Predictors of High Resource Consumption in Alcohol Intoxicated Patients in the Emergency Department.

Background: previous studies have reported that the incidence of alcohol-related visits to emergency departments (ED) has increased, but little is known about how the necessary resources per visit have changed, or about the predictors and reasons for resource consumption. Methods: a retrospective analysis was performed of all consultations with a primary or secondary diagnosis of acute alcohol intoxication admitted to the ED of Bern University Hospital, Switzerland, between 1 June 2012, and 31 May 2017. Clinical characteristics and resource consumption were extracted and analysed over time. Results: in all, 196,045 ED consultations included 2586 acute alcohol intoxications, corresponding to 1.3% of the total. The incidences of acute alcohol intoxications have tended to increase over the last five years, and a growing number of visits have consumed high resources (consultations above the 75th percentile for total resource consumption). High resource consumption was associated with greater age and the male gender (p < 0.001). The main predictors of resource consumption were fractures (Odds ratio (OR): 3.9, 95% CI 2.8-5.3, p < 0.001), dislocations (OR 3.7, 95%: 1.5-9.1, p < 0.001), and traumatic brain injury (3.5, 2.5-5.1, p < 0.001). Consultations consuming high resources mostly required radiology resources (45%); consultations consuming low or normal resources mostly required physicians' work (45%) or nurses' work (27%). Conclusions: the number of alcohol intoxications consuming high resources has increased over the last five years. Acute alcohol intoxication associated with trauma is resource intensive, especially with regard to radiology resources. This underlines the need for further efforts to prevent alcohol-related traffic accidents, for examples.

Intubation in acute alcohol intoxications at the emergency department.

BACKGROUND: Guidelines recommend endotracheal intubation in trauma patients with a Glasgow coma scale (GCS) < 9 because of the loss of airway reflexes and consequential risk of airway obstruction. However, in patients with acute alcohol intoxication guidelines are not clear. Thus, we aimed to determine the proportional incidence of intubation in alcohol intoxication and compare the clinical characteristics of intubated and non-intubated patients, as well as reasons for intubation in all patients and in the subgroup of patients with reduced GCS (< 9) but without traumatic brain injury. METHODS: We performed a retrospective analysis of all consultations to an urban ED in Switzerland that presented with an acute alcohol intoxication between 1st June 2012 and 31th Mai 2017. Patient and emergency consultations' characteristics, related injuries, intubation and reason for intubations were extracted. As a subgroup analysis, we analysed the patients with a GCS < 9 without a traumatic brain injury. RESULTS: Of 3003 consultations included from 01.06.2012 to 31.05.2017, 68 were intubated, leading to a proportional incidence of 2.3% intubations in alcohol-intoxication. Intubated patients had a lower blood alcohol concentration (1.3 g/kg [IQR 1.0-2.2] vs. 1.6 g/kg [IQR1.1-2.2], p = 0.034) and less often suffered from chronic alcohol abuse (1183 [39.4%] patients vs. 14 [20.6%], p = 0.001) than non-intubated patients. Patients with trauma were intubated more often (33 patients [48.5%] vs. 742 [25.3%], p < 0.001). In subgroup analysis, 110/145 patients (74.3%) were not intubated; again, more intubated patients had a history of trauma (9 patients [25.7%] vs. 10 [9.1%], p = 0.011). CONCLUSIONS: Intubation in alcohol-intoxicated patients is rare and, among intoxicated patients with GCS < 9, more than two thirds were not intubated in our study - without severe complications. Trauma in general, independent of the history of a traumatic brain injury, and a missing history of chronic alcohol abuse are associated with intubation, but not with blood alcohol concentration. Special caution is required for intoxicated patients with trauma or other additional intoxications or diseases.

Acute and mixed alcohol intoxications in asylum seekers presenting to an urban emergency department in Switzerland.

BACKGROUND: Previous studies have reported an increase in alcohol-and-mixed intoxication (AAMI)-related emergency department (ED) admissions, but less is known about the incidence and characteristics of AAMI admissions to EDs among asylum-seeking patients. Asylum seeking patients may be at higher risk for AAMI due stressors associated with forced migration. The aim of this study was to determine the proportional incidence, population characteristics, and predictors of ED admissions due to AAMI among patients with a residency status of asylum seeker as compared to those with a residency status of Swiss-national. METHODS: This retrospective analysis included all medical consultations from a large, adult ED in Switzerland between January 1, 2013 to December 31, 2016. The residency status of consultations was established if possible, and AAMI was determined utilizing a two-step screening procedure, blinded for residency status. A multivariable logistic regression was performed to determine the odds of AAMI in asylum-seeking patient consultations compared to consultations for Swiss-national patients. In addition, patient characteristics among asylum seekers admitted for AAMI were compared to patients with Swiss-national residency status for AAMI. RESULTS: In total, 117,716 eligible consultations (Swiss-national patient consultations: n = 115,226 and asylum-seeker consultations: n = 2490) were included in this study. The proportional incidence of AAMI among asylum seekers was 3.7% (n = 92) compared to 1.6% (n = 1841) among the Swiss-national patients. AAMI in asylum seekers was associated with higher levels of trauma (37.0% vs. 23.5%, p = 0.003), and hospital admission (35.4% vs. 14.1%, p < 0.001), but a smaller proportion of chronic alcohol consumption (13.0% vs. 43.5%, p < 0.001), and psychiatric referrals (26.1% vs. 49.0%, p < 0.001). Multivariable analysis controlling for age, sex, triage category, weekend admission, year of admission, and multiple visits showed a 1.6 times higher odds (95% CI: 1.3, 2.0; p < 0.001) for an AAMI-related ED consultation in asylum seeking patients. CONCLUSIONS: These findings show that individuals seeking asylum in a high-income country may be at greater risk for AAMI-related admission than the local population. Given the observed association between AAMI-related ED admissions and trauma, suicidality, and psychiatric referrals among this subpopulation, the data also suggests that co-morbid mental health disorders associated with forced displacement may contribute to hazardous alcohol use.
