Can A Swallow Screen Score Be Used To Prioritise Dysphagia Assessments By A Speech And Language Therapist?

Abstract

Abstract Background Dysphagia refers to any difficulty or discomfort associated with eating or swallowing. The prevalence is 10-50% in older persons and is associated with increased dependency and mortality. A non-validated Swallow Screen (SwSc) is used by a Community Specialist Team (CST) for older persons during Comprehensive Geriatric Assessment (CGA) to identify patients requiring Speech and Language Therapy (SLT) referral. The SwSc comprises 7 questions with “yes” or “no” answers. “Yes” answers score 1 point and “no” score 0. The SwSc score is the sum of these points. Higher scores indicate the presence of more symptoms of dysphagia. Patients with a SwSc score ≥1 are referred to an SLT. This study aimed to investigate if a higher SwSc score might indicate more severe dysphagia requiring more urgent assessment by an SLT. Methods This was a retrospective cohort study of patients ≥64 years referred to SLT by a CST from June 2023 to April 2024 inclusive. The SLT assessment included a Dysphagia Outcome Severity Scale (DOSS) score. The DOSS score ranges from 1-7, a lower score indicating a more severe dysphagia. Data was entered onto an Excel database and analysed. Biographical and CGA data was analysed using descriptive statistics. The SwSc and DOSS scores were ranked and compared using Spearman’s Rank Correlation Coefficient. Results Thirty-nine patients attended an SLT assessment. The mean age was 78, (SD=8.04). The mean Clinical Frailty Score 5 (SD=1.16) and mean modified Barthel Index score 16 (SD=3.75). There was a negative correlation between the SwSc and DOSS scores, r (37) = -.438, p=.005. Higher SwSc scores were associated with lower DOSS scores, indicating more severe dysphagia. Conclusion The SwSc can be easily administered by non-SLT clinicians. It may be used by an SLT to aid prioritisation of patients for assessment. Further research with a larger sample is required to establish its validity.
