Rates of Minimally Invasive Surgery After Introduction of Robotic-Assisted Surgery for Common General Surgery...

Area of Science:

• Surgical Innovation
• Health Services Research
• Minimally Invasive Surgery

Background:

• Minimally invasive surgery (MIS) offers benefits but is underutilized in many patient groups.
• Robotic-assisted surgery (RAS) can overcome limitations of traditional laparoscopic surgery.
• Increasing MIS rates is a key goal in modern surgical practice.

Purpose of the Study:

• To evaluate if the introduction of RAS increases MIS rates.
• To determine if these increases in MIS rates are consistent across various patient populations.
• To analyze the impact of RAS on common general surgery procedures.

Main Methods:

• Retrospective cohort study comparing MIS rates before and after RAS introduction.
• Utilized the PINC AI Healthcare Database (US all-payor discharge data).
• Generalized estimating equation regression models analyzed MIS trends in hospitals with and without RAS.

Main Results:

• Hospitals introducing RAS showed a significant increase in MIS rates compared to those that did not.
• The relative MIS rate increased from 1.08 to 1.15 post-RAS introduction in adopting hospitals.
• Increased MIS rates were observed across diverse patient demographics (age, sex, race, ethnicity, payor) in RAS-adopting hospitals.

Conclusions:

• Introduction of RAS is associated with increased rates of minimally invasive surgery.
• RAS adoption leads to greater MIS utilization across a wide spectrum of patient populations.
• Robotic-assisted surgery can help expand access to MIS procedures.
