Factors Associated with Health-Related Quality of Life in Children with Intestinal Failure

Abstract

To evaluate disease-specific and age-related factors contributing to health-related quality of life (HRQOL). in children with intestinal failure. A prospective study of HRQOL was performed in a regional intestinal rehabilitation program. Parent-proxy Pediatric Quality of Life Inventory surveys were administered annually to families of 91 children with intestinal failure over a 6-year period. Survey data was stratified by age and compared with pediatric HRQOL data in healthy and chronically ill populations. Linear mixed-effect models using multivariable regression were constructed to identify associations with HRQOL. A total of 180 surveys were completed by 91 children and their families. HRQOL scores were lowest for children ages 5-7years (P< .001) and 8-12years (P< .01), and these changes were primarily related to school dimension scores. In multivariable regression, age of 5years and older and developmental delay were independently associated with lower HRQOL scores. The trend toward lower HRQOL scores parallels reference data from healthy and chronically ill children, although patients with intestinal failure scored lower than both populations at school age. Children with intestinal failure experience lower parent-proxy HRQOL scores in the 5-7 and 8-12year age groups primarily related to school dimension scores. Multicenter data to validate these findings and identify interventions to improve QOL for children with intestinal failure are needed.
