On the other hand, some nurses pay far too few visits because they have no head for planning their work, but linger, past all necessity, over unimportant details. To judge if a district is being properly visited, the superintendent should know the district, and she should also know her nurse’s capacity. To estimate the value of the day’s work by the number of visits alone, is like those societies who reckon their value by the number of pieces of literature they distribute, totally regardless as to whether any of it bears fruit. Roughly speaking, each patient should be visited once a week; failing this, once every ten days or two weeks. In a few exceptional instances, this time between visits may be still further extended, but this should happen only when the patient is doing extremely well, following all the rules, and giving efficient and intelligent co-operation. There are not many patients in this class—for the average, supervision to be adequate must be frequent. Very ill patients, however, must be seen two or three times a week—every day would not be too often, did the work permit. Unfortunately, if the visiting list is large, these sick patients can be visited only at the expense of other cases better able to take care of themselves. For this reason, the visits to ambulatory patients may become as infrequent as once every three weeks. If the visiting list grows so large that these infrequent visits are all that the nurse can give, then her instruction is laid on so thin as to be nearly worthless, a condition of affairs which calls for another nurse. =The Nurse’s Office.= An office is a necessity for the nurse as a place where she may keep her nursing and prophylactic supplies, and at which she will report at certain hours of the day, say at 9 A.M., at lunch time, and possibly again in the afternoon before going off duty. At certain specified hours, therefore, it will be possible to reach her, either in person or by telephone, and her office hours should be known to doctors, social workers, patients, or to any who have need to call upon her. In a small town or country district, there will of course be only one office, but in a city it will be necessary to have several branch offices, accessible to the nurses of the different districts. These branch offices should be situated on the border lines of two or three adjoining districts, so that one office may be used in common by several nurses. In a city there is also the central office, from which the superintendent directs the work, and where the staff nurses report daily.
