And the problem with that is that it takes away RP from the physicians, and provides, in reality, a very little risk of carrying on, especially when used inside a very close ring of people. So I would suggest as follows:
1. Any treat used outside of the Madison rooms does have a risk for infection, from just mild ones to deadly ones; depending on how good the medics skills level, severity of the wound and type of room. Ie suturing an 80% wound in swamps would almost guarantee one for even most well-trained physicians, tending a bruised knee in a clean part of the streets would be virtually without risk for an even pretty new physician.
2. Those deadly infections have 100% chance of curing when treated and tended to in the Madison. make your choice, trust the back alley doctors to keep trying to keep you alive, or risk being exposed but alive. Or maybe seek mages to help, as sometimes neither of the above is a good option (they should get some spells around that if they don't have already).
3. Alert the Reeves/doctors when treat is used in Madison by a non-physician.
4. Ability to obtain IC rooms that are medical rooms, with varying quality, that adds a factor to a lower chance of infection. Creating those rooms should be done via plots, be paid for with high to exuberant amount of silver and leave traces of such room is organised. How many traces, what type, that would depend on rolls inside of the plot. Those places also require resupplying every X time, also done via a plot that has a chance to leave trails.
This would require careful balancing of course, but this should balance out the need for back alley physicians (starting from the high-risk cheap doctors, ending up with possibly Brotherhood ran hospital) with the need that normal players should only go and see an actual doctor when hurt. If they got something to hide, they could go back alley, but there is always a chance of contracting a potentially deadly infection.
Maybe even untended wounds, that do require tending, could have a chance of infecting too? Something for the pain-immune types
