Create an algorithm/formula

My company creates systems based approaches for the prevention of infection. I'm not a stats person, so I don't know the correct terminology to describe the kind of formula I need, but I do know the variables I'd like considered and a basic idea of what I'd like it to do. I'm really wanting to work in coordination with a stats person to bring my basic idea to it's highest potential. My Chief Medical Officer and I would be available to assist with researching the data necessary for the variables. If this works, it would be a really big deal and would help a lot of people.
