Study Notes
3 oz Water Swallow Test
-
Purpose: Evaluates swallowing safety by having patients drink 3 ounces of water uninterrupted.
-
Referral Criteria:
- Inability to complete the task
- Coughing or choking during the test
- Wet or hoarse vocal quality during or within one minute after the test.
Result Interpretations
-
True Positive: Aspiration observed during FEES after failing the test.
-
True Negative: No aspiration observed during FEES after passing the test (indicates no swallowing problem).
-
False Positive: No aspiration observed during FEES despite failing the test.
-
False Negative: Aspiration observed during FEES after passing the test.
Key Points for Interpretation
-
High Sensitivity: 96% of patients who aspirated on FEES failed the 3-ounce test.
-
High Negative Predictive Value: 98% of those who passed the test did not aspirate on FEES. This means if the test is passed, it's highly likely no aspiration occurred.
-
Passing the test: Passing the 3-ounce water test suggests safe tolerance of thin liquids.
-
Low Specificity: 50% specificity for detecting aspiration during FEES. This means many who fail the test might not aspirate during FEES (high false positive rate).
