This is a protocol for a Cochrane Review (Intervention). The objectives are as follows:

Our main objective is to assess the effectiveness of follow‐up services for ICU survivors that aim to identify and address unmet health needs related to the ICU period. We aim to assess the effectiveness in relation to health‐related quality of life, mortality, depression and anxiety, post‐traumatic stress disorder, physical function, cognitive function, ability to return to work or education and adverse events.

Our secondary objectives are, in general, to examine both the various ways that follow‐up services are provided and any major influencing factors. Specifically, we aim to explore: the effectiveness of service organisation (physician versus nurse led, face to face versus remote, timing of follow‐up service); possible differences in services related to country (developed versus developing country); and whether participants had delirium within the ICU setting.
