Abstract

Objective: This study aimed to assess the validity and reliability of the developed bedside
swallowing screening test that modified from Standardized Swallowing Assessment (SSA).


Methods: The developed screening test was modified from the SSA form by changing
the amount of water and adding food tests. Three experts appraised the validity of the modified
swallowing screening test. Then, the test was evaluated to 100 acute stroke patients who were
admitted to the acute stroke ward at Ramathibodi Hospital during October - December 2019.
Data were collected by two independent registered nurses. The reliability was calculated
using Cohen’s kappa. Moreover, follow up one month after discharge from the hospital was
made to track that the passed patient had no aspiration pneumonia.


Results: The results showed that confidence (Cronbach’s alpha) of the tool was 0.798.
The interrater reliability for the full assessment was kappa 0.83. The interrater reliability for
each item was Kappa 0.928-1.00. The subjects were mostly male, 62%, with a mean age of
63±15 years old. Ischemic stroke was the typical type of stroke 74%, intracerebral hemorrhage
14%, and TIA 11%. Ninety-four subjects passed the swallowing screening test. All patients
who passed the trial did not have a history of aspiration pneumonia after 1-month follow-up.


Conclusion: The validity of the developed bedside swallowing screening test was 0.798,
with excellent reliability. This developed screening test was beneficial to detect and prevent
the patient at risk of dysphagia in an acute stroke patient.
