The patients are tested, vaccinated, and sent out the door in a rush to maintain rapid turnover. Complicated patients that require treatment slows this process down, and decreases profits. T he days of doctors going on house calls are a thing of the past. It's not the doctor's fault, though. Monthly administrative meetings within most large clinics look at profit and loss statements just as though medicine were any other business.
Administrators address issues of income and expenses, just like any other corporation.
If patents on tests are profitable, that's what you do. If house calls aren't, then that's what you stop. The formula is maximum amount of money per hour versus least expenses per hour, with the least possible risk. You create treatment protocols that fit the needs of the clinic and not the patient. Then, you put the entire weight of the institution behind these protocols, and intimidate everyone who disagrees.
