This research focuses on ICU survivors who experience cognitive impairment. Many people who survive a stay in the intensive care unit face lasting problems with memory, attention, and thinking skills. This study aimed to see if a specific cognitive rehabilitation program could be safely and practically introduced into hospital routines. The goal was not to prove the treatment works perfectly, but to check if the program is feasible for real-world use.
The researchers conducted a randomized controlled trial at four intensive care units located at two Danish university hospitals. They screened 1,679 patients to find those who met the eligibility criteria. Ultimately, 115 patients qualified for the study, and 83 of them were randomly assigned to receive the cognitive rehabilitation intervention known as ICU CogHab. The program was designed to help patients improve their cognitive functions through structured exercises and support.
The study followed participants for six months. The team looked at several outcomes, including how well patients completed the program and whether they stayed in the study. They found that clinical data were largely complete. However, recruiting patients was lower than the researchers had anticipated. Furthermore, keeping patients in the study for the full six months was difficult, with only 40% of participants retained at the end. Completing the cognitive and patient-reported outcome measures was also more difficult to do at the time of ICU discharge.
No serious adverse events or safety concerns were reported during the study. The cognitive rehabilitation intervention appeared to be tolerable for the participants. There were no discontinuations due to safety issues. The study did not report specific numbers for adverse events, but the overall safety profile was considered acceptable for a feasibility trial.
It is important to understand the limitations of this work. This was a feasibility study, not a large-scale evaluation of effectiveness. The recruitment numbers were lower than expected, and retention was challenging. The outcome measures showed substantial variability, meaning results might differ in other settings. Because this is an early feasibility study, people should not overreact or assume the treatment is ready for everyone. The study shows that the program can be introduced, but the timing of assessments and follow-up procedures need further optimization before it becomes standard practice.
For patients right now, this study suggests that cognitive rehabilitation is a promising area to explore. It indicates that such programs can be integrated into routine ICU workflows. However, more work is needed to make the process smoother and to ensure more patients can complete the program. Patients and families should discuss these emerging options with their healthcare providers to understand what is possible in their specific situation.
