You have symptoms of problem and it helps narrow down. Need a massive database of all known diseases as well as symptoms / remedies. Chart location data for origin of specific disease, (less likely to be rabies if Australia etc) and probability from all factors.
Would require huge amounts of data as well as many man hours to create but a system that does this task would be one of most beneficial medical breakthrough possible right now in my eyes.
Especially in mental health where there are symptoms of many things over many separate disorder, or rare one. It would be a bonus if you could let this information to be fully public, especially if one could direct users to relevant places.
from what i know there's quite a strong resistance from doctors to working with software that automates their jobs. such software usually slows the doctors (he need to type etc) do it's hurts productivity. but to really gain the monetary benefit from using such software, a cheaper , and less knowledgable healthcare provider should use the software(for example nurse doing some jobs of the family doctor like in minute clinics, or family doctor doing some jobs of the specialist). As you can imagine ,shifting jobs between providers in the healthcare industry is not an easy job:)
Most docs would love more tech in their practices.
To give the most basic example, there is no formalized charting system in the Mental Health Industry. You have standardized notes that are turned into the county but that's about it.
The industry I work in (treatment of abused children who have been removed from the home) has a 96% fail rate in California. That means 96% of the children entrusted to the state end up in jail or dead by the age of 25 (as of 2003). So if ever there was an industry that needed technology's help it's this one.
