The 3-ounce (90-cc) water swallow challenge: a screening test for children with suspected oropharyngeal dysphagia.

OBJECTIVES

To investigate the clinical utility of the 3-ounce (90-cc) water swallow challenge alone to determine both aspiration status and oral feeding recommendations in children.

DESIGN

Cross-sectional evaluation of a diagnostic test with a consecutive, referral-based sample.

SETTING

Urban, tertiary care, teaching hospital.

PARTICIPANTS

Fifty-six children (age range 2-18 years; mean 13 years) referred for swallowing evaluations.

OUTCOME MEASURES

Aspiration status during fiberoptic endoscopic evaluation of swallowing (FEES) was the objective criterion standard with which results from the 3-ounce water swallow challenge were compared.

RESULTS

Twenty-two (39.3%) participants passed and 34 (60.7%) failed the 3-ounce challenge. Sensitivity for predicting aspiration status during FEES = 100.0 percent, specificity = 51.2 percent, and false-positive rate = 48.4 percent. Sensitivity for identifying individuals who were deemed safe for oral intake based on FEES results = 100.0 percent, specificity = 44.0 percent, and false-positive rate = 56.0 percent.

CONCLUSIONS

If the 3-ounce water swallow challenge is passed, not only thin liquids but diet recommendations with puree and solid food consistencies can be made without the need for further instrumental dysphagia assessment.

SIGNIFICANCE

The 3-ounce water swallow challenge has been shown to be a clinically useful screening test for oropharyngeal dysphagia in children.
