Pediatric polysomnography: the patient and family perspective

The gold-standard test used to diagnose childhood obstructive sleep apnea is polysomnography. However, this test requires an overnight stay at a sleep laboratory and the attachment of multiple sensors to the patient. The long-term impact of this testing on the child and family are not known. We hypothesized that polysomnography does not precipitate acute or chronic psychological effects in children.

A consecutive cohort of children who had undergone sleep studies 2 to 4 months prior to the interview were administered a standardized questionnaire via telephone.

Of the 118 families that were eligible to participate, 67% could be contacted and agreed to participate; 87% of respondents reported the experience to have been satisfactory (mean Likert score of 8.6 ± 2.0 [SD] on a scale of 1-10). Similar levels of satisfaction were reported by parents of children with developmental delay or those who were younger than 3 years. The night's sleep was considered typical in 68% of cases. Sleep was less likely to be typical in children younger than 3 years (47%, p = 0.043). Eight percent of children experienced pain during the study. By caregiver report, of those children who remembered the sleep study, memories were positive in 84%. No child had evidence of serious long-term psychological issues.

The vast majority of children and families found the polysomnography experience to be satisfactory, with no psychological sequelae. However, many children, especially those younger than 3 years, demonstrated sleep patterns different from their usual sleep. The clinical relevance of this finding merits further study. Further research evaluating the generalizability of this study is also needed.
