Study summary

This prospective, double-blind, randomized, placebo-controlled study aims to evaluate the efficacy and safety of atorvastatin in patients with chronic subdural haematoma. The degree of disability or dependence in daily activities, as well as surgical intervention or recurrence, of the treatment and control groups will be compared.

Read the detailed description

Objectives: Chronic subdural haematoma (CSDH) is a common neurosurgical condition in the elderly population associated with mild head injury. Surgical drainage has been regarded as safe and effective. However, surgical complications including recurrences can result in poor functional outcome and fatality, particularly in the elderly patients. Atorvastatin, an HMGCoA reductase inhibitor and a widely prescribed lipid lowering medication has properties of inflammation modulation and neovasculature promotion.

Hypothesis: Atorvastatin can improve functional outcome in patients with CSDH for both initially non-operatively treated group (estimated to be 10%) and the operative group (90%) by reducing the rate of surgical intervention and recurrence rate.

Design: A prospective multicentre study of 690 consented patients with symptomatic CSDH will be randomised on the day of admission to receive atorvastatin 20 mg or a placebo daily for 8 weeks. All seven regional neurosurgical units in Hong Kong and two units outside Hong Kong, each treating 80-200 patients per annum, have been invited to participate.

Main Outcome Measures: Primary outcome: Modified Rankin Scale (mRS). Secondary outcome: surgical recurrence.

Sample Size: Assuming an absolute 10% improvement in favourable outcome in the Modified Rankin Scale score (mRS 0-3) at 6 months from the control group of 70% to the treatment group 80%, allowing a 10% loss to follow up, a sample size of 690 is required.

Expected Results: A successful study for improving clinical outcome of CSDH, an important illness of the elderly with an annual incidence of 58/100,000 will change clinical practice.

What researchers measure

Primary outcomes

  1. Favourable Modified Rankin Scale (mRS) score

    Modified Rankin Scale score of 0-3

    Time frame: 6 months

Secondary outcomes

  1. Chronic subdural haematoma (CSDH) related surgical intervention

    Recurrence rate in both initially non-operatively treated patients and operative cases

    Time frame: Throughout the study period, an average of 6 months

Other outcomes

  1. Glasgow Outcome Scale (GOS)

    Gross clinical outcome measure which allows standardised descriptions (good recovery, moderate disability, severe disability, persistent vegetative state, and death, with good recovery indicating the best outcome and death indicating the worst) for the degree of recovery in patients with brain damage.

    Time frame: 2 weeks, 8 weeks, 3 months, and 6 months

  2. Imaging diagnosis

    Computed Tomography (CT) brain scan to exclude the presence of air and new blood in subdural space at 1-2 weeks and to elevate the clarification of CSDH resolution at 3 months and 6 months.

    Time frame: Index admission, 1-2 weeks early post-operation or before discharge, 3 months, 6 months

  3. Barthel Index (BI)

    Ordinal scale used to measure performance in activities of daily living (ADL) which uses 10 variables describing ADL and mobility. Scores range from 0-100 with 0 indicating the worst outcome and 100 indicating the best outcome.

    Time frame: 2 weeks, 8 weeks, 3 months, and 6 months

  4. Montreal Cognitive Assessment (MoCA)

    One-page test for detecting cognitive impairment. The score ranges from 0-30 with a higher score indicating better outcome.

    Time frame: 2 weeks, 8 weeks, 3 months, and 6 months

  5. Modified Rankin Scale

    Scale for measuring the degree of disability or dependence in the daily activities of patients with brain injury.

    Time frame: 2 weeks, 8 weeks, 3 months, and 6 months
