> roads to take people to hospital

The population density in some developing countries is extremely low. Botswana for example has roughly 2mio inhabitants of which roughly a quarter live in Gabs and yet another maybe 10% in the next 5 bigger towns. That leaves the rest of the country with an average population density of less than 2person/square km. Bringing people to a hospital by car on a good road can easily take a day or more. It's also not viable to have an educated doctor able to make that choice in each of the remote villages. So you really really need to find a good way to offload that decision to a person that's remote.

n.b. Botswana is a fairly well developed country, I just choose it as an example since I have family ties there and know the situation better than say Namibia which is similar in the population distribution.
