The RESCUE-ASDH trial is an “associated study” linked with the CENTER-TBI project (https://www.center-tbi.eu/) of the European Brain Injury Consortium
Health Technologies Being Assessed:
Approximately two-thirds of head-injured patients undergoing emergency brain surgery have an ASDH evacuated. When an ASDH is evacuated, the bone flap can be left out or replaced prior to closing the skin. The RESCUE-ASDH trial will compare these two specific components of the operation to remove an acute subdural haematoma (i.e. bone flap left out prior to closing the skin versus bone flap replaced prior to closing the skin). Both options are widely practised and accepted but they have never been compared head-to-head in a randomised trial. When the bone flap is replaced prior to closing the skin, the operation is named craniotomy. On the other hand, when the bone flap is left out, the operation is named decompressive craniectomy (DC). The advantage of a DC is that it is effective in controlling brain swelling which is often a problem in the days after the operation. When the swelling goes down, the patient has another operation to reconstruct the skull (cranioplasty). The advantage of a craniotomy is that the patient will not need a later operation to rebuild the skull. However, it may fail to control brain swelling in some patients.
The study is focusing on adult head injured patients who require an operation to evacuate an ASDH.
– Adult head-injured patients (>16 years)
– Acute subdural haematoma on CT*
– The admitting neurosurgeon feels that the haematoma needs to be evacuated either by a craniotomy or decompressive craniectomy (bone flap at least 11 cm in both instances)*
* Patients with additional lesions (e.g. intracerebral haemorrhage, contusions) can be included
– Bilateral acute subdural haematomas both requiring evacuation
– Previous enrolment in RESCUE-ASDH study
– Severe pre-existing physical or mental disability or severe co-morbidity which would lead to a poor outcome even if the patient made a full recovery from the head injury
Patient enrolment (including screening for eligibility and consent) will occur in hospitals with neurosurgical services in the UK and other countries around the world.
Measurement of Outcomes:
The primary endpoint will be the extended Glasgow Outcome Scale (GOSE) at 12 months post-injury. The use of the GOSE as a core global outcome measure is recommended by the interagency Traumatic Brain Injury (TBI) Outcomes Workgroup and the International Mission for Prognosis and Analysis of Clinical Trials in TBI group (IMPACT).
The secondary endpoints are:
– GOSE at 6 months post-injury
– Quality of life (EQ-5D) at discharge from neurosurgical unit (NSU), 6 and 12 months post-injury
– Glasgow Coma Scale (GCS) on discharge from the intensive care unit (ICU) and from NSU
– Length of stay in ICU, neurosurgical and rehabilitation unit
– Therapy Intensity Level (IMPACT scale) in the ICU
– Discharge destination from NSU
– Serious adverse events & surgical complications during index admission
– Cranial surgery within 2 weeks after randomisation
– Subsequent readmissions to the NSU within the 12 months follow-up period
– Hydrocephalus requiring shunt insertion within the 12 months follow-up period
– Health care services utilisation over 12 months
– Detailed economic evaluation
