Effect of diary intervention on sleep quality and risk of stress disorders among critically ill children in pediatric intensive care units and on their parents' anxiety level: A randomized controlled trial
Abstract
OBJECTIVES
To investigate benefits of diary intervention in a pediatric intensive care unit (PICU) on sleep quality and stress-related disorders in critically ill children and anxiety and depression in their parents.
METHODS
This single-blind, two-arm, randomized controlled trial enrolled 94 dyads. The control group (n = 47) received standard care; the experimental group (n = 47) additionally received a diary intervention. We compared the sleep quality and stress disorders of children, and anxiety, depression, and stress disorders among parents at various time-points, between groups.
RESULTS
Data of 83 dyads were ultimately analyzed (loss-to-visit rate: 11.7 %). During the PICU stay, the experimental group showed significantly shorter total awakening time of each sleep episode and mean duration of each awakening per sleep session than the control group (P = 0.006; P = 0.032). The Childhood Stress Disorder Checklist scores of children in the experimental group were significantly lower than those in the control group at 1 and 3 months post-discharge (P = 0.003; P = 0.006). Parents in the experimental group reported significantly lower anxiety scores at PICU discharge and 1 month thereafter (P < 0.001; P = 0.015). At discharge, depression scores were significantly lower in the experimental group; this difference remained significant at 1 and 3 months post-discharge (P < 0.001; P < 0.05). At PICU discharge, parental scores were significantly lower in the experimental group than…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 47 participants or records.
