C-section rate

Dr. Ronan’s C-section rate is higher than the rate we predicted for her mix of cases and patients.
Dr. Ronan 65%
Predicted for her patients 50%
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. Ronan’s C-section rate compares to a typical pregnancy doctor:

  1. We first measure the actual C-section rate for the pregnant patients Dr. Ronan 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. Ronan’s.

By comparing these two numbers, you can see whether Dr. Ronan’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.

Same-day biopsy rate

Dr. Ronan’s same-day biopsy rate is similar to the rate we predicted for her mix of cases and patients.
5%
same-day biopsy rate

As a patient, you may prefer a doctor who has a higher rate of same-day biopsy following mammogram, because early diagnosis of conditions detected by biopsy is important for effective treatment.

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

When a breast tissue biopsy is indicated following a suspicious finding on mammogram, our data indicates that about a third of all biopsies occur on the same day. As a patient, you may prefer a doctor who has a higher rate of same-day biopsy following mammogram, because early diagnosis of conditions detected by biopsy is important for effective treatment.

To help you understand how Dr. Ronan’s rate of same-day biopsy for mammogram compares to a typical doctor who performs mammograms:

  1. We first measure the actual same-day biopsy rate for Dr. Ronan’s patients whose mammograms included a suspicious finding that merited a biopsy.
  2. We then analyze the typical practices of all other doctors in the United States who perform mammograms, using a data-driven model to predict the rate of same-day biopsy for patients like Dr. Ronan’s.

By comparing these two numbers, you can see whether Dr. Ronan’s rate of same-day biopsy 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.
