Nothing should diminish the enthusiasm for gaining new patients. The mere fact that a nurse has more than she can manage should never deter her from continually trying to find more. More patients, more patients, and even then, more patients, should be her constant aim—and then the chances are that she has not found all that exist. In Baltimore, when pioneer work was begun under the Visiting Nurse Association, that organization had a visiting list of some 1700 consumptive patients, divided among five nurses. As five nurses represented the largest number the Association could support, and as 1700 patients was only about one-fourth of those who needed care and attention, some other method of caring for the latter had to be devised. It was at this critical moment that the Health Department was persuaded to assume the tuberculosis work of the private association, and to incorporate it as part of the city machinery. If the need for this transfer had never been proved, it is hardly possible that the change would have been made. If the first nurses had confined their visits to the patients they could reasonably manage, and had refused to accept others, it would have been impossible to prove how great the number of infectious patients was, and how inadequate the care given them by the five struggling nurses of the private association. Therefore, each community which undertakes tuberculosis work should endeavour to unearth all the cases that exist, if for no other reason than to show the size of the problem, and the necessity of adequate measures for handling it. New patients, positive and suspicious, should be sought for from every possible source. This is better policy than to confine the work to the conscientious care of a handful of manageable cases. =Social Workers.= The agents of the Charity Organization Society, or similar associations, continually come across cases of tuberculosis. The new nurse should canvass all these agencies, and ask that all cases of this kind be referred to her. If a case is not positively diagnosed, that should be no drawback to reporting it; while the agents of these associations are laymen and therefore not able to make diagnoses, laymen, nevertheless, are able to make very shrewd guesses. It is the nurse’s duty to take charge of these doubtful cases, and get them examined and diagnosed by the proper agencies. The mere fact that a patient presents suggestive symptoms makes it all the more urgent that he be examined as soon as possible, and lack of positive diagnosis should be no reason for the agent to withhold, or for the nurse to refuse to take charge of, such a case. To visit a suspect does not necessarily classify him as a consumptive, while not to visit him might be to deprive him of assistance at a most critical time.
