National Register of Hospitalised Patients (NRHOSP)

National Health Registers


The purpose of detection of requested data is obtaining sources of information on health status of the population. National register of hospitalised patients at the same time provides reference data for qualitative and quantitative evaluation of activity of individual establishments for institutional (bed) care and their departments.

Data from NRHOSP are an important tool for management of health services and determination of conceptions and realisation of health policy of the state necessary for determination of the optimum network of institutional heath care establishments. Resulting information from NRHOSP are provided to World Health Organization (WHO) and other international organisations according to contract obligations.


NRHOSP is a nationwide population register that builds on the information system Hospitalisation maintained in IHID CR since 1960. NRHOSP keeps evidence on persons that were hospitalised in bed departments and whose hospitalisation was terminated in the monitored period. Data collection from all bed departments of bed care establishments was performed for the first time in 1981 and then in 1986. Data are regularly processed every year since 1992. Since 1994 registration of basic hospitalisation diagnoses is performed according to the 10th revision of International classification of diseases (ICD-10) that replaced the previously used 9th revision. Up to 1997 data were collected from bed care establishments without establishments of central organs (sectors of transport, defence and justice) that until then did not provide data.

Classification of hospitalised patients IR-DRG

Classification of hospitalised patients IR-DRG was implemented in cooperation with MH with validity as of January 1, 2006 on the basis of communication of CZSO no. 427/2005 Coll. It enables us to classify patients in acute bed care by their clinical similarity and comparability of costs of their stay in the bed care establishment. For IR-DRG classification in 2011 (the update of IR-DRG was declared in Communication of CZSO no. 323/201 Coll. with effect as of January 1) the definition manual version 008.2011 was used, with the software for automated grouping of cases according to DRG, so-called grouper, version 008.2011, and binding methodology material and code lists for use in IR-DRG classification, version 008.2011. CZSO issues every year an updated Communication concerning IR-DRG. Reference is presented on web pages of Ministry of Health and further on web pages of National reference centre.


A statistical units subject to mandatory reporting is a terminated hospitalisation of patient (including foreigners) in one bed care department of a health establishment disregarding the kind of admission and termination (discharge, transfer, death). NRHOSP does not register day care (one day surgery) that belongs to out-patient care
