Intro To Epidemiology - Investigation 5-3: Evaluation Issues

  2. Hypotheses 1 How is this disease distributed? 2 Is there an association? 3 Is the association causal? 4 What should be done to prevent the disease? Was is worth the effort? Should we continue it? 5 Did the prevention strategy work? Where are we and where are we going? What’s my hypothesis? Did the exposure and the disease turn up together? Why did the exposure and the disease turn up together? What should I do? What should society do? Intro To Epidemiology - Investigation 5-3: Evaluation Issues

  8. Epi Speak Epi Speak Cost-Benefit Analysis A tool for deciding how to allocate money based on a comparison of the dollar value of implementing a risk management strategy (cost) to the dollar value of what the strategy will accomplish (benefit). Results in a cost-benefit ratio. Intro To Epidemiology - Investigation 5-3: Evaluation Issues
