[Knowledge management in medicine: in search of lost information].

This paper offers a brief review of the application of knowledge management in the field of the health sciences. This new current, which emerged in the business sphere, is seeking to win itself a space in disciplines characterised by their intensive use of information and which had traditionally assumed many of the proposals presented as novelties by these currents. The challenges and problems that knowledge management poses in the health sciences are discussed and, focusing on explicit knowledge management, solutions that are currently being developed are described.
