Computer program could help track progress of brain-injured patients after release from ICU, study finds

. Of the 20 patients the researchers assessed, all exhibited some impairment in areas such as memory, attention and decision-making.

The study, published on Friday in the journal PLOS One, demonstrated the feasibility of using an online assessment tool called the Cambridge Brain Sciences battery to detect cognitive problems in ICU patients. The researchers say they believe this tool, originally developed by Dr. Owen to study people’s cognitive abilities outside of a lab setting, will allow them to better understand why these symptoms occur, and how to prevent and treat them.

Standard neurocognitive assessments, which are administered by specially trained staff, are time-consuming, and require patients to complete them in the hospital or a testing centre, he explains. But since the online Cambridge Brain Sciences tool can be self-administered by patients at home within about 20 minutes, it can allow doctors to easily and frequently monitor their progress.

He says this information may also help doctors and researchers identify the causes of patients’ cognitive symptoms. For instance, they may learn that impaired executive function may be associated with high carbon dioxide levels in patients’ bodies while they were in ICU.
