Alcohol Withdrawal Assessment Tool: Validity and Reliability Testing in Acute Care

Alcohol Withdrawal Assessment Tool (AWAT) Reliability and Validity: Implications for Nurses Caring for Inpatients With Mental Health Disorders

BACKGROUND

Alcohol use affects 14.5 million Americans and high prevalence of use and potential for withdrawal among hospitalized patients presents a challenge for health care professionals to anticipate and manage effectively. Due to the acuity and fast-paced nature of the hospital environment, nurses need assessment tools that can be readily completed and drive efficient protocol-based treatment. The purpose of this study was to examine psychometric properties of the alcohol withdrawal assessment tool (AWAT).

AIMS

The aims were to examine AWAT (1) reliability, (2) validity, and (3) usability.

METHODS

Patients (n = 55) and nurses (n = 47) were recruited from six hospitals within one health care system in the Midwest. Psychometric testing included inter-rater reliability and criterion-related validity testing, using the Clinical Institute Withdrawal Assessment of Alcohol Scale-Revised (CIWA-Ar) as a comparison. Usability was assessed with a 5-item Likert-type scale.

RESULTS

Findings supported strong agreement (ICC: .931) between raters on the AWAT and a moderate correlation (Pearson r: .548) between scores on the AWAT and CIWA-Ar. Nurses agreed/strongly agreed that the AWAT took 2 min or less to complete (n = 42; 89%), was easy to use for assessment (n = 42; 89%) was easy to learn (n = 40; 85%), and they were confident using the AWAT (n = 39; 83%).

CONCLUSIONS

Study findings provide evidence of reliability, validity, and usability of the AWAT in the hospital setting. The AWAT has potential to improve assessment efficiency and nurses caring for inpatients with mental health disorders should consider implementing the tool into practice.

Evaluation of the course and treatment of Alcohol Withdrawal Syndrome with the Clinical Institute Withdrawal Assessment for Alcohol - Revised: A systematic review-based meta-analysis

BACKGROUND

Although the Clinical Institute Withdrawal Assessment for Alcohol - Revised (CIWA-Ar) is a gold standard tool for the clinical evaluation of alcohol withdrawal syndrome (AWS), a systematic analysis using the total scores of the CIWA-Ar as a means of an objective follow-up of the course and treatment of AWS is missing. The aims of the present study were to systematically evaluate scientific data using the CIWA-Ar, to reveal whether the aggregated CIWA-Ar total scores follow the course of AWS and to compare benzodiazepine (BZD) and non-benzodiazepine (nBZD) therapies in AWS.

METHODS

1054 findings were identified with the keyword "ciwa" from four databases (PubMed, ScienceDirect, Web of Science, Cochrane Registry). Articles using CIWA-Ar in patients treated with AWS were incorporated and two measurement intervals (cumulative mean data of day 1-3 and day 4-9) of the CIWA-Ar total scores were compared. Subgroup analysis based on pharmacotherapy regimen was conducted to compare the effectiveness of BZD and nBZD treatments.

RESULTS

The random effects analysis of 423 patients showed decreased CIWA-Ar scores between the two measurement intervals (BZD: d = -1.361; CI: -1.829 < δ < -0.893; nBZD: d = -0.858; CI: -1.073 < δ < -0.643). Sampling variances were calculated for the BZD (v₁ = 0.215) and the nBZD (v₂ = 0.106) groups, which indicated no significant group difference (z = -1.532).

CONCLUSIONS

Our findings support that the CIWA-Ar follows the course of AWS. Furthermore, nBZD therapy has a similar effectiveness compared to BZD treatment based on the CIWA-Ar total scores.

Delirium Tremens in the Older Adult

INTRODUCTION

Caring for patients experiencing alcohol withdrawal syndrome can be challenging. Patients 65 and older are at increased risk for alcohol withdrawal syndrome related complications. The higher prevalence of co-morbidities, including cognitive impairment, longer drinking history and greater sensitivity to alcohol withdrawal syndrome treatment are the result of decreased ability of the brain to adapt to stressors such as illness, trauma, or surgery.

DELIRIUM TREMENS

Symptoms may appear earlier from the last drink and present with a wide range of symptoms. The most effective interventions require high-quality nursing care delivery to prevent, decrease the severity and shorten the duration of delirium.

NURSING IMPLICATIONS

Strategies that help minimize these challenges starts with obtaining the patient's selfreport of their alcohol use history. Nurses should be diligent in their monitoring for signs of active alcohol withdrawal. Screening and assessment tools such as the Clinical Institute Withdrawal Assessment for Alcohol-Revised should guide pharmacological management. To support nurses in identifying delirium tremens, this manuscript seek to describe the underlying pathophysiology, key assessment components and nursing management of delirium tremens in the older adult.
