F. Kincade, Director INTRODUCTION This is the Twentieth Report of the Division of Tuberculosis Control, and it covers the calendar year January 1st to December 31st, 1955. The Report is divided into six major sections of statistical tables showing the general summaries of the clinics of the Division, institutional admission and discharge summaries, B.C.G. summaries, tables on known cases and new cases of tuberculosis, and tuberculosis mortality. Certain amendments have been made to existing tables with a view to improving their usefulness. Brief narrative comments have been made as a guide to the more important features of these statistics, and graphs have been included with some of the tables to assist the reader in following time trends. Organizations set up for the control of tuberculosis must approach the problem and organize their forces for attack along four major fronts, namely, treatment, case-finding, prevention, and rehabilitation. Treatment for many years at the outset of the campaign demanded all the Division's attention, and the other phases gradually developed and increased in importance. As success was achieved on one front, greater resources could be shifted to strengthen the attack on other fronts. In the natural history of any disease, alleviation of suffering and prevention of death always becomes the first concern. When treatment becomes mastered, death rates fall, and in the broader aspects of control the emphasis must change from therapy to other phases of the problem. With the improvements that have taken place in therapy of tuberculosis, the cure of the disease now appears possible. For those developing the disease, recovery is almost a certainty. One might wish for more effective drugs, and undoubtedly they will be developed; but even with the tools presently at hand the treatment of tuberculosis can be said to be in a very satisfactory state. Therefore, the control of tuberculosis can be said to be in a very satisfactory state. Therefore, the control of tuberculosis is well into the transition stage and the emphasis in the Division's programme must shift from mortality to morbidity. This finds its expression in the new emphasis on case-finding and epidemiology, and the marshalling of forces for greater effort along this line. The case-finding effort in the Province is reflected in 354,025 chest X-rays taken in this programme throughout the Province during 1955. This represents a slight increase over the previous year and more than double the effort over the past ten years. A breakdown of the total examinations shows that 111,987 were done on hospital X-ray units, 83,852 of these having been taken as part of the admission X-ray survey and the rest as out-patients referred to local hospitals. A total of 105,700 examinations were done by the mobile X-ray units, one operating entirely in Vancouver and the other covering chiefly the smaller centres in the Province where X-ray facilities are not available. The remainder of the survey examinations, totalling 89,403, were done in the stationary units. Out of 307,090 survey examinations analysed, 381 new cases of tuberculosis were found. The active cases numbered 126, with the hospital admission surveys finding 26 cases and other surveys finding 100. The incidence of new active tuberculosis cases was 1 for every 2,437 survey examinations. However, in addition to new active cases, 71 previously known tuberculosis cases were relocated and found to be active by survey 13 L C 14 DEPARTMENT OF HEALTH AND WELFARE X-rays—24 by hospital admission X-rays and 47 by other surveys. This gave a case- finding rate for all active cases found of 1 per 1,677 hospital admission examinations and 1 per 1,518 examinations by other surveys. It is worthy of note that 24 or 48 per cent of the 50 active cases found through hospital admission surveys were previously known cases, whereas only 47 or 31.9 per cent of the 147 active cases found by other surveys were previously known. The case-finding rates vary in different localities, and the effectiveness of the Division's work is shown by the following analysis of active cases found in selected operations. Active Cases, 1955 (New and Previously Known Cases of Tuberculosis) Total Examined Number Rate Oakalla Prison Farm Metropolitan Health Unit _ Health unit at Courtenay Willow Chest Centre ... 5,222 120,214 1,603 30,072 41,759 82,852 10,362 11,232 4,668 35 38 2 36 47 88 11 7 1 1 in 149 1 in 535 1 in 801 1 in 835 1 in 888 General hospitals—admissions 1 in 941 1 in 942 1 in 1,604 1 in 4,668 The hospital admission X-ray surveys are gradually becoming more effective. The percentage of admissions examined by miniature X-ray has risen from under 40 per cent in 1951 to over 60 per cent in 1955. For those hospitals taking large X-rays, the percentage of admissions X-rayed gradually increased from 38.6 per cent at the beginning of 1953 to 55 per cent for the fourth quarter in 1955. The majority of hospitals are doing a good job of having their admissions X-rayed, while a few are falling down badly. For the last quarter of 1955 the results are as follows:— Hospitals Using- Miniature Standard X-ray X-ray 70 per cent or more of admissions X-rayed 14 14 50 to 70 per cent of admissions X-rayed 15 5 25 to 50 per cent of admissions X-rayed 9 13 Under 25 per cent 1 9 Totals 39 41 Every effort is being made to stimulate all the hospitals throughout the Province to provide adequate coverage for this programme. The programme is endorsed by the British Columbia Hospital Insurance Service and the British Columbia Hospital Association, and a spirit of competition is being developed amongst hospital administrators to do a good job, realizing the importance of finding tuberculosis for the protection of their staff, not to mention the economic significance to the hospitals when a case of tuberculosis is found and transferred to the Division of Tuberculosis Control, thus relieving themselves of the financial burden. Quarterly summaries of the results of the admission X-ray programme in each hospital are prepared and distributed to all hospitals and interested agencies. Those hospitals showing less than 50 per cent of their admissions X-rayed are brought to the attention of the local health authorities in hopes that they can be impressed with the importance of doing a better programme. When, through National health grants, it became possible to provide miniature X-ray equipment to all the major hospitals in the Province, as well as to a few health units and institutions, the idea of mass X-ray surveys was generally abandoned because it was possible to provide continuous X-ray coverage throughout most of the Province by the use of hospital equipment on an out-patient basis. For the outlying areas without J TUBERCULOSIS CONTROL REPORT, 1955 C 15 X-ray service, a mobile unit was made available to give a complete coverage on a biennial basis. The Division has now had four years' experience with case-finding in practically all centres in the Province, and these have been surveyed at least twice in that period. In this way it has been possible to establish incidence rates to determine how effective this work has been and to show where efforts should be directed in the future. On the basis of the figures prepared, it seems that while continuing to make X-ray facilities available throughout the Province, mass X-ray surveys are indicated in some centres, while in other areas this type of effort would be wasted. There is a tendency to judge the effectiveness of the survey by the number of people examined, and, by the same token, some surveys are planned on the easy accessibility of large groups of people and on the ease with which they can be organized for X-ray purposes. This obviously should not be a criterion; rather the Division must be guided by the tuberculosis experience in the area under consideration. Since the beginning of the streptomycin era in 1946, the Division has been reporting a marked reduction in mortality rates, which declined from 57.4 per 100,000 at that time to 9.7 per 100,000 in 1954. In 1954 the downward trend was slackened, having only been reduced from 11.5 in the previous year. This trend has now been reversed, and there were 137 deaths from tuberculosis during 1955. This changing trend has been noted in other parts of the world as early as 1951, but is only now apparent in British Columbia, and by many is considered to be in the nature of a delayed mortality of a number of advanced cases as a result of treatment with antimicrobials. The death rate in 1955 from the 137 tuberculosis deaths recorded was 10.5 per 100,000 population, as against a rate of 9.7 per 100,000 in 1954. This increase in tuberculosis deaths of approximately 15 per cent occurred chiefly among the older age- groups, where 83 deaths occurred in persons over 50 years, compared to 75 deaths recorded in 1954 for the same age-group. A continued reduction in deaths is evident in persons under 20 years of age. In 1954 there were 7 deaths in persons under 20 years, 4 of them being Indians. This year there were only 2 deaths reported for this age-group—1 white and 1 Indian. Tuberculosis deaths amongst whites increased by 14.6 per cent, from 89 deaths in 1954 to 102 in 1955, while deaths among Orientals for the same cause increased from 11 in 1954 to 14 in 1955. The Indian figure of 21 deaths in 1955 was a decrease of 2 deaths from 1954. In common with other places throughout America, the demand for beds for the treatment of tuberculosis in British Columbia continues to decrease. At the beginning of 1954 the Division of Tuberculosis Control was operating 935 beds. As the demand for beds decreased, the bed capacity was reduced to 788 with the closing of Jericho Beach Hospital one year ago. The highest occupancy of beds in the Division during the past year was in January, when there were 757 patients in institution. The highest number of patients at Tranquille during the past year was 337 in February. The bed capacity of the Division was further reduced to 773 in April of 1955 when it was determined that Tranquille Sanatorium should operate with the bed capacity of 325. At the end of October there were 770 beds within the Division for the treatment of tuberculosis and only 627 were occupied, with Tranquille Sanatorium having only 217 patients in the 325 beds provided, or 65 per cent occupancy. The units in Vancouver were operating to over 90 per cent of their capacity. In Victoria the administration of St. Joseph's Hospital found that the beds in Vernon Villa, presently and for many years used for tuberculosis cases, could be used for other types of illness, and with the demand for tuberculosis beds lessening, it was agreed that Vernon Villa would cease to operate as a tuberculosis institution. This further reduced the beds in the Division by 34 in number. For the fiscal year 1956-57 it has been decided that Tranquille Sanatorium will operate at a capacity of 278 beds, this being accomplished by the closure of the main building, and starting in April of next year the total capacity within the Division of C 16 DEPARTMENT OF HEALTH AND WELFARE Tuberculosis Control will be 689 beds, being a reduction of 241 beds in slightly over two years. In this connection it should also be noted that at the same time Shaughnessy Chest Unit has been almost entirely converted from a tuberculosis hospital to a non-tuberculosis hospital. At one time that institution was treating approximately 100 cases of tuberculosis. The Division of Tuberculosis Control has absorbed these cases and is now able to fulfil its contract to treat tuberculosis cases that are the responsibility of the Department of Veterans' Affairs. It had been expected that the admission of non-pulmonary tuberculosis cases to the Division of Tuberculosis Control might create a demand for large numbers of beds. However, this has not occurred. In 1955 there were only 20 cases of pleurisy and 56 with other extra-pulmonary tuberculosis out of 1,226 admissions to the Division's institutions. The census of the sanatoria populations taken on October 31st, 1955, revealed that there were 615 patients in these institutions. Of these, 364 patients were under 50 years of age and 251 over 50. There were 96 cases over 60 years old, 51 cases over 70 years of age, and 17 over 80 years of age. The sanatoria population over 50 years of age in institutions, and this represents 40.8 per cent of the total, has increased steadily from 32.3 per cent in 1952. A year ago there were 284 patients over 50 years of age in institutions, and this represented 39.5 per cent of the population. However, the greatest number of deaths is occurring in this group, and the reduction of 33 in total numbers of older persons in the Division's beds is probably accounted for by this fact. In persons over 50 years of age occupying beds, the males predominate in the ratio of 8 to 1, there being 223 males and only 28 females. Of the total admissions to sanatoria in 1954, the group of persons over 50 years of age represented 32.6 per cent, an increase from 26.6 per cent in the previous year. In bed occupancy, there are twice as many male patients as female in the institutions of the Division. An analysis of the length of treatment of discharged cases following first admission during the past year shows that of 706 discharges, 529 were treated under one year, representing 75.0 per cent of first admissions. These are as follows:— Cases Per Cent Treated 1 month 75 10.6 Treater 1 to 3 months 129 18.3 Treated 4 to 7 months 195 27.7 Treated 8 to 11 months 130 18.4 Among first admission cases, 56.6 per cent were treated under eight months. The length of treatment has shortened appreciably over the past year, when 45 per cent of the cases were treated less than eight months and 65.1 per cent were treated less than one year. An important development in the control of tuberculosis in the Province occurred in the past year, with the completion and opening of a tuberculosis hospital of 265 beds at the Provincial Mental Hospital, Essondale. For many years, segregation of the known tuberculous cases at Essondale has been practised under rather unsatisfactory conditions, with the patients isolated in wards in various buildings. The new building, which was specially planned and designed as an infectious-disease hospital, is most admirably suited to this purpose and provides excellent facilities for the treatment of mental patients with tuberculosis. Throughout the years the Division of Tuberculosis Control has worked very closely with those in charge of the mental-health programme, but with the opening of the new building an even closer relationship has been established. One of the specialists from the Division of Tuberculosis Control has been placed on the staff of Essondale Mental Hospital to supervise the tuberculosis treatment programme in that institution, and to TUBERCULOSIS CONTROL REPORT, 1955 C 17 carry on a programme of tuberculosis-control amongst the other patients and amongst the staff of that institution. This programme includes admission and periodic re-examination chest X-rays, as well as a tuberculin-testing and B.C.G. vaccination programme for all patients admitted to the institution, and a similar programme for the members of the staff. The present arrangement has greatly facilitated the handling of the mentally ill patient in institutions of this Division, and those problem cases can now be transferred in and out of Essondale in much the same manner as transfers between the Division's regular tuberculosis units. With a closer relationship established between the two services, a better understanding of the problem has been brought about, and better continuity in the treatment of the patient is possible. It is approximately two years now since it was decided that action should be taken under the health regulations to forcibly commit to our institutions tuberculous patients who are creating a public health problem in their community. Since then thirteen cases have been committed—eleven to Tranquille Sanatorium and one each to Pearson Tuberculosis Hospital and Shaughnessy Hospital. One case was committed in 1953, three cases in 1954, and nine cases this year. Eleven cases are still in institution, one having been discharged after a satisfactory treatment period and one having gone absent without leave. Seven of these patients are now at Tranquille Sanatorium, one at Essondale Mental Hospital, one at Shaughnessy Hospital Chest Unit, one at Willow Chest Centre, and one at Pearson Tuberculosis Hospital. The areas from which they have been committed embrace most of the Province and are as follows: Vancouver, 3; Victoria, 2; Powell River, 2; Fraser Valley, 2; Okanagan, 2; Peace River, 1; and White Rock, 1. Although committal powers have been used in only thirteen cases, their existence and the knowledge that they are being enforced has had a very salutary effect in many other instances. On numerous occasions when patients were threatened with committal, they finally submitted to voluntary admission. In many other instances, when warned of these regulations, patients in hospital who were about to leave against advice have remained in institution. For the most part, those patients committed to hospital under these regulations have not proved too troublesome and have accepted treatment when they found it was easier to co-operate than to continue to resist. However, it was necessary to transfer two patients to Essondale, one of whom has now returned to Tranquille Sanatorium. One would feel that the results of this method so far have been satisfactory, but it is apparent that the accommodation for the confinement of some of these patients in restraining areas within the Division is stretched to the limit, and only available at Tranquille Sanatorium. At the same time it is obvious that there are still many cases outside of institutions who are creating a public health problem and should be committed. In any future expansion, adequate facilities for the handling of this type of patient will be provided, but in the meantime each of this Division's institutions must be provided with properly constructed rooms for the confinement of recalcitrants. People who are suffering from tuberculosis and who are committed to penal institutions present a greater problem. When treatment has been needed, these cases have been transferred to Provincial institutions. For the most part, they are drug addicts and chronic alcoholics. These people are entirely unreliable, unco-operative, and unmanageable, and, in fact, objectionable to other patients and to the staff. In the recent case of a notorious drug addict and pedlar, the Division was requested by the Provincial Gaol to accept him because he was unmanageable in that institution. It is the considered opinion of this Division that proper hospital facilities should be provided at the Provincial Gaol for the treatment and management of many of these cases. There has again been a slight increase in the amount of money made available for tuberculosis-control through Federal health grants, the amount for the fiscal year 1955-56 being $366,070. During the previous year, projects were submitted and approved in r C 18 DEPARTMENT OF HEALTH AND WELFARE the amount of $313,477 or 89.2 per cent of the grant. Actual expenditures, however, amounted to only $249,417.14 or 71 per cent of the grant. This was in large part due to the fact that it was impossible to obtain delivery of equipment ordered by the cut-off date. This year, projects have been submitted and approved in the amount of $308,602 or 84.5 per cent of the amount available. In previous years a considerable portion of the grant has been used for the purchase of new equipment for the institutions and clinics, but this year the only approved requests have been for photographic equipment and an X-ray Vu-graph for the Willow Chest Centre and a Stryker bed for the Vancouver Island Chest Centre. Requests have been received for office equipment, but this is not normally provided from Federal health grants. The largest single project is for the hospital admission X-ray programme. The amount for this project is $109,574, which includes provision of survey X-ray equipment for three additional hospitals and payment to all general hospitals for admission films and for miniature films on out-patients. Some of the other major projects are as follows: Provision of antimicrobials, $48,000; community survey programme, $32,000; and rehabilitation programme, $26,000. The sum of $88,846 has been allocated for salaries. These positions are all within the Division of Tuberculosis Control, with the exception of two nursemaids at the Vancouver Preventorium and four X-ray technicians with the Metropolitan Health Committee. Under the professional education project, two members of the nursing staff are at present receiving postgraduate training at the University of British Columbia. A sum of $2,000 has been provided for short postgraduate courses, but, to date this year, little of this money has been utilized. All the projects during the current year have been continuations of projects from previous years, this being the first year that no new projects have been initiated. In an endeavour to promote a closer working relationship between local health services and the Division of Tuberculosis Control, and to provide a better understanding of the problems of the tuberculosis patient in the community and in the sanatorium, a co-ordinating committee was set up, composed of three representatives of the Division of Tuberculosis Control, three from the Medical Health Officers' group, and three from the central office of the Health Branch. This committee was to concern itself with those tuberculosis practices which have direct influence on and require a working relationship with local health services. The committee met on five occasions during the past year and discussed patient education, discharges from sanatorium, the significance of the positive culture in tuberculosis, criteria for admission, transportation of patients to sanatorium, records, and chest X-ray surveys. Through the deliberations of this committee, many troublesome problems have had a thorough discussion, with the result that a better understanding of common problems has come about. The success of the tuberculosis-control effort depends on many individuals and various organizations, both voluntary and official, that work in close co-operation with the Division to carry out the several phases of the programme. With post-sanatorium care developing to a greater degree and with case-finding and follow-up being intensified, the field health services have been called on to devote considerably more time to tuberculosis work, and a close working relationship has been developed between the Division and the field health services. The success of the programme depends entirely on the very close co-operation of these two groups, and this has been achieved and continues to be fostered by creating a better understanding of common problems. The British Columbia Tuberculosis Society, as in the past, has whole-heartedly supported the campaign both financially and through provision of services, particularly in the fields of case-finding and education. The Vancouver Preventorium Board continues TUBERCULOSIS CONTROL REPORT, 1955 C 19 to provide hospital facilities for the treatment of children, as it has for many years, and this group operates the only hospital for tuberculous children in the Province. The work of the Division of Tuberculosis Control also depends on the co-operation of many other departments and branches of government, such as the Welfare Branch, the Department of Public Works, the Civil Service Commission, and the Purchasing Commission. For all this assistance, without which the Division could not carry out a successful programme, sincere gratitude is offered. It is also desired to express sincere appreciation to all organizations and individuals who have co-operated so enthusiastically in the preventive programme of clinics and surveys, to the hospitals for their co-operation in carrying out the admission X-ray project, and to all the voluntary groups who continue to support the work of tuberculosis-control. To all the staff of the clinics and institutions of the Division who continue to maintain such a high standard of service, sincere appreciation of their loyal support is recorded.

TUBERCULOSIS CONTROL REPORT, 1955 C 33 An increasing number of X-rays are being taken by the institutions of the Division, with 5,196 taken in 1947 and 9,503 in 1955, in spite of a marked reduction in the bed capacity. This indicates the more exhaustive X-ray studies that are now carried out on the patients in institution because of the more advanced methods of treatment and the need for extensive investigations prior to surgery.

TUBERCULOSIS CONTROL REPORT, 1955 C 39 INSTITUTIONS—SUMMARIES During the year a tuberculosis institution was opened on the grounds of the Provincial Mental Hospital. This accounted for 261 admissions. Actually this does not represent 261 new tuberculosis cases under treatment in that institution, but for the first time they are all being brought together in one building. It is noted that the pneumoperitoneum refills in the institutions of the Division have been reduced from 2,614 in 1954 to 377 in 1955. There were eighteen pneumoperitoneum treatments initiated, against forty in the previous year. During 1955 the bed capacity at Tranquille Sanatorium was reduced from 340 to 268, at which point the main building at Tranquille Sanatorium was closed. In August, 1955, the bed occupancy reached its lowest point, with 217 beds occupied. The high point in occupancy during the year was in February, when 337 beds were occupied. There has been a decrease in the number of thoracoplasties, from 114 in 1954 to 74 in 1955, with an increase in the number of resections from 203 to 233. The increase in resections is in the number of lobectomies done.

C 40 DEPARTMENT OF HEALTH AND WELFARE This is the first year no initial pneumothoraces have been given. From this it is evident that pneumothorax has been discarded as a treatment for tuberculosis, although there are still many cases initialed in the former era who are still receiving refills. However, the pneumothorax refills have been reduced by 78 per cent in the past year, and there has been a reduction from 20,251 refills in 1951 to 2,385 in 1955.

C 48 DEPARTMENT OF HEALTH AND WELFARE INSTITUTIONS—DISCHARGES The number of persons dying in the institutions increased from sixty-seven to ninety-five, but in this total number there were more than a third who died of non- tuberculous conditions. Over the past five years there has been a decreasing percentage of patients discharged in the active unimproved category. The percentage of those discharged in the active classification has not altered greatly and 48 per cent were discharged in this classification. Because many were discharged on out-patient antimicrobial therapy although being negative, sufficient time had not elapsed to warrant them being placed in the arrested classification.

It is interesting to note that there were almost twice as many male discharges in the total as there were female, which might contradict the popular belief that the males are accumulating in our institutions to a greater extent than the females.

However, the incidence amongst Indians has been reduced from 10.2 per thousand to 7.5 per thousand. Further, it is noted that there is a marked reduction in new cases, both Indians and other than Indians in Area 9, which for some time has been the highest incidence area in the Province. In that area the number of new other-than-Indian cases has been reduced from 41 to 23 and the Indians from 90 to 26. The total incidence in this area has been reduced from 5.8 per thousand to 2.1 per thousand. It, however, still remains higher than the Provincial average of 1.1 per thousand.

This compares with a total of 646 new active cases diagnosed in 1954, with 486 other than Indians and 180 Indians. It is interesting to note that in 1955 there were 27 cases notified on death, as compared with 56 in 1954. In breaking down the active cases we find that 84 were primary, 197 minimal, 200 moderately advanced, and 106 far advanced.

In Table 55 it is noted that there is a further reduction in cases found in the younger age-groups. In 1954 there were 119 notifications in persons under the age of 19 years, compared with 95 in 1955. It is also of interest that in the non-pulmonary new diagnoses there has been a reduction in cases from 177 to 154.
