The task of health care reform in 21st century America is to decrease per-capita cost of care and to increase the quality of care delivered to patients. It’s complicated. A famous Rand study concluded that Americans only receive 55% of the care that science dictates. Patients intuitively believe that more health care is always beneficial. Medicare reformers would like to do comparative effectiveness research so that CMS and private insurers could wind up paying only for therapy that actually works. Some estimate that 30% of all care delivered in the United States is waste. What some call waste, others label revenue, and Atul Gawande becomes famous for identifying waste/revenue in McAllen, Texas (http://bit.ly/ENlli).
Neuroscience tells us that the smartest human can only keep track of seven variables at one time, and physicians tell us that diagnosis and treatment of a complicated patient can involve as many as 100 such variables. Computers are good at cataloging, organizing, and retrieving information, but physicians are not yet routinely utilizing them at the point of care. Computers are also good at allowing us to analyze large data sets and learn from experience. Patients yearn for the warmth and caring of a doctor who really knows and cares about them. Behavioral economics pioneered by Amos Tversky and Daniel Kahneman taught us that human brains are designed with inherent biases that make us less than rational decision-makers. We now know that human physicians and patients suffer from biases such as Pygmalion complex, confirmation bias, focusing illusion, incorrectly weighing initial numbers, and being more impressed with single cases than conclusions based on large data sets (http://bit.ly/49q4Uy).Continue reading…
