This research aims to facilitate the successful implementation of the new Heart and Stroke Foundation of Ontario dysphagia screening model for acute stroke patients. The objectives will be 1) to determine the natural history of dysphagia screening skill decay, and 2) to assess the benefit of independent web-based practice and periodic feedback on screening skill maintenance. We will enrol a convenience sample of nurses who currently work with stroke patients but who have had no prior formal training with dysphagia screening.
