Measuring the Quality of Care at the Cedars-Sinai Center for Minimally Invasive Gynecologic Surgery

Physicians in the Center for Minimally Invasive Gynecologic Surgery have combined surgical volume with state of the art technology to safely perform complex procedures like hysterectomies.

Comparing Hysterectomy Rates Performed Laparoscopically and Using a Traditional Open Approach at the Cedars-Sinai Center for Minimally Invasive Gynecologic Surgery

In a study examining the three surgical approaches to performing a hysterectomy (abdominal, vaginal or laparoscopic), the benefits of the minimally invasive laparoscopic approach compared to the abdominal approach included speedier return to normal activities, less bleeding during surgery, shorter hospital stay and fewer infections. 1, 2

From a cross-sectional analysis of the 2012 Nationwide Inpatient Sample3, among 290,425 hysterectomies, 28.1% were performed laparoscopically, 47.6% abdominally (or open), and 24.3% vaginally. As detailed in the table below, Cedars-Sinai’s CMIGS physicians have performed these cutting-edge laparoscopic hysterectomies at a rate that is nearly double the national average.

Volume and Average Length of Stay for Hysterectomy Patients Treated at the Cedars-Sinai Center for Minimally Invasive Gynecologic Surgery

This quality measure refers to the average number of days a patient stays at Cedars-Sinai Medical Center after being admitted for a hysterectomy. The goal is to ensure that all patients are appropriately treated in the hospital for their respective conditions and are not hospitalized longer than necessary. Studies show that patients who spend less time in the hospital after surgery will have fewer complications.4,5,6

As detailed in the chart below, laparoscopic hysterectomies performed by Cedars-Sinai's CMIGS physicians resulted in a consistently shorter length of stay, currently less than the national average.

7 Expected length of stay is calculated by UHC based on patients with similar clinical characteristics. The University Health Consortium (UHC) more than 300 of the nation’s non-profit academic medical centers and their affiliated hospitals.  The majority of these facilities participate in UHC's Clinical DataBase/Resource Manager.  The data  was accessed on May 20, 2015.  Patient populations are defined as follows:  laparoscopic = ICD-9 primary procedure 68.31, 68.41, or 68.51; abdominal/open = ICD-9 primary procedure 68.39, 68.49, or 68.9; and vaginal procedures are those with primary procedure code 68.59.  Cases with malignancy as defined by DRG 742 or 742 are excluded.
