About

The goal of this observational study is to better understand how chronic subdural hematoma (CSDH) progresses and how patients are treated and cared for. The study focuses on three main questions:

1. What are the characteristics of patients with CSDH when they are diagnosed?
2. What treatments do patients with CSDH receive?
3. What are the outcomes for patients with CSDH, including their functional ability, cognitive health, and neurological status?

Participants will receive their usual standard treatment. As part of the study, they will complete a brief telephone interview three months after their treatment.

Full description

Rationale:

Chronic subdural hematoma (CSDH) is a common condition encountered by neurologists and neurosurgeons. While guidelines for the management of CSDH have recently been developed, high-quality evidence to inform these recommendations, particularly level I evidence from randomized clinical trials (RCTs), is awaited. Significant variability in the management of CSDH persists at international, national, and inter-hospital levels. To further refine and implement evidence-based guidelines, a detailed understanding of current clinical practices and their associated outcomes is essential.

Objective:

To describe the baseline characteristics, treatment strategies, and outcomes of patients diagnosed with chronic subdural hematoma.

Study design:

A prospective, observational multicenter cohort study.

Study population:

All adult patients diagnosed with chronic subdural hematoma.

Main study parameters/endpoints:

The primary endpoint is functional outcome, measured by the modified Rankin Scale (mRS) at 3 months. Secondary endpoints, also assessed at 3 months, include recurrence, mortality, complications, hospital length of stay, Markwalder Grading Scale (MGS), modified National Institutes of Health Stroke Scale (mNIHSS), and Telephone Interview for Cognitive Status (TICS).

Nature and extent of the burden and risks associated with participation, benefit and group relatedness:

Patients will be treated in accordance with standard clinical practice. Study participation imposes minimal additional burden, consisting of a single telephone interview at three months, estimated to take approximately 10 minutes. The findings from this registry are expected to benefit future CSDH patients by informing evidence-based guidelines and improving care practices.

Enrollment: 1,500 estimated patients

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Patients diagnosed with CSDH
• 18 years or older

Exclusion criteria

• Patients who do not consent to participate in the registry

Trial design

1,500 participants in 1 patient group

CSDH patients

Description:

All adult patients diagnosed with chronic subdural hematoma who provide informed consent to participate in the study will be included. Participants will receive standard care, with treatment determined by their treating physician based on clinical judgment. Treatment options may include burr hole drainage, craniotomy, embolization of the middle meningeal artery, pharmacological management, or a wait-and-scan approach. Follow-up will be conducted at 3 months via a telephone interview.
