How Volume of Neurosurgical Interventions Impacts Patient Outcomes: An Analysis of 30,000 Craniectomies and Craniotomies
Authors' conclusion
More than half of the patients with traumatic SDH >10 mm did not receive NSI as per Brain Trauma Foundation guidelines.
Study context
- Population
- Adult trauma patients with traumatic subdural hematoma (SDH) >10 mm, ACS TQIP 2017–2021; penetrating injury, nonsurvivable trauma, care-limiting advance directives or ED death excluded
- Participants
- 67,324 patients · 293 trauma centers (TCs)
- Exposure
- High vs middle vs low neurosurgical intervention volume trauma centres
- Outcome
- In-hospital mortality and favourable discharge
Methodological detailsregistry (ACS TQIP), multivariable regression
- Registry (ACS TQIP)
- Multivariable regression
Main finding
As reported in the abstract
- Greater neurosurgical volume associated with lower in-hospital mortality and higher favourable discharge
- P <0.001
- Neurosurgical intervention (NSI) at high-volume vs low-volume TCs: less likely to die (multivariable)
- 23%
- NSI at high-volume vs low-volume TCs: more likely discharged home or to rehabilitation (multivariable)
- 53%
Observational data: associations, not effects.
Further findings
NSI rate
- Underwent NSI
- 45.5%
