Generic and disease-specific health-related quality of life in patients with Hirschsprung disease: A systematic review and meta-analysis.

Abstract

BACKGROUNDPatients with Hirschsprung disease (HD) are at risk of persistent constipation, fecal incontinence or recurrent enterocolitis after surgical treatment, which in turn may impact physical and psychosocial functioning. Generic health-related quality of life (HRQoL) and disease-specific health-related quality of life are relevant outcome measures to assess the impact of HD on the QoL of these patients. AIMTo summarize all available evidence on HRQoL of patients with HD after surgery and the impact of possible moderating factors. METHODSPubmed, Web of Sciences, PsycInfo and Embase were searched with search terms related to ‘Hirschsprung disease’, ‘Pediatrics’ and ‘Quality of life’. Mean and standard deviation of generic HRQoL overall and domain scores were extracted from each study, as well as data describing potential factors associated with QoL. Random effect models were used for meta-analytic aggregation of generic HRQoL scores. Meta-regression was used to assess the relationship between patient and clinical characteristics and generic HRQoL. Disease-specific HRQoL outcomes of patients with HD were systematically reviewed. RESULTSSeventeen articles were included in the systematic review (n = 1137 patients) and 15 in the quantitative meta-analysis (n = 1024 patients). Four studies reported disease-specific HRQoL. Patient’s age ranged between 0 and 21 years. Meta-analytic aggregation showed a non-significantly impaired generic HRQoL (d = -0.168 [95%CI: -0.481; 0.145], P = 0.293, I2 = 94.9) in patients with HD compared to healthy controls. Physical (d = -0.042 [95%CI: -0.419; 0.335], P = 0.829, I2 = 95.1), psychosocial (d = -0.159 [95%CI: -0.458; 0.141], P = 0.299, I2 = 93.6) and social HRQoL (d = -0.092 [95%CI: -0.642; 0.457], P = 0.742, I² = 92.3) were also not significantly lower compared to healthy controls. There was no relation between health-related outcomes and the sex of the patients and whether generic HRQoL was measured by parental proxy or self-report. Disease-specific complaints of patients with HD impaired physical HRQoL, but not psychosocial and social HRQoL. CONCLUSIONIn this systematic review and meta-analysis, no evidence was found for impaired generic HRQoL in patients with HD compared to healthy controls, neither for moderating effects of sex, parental proxy or self-report.
