Laparoscopic hernia surgery rate

Dr. Zemis’s laparoscopic hernia surgery rate is similar to the rate we predicted for his mix of cases and patients.
14%
laparoscopic hernia surgery rate

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. Zemis’s rate of laparoscopic hernia surgery compares to a typical doctor who performs hernia surgeries:

  1. We first measure how many of Dr. Zemis’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. Zemis’s.

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

Outpatient gallbladder removal rate

Dr. Zemis’s outpatient gallbladder removal rate is similar to the rate we predicted for his mix of cases and patients.
77%
outpatient gallbladder removal rate

As a patient, you may prefer a doctor who has a higher rate of outpatient gallbladder removal to improve your odds of having an uncomplicated recovery after 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

Hospitalizations are costly and associated with a higher risk of infections, so avoiding unnecessary hospital stays can save money and improve your odds of having an uncomplicated recovery after surgery. Gallbladder removals are commonly performed in an outpatient setting, avoiding hospitalizations altogether.

To help you understand how Dr. Zemis’s rate of outpatient gallbladder removal compares to a typical doctor who performs gallbladder removals:

  1. We first measure how many of Dr. Zemis’s gallbladder removals were performed in an outpatient setting.
  2. We then analyze the typical practices of all other doctors in the United States who perform gallbladder removals, using a data-driven model to predict the rate of outpatient gallbladder removal for patients like Dr. Zemis’s.

By comparing these two numbers, you can see whether Dr. Zemis’s rate of outpatient gallbladder removal is lower than, similar to, or higher than predicted.

Hospitalizations are costly and associated with a higher risk of infections, so avoiding unnecessary hospital stays can save money and improve your odds of having an uncomplicated recovery after surgery. Hernia surgeries are commonly performed in an outpatient setting, avoiding hospitalizations altogether.

Same-day biopsy rate

Dr. Zemis’s same-day biopsy rate is similar to the rate we predicted for his mix of cases and patients.
63%
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. Zemis’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. Zemis’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. Zemis’s.

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