Brief Summary:
An open study evaluating the diagnostic accuracy of a microwave-based device to detect traumatic intracranial hemorrhage (TICH), by comparing measurements on trauma patients with confirmed vs excluded TICH

Condition or disease Intervention/treatment Phase
Traumatic Intracranial Hemorrhage Device: Medfield Strokefinder MD100 Not Applicable

Detailed Description:

This open study will enrol trauma patients admitted to the Trauma Unit, Department of Surgery at Sahlgrenska University Hospital/Sahlgrenska. It will compare patients where TICH has been confirmed by CT (group A) to patients where CT has ruled out TICH (group B). Patients will be asked to participate in the study as early as possible after admission and CT scan. After physical examination, checking inclusion/exclusion criteria, and after informed consent has been acquired, the baseline microwave-based measurement will be performed. The diagnostic procedure is estimated to take 15 min; whereof total subject measurement time will be less than five minutes. Follow-up microwave measurements will be performed in conjunction with any follow-up CTs performed as part of the standard of care, during the hospitalized treatment period. If no follow-up CTs are performed as part of the standard of care, only the baseline microwave measurement will be performed.

Safety will be followed throughout the study, and a safety follow-up will be performed 12 hours after the last microwave-based investigation is finalized.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. The diagnostic ability as measured by the area under receiver operating characteristic curve (AUC) of the device for detecting TICH [ Time Frame: The diagnostic procedure has an estimated duration of 15 minutes ]
    The diagnostic ability of the device is calculated using a leave-one-out/n-fold cross-validation method


Secondary Outcome Measures :
  1. The accuracy for estimating the position of the intracranial hemorrhage through a mathematical analysis of the microwave data [ Time Frame: The diagnostic procedure has an estimated duration of 15 minutes ]
  2. The accuracy for estimating the volume of the intracranial hemorrhage through a mathematical analysis of the microwave data [ Time Frame: The diagnostic procedure has an estimated duration of 15 minutes ]
  3. Mean time (± standard deviation) needed to complete the measurement procedure [ Time Frame: The diagnostic procedure has an estimated duration of 15 minutes ]
  4. Any adverse events occurring within 12 hours from the measurement procedure(s) [ Time Frame: The diagnostic procedure has an estimated duration of 15 minutes, a safety follow-up will be performed 12 hours after the diagnostic procedure ]
