  1. Resident Correction Factor” = Mean monthly employed residents for Reference year/Intervention year
  2. “Procedural Correction Factor” = Total specialist procedural production for reference year/intervention year
  3. Specialist production = Total procedural production for departments-residents production
  4. Standardized Specialist Production = Intervention year total production-(intervention year residents’ production*resident correction factor)
  5. Difference in specialist production = (Standardized Specialist production-Reference year specialist production)*Procedural Correction Factor
  6. Return on time invested = Difference in Specialist Production*Estimated Specialist time spent for performance of each procedure
