Decision Making Model on Stroke Prevention: Warfarin or not
Beste Kucukyazici showed the study of stroke patient data to see if a decision model could be derived to systematically decide on the commencing of warfarin treatment for stroke patient and its intensity. Now my question is: will OR decision models take a bigger and bigger foothold in the future of medical arena as we start to gather more useful patient data in well-planned studies? Medical doctors tend to argue that each patient has a different case, and need to be examined on an individual basis. However, if a model such as Kucukyazici’s can prove the accuracy of its decision given real patient data, then it would probably start to weaken the doctor’s argument and favour a more systematic approach. At least, such models might help reduce the complexity of doctor’s decision making process, or even reduce chances for human errors in diagnosis.
Atrial fibrillation, which is a common arrhythmia particularly common among the elderly, is one of the major independent risk factors of stroke. Several randomized control trials have shown that long-term antithrombotic therapy with warfarin significantly reduces the risk of stroke, however, it also increases the risk of suffering a major bleed. Given the potential benefits and risks of warfarin treatment, the decisions that need to be made by the clinicians are two-fold: (i) whether to start the therapy, and (ii) the intensity of warfarin use. The objective of this study is to develop an analytical framework for designing the optimal antithrombotic therapy with a patient-centered approach. The approach seeks to create a rational framework for evaluating these complex medical decisions by incorporation of complex probabilistic data into informed decision making, the identification of factors influencing such decisions and permitting explicit quantitative comparison of the benefits and risks of different therapies.

ORAHS 2008 in Toronto Canada
Mike Carter on New Challenges for OR Applications in Health Care
Professor Carter is one of the Canadian leading experts in healthcare and operations research, with over 17 years of experience in OR applications in healthcare. He currently leads the Centre for Research in Healthcare Engineering, Mechanical and Industrial Engineering, University of Toronto. Click here for more information on Professor Mike Carter.
Mike has been very kind to allow me to publish his talk here on ThinkOR.org. Here are some key points to take away:
- Healthcare is North America's single largest industry; Canada spent $142 billion CDN in 2005; US spent $2 trillion.
- Canada's per-capita spending ($3,326 USD) was half of US ($6,401 USD), and this is how it's been growing:
- US & Canada are about the same in terms of quality of health care, access, efficiency , and equity (based on the Commonwealth Fund 2004 International Health Policy Survey)
- A new way of looking at the healthcare system's stakeholders (no wonder it's difficult to make decisions in a hospital):
- Challenges in healthcare system can be viewed as operations research challenges:
- Patient flow - supply chain
- Surgical wait list - better scheduling
- Infectious diseases - logistics
- Health human resources - forecasting
Mike also demonstrated the application of O.R. techniques in his own practice:
- Ontario Wait List Management
- Colorectal cancer screening
- Cancer treatment centre locations
- Health Human Resource Modelling
Thank you Mike for allowing me to write about your talk. It was delightful to see OR in action in the Canadian healthcare. We look forward to seeing the 30% potential waste of money spent in healthcare to shrink fast.

Edelman Award: The Oscar of O.R.
Traffic on the railway nearly doubled between 1970 and 2006, but its timetable had not changed, leading to commuting problems...
Restructuring increased the percentage of trains arriving within three minutes of schedule from 84.8 percent in 2006 to 87 percent in 2007, while the number of passengers increased 2 percent in the first six months of 2007.
Profit, meanwhile, rose $60 million and the changes made additional capacity available...

Making Decisions at Procter & Gamble: O.R.
- which brand should be used for new products
- how to choose suppliers to procure and source materials
- how to use forecasting to deal with the factors impacting international trade and finance
- how much inventory to store and where
- how to keep and attract workforce talents for the company
It is obvious that OR applications in businesses can make a company very powerful, but it takes the OR talents who can talk business to do it. To quote Brenda Dietrich, an IBM fellow at IBM’s Watson Research Center:
There’s a gap between the math professionals and the nonmath executives in
many companies. The companies who have people who can walk into a business meeting and tell executives how to use OR tools are the ones who’ve got the edge. Deployment is no longer done just by the math people; analytics has become much more usable by a broader set of people within an organization.
