Versius Robotic Surgery in the NHS: A Multi-Specialty Retrospective Study

Primary outcomes

• Procedure related complication rates [Within 30 days and 12 months after surgery]: Rate of total procedure related complications within 30 days and up to 12 months following surgery

Secondary outcomes

• Conversion rate [Up to completion of surgery]: Proportion of surgical procedures requiring unplanned conversion to conventional laparoscopic or open surgery.
• Operative time [Up to completion of surgery]: Surgical time from skin incision to skin closure

Revision surgery is defined as any subsequent surgical procedure required as a result of the index surgical procedure or the underlying condition for which the index surgical procedure was performed.
• Rate of pre-defined index procedure specific complications [Within 30 days and 12 months after surgery]: Percentage of participants who experience one or more pre-defined procedure-specific complications related to the index surgical procedure
