The proper utilization of data information systems in mental health care can noticeably improve the quality and efficacy of such care. The World Health Organization is in a key position to encourage and assist governments in achieving the fullest possible application of knowledge in the development and utilization of such systems to the benefit of the greatest numbers of the world’s population.This paper briefly delineates some of the common information needs of the providers of mental health care, discusses the feasibility of automated data systems, and describes some already existing psychiatric information systems. Finally, it proposes ways and means by which the WHO can more efficiently aid its member nations by coordinating efforts in establishing mental health information systems. Recommendations include establishment of an information clearinghouse on data systems, a group coordinating dissemination of this information, a common pool of specialists in the area, and development of regional computing facilities under the auspices of the WHO.
