| description | Bright light exposure is as one of the non-pharmacological measures to sleep management in
shift-worker. This study was conducted to determine the effectiveness of bright light exposure in
shift-worker nurses. We performed a systematic review and meta-analysis according to the preferred
reporting items for systematic reviews and meta-analyses (PRISMA) statement and using existing
literature in the following databases: Cochrane Library, Embase, PubMed, Scopus, Web of Science,
to examine any eligible and relevant interventional (randomized controlled trial, experimental and
quasi-experimental studies) which were published by December 31, 2018. The obtained documents
were analyzed using Stata 14.1 and Cochrane Collaboration’s RevMan 5.3. Five studies met eligibility
criteria. Results from fixed-effect meta-analysis of the included studies revealed that the exposure
could decrease the sleepiness levels, complaints related to shift-work, insomnia and increased the
psychomotor error (95% confidence interval (CI): -0.87,-0.43, p=0.000, I2=98.6%), alertness and
daytime sleep duration following night shifts (95% CI: 0.08,0.99, p=0.000, I2=92.7%). However,
in the random effects model, none of them were statistically significant. Although the results of
fixed-effect are in favor of beneficial effects of bright light exposure in shift-worker nurses, the
random effects could not approve these findings. Maybe because of either large heterogeneity
or insufficiency of the number of studies. Besides, because of the low number of studies, it was
impossible to deal with high amount of heterogeneity using subgroup analysis or meta-regression.
So the controversy on this topic continues to persist, which highlights the need for more welldesigned
randomized control trials with larger sample sizes in the future. |
