About

Background and Rationale:

Traditionally, stroke rehabilitation studies have been performed in stroke patients beyond the first one to three months poststroke [Stinear et al. 2013; Veerbeek et al. 2014]. Acknowledging that early stroke rehabilitation should be initiated soon after stroke onset to optimize stroke outcomes, it is has been stressed that stroke rehabilitation trials should be initiated within the first month [Stinear 2013].

Early stroke rehabilitation trials face difficulties regarding patient recruitment with corresponding low enrollment rates [AVERT 2015; Winters 2015]. Explanations are for example priority given to (sub)acute medical interventions, highly dynamic situation at a stroke unit, and a more rapid change in patients' abilities when compared to patients in later stages poststroke. With the low enrollment rates (~7%), the generalizability of study results is questionable.

Participant screening methods and procedures for research eligibility are part of the patient selection and recruitment process in clinical trials. However, no information is available regarding screening procedures and methods for these early initiated stroke rehabilitation trials, including reasons for not enrolling patients. This knowledge is essential to improve screening procedures and methods, in order to optimize patient enrollment and with that, increase the generalizability of study results.

Objective:

The objective of this project is to evaluate screening methods and procedures for stroke rehabilitation research.

Study Design:

Observational study

Full description

Objective:

The objective of this project is to evaluate screening methods and procedures for stroke rehabilitation research in the Department of Neurology, University Hospital Zurich.

Outcome:

Enrollment rates (defined as the number of patients enrolled per month of recruitment), reasons for non-enrollment, and estimated costs for screening for early stroke rehabilitation studies.

Study Design:

Observational study

Enrollment: 845 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers
