Objective To assess the clinical utility and cost-effectiveness of using MRI Compatible EEG electrode system for patients being monitored in the intensive care unit.

Background Patients undergoing continues video EEG monitoring in the critical care unit often need MR Brain imaging to evaluate for acute change in neurological status. However, EEG electrodes in general are not MRI compatible and replacing electrodes can be expensive, time consuming and an unnecessary waste of manpower.

Design/Methods This retrospective, hospital-based study included 14 critically ill patients who underwent continues video EEG between March 2019 to March 2020. They were classified into 2 age (p=0.579) and gender (p=0.592) matched subgroups: Group 1- ‘MRI-compatible EEG’ (mean age: 56.00±19.99 years; M:F = 2:5; N = 7), Group 2 – ‘Conventional EEG’ (mean age: 49.14±24.76 years; M:F = 4:3; N = 7). The EEG monitoring times as well as cost-effectiveness of continues video EEG between the groups were compared using Mann-Whitney Test (p≤0.05). We also compared the MRI quality between the groups using Chi-squared test (p≤0.05).

Results The EEG non-monitored time in Group 2 (7.62±6.45 hours) was significantly higher than Group 1 (2.71±2.34 hours)] (p=0.025). The average daily cost for continues video EEG in Group 1 ($2098.53±493.58) and Group 2 ($2230.58±142.73) was comparable (p=0.896). The quality of MRI scans between Group 1 (6/7) and 2 (6/7) were also comparable (p=1.000).

Conclusions We found that the amount of EEG monitoring time lost in patients on MRI Compatible EEG electrodes was significantly lower than the patient on Conventional EEG electrodes. At the same time, the daily cost of monitoring and the quality of MRI scans were comparable between the 2 groups. We conclude that the use of MRI Compatible EEG electrodes is a practical and cost-effective method to improve the quality of monitoring in critically ill patients.
