Trial of Dexamethasone for chronic subdural hematoma
- Chronic subdural hematoma is one of most common neurological disorders, especially among older patients, and is associated with significant morbidity and mortality
- Main stay of treatment for chronic subdural hematoma is surgical evacuation, although it is associated with complications such as recurrence
- Glucocorticoid has been used in the treatment of chronic subdural hematoma for a number of years, and it may reduce the need for surgery or the risk of recurrence
- The study is a randomized controlled trial comparing adult patients with chronic subdural hematoma who received a 2-week course of dexamethasone versus placebo with the primary outcome measured by modified Rankin Score (mRS) at 6 months.
- The study enrolled 750 patients across 23 sites in United Kingdom, with 680 patients completing the study with the primary outcome assessment.
- Over 94% of patients underwent surgical evacuation, with over 97% of cases done during the index admission.
- At six months, 83.9% of patients in the dexamethasone group achieved mRS of 0-3, while 90.3% of patients in the placebo group have mRS of 0-3.
- Patients in the dexamethasone group also did worse in several secondary outcome measures including mRS at discharge and 3 months, mortality and EQ 5D-5L utility score.
- However, patients in the dexamethasone group had a lower rate of needing an operation in subsequent admission (5.1% vs 7.6%) or the need for re-operation (1.7% vs 7.1%).
- Patients in the dexamethasone group also had a significantly higher rate of adverse events.
- Therefore, although dexamethasone treatment potentially reduces the need for repeat operation, it is associated with worse outcome
- However, as over 90% of patients underwent surgery during the index admission, it is not clear whether dexamethasone treatment will reduce the need for an operation for patients treated conservatively at the beginning.
