Methods
The study took place at a large acute hospital and its partner community rehabilitation hospital in one city in the UK. The hospital has three neurological wards (an acute stroke unit, stroke rehabilitation and neurological rehabilitation wards), a team of around 20 SLTs and a videofluoroscopy clinic. The study was approved by an ethics panel at the University of Lincoln (reference number 2020-2210) and the local NHS Research and Development team. Patient data was accessed via the electronic patient record and anonymised at the point of collection. Research is reported in accordance with STROBE guidelines (see appendix one) 16.
