This is an interesting article, Blue Dog. I think challenging the assumptions inherent to "healthcare reform" (I hate that term -- so ambiguous and cliche) will be critical to developing real solutions for a sustainable healthcare system.
Unfortuntely, I think this article also rests upon some very shaky assumptions. For example, the thought that primary care may cost more than the ED is a bit questionable.
"People also tend to think ER visits cost far more than primary care, but even this is
disputable. In fact, the marginal cost of treating less acute patients in the ER is lower than paying off-hours primary care doctors, as ERs are already open 24/7 to handle life-threatening emergencies."
I agree that the marginal cost of an off-hours PCP visit would probably cost more than an ED visit at 2 am. However, this article assumes that a person would either go to an ER or go to an off-hours primary care doctor with whatever ails them, but is this true? If we provided the right incentives (higher deductibles, copays, etc. -- all after fair layperson review), wouldn't people choose to wait until regular hours to go to a primary care doctor? And, if they really did need to see a doctor at 2 am, wouldn't that be considered urgent? I think we're comparing apples and oranges here...
In this sense, we should be comparing ED rates to regular hours primary care rates. Speaking from the experience of a Health Econ intern working for a Managed Care Organization studying ED diversion rates in an RCT, one can easily show the ROI by diverting non-urgent cases from an ED to a PCP or nurse hotline. The embedded NEJM article says otherwise, but, again, remember that we're comparing apples and oranges. The marginal cost of an additional PCP visit during regular hours is phenomenally low. This may stem from the difference in ED and PCP approaches; ED's tend to be more diagnostic/procedural oriented (more costly), whereas PCP's tend to use more H&P (very cheap). (For obvious compliance reasons, I can't post my study here. You can either trust me on this one or not -- I don't blame you either way. I suspect I'll get torn apart for this one... fair enough...)
Also, interestingly enough, the embedded JAMA article when you click "uninsured" contradicts the Slate writer's point on ED v. PCP marginal costs.
Available data support the statement that care in the ED is more expensive than office-based care when appropriate, but this is true for all ED users, insured and uninsured.
Furthermore, I think the Slate article may have misinterpreted the intent of the JAMA article regarding the uninsured. The JAMA article was a database review that noticed many journal articles rest upon the assumption that the uninsured are crowding out the insured in the ED. In addition, the authors noted that there is not sufficient data to substantiate such assumptions. In other words, the JAMA article pointed out an absence of evidence. As my statistics professor would say, "absence of evidence IS NOT evidence of absence." We can disprove a null hypothesis, but definitively proving the alternate hpyothesis is pretty darn tough.
Please don't get me wrong -- this is a great article. I think we're on the right track. Challenging assumptions is the life blood of great science and medicine. Without articles like this, forcing us to provide evidence to substantiate our claims, we will not find the complex solutions for improving healthcare. I take issue with a few of the assumptions inherent to the author's argument, but the article is well-written, thoughtful, insightful, and I thoroughly enjoyed reading it! Thanks, Blue Dog!
