Abstract
Introduction: Healthcare workers are especially vulnerable to sleep disturbances, including shift work sleep disorder (SWSD). Even though omega-3 supplementation has been studied to enhance sleep quality in different populations, there is lack of evidence to support its effectiveness in SWSD. This trial aims to evaluate this compound potential benefits towards health care personnel suffering from SWSD. Methods: This study protocol consists of a phase III, single-center, double-blind, placebo-controlled randomized clinical trial. Participants will receive sleep hygiene orientation in addition to either omega-3 dietary supplementation or placebo for 8 weeks. The primary outcome will be sleep quality as measured by the Pittsburgh Sleep Quality Index and one of the secondary outcomes would be actigraphy as a reliable sleep assessment. The sample size will be 136 subjects. Discussion: The importance of improving sleep quality of health care workers relies on its impact on their wellness, and on patient safety. Sleep deprivation and disorders are responsible for multiple workplace errors and worse health outcomes alike. This trial can help determine if omega-3 supplementation can contribute to ameliorate sleep disturbances in health care professionals.
