Risk Factors for Chronic Subdural Hematoma after a Minor Head Injury in the Elderly: A Population-Based Study

Abstract EN

Chronic subdural hematoma (CSDH) is one of the major comorbidities in elderly resulting in disability and death.

Early recognition of CSDH is important for early management.

However, manifestations of CSDH are nonspecific and subtle.

Therefore, identification of risk factors of CSDH can offer clinical follow-up strategies for patients after episodes of head injury.

The purpose of the study aimed at identifying risk factors of CSDH of Taiwanese.

Analysis of data from the National Health Insurance provides important information on predictive factors influencing the early diagnosis of CSDH in elderly patients following minor head injuries.

The current study is the first nationwide population-based study in Taiwan, showing that old age (≥75 years), male gender, and coexisting hydrocephalus are significantly predictive factors, irrespective to their medical comorbidities.
