Patients eligible for recruitment in the RESCUE-ASDH will lack capacity to provide informed consent. In the UK, enrolment of such patients will be possible provided that an independent neurosurgeon (i.e. not involved with the trial) is in agreement. After the operation, a researcher will discuss with the patient’s relatives and patients will be asked to provide informed consent, if and when they regain capacity. Would such an arrangement be possible in your unit and allowed by the local laws and regulations? *
