Brief motivational interviewing in a hospital setting for adolescent smoking: a preliminary study.

This study tested the feasibility and efficacy of a brief smoking intervention for adolescents in a hospital setting. Forty adolescent patients were randomized to receive either brief advice or a motivational interview, a nonconfrontational therapeutic intervention. Feasibility of brief smoking interventions with teen patients was supported by high rates of recruitment, retention, and quit attempts, and long periods of continuous abstinence. Although between-groups differences on smoking measures were not significant at 3-month follow-up, an effect size of h = .28 was noted. The sample showed significant decreases in smoking dependence and number of days smoked. Baseline stage of change, smoking rate, and depression were significant prospective predictors of smoking outcome. Implications for smoking intervention research with adolescents are discussed.

Brief intervention for harm reduction with alcohol-positive older adolescents in a hospital emergency department.

This study evaluated the use of a brief motivational interview (MI) to reduce alcohol-related consequences and use among adolescents treated in an emergency room (ER) following an alcohol-related event. Patients aged 18 to 19 years (N = 94) were randomly assigned to receive either MI or standard care (SC). Assessment and intervention were conducted in the ER during or after the patient's treatment. Follow-up assessments showed that patients who received the MI had a significantly lower incidence of drinking and driving, traffic violations, alcohol-related injuries, and alcohol-related problems than patients who received SC. Both conditions showed reduced alcohol consumption. The harm-reduction focus of the MI was evident in that MI reduced negative outcomes related to drinking, beyond what was produced by the precipitating event plus SC alone.

Ethanol-associated hypoglycemia is uncommon.

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 < 3.72 mmol/L (67 mg/dL)] was observed for five (0.9%) ethanol-positive patients. It was classified as mild-moderate [2.78-3.66 mmol/L (50-66 mg/dL)] for four patients (0.7%) and severe [< 2.78 mmol/L (50 mg/dL)] for one (0.2%). Ethanol concentrations ranged from 25.60 to 68.33 mmol/L (118 to 315 mg/dL). There was no correlation between ethanol and glucose concentrations in any subset of the ethanol-positive patients population. In the ethanol-positive group, patients who had several ethanol-positive visits (56 patients, mean 3.6 visits/patient) accounted for four of the five episodes of hypoglycemia, including the one episode of severe hypoglycemia. The frequency of hypoglycemia in repeat visitors (2.0%) was higher than that in the group of patients without repeat visits (0.2%). In the ethanol-negative group, there were four (1.1%) episodes of mild-moderate hypoglycemia and no severely hypoglycemic patients. Hypoglycemia was not more likely to occur among ethanol-positive patients than it was among ethanol-negative patients. CONCLUSION: Hypoglycemia was uncommonly associated with ethanol intoxication, and was found almost exclusively among patients with several ethanol-positive visits. Glucose and ethanol concentrations do not show any linear correlation; patients with higher ethanol concentrations are not at higher risk of hypoglycemia. Hypoglycemia is not more likely to occur in ethanol-positive than in ethanol-negative patients. Initial glucose screening does not appear to be necessary for all patients suspected of intoxication; selective screening may be more appropriate.

Analysis of alcohol use clusters among subcritically injured emergency department patients.

OBJECTIVES: 1) To cluster patients according to self-reported drinking patterns using cluster analysis; 2) to externally validate clustered groups on variables related to drinking but not used in the cluster analysis; and 3) to use the clustered patients' responses to alcohol consumption questions to develop a brief screening tool emergency physicians can use to identify patients in need of referral or intervention related to potentially hazardous alcohol consumption. METHODS: A self-report battery was administered to 95 subcritically injured patients. Patients also were saliva alcohol-tested upon arrival to the ED. Using the patients' self-reported quantity, frequency of alcohol consumption, and frequency of having > or = 6 drinks on a drinking occasion, patients were categorized into 3 groups using cluster analysis. The 3 clusters were externally validated using injury-related variables, alcohol-related consequences, and the patients' reported readiness to change drinking. A screening tool was developed using cutoff values reported by the patients' answers to drinking pattern questions. RESULTS: Fifty-nine patients were alcohol-negative, and 36 tested alcohol-positive (i.e., > 4 mmol/L [> 20 mg/dL]) or had elevated scores on an alcohol problem screening instrument. Three distinct drinking pattern clusters were found. Clusters were validated using discriminant function analysis and multivariate analyses of variance to confirm cluster classifications. Steady and high-intensity drinkers reported more alcohol-related negative consequences, and high-intensity drinkers indicated they would consider changing their drinking. The screening tool correctly classified 97% of the patient sample into their respective clusters. CONCLUSIONS: Using the drinking pattern questions in the clustering procedure was effective for grouping injured patients into clusters that could be differentiated on other drinking-related variables. The resulting screening tool can be used in the ED setting to screen patients for further assessment and intervention. The readiness-to-change results support the assertion that the injury event provides a "teachable moment" for subcritically injured patients whose injury may be related to their alcohol consumption.

Alcohol use among subcritically injured emergency department patients.

OBJECTIVES: To determine the incidence of alcohol use in subcritically injured patients presenting to the ED, by using a saliva alcohol test (SAT) at ED triage during the ED initial assessment; to compare the incidence of alcohol use revealed by the SAT with documentation of alcohol use by ED nurses and emergency physicians (EPs) blinded to the SAT results; and to describe the demographics of the SAT-positive, subcritically injured population. METHODS: A blinded, prospective, observational evaluation of ED patients presenting with subcritical injuries was performed. The patients were tested for alcohol use with an SAT, and a subsequent record review was conducted for extraction of demographic data and evidence of documentation of alcohol use by ED nurses and EPs blinded to the SAT results. RESULTS: During the study, 791 subcritically injured patients had SATs performed. Twenty-one percent of these patients were found to be alcohol-positive by SAT. Either the ED nurse or the EP documented a clinical impression of alcohol use for 52% of the SAT-positive patients. There were higher SAT-positive rates among men (24%), victims of assault (47%), and patients arriving at night (41%). CONCLUSIONS: While the SAT identified 21% of the subcritically injured patient population as alcohol-positive, ED nurse and EP documentation did not identify half of these alcohol-positive patients. Many of these patients may be at risk for additional injuries related to their drinking behavior.

Injury as a motivator to reduce drinking.

OBJECTIVES: To identify predictors of readiness to change drinking behavior by minor-injury patients who had positive saliva alcohol tests (SATs) in the ED. To develop and test a model intended to be prognostic of readiness to change, which included predispositional and injury-event-related variables. METHODS: An on-site survey was conducted of minor-injury ED patients sampled consecutively during predesignated periods. Patients were identified as SAT-positive during their screening evaluations. After giving their consent, they were administered a self-report battery that assessed predispositional and injury-event-related variables as well as readiness to change their drinking. Predictors of readiness to change drinking were tested with regression analyses. RESULTS: Twenty-four SAT-positive patients participated; there were 18 men and six women (average age 34 years). Preinjury predispositional variables were by themselves unrelated to the patient's readiness to change while in the ED. Aversiveness of the injury and perception of degree of alcohol involvement were injury-event-related variables predictive of readiness to change (p < 0.008). Negative consequences attributed to drinking prior to the injury event strengthened the association of injury aversiveness and alcohol involvement with readiness to change (p < 0.0075). CONCLUSION: Interventions to decrease drinking in this population should focus on increasing patient awareness of the association between drinking, injuries, and other alcohol-related negative consequences.

Identification of hazardous/harmful drinking among subcritically injured patients.

OBJECTIVES: To examine the relationship between a saliva alcohol test (SAT) and hazardous/harmful drinking, as measured by the Alcohol Use Disorders Identification Test (AUDIT), among a sample of subcritically injured patients. METHODS: Patients (n = 78) seeking treatment for a subcritical injury were saliva-tested for alcohol and interviewed regarding their drinking behaviors and related difficulties. Associations of SAT values with AUDIT results were determined. RESULTS: SAT results and hazardous/harmful drinking were not independent events (p < 0.001). Estimates of sensitivity and specificity (using a dichotomous SAT result [> or = 4 mmol/L] to identify positive AUDIT patients) were 65.2% and 83.6%, respectively. SAT-positive people had significantly higher AUDIT scores than did SAT-negative individuals (p < 0.0001). Patients experiencing assault-type injuries were much more likely to be SAT-positive than were patients incurring other types of injury. Discriminant function analysis suggests that AUDIT scores can successfully identify SAT-positive and SAT-negative patients; the analysis accounted for 42.5% of the variance and correctly classified 84.6% of the sample. CONCLUSIONS: The use of an easy-to-administer, noninvasive, routine SAT, among patients presenting for a subcritical injury in a hospital ED, provides a mechanism for the identification of individuals with a history of hazardous/harmful drinking. However, since discrimination of hazardous/harmful drinking is imperfect, some caution is warranted when conducting such screening activities.

"Inappropriate" emergency department use: a comparison of three methodologies for identification.

OBJECTIVE: To determine the level of agreement between the rates of "inappropriate" ED visits assigned to a cohort of ambulatory patients based on three methods of defining ED use appropriateness. METHODS: Ambulatory adult patients seen at one urban, university-based teaching hospital ED between 8 AM and midnight during select days from April to June 1994 were assessed regarding the appropriateness of their ED visits. Patients triaged to acute resuscitation rooms in the ED were excluded. Eligible patients were asked to complete a 90-question survey including demographics and health service use (response rate 81%). The appropriateness of ED use was assessed for consenting respondents by 1) application of a list of 51 non-emergent complaints that have been used by managed care providers and previously published (TRIAGE), 2) use of ten explicit criteria (e.g., need for parenteral medication) from prior publications (EXPLICIT), and 3) the consensus of two emergency physicians (EPs) reviewing the records of ED patients (PHYS). All three methods were applied at the time of retrospective chart review. The agreement between methods was evaluated using kappa scores. RESULTS: Of the 892 eligible respondents, 64% were white, 54% were employed, 50% were female, and 29% were uninsured. Of the respondents, 26% had no regular source of ambulatory care and 25% considered the ED their regular source of care. The assigned rates of "inappropriate" visits using the three definitions were TRIAGE, 58%; PHYS, 47%; and EXPLICIT, 42%. Of those deemed "inappropriate" by the EXPLICIT criteria, 81% also were judged as "inappropriate" by the TRIAGE criteria, and 72%, by the PHYS criteria. Of those patients deemed "inappropriate" by the TRIAGE criteria, 59% also were judged as "inappropriate" by the EXPLICIT criteria, and 66%, by the PHYS criteria. Levels of agreement (kappas) were TRIAGE/EXPLICIT, 0.39; TRIAGE/PHYS, 0.42; and EXPLICIT/PHYS, 0.42. CONCLUSION: There is only moderate agreement between different methods of determining appropriateness of ED use. Until further refinement is made in triage assessment, managed care organizations and EPs should remain cautious when implementing a protocol that defines and restricts "inappropriate" ED visits.

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.

Patients with alcohol problems in the emergency department, part 2: intervention and referral. SAEM Substance Abuse Task Force. Society for Academic Emergency Medicine.

Early intervention and appropriate referral of patients with alcohol problems have the potential to reduce alcohol-related morbidity and mortality. Part 1 of this series introduced screening tools that can be applied in the ED to allow early detection of at-risk drinkers. This article was developed by members of the SAEM Substance Abuse Task Force and describes assessment and intervention techniques once the at-risk or dependent drinkers has been identified. Appropriate aftercare and referral of patients found to have alcohol problems are also discussed.

Patients with alcohol problems in the emergency department, part 1: improving detection. SAEM Substance Abuse Task Force. Society for Academic Emergency Medicine.

Medical and social problems related to alcohol use are frequently seen in the ED. Often, the tempo of emergency medicine practice seems to preclude assessment beyond that required by the acute complaint. However, detection of ED patients with alcohol problems can occur using brief screening tools. This article was developed by members of the SAEM Substance Abuse Task Force, and describes screening tools that have been used successfully to identify at-risk and dependent drinkers. Their brevity, reproducibility, and accuracy vary somewhat, but screening can be realistically performed in the busy ED setting. The early detection of patients with alcohol problems would provide the opportunity for early intervention, and may reduce subsequent morbidity and mortality in this patient population.

Alcohol expectancies as a mediator of the relationship between injury and readiness to change drinking behavior.

There is a well-established relationship between alcohol expectancies and drinking behavior. The purpose of the present study was to extend the literature by examining the role of alcohol expectancies in determining readiness to change drinking behavior among injured emergency department patients who screened positive for hazardous drinking. Negative expectancies were found to partially mediate the relationships of alcohol-related injuries and injury aversiveness to readiness to change drinking behavior. Results suggest that negative alcohol expectancies are a potential means of increasing patients' readiness to change drinking behavior.

Evaluating the effects of a brief motivational intervention for injured drinkers in the emergency department.

OBJECTIVE: The study aim was to test whether a brief motivational intervention, with or without a booster session, would improve drinking-related outcomes more than standard Emergency Department (ED) treatment. METHOD: The study population consisted of 539 (78% male) injured patients treated in the ED and discharged to the community following their treatment. Injured patients met inclusion criteria if they were assessed as hazardous or harmful drinkers by scoring eight or more on the AUDIT and/or having alcohol in their system at the time of their injury or ED visit. Patients were randomly assigned to either standard care (SC), brief intervention (BI) or brief intervention plus a booster session (BIB). At 1-year follow-up, 447 patients (83% of the sample) were re-interviewed to measure alcohol-related negative consequences, injuries and drinking. RESULTS: Patients receiving BIB, but not B1 patients, reduced alcohol-related negative consequences and alcohol-related injuries more than did those in the SC group. All three groups reduced their days of heavy drinking. Patients with histories of hazardous drinking responded to BIB, whether or not they had consumed alcohol prior to their injury. CONCLUSIONS: Together, these results indicate that the effects of a booster session that is added to a brief intervention in the ED can be helpful to injured patients with a history of hazardous or harmful drinking, irrespective of whether they have consumed alcohol prior to their injury.

The significance of changing needles when inoculating blood cultures: a meta-analysis.

Several recent studies have concluded that the changing of needles prior to inoculation of blood culture bottles does not reduce the contamination rate, although there is a consistent trend toward a reduction in number of contaminated cultures when the needle is changed prior to inoculation. We performed a meta-analysis of available studies prospectively comparing blood culture contamination rates with and without a needle change prior to inoculation. The overall weighted contamination rate when the needle was changed prior to inoculation was 2.0%, compared to 3.7% when the needle was not changed. Since an increase of approximately $5,000 in costs per patient is associated with a contaminated blood culture, this reduction in contamination rate could save approximately $85,000 for every 1,000 cultures performed. Our meta-analysis demonstrates reduced blood culture contamination when the needle used for phlebotomy is changed prior to inoculation. This should be considered when setting clinical policy regarding the performance of blood cultures.

Sports-related pneumothorax.

Pneumothorax and pneumomediastinum are rare complications of athletic activity. Spontaneous pneumothorax has been reported in association with several sports, but reports of pneumothorax associated with blunt trauma sustained during sporting activity are rare. We present a case series of patients in whom pneumothorax or pneumomediastinum developed as a result of blunt trauma sustained during participation in a contact sport.

Alcohol-related expectancies and assaults among injured drinkers in the emergency department setting.

This study examined the extent to which alcohol-related expectancies were associated with assaults among 278 injured drinkers in the emergency department setting. Results of logistic regression analyses indicated that patients who were male, had high blood alcohol levels and who expected alcohol to make them more careless were more likely to report being assaulted. Conversely, among males, patients who expected to become more powerful and aggressive when drinking were less likely to be assaulted. These findings suggest that helping patients understand how expectancies surrounding alcohol use shape drinking and its behavioral concomitants may circumvent their risk for future assaults.

Use of the ED as a regular source of care: associated factors beyond lack of health insurance.

STUDY OBJECTIVE: To determine the characteristics and health care experiences of patients who identify the ED as their usual source of care. METHODS: We conducted a cross-sectional survey in a Level I trauma center ED at an urban teaching hospital. Our population comprised 892 adults who presented to the ED over the course of 30 days. We asked participants about their regular source of health care, previous health care experiences, and perceptions of the use of the ED. RESULTS: Patients who reported the ED as their regular source of care were three times more likely to have used the ED more than once in the preceding year. Among the regular ED users, 68% desired a physician as their regular source of care, and 46% of these subjects said they had tried unsuccessfully to get one in the preceding year. Five variables were associated with self-report of the ED as the regular source of health care: annual income less than $30,000, having been refused care in an office or clinic in the past, perception that an ED visit costs less than an office visit, absence of chronic illness, and unwillingness to use the ED if a $25 copayment were in effect. CONCLUSION: Low income, perceived mistreatment by health care providers, and misperception about charges contribute to use of the ED as a regular site for health care. These factors suggest the difficulty of altering health care use patterns in this group.
