Part 1: Can Robotics Improve Surgical Outcomes?: A Study on Laparoscopic Hysterectomy

In Part 1, the authors discuss why this study is important, including the impact of cost effectiveness and how their study makes a significant contribution to the knowledge base.

That’s what one team of researchers sought to determine as they explored its use in the case of laparoscopic hysterectomy. Despite the clinical benefits of laparoscopic hysterectomy, the technical challenges associated with this procedure cause its use to lag well behind conventional laparotomy. Robot-assisted laparoscopy emerged on the scene as a way to assist surgeons in overcoming the technical challenges, but little is known about its comparative clinical effectiveness and economic impact.

We’ve invited members of the research team who explored this question to share what they have learned with us.

Objective: To compare clinical and economic outcomes (hospital costs) in women undergoing laparoscopic hysterectomy
performed with and without robotic assistance in inpatient and outpatient settings.
Methods: Using the Premier hospital database, we identified women .18 years of age with a record of minimally invasive
hysterectomy performed in 2007 to 2008. Univariable and multivariable analyses examined the association between robotassisted
hysterectomy and adverse events, hospital costs, surgery time, and length of stay.
Results: Of 36 188 patient records analyzed from 358 hospitals, 95% (n 5 34 527) of laparoscopic hysterectomies were performed
without robotic assistance. Inpatient and outpatient settings did not differ substantively in frequency of adverse events.
For cardiac, neurologic, wound, and vascular complications, frequencies were ,1% for robot and non-robot procedures. In
inpatient and outpatient settings alike, use of robotic assistance was consistently associated with statistically significant,
higher per-patient average hospital costs. Inpatient procedures with and without robotic assistance cost $9640 (95% confidence
interval [CI] 5 $9621, $9659) versus $6973 (95% CI 5 $6959, $6987), respectively. Outpatient procedures with
and without robotic assistance cost $7920 (95% CI 5 $7898, $7942) versus $5949 (95% CI 5 $5932, $5966), respectively.
Inpatient surgery times were significantly longer for robot-assisted procedures, 3.22 hours (95% CI 5 3.21, 3.23) compared
with non-robot procedures at 2.82 hours (95% CI 5 2.81, 2.83). Similarly, outpatient surgery times with robot averaged 2.99
hours (95% CI 5 2.98, 3.00) versus 2.46 hours (2.45, 2.47) for non-robot procedures.
Conclusion: Our findings reveal little clinical differences in perioperative and postoperative events. This, coupled with the
increased per-case hospital cost of the robot, suggests that further investigation is warranted when considering this technology
for routine laparoscopic hysterectomies.
