The total duration of follow-up is 3 months; the primary outcome will then be assessed in a structured interview by telephone.
Primary outcome measure(s) Functional health at 3-month follow-up, as assessed by the modified Rankin scale (mRS) dichotomised as a favorable outcome (mRS 0 - 2) or an unfavorable outcome (mRS 3 - 6)
Secondary outcome measure(s) 1. Death rate at discharge and 3 months
2. Infection rate during hospital admission
3. Length of hospital admission
4. Volume of post-stroke care
5. Use of antibiotics during the 3 months follow-up
6. Functional health using the full ordinal scoring range of the mRS
7. Quality adjusted life years (QALYs)
8. Costs
Sources of funding 1. Netherlands Organisation for Health Research and Development (ZonMw) (Netherlands) (ref: 171002302)
