A New York Times Story:

Doctorates are popping up all over the health professions, and the result is a quiet battle over not only the title “doctor,” but also the money, power and prestige that often comes with it.

…For decades, a bachelor’s degree was all that was required to become a pharmacist. That changed in 2004 when a doctorate replaced the bachelor’s degree as the minimum needed to practice. Physical therapists once needed only bachelor’s degrees, too, but the profession will require doctorates of all students by 2015 — the same year that nursing leaders intend to require doctorates of all those becoming nurse practitioners.
