Predictors of Health-Related Quality of Life in Children with Cyanotic Heart Disease Who Underwent Palliative and Total Repair

Abstract

Background: Studies on predictors of health-related quality of life (HRQOL) in pediatric patients with cyanotic heart disease who are waiting for the next stage and those who have undergone total repair are scarce. Therefore, we aimed to identify such predictors in children who received the modified Blalock–Taussig shunt (MBTS) and those who underwent total repair. Methods: In this historical cohort and concurrent follow-up study, data of children who underwent MBTS at the age of 0–3 years between January 2005 and December 2016 at a super-tertiary care hospital in Southern Thailand were obtained. Children who were alive in December 2017 were recruited to evaluate the quality of life at least 1 year after their operation. Between January and December 2018, the “Pediatric Quality of Life Inventory 4.0 Generic Core Scales” with both child self-report and parent proxy-report scores were used to examine the HRQOL. Multivariate linear regression analysis was performed to identify independent predictors of HRQOL. Beta-coefficient (β) and 95% confidence intervals (95% CIs) were calculated and considered statistically significant at p
