Improving post-stroke dysphagia outcomes through a standardized and multidisciplinary protocol: an exploratory cohort study.

Stroke is a major cause of dysphagia. Few studies to date have reported on standardized multidisciplinary protocolized approaches to the management of post-stroke dysphagia. The aim of this retrospective cohort study was to evaluate the impact of a standardized multidisciplinary protocol on clinical outcomes in patients with post-stroke dysphagia. We performed retrospective chart reviews of patients with post-stroke dysphagia admitted to the neurological ward of Verona University Hospital from 2004 to 2008. Outcomes after usual treatment for dysphagia (T- group) were compared versus outcomes after treatment under a standardized diagnostic and rehabilitative multidisciplinary protocol (T+ group). Outcome measures were death, pneumonia on X-ray, need for respiratory support, and proportion of patients on tube feeding at discharge. Of the 378 patients admitted with stroke, 84 had dysphagia and were enrolled in the study. A significantly lower risk of in-hospital death (odds ratio [OR] 0.20 [0.53-0.78]), pneumonia (OR 0.33 [0.10-1.03]), need for respiratory support (OR 0.48 [0.14-1.66]), and tube feeding at discharge (OR 0.30 [0.09-0.91]) was recorded for the T+ group (N = 39) as compared to the T- group (N = 45). The adjusted OR showed no difference between the two groups for in-hospital death and tube feeding at discharge. Use of a standardized multidisciplinary protocolized approach to the management of post-stroke dysphagia may significantly reduce rates of aspiration pneumonia, in-hospital mortality, and tube feeding in dysphagic stroke survivors. Consistent with the study's exploratory purposes, our findings suggest that the multidisciplinary protocol applied in this study offers an effective model of management of post-stroke dysphagia.
