Rob: thanks for your question. I don't think there is a one-size-fits-all answer as context will play a key role. These informal entrepreneurs currently exist, provide care and get paid by fees collected from users which as we know has important equity implications. One of the mechanisms being tested by WHP is having formal practitioners paying commisions for referrals while training and support is subsidized by the networking organization through support from the Gates Foundation. The equitly, quality and sustainability implications of this have not been evaluated and that is one of the aspects that would need to be better understood before replicating elsewhere. Training, recognizing and certifying these providers would open the door for them to be financed by mechanisms alternative to user fees. One other interesting experience is that of Accredited Drug Dispensing Outlets (ADDO) in Tanzania.
