In the scheme of things, managing one business is like managing any other. Different nuances depending on the field, but a business is a business. Jim owning XYZ EMS is no different than Jim owning XYZ Car Maintenance without any mechanical experience.
Granted, I do think that EMS should be a public service. But emergency departments? I see costs that can be saved by insourcing.
Unfortunately medicine is not like any other business.
The fees you can charge are regulated. (In every civilized country in the world) Which means you need evidence (usually in the form of practice guidlines backed up by research) that what you are doing is worth paying for.
You cannot simply terminate the relationship very easily for delinquent payment.
In the event of the emergency room, there is a law that states you have to treat everyone regardless of their ability to pay. (A severely underfunded mandate in the US)
Does your business have to mow the lawn for people who cannot pay simply because their lawn needs cut?
Then there is standard of care, which means you cannot withold certain treatments because they do not make money. Conversely, you cannot perform procedures or "upsell" procedures that do make better money.
That stuff is even before customer service and satisfaction.
As well, your reimbursement for service is not static. You might not perform 3 bypasses a day in each OR because there are not that many people that need them. But you will still be paying those surgeons and OR teams whether they are working or not.
When you do not have a service a patient needs, you must refer them out to your competitor, you cannot offer them your list or "close enough."
Also, when you insource, the doctor no longer falls under the rules of a contractor. Which means the hospital needs to cover the cost of her mistakes or provide the malpractice insurance because the doctor is now an employee of the hospital.
Do you think it will save money to pay all of the doctors expenses, benefits, and salary with regulated reimbursement system?
What are you going to offer to attract quality help? To Whom?
Doctors are not laborers, they make independant decisons, they are involved in all aspects of operations, they are not all equally capable, and most of them are smarter than the average guy down at the shop.
You cannot run a hospital without doctors. Doctors know that. They are most likely going to demand a percentage. Because there is a finite number of each specialist, it gives such doctors considerable bargaining power.
If I produce 5x more income than my coworkers do you think I will settle for the same salary?
If I do procedures my coworkers do not do you think I will accept the same salary?
If I have more patients because of their satisfaction do you think I will accept the same salary?
I assure you, I can take my show on the road and my patients (your customers) with me. I can even set up a private practice that caters only to those patient needs, which makes me far more efficent than your ED.
Now I like working for a fixed salary, not a percentage, for a variety of reasons. But the moment you treat me unfairly, I am gone. Because I do have options and they only grow with time.
At this very moment, around the globe, some specialists are in such shortage with such a demand, they tell hospitals what they want. If the hospital cannot pay, then it cannot have them.
How long do you think your ED will be open when you can only hire dregs?
How will you compete with ED hiring board certified EMs when you cannot afford them?
