Is robotic surgery feasible at a safety net hospital?

Robotic surgery offers potential advantages of improved ability to complete procedures using a minimally invasive approach, recovery, and clinical outcomes. It has been previously established that safety net hospitals are outliers for surgical complications. As such, the adoption of new technology may not achieve the same outcomes as other institutions. We hypothesized that, compared to laparoscopic and open surgeries, robotic surgeries have fewer post-operative Clavien-Dindo complications at our safety net hospital.

All robotic surgeries performed from 2017 to 2019 at a single, safety net hospital were reviewed. Cases were matched 1:3 to laparoscopic controls. Surgeries commonly performed open were additionally matched 1:3 to open counterparts. The primary outcome was Clavien-Dindo complications at 90 days post-operatively. Secondary outcomes included inadvertent enterotomy, conversion to open, operative duration, wound class, surgical site infection (SSI), surgical site occurrence (SSO), length of stay (LOS), reoperation, readmission, and recurrence.

A total of 160 robotic surgeries were included and matched to 480 laparoscopic surgeries and 108 open surgeries. Open surgeries were associated with greater risk of Clavien-Dindo complication (OR = 2.7, p = 0.040, 95% confidence interval 1.0-6.9) than either robotic or laparoscopic surgeries. Robotic cases had increased operative duration when compared to laparoscopic (p < 0.001) but not open cases (p = 0.093). No difference was seen in enterotomy, conversion to open, SSI, SSO, LOS, reoperation, readmission, or recurrence between robotic and laparoscopic, and robotic and open cases.

Robotic surgery is safe and feasible at a safety net hospital. Robotic and laparoscopic surgeries were associated with fewer Clavien-Dindo complications than open surgery, but no differences were seen between robotic and laparoscopic cases. Robotic surgery, compared to both laparoscopic and open surgery, had longer operative durations. Further studies are needed to assess the value of robotic as opposed to laparoscopic surgery in a safety net setting.
