=Object of Work.= The object of tuberculosis nursing is the home supervision of all persons suffering from pulmonary tuberculosis. This supervision should include patients in all stages of the disease, and not be limited to those who are in some particular stage, such as early, in contradistinction to advanced, cases. No organization which expects to do effective work should deal with one class of patients alone, since the boundary lines between the different stages are constantly shifting; the ambulatory case of to-day may be the bed-ridden case of to-morrow, and _vice versa_, and any attempt to limit the nurse to one class or the other would mean neglect of both. Unless the work is planned on such inclusive lines, it will be necessary to place a second organization in the field, to care for those cases which have been thrown out by the first. Policy of this sort would mean a number of similar organizations, duplicating and overlapping each other’s work at every turn. Thus, in the same household, we should see the early, ambulatory patient “advised” by the nurse of one organization, while the advanced, bed-ridden, more infectious case is being bathed and cared for by the nurse from another. Invidious comparisons would doubtless be made by the family, with the decision in favour of “deeds, not words.” True, there would be co-operation between these two societies,—which would mean, as a rule, double work, duplication of visits, endless transferring of cases backwards and forwards, and opening and closing of records. From whatever point of view we consider it, this is a very poor plan of work, and a wasteful method. The nurse should be in a position to follow the fortunes of her patients for months and years. Any scheme which involves transferring him to a stranger, from an old friend to a new, at the moment when he slips from an early into a most infectious stage, is to lose sight of him and of his family at a most critical time. Adequate supervision means that the nurse must teach, nurse, and ferret out patients, and her patients must include advanced, early, and suspicious cases. The care should be of two kinds—instruction as to the nature of tuberculosis, with general teaching along the lines of prevention and prophylaxis; as well as actual nursing service, rendered to advanced and bed-ridden cases. The Baltimore nurses take charge of all tuberculous patients, in whatever stage, and we feel that this is the most effective way to carry on the work.
