Insomnia Interventions in the Workplace: A Systematic Review and Meta-Analysis

Area of Science:

• Occupational Health
• Sleep Medicine
• Evidence-Based Practice

Background:

• Insomnia is a prevalent issue affecting workforce health and productivity.
• Identifying effective interventions for workplace insomnia is crucial for employee well-being.
• Randomized clinical trials provide robust evidence for intervention efficacy.

Purpose of the Study:

• To systematically review and meta-analyze randomized clinical trials on interventions for insomnia in the workforce.
• To evaluate the impact of these interventions on sleep quality and related work outcomes.

Main Methods:

• Systematic literature search across PubMed, Web of Science, CINHAL, and PsycINFO databases.
• Included 22 studies in the review and 12 in the meta-analysis (14 intervention groups, 827 workers).
• Utilized a random-effects model with the Insomnia Severity Index; assessed bias and evidence quality using Cochrane and GRADE methods.

Main Results:

• Cognitive behavioral therapy was the most common intervention.
• A moderate effect size (MD -2.08) was found for reducing insomnia symptoms post-intervention.
• Interventions improved sleep quality, reduced sleep onset latency, and increased weekly sleep hours.

Conclusions:

• Workplace interventions are effective in improving workers' health by reducing insomnia symptoms.
• Improvements in sleep correlate with enhanced productivity, reduced presenteeism, and decreased job burnout.
• Moderate quality of evidence suggests the need for continued research and implementation of these strategies.
