Why Health Care is so complicated - part I

American health care has been widely talked about lately, not least because of proposals by the President and Congress to radically alter the current system. Some thoughts of mine on the subject follow - I expect this will be a multiple posting topic, as I'll continue to discuss it with others.

Terms

First, we need to define terms properly, which is much harder than it seems at first, and too seldom done. As Thomas Sowell says, for example:
The biggest of the big lies in the "health care" hype is that a lack of insurance means a lack of medical care. The second biggest lie is that health care and medical care are the same thing.

"Health care" is simple enough to define - any action, taken by an individual or another party, that affects the individual's health. If the definition sounds broad, it is; try thinking about something you do which never has any effect on your health.

"Medical care" is a bit tougher to define exactly. I think it works to define it as professional services rendered by doctors, nurses, any medical specialists(including but not limited to opthalmologists, oncologists, urologists, orthopedists, Lasik surgeons), paramedics, EMTs, first responders, and any similar person, performed generally with the expectation they will be paid for their services. (Some EMTs and first responders are volunteers, but this is uncommon and even in this case the EMS service/fire department will often bill for medical supplies and transport expenses.)

"Health insurance" is tougher yet because the term usually describes far more than is meant by "insurance" in any other area, namely the payment of a premium in exchange for the guarantee that a third party will pay a specified sum in the event of certain nonroutine losses/expenses. For reasons to be mentioned below, the U.S. tax code has given a strong incentive for routine expenses such as prescription drugs, annual physical checkups, and dental cleanings to be included under the rubric of "insurance", whereas for example car insurance does not commonly cover an oil change or a trip to the detail shop.

I think for my purposes of explanation, health insurance can be defined as any contractual system by which medical care for a given patient is directly paid for, in full or in part, by a third party(i.e. a party other than the medical professional and the patient). This can include systems like Medicare/Medicaid which are paid via tax revenues, employer-based coverage, or personally purchased policies; but the most important and relevant detail is the third-party payment system. The incentives for conduct of patient and doctor are much different when a third party is paying, as opposed to when the patient is paying out of pocket, and this is the fundamental source of administrative complication in modern medical care.

Next to come - a brief history of modern medical care.

New blog

I've started another blog, located here.

The new blog will be primarily focused on transportation and emergency response issues. I'll be posting more regularly on this blog, and focusing on general political commentary, from a conservative/libertarian/classical liberal POV. (Not that I'll apply one of those labels categorically to myself anytime soon, though.)

Happy reading, feel free to e-mail me with questions, gripes, etc.

Crash Data for Pittsburgh Highway Corridors

The Southwestern Pennsylvania Commission, I've just discovered, has a great deal of transportation data for our region. Among other things they have a Congestion Management Process which is supposed to collect data on highway congestion so that transportation planners know where it needs to be alleviated.

Of interest to an emergency responder, the SPC posts data on crash location and severity for the regional highway corridors. This I found to be particularly enlightening. For example, here(as a PDF) is the data for I-376 between the Turnpike and Downtown. Some points I thought were interesting:

  1. There are noticeably more crashes on Fridays and Saturdays, and I'm wondering why. Instinctively I'd say late night DUI drivers, but that's belied by the next point.

  2. The peak hours for crashes appear to be(in descending order) 14:00, 8:00, 13:00, 15:00, 16:00, and 2:00. Mid-afternoon doesn't seem to me a very accident-prone time, but if these data are correct that obviously needs to be rethought.

  3. 76% of crashes are in non-adverse conditions, which suggests, since Pittsburgh has 152 days annually with rain, snow, sleet, &c., that drivers are less competent or careful when the sun comes out.

  4. 43% of the collisions on 376 were rear-end collisions, and 40% were vehicle into a fixed object(barrier, sign post, and much more).
A couple of notes on the data:

The crash data are from PennDOT's CDART crash tracking system. These are "reportable" crashes only, defined by PennDOT and the SPC as "a traffic accident where someone was injured or where one of the vehicles had to be towed from the scene".

The "severity index" they have listed is a weighted average, with the following weights given to each crash type:
Fatal crashes = 12
Major injury crashes = 12
Moderate injury crashes = 3
Minor injury crashes = 2
Unknown injury crashes = 2
Property damage only crashes = 1
