I don't think that's true at all. According to this paper: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2909426/ The number of new medicine journal publications significantly outpaces the number of new computers science journal articles per year.
Doctors are expected to keep up to date with the most recent research as part of their jobs, and they are payed to do so by going to conferences etc... I don't think the same can be said for software development.
