[The economical use of methods employed in the diagnosis of jaundice: decisional attitude as opposed to diagnostic attitude (author's transl)].

For the diagnosis of jaundice, a comparison is established between a classical diagnostic attitude and a decisional attitude which consists in guiding and restricting the investigations according to the therapeutic possibilities. It appears from the comparative study of the two groups of patients that the decisional attitude is better, resulting in a treatment which occurs earlier, is less expensive and probably of a better quality.
