Adult long-term health-related quality of life of congenital hydrocephalus patients

Abstract

Object: Congenital hydrocephalus has a major impact on the lives of patients and their relatives, as well as their long-term neurological development and social integration. The aim of this study was to assess the self-reported health-related quality of life (HRQOL) of patients after reaching adulthood.

Methods: A total of 31 patients who required CSF shunt treatment for congenital hydrocephalus within the 1st year of life (between 1963 and 1987) agreed to undergo a structured SF-36 self-assessment. An age-matched German standard cohort was used as control. Additional parameters of surgical, social, and global neurological outcome were analyzed. The mean patient age was 35 years (range 26-51 years, 13 females and 18 males). Hydrocephalus etiologies were posthemorrhagic hydrocephalus (n = 9), postinfectious hydrocephalus (n = 5), aqueductal stenosis (n = 10), myelomeningocele (n = 2), and unknown cause (n = 5).

Results: The mean modified Rankin Scale score was 1.6 (range 0-4). Hydrocephalic patients achieved lower scores for the SF-36 items physical functioning (70.5 vs. 93.5, p < 0.05), physical role functioning (74.2 vs. 88.3, p < 0.05), and general health perceptions (64.5 vs. 72.3, p < 0.05). Emotional, social role functioning, and mental health items did not differ between the groups. Assessment of vitality and pain resulted in a trend to worse values. Whereas the Physical Component Summary score was lower (46.1 vs. 54.3, p < 0.05), the Mental Component Summary score was not significantly different (50.2 vs. 48.7, p = 0.3). There was neither a statistically significant difference between subgroups of different etiologies nor an association with the number of subsequent hydrocephalus-related surgeries.

Conclusions: Adult HRQOL for patients with congenital hydrocephalus appears to be similar to that for healthy con with regard to mental health and social functioning aspects. Physical impairment is a predominant factor of compro quality of life.
