To evaluate the mortality rate and causes of death in patients undergoing burr-hole drainage for chronic subdural hematoma (CSDH), highlighting the significance of these evaluations.
Key Findings:
13.9% of patients died during a median follow-up of 16.4 months (589 patients).
6-month mortality rate was 6.6%.
Mortality increased with the number of comorbidities: 4.7% (none), 8.0% (one), 14.8% (two), 26.6% (three), 46.2% (four).
Common causes of death included diseases of the circulatory system (34%), accidents (16%), and dementia (15%).
Interpretation:
The study highlights the significant mortality risk associated with CSDH surgery, particularly in patients with multiple comorbidities, and identifies key causes of death post-surgery, emphasizing the need for careful management of comorbidities.
Limitations:
The study is a post hoc analysis, which may introduce biases affecting the reliability of the findings.
Limited generalizability due to the specific population studied (Finnish patients).
Potential inaccuracies in cause of death reporting despite rigorous data collection methods.
Conclusion:
Mortality after surgery for CSDH is considerable, especially among patients with multiple comorbidities, with circulatory diseases being the leading cause of death, underscoring the need for targeted interventions.
