One of our IM staff is involved in this type of practice (I'm PGY3). He keeps very finacially satisfied in our midwest city (not Chicago).
Sophiejane's post above gives a good approximation of what I've heard about in these groups. As it was explained to me, there are of course variations on the theme. Some examples:
1. In my staff's practice, they actually admit. So they are on call and will meet the patient in the ED and follow them in the hospital. Some groups do not offer this.
2. Patients in his model pay $5000 for the year, but have to have supplemental catastrophic insurance. Otherwise one ICU stay would wipe out your practice. Peds pay less ($2000?) and are actually a loss due to the cost of visits and vaccines. Other payment schemes exist.
3. Routine labs are deducted from the annual fee, as are aforementioned shots. Many value-added services are included as well, such as routine baseline CXR's and treadmills. MRI's and CT scans are extra.
As far as patient population, I'm sure it varies, but this group sees middle-aged middle-class men primarily. Many are self-employed and found this to be cost-effective compared to full insurance. Many simply want to get what they pay for. I think very few patients would be the type to page you from the grocery store and ask which kind of butter they should buy.
As far as compensation, they do very well - even part-time it would exceed most full-time PCP's. Besides their payment schedule, this is also due to having virtually no support staff. They have no nurses. They have no billing department. The patient meets the physician, vitals are taken by the physician, exam is done by physician, and billing has been sorted out beforehand. They keep a higher percentage of the revenue generated than do other PCPs. (And at 200-400 patient load, you do the math....)
As far as benefits, there are many. My favorite is that you can appropriate more resources than you may traditionally, since labs and tests do not need to be justifiable to insurance companies. Of course I am not encouraging wasteful medical practice. But we understand that preventative guidelines are influenced by the cost, as well as disease prevalence and other factors. By taking cost out of the equation, we can reevaluate our goals. In Japan, EGD's are done to screen for gastric ca. Gastric ca is just as fatal here; we just do not screen because the lower incidence here makes the cost outweigh the benifit. This is an example of how one could be free to practice outside normal parameters (assuming you do EGD's
)
