how malpractice liabilities are estimated. In the end, the base calculation comes down to a series of factors, any of which could send the calculation in a different direction. (I'm familiar with how malpractice liabilities are calculated for hospitals and assume the physician estimates are similar.) It might give you a reference point for reading the reports.
I'm somewhat skeptical of the influence of defensive medicine myself,at least in the form of extra tests, having been a hospital bean counter at various levels for a long time. I tend to look at these things by asking what the institution would save if 'x' number of procedures were reduced. If a hospital has only one MRI, reducing scans by 5% might well have only a small impact, in savings of disposable materials etc. In order to make a real impact, you need to reduce staffing generally, and it will take a significant reduction to make a single rad tech unnecessary, if that's even possible. Hospitals have a huge amount of 'fixed' costs which don't change based on the number of patients or tests.
Of course, there are areas where I think there's a 'build it and we'll use it' phenomenom in place, particularly in specialized procedures. From what I've read, there are far more cardiac cath labs pro rata in the US than anywhere else. US patients diagnosed with cardiac arrest have a much much higher rate of caths, angioplasty and CABGs within the first year of having had a heart event. (Those procedures are all nicely covered by the Medicare program and many of the recipients are the elderly.)That's probably not a coincidence! I have a fond memory of a meeting which I attended years ago in which our new director of neurosurgery tried to convince us to buy him a $3.5 million toy called the gamma knife. (Among other things he told us was that Prince Ranier had bought one for a hospital in Monaco. The appeal of it was that the procedure was at that point actually being reimbursed by Medicare at the very high rate for invasive neurosurgery, because the technology was so new. We declined and he quit over it.) That type of technology shopping drives healthcare costs up quite a bit.
You might find this website interesting. It's for the Organization for Economic Co-operation and Developmentwhich collects economic data from Europe and the Americas primarily,
and has a healthcare section at:
http://www.oecd.org/document/22/0,2340,en_2649_33929_1935190_1_1_1_1,00.htmlThey sell statistical data sets but also make several dozen of the charts available as a 'teaser'.
Back to malpractice. The one lawsuit area which I believe might benefit from some sort of oversight, altho I can't tell you what that exactly would be, is in OBG. I live in NYC; NYS allows suits to be brought against OBGs until the child turns 18.I'll go out on a limb here, and opine that if the child's problems shows up later than say age 10, I doubt the problem was caused during delivery.
(This relates to my comment above abt familiarizing yourself with how malpractice liabilities are derived. One has to build in to the calculation an estimate of future claims, and with 18 years in the future to worry about, I assume that good-sized cushions get built into the premium costs.) There's a large sympathy factor at play in those cases and I believe that jurors sometimes award a 'pain & suffering' windfall because of it. One of the places where I worked attracted patients from all boroughs, and plaintiffs have the right to sue either in Manhattan where the hospital is in this case, or in the borough where they lived. If the patient was from the Bronx, the rule of thumb was to try very hard to settle because jurors there historically were quite liberal with the OBG pain & suffering awards and very plaintiff friendly.
