Volume-outcome relationships in neurosurgery

Area of Science:

• Neurosurgery
• Health Services Research

Background:

• Increasing surgeon and hospital volumes are linked to improved outcomes in various neurosurgical conditions.
• This includes metrics like mortality, complication rates, length of stay, and hospital charges.

Purpose of the Study:

• To examine the correlation between surgical/hospital volume and patient outcomes in neurosurgery.
• To inform practice and referral patterns for optimizing patient care through centralization.

Main Methods:

• Analysis of outcomes data based on surgeon and hospital case volumes.
• Review of existing literature on volume-outcome relationships in neurosurgery.

Main Results:

• A positive correlation exists between higher surgeon/hospital volumes and improved patient outcomes.
• Key outcome improvements observed in mortality, complications, length of stay, and discharge disposition.

Conclusions:

• Regionalizing care for specific neurosurgical conditions at high-volume centers can enhance population-level outcomes.
• Neurosurgeons should be aware of their practice volume and its impact on patient care and referrals.
