Health-related quality of life outcomes in children after congenital heart disease surgery in low-middle-income countries: a systematic review and meta-analysis.

INTRODUCTION

Improved treatments for children with congenital heart disease (CHD) have led to a growing interest in long-term functional outcomes such as health-related quality of life (HRQOL). Studies on HRQOL in children with CHD have yielded contradictory results. In this study, we aimed to perform a systematic review and meta-analysis to analyze the effect of surgery on HRQOL outcomes in children with CHD in low-income and middle-income countries.

METHODS

A comprehensive search for articles was performed using the Medline (PubMed), Scopus, and Embase databases from their inception to September 5, 2023. Studies reporting QOL outcomes in children <18 years and published in English were included.

RESULTS

Of the 1239 records screened, 10 studies, including 1721 participants, were included in the study. The overall QOL was significantly better in the control group than in the children who underwent surgery for CHD (=0.04, standard mean difference of -0.62, 95% CI: -1.2 to -0.04), and the overall QOL was significantly better in the children with CHD after surgery than before surgery (=0.05, standard mean difference of -0.56, 95% CI: -1.11 to -0.01).

CONCLUSION

The QOL of children from low-income and middle-income countries who undergo surgery for CHD is significantly poorer than that of controls in all dimensions except the emotional domain. Meanwhile, surgery has the greatest impact on improving the physical domain in children with CHD after surgery. Strategies to improve HRQOL in this subgroup of patients should be further investigated.
