Objective: Survivors of intensive care often present long-term sequelae, including cognitive impairment and psychological discomfort. Follow-up programs have therefore been developed to assess and manage these long-term complications. Studying the effectiveness of such programs can be limited by the number of patients lost during follow-up. The aim of this study was therefore to evaluate patient characteristics predictive of participation to an intensive care unit (ICU) follow-up program.
Design: In this prospective, nested, case-control study, all patients with an ICU stay of at least five days were invited to participate in an ICU follow-up program. Having attended 2 follow-up sessions at ICU and hospital discharge, they were given an appointment for their 3-month follow up. Patients were divided into two groups (“participants and “non-participants”) according to whether or not they attended this appointment. Multivariable logistic regression analysis was used to identify independent predictors of participation.
Settings: An ICU follow-up program from a mixed ICU at a university hospital.
Participants: All patients selected to participate to the ICU follow-up program were included in this study. They were allocated into two groups depending on their attendance in the follow-up program.
Main results: Of the 199 patients included during the study period, 80 (40.2%) were classified as “participants”. These patients had a lower Charlson Comorbidity Index, a longer ICU length of stay (LOS), more frequently received ventilatory support for at least 24 hours and more frequently received extracorporeal membrane oxygenation (ECMO) than non-participant patients. In the multivariable analysis, ICU LOS longer than 10 days was associated with a 3.3 times increased likelihood of participating in the follow-up; a lower Charlson Comorbidity Index also predicted an increased likelihood of participating to the ICU follow-up clinic.
Conclusions: Fewer comorbidities and longer intensive care LOS were independent predictors of participation in ICU follow-up.
