Patients With Long-stay at ICU: Factors and Evaluation - Feasibility Study

Sponsor: Uppsala University

Summary

Every year, many critically ill patients are admitted to an intensive care unit (ICU). Most stay only a few days, but a smaller group stays much longer. In Sweden, patients treated in the ICU for more than 10 days account for about 35 percent of all ICU days. Little is known about why some patients need prolonged intensive care, or how their lives are affected afterwards. LIFE-ICU is a planned national observational cohort study of adult patients in general intensive care. This record covers the feasibility study that precedes the main study, including its pilot part. The feasibility study does not change the care patients receive. About 200 adult patients who have been treated in a general ICU for more than four days will be included consecutively at the participating ICUs. For each patient, a designated next of kin, usually the family member or friend most involved during the ICU stay, is invited to take part. Information is collected from the medical record about health before admission and about the ICU stay, for example organ support, delirium, nutrition and mobilisation. At ICU discharge, patients answer four questions about distressing memories from the ICU. Six months after final discharge from intensive care, patients are contacted by letter and then by telephone. They answer questions about health status, quality of life, anxiety and depression, post-traumatic stress, fatigue, life satisfaction, frailty, overall function and occupational status. Designated next of kin answer questions about their own life satisfaction, post-traumatic stress and caregiver burden, provided that the patient is alive at the time of follow-up. A selection of patients and next of kin are also invited to an interview about their experiences of intensive care and of recovery. Staff who collect the data answer an anonymous questionnaire about how the data collection worked. The study compares patients whose total ICU stay is more than 10 days with patients whose stay is more than 4 days and at most 10 days. The main purpose of the feasibility study is to find out whether the planned data collection works in practice. This is assessed against criteria set in advance: how many of the eligible patients can actually be included, how complete the collected data are, and how many patients and next of kin respond at six months. The pilot part also provides the estimates needed to plan the main study, such as the proportion of patients who stay in the ICU for more than 10 days and how the measured factors are distributed. Hypothesis: the feasibility study tests the hypothesis that the planned data collection is feasible within routine intensive care and yields data of sufficient completeness and quality to inform the design of the main study. The main study is designed to test the hypothesis that factors present before ICU admission and during the first days of intensive care contribute to a prolonged ICU stay, that some of these factors can be modified, and that they are also associated with worse long-term outcome. The feasibility study is not powered to test this hypothesis. The long-term goal is better knowledge about prolonged intensive care, so that prognostic information can become more accurate, care can be planned more individually, and patients and next of kin can receive better support during and after the ICU stay.
