Quality-of-life of Chinese older adults with post-stroke dysphagia

Abstract

Background: One of the common complications of stroke is dysphagia. Dysphagia can be a disabling problem with negative psycho-social consequences. The effect of dysphagia on quality-of-life is not well understood among the stroke survivors. The Chinese version of Swallow Quality-of-Life Questionnaire can be a reliable instrument to provide a multidimensional evaluation on the impact of post-stroke dysphagia in the population of Hong Kong Chinese older adults.

Objective: To investigate factors associated with the swallowing-related quality-of-life in Hong Kong Chinese older adults with the history of stroke during the post-acute phase, using a disease-specific quality-of-life questionnaire (CSWAL-QOL).

Method: This was a cross-sectional study of 92 stroke survivors, aged over 55. They were recruited from the inpatient wards and out-patient clinics. They were assessed for any dysphagia and its severity by the bedside swallow assessment. The Mini-Mental State Examination and the Chinese version of Swallow Quality-of-Life Questionnaire were used for cognitive and quality-of-life assessment respectively.

Results: The test-retest reliability of the test was moderately correlated (Spearman’s rho 0.62).Participants on modified diet/fluid, on tube-feeding, older age and post-stroke for 1-2 years were observed to have lower CSWAL-QOL score across scales. Conclusion: The effect of ageing appeared to be a factor affecting swallowing-related QOL in stroke survivors, with better QOL in younger participants(age ranged from 55 to 69) and similar QOL in old (age ranged from 70 to 85) and very old (age above 85)participants. No gradual change of QOL was found as post-stroke duration increases. The oral feeding mode and normal food and fluid consistency resulted a better QOL in stroke survivors.
