Insights
A new risk score from video recordings shows promise for diagnosing pediatric obstructive sleep apnea-hypopnea syndrome (OSAHS). This tool could improve accessibility for diagnosing this sleep disorder in children.
Area of Science:
- Pediatric Sleep Medicine
- Respiratory Physiology
Background:
- Limited access to polysomnography (PSG) necessitates novel diagnostic tools for pediatric obstructive sleep apnea-hypopnea syndrome (OSAHS).
- Previous research in 1996 suggested a risk score derived from a 30-minute home sleep video recording (VR) shows potential for OSAHS diagnosis.
Purpose of the Study:
- To evaluate the reliability of a risk score derived from PSG video recordings (VR) in children.
- To compare the diagnostic accuracy of risk scores calculated from 30-minute (RS30) and 10-minute (RS10) video segments.
Main Methods:
- A retrospective study analyzed video recordings from 16 children undergoing overnight PSG.
- Seven parameters were assessed to calculate RS30 and RS10 during the second sleep cycle.
- These scores were correlated with PSG-derived obstructive-apnea-hypopnea index (OAHI) and oxygen desaturation index (ODI).
Main Results:
- Both RS30 and RS10 demonstrated significant correlations with OAHI and ODI.
- RS30 predicted an OAHI ≥5/hour with 83% sensitivity and 90% specificity.
- RS10 predicted an OAHI ≥5/hour with 67% sensitivity and 100% specificity.
Conclusions:
- A risk score derived from PSG video recordings correlates well with established PSG measures for pediatric OSAHS.
- These findings support the potential utility of VR-based risk scores for OSAHS diagnosis.
- Future research should focus on validating this score using home-based sleep video recordings for pediatric OSAHS diagnosis.
Objectives:
Because access to sleep recordings is limited, there is a need for new reliable tools for pediatric obstructive sleep apnea-hypopnea syndrome (OSAHS) diagnosis. A score calculated from a 30 minutes-home sleep video recording (VR) has already been proposed in 1996 with interesting results. The main objective of this pilot study was to assess the reliability of a similar score applied to reference PSG VR and calculated on two different time windows (30 and 10minutes).
Methods:
A retrospective monocenter study was made on 16 children suspected of OSAHS, that underwent VR during overnight PSG. Video analysis was made during the second complete sleep cycle. A 30-minute risk score (RS30) and a 10-minute risk score (RS10) were established by analyzing seven parameters. The RS30 and RS10 were correlated with clinical examination data, a sleep questionnaire, the obstructive-apnea-hypopnea index (OAHI) and the oxygen desaturation index (ODI) from synchronized PSG results.
Results:
There was a significant correlation between both the RS30 and RS10, the OAHI and ODI. A RS30 ≥6.09 was predictive of an OAHI ≥5 per hour with a sensitivity of 83% and a specificity of 90%. A RS10 ≥6.50 was predictive of an OAHI ≥5 per hour with a sensitivity of 67% and a specificity of 100%.
Conclusion:
A risk score based on PSG VR shows a good correlation with PSG results, confirming previous reports. Further work should focus on applying this risk score to home sleep VR for the diagnosis of pediatric OSAHS.
