The purpose of this paper is to better understand marijuana use among injured problem drinkers in the emergency department (ED). The specific objectives are: 1) to assess the prevalence of marijuana use; 2) to identify factors associated with marijuana use; 3) to determine whether prior injury is associated with marijuana use; and 4) to determine whether marijuana-using problem drinkers want to change behaviors.The authors conducted a post-hoc analysis on data obtained prospectively. Subjects had injury and problem drinking: either measurable alcohol level (blood alcohol concentration, BAC), report of drinking, or an Alcohol Use Disorders Identification Test (AUDIT) score ofor =8. The study was conducted on weekend nights; 3,776 injured ED patients were screened, 383 refused, 578 were enrolled, and 433 had complete data.Of the 433 subjects, 48.3% reported using marijuana in the three months prior. Marijuana-using problem drinkers had more hazardous drinking, higher AUDIT scores (14.0 vs. 11.4, p0.001), and higher risk-taking scores (12.4 vs. 10.1, p0.001). More used other drugs (69.7% vs. 30.3%, p0.001). In regression analyses, marijuana use remained an independent predictor of prior injury (OR = 2.16, 95% CI = 1.25 to 3.75), particularly prior alcohol-related (OR = 2.26, 95% CI = 1.45 to 3.53) and motor-vehicle-related (OR = 1.69, 95% CI = 1.03 to 2.79) injury. Readiness-to-change scores were similar (4.14 vs. 4.22, p = 0.21) between users and nonusers.Marijuana use among injured problem drinkers is prevalent. Their risk of prior injury is increased. Counseling for alcohol and injury should address marijuana use.

Therapeutic and diagnostic advances have continued to reduce mortality and morbidity from acute coronary syndrome. Thrombolytic therapy and numerous other medical and invasive options are now widely available for treatment of acute myocardial infarction (MI). Bedside enzymatic assays and cardiac imaging modalities are more available for rapid diagnosis.

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.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.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).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.

Characteristics associated with intention to change drinking were examined in 254 adolescents treated in an emergency department for alcohol. Younger age, living at home, lower baseline level of drinking and drinking problems, greater depression, having penalties for breaking family drinking rules, higher injury severity, being frightened, and being admitted to the hospital predicted greater intention to change drinking at the time of the event. Baseline characteristics related to being in the action stage of change 3 months later were younger age; lower drinking; having penalties for breaking family drinking rules; injury severity; and number of anticipated consequences, including being in trouble with parents. This study has implications for brief interventions that capitalize on potential teachable moments with problem-drinking adolescents.

Approximately 6 million U.S. patients present to emergency departments annually with symptoms suggesting acute cardiac ischemia. Triage decisions for these patients are important but remain difficult.To test whether computerized prediction of the probability of acute ischemia, used with electrocardiography, improves the accuracy of triage decisions.Controlled clinical trial.10 hospital emergency departments in the midwestern, southeastern, and northeastern United States.10689 patients with chest pain or other symptoms suggestive of acute cardiac ischemia.The probability of acute ischemia predicted by the acute cardiac ischemia time-insensitive predictive instrument (ACI-TIPI), either automatically printed or not printed on patients' electrocardiograms.Emergency department triage to a coronary care unit (CCU), telemetry unit, ward, or home. Other measurements were the bed capacity of the CCU relative to that of the telemetry unit; training or supervision status of the triaging physician; and patient diagnoses and outcomes based on clinical, electrocardiographic, and creatine kinase data.For patients without cardiac ischemia, in hospitals with high-capacity CCUs and relatively low-capacity cardiac telemetry units, use of ACI-TIPI was associated with a reduction in CCU admissions from 15% to 12%, a change of -16% (95% CI, -30% to 0%), and an increase in emergency department discharges to home from 49% to 52%, a change of 6% (CI, 0% to 14%; overall P=0.09). Across all hospitals, for patients evaluated by unsupervised residents, use of ACI-TIPI was associated with a reduction in CCU admissions from 14% to 10%, a change of -32% (CI, -55% to 3%); a reduction in telemetry unit admissions from 39% to 31%, a change of -20% (CI, -34% to -2%); and an increase in discharges to home from 45% to 56%, a change of 25% (CI, 8% to 45%; overall P=0.008). Among patients with stable angina, in hospitals with high-capacity CCUs, use of ACI-TIPI was associated with a reduction in CCU admissions from 26% to 13%, a change of -50% (CI, -70% to -17%), and an increase in discharges to home from 20% to 22%, a change of 10% (CI, -29% to 71%; overall P=0.02). At hospitals with high-capacity telemetry units, use of ACI-TIPI was associated with a reduction in telemetry unit admissions from 68% to 59%, a change of -14% (CI, -27% to 1%), and an increase in emergency department discharges to home from 10% to 21%, a change of 100% (CI, 22% to 230%; overall P=0.02). Among patients with acute myocardial infarction or unstable angina, use of ACI-TIPI did not change appropriate admission (96%) to the CCU or telemetry unit at hospitals with high-capacity CCUs or telemetry units.Use of ACI-TIPI was associated with reduced hospitalization among emergency department patients without acute cardiac ischemia. This result varied as expected according to the CCU and cardiac telemetry unit capacities and physician supervision at individual hospitals. Appropriate admission for unstable angina or acute infarction was not affected. If ACI-TIPI is used widely in the United States, its potential incremental impact may be more than 200000 fewer unnecessary hospitalizations and more than 100000 fewer unnecessary CCU admissions.

Objective: To determine the association of ethanol intoxication with hypoglycemia in ED patients. Methods: Retrospective, laboratory log review of 953 consecutive patients who were evaluated for ethanol intoxication in an urban university hospital ED over a three-month period. Simultaneous serum glucose determination was carried out for each patient and associations between ethanol level and glucose were sought. Results: Glucose concentrations were unavailable for 16 patients (1.7%). Of the remaining patients, 584 patients had detectable ethanol concentrations (ethanol-positive), and 353 had no detectable ethanol (ethanol-negative). Ethanol concentrations (mean ± SD) in the ethanol-positive group were 50.11 ± 24.08 mmol/L (231 ± 111 mg/dL), and glucose concentrations were 5.83 ± 1.94 mmol/L (105 ± 35 mg/dL). Hypoglycemia [glucose

Discharging patients with acute myocardial infarction or unstable angina from the emergency department because of missed diagnoses can have dire consequences. We studied the incidence of, factors related to, and clinical outcomes of failure to hospitalize patients with acute cardiac ischemia.We analyzed clinical data from a multicenter, prospective clinical trial of all patients with chest pain or other symptoms suggesting acute cardiac ischemia who presented to the emergency departments of 10 U.S. hospitals.Of 10,689 patients, 17 percent ultimately met the criteria for acute cardiac ischemia (8 percent had acute myocardial infarction and 9 percent had unstable angina), 6 percent had stable angina, 21 percent had other cardiac problems, and 55 percent had noncardiac problems. Among the 889 patients with acute myocardial infarction, 19 (2.1 percent) were mistakenly discharged from the emergency department (95 percent confidence interval, 1.1 to 3.1 percent); among the 966 patients with unstable angina, 22 (2.3 percent) were mistakenly discharged (95 percent confidence interval, 1.3 to 3.2 percent). Multivariable analysis showed that patients who presented to the emergency department with acute cardiac ischemia were more likely not to be hospitalized if they were women less than 55 years old (odds ratio for discharge, 6.7; 95 percent confidence interval, 1.4 to 32.5), were nonwhite (odds ratio, 2.2; 1.1 to 4.3), reported shortness of breath as their chief symptom (odds ratio, 2.7; 1.1 to 6.5), or had a normal or nondiagnostic electrocardiogram (odds ratio, 3.3; 1.7 to 6.3). Patients with acute infarction were more likely not to be hospitalized if they were nonwhite (odds ratio for discharge, 4.5; 95 percent confidence interval, 1.8 to 11.8) or had a normal or nondiagnostic electrocardiogram (odds ratio, 7.7; 95 percent confidence interval, 2.9 to 20.2). For the patients with acute infarction, the risk-adjusted mortality ratio for those who were not hospitalized, as compared with those who were, was 1.9 (95 percent confidence interval, 0.7 to 5.2), and for the patients with unstable angina, it was 1.7 (95 percent confidence interval, 0.2 to 17.0).The percentage of patients who present to the emergency department with acute myocardial infarction or unstable angina who are not hospitalized is low, but the discharge of such patients is associated with increased mortality. Failure to hospitalize is related to race, sex, and the absence of typical features of cardiac ischemia. Continued efforts to reduce the number of missed diagnoses are warranted.

Background: Brief intervention (BI) to reduce hazardous drinking and negative consequences such as injury has been effective when given in the emergency department (ED). The effectiveness and effect of BI has varied between injured and uninjured ED patients. This study compares injured and uninjured ED patients who admit to alcohol and marijuana use to determine their need and their readiness for BI. Patients and Methods: Participants volunteered to enter a randomized controlled trial of BI to reduce hazardous alcohol and marijuana use. Adult ED patients who had had alcohol in the last month and smoked marijuana in the last year were recruited. Those patients who were admitted to hospital, were under police custody, or were seeking treatment for substance use or psychiatric disorder were excluded. Research assistants interviewed participants using a validated questionnaire. Data were analyzed using SAS (version 9.1). Binominal tests of proportions, t-test analyses, and transformations were conducted as appropriate. Results: Injured (n = 249) and uninjured (n = 266) study participants reported very high, statistically equivalent (P > 0.05), rates of binge drinking (4-5 days/month), marijuana use (13 days/month), driving under the influence of marijuana or alcohol (>49% in the last 3 months), injury (>83% in the last year), and other negative consequences (>64% in the last 3 months) prior to their ED visit. These behaviors and the consequences demonstrate a need for change. Both injured and uninjured subjects were ready to change (>56%) and confident they could change (>91%) alcohol and marijuana use. Discussion: ED patients who admit to alcohol and marijuana use also use other hazardous substances and participate in high-risk behaviors. In both injured and uninjured patients who admit using alcohol and marijuana, the ED visit is an opportunity to deliver BI to reduce alcohol and marijuana use and associated risk behaviors and the subsequent injury and negative consequences. Given their risk behaviors and experience of negative consequences, members of both injured and uninjured groups have an equal need for BI. Fortunately, in both groups, a high number of members express motivation to change.

Hispanics, particularly men of Mexican origin, are more likely to engage in heavy drinking and experience alcohol-related problems, but less likely to obtain treatment for alcohol problems than non-Hispanic men. Our previous research indicates that heavy-drinking Hispanics who received a brief motivational intervention (BMI) were significantly more likely than Hispanics receiving standard care to reduce subsequent alcohol use. Among Hispanics who drink heavily the BMI effectively reduced alcohol use but did not impact alcohol-related problems or treatment utilization. We hypothesized that an adapted BMI that integrates cultural values and addresses acculturative stress among Hispanics would be more effective. We describe here the protocol for the design and implementation of a randomized (approximately 300 patients per condition) controlled trial evaluating the comparative effectiveness of a culturally adapted (CA) BMI in contrast to a non-adapted BMI (NA-BMI) in a community hospital setting among men of Mexican origin. Study participants will include men who were hospitalized due to an alcohol related injury or screened positive for heavy drinking. By accounting for risk and protective factors of heavy drinking among Hispanics, we hypothesize that CA-BMI will significantly decrease alcohol use and alcohol problems, and increase help-seeking and treatment utilization. This is likely the first study to directly address alcohol related health disparities among non-treatment seeking men of Mexican origin by comparing the benefits of a CA-BMI to a NA-BMI. This study stands to not only inform interventions used in medical settings to reduce alcohol-related health disparities, but may also help reduce the public health burden of heavy alcohol use in the United States.
