The National Register of Cardiovascular Operations and Interventions (NRKOI) consists of two modules. It consists of the cardiosurgical operations module (NKR) and the cardiovascular interventions module (NRKI) .

The purpose and meaning of the register: The National Registry of Cardiovascular Operations and Interventions (NRKOI) is a nationwide population-based registry that collects data on performed cardiovascular interventions in people with ischemic heart disease and performed cardiac surgeries. This is a merged register, which was created by merging the long-running National Register of Cardiosurgical Operations and the National Register of Cardiovascular Interventions into one system.

This merger brought simplification of the administrative burden and at the same time made it possible to monitor the interconnectedness of the care provided to patients with heart disease in a common register and thus increased the value of all monitored data. These are clinically confirmed data on the patient's condition and all performed procedures, including a detailed description of the procedures, methods and materials used, which cannot be replaced by any other existing source of information.

Both registries complement each other and allow users of both specialties (cardiology and cardiosurgery) to obtain detailed information about the patient's disease history, risk factors, anamnesis, the method of treatment, procedures used, medical devices, and above all, the results of treatment. Together, it enables better coordination and continuity of care provided to patients with cardiac disease. In acute cases, they allow you to quickly find out information about the patient's previous treatment.

It can be said that the National Register of Cardiovascular Operations and Interventions is an important part of the comprehensive and standardized information support for increasing the quality and efficiency of cardiac surgery and cardiology care in the Czech Republic. Currently, its relatively extensive database is available to the professional public as well as competent institutions of the Czech healthcare system, led by the Ministry of Health of the Czech Republic, and enables:

• system for monitoring and evaluating the results of individual methods, procedures and workplaces,
• monitoring and evaluation of the causes, development and consequences of serious cardiovascular diseases and conditions,
• determination, monitoring and evaluation of national indicators of the quality of cardiac surgery and cardiology care,
• determination of qualitative accreditation indicators based on scientific foundations,
• provision of individual prognostic information for individual types of cardiosurgical operations and cardiovascular interventions, necessary for the clinical decision-making process of doctors,
• assessment of the needs and status of cardiac surgical interventions and cardiac surgical operations in terms of quality, effectiveness, results and expenses, 
• identification of inadequate, potentially inappropriate interventions and treatments that do not achieve expected results.
