Description

Swallowing disorders are relatively common after stroke and can persist, causing complications. Mann et al identified risk factors for complications in patients with stroke-related swallowing disorders. The authors are from Royal Perth Hospital and University of Western Australia.


 

Patient selection: stroke patient with post-stroke swallowing disorder

 

Outcome: aspiration, chest infection and/or swallowing impairment in the 6 months after stroke. Patients with swallowing impairment often had not returned to prestroke diet.

 

Patient assessment: clinical exam and videofluorscopy of swallowing

 

Parameters:

(1) gender

(2) age

(3) oral transit on videofluoroscopy

(4) pentration of contrast into the laryngeal vestibule on videofluoroscopy

where:

• The odds ratios for age and gender were each 5. The odds ratios for oral transient and contrast penetration were each 14.

 

number of risk factors =

= SUM(points for all 4 parameters)

 

Interpretation:

• minimum number of risk factors: 0

• maximum number of risk factors: 4

• The greater the number of risk factors the more likely that the patient will have an adverse outcome within 6 months.

• Delayed or absent swallowing reflex was associated with chest infection.

• Delayed oral transit on videofluoroscopy was associated with a failure to return to a normal diet.
