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

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 />
There is no “best” screen<br />
