A New Model For Health And Disease – Page 25

if the etiology and pathogenesis were more or less known, the treatment would be rational and specific. This approach contrasted with later knowledge that recognized multiple subforms of every specific disease.6
Another model that emerged was the "curative" one, based mainly on the treatment of infectious diseases and vitamin deficiencies.6
More recently two more models have been proposed by the contemporary thinkers Weiner and Engel. That conceived by Weiner is more complex than its predecessors; social, cultural and behavioral factors are taken into consideration. The other model by G. L. Engel is even more comprehensive. In his treatise The Need for a New Medical Model: a Challenge forBiomedicine, he argues for a new model of medicine, asserting that this is necessary "to provide a basis for understanding the determinants of disease and arriving at rational treatments and patterns of health care; a medical model must also take into account the patient, the social context in which he lives, and the complementary system devised by society." 8
All these models appear to be rather simplistic, impractical and inadequate in their conception and scope, especially when health and disease are viewed from a broader perspective. Almost all of them seem to have been born out of efforts to justify "fashionable" medical practices rather than to postulate a priori a theoretical rationale on which medical thinking and practices could be based. Besides this, the problem of defining health and disease has not been solved, and this is perhaps due to the mechanical and oversimplified concept behind these approaches. Therefore, the necessity for a new theoretical Model that expounds upon the complexity and intricate nature of man appears to be crucial today.
