Do doctors charge too much

We all know that some doctors’ fees are excessive. I have blogged about this myself citing a neurosurgeon’s $117,000 charge for assisting on a case.

We also know that doctor bashing is a popular sport right now.

In an otherwise reasonable article about high-deductible health insurance on Vox.com, reporter Sarah Kliff’s second paragraph read as follows:

The bolded text was hyperlinked to a Washington Post piece about a study that showed wide variations in hospital charges for appendectomies in California. The study was not about physician fees. No matter how difficult the case was, no surgeon would ever have been paid $186,955 for performing an appendectomy.

Yesterday, I twice asked Ms. Kliff to please correct this grossly misleading paragraph. She acknowledged my request that evening, but as of 9 AM today, nothing had been changed.

Even if Ms. Kliff had correctly identified the hospitals as the culprits, using appendectomy as an example of why patients should shop for the lowest prices was a poor choice.

Nearly every patient with appendicitis does not know he has it until he has gone to an emergency room, seen an ED physician, and had some tests. I doubt most people in this situation would A) ask how much it’s going to cost to have an appendectomy and B) decide to go to another hospital for care. The fact is, hospitals are so secretive about their charges that a patient would be unable to comparison shop especially if the emergency department visit occurred outside of normal working hours.

Even trying to find out the charges for elective surgery remains difficult in 2015.

Physicians—particularly surgeons—have taken a lot of heat recently. We don’t need articles like this to inflame patients (and journalists) even more than they already are.

The article was just changed. The bolded mistaken passage was corrected, but the next sentence (underlined in red) remains the same. Still blaming those "really expensive doctors."

Variation is not causation

I made a rookie mistake in statistics of the “correlation is causation” genre by confusing variation for causation in the recent JAMA Surgery paper referred to in my last post. I contacted Dr. Timothy M. Pawlik, the lead author of the Johns Hopkins study, who said the following:

"The model is explaining and attributing variation in readmission and not attributing readmission itself to the different domains. The model suggested that only 2.8% of the variation in readmissions was attributable to surgeons. This is different than saying that only 2.8% were the fault of surgeons. A more accurate interpretation would be that only 2.8% of the variation seen in readmissions was attributable to provider level factors. The majority of the variation in readmission was due to patient factors."

He added that some of the 82.8% variation in readmissions attributable (note: attributable doesn’t mean it’s the patient’s fault) to the patient could be modified by better medically managing patients comorbidities or not operating on some of these patients.

That readmissions can be explained by a single domain or a single person is simplistic. Dr. Pawliks clarification confirms my original concern that attributing differences in patient outcomes solely to differences in technical quality of surgeons is probably inaccurate, statistically speaking.

Variation is not causation but variation is still a call to action. Regardless of who is to blame for unfavorable outcomes, surgery is a team sport. The incision is just as important as the community care. In this regard, I am certain that ProPublica and I are on the same side. Let’s work together so that we see the whole story behind the numbers.
