Assessment of swallowing and referral to speech and language therapists in acute stroke

Abstract

The best clinical assessment of swallowing following acute stroke, in order to decide whether to refer a patient to a speech and language therapist (SLT), is uncertain. Independently of the managing clinical team, we prospectively investigated 115 patients (51 male) with acute stroke, mean age 75 years (range 24-94) within 72 h of admission, using a questionnaire, structured examination and timed water swallowing test. Outcome variables included referral to and intervention by a speech and language therapist (SLT), dietary modification, respiratory complications and death. Of those patients in whom an SLT recommended intervention, 97% were detected by an abnormal quantitative water swallowing test; specificity was 69%. An SLT was very unlikely to recommend any intervention if the test was normal. Inability to perform a water test and/or abnormality of the test was associated with significantly increased relative risks of death, chest infection and dietary modification. A timed water swallowing test can be a useful test of swallowing and may be used to screen patients for referral to a speech and language therapist after acute stroke.
