Capturing da Vinci Metrics to Improve Quality, Efficiency and Education in Robotics Sonia L. Ramamoorthy, MD, FACS, FASCRS Professor of Surgery, Vice Chair of Quality Chief, Division of Colon and Rectal Surgery Sarah Stringfield, MD PGY-3 1 Perspective Critical investments within the surgical service line should be monitored over time for return on investment, observed vs expected outcomes, and utilization Prior to development of robotic surgery, few enterprises felt compelled to obtain metrics on surgical tools The robot presented a new challenges (paradigm?) not only in surgery but in administration, nursing, and supply chain 2 Initiative • Safety First • Create a body of peers to govern safe use of the da vinci robot • Provide the hospital with a methodology for credentialing robotic surgeons • Identify structured support teams • Structured Access • More surgeons meant more robotic time request • Overburdened OR • Physician utilization • OR time • Procedures • Financial metrics • Payer mix • Cost per case 3 Robotic Subcommittee (Perioperative Exec. ) • Chair and VC • All surgeon stakeholders • Administration • Nursing • Purchasing • Supply side • Industry support 4 Methods to obtain data at UCSD • All robotic operations performed at UCSD Medical Center were reviewed • August 2005-July 2016 • Data sources: • Electronic surgical scheduling system • ORSOS (2005-2013) • Epic (Oct 2013-present) • Da Vinci system • Hospital administrative databases • Robotic Surgery

2013, costs for OR supplies range from $1800- $6000 per case (excluding cardiac cases) • Costs for robotic supplies range from $925-$2100 per case • On average, robotic disposables account for 42.8% of supply costs in robotic cases • Living donor kidney 21% • Ureteral operations 70% 25 Results: Admissions costs • 2014-2015 admissions data for all robotic surgeries and their equivalent open operations • 22 types of operations across all specialties, selected by ICD9 code • ALOS for robotic cases 4.1 days compared to 5.9 days for their equivalent open operations • Range: -6.2 to +3.9 days • >5 day difference between robotic vs open • Total colectomy • Cardiac valve • CABG 26 Results: Admissions costs • Average cost/day for admission after robotic surgery 1.9x higher than open surgery • When factoring in shorter length of stay, robotic costs only 1.08x higher than open cases • Most cost-effective operations: • Total colectomy • Cardiac valve • CABG • Nephrectomy • Cholecystectomy • In 2015, prostatectomy, esophagectomy, and sacrocolpopexy were exclusively performed robotically 27 Education • Area of development for UCSD • Urology and Gyn following national guidelines • General Surgery still evolving • Residents interested • Faculty time challenge • Facilities state of the art • Integrating into residency • Progression from bedside to console surgeon • Progression from simple tasks to more complex • Demonstrated interest and skill • Challenge is integration into resident curriculum 28 Conclusions • Tracking our data has allowed us to fully “own” our program and make strategic decisions that benefits patients and the health system • A multidiscliplinary robotic subcommittee has been the key to • Monitoring safety, cost, and efficiency • Large increase in number and types of cases, across many specialties • Robotic trained faculty • Robotic trained residents 29 Future directions • Learning curve: surgeon specific vs OR staff • Residency Training • Conversion rates • Outcomes: transfusion, readmits, oncologic • Value undefined metrics- surgeon preference, ergonomics, single platform integration • Modelling for anticipated changes in future payment 30.
