Information system of infectious diseases (IS IN)

Information systems of Institutions Protecting Public Health

PURPOSE OF DETECTION OF REQUESTED DATA

The purpose of investigation is to obtain information on incidence of infectious diseases for assessment of the evolution of the epidemiological situation on the CR territory, for monitoring of the health status of the population and for management of provision of health care.

For efficient management of mandatory notifications, registration and analysis of incidence of infections, in 1991 a new EPIDAT software was developed, building on the earlier information system of contagious diseases (ISPO). Since 1993, EPIDAT is is used nationwide in all public health stations as the basis of local, regional and national surveillance of infectious diseases.

STATISTICAL UNIT OF INVESTIGATION

Statistical units are all reported cases of disease from a list of selected serious infections; notifications concern verified cases, suspected diseases, carriage and deaths. Individual cases are statistically monitored according to ICD-10. Several serious infections are not monitored in this system but in separate individual information systems and registers. It concerns tuberculosis (dg. A15–A19), infections prevalently transferred by sexual intercourse (dg. A50–A64) and infection by human immunodeficiency virus (HIV, dg. B20–B24). Separate information systems are also established for acute respiratory infections (ARI) and influenza-like infections (ILI). A fully independent set of problems is monitored in Register of nosocomial infections. The EPIDAT system further monitors certain diseases listed in ICD-10 chapters IV, X and XX that are not connected with infection.

Register of venereal diseases (RPN)

Information systems of Institutions Protecting Public Health

PURPOSE OF DETECTION OF REQUESTED DATA

The purpose of investigation is to obtain information on selected venereal diseases for assessment of the evolution of the epidemiological situation on the CR territory, for monitoring of the health status of the population and for management of provision of health care. The results are transmitted to World Health Organization and to OECD.

RPN is a continuous sequel of the longtime statistical monitoring in IHIS CR (since 1959). Since 2003, RPN is operated as a web application with central database. Regional public health stations insert data to the register by means of internet connection via secure https protocol. Access to the register and assignment of user roles is authorised by the administrator of the register.

The internet component of RPN is founded by Ministry of Health of the Czech Republic and constitutes a component of the Information System of Public Health Service. Public Health Service is responsible for protection of public health and contributes to execution of Act no. 258/2000 Coll. on protection of public health and of Regulation of Ministry of Health no. 195/2005 Coll. on prevention of origin and apread of infectious diseases and on hygienic demands on operation of health establishments and institutions for social care.

STATISTICAL UNIT OF INVESTIGATION

Statistical units are all reported cases of venereal disease subject to notification, including relapses. The register includes all epidemiological notifications of venereal disease, on deaths with venereal disease, on suspected venereal disease and on identified sources of infection of venereal disease including cases detected in foreigners.

The following venereal disease are subject to mandatory notification:

Congenital syphilis (A50), early syphilis (A51), late syphilis (A52), other and unspecified syphilis (A53), gonococcal infection (A54), Chlamydial lymphogranuloma venereum (A55), chancroid-ulcus molle (A57).

Register of tuberculosis (RTBC)

Information systems of Institutions Protecting Public Health

PURPOSE OF DETECTION OF REQUESTED DATA

The purpose of investigation is to secure surveillance of TB in the CR and preparation of programmes of control of TB incidence.

The register monitors all persons in whom active tuberculosis or other mycobacteriosis was detected on the CR territory and persons followed-up in groups of active or inactive tuberculosis or other mycobacteriosis.

In the Czech Republic, since the 1950s all physicians are obliged to report as infected all persons in whom a new case or relapse of any form of tuberculosis is diagnosed. Data on all notified TB cases are monitored in the central register. The TB Register replaces local processing of parts dealing with aggregation of data from statistical forms and thus helps in creation and maintenance of high quality topical database protected against misusing of personal data, in the field of TB incidence in the framework of the CR.

 Since 2003, RTBC is a component of the information system of organs of public health protection and operated as a web application with central database. Regional public health stations insert data to the register by means of internet connection via secure https protocol. Access to the register and assignment of user roles is authorised by the administrator of the register.

An inseparable component of RTBC is now the database if the Information system of bacillary tuberculosis (ISBT). ISBT is a system of notification of positive results of mycobacteriological examinations. Every laboratory performing detection of TB is obliged to report positive findings. Connectivity of RTBC and ISBT contributes to control of completeness and validity of data on TB. At present the ISBT is operated by the National TB Surveillance Unit in the Faculty Hospital Na Bulovce.

Register of TB secures:

  • regular monthly collection of data on notified TB patients after validation by regional consultants of Surveillance over TB
  • semi-annual output files reports on epidemiological situation of TB and on TB control measures that are analysed by the National TB Surveillance Unit
  • if necessary and on request, processing of additional reports for analysis of epidemiological situation.

STATISTICAL UNIT OF INVESTIGATION

A statistical unit is every detected case of active tuberculosis or other mycobacteriosis and every microbiologically positive laboratory finding.
