Good Point, Yves
Yves Smith discovers an interesting data point on just how badly our healthcare system fails as a market.
The issue has always been two thing, information asymmetry, and the need for immediate services, because when you have a pneumothorax, you are not going to compare prices.
Well her data point is the fact that a study has shown that the happier you are with with your doctor, the more likely you are to die:
There is an important study in the Archives for Internal Medicine last month, which escalates an ongoing row as to whether patient satisfaction is in any way correlated with positive medical outcomes. The answer is yes, and the correlation is negative.Here's hoping that Scalia, Thomas, Alito, and Roberts just love their doctor.
This finding is of critical importance, not just in understanding why American medicine is a hopeless, costly mess, but also as a window into how easy it is for buyers of complex services to be hoodwinked by their servicer provider, whether via the provider being incorrectly confident about his ability to do a good job or having nefarious intent.
Let’s deal with health care case first. The study in question was large scale, of 52,000 patients from 2000 to 2007. This summary comes from the Emergency Physicians blog (hat tip Julie W):Results of the study showed that patients who had the highest satisfaction ratings spent 9% more on health care and prescription medications than did patients who had the lowest satisfaction ratings. In addition, the most satisfied patients had a 26% greater risk of death compared to least satisfied patients. When patients in poor health were excluded, the risk of death for these highly-satisfied “healthy” patients increased to 44% more than their least-satisfied counterparts.
In commentary accompanying the article, Dr. Brenda Sirovich suggested that discretionary testing is likely the cause of both the increased costs and the increased mortality in highly satisfied patients. Patient perceptions, even if medically inappropriate, drive testing and treatment. Antibiotics are harmful in patients with viral infections, yet a substantial subset of patients are not satisfied without an antibiotic prescription for their colds. Large studies show no link between PSA screening and either overall survival or prostate cancer survival. However, any patient whose life has been “saved” by a PSA screen is often quite satisfied. In both scenarios, there is no perceived negative effect from treatment. Patients will recover from their colds with or without antibiotics. Patients likely would not have died from their prostate cancer even if it was left untreated.
