Alcohol and the adolescent trauma population

Alcohol is not associated with increased mortality in adolescent traumatic brain injury patients

PURPOSE

Compared to adults, there is a paucity of data regarding the association of a positive alcohol screen (PAS) and outcomes in adolescent patients with traumatic brain injury (TBI). We hypothesize adolescent TBI patients with a PAS on admission to have increased mortality compared to patients with a negative alcohol screen.

METHODS

The 2017 Trauma Quality Improvement Program database was queried for patients aged 13-17 years presenting with a TBI and serum alcohol screen. Patients with missing information regarding midline shift on imaging and Glasgow Coma Scale (GCS) score were excluded. A multivariable logistic regression analysis for mortality was performed.

RESULTS

From 2553 adolescent TBI patients with an alcohol screen, 220 (8.6%) had a PAS. Median injury severity scores and rates of penetrating trauma (all p > 0.05) were similar between alcohol positive and negative patients. Patients with a PAS had a similar mortality rate (13.2% vs. 12.1%, p = 0.64) compared to patients with a negative screen. Multivariate logistic regression controlling for risk factors associated with mortality revealed a PAS to confer a similar risk of mortality compared to alcohol negative patients (p = 0.40).

CONCLUSION

Adolescent TBI patients with a PAS had similar associated risk of mortality compared to patients with a negative alcohol screen.

Neonatal temperament and neuromotor differences are predictive of adolescent alcohol intake in rhesus monkeys (Macaca mulatta)

Identifying predictors of teenage alcohol use disorder (AUDs) is a major health initiative, with studies suggesting that there are distinct personality-related traits that underlie patterns of alcohol intake. As temperament is biologically based, identifiable early in life, and stable across time, it is considered the foundation of personality. As such, we hypothesized that neonatal temperament traits would predict anxiety-mediated adolescent alcohol consumption. To test this, N = 145 rhesus macaque (Macaca mulatta) infants (14 days of age), reared in a neonatal nursery (n = 82) or in a control condition with their mothers (n = 63) were assessed with a widely used standardized nonhuman primate testing battery, the Infant Behavioral Assessment Scale (IBAS), modeled after the Brazelton Neonatal Assessment Scale, evaluating visual orienting, temperament, motor maturity and, more recently, sensory sensitivity. As adolescents (3-4 years of age), these same subjects were allowed unfettered access to a sweetened-alcohol solution for 1 hr/day, 4 days/week, over 5-7 weeks. Subjects were allowed to self-administer alcohol while housed alone (n = 70) or socially in their home cage (n = 55). Linear regressions showed that alcohol intake was predicted by neonatal orienting ability (β = -.35; p = .01), state control (β = -.19; p = .04), and motor maturity (β = -.24; p = .01). Poor neonatal orienting, state control (ease of consolability), and motor maturity were associated with higher adolescent alcohol intake in rhesus monkeys. These findings suggest that neonatal temperament is predictive of patterns of adolescent alcohol intake. To the extent that these results generalize to humans, they provide evidence that early-life temperament and neurodevelopment may be important risk factors for adolescent AUDs and that the IBAS may be used as an assessment tool for identifying such risk.

Outcomes and resource utilization associated with underage drinking at a level I trauma center

PURPOSE

To examine the association of blood alcohol content (BAC) on hospital-based outcomes and imaging utilization for patients <21 years admitted to a level I trauma center.

METHODS

Retrospective analysis of alcohol-involved injuries in patients 13-20 years, admitted to a level I trauma center from 1996 to 2010. An injury was considered alcohol involved if the patient had a BAC > 0. Multivariable logistic regression was used to compare mortality, discharge destination (home and skilled nursing facility), intensive care unit admission, and operating room use between patients with and without positive BAC for patients 13-15, 16-17, and 18-20 years. Multivariable linear regression was used to compare length of hospitalization. Finally, multivariable negative binomial regression evaluated radiology resource utilization (x-ray, computed tomography [CT], and magnetic resonance imaging).

RESULTS

A total of 7,663 patients, 13-20 years old, were admitted over the study period. A positive BAC was reported in 19% of these patients. In general, the presence of alcohol was not associated with mortality rate, length of hospitalization, intensive care unit, and operating room use or discharge status for any age group. However, the presence of alcohol was associated with higher utilization of head (incidence rate ratio [IRR] 1.13, 95% confidence interval [CI] 1.02-1.26), cervical spine (IRR 1.10, 95% CI 1.01-1.22), and thoracic (IRR 1.30, 95% CI 1.05-1.63) CTs in young adults 18-20 years. No differences in CT use were observed in patients 13-15 or 16-17 years.

CONCLUSIONS

Positive BAC was not significantly associated with adverse outcomes or resource utilization in younger trauma patients. However, the use of certain body region CTs was associated with positive BAC in patients 18-20 years.

Alcohol and trauma--in every age group

BACKGROUND

The purpose was to determine the proportion of alcohol-positive (AlcPos) trauma patients in different age groups and any association with mortality using the National Trauma Data Bank.

METHODS

Several variables were extracted from the National Trauma Data Bank (version 6.2) using MS Access 2007: age, alcohol presence, Injury Severity Score (ISS), and discharge status (alive vs dead). Age groups for logistic regression were arbitrarily defined as follows: 0 to 10, 11 to 20, 21 to 39, 40 to 64, and older than 64 years.

RESULTS

Approximately 47% of all trauma survivors were tested for alcohol (621,174 of a total of 1,311,137), and 28% of those were AlcPos (176,107/621,174). The proportion of AlcPos patients gradually increased to maximum at 22 years, when 46% (6797/14,732) tested were AlcPos. The proportion AlcPos gradually declined to 35% by age 50 years, then to 15% (2516/16,244) by age 66 to 70 years. The ISSs were significantly higher in AlcPos patients in all age groups (P < .01). Mortality rates were higher in AlcPos children (up to age 20 years) and in adults older than 40 years. The AlcPos patients who were 21 to 39 years old had lower mortality compared with alcohol-negative patients. Logistic regression analysis (controlling for ISSs) revealed that being AlcPos did not play a role in mortality until age 21 to 39 years (AlcPos lower mortality) and in age 40 to 64 years and older than 65 years (AlcPos higher mortality).

CONCLUSIONS

Trauma patients of all ages may be AlcPos. Being AlcPos is a marker for greater injury in all age groups. After controlling for ISSs, trauma patients 40 years and older who were AlcPos have increased mortality. This study suggests a role for alcohol testing in all age groups.

Predictors of binge drinking in adolescents: ultimate and distal factors - a representative study

BACKGROUND

As epidemiological surveys have shown, binge drinking is a constant and wide-spread problem behavior in adolescents. It is not rare to find that more than half of all adolescents engage in this behavior when assessing only the last 4 weeks of time independent of the urbanity of the region they live in. There have been several reviews on predictors of substance consumption in adolescents in general, but there has been less high quality research on predictors of binge drinking, and most studies have not been theoretically based. The current study aimed to analyze the ultimate and distal factors predicting substance consumption according to Petraitis' theory of triadic influence. We assessed the predictive value of these factors with respect to binge drinking in German adolescents, including the identification of influence direction.

METHODS

In the years 2007/2008, a representative written survey of N = 44,610 students in the 9th grade of different school types in Germany was carried out (net sample). The return rate of questionnaires was 88% regarding all students whose teachers or school directors had agreed to participate in the study. In this survey, prevalence of binge drinking was investigated as well as potential predictors from the social/interpersonal, the attitudinal/environmental, and the intrapersonal fields (3 factors of Petraitis). In a multivariate logistic regression analysis, these variables were included after testing for multicollinearity in order to assess their ability to predict binge drinking.

RESULTS

Prevalence of binge drinking in the last 30 days was 52.3% for the surveyed adolescents with a higher prevalence for boys (56.9%) than for girls (47.5%). The two most influential factors found to protect against binge drinking with p < .001 were low economic status and importance of religion. The four most relevant risk factors for binge drinking (p < .001) were life-time prevalence of school absenteeism/truancy, academic failure, suicidal thoughts, and violence at school in the form of aggressive behavior of teachers. The model of Petraitis was partly confirmed for Binge Drinking in German adolescents and the direction of influence factors was clarified.

CONCLUSIONS

Whereas some of the risk and protective factors for binge drinking are not surprising since they are known for substance abuse in general, there are two points that could be targeted in interventions that do not focus on adolescents alone: (a) training teachers in positive, reassuring behavior and constructive criticism and (b) a focus on high risk adolescents either because they have a lack of coping strategies when in a negative mood or because of their low academic achievement in combination with absenteeism from school.

Alcohol consumption and binge drinking in adolescents: comparison of different migration backgrounds and rural vs. urban residence--a representative study

Background

Binge drinking is a constant problem behavior in adolescents across Europe. Epidemiological investigations have been reported. However, epidemiological data on alcohol consumption of adolescents with different migration backgrounds are rare. Furthermore representative data on rural-urban comparison concerning alcohol consumption and binge drinking are lacking. The aims of the study are the investigation of alcohol consumption patterns with respect to a) urban-rural differences and b) differences according to migration background.

Methods

In the years 2007/2008, a representative written survey of N = 44,610 students in the 9^th. grade of different school types in Germany was carried out (net sample). The return rate of questionnaires was 88% regarding all students whose teachers respectively school directors had agreed to participate in the study. Weighting factors were specified and used to make up for regional and school-type specific differences in return rates. 27.4% of the adolescents surveyed have a migration background, whereby the Turkish culture is the largest group followed by adolescents who emigrated from former Soviet Union states. The sample includes seven large cities (over 500,000 inhabitants) (12.2%), independent smaller cities ("urban districts") (19.0%) and rural areas ("rural districts") (68.8%).

Results

Life-time prevalence for alcohol consumption differs significantly between rural (93.7%) and urban areas (86.6% large cities; 89.1% smaller cities) with a higher prevalence in rural areas. The same accounts for 12-month prevalence for alcohol consumption. 57.3% of the rural, re-spectively 45.9% of the urban adolescents engaged in binge drinking in the 4 weeks prior to the survey. Students with migration background of the former Soviet Union showed mainly drinking behavior similar to that of German adolescents. Adolescents with Turkish roots had engaged in binge drinking in the last four weeks less frequently than adolescents of German descent (23.6% vs. 57.4%). However, in those adolescents who consumed alcohol in the last 4 weeks, binge drinking is very prominent across the cultural backgrounds.

Conclusions

Binge drinking is a common problem behavior in German adolescents. Obviously adolescents with rural residence have fewer alternatives for engaging in interesting leisure activities than adolescents living in cities. This might be one reason for the more problematic consumption patterns there. Common expectations concerning drinking behavior of adolescents of certain cultural backgrounds ('migrants with Russian background drink more'/'migrants from Arabic respectively Oriental-Islamic countries drink less') are only partly affirmed. Possibly, the degree of acculturation to the permissive German alcohol culture plays a role here.

Adolescent orofacial injury: association with psychological symptoms

Ethnic minority youth living in urban areas experience disproportionately high rates of violent intentional injuries. This study investigates the association of violent intentional injuries with psychological distress and alcohol use among adolescents treated in trauma centers for facial injuries. Interviews were conducted with 67 adolescents treated at two urban trauma centers (predominantly males [86%], and minority [Latino, 72%; African American, 19%]). Adolescents reported experiencing several different types of accidental and assault-related injuries that required medical attention in the past six months. About half (53%) reported experiencing only unintentional injuries (e.g. car accidents, falls, sports injury); 23% experienced one type of intentional injury resulting from either fighting or being attacked; and 24% experienced two types of intentional injuries resulting from both fighting and being attacked. Measures of alcohol use and psychological distress were examined in relation to these three types of injuries. Overall, 30% of study participants reported they had been drinking alcohol at the time of injury. Compared to adolescents without intentional injuries, those who experienced a physical fight and/or attack had higher levels of alcohol problems, depression, paranoia and somatic symptoms, and were more likely to have family members with alcohol problems. There is a considerable need for adolescents with intentional assault-related injuries to be screened for alcohol and mental health problems, and to be referred for appropriate treatment interventions if they score at problem levels.

Substance use and facial injury

Substance use is a major contributing factor to the interpersonal violence that accounts for a significant proportion of facial injuries among adults and adolescents; thus, violence is the main "pathway" through which substance use and injuries are linked. Beyond causality, substance use continues to influence recovery from the injury through its impact on the healing process (eg, patient noncompliance, suppression of T-cell counts, susceptibility to bacterial colonization, and protein production). Further exacerbating this issue are significant rates of injury recidivism and the lack of motivation to seek treatment for underlying substance-use problems. As a frontline care provider, the oral and maxillofacial surgeon has a responsibility to screen and refer patients for any needed specialty treatment (including substance-use treatment, violence reduction, and posttraumatic stress reduction). Recognizing and addressing these issues requires a paradigm shift that involves integration of multidisciplinary expertise.

Factors associated with orofacial injury and willingness to participate in interventions among adolescents treated in trauma centers

PURPOSE

Assault is the most common cause of facial injuries in adolescents treated at inner-city trauma centers, yet little is known about the behavioral and environmental antecedents of these injuries or the willingness of such at-risk adolescents to participate in behavioral interventions to minimize reinjury. The purpose of this study was to identify possible risk and protective factors among adolescents with assault-related facial injury and to assess their willingness to participate in prospective observational research and behavioral interventions.

PATIENTS AND METHODS

Interviews were conducted with 67 adolescents (range 14 to 20 yrs) who were treated in trauma centers for facial injuries. Most of these injuries were assault-related (59%), followed by motor vehicle or other accidents (29%), gunshot wounds (9%), and sports injuries (3%). The subjects were predominantly male (86%) and of ethnic minorities (91%).

RESULTS

The adolescents showed high rates of intentional injuries in the past 6 months (56%), unhealthy alcohol use, and in more than half (55%) problem levels of substance use. Compared with those with unintentional injuries, adolescents who experienced assault-related injuries were more likely to report using alcohol, tobacco, and other substances. Although a significant segment of the sample (55%) had been arrested previously, no differences in arrest rates or types of crimes for which adolescents were arrested were observed by injury type. Most subjects were unwilling to participate in interventions that involved multiple sessions; however, greater family cohesion predicted the likelihood of being willing to participate.

CONCLUSIONS

Most facial injuries in inner-city adolescents result from assault. Unhealthy alcohol use, problem levels of substance use behaviors, and family history of alcohol problems are associated markers of assault-related injuries that can be useful for risk assessment and targeted intervention. Interventions need to be brief if they are to engage these at-risk youth.

Binge drinking in childhood and adolescence: epidemiology, consequences, and interventions

BACKGROUND

Episodic excessive alcohol consumption ("binge drinking") among children and adolescents has become a serious public health problem in Germany and is associated with a variety of risks.

METHODS

Selective literature search of the Ovid Medline database from 1998 to 2008.

RESULTS

Episodic excessive alcohol consumption is associated not only with somatic complications, but also with traffic accidents and other types of accident, violent behavior, and suicide. The more frequently a child or adolescent drinks to excess, and the younger he or she is, the greater is the risk of developing an alcohol-related disorder (alcohol misuse or dependence syndrome). In the USA, brief motivational interventions have been shown to have a small to medium-sized beneficial effect in reducing further binge drinking and its complications.

CONCLUSIONS

The intervention HaLT ("Stop," also an acronym for Hart am Limit--"near the limit") is performed in a number of regions in Germany. Further types of brief motivating intervention should be developed and evaluated to prevent the development of alcohol-related disorders, where indicated, in children and adolescents that engage in binge drinking.

Characterization of the drug-positive adolescent trauma population: should we, do we, and does it make a difference if we test?

PURPOSE

Substance abuse (SA) is a significant cofactor for adolescent injury. Characterization of this population will help define a list of variables that are critical for designing interventions. The purpose of this study is to determine the frequency of SA testing and describe the injury characteristics of the adolescent trauma SA population.

METHODS

A urine drug screening (alcohol, cannabis, and opiates) protocol for all injured adolescents (14-17 years old) was used. Four years of data were analyzed. Three groups were defined: not tested (NT), negative (NEG), and positive (POS). Transfers from an outside hospital and those who received opiate pain medication before drug screening were excluded. A patient may have had more than one positive test. Tests were analyzed to compare sex, injury severity score (ISS), survival, mechanism, and length of stay (LOS).

RESULTS

Four hundred forty-three patients met the criteria (308 males and 135 females). Mean ISS was 13.5 +/- 0.5 SEM with a 2.9% mortality rate. One hundred ninety-three of 443 (44%) were screened (m = 120, f = 73) with 39% testing positive in each group. Twenty-nine percent of positive tests were opiates, 11.2% alcohol, and 20% cannabis. No sex differences for alcohol, cannabis, or opiate use were noted. There were no differences between the NT and the NEG/POS groups with respect to sex, LOS, or mechanism of injury. Fourteen-year olds were less likely to be drug screened. Mean ISS score was lower in the NT group (11.4 +/- 0.6 vs 15.7 +/- 1.0, P< .005). For the NEG and POS group analysis, a positive drug screen was not predicted by age, sex, ISS score, outcome, or LOS. Bicycle crashes were predictive of a positive drug screen (P < .005). Survival rates were not different between any of the groups.

CONCLUSIONS

Forty percent of the patients screened positive, thus, supporting screening in adolescent trauma patients. Selective criteria based on injury characteristics are not justified.

The neurocognitive effects of alcohol on adolescents and college students

BACKGROUND

Adolescents and college students are at high risk for initiating alcohol use and high-risk (or binge) drinking. There is a growing body of literature on neurotoxic and harmful cognitive effects of drinking by young people. On average, youths take their first drink at age 12 years.

METHODS

MEDLINE search on neurologic and cognitive effects of underage drinking.

RESULTS

Problematic alcohol consumption is not a benign condition that resolves with age. Individuals who first use alcohol before age 14 years are at increased risk of developing alcohol use disorders. Underage drinkers are susceptible to immediate consequences of alcohol use, including blackouts, hangovers, and alcohol poisoning and are at elevated risk of neurodegeneration (particularly in regions of the brain responsible for learning and memory), impairments in functional brain activity, and the appearance of neurocognitive deficits. Heavy episodic or binge drinking impairs study habits and erodes the development of transitional skills to adulthood.

CONCLUSIONS

Underage alcohol use is associated with brain damage and neurocognitive deficits, with implications for learning and intellectual development. Impaired intellectual development may continue to affect individuals into adulthood. It is imperative for policymakers and organized medicine to address the problem of underage drinking.

Potential biases in case detection of alcohol involvement among adolescents in an emergency department

OBJECTIVE

To determine the factors associated with physician decisions to test for alcohol involvement in adolescents treated in an emergency department (ED) and to examine patient and event characteristics associated with being identified as alcohol positive, either by testing or by clinical examination.

METHODS

Medical chart reviews were conducted for all adolescent patients (n = 9,660; age range, 13-19 y) treated over a 1-year period in a Level I regional trauma center/ED.

RESULTS

Among all 9,660 patients in the ED, 298 (3.1%) were identified as alcohol positive by test or clinical examination. Of the 9,660 patients, 464 (4.8%) were tested for alcohol, and 49% of these had alcohol-positive test results. Physicians were more likely to order alcohol tests when patients were male, older, injured, and treated during the overnight shift or on weekends. Testing was most common for suicide attempts, motor vehicle crashes, assaults, and intoxication. Patients being treated for an illness or for occupational or athletic injuries were rarely tested. A large proportion of alcohol-related treatment was for intoxicated, uninjured patients, whose profile was different (ie, younger, more often female, with higher blood alcohol concentrations, and admission distributed more evenly across ED shifts).

CONCLUSIONS

Case detection rates for alcohol involvement may be biased and inflated when based on physician decisions to test for alcohol use. Rates based on comprehensive chart reviews and clinical examination may be better estimates but are also subject to methodologic limitations. Universal screening would yield the most accurate estimates of alcohol prevalence and would provide more accurate guidance to physicians regarding when to test for alcohol use. Universal screening as a clinical standard would help to identify more adolescents who might benefit from additional alcohol use intervention.

Social services referral of adolescent trauma patients admitted following alcohol-related injury

Alcohol screening of severely injured patients should be universal. Hospitalization following alcohol-related injury provides an opportunity for intervention to reduce recidivism. This study examines the frequency of social services referral of an alcohol positive cohort of adolescent trauma patients. This was a retrospective analysis of data collected from 1994 through 1998 by the National Pediatric Trauma Registry. All patients between the ages of 12 and 17 who had a blood alcohol level (BAL) measured were analyzed. Patients receiving referral to the department of social services, family counseling, or addiction services, and those receiving any substance abuse education intervention were considered a positive referral. There were 6006 children age 12 to 17 included in the database during this five-year period, 751 of whom had a BAL measured. Of those screened, 15.5% were positive. Sixty-eight (59%) of the BAL positive patients were referred for intervention through social services. The only statistically significant predictor of referral was whether or not the patient was the operator of a vehicle involved in the motor vehicle collision. Nearly half of the adolescents in this study, who screened positive for alcohol, received no social services support.

Alcohol and injury in adolescents

OBJECTIVE

To determine the frequency of alcohol ingestion in adolescent victims of major trauma and determine whether alcohol ingestion is associated with increased injury severity or death.

METHODS

Subjects were all patients between 12-25 years of age treated at Pennsylvania trauma centers in 1996 who were reported to the state trauma database. Data on age, mechanism of injury (E-code), blood alcohol concentration (BAC), Injury Severity Score (ISS), and survival were obtained from the state database. BAC positive and negative patients within three groups: ages 12-17, 18-20, and 21-25, were compared to determine any difference in death rate, injury severity or type of injury.

RESULTS

4309 patients aged 12-25 were reported to the state in 1996. 2724 (63.2%) underwent testing for BAC, with 884 (32.5%) of those tested being positive. Testing positive were: 93/726 (12.8%) between 12-17 years old, 249/844 (29.5%) between 18-20 years old, and 542/1154 (47.0%) between 21-25 years old. 567/884 (64.1%) of those testing positive had BAC > or = 100 mg/dl. There were no statistically significant differences in mean ISS or death rate between BAC negative and BAC positive patients in either of the age groups. Regression analysis also showed no relationship between mortality and either the presence of alcohol or the actual level of BAC. Other regression analysis demonstrated a slight downward trend for ISS with increasing intoxication, which was statistically significant at P < 0.01.

CONCLUSIONS

Alcohol ingestion is found even in early adolescent trauma patients and is seen to increase throughout the teenage years, occurring in over one-quarter of patients 18 to 20 years of age. Suspicion must be high that ingestion of alcohol has occurred in adolescent trauma. Further efforts should be made to improve the rate of testing in late adolescents, to ensure adequate identification of all alcohol-exposed patients and enable educational interventions. No significant differences in mortality were seen between alcohol positive and negative patients, but there was a trend to decreased injury severity with the presence of alcohol.

Adolescent risk taking and self-reported injuries associated with substance use

OBJECTIVE

To examine the incidence of adolescent substance use at the time of injury and its relation to risk-taking behavior.

METHOD

A total of 643 male and 782 female 9th through 12th grade students at three high schools anonymously completed surveys on any injuries that had occurred in the prior 6 months associated with substance use and risk-taking behavior.

RESULTS

Males reported a higher incidence of injuries related to alcohol or other drugs than females (17.3% vs. 13%). The 17 year olds reported more injuries related to substance use than 14 or 15 year olds (20.2% vs. 14.4% and 15%, respectively). A logistic regression analysis revealed that the odds of a substance use-related injury increased approximately sixfold when adolescents reported engaging in risk-taking behavior.

CONCLUSION

A significant portion of adolescents (approximately 15%) reported injuries associated with substance use. Adolescents who reported a history of risk-taking behaviors were much more likely to report substance use-related injuries.

Alcohol and other psychoactive drugs in trauma patients aged 10-14 years

OBJECTIVE

To examine the prevalence of alcohol and/or other psychoactive drugs, such as marijuana and cocaine (AODs), involved in preteen trauma patients.

METHODS

Toxicological testing results were analyzed for 1356 trauma patients aged 10-14 years recorded in the National Pediatric Trauma Registry for the years 1990-95.

RESULTS

Of the 1356 patients who received toxicological screening at the time of admission, 116 (9%) were positive for AODs. AOD involvement increased with age. Patients with pre-existing mental disorders were nearly three times as likely as other patients to be AOD positive (23% v 8%, p < 0.01). AOD involvement was more prevalent in intentional injuries and in injuries that occurred at home.

CONCLUSIONS

AODs in preteen trauma are of valid concern, in particular among patients with mental disorders or intentional injuries. The role of AODs in childhood injuries needs to be further examined using standard screening instruments and representative study samples.

Epidemiology of alcohol-related emergency department visits

OBJECTIVE

To examine the population and geographic patterns, patient characteristics, and clinical presentations and outcomes of alcohol-related ED visits at a national level.

METHODS

Cross-sectional data on a probability sample of 21,886 ED visits from the 1995 National Hospital Ambulatory Medical Care Survey were analyzed with consideration of the individual patient visit weight. The annual number and rates of alcohol-related ED visits were computed based on weighted analysis in relation to demographic characteristics and geographic region. Specific variables of alcohol-related ED visits examined included demographic and medical characteristics, patient-reported reasons for visit, and physicians' principal diagnoses.

RESULTS

Of the 96.5 million ED visits in 1995, an estimated 2.6 million (2.7%) were related to alcohol abuse. The overall annual rate of alcohol-related ED visits was 10.0 visits per 1,000 population [95% confidence interval (CI) 8.7-11.3]. Higher rates were found for men (14.7 per 1,000, 95% CI 12.5-16.9), adults aged 25 to 44 years (17.8 per 1,000, 95% CI 15.0-20.6), blacks (18.1 per 1,000, 95% CI 14.0-22.1), and residents living in the northeast region (15.2 per 1,000, 95% CI 12.1-18.2). Patients whose visits were alcohol-related were more likely than other patients to be uninsured, smokers, or depressive. Alcohol-related ED visits were 1.6 times as likely as other visits to be injury-related, and 1.8 times as likely to be rated as "urgent" or "emergent." The leading principal reasons for alcohol-related ED visits were complaints of pain, injury, and drinking problems. Alcohol abuse/dependence was the principal diagnosis for 20% of the alcohol-related visits.

CONCLUSION

Alcohol abuse poses a major burden on the emergency medical care system. The age, gender, and geographic characteristics of alcohol-related ED visits are consistent with drinking patterns in the general population.

Detection of alcohol use in adolescent patients in the emergency department

OBJECTIVES

To examine 3 methods of detecting alcohol use among adolescent patients visiting a Level-1 regional trauma center.

METHODS

Part 1 was a retrospective review of laboratory records and (13- to 19-year-old) patient medical records over the 1-year period from August 1993 to July 1994. Part 2 was a review of ICD-9 discharge diagnoses for the same age range during the same 1-year period. Part 3 involved prospective saliva alcohol testing of injured patients aged 13-17 years old.

RESULTS

Part 1: A total of 522 blood tests were conducted and 160 (30.6%) were positive for alcohol. More than one-third of the alcohol-positive sample had alcohol ingestion as the only reason for their visits, i.e., they were uninjured. The alcohol-positive group was more likely to be male and older. Part 2: A total of 99 alcohol-related discharge diagnoses were given to adolescent patients. Alcohol abuse was the most common diagnosis. With the 2 methods of detection combined, 186 patients were identified. Part 3: A total of 119 saliva alcohol tests were conducted. One patient tested positive but had been identified while in triage as having used alcohol.

CONCLUSION

In this study population, approximately one-third of adolescent patients tested for alcohol as part of routine clinical care were alcohol-positive but were not necessarily given an alcohol-related diagnosis. Thus, studies determining rates of alcohol-positive adolescents treated in EDs should use multiple methods of detection. Universal testing does not appear to be warranted for all injured adolescent patients.

Relationship between substance use and self-reported injuries among adolescents

High school students (n = 1983), 14-18 years olds, were surveyed regarding the incidence of injury and substance use at the time of the injury in the prior 6 months. Alcohol or other drugs were reported particularly often for falls, cuts, and gun and assault injuries. Alcohol or other drugs were reported to be involved in a substantial proportion of injuries resulting in medical care, most notably for gunshots (70%), pedestrian injuries (42%) and physical fights (38%).

Alcohol use among injured patients aged 12 to 18 years

OBJECTIVE

To examine the scope of alcohol use among a population of injured adolescents.

METHODS

A convenience sample of injured patients aged 12-18 years seen at a pediatric ED was tested for the presence of alcohol. Injured patients seen within 6 hours of their injuries were asked to submit urine samples for testing using reagent strips. Data were collected from the patient, out-of-hospital emergency care personnel, and parents regarding the circumstances of the injury.

RESULTS

Of the 243 injured patients who were tested during an 8-month period, 231 were included in the final analysis. Ninety patients (39%) were alcohol-positive. The mean age of the alcohol-positive group was 16.0 +/- 1.64 years, compared with 15.3 +/- 1.8 years for the alcohol-negative group (p < 0.003). There was no significant difference between the 2 groups based on race, gender, or injury characteristics. A positive urine alcohol test was found for 18 (33%) of motor vehicle crash victims, 9 (38%) of the motor vehicle drivers, 10 (37%) of the patients who attempted suicide, and 49 (44%) of the assault victims.

CONCLUSIONS

A substantial percentage of injured adolescent patients were alcohol-positive. The authors recommend the use of alcohol screening when treating injured adolescents.

Injury type, injury severity, and repeat occurrence of alcohol-related trauma in adolescents

Injury associated with alcohol use is a significant problem among adolescents; however, routine evaluation of alcohol use in this population is not conducted. The purpose of this study was to compare injured adolescents presenting to an emergency room with a positive serum alcohol concentration (SAC+) with those injured adolescents with a negative serum alcohol concentration (SAC-). Data were collected retrospectively on 176 injured patients, between the ages of 13 and 18, consecutively admitted to a university hospital from January 1, 1989-December 31, 1990. Information collected included mechanism and severity of injury, outcome, SAC, length of stay, psychiatric history, prior or subsequent admission for injury, and hospital charges. Of those tested with an SAC, more than one-third had a positive SAC. Patients with positive SACs had a greater probability of having a psychiatric history and more frequently had a prior or subsequent injury. Furthermore, only 34% of SAC+ patients were referred for counseling. The results indicate that a SAC should be obtained on all adolescents admitted for trauma, that adolescents presenting with injuries and a positive SAC should be referred for alcohol and psychiatric assessment, and that injured adolescents may be at increased risk for repeat injuries in the future.

Circulatory response of young adult trauma victims with alcohol intoxication

Young adults are a subgroup particularly susceptible to traumatic injury; alcohol intoxication is a major risk factor for trauma in young adults. During the first hours following multiple trauma, however, little is known about the specific effects of alcohol intoxication on the circulatory response of critically injured young adults. The purpose of this prospective study was to compare the circulatory response of 5 severely injured young adults (15-40 years old) with acute alcohol intoxication to the circulatory response of 5 severely injured, nonintoxicated young adults. Data were collected every hour for the first 8 hours after admission to a surgical intensive care unit. Subjects with alcohol intoxication had significantly higher heart rates (t = 2.8176, p < .05) than their nonintoxicated counterparts. Heart rate and blood pressure, however, showed no statistically significant (p < .05) Group x Time interaction between the two groups. Subjects with alcohol intoxication also had injuries that caused more blood loss, more invasive monitoring, more operative procedures, more fluid replacement, and higher oxygen requirements.
