Alcohol and nonlethal injuries: a Swiss emergency department study on the risk relationship between acute alcohol consumption and type of injury

Cannabis presentations to the emergency department after MVC in the era of legalization for recreational use

INTRODUCTION

The objectives of this study were to examine cannabis and alcohol use among injured patients presenting to emergency departments (ED) in cannabis-legal states to capture an expanded profile of cannabis use and evaluate differences in motor-vehicle collision (MVC) characteristics among those using cannabis alone and in combination with alcohol.

METHODS

This was a cross-sectional study of ED visits by drivers in MVC who presented to one of three study sites. Event-related and usual drug and alcohol use information were obtained using a detailed interviewer-administered computerized questionnaire. We also obtained data from blood and breathalyzer tests and the electronic medical record. We examined frequency and types of acute and past-year cannabis and alcohol use and crash mechanisms and characteristics. Our primary method of determining substance use was self-report; we used biosamples secondarily.

RESULTS

Eight percent of drivers reported cannabis use in the 8 h prior to MVC, alone or in combination with alcohol; however, a higher proportion (18%) were positive by biosample. High-risk crash features were common in MVCs associated with cannabis, as they were for alcohol use and co-use of cannabis and alcohol; however, patients injured seriously enough to require admission were less likely to report cannabis use (7% vs. 9%) and more likely to report alcohol use (16% vs. 10%).

CONCLUSIONS

Cannabis use was common among patients presenting after MVC in this sample of cannabis-legal states. Practical Applications: Differences between self-report and biosample data for cannabis and alcohol use were significant and supports the need to use both means of assessing acute use.

Frequency of Recidivism in Patients With Orthopedic Trauma

The goals of this study were to determine the frequency of trauma recidivism and to identify risk factors. The authors hypothesized that substance abuse and mental illness would be associated with recidivism. They performed a retrospective review of 879 patients who were treated surgically for high-energy fractures over a period of 4 years. Recidivism was defined as presentation to the trauma center for a new, unrelated injury. A recurrent recidivist was a repeat patient who returned for more than 1 additional injury. The study identified 164 (18.7%) patients who returned with a new injury. Mean age of recidivists was 37.1 years vs 40.7 years for nonrecidivists (P=.025). Of the recidivists, 80% were male, and this group was more likely to be unmarried (76.2% vs 67.2%, P=.044) and unemployed (40.4% vs 19.6%, P<.0001). Recidivists were also more likely to be uninsured (33.5% vs 17.8%, P<.0001) or to have Medicaid coverage (33.5% vs 23.2%, P<.0001). Recidivists were more likely to have used alcohol (47.2% vs 32.0%, P=.0007) or to be intoxicated (32.4% vs 21.2%, P=.005) and to use tobacco (66.2% vs 50.2%, P=.0003) or recreational drugs (59.1% vs 43.2%, P=.0004) at baseline. The rate of documented mental illness was also higher in repeat patients than in nonrepeat patients (28.1% vs 20.0%, P=.03). These findings showed that recidivism is common, occurring overall in 18.7% of the study sample within a mean of 2.9 years. Factors associated with recidivism included age younger than 40 years, unmarried status, substance use, unemployment, and lack of insurance coverage. The greatest independent risk factors for recidivism were Medicaid insurance or no insurance and a history of a gunshot wound or assault. [Orthopedics. 2016; 39(5):300-306.].

Acute Alcohol Use and Injury Patterns in Young Adult Prehospital Patients

The objective was to determine if acute alcohol consumption is associated with differences in injury pattern among young adult patients with traumatic injuries presenting to emergency medical services (EMS). A cross-sectional, retrospective review of prehospital patient care reports (PCRs) was conducted evaluating injured patients who presented to a collegiate EMS agency from January 1, 2011 to December 31, 2012. Included patients were age 18-24 y and sustained an injury within the previous 24 h. PCRs were reviewed independently by two abstractors to determine if the patient was documented to have acutely consumed alcohol proximate to his/her injury. Primary and secondary sites of regional body injury were recorded. Injury severity was recorded using the Revised Trauma Score (RTS). The association between primary injury site and acute alcohol use was assessed using a chi-square test. Multiple logistic regression was used to control for sex in predicting injury type. Of 440 injured patients, 135 (30.6%) had documented alcohol use prior to injury. Acute alcohol consumption altered the overall pattern of regional injury (p < 0.001). Alcohol users were more likely to present with injury secondary to assault, fall/trip, and unknown mechanism of injury (p < 0.001, all comparisons). RTS scores were statistically lower in the alcohol group (p < 0.001), although the clinical significance of this is unclear. Controlling for sex, acute alcohol consumption predicted increased risk of head/neck injury 5.59-fold (p < 0.001). Acute alcohol use in collegiate EMS patients appears to alter injury patterns in young adults and increases risk of head/neck injury. EMS providers in similar agencies should consider these trends when assessing and treating injured college-aged patients.

Use of psychoactive substances in persons with spinal cord injury: a literature review

OBJECTIVE

To undertake a critical review of literature on use of legal and illegal psychoactive substances (PAS) in persons with spinal cord injury (SCI) before and after trauma.

MATERIAL AND METHODS

Hundred and five articles published between 1980 and 2014 on alcohol and drug use in persons with SCI before and after trauma were retrieved from the PubMed and PsycInfo search engines.

RESULTS

Before injury, 25% to 96% of people with SCI reported using alcohol, while 32% to 35% had used illegal drugs. At the time of injury, 31% to 50% of individuals with SCI were intoxicated with alcohol, 16% to 33% with drugs and 26% with a combination of drugs and alcohol. Among those reporting PAS use before injury, up to 50% stated that they had reduced their use during active rehabilitation, during which time only 6% consumed psychoactive substances for the first time. A variety of risk factors are associated with consumption subsequent to spinal cord injury: personality alteration (impulsiveness, aggressiveness), posttraumatic depression, poor coping skills, lack of social support and pain. PAS use can affect the process of rehabilitation, diminish the effectiveness of medication and result in various medical complications.

DISCUSSION/CONCLUSIONS

Few studies have explored the use of alcohol, drugs and psychoactive medications before SCI and during active rehabilitation. To our knowledge, no study has analyzed the evolution of PAS use after hospital discharge, even though return home is associated with new stressors that may trigger risky behaviors. It should be a priority, as early as possible during rehabilitation, to detect persons at risk of developing PAS abuse.

Alcohol environment, gender and nonfatal injuries in young people. An ecological study of fourteen Swedish municipalities (2000–2005)

Background

Sweden has had a restrictive alcohol policy, but there are gender and geographical differences in alcohol consumption and injury rates within the country. Whether and how the Swedish alcohol environment influences gender differences in injuries in young people is still unclear. Thus, the aim of this study was to analyse the associations between the local alcohol environment and age- and gender-specific nonfatal injury rates in people up to 24 years in Sweden.

Methods

The local alcohol environment from 14 municipalities was studied using indicators of alcohol access, alcohol consumption and alcohol-related crimes. A comprehensive health care register of nonfatal injuries was used to estimate mean annual rates of nonfatal injuries by gender and age group (2000–2005). Pearson’s correlation coefficients were used to analyse linear associations.

Results

Associations were shown for both alcohol access and alcohol consumption with injury rates in boys aged 13–17 years; no other associations were observed between alcohol access or per capita alcohol consumption and nonfatal childhood injuries. The prevalence of crimes against alcohol laws was associated with injury rates in children of both genders aged 6–17 years.

Conclusions

This study found no strong area-level associations between alcohol and age and gender specific nonfatal injuries in young people. Further, the strength of the area-level associations varied by age, gender and type of indicator used to study the local alcohol environment.

Substance use, depression, and mental health functioning in patients seeking acute medical care in an inner-city ED

The study investigated the behavioral health of a consecutive sample of 5,641 adult emergency department (ED) patients aged 19 through 60 presenting for medical care in a large, inner-city hospital ED. Twenty-three percent met the criteria for major depression; average mental health functioning, as measured by the mental health component of the SF-12, was half of a standard deviation lower than in the general population; 15% met the criteria for alcohol or drug abuse/dependence in the past year. Comorbidity was high. These behavioral health disorders may complicate treatment and diagnosis of the chief presenting complaint. These findings, coupled with the high rates of these disorders, suggest the importance of screening and either beginning appropriate treatment or offering appropriate referral for such disorders in ED settings.

The more you drink, the harder you fall: a systematic review and meta-analysis of how acute alcohol consumption and injury or collision risk increase together

Alcohol consumption causes injury in a dose-response manner. The most common mode of sustaining an alcohol-attributable injury is from a single occasion of acute alcohol consumption, but much of the injury literature employs usual consumption habits to assess risk instead. An analysis of the acute dose-response relationship between alcohol and injury is warranted to generate single occasion- and dose-specific relative risks. A systematic literature review and meta-analysis was conducted to fill this gap. Linear and best-fit first-order model were used to model the data. Usual tests of heterogeneity and publication bias were run. Separate meta-analyses were run for motor vehicle and non-motor vehicle injuries, as well as case-control and case-crossover studies. The risk of injury increases non-linearly with increasing alcohol consumption. For motor vehicle accidents, the odds ratio increases by 1.24 (95% CI: 1.18-1.31) per 10-g in pure alcohol increase to 52.0 (95% CI: 34.50-78.28) at 120 g. For non-motor vehicle injury, the OR increases by 1.30 (95% CI: 1.26-1.34) to an OR of 24.2 at 140 g (95% CI: 16.2-36.2). Case-crossover studies of non-MVA injury result in overall higher risks than case-control studies and the per-drink increase in odds of injury was highest for intentional injury, at 1.38 (95% CI: 1.22-1.55). Efforts to reduce drinking both on an individual level and a population level are important. No level of consumption is safe when driving and less than 2 drinks per occasion should be encouraged to reduce the risk of injury.

Impact of Elevated per Cent Carbohydrate-deficient Transferrin at Hospital Admission on Outcomes in Trauma Patients

Chronic alcohol consumption has been linked to increased morbidity and mortality in the intensive care unit setting. The purpose of our study was to assess outcomes in trauma patients admitted to our institutional university-affiliated, Level I emergency trauma unit (ETU) with and without per cent carbohydrate-deficient transferrin (%CDT) elevations over a 12-week timeframe. Markers for alcohol consumption including %CDT, gamma glutamyl transferase, and serum osmolality were measured along with the standard trauma laboratory panel on arrival to the ETU. Intensive care unit length of stay (LOS), length of time requiring ventilator support, hospital LOS, total hospital charges as well as incidences of postoperative complications were collected on all patients with a LOS greater than or equal to 48 hours. Demographics between the groups were similar. Drinking histories were more significant in the elevated %CDT group ( P = 0.0006). Patients with elevated %CDT had significantly longer ICU and hospital LOS (5.1 vs 3.9, P = 0.01; 8.7 vs 7.1 days, P = 0.0052) and ventilator days (2 vs 1.5 days, P = 0.0286). Complications and hospital charges were similar between groups. Trauma patients presenting to the ETU with %CDT elevations appear to be at risk for longer ICU and hospital LOS.

Deadly partners: interdependence of alcohol and trauma in the clinical setting

Trauma is the leading cause of death for Americans aged 1 to 45. Over a third of all fatal motor vehicle collisions and nearly eighty percent of completed suicides involve alcohol. Alcohol can be both a cause of traumatic injury as well as a confounding factor in the diagnosis and treatment of the injured patient. Fortunately, brief interventions after alcohol-related traumatic events have been shown to decrease both trauma recidivism and long-term alcohol use. This review will address the epidemiology of alcohol-related trauma, the influence of alcohol on mortality and other outcomes, and the role of prevention in alcohol-related trauma, within the confines of the clinical setting.
