Notification of TB cases was introduced since 1947 in Japan, and statistics on notified TB cases by sex and age groups was available since 1949. Sex and age specific TB notification rates per 100,000 from 1949 to 2001 were tabulated together with the number of notified TB cases since 1969.
The notification of food poisoning is a statutory obligation of medical practitioners in the United Kingdom. Its objectives and methods are vague and ill documented, and the value of its output doubtful. Statutory notification of food poisoning is poor at identifying outbreaks, or single cases of severe disease, or as a measure of longer term trends. It should be fundamentally reformed.
Collaborating neurologists provided a central office with clinical information, driving experience and accident rates in all drivers they counselled after diagnosing seizures or other unexplained episodes of loss of consciousness. Each patient received and was asked to return a notification slip to DVLA. Of 638 patients counselled, 11% had been involved as a driver in a road traffic accident in the previous year. Six patients had been involved in an accident producing serious injury. These estimates do not differ from those expected in a population of non-epileptic drivers with the same age and sex distribution. Of patients counselled, 27.1% returned a reply slip to the DVLA. Notification was more likely if the patient was aged 50 or over at the time of counselling, if the counselling was undertaken by a consultant, if an accident had occurred in the previous year and if the subject had also been advised to start or was already taking anti-epileptic drugs. Patients counselled after a single seizure were more likely to notify than those with a diagnosis of epilepsy.
There is a paucity of data on pesticide-related morbidity and mortality in South Africa. A review of notifications to the western Cape office of the Department of National Health and Population Development from 1987 to 1991 was undertaken to describe the epidemiological profile of pesticide poisoning in the region. Two hundred and twenty-five cases of pesticide poisoning were identified, of which the majority were from rural areas. Farmers, farm workers and their families were most frequently involved in poisoning events, which included accidents arising outside of workplace production (44%), self-inflicted injury (35%) and direct occupational contamination (11%). Farm pesticide stores were the most frequent source of pesticide and a seasonal variation in the trend of poisoning events could be discerned; this corresponded to agricultural spraying practices in the region. The mortality rate was significantly higher among those with self-inflicted injury, particularly farm workers. A concurrent review of hospital admissions for 1991 found that 78% of cases had not been notified. In view of the key role of surveillance in reducing pesticide-related morbidity and mortality, a call is made to improve notification of pesticide poisoning so as to facilitate control of an important potential public health problem.
Advantages and setbacks of the existing Swiss disease notification system are reviewed. The public takes interest in the notification data output. The voluntary sentinels provide useful early warning. Currently, 60 conditions are notifiable. It is intended to lower this number to < 30. Other measures to upgrade the system include annual review and publication of an updated list of notifiable diseases, limitation to an essential core of parameters collected from physicians on initial and follow-up questionnaires, and practical advice on diagnostic and control measures provided for in questionnaires for the infectious disease under query.
The concept of worker notification has evolved over the years to a prevailing view that workers should be notified of all epidemiologic studies that make use of their medical information. To adequately communicate health information to workers, epidemiologists must consider the intended audience along with its need for risk information that is scientifically valid and clearly outlines areas of uncertainty. This goal is facilitated by full disclosure to workers of information pertinent to the planning, conduct, and interpretation of research efforts. Subjectivity in choosing unanticipated research findings for inclusion in worker notifications may permit bias toward a personal viewpoint, but this can be minimized by prestudy agreement on appropriate criteria for selecting which research findings to communicate. Epidemiologic theory and principles of causal inference should guide the development of appropriate criteria. The timeliness of worker communications has received limited attention, and workers have often been the "last to know" about important studies. This may influence workers' receptivity to the risk message. Sponsoring organizations should ensure that an acceptable communications plan is included in research protocols and that the plan accords priority to notifying workers about study results.
This study, based on 169 telephone interviews, explores how a sample of chromium-exposed workers responded to notification of their cohort's elevated risk of lung cancer. It is important to recognize that notified workers do not react as isolated individuals. Their responses are social, actively constructed through interaction with others, unfolding over time within a context of relationships and shared symbols that mediate the risk information. This report illustrates some of the ways that socially-based beliefs and interaction with the social environment can influence worker response, and suggests a more sociologically sophisticated concept of notification to fit the realities of workers' lives.
The Drake Chemical Workers' Health Registry combined notification of workers about bladder cancer risk with access to a free program for screening and diagnosis. Evaluation of the project has given rise to several findings and new research questions. Findings in this article illustrate the following evaluation issues: 1) studying the combination of strategies that are most effective and cost effective to notify workers of their disease risks, 2) determining the realistic yield from strategies to gain participation in health screening and other protective services for notified workers, 3) identifying the notification strategies that were most effective for different kinds of participants, 4) using process evaluation to identify key activities for ensuring continued participation of cohort members in screening, and 5) examining the extent to which participants are willing to quit smoking to protect their health.
BACKGROUND: Recent progress in predictive techniques allows people at risk of developing type 1 diabetes to be identified in a pre-symptomatic stage and prevention trials to be implemented. The present study examined prospectively whether participants in a screening programme anticipated behavioural changes in the event of having a high risk. METHODS: Four hundred and three first-degree relatives of people with type 1 diabetes completed a self-administered questionnaire about their views on screening and diabetes, and questionnaires on well-being and locus of control. RESULTS: Prior to risk notification, 73% reported that they intended to introduce lifestyle changes if at high risk. The vast majority of the respondents (87%) reported that eating habits would be the main changes made. Those anticipating changes believed they could take actions to reduce their risk of type 1 diabetes (p<0.001) and to have personal control over diabetes onset (p<0.001). They were also more worried about developing diabetes (p<0.01) and preoccupied with diabetes-related symptoms (p<0.01). CONCLUSIONS: Prior to risk notification, the process of being screened raised concerns and expectations about future changes. Despite the lack of any evidence, people believed lifestyle changes would be effective in reducing their risk. Since the impact of lifestyle in the development of type 1 diabetes is not yet established, accurate information about the role of health behaviour in the progression to overt diabetes is needed to avoid unrealistic expectations on the benefit of these changes and unnecessary impairment to quality of life. Personally initiated changes should be monitored since they could importantly influence the progress and outcome of prevention trials.
BACKGROUND: This study aimed to determine women's knowledge of their Pap test results and predictors of accurate knowledge, adherence to follow-up recommendations for abnormal results, current methods of notifying women about their Pap test results, women's preferences for notification method, and women's satisfaction with the current notification system. METHOD: A telephone survey was undertaken of 315 women with a recent normal or abnormal Pap test result, drawn from pathology records in Sydney, Australia. RESULTS: Findings revealed that 61% of women with a normal result and 93% of women with an abnormal result self reported having been notified about their result. According to women's reports, 7% of those with abnormal results had not been notified and a further 11% of women with abnormal results were unaware that their result was abnormal, giving a total of 18% of abnormal results not communicated adequately to women. Self-reported adherence with follow-up recommendations among women with an abnormal result was less than optimal. The most common methods of notifying women of their results were initiated by the women such as the woman phoning the doctor or receptionist. However, women strongly preferred doctor-initiated methods, such as a written record from the doctor, the doctor phoning the woman, or consultation with the doctor. CONCLUSION: Results suggest that better methods of notifying and educating women about their Pap test results are necessary to improve women's knowledge and satisfaction and, even more importantly, to improve their level of adherence with follow-up recommendations for abnormal results.
Exposures to measles in medical settings have contributed to the recent resurgence of the disease in the United States. Following a measles exposure in two pediatric medical facilities serving an inner-city population, we investigated the effectiveness of a disease notification strategy and compliance of the exposed population with recommendations for post-exposure prophylaxis, two requirements of a successful intervention program. Of 106 families with children eligible for a prophylactic vaccination by standard guidelines, 64% were notified of exposure by telephone. Compliance was assessed by a brief telephone questionnaire based upon the Health Belief Model, and verified by medical records. Forty-six families were interviewed regarding their decisions to comply with the recommendations. Most (75%) families were compliant. Compliant parents perceived measles to be severe and their children to be in excellent health. In a multiple logistic regression analysis, only the perceived severity of measles significantly contributed to the model. We conclude that: infection control outreach may need to extend beyond telephone notification for an inner-city population, and that once notified, most people will comply with recommendations. The Health Belief Model explains compliance with infection control measures and may be useful in guiding public health interventions.
The number of newly notified, previously untreated patients in a survey of notifications of tuberculosis in England and Wales conducted by the MRC in 1983 was 26% lower than in the previous MRC survey in 1978/79. In both surveys the great majority of patients were of White (about half) or Indian subcontinent (Indian, Pakistani or Bangladeshi) ethnic origin (just over a third). The notification rates in the Indian subcontinent (ISC) ethnic groups were much higher than for the White group and were highest in those most recently arrived in the UK. There were a number of differences in the findings for the White and the ISC ethnic groups. Nearly two-thirds of the White patients but less than half of the ISC patients were male and the White patients were, on average, older, about half aged 55 years or more compared with 14% of the ISC patients. Respiratory disease occurred in 82% of the White patients compared with 66% of the ISC patients. Radiographically, at independent assessment, more of the White patients had pulmonary lesions, 88% compared with 63% and these were, on average, more extensive and cavitated than in the ISC patients. Isolated mediastinal lymphadenopathy, however, was more common in the ISC patients. The diagnosis was confirmed bacteriologically on culture of a respiratory specimen in a higher proportion of the White than the ISC patients (65% and 41% respectively) and more were positive on smear as well (45% and 25% respectively). The level of initial drug resistance was lower in the White patients: only 10 (1.6%) of the 623 strains tested were resistant compared to 23 (12.8%) of the 179 from ISC patients. In both White and ISC ethnic groups the commonest non-respiratory lesion was peripheral lymph node involvement, namely 37% of the 369 White and 53% of the 503 ISC patients with non-respiratory disease. The diagnosis was confirmed by bacteriological examination of the lymph node in 47% of the ISC patients compared with 29% of the White patients with a lesion. Bone or joint disease occurred in 11% of the White and 20% of the ISC patients; the commonest site in both groups was the spine. Genitourinary disease was present in 98 (27%) of White and 24 (5%) of ISC patients with a non-respiratory lesion. There were 61 patients with tuberculosis involving the central nervous system, including 55 with meningitis, the proportions being similar for the White and the ISC ethnic groups, 7% and 5% respectively.
Since 1985, partner notification has been part of Swedish policy to prevent the spread of human immunodeficiency virus (HIV) infection. Potentially infected partners of a newly diagnosed seropositive patient are notified either by the index patient or by the physician and referred for counselling. The efficacy of this strategy was assessed over 18 months in 1989-90. 365 HIV-seropositive index patients (91% of the 403 patients diagnosed in Sweden during the study period) reported 564 sexual or needle-sharing contacts. 390 contacts were located and counselled and HIV test results are known for 350 of them. In 53 of the 350 cases, previously unknown seropositivity was diagnosed. Partner notification for HIV should be viewed as a strategy to offer counselling and testing to a high-prevalence group of people. In a country where general HIV prevalence is low, the strategy is cost-effective for location and counselling of unknowingly seropositive individuals.
The use of an automated collision notification (ACN) device in vehicles can greatly reduce the time between crash occurrence and notification of emergency medical services (EMSs). Most ACN devices rely on cellular technology to report important crash information to the proper authorities. The objective of this study was to examine the ability of the existing western New York cellular analog system to support ACN systems. The first task was to develop a model predicting the probability of successfully completing an emergency ACN call at attenuated levels of received signal strength indicator (RSSI), a measurement of the bond between cell phone and tower. Then, empirical estimates were made of the time necessary for call completion at given levels of the RSSI. The RSSI is sampled at locations throughout Erie County, New York, and this information is used to determine the probability of successful call completion for different locations within the county. This model was then applied to historic data for selected past crashes. Finally, the findings were compared with real-world crash data obtained from the ACN Field Operational Test program, where 750 ACN devices were installed in cars and their performance examined over time. An interpolated map of the sampled RSSI values suggests that cellular coverage in Erie County is adequate to support the automated collision network technology. The models and techniques described here are applicable to other areas and regions of the country.
We reviewed procedures for and data about patient notification of the suspension of the treatment protocol for four clinical trials. We also examined how data collected after the suspensions were used. All four trials were designed to evaluate treatments for cytomegalovirus retinitis in patients with AIDS and were conducted by the Studies of Ocular Complications of AIDS Research Group. Documentation that patients were notified of the results varied from 62--100% with three of the four studies documenting the process for > or =92% of patients. The median time between the recommendation for protocol suspension and patient notification varied from 7--49 days with three of the four trials at 12 days or fewer. Most of the analyses of data collected after the suspension of the treatment protocol did not focus on comparisons among treatment groups. Although they provided useful information about the long-term outcomes and the nature of the disease, they did not alter the conclusions about safety and efficacy from the randomized portion of the trial.

Restrictions have been placed on the ability of adolescents to obtain human immunodeficiency virus (HIV) testing independent of their parents. Although some states have given adolescents the right to consent to HIV testing independently, many states have remained silent on the issue or have compromised these rights by providing for parental consent or notification when adolescents seek testing. This article examines existing policies and explores whether policies that require adolescents to obtain parental consent, or that permit or mandate parental notification, may deter them from obtaining needed HIV testing.
STUDY OBJECTIVE: To understand the communication process involved in the patient-self referral method among adolescent females with chlamydia and gonococcal infection. DESIGN: A cross-sectional descriptive study using a convenience sample was conducted in 54 predominantly African-American females, 13 to 20 years-old, with gonococcal and/or chlamydia cervicitis at an urban hospital based reproductive health clinic. Subjects interviewed at their treatment visit were asked what method of notification they used to tell their partner(s). Subjects who had not notified their partner were asked about their intended communication method and what they envisioned they would say to their partner. Coding methodology was used to analyze the information. In addition to qualitative information, outcome measures were the proportion of subjects who notified their partner(s), their communication method, style, and barriers to communication. RESULTS: According to the treatment visit, 57% (31/54) of subjects reported notifying their partner. Most had notified their partner by phone or face-to-face, stated basic facts about the infection, and used a "direct" and "sensitive" communication style. Of the subjects who had not notified their partner (23/54), several barriers to notification were reported, but 82% said they intend to notify their partner(s). CONCLUSIONS: Strategies to promote the patient-self referral method among young women who do not notify their partner(s) need further assessment.
Few data are available on the accuracy of death classification in patients with end-stage renal disease (ESRD). The National Institutes of Health-funded Hemodialysis (HEMO) Study allows the opportunity to compare cause of death recorded on the Health Care Financing Administration (HCFA) Death Notification Form 2746 with death classified by the HEMO Study. The HEMO Study cause of death is determined by trained HEMO Study Outcome Review Committee physicians. In this interim analysis, there were 220 deaths coded by both classification systems. Using the HEMO Study classification system, the most common cause of death was ischemic heart disease (20.4%), followed by arrhythmia and conduction problems (10.4%), cerebrovascular disease (8.6%), and non-access-related infections (7.7%). Using the HEMO Study final death classification as the reference standard, most differences in the two classification systems were related to coding of heart disease. Sensitivity for the HCFA classification ranged from 9.1% for congestive heart failure to 91.7% for malignancy, whereas specificity values were all greater than 78%. Positive predictive values ranged from 11.8% for other heart disease and conditions to 100% for malignancy and hepatobiliary disease, whereas negative predictive values were all greater than 85%. The kappa statistic between the two death classification systems ranged from 0.12 for congestive heart failure to 0.95 for malignancy. Studies using death classification from the HCFA ESRD death notification form for deaths secondary to either cardiovascular diseases or unknown causes should be interpreted cautiously.
