Can a medical researcher have too many publications?

The most prolific researchers may not be adhering to authorship guidelines

Medical research is a very competitive business, with a low success rate for grants and fellowships. To survive the competition, a researcher needs strong performance indicators, chief of which is the number of publications and associated citations. With publications, more is generally seen as better. However, I argue that very high publication rates should be seen as indicating poor authorship practices and should be discounted in evaluating track record.
