Factors associated with sleep quality in patients undergoing cardiac surgery: A longitudinal study

Abstract

Background: Poor sleep quality is associated with multiple factors in cardiac surgery patients. Aim: To examine the trajectory of sleep quality and its associated factors over 3 months in Taiwanese patients undergoing cardiac surgery. Study Design: A longitudinal study. This study enrolled 95 patients undergoing cardiac surgery in northern Taiwan. Sleep quality was measured using the Pittsburgh Sleep Quality Index and Epworth Sleepiness Scale before surgery, at discharge, and at 1 month and 3 months postsurgery. Results: The majority of participants reported poor sleep quality before cardiac surgery (76.8%) and at discharge (81.6%), and they showed significant improvements in sleep quality at 1 month (B = −0.93, p =.023) and 3 months postsurgery (B = −1.50, p
