Aspiration in bilateral stroke patients

A validation study

Jennifer Horner, PhD, Scott R. Brazer, MD, MHS and E. Wayne Massey, MD

Speech and Language Pathology Program (Dr. Horner). Department of Surgery, and the Divisions of Gastroenterology (Dr. Brazer) and Neurology (Dr. Massey), Department of Medicine, Duke University Medical Center, Durham, NC.

We validated the predictive accuracy of an "old" regression model in a "new" sample of bilateral stroke patients (N = 38). Abnormal gag reflex and impaired voluntary cough accurately predicted radiographically verified aspiration in both samples. A final model, using both samples, grouped patients into three risk strata: low risk of 14% (cough and gag normal), moderate risk of 46% to 51% (one of two behaviors abnormal); and high risk of 87% (cough and gag abnormal).
