Screening trauma patients for alcoholism according to NIAAA guidelines with alcohol use disorders identification test questions.

Drinking pattern criteria (drinking frequency and number of drinks per occasion) issued by the National Institute on Alcohol and Abuse and Alcoholism (NIAAA) to screen primary practice patients for alcohol problems were evaluated in 1216 injured patients treated in a regional trauma center. Vehicular crash victims predominated (50.2%, of whom 64.5% were drivers), followed by victims of violence (31.2%) and nonviolent-injury victims (18.5%). Alcohol Use Disorders Identification Test (AUDIT) questions #1 (drinking frequency) and #2 (drinks/day) were used to assess the patients for current alcohol dependence (CAD). AUDIT responses roughly approximating NIAAA guidelines (high threshold: drinks > or = 4 times/week, > or = 5 drinks/day) and those indicating less drinking (low threshold: drinks > or = 2-3 times/ week, > or = 3 drinks/day) were chosen. Comparisons were made relative to sensitivity and specificity of responses in detecting CAD. When low threshold responses were used for either question, sensitivity to detect CAD increased overall (#1 from 0.53 to 0.80, #2 from 0.62 to 0.88) as well as among the subgroups of patients, whereas specificity remained high or at acceptable levels overall (#1 from 0.95 to 0.82, #2 from 0.92 to 0.71) and among the subgroups of patients. Study findings suggest that, among injured drivers and other groups of trauma center patients, lesser amounts of drinking should be used as screening criteria for CAD than are used for the general population.

Psychoactive substance use disorders among seriously injured trauma center patients.

OBJECTIVE: To assess the prevalence of psychoactive substance use disorders (PSUDs) among a large, unselected group of seriously injured trauma center patients, using a standardized diagnostic interview and criteria. DESIGN: Prevalence study. SETTING: A level I regional trauma center. PATIENTS: Trauma center patients fulfilling the following criteria were eligible subjects: aged 18 years or older, admission from injury scene, length of stay of 2 days or longer, and intact cognition. OUTCOME MEASURES: The PSUDs were diagnosed using the Structured Clinical Interview (SCID) for the Diagnostic and Statistical Manual of Mental Disorders, Revised Third Edition (DSM-III-R) and were categorized as abuse or dependence and past or current (within past 6 months). The SCID results were analyzed with respect to demographic factors, injury type, and blood alcohol concentration and urine toxicology results, using chi2 and logistic regression techniques. RESULTS: Of the 1220 patients approached for study, 1118 (91.6%) consented. More than half (54.2%) had a diagnosis of a PSUD in their lifetime. Approximately 90% of alcohol and other drug use diagnoses were for dependence and more than 62% were current. Overall, 24.1% of patients were currently alcohol dependent (men, 27.7%; women, 14.7%; P<.001), and 17.7% were currently dependent on other drugs (men, 20.2%; women, 11.2%; P<.001). Current alcohol dependence rates were not associated with race; rates of dependence on other drugs were higher among nonwhites and victims classified with intentional injuries. While 54.3% of blood alcohol-positive patients were currently alcohol dependent and 38.7% of patients with positive urine screening test results for drugs other than alcohol and nicotine were currently drug dependent, 11.7% of blood alcohol-negative and 3.9% of drug-negative patients, respectively, had current diagnoses of dependence on psychoactive substances. CONCLUSIONS: A high percentage of seriously injured trauma center patients are at risk of having current PSUDs. Patients with positive toxicology screening test results and/or positive screening questionnaire responses should be referred for formal evaluation and treatment.

Alcoholism at the time of injury among trauma center patients: vehicular crash victims compared with other patients.

A structured in-depth interview employing standardized criteria was used to determine the prevalence of lifetime and current alcohol dependence (alcoholism) in unselected consecutive patients admitted to a regional Level I trauma center. Of 629 patients, 157 (25.0%) were current alcoholics at the time of injury. An additional 87 (13.8%) were diagnosed as lifetime non-current alcoholics. There was no significant difference in the rates of current alcohol dependence among patients injured in vehicular crashes (23.5%), other unintentional trauma victims (29.3%), and those injured as a result of violence (24.6%). Of BAC+ (blood alcohol concentration positive) patients, 54.5% were current alcoholics. However, 14.4% of alcohol-negative patients were also diagnosed as alcohol dependent.

The accuracy of the CAGE, the Brief Michigan Alcoholism Screening Test, and the Alcohol Use Disorders Identification Test in screening trauma center patients for alcoholism.

OBJECTIVE: To evaluate the accuracy of questionnaire screening instruments to identify lifetime alcohol dependence among trauma center patients. METHODS: The study was conducted at a Level I trauma center between September 1994 and November 1996. Patients meeting eligibility requirements (> or = 18 years old, admission from injury scene, > or = 2 days of hospitalization, intact cognition) were evaluated for alcohol abuse and dependence. Screening instruments consisted of the CAGE, the Brief Michigan Alcoholism Screening Test, and the Alcohol Use Disorders Identification Test. Screening results were compared with lifetime alcohol dependence diagnoses made using the in-depth Psychoactive Substance Use Disorders section of the Structured Clinical Interview. Accuracy was quantified as sensitivity, specificity, positive/negative predictive values, and receiver operating characteristic curves (used to calculate area under the curve). RESULTS: Of the 1,118 patients studied, lifetime alcohol dependence was diagnosed by Structured Clinical Interview in 397 (35.5%), and abuse was diagnosed in 90 (8.1%) others. The CAGE was the best predictor of lifetime alcohol dependence, i.e., had the largest area under the curve (93%) and the highest sensitivity (84%), specificity (90%), positive predictive value (82%), and negative predictive value (91%). Among patients testing positive for alcohol, 63% had a lifetime alcohol dependence diagnosis. CONCLUSION: The CAGE is an efficient screening test to detect alcohol dependence in trauma center populations. It should be used in combination with alcohol testing to identify patients at risk of alcohol use problems.

A substance abuse consultation service. Enhancing the care of hospitalized substance abusers and providing training in addiction psychiatry.

The authors review the literature on the high prevalence but underrecognition of substance abuse among hospitalized patients and the general unavailability of hospital-based substance abuse consultation services. They describe the development, clinical operations, staffing, and teaching activities of a large substance abuse consultation service in one urban academic medical center and detail the service's growth and changing utilization patterns over an 8-year period, reporting the clinical characteristics of 1,819 patients seen over a 1-year period. Differences in patient demographics, patterns of substance use, and diagnoses were highly significant from one referring service to another. The authors discuss the implications of such a service for patient care and teaching.

New developments in employee assistance programs.

Employee assistance programs have developed from alcoholism assessment and referral centers to specialized behavioral health programs. Comprehensive employee assistance programs are defined by six major components: identification of problems based on job performance, consultation with supervisors, constructive confrontation, evaluation and referral, liaison with treatment providers, and substance abuse expertise. Other services have been added as enhancements to the basic model and include managed behavioral health activities and professional assistance committees, which provide services for impaired professionals and executives. Recent developments in the field are illustrated through examples from the experience of the employee assistance program at the University of Maryland Medical System in Baltimore.

Four years experience of a hospital's impaired physician committee.

Physician impairment contributes to patient morbidity, malpractice claims, physician license loss and suicide. This paper describes four years of experience of the University of Maryland's Professional Assistance Committee. The committee is composed of medical staff members. Its mission is to help impaired physicians obtain assessment, treatment and monitoring, and to protect patients from harm. The committee has evaluated 23 cases over the past four years. Ten were credential checks, and 13 investigations of active problems. Eight of the 23 cases were for alcohol, eight for drug, and seven for behavioral problems. Only one person lost medical staff privileges. The committee has been well accepted by the medical staff and hospital administration and can be easily reproduced in other hospitals.

Addictions training for physicians and other licensed health care professionals in Maryland.

Physicians and other health care providers have multiple opportunities in the course of a typical practice year to identify and treat individuals who abuse alcohol and other drugs. Although substance abuse is very common in clinical practice, providers routinely fail to intervene in a timely fashion due to negative attitudes, incomplete knowledge, and poorly developed practice skills. Over the past ten years, addictions training of licensed health care providers nationally and in Maryland has improved significantly. This article describes recent national training trends and current educational programs statewide for medical students, physicians in residency and fellowship programs, and licensed providers in dentistry, nursing, pharmacy, psychology, and social work. Several strategies for improving professional training in addictions in the future are discussed and the importance of shifting to an interprofessional training model is emphasized.

Psychiatric consultation with substance abusers in early recovery.

The frequent co-occurrence of mental and substance use disorders ("dual diagnosis") has created a role for addiction-trained psychiatric consultants in drug and alcohol treatment programs. The complex treatment needs of the dually diagnosed required that the consultant psychiatrist have knowledge about the existing treatment models of chemical dependency, the recovery process, and the complex relationship between substance abuse and psychopathology. This paper reviews the existing clinical models for understanding and treating chemical dependency and then proposes an approach to consultation practice that employs a developmentally-based clinical model. The consultation work of three academic addiction psychiatrists who utilize a developmental approach is described. The demographic and diagnostic characteristics of their consultation cases from three substance abuse inpatient rehabilitation programs for a 1-year period are summarized. Five major tasks for addiction psychiatry consultants are identified and discussed: diagnostic evaluation, identification of recovery barriers, identification of relapse triggers, recovery-oriented brief psychotherapy, and pharmacotherapy.

Psychoactive substance dependence among trauma center patients.

INTRODUCTION: The practice of assessing only trauma patients with elevated blood alcohol concentrations (BACs) or positive drug screens for psychoactive substance use disorders (PSUDs) was evaluated. METHODS: Twenty-four BAC-negative (BAC-) (BAC, 0) and 21 BAC-positive (BAC+) (BAC, greater than or equal to 22 mmol/L or 100 mg/dL; mean, 41 mmol/L; range, 24.3 to 79 mmol/L) adult trauma patients were evaluated for alcoholism and other PSUDs using the Structured Clinical Interview (SCI) from the Diagnostic and Statistical Manual of Mental Disorders, Revised Third Edition (DSM-III-R). Approximately half were vehicular crash victims and 78% were men. RESULTS: A total of 64 PSUDs were diagnosed in 31 (68.9%) of the 45 patients; all but one was for dependence (vs abuse). Of the BAC+ patients, 14 (66.7%) met DSM-III-R criteria for alcohol dependence, 11 (78.6%) of whom also had other PSUDs not related to alcohol. Two other BAC+ patients had nonalcohol PSUDs. Of the BAC- patients, 11 (45.8%) had alcohol dependence, six (54.5%) of whom also had nonalcohol PSUDs. Another four BAC- patients had nonalcohol PSUDs. Overall, 76.2% of the BAC+ patients and 62.5% of the BAC- patients had a diagnosis of psychoactive substance dependence. CONCLUSION: All patients admitted to trauma centers should be assessed for alcoholism and other PSUDs.

Classification and characteristics of Army stress casualties during Operation Desert Storm.

During the Persian Gulf War, the U.S. Army provided mental health care to soldiers using a model that emphasized the identification and management of factors associated with combat stress. Nonpathological labels, such as combat stress reaction, a non-hospital-based care delivery system, and simple interventions were used to promote return to duty. The authors describe such services provided to the U.S. Army 7th Corps. A total of 158 patients were treated; 72 percent were men. Seventy percent were from the junior ranks. Thirteen soldiers were treated for axis I disorders, four for axis II disorders, and 118 for stress reactions. Ninety-nine percent of the soldiers treated were returned to effective duty after a brief intervention.

Social issues in the management of released hostages.

Mental health clinicians have assumed a more important role in the release of individuals held hostage by international terrorists. The author uses his experiences during three hostage releases in the late 1980s--the Achille Lauro incident, the hijacking of Pan Am Flight 73 in Karachi, Pakistan, and the release of a single hostage from Beirut--to illustrate important factors in managing victims. He describes an intervention model that emphasizes the importance of creating a healing social environment immediately after release. Such an environment encourages strong cohesiveness within the victim group, isolates the victims from external groups, promotes abreaction, and provides an opportunity for rest and replenishment. Interventions are made to restore a sense of power to the victims and to reduce their feelings of isolation and helplessness and of being dominated by the terrorists.

Outpatient benzodiazepine detoxification procedure for methadone patients.

Benzodiazepines are used by a substantial minority of opioid addicts on methadone maintenance. Alprazolam, now the most widely prescribed benzodiazepine in the United States, appears to have supplanted diazepam as the benzodiazepine drug of choice in this population. Its greater addiction liability, shorter half-life, and more intense withdrawal symptoms make addiction to alprazolam more likely and its management in methadone patients more complicated. This article describes a slow outpatient tapered reduction procedure that was utilized to detoxify benzodiazepine dependent methadone patients seen over a two-year period. The reduction procedure was offered to 22 opioid addicts on methadone maintenance who were regularly ingesting low to moderate amounts of benzodiazepines, primarily alprazolam. Of the 22 patients, 4 patients refused outpatient detoxification, and 18 were started on a reduction procedure. Twelve patients completed the detoxification procedure which averaged 7.8 weeks. Comparisons are made between completers and non-completers and essential design features of the procedure are discussed.

Engaging hospitalized heroin-dependent patients into substance abuse treatment.

The purpose of this study was to evaluate a 6-month outpatient program developed to improve abstinence and other health and social problems of heroin-addicted persons hospitalized in an urban academic medical center's medical or surgical unit and referred from the Substance Abuse Consult Service. Treatment intervention consisted of methadone therapy, daily group therapy, individual case management, medical and psychiatric consultation, and social services. The first 67 patients referred were followed for 6 months. Outcome measures were retention in treatment, urine drug screens, and health and social indicators. Patients averaged 19 weeks in treatment, with 52% of patients completing the 6-month program. Urine toxicology screens showed a reduction of illicit drug use. Patients improved deficits in health and social indicators by obtaining medical coverage, keeping outpatient medical appointments, and improving their housing conditions. Findings suggest that this combination of intensive psychosocial treatment with opioid substitution following an acute illness substantially impacts treatment outcomes. Implications for service delivery and health-care economics are discussed.

Benzodiazepine dependence and withdrawal: identification and medical management.

BACKGROUND: Primary care physicians prescribe benzodiazepines for the treatment of anxiety. Although most patients use the benzodiazepines appropriately, some patients experience benzodiazepine abuse, addiction, or physical dependence, each one of which is a distinct syndrome. Benzodiazepine dependence, which relates to the development of tolerance and an abstinence syndrome, can be produced by three disparate benzodiazepine use patterns. These distinct benzodiazepine use patterns can in turn create distinct withdrawal syndromes. High-dose benzodiazepine use between 1 and 6 months can produce an acute sedative-hypnotic withdrawal syndrome. In contrast, low-dose therapeutic range benzodiazepine use longer than 6 months can produce a prolonged, subacute low-dose benzodiazepine withdrawal syndrome. Daily, high-dose benzodiazepine use for more than 6 months can cause a combination of an acute high-dose benzodiazepine withdrawal and a prolonged, subacute low-dose withdrawal syndrome. In addition, patients may experience syndrome reemergence. METHODS: A literature search was conducted using the medical subject headings benzodiazepines, substance abuse, substance dependence, substance withdrawal syndrome, and benzodiazepines adverse effects. The years 1970 to the present were reviewed. RESULTS AND CONCLUSIONS: Medical management for acute benzodiazepine withdrawal includes the graded reduction of the current benzodiazepine dosage, substitution of a long-acting benzodiazepine, and phenobarbital substitution. However, the medical management of benzodiazepine dependence does not constitute treatment of benzodiazepine addiction. Primary care physicians can accept complete, moderate, or limited medical responsibility regarding patients with substance use disorders. However, all physicians should provide diagnostic and referral services.

Anxiety and substance use disorders: the treatment of high-risk patients.

Primary care physicians routinely treat patients with various anxiety disorders. These patients may have a substance use disorder or may be at high risk for abuse or addiction. Routine treatment of anxiety disorders with psychoactive drugs is successful in many patients, but it can lead to iatrogenic dependence in high-risk patients. This article describes addiction risk factors, drug pharmacodynamics, environment and environmental cues, and genetics. With these addiction risk factors in mind, the physician can apply a stepwise treatment protocol described in three progressive levels: conservative, nonpharmacological approaches; nonpsychoactive pharmacotherapy; and psychoactive pharmacotherapy. In addition, proper prescribing practices for high-risk patients are described in terms of diagnosis, dosage, duration, discontinuation, dependence, and documentation.
