Laparoscopic hernia surgery rate

Dr. De Mar’s laparoscopic hernia surgery rate is higher than the rate we predicted for his mix of cases and patients.
Dr. De Mar 34%
Predicted for his patients 19%

As a patient, you may prefer a doctor who has a higher rate of laparoscopic hernia surgery to reduce scarring and pain compared to traditional open surgery.

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

Laparoscopic surgery involves smaller incisions, less scarring, and sometimes less pain than traditional open surgery.

To help you understand how Dr. De Mar’s rate of laparoscopic hernia surgery compares to a typical doctor who performs hernia surgeries:

  1. We first measure how many of Dr. De Mar’s hernia surgeries were performed laparoscopically.
  2. We then analyze the typical practices of all other doctors in the United States who perform hernia surgeries, using a data-driven model to predict the rate of laparoscopic hernia surgeries for patients like Dr. De Mar’s.

By comparing these two numbers, you can see whether Dr. De Mar’s rate of laparoscopic hernia surgery 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.
