Development of the Stroke-unit Discharge Guideline: choice of assessment instruments for prediction in the subacute phase post-stroke.

The purpose of this paper is to present the design of an evidence-based dataset of assessment instruments for the prognostic factors of the Stroke-unit Discharge Guideline (SDG), a consensus based guideline for the decision of the discharge destination from the hospital stroke unit. In our systematic literature reviews and in known standard works we have looked for assessment instruments which are being used most frequently in stroke care, and subsequently we have searched for information regarding their validity and reliability. For 17 out of the 26 prognostic factors we found known applicable assessment instruments. Clinical feasibility and psychometric properties of most of these instruments are sufficient to good. For two factors we had to construct a new instrument. A simple definition was sufficient for the remaining seven factors. The SDG contains an evidence-based dataset of prognostic factors and assessment instruments, and should be applied at the hospital stroke-unit, which is the first location to start with a uniform use of stroke assessment instruments. The SDG assessment instruments are part of the stroke service chain information system, which contains recently developed specifications for application in web-based electronic patient records nationwide in The Netherlands.
