The objective of this study was to examine recruitment in three observational
follow-up studies of patients with stroke, focusing on reasons for
nonparticipation and the role of potential factors in explaining recruitment
rates. It comprised secondary analysis of the three studies. Recruitment rates
varied between the studies. Between 10 and 50% of those screened participated. In
one study with no eligibility criteria other than informed consent being obtained
and a confirmed diagnosis of stroke, we recruited only 50% (95% confidence
interval 47 to 54%) of those screened. Recruitment is particularly difficult when
restricted to a time window around discharge from hospital. We recommend that
potential participants should be approached for consent as soon as possible, so
that data tracking their hospital stay can be retained. Even where effectively no
eligibility criteria are used, recruitment is limited by the necessity to gain
informed consent, particularly amongst patients with severe disease.
