Kincade, Director INTRODUCTION Probably foremost in our minds at the time of the last Annual Report was the reduction of the waiting-list and its eventual elimination through .the opening of the Pearson Tuberculosis Hospital in May, 1952. This opening so markedly reduced the waiting-list that at the present time there are less than fifty people waiting for beds in our Provincial sanatoria. The remodelling at Tranquille Sanatorium was completed, and, as a result, fifty additional beds were made available near the end of the year. When these beds are available and the Pearson Hospital is finally staffed and working to full capacity, the present waiting-list will undoubtedly be eliminated. However, it should be pointed out that the present waiting-list is from a highly selected group, and undoubtedly additional cases could benefit from a sanatorium regime or should be in a sanatorium for the protection of others. If these standards for admission were applied, the expansion of Pearson Hospital to its eventual capacity of 528 beds would undoubtedly be required. One of the biggest jobs in the Division during the past year was the setting-up of a personnel section and the clarification of staff complements to cover all the activities of the various units so that this phase of the work would be put on a sound basis. This was a long and painstaking procedure and, when applied to almost a thousand members of the staff, represented a great deal of work and detailed study. During the critical period in the spring when a large number of appointments and transfers were necessary with the opening of Pearson Hospital, this work was greatly retarded by the resignation of the first personnel assistant. However, with the appointment of the present personnel assistant the organization has come along rapidly. It is expected that when the personnel section is properly organized and the office routine set up, the personnel assistant will be able to devote considerable time to the investigation of office procedures and organizational work. As forecast in the last Annual Report, the two largest sanatoria have now the services of trained administrative assistants. The purpose of these positions is to relieve the medical superintendents of all that part of the work directly related to business so that the superintendents may confine most of their attention to the gradually expanding medical organization necessary for the treatment of tuberculosis. The administrators, having had formal instruction and experience in hospital management, should improve further efficiency in our sanatorium operations. NATIONAL HEALTH GRANTS National health grants continue to be of great assistance to the Division. To date $294,000 has been allocated of the $370,329 made available by Ottawa. Approximately 58 per cent of this amount is being used in continuing projects, but new and improved services were also provided under these grants. The X-ray services were expanded with the installation of photoroentgen equipment at Burnaby Hospital, University of British Columbia Health Service, Mission Hospital, Dawson Creek Hospital, and Abbotsford Hospital. Additional darkroom installations are being provided for three health units. Equipment was provided this year to complete 13 F 14 DEPARTMENT OF HEALTH AND WELFARE the furnishing of the pathology laboratory at Tranquille and the departments of respiratory physiology and physiotherapy at the Willow Chest Centre. A project is now being considered for the modernization of the X-ray department at Tranquille. Approval has been obtained for the expansion of the admission X-ray programme to the smaller hospitals in the Province. At the present time this service is provided only in those hospitals large enough to warrant the provision of photoroentgen equipment. It is now planned to pay all the smaller hospitals $2 for each chest X-ray taken on admission, using their own equipment. Assistance continues to be provided for postgraduate training. During the year one doctor completed his training and returned to the Division. At the present time three nurses and one doctor are receiving postgraduate training, and a project is being submitted for the training of a second physician. One of the staff is taking a course as a medical- record librarian and will return to the Division in that capacity. Funds are available for short courses for senior personnel, and two members of the staff took such courses during the year. Throughout the various units of the Division, eighteen members of the staff are being paid through National health grants. Plans are being made for the expansion of the rehabilitation programme by providing rehabilitation officers for both Tranquille and Pearson, and expansion of the physiotherapy service by providing a part-time physiotherapist at Tranquille. The project to provide P.A.S. and streptomycin was enlarged to provide isoniazid as well. Approval was not received for the continuation of the out-patient occupational therapy or the home-care service in the Vancouver area. The payment for streptomycin injections in the home was also discontinued. TRENDS IN THE TREATMENT OF TUBERCULOSIS In reporting the work of the Division of Tuberculosis Control the changing concepts in the treatment of this disease should be pointed out. From the extensive studies that have been made through the use of streptomycin and P.A.S., it is now evident that resistance of the tubercle bacillus to streptomycin can be, to a great extent, controlled by its combination with P.A.S. and its use in smaller dosages over long periods of time. With the fear of resistance removed, it is now possible to treat and control tuberculosis in over 75 per cent of cases with resistance developing and without toxic effects on the patient. This has greatly broadened the use of these drugs, and it is now felt that if a patient needs treatment for tuberculosis, he should have antimicrobial therapy. Where formerly patients were treated from three to six months, they are now being treated from one to two years and even longer with these drugs. The addition of isoniazid to the armamentarium has further broadened the attack against tuberculosis, so that medical cures can frequently be expected. With the advances in chest surgery and refinements in techniques, pulmonary resections are commonplace and, in fact, may soon outnumber surgical collapse procedures. Where formerly we hoped for arrest of the disease, we now strive for eradication. This new approach, while offering great hopes to patients, is also stimulating to those who conduct their treatment. However, it does put the treatment of tuberculosis on a highly technical plane and requires extensive investigation of patients with modern equipment. Nevertheless, there is no doubt that when patients are treated in this way the relapse rate will be greatly reduced. DEATH RATES The death rate from tuberculosis in 1951 continued to decline, and a rate of 18.9 per 100,000 was recorded for the other-than-Indian population, as against 21.6 the TUBERCULOSIS CONTROL REPORT, 1952 F 15 previous year. The final corrected death rate for 1951 for the total population was 25.1, as against 27.5 in 1950. Since 1946 the annual number of deaths has been exactly cut in half, from 576 to 292. This reduction in mortality continued in 1952, there being 215 deaths, compared with 292 in 1951. This was chiefly due to a considerable reduction in Indian and Oriental deaths. The mortality rate in 1952 for the total population was 17.9 per 100,000, as against a rate of 25.1 for 1951. While the tuberculosis death rate for British Columbia approximates the death rate for Canada and is reasonably satisfactory considering the rate of reduction, there is one area in the Province where the death rate for other than Indians is three times that of the average. This indicates the need for a concentrated effort in that area. It is pleasing to report that discussions have already been held and plans are being laid for a special effort in that area. TUBERCULOSIS IN OLDER PERSONS For some time the problem of tuberculosis in the older person has given some concern. From the Annual Reports it will be seen that the incidence of tuberculosis in this group is becoming more apparent, and that the death rate by age-specific groups is higher than in other groups. However, it should be pointed out that for the older persons the death rate is falling, as in the younger age-groups. It is also apparent that this problem is more serious among the older male patients than among the older females. This is confirmed by an analysis of patients in sanatoria at the present time. As of October 20th of this year a spot survey was made, and it was shown that 552 beds were occupied by males, while 286 were occupied by females—a ratio of almost 2 to 1 for the males. Of the 552 male beds, 252 or 45.6 per cent were occupied by persons 50 years of age and over. Of the 286 female beds, 24 or 8.6 per cent were occupied by persons in these age-groups. In all there were 276 persons, 50 years of age and over, occupying 32.3 per cent of the total of 838 beds. In view of the fact that 24.4 per cent of the admissions in 1951 were for patients 50 years of age and over, it is apparent that these people tend to accumulate in sanatoria. The trend in admissions is also interesting because in 1947 this group represented only 16.7 per cent of the admissions. From this it is apparent that special consideration must be given to this problem by this Division. The first consideration that presents itself is in respect to accommodation. Is a highly developed medical service required to treat this type of patient or would ordinary convalescent care be sufficient? Is there any justification in restricting this type of patient to a strict sanatorium regime, when most of them have little hope of cure and have, for the most part, already received the maximum benefit from sanatorium care? In any event it is apparent that tuberculosis in the older person is becoming one of our greatest problems, and closer study of this problem than has been given in the past must be carried out. X-RAY PROGRAMME At the time of the last Annual Report it was pointed out that the work of the mobile survey unit would need critical review to determine a future course in this matter. The work for 1951 was analysed, and, as a result of this analysis, it was shown that this was not an expensive undertaking compared to other methods, and that the yield in cases found was very satisfactory. The cost of 42 cents an examination compared favourably to the rates paid to hospitals for miniature films, and the case-finding rate of 2.2 cases per thousand compared favourably with other clinics. It was therefore recommended that this service be continued, particularly where it reached into areas that otherwise could not be covered. It was also decided that the mobile X-ray programme should be on a continuous basis. This Division is grateful to the British Columbia Tuberculosis Society for providing a new truck and generator, which should enable us to carry out this work in every part F 16 DEPARTMENT OF HEALTH AND WELFARE of the Province. There was an unavoidable delay in starting this work in the fall due to non-delivery of equipment, but it was undertaken, and the unit continued to work in the Lower Fraser Valley until the end of the year. At the first of the year it will be available for work on Vancouver Island, and it is expected that the summer season will be devoted to work in the Interior. It has been asked that all areas of the Province submit their requests for use of this equipment so that the itinerary can be planned. Once this is established, it is hoped that a pattern can be developed so that the unit may move continuously throughout the Province each year, it being understood, of course, that it will no visit those areas that have been supplied with photoroentgen equipment. In spite of a great deal of effort, the results from admission X-ray surveys have not been as good as was anticipated this year, although there was an improvement over the previous year, there being 46,384 admission X-rays during 1952, as against 28,700 in the previous year. It is to be hoped that this showing will improve because the programme is backed by all the official organizations connected with hospitals, particularly the British Columbia Hospital Insurance Service, which has taken an active interest in this work and is attempting to stimulate the hospitals to make a better showing. The staff of the Division must take every opportunity to promote this work and point out its advantages both to the staff of the hospitals and to the patients. When some of the larger hospitals are approximating 90 per cent examination of admissions, it is difficult to understand why in smaller hospitals, where the organization is less complicated, similar results cannot be achieved. However, it is encouraging to note that most hospitals, where requested, have co-operated very well in the examination of out-patients. While the poor showing in respect to admissions is to be regretted, it must be remembered that it is of considerable importance that this examination was made available for out-patients. Encouraged by the Chilliwack experiment, where an organizational plan for canvassing the population to have chest X-rays at the survey unit in the hospital was carried out, the British Columbia Tuberculosis Society is considering provision of an organizer to expand this work to other centres in the Province. In this way it is hoped that all of the centres with photoroentgen equipment will be organized along the same lines as Chilliwack, and that a continuous survey at each centre will be carried out. Credit should be given here to the members of the Junior Red Cross of Chilliwack, who gave splendid co-operation. In 1952 there were 190,558 X-ray films taken in the clinics of the Division, general hospitals, and health units, as against 196,872 in 1951. TRAVELLING CLINICS It is pleasing to report that the district work of the Division through travelling clinics is now on a more satisfactory basis. Because additional staff was made available through new appointments, medical consultants are now able to accompany the travelling clinics on their visits to the various areas. This has long been desired, and its accomplishment makes for the provision of a better medical service and the promotion of closer relations among the Division, the health units, and the practising physicians. When consideration is given to the fact that a third of our known cases, or approximately 5,000 persons suffering from tuberculosis, are scattered throughout the smaller centres of the Province, and that their follow-up and supervision must be carried out by the travelling clinics and the field health service, it can be seen that the provision of the necessary services is a considerable task. NEW CASES The number of new cases discovered during the year amounted to 1,383. This was a reduction and was partly due to changes in the system of notification whereby cases which are healed on diagnosis are not included in the central index of known cases but TUBERCULOSIS CONTROL REPORT, 1952 F 17 are followed by public health personnel on a referral basis. However, over and above this there was an actual reduction in the number of new cases in 1952, but the extent of this reduction is difficult to estimate. The new cases, broken down into racial groups, show the following: Indians, 282; other than Indians, 1,101; and into age-groups:— Indians 0- 4 34 51 40 36 29 14 24 15 15 5 12 7 Other than Indians 0- 4 . 43 5- 9 5- 9 10-14 15-19 29 10-14 15-19 22 56 20-24 20-24 94 25-29 25-29 113 30-39 _ 30-39 40-49 50-59 60-69 70-79 ?05 40-49 _ 168 50-59 60-69 70-79 139 120 75 80 and over Not stated 80 and over Not stated 19 18 The sources of reporting of new cases during the year were as follows:— Stationary clinics: Tranquille, 10; Vancouver, 388; Victoria, 44; and New Westminster, 69. Travelling clinics: Interior, 46; Coast, 50; Island, 18; and Kootenay, 39. Reported from outside the Division of Tuberculosis Control, 719. SOCIAL SERVICE During the year there was almost a complete change in the personnel of the Social Service Section, but in spite of this a full complement of workers was maintained, and the Section is now fully staffed. A new policy of referral of patients was established, and is working out most satisfactorily. Instead of waiting for a crisis to develop before a patient is referred to the Social Service Section, it has become routine where social-work staff is available for all newly admitted patients to be visited by the ward social worker soon after admission. The purpose of this introductory visit is twofold—to acquaint the patient with the kind of help that is available to him from the Social Service Section and to give the social worker an opportunity of getting to know something about the patient as a person and how he is responding to the pressures that are part of a long-term disabling condition. In all the work on the wards the closest team relationship is maintained with the doctors, the nurses, the rehabilitation officer, and other allied workers in order to achieve the common goal, which is to help the patient accept his tuberculosis and fight it effectively with the weapons which are available to him in the hospital setting. The home-maker service, instituted in 1948 under National health grants to provide housekeeping assistance in select homes of tuberculosis patients, was discontinued in 1952. The purpose of this service was to assist in relieving the acute shortage of beds existent at that time. It was designed as a short-term project, and discontinued because it was felt that the opening of the Pearson Hospital would relieve the shortage. NURSING In preparing the report on the nursing services for the past year, there does not seem to be a great deal in the general picture that can be considered as entirely new, but steady progress has been made toward maintaining standards and improving services to the patients. The time seems opportune, therefore, to review the changes and developments F 18 DEPARTMENT OF HEALTH AND WELFARE that have entered into the reorganization and expansion of the nursing services during the past decade. Four factors that stand out as a basic part of the nursing organization are as follows:— (1) The educational programmes for tuberculosis nursing at the undergraduate and graduate levels. (2) In-service education for orientation of new staff, both auxiliary and professional nursing personnel. An article was prepared on the programme at Tranquille for publication in The Canadian Nurse. (3) Review and subsequent standardization of procedures and isolation technique to arrive at uniformity for the various institutions throughout the Division. This is important because lack of uniformity, among institutions or among wards, can result in confusion. (4) Studies made toward developing patient-centred care, which included staff quota requirements and demonstrations and experiments with the team nursing plan. Under the team plan, assignments are based on patients' needs rather than ward duties; for example, a group of patients is assigned to a professional nurse who is responsible for their total nursing care, including the supervision of the duties done for them by auxiliary personnel, aides, and orderlies. General staff nursing, done under this pattern, is proving satisfactory from two standpoints: (a) Better over-all care for the patients, and (b) greater satisfaction for the staff nurse. However, it should be pointed out that successful implementation of the team nursing principle is dependent on three important requirements:— (1) Adequate numbers of well-prepared staff who are physically and professionally able to carry full responsibility for a group of patients and direction of auxiliary-staff members. (2) A proper proportion of professional and auxiliary staff in relation to the patient quota and volume of nursing-service requirements. (3) Convenience of physical layout of ward, patients' rooms and service areas, and adequate equipment. Much planning, organization, and staff education are still necessary before the team nursing plan can be implemented successfully in the various institutions of this Division. Nevertheless, actual experimentation with the plan has progressed to the extent that the Division's nursing service was invited to present a demonstration on team nursing to the Western Canada Institute for Hospital Administrators at the workshop which was arranged by the School of Nursing at the University of British Columbia for the nurse representatives to the Institute. Additional factors that have a direct bearing on the nursing service are as follows:— (1) The need for review and subsequent revision of practices and policies on such routines as charting. Elimination of time-consuming and repetitive routines would tend to make more time available for the nurse to spend at the bedside or in consultation with co-workers, allied workers, relatives, and patients in the interests of better care and understanding of the patients. (2) Instruction for orderlies: The setting-up of a basic course of instruction and demonstration on essential procedures would strengthen and improve patient-care. Implementation would be at the local level. TEACHING PROGRAMMES As in previous years, a variety of teaching programmes was undertaken to provide instruction in tuberculosis nursing. The majority of nursing students were undergraduates from Mainland hospitals. These students spent five weeks with the Division. TUBERCULOSIS CONTROL REPORT, 1952 F 19 A lesser number from Victoria hospitals attended classes for one week in Vancouver and then returned to Victoria for clinical experience. The teaching programme also included practical-nurse students and public-health- nurse students, who undertook courses or attended programmes planned to provide experience. The number and types of programmes were similar to those conducted in the previous year. The Pearson Hospital, the Jericho Beach Hospital, the Willow Chest Centre, and the New Westminster Chest Clinic are all being used for student experience. GENERAL At this time, mention must be made of the splendid co-operation among parts of the Division and of the excellent relations with other departments of Government. The Division of Tuberculosis Control must depend on a great many agencies to carry out its programmes and to conduct its day-to-day business. It is therefore gratifying to be able to state that every assistance possible has been extended to this Division. With other organizations, such as the Indian Health Service, the closest and most cordial arrangements for mutual assistance have been maintained. The British Columbia Tuberculosis Society, as in the past, has been a tremendous force in the campaign against tuberculosis. The work of the Preventorium Board is also noteworthy in that it provides the facilities, not available within the Division, for the treatment of tuberculous children. Plans are at present under way for the expansion of the Preventorium from forty to eighty beds. To all these and many other organizations who assist in this work, the Division, therefore, records its sincere appreciation.

Harrison Mills Hope Examinations at the diagnostic and treatment clinics of the Division totalled 38,802. This is a slight decrease from 1951, when 40,266 cases were examined. This reflects the use of hospital miniature-film surveys as a screening method, so that diagnostic clinics confine their services more and more to known and suspected chest conditions. New examinations showed a 21-per-cent decrease from last year, while there was a slight increase in the number of re-examinations. Of the 38,802 examinations made, 15,024 or 38.7 per cent were between 30 and 50 years of age and 10,918 or 28.1 per cent were over the age of 50 years.

Among the new cases found, 412 or 62.0 per cent had minimal pulmonary tuberculosis, and 131 or 19.7 per cent had moderately advanced pulmonary lesions. The number of cases with inactive or arrested tuberculosis totalled 193 or 29.1 per cent, 305 cases or 45.9 per cent were classified as active, while there were 160 or 24.0 per cent in whom the clinical status was not determined at the time of reporting. During 1952 the recommended National Tuberculosis Association's notification for tuberculosis was adopted. This eliminated certain healed tuberculous cases previously included in the case register of tuberculosis and accounts for some of the reduction in new cases found.

' TUBERCULOSIS CONTROL REPORT, 1952 INSTITUTIONS F 39 The number of patient-days increased from 273,960 in 1951 to 286,827 in 1952. This increase may be due partly to the opening of the new Pearson unit, which recorded a total of 37,263 patient-days. The decrease in initial pneumothoraces from 201 in 1951 to 119 in 1952 and the increase of pulmonary resections from 40 in 1951 to 90 in 1952 indicates the changing trends in the treatment of pulmonary tuberculosis.

It is also interesting to see that the notifications are down about 50 per cent from the peak year of 1947, when 2,616 new cases were reported in spite of intensified case-finding programmes. It is worth noting, however, that among the other-than-Indian group there was a small percentage increase in cases diagnosed as primary and far advanced, and in some non-pulmonary lesions. Among Indians, small percentage increases are noted among cases diagnosed as minimal and in some non-pulmonary lesions.

Source: Death Registrations, 1952. F 76 DEPARTMENT OF HEALTH AND WELFARE The death rate from tuberculosis in 1952 continued to decline, and a rate of 15.4 per 100,000 population was recorded for the other-than-Indian population, as against 18.9 the previous year. The death rate in 1952 for the total population was 17.9, as against 25.1 in 1951. Deaths among the Indian population showed a considerable reduction, there being 35 deaths in 1952 for a rate of 120.7, compared with 77 deaths in 1951 for a rate of 270.2 per 100,000 population.
