Robot-assisted versus open radical prostatectomy utilization in hospitals offering robotics

Area of Science:

• Urology
• Surgical Oncology
• Health Services Research

Background:

• Prostate cancer is a leading cause of death in American men.
• Treatment options vary, but their utilization patterns are not fully understood.

Purpose of the Study:

• To identify factors associated with the utilization of robot-assisted radical prostatectomy (RARP) versus open radical prostatectomy (ORP).
• To analyze patient and hospital characteristics influencing surgical treatment choices for non-metastatic prostate cancer.

Main Methods:

• Observational study using linked administrative and hospital survey data (2009-2011).
• Included 36,694 non-metastatic prostate cancer patients in California, Florida, and New York.
• Hierarchical regression models with fixed effects for hospital and physician clustering were used.

Main Results:

• Robot-assisted radical prostatectomy (RARP) was used in 77.13% of cases, while open radical prostatectomy (ORP) was used in 22.87%.
• Lower RARP utilization was observed in African American patients, those with Medicare, Medicaid, or self-pay insurance, and patients in Florida or at teaching hospitals.
• RARP was more expensive than ORP ($13,614.83 vs. $12,167.44).

Conclusions:

• Patient demographics, insurance status, geographic location, and hospital type are significantly associated with the choice between RARP and ORP.
• These findings highlight disparities in the adoption of robotic surgery for prostate cancer treatment.
