Insights
A videotape demonstrating obstructive sleep apnea (OSA) features did not improve the accuracy of a verbally administered questionnaire for diagnosing pediatric OSA. Standard questionnaires are as effective as video-assisted ones for screening children with sleep-disordered breathing.
Area of Science:
- Pediatric Sleep Medicine
- Respiratory Medicine
Background:
- Obstructive sleep apnea (OSA) is a common sleep disorder in children.
- Accurate screening tools are crucial for early diagnosis and intervention in pediatric patients.
Purpose of the Study:
- To evaluate if a videotape illustrating OSA features enhances the diagnostic accuracy of a verbal questionnaire for pediatric snorers.
- To compare the effectiveness of a standard questionnaire versus a video-assisted questionnaire in predicting OSA.
Main Methods:
- A prospective, single-blinded, randomized controlled study was conducted.
- Parents of pediatric snorers referred for polysomnography (PSG) were randomized to answer either a standard questionnaire (SQ) or a video-assisted questionnaire (VQ).
- The study included children aged 0-18 years.
Main Results:
- The areas under the receiver operating characteristic curves (AUCs) for OSA screening were similar for both SQ (0.709) and VQ (0.714).
- Both questionnaires demonstrated reasonable negative predictive values for ruling out OSA.
- No significant difference in diagnostic accuracy was observed between the two methods.
Conclusions:
- The addition of a videotape showing OSA features did not improve the accuracy of a verbally administered questionnaire.
- A standard questionnaire is as effective as a video-assisted questionnaire for screening pediatric OSA.
- These findings suggest that simpler screening methods may suffice for identifying children at risk for OSA.
Objective:
To determine if watching a videotape that shows features of obstructive sleep apnea (OSA) will improve the accuracy of a verbally administered questionnaire in the prediction of OSA in pediatric snorers.
Patients And Methods:
In a prospective single-blinded, randomized, controlled study at a pediatric clinic for sleep-disordered breathing, we studied children aged 0-18 years, who had been referred to a sleep laboratory for overnight polysomnography (PSG), and their parents from November 1999 to November 2000. The parents were randomized to answer a standard verbally administered panel of three questions (SQ) or a verbally administered panel of questions assisted by videotape (VQ).
Results:
The parents of 52 and 56 pediatric snorers were assigned to answer SQ and VQ, respectively. The areas under the receiver operating characteristic [ROC] curves (AUCs) for screening of OSA in patients were similar at 0.709 (95% confidence interval (CI)=0.561-0.851) for SQ and 0.714 (95% CI=0.571-0.858) for VQ. The two questionnaires had a reasonable negative predictive value to rule out the presence of OSA (VQ=0.816 and 95% CI=0.726-0.885, SQ=0.828, 95% CI=0.714-0.913).
Conclusion:
The addition of a videotape showing important features of OSA achieved no better accuracy than a standard questionnaire.
