The effects of critical illness not only affect the patient and relative during the intensive care stay but often affect for a considerable time afterwards. A growing body of opinion and evidence suggests that many of the needs of those who have been critically ill can be met through critical care follow-up services. A growing number of follow-up services now exist. Their establishment, development and evaluation pose significant challenges for those involved. This paper describes Bassetlaw hospital's critical care follow-up service, how it was established and what an elementary service evaluation project has shown. The findings and experiences are compared with others in published literature, and the paper may be of interest to those who are currently involved in follow-up or who plan to develop such services in the future.
