important component of pediatric trauma care. Yet, intubation is a challenging skill with which many prehospital providers have limited pediatric experience. We compare mortality among pediatric trauma patients undergoing intubation in the prehospital setting versus a fixed‐facility emergency department. Methods: We queried the Department of Defense Trauma Registry (DODTR) for all pediatric encounters in Iraq and Afghanistan from January 2007 to January 2016. We compared outcomes of pediatric subjects undergoing intubation in the prehospital setting versus the emergency department (ED) setting. Results: During this period, there were 3439 pediatric encounters (8.0% of DODTR encounters during this time). Of those, 802 (23.3%) underwent intubation (prehospital = 211, ED = 591). Compared to patients undergoing ED intubation, patients undergoing prehospital intubation had higher median composite injury severity scores (17 versus 16) and lower survival rates (66.8% versus 79.9%, p < 0.001). On univariable logistic regression analysis, prehospital intubation increased mortality odds (OR 1.97, 95% CI 1.39–2.79). After adjusting for confounders, the association between prehospital intubation and death remained significant (OR 2.03, 95% CI 1.35–3.06). Conclusions: Pediatric trauma subjects intubated in the prehospital setting had worse outcomes than those intubated in the ED. This finding persisted after controlling for measurable confounders.

Prehospital Application of Hemostatic Agents in Iraq and Afghanistan

Abstract Introduction: Hemorrhage is the leading cause of death on the battlefield. Development of chitosan- and kaolin-based hemostatic agents has improved hemorrhage control options. Sparse data exists on the use of these agents in the prehospital, combat setting. We describe recent use of these agents and compare patients receiving hemostatic to the baseline population. Methods: We used a series of emergency department (ED) procedure codes to identify patients within the Department of Defense Trauma Registry (DODTR) from January 2007 to August 2016. We only included patients for whom the DODTR specified the hemostatic agent utilized (chitosan or kaolin). We defined a serious injury by body region as an Abbreviated Injury Score (AIS) of 3 or greater. Results: Our predefined search codes captured 28,222 patients. Of those, 258 (0.9%) patients had documented hemostatic use: 58 chitosan, 201 kaolin, and one subject received both. Patients undergoing hemostatic agent application were more likely to be injured by gunshot wound or explosive. Patients with hemostatic application had higher median composite Injury Severity Scores (10 vs. 9, p < 0.001), and higher AIS for the abdomen, extremity and superficial body regions with higher rates of blood product utilization. Proportions of patients suffering traumatic amputations and undergoing tourniquet application were higher in the hemostatic agent group than the baseline population (11.6% vs. 6.7%, p = 0.002 and 43.4% vs. 13.8%, p < 0.001, respectively). Conclusions: Hemostatic agents were infrequently utilized to manage traumatic hemorrhage during the recent conflicts in Afghanistan and Iraq. Hemostatic agent use was more frequent in casualties with gunshot wounds, traumatic amputations, concomitant tourniquet application, and greater blood product administration.”

Prehospital Analgesia for Pediatric Trauma Patients in Iraq and Afghanistan

Abstract Background: Previous studies have evaluated prehospital analgesia during combat operations in Iraq and Afghanistan, but were limited to the adult population. However, a significant portion of the casualties of those conflicts were children. We describe the prehospital analgesia administered to wartime pediatric trauma patients. Methods: We queried the Department of Defense Trauma Registry (DODTR) for all pediatric patients (<18 years of age) admitted to United States and Coalition fixed-facility hospitals in Iraq and Afghanistan from January 2007 to January 2016. We divided pediatric patients into 2 groups: those that had documentation of receipt of analgesic drugs in the prehospital setting (n = 618) and those who had not received analgesia before reaching a fixed-facility (n = 2,821). For characterization of drug administration, we grouped patients into those receiving acetaminophen, NSAID, fentanyl, ketamine, morphine, or other analgesics (e.g., hydromorphone, tramadol, etc.). Results: During the study period, there were 3,439 pediatric encounters with documentation of 703 instances of analgesia administrations to 618 patients (17.9% of total pediatric encounters). Of the subjects receiving analgesic agents, 46.2% (n = 325) received morphine, 30.4% (n = 214) received fentanyl, 17.4% (n = 122) received ketamine, 1.8% (n = 13) received acetaminophen, and 2.8% (n = 20) received a non-steroidal anti-inflammatory drug. The remaining 9 administrations consisted of methoxyflourane (1), nalbuphine (2), hydromorphone (3), and tramadol (3). An injury severity score (ISS) >15 increased the odds of receiving an analgesic agent (OR 1.26, 95% CI 1.02–1.56). Additionally, there was an association between analgesia administration and the following prehospital interventions: wound dressing, tourniquet, intravenous (IV) line placement, intraosseous line placement, IV fluids, intubation, and external warming. Conclusions: Overall, a low proportion of pediatric trauma subjects within this population received analgesia in the prehospital environment. The most common analgesic medication administered was morphine. Those receiving analgesic agents had more severe injuries and higher rates of concomitant interventions. These results highlight the potential need for Tactical Combat Casualty Care guidelines specifically providing recommendations for analgesia administration among pediatric patients.

Self-reported dietary supplement use in deployed United States service members pre-deployment vs . during deployment, Afghanistan, 2013–2014

BackgroundDietary supplement use (protein/amino acids, weight-loss supplements, performance enhancers) is common among U.S. military members. Reported dietary supplement use in deployed troops is limited and is of concern in settings where troops are exposed to high ambient temperatures, increased physical demands, and dehydration. Our objective was to describe dietary supplement use and adverse events (AEs) among deployed U.S. service members compared with their pre-deployment use.MethodsWe conducted an institutional review board (IRB) approved, descriptive study in Afghanistan using a written questionnaire and collected demographic information, dietary supplement use before and during deployment, AEs associated with supplement use, and physical workout routines. Participants were U.S. military personnel of all branches of service deployed to Afghanistan. They were recruited in high-traffic areas in the combat theater. We analyzed the data with descriptive statistics. Paired t-test/Wilcoxon signed-rank test was conducted to examine the before/during deployment changes for continuous data, and McNemar’s chi-square test was conducted for categorical data. We constructed separate logistic regression models to determine the best predictors of increases or decreases in dietary supplement use, with demographic information, reasons for using supplements, and education requested/received as covariates in each model. All statistical tests were two-sided at a significance level of 5% (Pxa0<xa00.05).ResultsData were collected on 1685 participants. Ninety-seven of the participants were in the Army or Air Force.The participants were more likely to work out daily or more than once a day during deployment. Thirty-fivexa0percent of the participants reported no supplement use before or during deployment. The remaining 65% of participants reported increased use and increased frequency of use of supplements (e.g., daily) during deployment compared with pre-deployment. Additionally, more people followed label instructions strictly during deployment vs. pre-deployment.Overall, the frequency of self-reported AEs among supplement users remained consistent before and during deployment. The only significant difference noted was in problems falling or staying asleep, which increased during deployment. In the adjusted logistic regression models, the level of formal education, military branch, occupational specialty, education about dietary supplements, and certain reasons for using supplements (to boost energy, lose weight, gain muscle strength and mass, and as a meal replacement) were significant predictors of changes in supplement use.ConclusionDeployed U.S. service members were more likely to use dietary supplements, use more than one supplement and use supplements more frequently during deployment than pre-deployment. No serious AEs were reported, but problems falling or staying asleep increased during deployment.
