A triaxial classification of health problems presenting in primary health care. A World Health Organization...

Over the past two decades, research in a variety of countries and settings has revealed the extent to which psychological morbidity and social problems constitute an important proportion of primary health care contacts, either in their own right or in association with physical ill-health. The development of appropriate responses, medical and non-medical, to such problems is, in part, hindered by the relatively low level of awareness concerning the significance of such problems and by currently inappropriate methods of describing and classifying health care problems in the primary care setting. There is a pressing need for an appropriate, relatively simple and flexible classification or list of problems presenting in primary care. This study describes the development, under WHO auspices and in an international setting, of a triaxial classification of health problems and the testing and modification of the classification by means of an international case vignette rating exercise. A psychological problem list and a social problem list, together with detailed glossaries, suitably modified in the light of experience derived from the study, are described, and proposals enumerated of possible ways in which these lists might be further developed and used in research and clinical undertakings in primary care.
