This is a qualitative study, which aims at analyzing the organization of Epidemiological Vigilance (EV) in the local health system of Feira de Santana-BA, from 1997 to 2001 > in this study the following aspects were considered: organizational structure, resources available (human and material ones), planning, execution, intra and interinstitutional and intersectional articulations, considering the insertion of the city in the "Basic assistance Program". The collection of data was carried out in 3 stages: documental analysis, semi-structured interviews and direct observation with the VE. team. Results revealed that there are frequent changes in the management positions of VE. The structure, centralized in the SMS, prioritizes programmatic actions which are not articulated to the network of services offered. Advances can be noticed in the infrastructure, despite the lack of equipment and the deficiency in the qualification the human resources. The transformation of the model of health assistance is possible if health professionals, managers and users have political interest in changing it the practices in health services. 相似文献

OBJECTIVE: To analyze the clinical-epidemiological profile and in-hospital death predictors of infectious meningitis patients admitted to a public hospital. METHODS: There were studied 694 cases of meningitis notified and investigated by a public hospital's epidemiology service from 1986 to 2002, using the National Information System of Notifiable Diseases (SINAN) as part of the local routine of epidemiologic surveillance. Statistics analysis included multivariate logistic regression. RESULTS: The most frequent etiologies were: cryptococcal (12.3%; case-fatality =37.7%); meningococcal (8.7%; fatality =13.3%); pneumococcal (7.2%; fatality =46%); tuberculous (6.1%; fatality =40.5%); staphylococcal (5.2%; fatality =38.9%), viral (5.5%; fatality =7.9%); Haemophilus (2.9%; fatality =20%). The proportion of cases of non-specified etiology was 38.8% (fatality =36%) and 17.3% were associated to HIV infection. It was found that 27.1% were nosocomial meningitis and 9.2% of the surviving cases had sequelae. The logistic regression model identified the following death predictors of infectious meningitis: etiology (reference: viral category) -- tuberculous, cryptococcal, staphylococcal, meningococcal, non-specified, other Gram-negative, Candida and pneumococcal; HIV co-infection; coma. Fever, vomiting and neck stiffness were associated to a lower odds of death. CONCLUSIONS: The high proportion of non-specified etiology and high case-fatality may reflect problems in the hospital care process and/or case selection. The epidemiologic surveillance system operating at the hospital level was able to feedback the services with clinical indicators. The use of SINAN at the local level was considered useful and pertinent. 相似文献

Violence prevention policies should be based on information, follow-up, research, and analysis, all of which increase the chances of success and make it easier to evaluate interventions. This implies, in turn, that there is a need to create surveillance, research, and prevention models for violence within the sphere of public health and epidemiology, a task that constitutes an integral part of the Pan American Health Organization's Regional Plan of Action Health and Violence. This article describes the objectives of epidemiologic surveillance systems and explains their purpose and scope, along with the barriers that stand in the way of their implementation. It also examines a number of variables and their definitions, the types of analyses and reports that should be generated, and the decisions that can be made on the basis of these reports. Finally, it discusses ethical criteria and describes the experiences of the program known as Desarrollo, Seguridad y Paz (DESEPAZ) in Cali and Santa Fe de Bogota, Colombia, where an epidemiologic surveillance system against violence has been implemented. 相似文献

BACKGROUND: The Italian National Mesothelioma Registry (ReNaM) was set up at the National Institute for Occupational Safety and Health (ISPESL) to estimate Italian incidence of malignant mesothelioma (MM), define modalities of asbestos exposures, assess impact and diffusion of MM, identify underestimated sources of environmental contamination. OBJECTIVES: To describe ReNaM activity, database dimension and epidemiological characteristics of the caselist. METHODS: Regional Operating Centers (COR) in 16 Italian regions were set up to identify and investigate all cases of MM diagnosed in each region, applying national guidelines. COR collect cases in health care institutions. Occupational history, lifestyle and residence are obtained by direct interview using a standard questionnaire. Exposure modalities are classified by industrial hygienists, evaluating whether work, private life or any particular environmental condition could have involved asbestos exposure. RESULTS: Data refer to 3,446 cases collected in 9 Italian regions during 1993-2001. Pleural mesothelioma affected 94% cases, pleural/peritoneal ratio was 16:1. Gender ratio (M/F) was 2.7:1 (1.3:1 for peritoneum). There was a variety of occupational exposures, some already known as high risk sectors and others unexpected. The most common exposures occurred in building and construction, metallurgy and steel, shipbuilding, and railway stock. High risk categories were encountered such as bricklayers, plumbers, carpenters, electricians, welders, installers and maintenance workers in metallurgy and the steel industry, general labourers, tool makers and painters in shipbuilding/repair/demolition. CONCLUSIONS: Despite some ReNam's limitations, identification of MM cases and analysis of modality of exposure, with standardized criteria, are a fundamental tool for primary prevention of asbestos related diseases. 相似文献

AIMS: To use the data set of the Hungarian Case-Control Surveillance of Congenital Abnormalities (HCCSCA) for the evaluation of birth outcomes beyond congenital abnormalities and to show as example the study of 49 antimicrobial drugs used in Hungary for the reduction of preterm births. METHODS: The population-based data set of the Hungarian Case-Control Surveillance of Congenital Abnormalities, 1980-1996, included 38,151 newborn infants without birth defects and this sample represented 1.8% of Hungarian births. Medically recorded gestational age at delivery and birthweight, in addition the rate of preterm births and low birthweight newborns born to mothers with or without different antimicrobial drugs used at least by ten pregnant women were analysed. RESULTS: Of 49 antimicrobial drugs, two: ampicillin (adjusted POR with 95% CI: 0.8, 0.7-0.9) and clotrimazole (0.8, 0.7-0.9) showed a preterm birth preventive effect. This preterm preventive effect was found mainly after the use of ampicillin and clotrimazole during the first trimester of pregnancy. CONCLUSIONS: Ampicillin and clotrimazole may be effective for the reduction of preterm births due to infectious diseases of pregnant women in general but particularly caused by genital infections. However, the limitation of the data set did not allow the appropriate evaluation of some antimicrobial drugs (e.g. clindamycin). 相似文献

Limb developmental defects are well-known, conspicuous abnormalities. Until this day, the background has still not been completely revealed, however, the development of scientific methods provides more and more opportunities which may help to understand developmental processes and defects of this compound system. Considering these aspects, following data collection from patients with limb developmental defects, we began a study with the purpose of finding/establishing a classification system that is suitable for morphological and clinical distinctions, besides considering developmental aspects, and may help to indicate adequate genetic examinations. To classify 195 patients included in our database, we chose a worldwide accepted table from Swanson. Based upon our observations we proposed some alterations, which finally lead to a table, suitable for patient classification based upon morphology and clinical features. Furthermore it allows comparisons concerning developmental aspects, gives reasonable background for genetic studies and is suitable for everyday clinical usage. 相似文献

On surveillance methods for congenital malformations 总被引:1,自引:0,他引:1
This paper presents an 'optimal' procedure for the use of the 'sets' method, a system proposed for surveillance of congenital malformations. Comparisons over a number of examples shows that the given procedure represents a clear improvement over the one originally proposed, and, in some conditions, is more efficient than the cusum scheme. 相似文献

Evaluation of the impact of Chernobyl on the prevalence of congenital anomalies in 16 regions of Europe. EUROCAT Working Group 总被引:1,自引:0,他引:1
BACKGROUND: Surveillance data from population-based congenital anomaly registers in 16 regions of Europe (mainly Western Europe) were analysed to assess the impact of the Chernobyl accident on the prevalence of selected congenital anomalies. METHODS: Three cohorts of pregnancies were defined: those exposed during the first month following Chernobyl (External Exposure Cohort), the first year (Total Exposure Cohort) and the two subsequent years (Control Cohort). Expected numbers of congenital anomalies in these cohorts were calculated from 1980-1985 baseline rates. Registries were grouped into three exposure categories according to first-year exposure estimates. RESULTS: There was no overall or dose-related increase in prevalence in the two exposed cohorts for Down's Syndrome, neural tube defects, other central nervous system defects or eye defects. There was a statistically significant overall 22% (95% CI: 13-31%) excess of Down's Syndrome in the Control Cohort, with no dose-response relationship. CONCLUSIONS: Chernobyl had no detectable impact on the prevalence of congenital anomalies in Western Europe, suggesting that in retrospect the widespread fear in the population about the possible effects of exposure on the unborn fetus was not justified. An increasing prevalence of Down's Syndrome in the 1980s, probably unrelated to Chernobyl, merits further investigation. 相似文献

The Epidemiologic Surveillance Project: a computer-based system for disease surveillance 总被引:1,自引:0,他引:1
The Epidemiologic Surveillance Project (ESP) is a computer-based surveillance system for the rapid transmission and analysis of national morbidity data. These data are transmitted weekly by state health department computers to the Centers for Disease Control (CDC), using a commercial electronic mail facility (MINET). Participating state health departments transmit data through existing computer systems using a standard record and data transmission protocol. State and national data are rapidly analyzed at the CDC, and reports of these analyses are transmitted through MINET to the states. Maps based on these data and other tabular displays of demographic and epidemiologic characteristics of the diseases being tracked are periodically prepared and distributed. Because the efficiency, speed, and uniformity of tabulation of this system are greater than those of systems that use protocol and telephonic reports of case totals, the ESP may be a model for future surveillance systems. 相似文献

In order to compare the birth incidences of particular congenital abnormalities in different populations, it is often necessary to allow for the effects of maternal age. Three age-adjusted indices are defined, based on analogous indices from the literature on mortality studies, namely, the Standardized Mortality Ratio, the Comparative Mortality Figure and Kerridge's Inverse Method. In most practical situations the differences between them are likely to be trival. However, the first index is maximally efficient under multiplicative risk models and is easily adjusted for incomplete data. The second is the only one to provide valid comparisons under additive, as well as multiplicative, models. The third has the advantage that it does not require a knowledge of the maternal age distribution of all births in the population. The use of the three indices is illustrated with published data on Down's syndrome. 相似文献
