The federal government is about to spend big on health-care IT. Too bad the medical industry has a vested interest in inefficiency.
Technology is once again being touted as a cure-all, this time for what ails the American health-care industry. The Obama administration's $787 billion stimulus plan includes $19 billion for health-care IT spending that provides incentives for doctors and hospitals to adopt electronic health records. Starting in 2011, stimulus funds will provide additional Medicare and Medicaid reimbursements for health-care providers using such systems.
These federal funding programs assume that the critical hurdle to widespread adoption of electronic medical records is cost. Indeed, hospitals surveyed in a study published last year in the Journal of the American Medical Association reported cost as the major barrier. Yet compared with other businesses, the health-care industry has been unmoved by the logic of lowering costs to increase profits. The truth is that these folks could have digitized the whole industry ages ago. The technology has been around for a long time: Wall Street began phasing out physical stock certificates over 35 years ago. Even the cash-strapped airline industry has gone ticketless, removing huge labor and overhead costs. These industries started using electronic records because they believed it would save money. The health-care industry simply has not followed suit.
The reason lies neither with cost nor with inadequate technology.
Rather, the health-care industry's reluctance to digitize its records
is rooted in a desire to keep medicine's lucrative business model
hidden. Dangling $19 billion in front of a $2.4 trillion industry is
not nearly enough to get it to reveal the financial secrets that
electronic health records are likely to uncover--and upon which its
huge profits depend. In those medical records lie the ugly truth about
the business of medicine: sickness is profitable. The greater the
number of treatments, procedures, and hospital stays, the larger the
profit. There is little incentive for doctors and hospitals to identify
or reduce wasteful spending in medicine.
The amount of unnecessary spending is huge. In a project that analyzed 4,000 hospitals, the Dartmouth College Institute for Health Policy and Clinical Practice estimated that eliminating 30 percent of Medicare spending would not change either access to health care or the quality of the care itself. The Congressional Budget Office then suggested that $700 billion of the approximately $2.3 trillion spent on health care in 2008 was wasted on treatments that did not improve health outcomes. This excessive spending has kept the entire health-care industry growing faster than the population, and faster than inflation, for decades.
While electronic medical records do have sizable up-front costs, they also have the potential to save big, in part by streamlining administrative costs. According to a 2003 article by Dr. Steffie Woolhandler in the New England Journal of Medicine, administration accounts for 31 percent of expenses in the U.S. health-care industry, or more than $500 billion per year. (To put that in perspective, Google has spent well under 10 percent of that on all its R&D.) Richard Hillestad of the Rand Corporation wrote in Health Affairs, in 2005, that health-care information technology could save physicians' offices and hospitals more than $500 billion over 15 years thanks to improvements in safety and efficiency.
Electronic medical records would make it much easier to conduct the studies needed to track down this wasteful spending. According to one estimate, only about 4 percent of U.S. hospitals use comprehensive electronic record systems; most rely on paper records. As a result, analyzing the effectiveness of specific treatments--for example, spinal-fusion surgery versus physical therapy for back pain caused by a herniated disc--is unnecessarily expensive and time consuming. Physicians must compile data for a significant number of patients undergoing each treatment and correlate that information with each patient's outcome.
Using electronic health records, in combination with data mining and search technology, would make this kind of analysis much easier. Patients who fit specific criteria could be identified and tracked automatically, for example. Researchers would be able to analyze larger numbers of patients and a wider variety of treatments. With easy access to this kind of information, wasteful spending could be identified more readily, allowing payers, whether Medicare or private insurers, to stop reimbursing for expensive but unnecessary tests and procedures.
An even bigger threat to the sickness industry's business model is that by allowing automated tracking of patients over time, electronic health records would set the stage for early detection and preventive medicine. Currently, the entire industry is organized around treating sickness, rather than keeping people healthy in the first place. Three-quarters of health-care spending is devoted to chronic care, but the National Cancer Institute and the Centers for Disease Control and Prevention allot just 12 percent of their budgets to research on early detection. Moreover, the payment system is structured around reimbursement for treatment rather than prevention.
With widespread use of electronic health records, it would be easier to expand preventive medicine, not only by educating patients about lifestyle changes but also by conducting mass screenings. A recent American Cancer Society study concludes that prevention, early detection, and better treatment decreased cancer death rates between 1990 and 2005 by 19 percent for men and 11 percent for women. I would like to see funding for technologies that could ultimately improve early detection. Studies are now being launched on CT scans that can evaluate a patient's heart in less than one heartbeat. They produce finer resolution than existing technologies and return fewer false positives. These tests cost $1,000 now, but within five years, thanks to expected advances in computing power, we should see a $200 CT scan to detect heart disease before a heart attack.
The ability to detect cancer early enough and cheaply enough for effective treatment would prove much more cost effective than the current approach, which involves spending hundreds of thousands of dollars to extend the life of a cancer patient for a few months--generally, with low quality of life.
As valuable as electronic health records are for streamlining costs, their biggest contribution will lie in moving medicine toward early detection. Let's hope that the adoption of this screening technology is not postponed as long as electronic medical records have been, in a misplaced desire to protect the lucrative status quo. Like all good technology, it's probably going to get off the ground on the grassroots level. Expect your local Walgreens to promote these tests sooner than your doctor does.
