The best results from screening are usually obtained through
organized screening programs. Such programs have several
major components as outlined in the slide. Quite often
screening is offered in an ad hoc fashion, without these
organized components. There is interesting data from a
natural experiment in the Scandinavian countries which
shows that greater mortality reductions from cervical
cancer were obtained in countries that had organized programs.
Underlying a good organized screening program is an information
system to support its activities.
