Research, Research, Research

Another major aspect of Simply Hospital is research: you need to keep researching in order to increase the chances of having the correct illness diagnosed and then cured: doing so increases the reputation of your hospital, which results in more patients, which in turn generates more money. So try to research continuously and I would recommend getting all the diseases at around 80% first instead of mastering them one at a time.

Patients with different types of illnesses will visit your hospital with the hope of being cured. Each illness has its own degree of complexity and if it's a new strain, it takes some research before it can be diagnosed and cured.

Constantly research diseases increasing diagnosis accuracy and effectivity of the cure. There is no point to spend money on researching a disease ahead of time especially if you haven't reached a certain level where patients start to visit with that illness. Research is expensive and you'll have a better chance with old illnesses first.

Looking at the image above, you'll know how the level you are at, how long it takes to complete the research, the cost and percentage of increase. As an example, Zombie Syndrome is at level 5 and after the research is done, it will increase the success rate of diagnosing it by 8% and 5% for curing it.
