How many surgeons does a province need, and how do we determine appropriate numbers?

Area of Science:

• Health Services Research
• Surgical Specialties
• Healthcare Policy

Background:

• Healthcare resource planning often focuses on the supply of surgical specialists.
• Understanding the relationship between specialist supply and procedure rates is crucial for effective planning.

Purpose of the Study:

• To investigate the association between the supply of surgeons in specific specialties and the rates of related surgical procedures performed in Canadian provinces.
• To determine if surgeon supply is a significant predictor of surgical procedure volume.

Main Methods:

• Comparative analysis of provincial surgeon supply data for ophthalmologists, orthopedic surgeons, and cardiac and thoracic surgeons.
• Correlation analysis with population-based rates of cataract removal, hip and knee replacement, and coronary artery bypass grafting procedures.
• Utilized publicly available health administrative data for the study period.

Main Results:

• A weak or non-existent relationship was observed between the supply of surgical specialists and the rates of key procedures performed.
• No significant correlation found between the number of surgeons in ophthalmology, orthopedic surgery, or cardiac/thoracic surgery and the respective procedure volumes.
• Findings suggest that factors other than specialist supply significantly influence surgical procedure rates.

Conclusions:

• The supply of surgical specialists is not a primary driver of surgical procedure rates.
• Healthcare resource planning should shift focus away from solely increasing specialist numbers.
• Alternative factors influencing access to and utilization of surgical services require further investigation.
