The ability of nursing staff to determine stroke deglutition disorders is crucial in caring for stroke patients. This study aimed to increase the ability of nursing staff in stroke care units to provide accurate diagnoses of this type. Research was carried out using evidence-based metaanalysis to comprehensively determine the most accurate water volume for the diagnosis of stroke deglutition disorders. The diagnostic accuracy of stroke deglutition disorders increased from 4.75% to 100% among nursing staff when the new technique was implemented, and the incidence of aspiration pneumonia in patients with strokes was reduced from 2.59 ‰ to 1.36 ‰ . By applying this meta-analysis of diagnostic tests to clinical practice, nursing staff can increase the diagnostic accuracy of stroke deglutition disorders.
