C-section rate

Dr. O'reilly’s C-section rate is similar to the rate we predicted for her mix of cases and patients.
56%
C-section rate
Decision factor

Compared to predicted rates calculated for each doctor’s unique mix of cases and patients

  • Lower than our predicted rate
  • Higher than our predicted rate
  • Similar to our predicted rate

To help you understand how Dr. O'reilly’s C-section rate compares to a typical pregnancy doctor:

  1. We first measure the actual C-section rate for the pregnant patients Dr. O'reilly treats.
  2. We then analyze the typical practices of all other doctors in the United States who deliver babies, using a data-driven model to predict the C-section rate for patients like Dr. O'reilly’s.

By comparing these two numbers, you can see whether Dr. O'reilly’s C-section rate is lower than, similar to, or higher than predicted.

This prediction adjusts based on the types of patients the doctor sees, so a doctor who treats sicker patients may have a different predicted rate than a doctor who treats healthier patients.
