Poor socio-economic conditions, the presence of cavernous lesions, and a positive family history were poor prognostic factors. 83% of the patients treated at home (the very poor), died as did 86% of those treated in hospital (the very ill). Sanatorium R/ was well subsidized by particular initiatives (funds and charities), but a contribution was necessary. Sanatorium R/ also knew a considerable mortality rate of 55%, although not as high as the other 2 groups.
