Healthcare cooperatives formed by patients, hiring medical practitioners to take care of them and possibly for outside persons as well.
I wonder how is this going? I have limited knowledge on that sort of efforts but it's a topic that interests me.
I know of some cases of doctors self organising to provide their services. The longevity of the projects Ι have heard of varies. One of them did last for a few years, but I remember the last dentist left told me they got afraid of having their license to practice revoked.
Also in Chiapas the Zapatistas have been doing tremendous work on it. If I remember correctly from last time I checked, they mainly relied on local traditional medicines and had help some conventional doctors. I understand that this example is a totally different to the situation you are describing but I think it is slightly relevant in the broader sense of autonomous health services.
