Administered in the Emergency Department<br />

Pass/Fail Criteria<br />

No liquid or solid trials administered


MetroHealth <strong>Dysphagia</strong> Screen<br />

1. Is alertness level insufficient to remain awake for 10 minutes while<br />

sitting upright?<br />

2. Is voice weak, wet, or abnormal in any way? (If cannot speak, circle<br />

yes)<br />

<strong>Screening</strong> Purpose<br />

Identify individuals with or at risk <strong>of</strong> swallowing<br />

dysfunction following a stroke.


Sensitivity vs. Specificity<br />

Always a trade-<strong>of</strong>f<br />

<strong>Dysphagia</strong> screening is tilted towards sensitivity


The Perfect Screen<br />

Do you have stroke-like<br />

symptoms?


The Perfect Screen<br />

100% Sensitivity to <strong>Dysphagia</strong><br />

0% Specificity to <strong>Dysphagia</strong><br />

Theoretical Result: Never a dysphagia related<br />

complication<br />

<strong>Bedside</strong> Result<br />

6 out <strong>of</strong> 10 patients are angry!


Not all bedsides are the same

Factors that may effect screen choice<br />

Availability <strong>of</strong> Speech Pathology<br />

Availability <strong>of</strong> Radiology Services (i.e. Vide<strong>of</strong>luoroscopy)<br />

Volume <strong>of</strong> patients<br />

Nursing numbers


Fewer Resources Available<br />

May be less tolerant <strong>of</strong> false positives<br />

May be more comprehensive<br />

May resemble an assessment rather than screen<br />

Potentially more burden on nursing


More Resources Available<br />

May tolerate false positives<br />

May be less comprehensive (pass/fail)<br />

Potentially less burden on nursing


No Perfect Screen<br />

Perfection= 100% Sensitivity & 100% Specificity<br />

There will be false positives<br />

There will be false negatives<br />

Conclusion<br />

Much research has been done<br />

Many screens, most are pretty good<br />

When choosing a screen, be objective <strong>and</strong> systematic<br />
