비디오 투시 연하 검사에 근거한 연하곤란 임상 척도의 타당도 평가

초록

Objective: Dysphagia is one of the important determinants of the prognosis for various diseases. Clinical dysphagia scale (CDS) was developed to screen dysphagia after stroke. We aimed to reevaluate this scale with comparison to the videofluoroscopic swallowing study (VFSS) findings. Method: Retrospective chart reviews were completed on 677 dysphagic patients undergoing the VFSS from July 2000 to January 2004. CDS was evaluated by a physiatrist before the VFSS. Functional dysphagia scale, new VFSS scale, and American Speech-Language-Hearing Association National Outcome Measurement System swallowing scale (ASHA NOMS scale) were evaluated based on the VFSS. The correlations between CDS and these VFSS scales werestudied. In 118 patients, followed up for more than 6 months, the initial CDS were analysed with the follow-up VFSS findings. Results: CDS was correlated with the VFSS findings and also correlated in disease groups other than stroke (p＜0.05). CDS was different significantly between the aspiration, penetration, and normal group classified on the simultaneous VFSS but not on the VFSS after more than 6 months (p= 0.102). Conclusion: We confirmed that CDS was a quantitative clinical tool responding the VFSS findings well and was adoptable to any dysphagic patients irrespective of the causal disorders.
