Aim of database:
To systematically monitor and improve the quality of treatment and care of patients with schizophrenia in Denmark. In addition, the database is accessible as a resource for research.
Study population: Patients diagnosed with schizophrenia and receiving mental health care in psychiatric hospitals or outpatient clinics. During the first year after the diagnosis, patients are classified as incident patients, and after this period as prevalent patients.
Main variables: The registry currently contains 21 clinical quality measures in relation to the following domains: diagnostic evaluation, antipsychotic treatment including adverse reactions, cardiovascular risk factors including laboratory values, family intervention, psychoeducation, postdischarge mental health care, assessment of suicide risk in relation to discharge, and assessment of global functioning.
Descriptive data: The recorded data are available electronically for the reporting clinicians and responsible administrative personnel, and they are updated monthly. The registry publishes the national and regional results of all included quality measures in the annual audit reports. External researchers may obtain access to the data for use in specific research projects by applying to the steering committee.
Conclusion: The Danish Schizophrenia Registry represents a valuable source of informative data to monitor and improve the quality of care of patients with schizophrenia in Denmark. However, continuous resources and time devoted is necessary to maintain the integrity of the registry and the validity of the data.
