The hospital under such circumstances would become a centre from which community work of the highest value would radiate; and patients, private practitioners, and the staffs of hospitals would alike live in a new world in which the interest and efficiency of medical work would be greatly increased. The present irregular localization of hospitals makes the realization of such a scheme difficult; but local partially successful schemes are already in operation; difficulties can be overcome with good-will; and eventually we may hope to have for each unit of subdivided public health administration and as an organic part of this, a hospital, with out-patient or dispensary clinics, and radiating from these the various forms of medical attendance, domiciliary nursing, public health nursing, and sanitary supervision which are needed. In securing such a result there will be needed medical practitioners who are imbued with the ideals of preventive medicine in its widest sense. Let me, in this connection quote the following extract from a recent official report of my own: There is needed a reconstruction of the training of each medical student, which will make preventive medicine in its widest sense an integral part of his training, and will insure that before he begins practice he has definite instruction in the application of the whole of his knowledge to preventive purposes. The past conception by the public of the relation of medical men to the community—apart from the special case of medical officers of health—has been mistaken. The doctor has been regarded as a help when serious or acute incapacitating illness occurs, and he has but seldom had the opportunity of giving advice in the earlier and more controllable stages of illness. His training has been conducted on the assumption that his chief rôle should be on present lines, with the result that most medical practitioners enter into practice with a too scanty knowledge of hygiene and preventive medicine, and have to learn slowly in belated experience the influence of environment on the health of their patients. The teaching of medicine should be much more largely physiological and hygienic than at present, and such subjects as food values, the hygiene of infancy and childbirth, the physiology of breast feeding, and the influence of environment on the health of their future patients should be the subject of careful training—especially in regard to housing, feeding, clothing, and conditions of work. Were this done, the ideal condition, in which each medical practitioner becomes a medical officer of health in the range of his own practice, would approach realization.—[Annual Report to the Local Government Board, 1917-18.]
