“What We Did Not See First, our call for papers did not elicit any studies focused on the biotech, pharmaceutical, or medical industry sectors. While research in these sectors has been published in related journals ….. we found no publications in recent issues of Production and Operations Management and very few overall directly related to production and operations management. Given the growth and significance of the biotech, pharmaceutical, and medical industry sectors around the globe, it is imperative we begin to identify and address the unique production and operations management challenges faced by these industry sectors.” (p. 121)

“Industry studies is an observational science…..the systems we study involve companies and markets and institutions and their interactions ….. we must observe if we are to accurately understand and describe the remarkable complexity of it all.”
Reflections on Industry Studies
“We know that we need a microscope to see very small things …… Seeing large things, like industries, would be much simpler if we had a macroscope… Unfortunately we don't have a real macroscope.”
“Statistics is in fact our attempt at a macroscope but it is one that only functions erratically. It functions erratically because if we have the right overall picture, then the statistics can size it right for us, and tell us more about it, but if we don't have it right, the statistics won't tell us that we don't have it right and we can be very wrong.”
(Source: “Industry Studies: An Observational Science,” Speech by Dr. Ralph Gomory at the Annual Sloan Industry Center Meeting, Boston December 5, 2005.)

An Introduction to the Research Program:The Central Question
How can the development of care be linked with the delivery of care, globally and effectively?
“Effectively” = Right care at the right place at the right time at the right price

Health Care Supply Chain:A Value Based Perspective
“Health sector supply chain refers to the information, supplies, and finances involved with the acquisition and movement of goods and services from the supplier to the end user in order to enhance clinical outcomes while controlling costs.” (Burns 2006)

“Combine high-tech devices with low-tech care giving, while targeting the mind, body and spirit.”
“Most hospitals are warehouses for sick bodies…Hospitals should be healing environments built for patients.”

Medical Device Supply Chain: (Counterintuitive) Principles of Economics (Kruger 2005)
It is assumed implicitly that consumers of goods and services pay for the goods and services – as the price of a good rises, the demand falls.
Medical devices are largely free of this economic law – the demand for medical devices can be exceedingly inelastic (i.e., not depend on price).
Above-average profits are not sustainable, competition from new entrants drive down prices, narrowing margins and reducing profits.
Medical Devices do not appear to be subject to this general rule. Companies (e.g., Johnson & Johnson and Medtronic) have enjoyed sustained above average profits.
Growth in nearly every other industry sector slows as markets become mature and saturated.
In medical devices, growth is sustainable because it is driven by general demographic trends, the continued prevalence of diseases, and the near infinite capacity for absorbing medical technology within the practice of medicine.

Cardiovascular Disease (CVD) Care-CentricMedical Device Supply Chain
04/18/23
(Porter & Olmstead-Teisberg 2006)
Modes of business definition in healthcare are doctor centric, procedure centric, or institution centric, not patient centric.
Patient value in health care delivery….. can only be understood at the level of medical conditions…. Value is determined by how well a provider delivers care in each medical condition, not its overall breadth of services
The Focus on Medical Condition
Cardiovascular Disease (CVD) Care-CentricMedical Device Supply Chain
The relevant business in health care delivery is medical condition seen over full cycle of care.
For example, the business is congestive heart failure, not heart surgery, cardiology, angiography, or anesthesiology.
Business definition always involves a geographic component.

Cardiovascular Disease (CVD) Treatment Trends in the U.S.
(Source: World Health Organization)

World Health Organization (WHO) Statistics CVD is the commonest chronic illness in both developed and
developing countries, causing the most deaths and the greatest impact on morbidity.
Approximately one-third of the total deaths worldwide are cardiovascular in origin.
The CVD deaths amounted to numbers greater than those compared to the major infectious diseases (AIDS, TB and malaria).
Common perceptions about CVD are: It is a disease of the elderly, a disease of affluence, and even a pleasant way to die.

Major Causes of DeathIn Persons of All AgesIn Low and Middle-IncomeRegions

World Health Organization (WHO) Statistics (contd.)
Contrary to the conventional wisdom, 78% of the CVD deaths occurred not in the high income countries of the world but in the lower and middle income countries.
In sub-Saharan Africa, CVD is a major cause of death in the age range 15-60 years, killing more persons than infectious diseases, and the probability of death from a non-communicable disease is higher that in established market economies.
In India and China, socio-economic changes with individuals moving from a rural community into the cities have resulted in greater prosperity but at the cost of an increase in CVD related disabilities and deaths.
Cardiovascular Disease (CVD): Perceptions vs. Facts
04/18/23
WHO (2003, p. 70) reports “marked disparities in the quality of treatment can be seen in groups of different race, ethnicity, sex, and socioeconomic status. In essence, many patients who could benefit from treatment remain untreated, or inadequately treated,” highlighting the unserved and underserved global demand for CVD care.
WHO’s call for action: “In future, increased emphasis needs to be placed on the appropriate use of proven treatments for everyone with coronary heart disease or stroke.”

In closing ….
“Healthcare is a peculiar beast where in spite of all the new technology, costs keep going up all the time. That is a strange paradox. We are out to buck that trend. We cannot afford to let the masses be deprived of top class tertiary care.”
(Dr. Devi Prasad Shetty in “Narayan Hrudayalaya Heart Hospital: Cardiac Care for the Poor,” HBS Case April 2006)
