Detection of alcohol problems in a hospital setting

Validity of the CAGE questionnaire in hospital

Objective

The CAGE questionnaire is considered a useful screening and case-finding tool for alcohol use disorders in clinical populations. Our objectives were to validate the French version of the CAGE against DSM-IV criteria and to assess performance of each item of the scale.

Method

Data were extracted from a hospital morbidity study conducted in central France. It concerned 5452 patients—48.5% men—in short and medium-stay units. Patients answered the CAGE questionnaire as a past-year assessment. The alcohol use disorders were diagnosed by the physicians using DSM-IV alcohol abuse or dependency criteria.

Results

The CAGE questionnaire for a cut-off of 2 had a sensitivity of 77% and a specificity of 94%. The CAGE test was more sensitive for patients diagnosed as alcohol-dependent than for alcohol abusers (61% vs. 84%) with the same specificity (94%). These values are close to those for the English-language CAGE. The first three items (CAG) were very similar, with sensitivity 70% and specificity 94%. The eye-opening question (E) differentiated sharply between abuse and dependency, with sensitivities of 18% and 46%, respectively. A questionnaire comprising only the CAG questions of the CAGE had properties similar to the full questionnaire.

Conclusion

CAGE is a good screening tool for alcohol abuse or alcohol dependency. Given the frequent—and insufficiently diagnosed—alcohol problems among inpatients, CAGE is indicated as a first-line tool for screening for the most severe alcohol use disorders in hospital. It should ideally be used systematically. A positive reply to any of the first three items should alert the clinician and prompt further investigation.

Detection of and intervention for excessive alcohol and tobacco use among adult hospital in-patients

Early detection and intervention for alcohol problems have been shown to reduce subsequent health consequences. However, the extent to which these practices have been implemented is unclear. The study assessed among hospital in-patients (1) the prevalence of at-risk drinking and smoking, (2) current practice in detection and intervention for at-risk drinking and smoking and (3) self-reported effect of any intervention. A brief self-administered questionnaire was administered to adult in-patients addressing alcohol use [Alcohol Use Disorders Identification Test (AUDIT) questionnaire], smoking and self-reported effect of any recent intervention for drinking or smoking. The participant's smoking status and alcohol use as recorded by medical and nursing staff was compared to self-reports. Of 448 in-patients, 50% (226) participated in the study; 38% (170) were ineligible and 12% (52) refused. Participants were aged 61.3 (+/-18.9) years. A higher number of problem drinkers (11.9% vs. 3.5%, p < 0.0001) and current smokers (17.3% vs. 9.3%, p < 0.0001) were identified by the questionnaire compared to the medical records. Hospital staff quantified smoking more consistently than alcohol (54% vs. 42%, p = 0.02). Of those who recalled an intervention, 19% of drinkers and 27% of smokers said they had stopped drinking or smoking for a period since that intervention. Further improvement is required in the rates of detection and interventions for alcohol use disorders and smoking in the hospital setting.

From data to evidence, to action: findings from a systematic review of hospital screening studies for high risk alcohol consumption

OBJECTIVE

To conduct a systematic review of hospital alcohol screening studies to identify effective and efficient evidence-based strategies.

METHOD

Sixty-five studies (N=100,980) of alcohol problem prevalence amongst hospital patients were reviewed.

RESULTS

Prevalence of positive alcohol screens varied according to hospital location, screening tool and patient characteristics. BAC measures (26%) were nearly twice as likely (OR=1.92, p<.001) to reveal positive screens in the ED than self-reports (16%). No difference was found in prevalence of self-report positive screens between ED (16%) and ward settings (17%). Males were two to four times more likely than females to screen positive (BAC: OR=2.37, p<.001, ED self-report: OR=3.07, p<.001, ward self-report: OR=4.30, p<.001). ED patients aged 20-40 years and ward patients aged 30-50 years had the highest prevalence of positive screens.

CONCLUSIONS

Prevalence of risky or problematic drinking among hospital patients is high and warrants systematic screening and intervention. Many hospitals lack sufficient resources to undertake widespread screening programs. For optimum return on resources, it is recommended to screen males in the ED using BAC measures. Established protocols applying priority criteria and staff training can increase screening accuracy and effectiveness.

Intérêt de l’utilisation systématique à l’hôpital d’un questionnaire de dépistage en alcoologie

OBJECTIVES

The CAGE questionnaire is considered a useful tool for detecting alcohol problems, especially in clinical populations. Its sensitivity exceeds 75% and its specificity 90%. Our objective was to assess performance of the French version of the CAGE (DETA) in identifying patients who meet the DSM-IV criteria and to discuss its usefulness in hospitals.

METHODS

Data come from study of hospital morbidity in the Auvergne district of central France in 1998. Alcohol problems were diagnosed by physicians using the DSM-IV alcohol abuse or dependency criteria. For each diagnostic category, we calculated the performance of the CAGE questionnaire at a cut-off of 2 (CAGE 2+) and of 1 (CAGE 1+).

RESULTS

The study included 5,452 patients--48.5% of them men--in acute- and intermediate-care facilities. CAGE 2+ had a sensitivity of 77% and a specificity of 94% among the diagnosed patients. It was more sensitive for patients diagnosed as alcohol-dependent than for alcohol abusers (61% vs 84%), but specificity was identical for both groups (94%). These results are similar to the properties of the English version. For a cut-off of 1 the CAGE had a sensitivity of 88% and a specificity of 87%.

CONCLUSION

The French version of CAGE is a useful screening tool for alcohol abuse and dependance. Its systematic use in hospitals is desirable: a positive response to any item should attract the physician's attention and lead to further investigation.

Mental disturbances and perceived complexity of nursing care in medical inpatients: results from a European study

AIMS AND OBJECTIVES

The relationship between mental disturbances - anxiety and depression, somatization and alcohol abuse - on admission to internal medicine units and perceived complexity of care as indicated by the nurse at discharge was studied. The goal was to study the utility of short screeners for mental disturbances to select patients for case-management on admission.

DESIGN

The study had a cohort design: patients were included on admission and followed through their hospital stay until discharge. The study was conducted within the framework of the European Biomed 1 Risk Factor study. RESEARCH METHODS AND INSTRUMENTS: In the first 3 days of admission the patients were interviewed by a trained health care professional, who scored the SCL-8D, a somatization questionnaire based on the Whiteley-7 and the CAGE. At discharge, nurses rated the complexity of the patient's care.

RESULTS

Patients with high scores on anxiety and depression (SCL-8D) and on somatization received higher ratings on perceived nursing complexity than those with low scores, with and without control for age, severity of illness and chronicity. The actual nursing intensity and medical care utilization, as measured daily by means of a checklist, could not explain these relations. No differences were found between patients with high or low scores on alcohol abuse.

CONCLUSIONS

The study shows a potential use of screeners for mental disturbances to detect patients for whom nurses might need additional help. However, mental disturbance is not the sole criterion: functional status and other variables that predict medical and nursing care utilization should be included in a screening strategy for case-management programmes.

Detection of alcohol problems in primary care outpatients under different conditions

Outpatients from two primary care clinics in a county hospital were screened for alcohol problems under three conditions. The objective was to determine whether patients would report more drinking and alcohol-related problems if self-report information was gathered in a research setting and/or if patients knew that their doctors would not be informed about their self-reports. The data indicate that patients' self-reports of alcohol consumption or problems were not affected by their knowledge that doctors would know their responses, and that interviews conducted in medical settings did not corrupt self-report data.

Detection by the CAGE of alcoholism or heavy drinking in primary care outpatients and the general population

There is a need to improve the diagnosis of alcoholism in clinical settings because alcoholism, particularly in its early stages, is often unrecognized in general medical practice and in hospitals. In this study the CAGE questionnaire was used to detect alcoholism or heavy drinking in three populations, namely, alcoholics in treatment (ALC), primary-care outpatients (PC), and the general population (GP). Nearly all the ALC tested positive on the CAGE (97.8%), both for current (past year) and for lifetime alcohol-related problems. Among the PC subjects, 44.8% tested positive for lifetime alcohol problems, but the prevalence decreased to 17.2% when only past-year problems were considered. Likewise, 38.3% of the GP sample tested positive for lifetime, but half of these did not meet the 1-year recency criterion. Compared to DSM-III-R criteria during the same time intervals, the sensitivity/specificity of the lifetime CAGE was 91.2%/84.0% and 76.9%/85.1% in the PC and GP, respectively. The corresponding sensitivity/specificity of the past-year CAGE was 94.4%/97.0% and 74.6%/91.6%, respectively. Thus, the CAGE is an appropriate screening test for alcohol problems in these two populations, but other confirmatory tests or interviews are necessary to eliminate false positives. There were neither gender nor racial differences in the ALC sample responses to individual CAGE questions. However, there were gender differences in the PC and GP samples, with more males responding yes to each of the questions. The gender differences probably reflected the higher prevalence of heavy drinking and alcoholism among males.
