The Oregon District Shooting: Reviewing the Pre-Hospital Protocols and the Role of the Resident During a Multiple Casualty Event.

Background: Review of multiple casualty events (MCEs) protocols in an academic trauma center and more importantly role of residents in management of MCEs has not been discussed. Also, no real-world examples have been described. This study reviews utilization of multiple casualty protocols by the area hospitals and EMS along with role of residents in one such real-world MCEMethods: A mass shooting event in the Oregon District in Dayton, Ohio from 2019 was reviewed. MCE protocols from a Level I trauma center were reviewed as well as patient outcomes and role of residents.Results: A total of 10 casualties were observed and 38 patients presented to hospitals throughout the city. There were 25 patients presented to the Level I trauma center, 1 to the Level II trauma center, and 12 to the Level III trauma centers in the community. Surgical and Emergency residents performed initial triage upon arrival to the ED, managed resuscitation, and performed various procedures under supervision of attending staff. A total of 5 patients required emergent surgery and 4 patients required tourniquets. All patients that were presented to the hospitals survived.Conclusion: MCEs are going to continue, and healthcare systems should have protocols in place. Residents are a valuable resource to hospital systems that provide trauma services. Creation of a protocol with the assistance of EMS will allow first responders to utilize resources available. We recommend testing of this protocol, as an MCE in your area may not be a matter of if, but when.

Delayed diagnosis of splenic injuries: A case series.

INTRODUCTION: Injury of the spleen may result in significant morbidity and mortality, often related to blood loss. Splenic injuries may be missed on the initial Emergency Department (ED) presentation. This study was undertaken to describe cases of delayed diagnosis, and to identify factors associated with delayed diagnosis, treatment, and outcomes. METHODS: This retrospective study examined eligible participants with injury to the spleen who were admitted between July 2015-December 2017. Eligible participants included patients age 16 and over with injury to the spleen, with two or more ED presentations prior to admission and inpatient management. Data collected included age, gender, ethnicity, trauma triage category, vital signs, mechanism of injury, CT diagnosis, time from injury to diagnosis, toxicologic test results, inpatient management, outcome, and days of hospitalization. RESULTS: Among 210 patients with splenic injury, the mean age was 36. Most participants were male (N = 132; 63%) and White (N = 165; 79%). A small percentage (6%) was not diagnosed with splenic injury during the initial ED encounter. Missed diagnosis on the initial ED visit was not associated with age, gender, ethnicity, mechanism of injury, vital signs, grade of injury, intervention, or days of hospitalization. Most patients were discharged home (N = 9); a minority died (N = 1) or were discharged to a rehabilitation facility (N = 1). CONCLUSIONS: In this study, 6% of patients with splenic injury were not diagnosed during the initial ED encounter. These patients with delayed diagnosis had similar grade of injury, need for intervention, days of hospitalization, and outcome.

Naloxone Use Among Emergency Department Patients with Opioid Overdose.

BACKGROUND: Emergency department (ED) visits for unintentional opioid overdoses have increased dramatically. Naloxone hydrochloride (Narcan®) is an opioid antagonist commonly used to treat these overdoses. OBJECTIVE: This study was undertaken to identify experiences regarding naloxone use among ED patients with opioid overdose. METHODS: This prospective survey study was conducted at an urban level I trauma center. A survey was administered to eligible ED patients after unintentional opioid overdose. This study identified current and previous use of naloxone among ED patients with opioid overdose. RESULTS: Eight-nine ED patients with accidental overdose of opioids participated (90% participation rate). Most participants reported a history of opioid overdose (n = 62 [70%]). A significant minority stated they have had access to a naloxone kit (n = 28 [31%]). Most participants with a naloxone kit stated that their frequency and dosage of opiate use did not change after access to naloxone (n = 17 [63%]), and a few used opiates more often (n = 1 [4%]) or less often (n = 9 [33%]). There was a significant negative correlation between total dose and age (Spearman ρ -0.27; p = 0.01). There was no association between dose and sex. CONCLUSIONS: Many patients presenting with opioid overdose have had a history of opioid overdose. Patients with opioid overdose required a highly variable dose of naloxone. Higher doses of naloxone were associated with lower age. Despite widespread availability of naloxone to consumers, a minority of patients in this study reported access to naloxone. Participants who had access to a naloxone kit stated that their frequency and dosage of opioid use did not change.

Effects of opioid medications on cognitive skills among Emergency Department patients.

INTRODUCTION: Treatment for pain and related conditions has been identified as the most common reason for Emergency Department (ED) visits. Concerns exist regarding the effects of opioid pain medications on cognition and patient ability to consent for procedures, hospital admission, or to refuse recommended medical interventions. This study was undertaken to identify cognitive skills before and after opioid pain medication in the ED setting. METHODS: This was a prospective study comparing performance on the Mini-Mental Status Examination (MMSE) and Montreal Cognitive Assessment (MoCA) before and after administration of opioid pain medications. Eligible participants included ED patients with pain, who received opioid treatment. Participants were randomized to receive either the MMSE before pain medication and the MoCA after medication, or the reverse. MoCA scores were converted to MMSE equivalent scores for comparison. RESULTS: Among 65 participants, the median age was 36 and median triage pain score was 8. 35% of patients were considered cognitively impaired based on their MMSE score prior to any opioid medication (MMSE<27). There was a median decrease in pain scores of 1 point following pain medication, p-value<0.001. There was a median decrease in MMSE scores of 1 point following pain medication, p-value=0.003. The range of change in scores (post minus pre) on the MMSE-equivalent was -7 to 3. 35 patients (56%) had a decrease in scores, 6 (10%) had no change, and 21 (34%) had an increase. After medication, 31 (48%) were abnormal (MMSE score<27). No differences in MMSE scores were identified by gender, ethnicity, mode of arrival, insurance, age, triage pain scores, opioid agent given, or ED diagnosis. CONCLUSIONS: There is an association between opioid pain medication and decrease in cognitive performance on the MMSE. Because of the wide range of cognitive performance following opioid pain medication, assessment of individual patients' cognitive function is indicated.
