The Course of Sleep Disturbances in Early Alcohol Recovery: An Observational Cohort Study

Authors


Abstract

Introduction

Understanding the course and determinants of sleep disturbances in alcoholic patients may help identify patients at high risk of persistent sleep problems, relapse and guide treatment interventions.

Methods

We prospectively administered the Pittsburgh Sleep Quality Index (PSQI) to all patients (N = 196) admitted to a 1-month residential treatment program. Our analysis excluded patients with active drug abuse/dependence. Demographic data, psychiatric diagnoses, Patient Health Questionnaire-9 (PHQ-9), Alcohol Use Disorders Identification Test (AUDIT) and Inventory of Drug Taking Situations (IDTS) scores were obtained. Univariate and logistic regression analyses were performed using sex, age, hazardous alcohol use, PHQ-9 scores, hypnotic use, and use of alcohol as a hypnotic as correlates to admission PSQI scores and improvement in PSQI scores.

Results

A total of 119 alcoholic patients met inclusion criteria (mean age 50.6 ± 13.2 years). The rates of sleep disturbances at admission and discharge were 69.3% and 49.1%, respectively. Self report of using alcohol to fall asleep and use of hypnotics were associated with elevated PSQI scores. Total PSQI scores improved over 4 weeks (p < .001). Change in PSQI scores was not effected by gender, use of hypnotics, hazardous alcohol use, use of alcohol as a hypnotic or co-morbid psychiatric diagnosis. Older age predicted improvement in PSQI scores in patients with sleep disturbances (p = .004).

Conclusion

While a large proportion of alcoholics had sleep disturbances upon admission and at discharge from a residential treatment program, only older age was associated with improvements in sleep disturbances during early alcohol recovery. (Am J Addict 2014;23:21–26)
