This small program, designed for use in a hospital pharmacy setting, runs on Windows and calculates BSA estimates using a variety of formulas (Boyd, DuBois & DuBois, Gehan & George, Haycock, and Mosteller). It was recommended by ISOPP, the International Society of Oncology Pharmacy Practitioners, to its members.
