The cost effectiveness and advantages of Robotic Surgery

Cost-Effectiveness of Robotic Surgery

Entrepreneur and venture capitalist, Marc Andreesen recently indicated on Twitter that: “consumer costs rising most quickly (education, health care) have least tech innovation and least market competition.” Marc’s former partner in Netscape, the serial entrepreneur Jim Clark, founder of Healtheon, which later merged with and became known as WebMD has also been scathing about increased costs and poor innovation in health care. Clark’s vision for improving health care through technology innovation is perhaps best documented in the book The New New Thing by Michael Lewis.

Larry Page, co-founder and CEO of Google, spoke at TED about how advances of sharing medical records (anonymously) could potentially save 100,000 lives in the US alone per year. This is something the tech giants are working on. Dr. Eric Horvitz, who is the managing director of Microsoft Research and specializes in applying artificial intelligence in health care settings told Wired magazine: “Electronic health records [are] like large quarries where there’s lots of gold, and we’re just beginning to mine them.”

IBM’s Watson is also making terrific strides in advances of health related applications, and if it is not, it will soon be the world’s foremost diagnostician of cancer related ailments. Watson is being “trained” to sift through and stay up to date with all of the world’s high-quality published medical information; match it against patients’ symptoms, medical histories, and test results; and formulate both a diagnosis and a treatment plan.

Perhaps the area where tech is having the biggest impact in health is robotic surgery – in both innovation and costs, the two areas highlighted by Marc Andreesen.

There are approximately 25 companies providing electro-mechanical, computer driving surgical devices, or what has become known as Robotic Surgery. The companies ranging from major corporations such as Hitachi, to Hansen Medical Sensei, Mako Surgical, Mazor Robotics and smaller companies like RoboDoc, Endocontrol and Cyberheart, the EU have developed Robocast, or Dr. Robot, the brain surgeon.

Perhaps the leader in Robotic Surgery is Intuitive Surgical a NASDAQ listed company, the manufacturer of the da Vinci Surgical Systems.

At the end of financial year-end 2013, Intuitive Surgical had annual revenue of $2,265 billion and has set its sights on (See 2013 Investor Presentation): ‘long-term revenue potential for current target procedures as $7.2 billion:’ Broken down as follows:

  • Annual Instrument & Accessory Revenue $4.0 Billion
  • Annual System Revenue $1.9 Billion
  • Annual Service Revenue $1.3 Billion

This represents a whopping increase of almost 3.2 times revenue from year-end 2013. It’s not the purpose of this article to consider if that is a realistic target or not, but I certainly applaud the Intuitive Surgical management for setting it and for the impressive work they are doing improving surgical procedures. The point is to show the significant market potential of robotic surgery, and the impressive revenue that Intuitive Surgical is already securing.

The purpose is more to show that robotic surgery is advancing healthcare-technology, saving costs and potentially saving lives.

Robotic surgery

In a 2013 FDA survey, surgeons experienced with the Intuitive Surgical da Vinci system said their patients have less bleeding, fewer complications, much quicker recovery times and less time in the hospital – 24 hours on average. The surgeries were also often completed quicker and cleaner. Another interesting point; those who used the da Vinci robotic system to remove advanced cancer in the tonsils region of the throat said half of their patients were able to avoid chemotherapy.

Cost-effectiveness of Robotic Surgery

It may initially seem that robotic surgery would be more expensive than open surgery as it requires a large initial investment in the order of US$1 million to US$2 million and ongoing annual maintenance costs of approximately of US$250,000, costs that are not present in open surgery. Additionally, robotic surgery requires disposable or limited use instruments (eg, shears, needle drivers, graspers, forceps) with an average cost of approximately US$2,000 per instrument, which are replaced every 10 surgeriesversus the mostly reusable instruments in open surgery. However, reports have shown that the overall hospital costs were significantly lower for robotics compared with traditional surgery, and that, in some cases, the hospital could break even on their robotic investment after as few as 90 surgeries.

Not only is Robotic Surgery already cost-effective for insurance companies and hospitals and a better option for the patients recovery, but as robotic technology expands and improves, as is the case with most other technologies, costs will further decrease – it is only a matter of time before that is passed on to ‘consumers.’

Which to me goes a long way to answering Marc Andreesen’s concerns, although I still share his point that more competition is needed.

    Thanks for pointing out that the cost of health care for consumers are rising quickly. You also said that the area where tech is having the biggest impact in health is robotic surgery. I think it’s important to choose a surgeon that makes you feel comfortable and confident in your procedure.

  2. I really thought it was cool how the patients recovered better and experienced less bleeding and pain with the help of robotic surgery. I think this is a really great idea! Technology has advanced so far and has been such a great thing in today’s society. My grandpa has been considering robotic surgery. It seems like the benefits outweigh the risks and I will be sure to share this information with him. Thank you for sharing this.
