METHODOLOGY

The aim of the statistics for mental and behavioural disorders is to give information about the occurrence of mental and behavioural disorders among the persons in outpatient, day care and inpatient psychiatric treatment and according to that evaluate the prevalence of mental and behavioural disorders in the population.

The data on mental and behavioural disorders is collected using the annual report “Mental and Behavioural Disorders”. This report must be submitted by all psychiatric care service providers which hold a relevant activity licence and which employ psychiatrist(s). The service providers submit reports through web-based data submission environment A-veeb. The data collection is legally defined in accordance with the Health Care Services Organisation Act (HCSOA) and decree by the Minister of Social Affairs on the basis of the HCSOA.

The reports include cases diagnosed by psychiatrists. Therefore, they do not include data about the cases diagnosed by family doctors, etc. Information about mental and behavioural disorders diagnosed by psychiatrists is submitted in an aggregated form by disease groups and diagnosis according to ICD-10. The data related to inpatient care and day care is distinguished from the data related to outpatient care.

Mental and behavioural disorders statistics is published in absolute or relative numbers (rate per 100,000 inhabitants using annual average population).
