ABSTRACT
Background: The COVID-19 pandemic has been linked to increased mental health issues and interpersonal violence. Both psychiatric diagnoses and young males are overrepresented in the trauma population. Our objective was to characterize injury characteristics and their relationship to psychiatric diagnoses after the COVID-19 lockdown at a trauma centre in Edmonton, Alberta. Specifically, we queried relationships between gender, age, length of stay and intentionally violent injuries, and we reviewed access to inpatient and outpatient mental health and addiction resources. Method(s): We performed a retrospective chart audit for trauma patients aged 18-64 years admitted to the University of Alberta Hospital Trauma Service from June 1 to Aug. 31, 2020. Variables included demographics, injury characteristics, psychiatric history, substance use disorder history and presence of psychiatry and addictions consultations. Treatment plans and follow-up were assessed. Frequencies and basic descriptives were calculated. Univariate analyses were performed to identify relationships between psychiatric or addiction diagnosis (or both) and injury patterns. Result(s): A total of 176 patients met the inclusion criteria. Patients were young (mean age 39.7 yr) and male (73%), and blunt injury was most common (82%). Sixty-three patients (36%) had a psychiatric (29 patients) or addiction (59 patients) history. Twenty-eight patients (15%) received consults to the psychiatry service. At discharge, follow-up included mental health team (10 patients, 36%), family physician (2 patients, 7%) or self-referral resources (8 patients, 29%). Eight patients were not provided follow-up. Fifty-nine patients (34%) had 1 or more addictions history. Nineteen patients (32%) received consultations to psychiatry (18 patients) or addictions (1 patient). Otherwise, 6 patients (10%) were provided community resources at tertiary survey, 6 patients (10%) declined offered resources and 6 patients (10%) had traumatic brain injury (addiction resources deferred). Twenty-five patients (42%) either were not offered resources or documentation was unclear. On univariate analysis of patients with psychiatry consult, age was similar, but females were more likely to be represented (42% v. 24%, p = 0.06). Average length of stay was 17 days versus 9.7 days (p = 0.05). Having a psychiatric consultation or addictions history (or both) was associated with a violent mechanism of injury (35% v. 18%, p < 0.02). Conclusion(s): Over one-third of trauma patients aged 18-64 years had a psychiatric or addiction history (or both) and were significantly more likely to have a violent injury mechanism. Psychiatric consultation was common, more so in female patients, and linked to increased length of stay. Community follow-up was suboptimal, especially for patients with addiction history. Resource access and provision must be optimized to improve care, reduce recidivism and target interpersonal violence during this time of increased individual and system stress..
ABSTRACT
Background: Alcohol is a major factor in traumatic injuries. Accreditation bodies recommend alcohol screening and intervention programs as trauma quality indicators. Previous research in Alberta reported increasing alcohol use prevalence in major trauma. The COVID-19 pandemic has also been linked to increased alcohol consumption. Our objective was to characterize injury characteristics and their relationship to alcohol use during the summer trauma season after the COVID-19 lockdown, and compliance with alcohol misuse screening, at a level 1 trauma centre in Edmonton, Alberta. Method(s): We conducted a retrospective chart audit for trauma patients aged 18-64 years who were admitted to the University of Alberta Hospital Trauma Service from June 1 to Aug. 31, 2020. Variables included demographics, injury characteristics, ethanol level on presentation, history of substance use and screening or intervention. Tertiary surveys as well as psychiatry and addictions consultations were reviewed to assess compliance with screening and intervention. Frequencies and basic descriptives were calculated. Logistic regression was performed to identify relationships between alcohol use and injury patterns. Result(s): A total of 176 patients met the inclusion criteria. The mean age was 40 (standard deviation [SD] 13.8) years, and 128 (72.7%) were male. Blunt injuries were most common (144 patients [81.8%] had a blunt injury, 27 [15.3%] had a penetrating injury and 3 [1.7%] had a burn), with average Injury Severity Score 13 (1-45) and average length of stay 10.6 (SD 14.6) days. Motor vehicle crashes (MVCs) predominated (66 patients, 37.5%) followed by falls (33 patients, 18.8%), sport-related injuries (30 patients, 17.1%) and stabbings (17 patients, 9.7%). A total of 156 patients (88.6%) had an ethanol level drawn on presentation;50 (32%) were positive, and 33 of these (66%) were legally intoxicated. Forty-five patients (25.6%) had a documented addiction history with alcohol use disorder, 29 of whom presented with a positive ethanol level. Of the 50 patients with elevated ethanol level on presentation, the average age was 36 (SD 12.1) years and the mean ethanol level was 36.9 (SD 23.3) mmol/L. MVCs were the most common mechanism (18 patients, 36%). Screening for alcohol use disorder was performed in 39 (78%) of these 50 patients who presented with a positive ethanol level (unclear documentation in the remainder). Addiction services were offered to 10 of 50 patients (20%). Positive ethanol level was associated with younger age (36 v. 41 yr, p = 0.02). Logistic regression revealed that positive ethanol level was significantly associated with stab mechanism of injury (odds ratio [OR] 3.75, 96% confidence interval [CI] 1.1-11.6, p < 0.05);intoxication further increased association with stab injury (OR 4.4, 95% CI 1.4-15, p < 0.01). Conclusion(s): The prevalence of positive ethanol level in trauma patients is rising: 32% currently, compared with 24% from Alberta 2010 data. Over one-quarter of MVC patients had a positive ethanol level, and intoxication increased the odds of stab injury. Compliance with alcohol misuse screening was 78% with only 20% of patients offered intervention, despite 58% having alcohol use disorder. Interventions to reduce preventable injuries and alcohol misuse at the population and hospital levels are needed..
