NSQIP: Does it work?
• Cost effective? – Short answer: We don’t know. – Cost per adverse event is $12000 in Canada
• 10-15 fewer adverse events pays for investment – If adverse events decrease, cost avoidance could be
seen – Guillamondequi et al (2008-2010):
• 2 million USD per 10,000 General Surgery cases – Unanswered question
![Page 59: Complications in Colorectal Surgery - BC Cancer€¦ · • Only 54% of patients with complications had chemotherapy vs 70% (p](https://reader035.vdocuments.net/reader035/viewer/2022070715/5ed76c6c2a2f0d6edb31efd4/html5/thumbnails/59.jpg)

Colorectal Cancer: Complications
Doctors and scientists are now being asked to accept a new understanding of what great medicine requires. It is not just the focus of an individual artisan-specialist, however skilled and caring. And it is not just the discovery of a new drug or operation, however effective it may seem in an isolated trial. Great medicine requires the innovation of entire packages of care—with medicines and technologies and clinicians designed to fit together seamlessly, monitored carefully, adjusted perpetually, and shown to produce ever better service and results for people at the lowest possible cost for society.
