Lowering health care costs thanks to technology
This last assignment was particularly hard for me. I don’t know what people may think, but ten ways to reduce health care costs are a LOT of creative ways to use technology to solve medical issues. This is why many of the top researchers in health technologies occupy years in their fields trying to come up with an answer to this question: how can technology help us reduce healthcare costs?
Efficient Technologies
The first thing we must consider when creating new technologies to reduce health care costs is if their cost is low enough to significantly help lowering the price of medical help. Many technologies have proven to be extremely helpful in curing many diseases, even those deemed untreatable a few years ago, but the high cost of manufacturing them and the high demand they have provokes a great rise in healthcare costs. Therefore, we must engineer solutions not only to solve problems, but also to do so in a cost and energy-efficient manner. This way we will be creating technologies that better the quality of medical treatments sustainably and inexpensively.
Reducing the need for healthcare
This may seem like a trivial point, but in theory if we were all healthy there would be no demand for medical care. This doesn’t mean that we must be naïve and assume that everyone will always be healthy and well-off in society through plain diet and exercise (although this is essential considering the rising percentages of obesity and diabetes in the US), but rather that preventive measures can go a long way. An article published in the New England Journal of Medicine actually calls for health promotion and disease prevention (since preventable diseases, according to the authors, account for “approximately 70 percent of the burden of illness and the associated costs”[1], which is backed by Healthy People 2000) arguing that “reducing the need and demand for medical services is a positive solution, one that will bring better health for the individual, and that will ultimately lower medical costs”[1].A good way to implement this plan would be with online medical and support databases, to give people access to medical information to see how they can make a difference by improving their lifestyle and personal health.
Health Information Technology Databases
Along the same lines as the previous point, health record infrastructure is one of the biggest challenges modern medicine faces. According to one source “Today's health care system is widely fragmented and hugely inefficient. Patients may be treated at multiple locations by multiple doctors who keep multiple paper records and fill out multiple paper forms seeking reimbursement from multiple insurance carriers. These inefficiencies not only lead to higher costs, they also result in poorer quality health care”[2]. Therefore, they propose a system called “telehealth” which, could “remotely monitor patients, facilitate collaboration between medical professionals, exchange medical data and images, and instantaneously provide efficient emergency service to remote areas”[2]. This way, the cost and hassle of going to the hospital (especially for chronically or disabled patients) is extinguished because there is no urgent need to make the trip to the doctor’s office.
Another interesting piece of writing concerning HIT Databases talked about “e-prescribing” and the approval of electronic health records, as well as the solution that HIT would provide “as the hardware and software that process information pertinent to storing, retrieving, sharing, and use of healthcare knowledge. This knowledge is then used for more effective communication among healthcare professionals, and for better decision-making. This includes maintaining health records online, so doctors can more easily access information when the need arises”[3].
Providing clean water
One of the most basic and overlooked ways to help better the general population’s health is to provide access to clean water. Although this is taken for granted in the United States, many nations across the globe still don’t have access to clean drinking water, which can greatly increase our life expectancy. Research by the World Health Organization shows that, with the adequate water distribution infrastructure, "an important share of the total burden of disease worldwide—around 10%—could be prevented by improvements related to drinking-water, sanitation, hygiene and water resource management”[4]. This would be a substantial change for the roughly 2.6 billion people[5] who don’t have access to this basic human need, greatly impacting global human health.
Outsourcing medical tests
With the digitization of information, outsourcing medical tests might prove to be a great solution to decrease the overall price of health care. According to one website “A number of hospitals in the US and UK are outsourcing laboratory and diagnostic tests to India as it costs about 70 to 80 per cent less to conduct them here. At the moment, this is generally limited to highly-specialized tests but experts say outsourcing of laboratory testing and diagnostic services is set to become big business in India”[6]. Another article further promoted outsourcing as a way of being competitive in the medical industry, encouraging companies to outsource the manufacture of entire medical devices[7].
Lack of competition in the high-tech medical realm
One of the biggest problems in high-tech medicine is the degree of specialization that each company must have in its specific field. This means that many corporations don’t have any competition in their area of medical technology and can therefore state their price for new devices and treatments, as there is no alternative. Take for example, the University of Maryland owns a da Vinci robot, which doctors use to perform remote minimally invasive surgery feet away from the operating table. This piece of equipment is worth roughly "$1.5 million, and every time it is used in the operating room, some $2,000 worth of parts must be replaced (for safety reasons). It takes a surgeon 12 to 18 months to learn how to use the machine, and a da Vinci operation usually takes longer than a hands-on procedure. Consequently, a University of Maryland study estimates that the robot adds about $8,000 to the price of bypass surgery"[15] . But the company who developed it (Intuitive Surgical) is the only one that produces these robots that allow quick recovery, minimally invasive surgery and access to many tight spots (useful for example in prostate surgery) commercially. Therefore there are no incentives for this firm to try to produce the machine more inexpensively, as it makes a much higher profit selling its products with enormous prices. If there was a big push towards science and research, more businesses in this field would arise that might develop similar products at more affordable prices, thus creating a healthy competition that would help lower and regulate the prices of medical technology.
Getting personal and user-friendly
This point was extremely reinforced in the “Grand Engineering Challenges” and "Healthy People 2010" reports as one of the most important goals to achieve in order to make healthcare affordable. Although it might seem unintuitive, personalizing healthcare could in fact prove to be worthwhile in the long run. Having more specific medications, tests and background information could break the “one-size-fits-all” medical perspective that exists nowadays and model a system where we begin tailoring each patient’s necessities to optimize the treatment of illnesses. Another way to encourage this would be to have user-friendly medical technology, that allows simple and clear access to medical information; thus, eliminating the obscurity of medicine and allowing people to make informed and wise choices.
Ingenious ways of using current technology
This would be one of the greatest ways to reduce healthcare costs: adapting existing technologies (and developing new ones) to accessible and affordable equipment. One company has been working on digestible chips that allow doctors to remotely monitor patients and control medication dosages, taking advantage of an already-existing wireless infrastructure and conventional laptop computers[8]. However, these chips are very expensive and still in their experimental stages, which is why insurance companies still don’t cover their use and only people on very high budgets can afford them.
Another interesting research project is being undertaken at UC Berkeley, where a group of researchers have invented a “cellscope”, a device that allows high-resolution imaging using powerful LEDs and off-the-shelf cell-phones. This invention could potentially replace regular microscopes in developing countries and remote locations thanks to its high-resolution images and affordability[9].
New research for treatment of diseases
This is how today's common vaccines started hundreds of years ago. We must invest wisely in promising experimental treatments such as stem cell research or genetic therapy, which could provide solutions to many illnesses in the future, and play an important role in disease prevention. Although it might be expensive at the beginning, in the years to come the benefits of these experimental therapies might be extremely high.

The slinky effect
Although during inauguration the Obama administration pledged, “we will restore science to its rightful place, and wield technology's wonders to raise health care's quality and lower its cost”[10] many people are skeptical about whether technology will in fact lower the cost of health care. It’s obvious that technological advances have greatly helped in advancing medicine, but they may also be responsible for the skyrocketing prices of health care in the US. According to the National Coalition on Health Care, the expenditure on national health “is expected to reach $2.5 trillion in 2009, accounting for 17.6 percent of the gross domestic product (GDP). By 2018, national health care expenditures are expected to reach $4.4 trillion—more than double 2007 spending”[11] and the problem is that the GDP is not growing at the same rate (“average annual growth in national health spending is projected to be 6.2 percent—2.1 percentage points faster than average annual growth in gross domestic product (GDP)”[12]). Many blame technology for this rise in the national expenditure on health care, which nonetheless has enabled a much higher quality in medical services.
In fact, it seems as though it is not the quantity of health care but the value and efficiency of medical help that matters. Many nations across the world spend much less on healthcare (in percentage of GDP) and yet have higher life expectancies and lower infant mortality rates. For example, life expectancy in the US is roughly 78.1 years with about 17% of the GDP being spent on health-care, while Japan spends less than half of this percentage and has an average life expectancy at birth of 82.1 years[13].
One article reasoned, “because the spread of new technologies is relatively unrestrained in the United States, many of these technologies are used to a greater extent than in other nations, and the United States thereby incurs higher health care costs”. However I believe there are ways to prevent this. Quoting Scientific American “Providing the best and most affordable care will depend on finding and using the technology that makes the most sense”[14] at the risk of increasing the cost if we do not do so. It is the only solution to the pressing issue of rising health care costs.
