I'd argue that you definitely need a push-based model for preventative measures: vaccines, smoke detectors, Personal Protective Equipment to reduce the spread of disease.
If you don't know how serious a danger is, you won't start doing research on it until it actually occurs, at which point it is too late. It doesn't do much good to remind someone they need to have smoke detectors and check them regularly after the house burns down, or that a vaccine is available after they're infected.
