[Notification of cancer in breast cancer patients].

The notification of the name of disease is a premise for making the system of informed consent more complete in case of cancer treatment. In Japan, however, the notification of cancer can hardly be said to have an attained social consensus. Considering that the notification can ultimately improve patients quality of life (QOL), the breast cancer group of our department informs all breast cancer patients of their diseases in principle. This paper reports and discusses the results of a survey by questionnaire on the notification of cancer in 100 patients with breast cancer. The notification of cancer was received favorably in 83% of the patients. For those who answered, the explanation on the notification was convincing and it accounted for 81%. An examination of background factors of patients who had not been convinced revealed that many of them were suffered from advanced cancer. After the notification, a human relationship with the family and friends aggravated few of them and improved in 30% (family) and 18% (friends), respectively. The notification of cancer was thus suggested to contribute to the improvement of QOL. Although 83% well received the notification of their own diseases, only 21% were affirmative for the notification of cancer in case of a member of the family. We medical professionals should make a further effort not to make the notification of cancer the pronouncement death but to make it an aid for patients to live better.

Trends in hepatitis B notifications 1976-87.

This paper considers trends in hepatitis B notifications in New Zealand during the period 1976 to 1987. It attempts also to demonstrate the fact that although notifications are never comprehensive, even incomplete statistics can give a reasonable and useful indication of trends. Since 1985 most districts have shown a gradual and persistent decline in notification rates. High notification rates are observed from Whangarei, Auckland, South Auckland, Rotorua, Gisborne and Hutt health districts. With a notification rate of 54 per 100,000 population in 1984 Whangarei health district gave the highest rate during this period. These observations are consistent with what is known from other studies about the geographical distribution of hepatitis B markers. Peak notification rates occur in the 15 to 25 age group with highest rates in groups of nonEuropean ethnicity. Notification rates within each district over the eleven year period are compared to the national rates. Further analyses by demographic factors based on information available for the year 1987 are presented. Again the highest rates are observed in groups of nonEuropean ethnicity with the Maori and Pacific Island populations showing rates of 27.2 and 23.0 per 100,000 population respectively. For the eleven year period notification rates for all types of infectious hepatitis are compared to identify secular trends. It is seen that hepatitis A notification rates have declined since the mid-1970s while rates for nonA nonB hepatitis and acute nonspecific hepatitis rose sharply in the early 1980s and have since declined slightly in 1986 and 1987.

Notification of tuberculosis: how many cases are never reported?

BACKGROUND: Notification of tuberculosis is essential for local contact tracing and for assessing the national incidence of tuberculosis. The accuracy of notification figures is uncertain. This study examined the notification rates of all patients diagnosed as having tuberculosis at two hospitals in the East End of London over five years. METHODS: In a retrospective survey of all patients aged 16 years or more presenting with tuberculosis to the London Chest Hospital or the Royal London Hospital from 1 January 1985 to 31 December 1989, cases of tuberculosis were identified from microbiology and histology records, statutory notifications, necropsy reports, coroners' records, hospital activity data, and death certificates. Clinical data were obtained from case notes and notification was determined from the local authority notification lists. RESULTS: Six hundred and nine adult patients with tuberculosis were identified. Notes were available for 580 cases (95%), of which 426 (73%) had been notified. The proportion of cases notified varied according to the specialty of the clinician in charge of the patient at diagnosis. Patients with a past history of tuberculosis and those who died within one year were less likely to have had their tuberculosis notified. Age, race, and lack of microbial or histological confirmation of diagnosis did not influence the proportion of cases notified. One hundred and eighty five patients had smear positive sputum, but 25 of these cases (14%) were not notified. Eighty five patients who had presented with pulmonary tuberculosis did not have their disease notified; 20 (24%) had smear positive sputum. CONCLUSIONS: Many cases of tuberculosis are not notified (27%). Fourteen per cent of all sputum smear positive cases of tuberculosis were not notified, and these patients are a considerable public health risk. The true incidence of tuberculosis in the area studied is at least one third higher than current notification figures suggest.

Timeliness of notification in infectious disease cases.

Records of notification in cases of eight infectious diseases in the "Servei Territorial de Salut Publica" of the Province of Barcelona, Spain, between 1982 and 1986 were reviewed. Time from onset of symptoms to notification, time from notification to completion of data collection, and time from onset to completion of the case investigation were analyzed. For the period from onset to notification, the shortest mean was registered for meningococcal infection (6.31 days) and the longest was for pulmonary tuberculosis (54.79 days). For time from notification to complete investigation, the shortest value was for pulmonary tuberculosis (12.20 days) and the longest for rickettsioses (35.79 days). Time from onset to completion of data collection was 22.87 days for meningococcal infection and 72.34 days for tuberculosis of other organs (probably because of the long period of time that elapses between the onset of the first symptoms and notification). It would appear that both physicians and the general population must be educated so that lay-men can identify early signs and symptoms of disease and physicians can realize that statutory notification of infectious diseases is strongly linked to community health care.

Auditing and improving notification and chemoprophylaxis in bacterial meningitis.

STUDY OBJECTIVE: The aim was to audit, against agreed standards, the control of bacterial meningitis, in particular completeness of notification and appropriateness of distribution of chemoprophylaxis to contacts; and to implement appropriate changes and monitor their impact. DESIGN: The first phase involved determination, for the years 1983 and 1984, of completeness of notification by comparison with a comprehensive case register. Information about chemoprophylaxis was obtained from case notes, questionnaires to general practitioners and other records. The second phase involved introducing a programme of clinician education in the hospital with the poorest observed notification performance and re-examining performance during 1988. Districtwide education regarding chemoprophylaxis was undertaken and the situation re-examined in 1988. SETTING: The study took place in Mid Glamorgan Health Authority (population 536,000), with four acute hospitals. POPULATION: Consisted of all the residents of Mid Glamorgan Health Authority. MAIN RESULTS: During the first phase of the audit only 28 out of 79 cases of bacterial meningitis were notified (35%). Performance in one hospital was significantly worse than in the other three. Chemoprophylaxis was distributed to 20 out of 26 (77%) cases of meningococcal meningitis but inappropriate drugs were used in four cases and prophylaxis was distributed more widely than is recommended in 10 cases. In the phase 2 re-examination, a significant improvement in notification was observed in the hospital where special measures were taken, with no change in a "control" hospital. Chemoprophylaxis improved throughout the District, although rifampicin continued to be distributed too widely. CONCLUSIONS: As a result of this audit, measurable improvements in both infectious disease notification and chemoprophylaxis practice were obtained by the education of clinicians. The study provides a good example of a completed audit cycle in public health medicine.

Communicable Disease Control

[Evaluation of the information provided by the system of compulsory notification of diseases].

In order to assess activities of epidemiological surveillance resulting from the statutory notification system, a total of 17,394 notification records of eight infectious diseases (brucellosis, bacillary dysentery, typhoid fever, viral hepatitis, meningococcal infection, rickettsioses other than exanthematous typhus, pulmonary tuberculosis, and tuberculosis of other organs) together with 10,503 epidemiological surveys submitted to the "Servei Territorial de Salut Pública" of the province of Barcelona between 1982 and 1986 were reviewed. In notification records, data to locate physicians were the most commonly found (between 92.6% and 99.4% according to disease), whereas in epidemiological surveys, clinical and analytical data were the most frequently encountered. The inclusion of data of epidemiological interest ranged from 3.6 to 68.6%. In order to improve efficacy of the statutory notification system a proposal is made to reduce the extension of epidemiological surveys in terms of requesting only necessary data to establish appropriate measures in each case.

A survey of hepatitis B surface antigen-positive blood donors: degree of understanding and action taken after notification.

All blood donors in the United States are tested for hepatitis B surface antigen (HBsAg) upon donation; if the test result is positive, the primary method of notification is by letter. To assess the effectiveness of this notification methods in stimulating HBsAg-positive donors to seek medical care and take preventive measures, 54 donors who tested HBsAg-positive on donation at the American Red Cross Blood Services. Atlanta Region, from January 1987 to July 1989 were interviewed. Thirty-nine donors (72%) had sought medical care after notification; the only motivating factor was that the letter told the donor to consult with his or her physician. Compared with donors who did not seek medical care, donors who did so were more likely to understand that the blood test was abnormal or that they were infected, and they were more likely to understand how hepatitis B virus is transmitted and that a vaccine is available. The differences were not significant, however. Of those donors who sought medical care, less than half received appropriate recommendations for protection of contacts, and of those who did, only one-third received prophylaxis. In-person and telephone interviews with donors, revision of the notification letter, and hepatitis B education programs targeted at medical care providers are suggested.

Under-reporting in hepatitis B notifications.

Notification and laboratory data for the period January 1985-December 1988 were compared in order to estimate: (i) the minimum level of under-reporting of hepatitis B; and (ii) the consistency of the level of under-reporting, both regionally and nationally. Ratios between hepatitis B notifications and positive hepatitis B laboratory tests (reporting ratios) were calculated to quantify the discrepancy between these parameters. There were at least 7 positive hepatitis B laboratory results for each notified case of hepatitis B during each year studied. The differences between the national reporting ratios for each of the study years were small, indicating that nationally the level of reporting of hepatitis B is fairly consistent. The Cape region had the highest and most constant level of hepatitis B reporting compared with other regions. We conclude that the national incidence of hepatitis B is at least 7 times higher than that calculated from notification data. Further, the inter-year analysis of hepatitis B notification data to identify trends nationally and within the Cape region is valid. However, caution is called for when comparing the incidence rates between regions due to inter-region and region-specific inter-year inconsistencies in reporting levels.

Exercise intervention attenuates emotional distress and natural killer cell decrements following notification of positive serologic status for HIV-1.

The impact of aerobic exercise training as a buffer of the affective distress and immune decrements which accompany the notification of HIV-1 antibody status in an AIDS risk group was studied. Fifty asymptomatic gay males with a pretraining fitness level of average or below (determined by predicted VO2 max) were randomly assigned to either an aerobic exercise training program or a no-contact control condition. After five weeks of training, at a point 72 hours before serostatus notification, psychometric, fitness and immunologic data were collected on all subjects. Psychometric and immunologic measures were again collected one-week postnotification. Seropositive controls showed significant increases in anxiety and depression, as well as decrements in natural killer cell number following notification whereas, seropositive exercisers showed no similar changes and in fact, resembled both seronegative groups. These findings suggest that concurrent changes in some affective and immunologic measures in response to an acute stressor might be attenuated by an experimentally manipulated aerobic exercise training intervention.

Limitations of the OPCS congenital malformation notification system illustrated by examination of congenital malformations of the cardiovascular system in districts within the Trent Region.

Data are presented from OPCS notification statistics and other sources on rates of congenital cardiovascular malformations in the Trent Health Region and in its constituent Districts. While Trent in general, and some of its districts in particular, show high notification rates, other data sources suggest that the underlying malformation rate may not be raised compared with that seen nationally. Reasons for this discrepancy are discussed and the OPCS notification system is compared with that in Scotland.

Results of a randomized trial of partner notification in cases of HIV infection in North Carolina.

BACKGROUND: We sought to compare two methods of notifying sex partners of subjects infected with the human immunodeficiency virus (HIV) or persons who had shared needles with them (needle-sharing partners): "patient referral," in which the responsibility for notifying partners was left to the patient, and "provider referral," in which providers attempted to notify partners. METHODS: Names of sex partners and needle-sharing partners and information on how to locate them were obtained from consenting HIV-infected subjects identified in the HIV-testing programs at three public health departments in North Carolina. The subjects were randomly assigned to a patient-referral group (in which patients had the initial responsibility for notifying their partners) or a provider-referral group (in which the study counselor notified the partners). The success of attempts to notify partners was monitored by means of interviews with counselors conducted both in the field and at the health department. RESULTS: Of 534 HIV-positive persons identified at the health departments, 247 (46 percent) did not return for counseling after the test, 8 were counseled outside the study, and 117 (22 percent) were ineligible. Of the 162 invited to participate, 88 (54 percent) declined and 74 (46 percent) agreed. The subjects were mostly male (69 percent), black (87 percent), homosexual or bisexual (76 percent of the men), and had a median age of 30 years. Thirty-nine were assigned to the provider-referral group and 35 to the patient-referral group. In the provider-referral group 78 of 157 partners (50 percent) were successfully notified, whereas in the patient-referral group only 10 of 153 (7 percent) were notified. Of the partners notified by the counselors, 94 percent were not aware that they had been exposed to HIV. Overall, 23 percent of the partners notified and tested were HIV-positive. CONCLUSIONS: In this trial, leaving the notification of partners up to the subjects (patient referral) was quite ineffective, despite the North Carolina law requiring that partners be notified. Partner notification by public health counselors (provider referral) was significantly more effective. Although the effectiveness of notification procedures is constrained by the accuracy of the information provided by HIV-infected patients, counselors who notify the partners of an infected patient can refer them to educational, medical, and support services targeted to persons at high risk for HIV infection and may encourage the adoption of less risky behavior.

Partner notification as a tool for research in HIV epidemiology: behaviour change, transmission risk and incidence trends.

OBJECTIVE: To assess whether routinely collected data from partner notification for HIV infection could be used to study HIV epidemiology. The issues addressed were measures of contact patterns and behaviour change, variables influencing transmission risks, and indications of HIV incidence. DESIGN: We collected anonymous questionnaire data from all partner notifications performed from seropositive patients diagnosed in Sweden between 1 January 1989 and 30 June 1990. METHOD: A structured questionnaire was completed by the physician or counsellor interviewing newly diagnosed seropositive patients and counselling their reported partners. The questions focused on temporal and behavioural aspects of all contacts between index patients and partners. RESULTS: Questionnaires were completed for 365 of the 403 (91%) index patients diagnosed during the study period, for 350 of the 390 (90%) located partners, and for 274 of the 297 (92%) relationships where results of HIV testing were known for index patient and partner. Seropositive individuals diagnosed in 1989 or later reported less risk behaviour than those diagnosed earlier. Risk of transmission in sexual contact increased when the infectious partner developed symptoms of HIV infection. Anal intercourse was found to be approximately twice as infectious as vaginal, and transmission risk from a seropositive insertive partner approximately twice as high as from a receptive. The total HIV incidence in Sweden appears to be declining, as does the number of newly diagnosed infected homosexual men. CONCLUSION: Carefully collected data acquired from a partner notification programme are well suited to describe and follow the epidemiology of HIV infection.

Partner notification and the control of human immunodeficiency virus infection. Two years of experience in San Francisco.

To evaluate partner notification of opposite-sex sexual partners of AIDS patients as a means of limiting sexual and vertical transmission of human immunodeficiency virus (HIV), the authors examined the first 27 months of their experience with partner notification. Overall, of 145 AIDS patients eligible to participate, 51 (35%) were interviewed and identified 135 opposite-sex sexual partners. Of the 135 partners, 59 (44%) were interviewed and 34 (25%) were tested, resulting in the diagnosis of 7 (5%) HIV-infected partners. Refusal rates for index patients and partners were low (9% and 12%, respectively). Costs for the program were $454 per partner interviewed and $2,203 per seropositive partners identified. The authors conclude that although partner notification is more expensive than more widely targeted AIDS prevention and education efforts, its ability to target case finding, education, and counseling to women at highest risk of infection makes it potentially cost-effective for prevention of vertically transmitted HIV infection.

National survey of notifications of tuberculosis in England and Wales in 1988. Medical Research Council Cardiothoracic Epidemiology Group.

BACKGROUND: A survey was undertaken to determine the distribution of tuberculosis in England and Wales and, by comparison with the findings of similar surveys in 1978-9 and 1983, to study trends in the incidence of the disease by ethnic group over the decade. METHODS: The survey included all cases of tuberculosis in England and Wales newly notified to the medical officers for environmental health during the six months from 2 January to 1 July 1988. Notification rates were calculated from population estimates from the 1988 Labour Force Survey. RESULTS: Clinical details were obtained from the clinician for 2149 (99.4%) of the 2163 newly notified and previously untreated patients. Over 90% were either white (53%) or of Indian, Pakistani, or Bangladeshi ethnic origin (39%). The notification rate in the white population was 4.7/100,000/year, a decline of 7.2% per year since 1978. The rate was 134.6/100,000/year in the population of Indian ethnic origin, and 100.5/100,000/year in that of Pakistani or Bangladeshi ethnic origin, a decline of 6% a year since 1978 for the two groups combined (standardised for age, country of birth, and length of time in the UK). In all ethnic groups rates of disease were much higher in the elderly than in the young. Bacteriological results were available in 1161 (80%) of the 1443 pulmonary cases. In 939 (81%) Mycobacterium tuberculosis was cultured; 614 cases (53%) also had positive smears, of which 424 (69%) were from white patients. CONCLUSIONS: Notification rates for tuberculosis in England and Wales declined over the decade, but major differences remained between ethnic groups.

Partner notification and patient education for cases of Chlamydia trachomatis infection in a rural Nova Scotia health unit.

From September 1990 to March 1991, 47 of 52 patients with genital C. trachomatis infections in a rural health unit in Nova Scotia were interviewed about preventive education by physicians partner notification, past history, and treatment. Seventy-six percent of those with partners of the previous month were instructed by physicians to notify these partners. Twenty-five of 37 partners were notified. Of those not notified, 83% could have been reached. Reasons for cases not notifying partners included not being informed of test results, embarrassment, and not considering notification important. Fifty-two percent of cases were advised to practise safer sex; this was generally limited to advice to use condoms. Twenty-three percent had had a previous sexually transmitted disease. Treatment was appropriate in all cases where it could be determined. More preventive education by physicians and public health involvement in partner notification for such patients are required.

Partner acceptance of health department notification of HIV exposure, South Carolina.

To determine the acceptability of health department notification of sex and needle-sharing partners of persons infected with human immunodeficiency virus (HIV), we administered an anonymous questionnaire to partners notified of their exposure to HIV during the previous 2 years. Of the 202 partners notified, 132 (65%) were locatable and completed the questionnaire. Only 12 (9%) thought they may have been exposed to HIV before health department notification. When the 132 partners were asked if they thought the health department did the right thing in telling them about their exposure, 87% responded "yes;" when asked if the health department should keep notifying persons exposed to HIV, 92% responded "yes." Responses were similar for homosexual-bisexual men, heterosexuals, and intravenous drug users; men and women; and whites and blacks. We conclude that health department notification is acceptable to persons exposed to HIV in this rural South Carolina district.

Impact of the Minnesota Parental Notification Law on abortion and birth.

BACKGROUND: The impact of the Minnesota Parental Notification Law on abortion and birth was examined. METHODS: Using linear models, outcome parameters were compared before and after enactment of the law. Time by age group interactions also were examined. RESULTS: The pre-enactment to post-enactment change in the Minnesota abortion rate reflected a greater decline for minors (less than or equal to 17 years old) than for 18-19 year-olds (who were not under the law). An increase in abortion rate occurred for women ages 20-44. The law appeared to have had no impact on birth rate in minors. Following the enactment of the law, the rate of early abortions (less than or equal to 12 weeks) declined among minors more than the rate of late abortions (greater than 12 weeks). This resulted in a pre-enactment to post-enactment increase in the ratio of late-to-early abortions among minors. CONCLUSIONS: These data suggest that parental notification facilitated pregnancy avoidance in 15-17 year-old Minnesota women. Abortion rates declined unexpectedly while birth rates continued to decline in accordance with a long-term trend.
