CoMind Early Feasibility Study
Condition(s) studied
Study summary
The purpose of this research, which has been determined as non-significant risk by the central IRB overseeing the study, is to obtain information to help further develop a machine (a medical device) to measure the pressure around the brain from the outside (this pressure is called intracranial pressure or ICP). Monitoring and managing ICP is an important part of care for patients with conditions such as Traumatic Brain Injury (TBI). However, the current way of measuring ICP requires surgery to drill a hole into the skull, and therefore can introduce additional risks such as infections and pain.
Recent research has shown it may be possible to measure ICP without needing surgery. This technology is in development, but large amounts of data is required to build these new devices.
Through collecting a large database of information from patients who have both the routine surgical device and the research device applied to their head, the research team will work to develop and test an effective and potentially safer way of monitoring patient ICP.
Eligibility
Primary outcome measure(s)
- A test of the difference in estimation errors between two non-invasive ICP estimation models: one trained with ABP and CoMind One EFS CBFi, and one trained only using ABP — From enrollment to the end of observation (either 3 weeks after removal of the CoMind device or until ICU discharge, whichever event is sooner)
- Models trained using CoMind CBFi and ABP will be evaluated based on their limits of agreement (LOA) with invasive ICP. — From enrollment to the end of observation (either 3 weeks after removal of the CoMind device or until ICU discharge, whichever event is sooner)
The threshold limit of agreement will be evaluated at three levels corresponding to a model with clinical utility that is optimal, high, or moderate clinical utility. These levels of clinical utility are defined as follows: ● Optimal clinical utility: a model trained using CoMind CBFi and ABP can achieve LOA with invasive ICP less-than or equal to +/-2 mmHg in the range of ICP between 10-30 mmHg, and less-than or equal to +/-4 mmHg in the ranges of 0-10 mmHg, and 30-50 mmHg. ● High clinical utility: a model trained using CoMind CBFi and ABP can achieve LOA with invasive ICP less-than or equal to +/-3 mmHg in the range of ICP between 10-30 mmHg, and less-than or equal to +/-5 mmHg in the ranges of 0-10 mmHg, and 30-50 mmHg. ● Moderate clinical utility: a model that achieves LOA with invasive ICP less-than or equal to +/-4 mmHg in the range of ICP between 10-30 mmHg, and less-than or equal to +/-6 mmHg in the ranges of 0-10 mmHg, and 30-50 mmHg.
