Coding COVID-19 - further clarification

Further clarification regarding COVID-19 encoding and registration in SIRI

At the end of May, the Public Health Agency of Sweden published a new document Fall definition when reporting according to the COVID-19 (folkhalsomyndigheten.se) Communicable Diseases Act with instructions on notification under the Communicable Diseases Act. After contact with the Public Health Agency of Sweden, we have been informed that they want the same definition of cases reported to SIRI.

I.e. confirmed cases based on at least one of the following criteria:

  • Detection of SARS-CoV-2 Nucleic Acid Detection
  • Insulation of SARS-CoV-2
  • Detection of antigen from SARS-CoV-2 and clinical picture compatible with COVID-19 and/or for household contact to confirmed case

Please note that results from self-tests i.e. where sampling and interpretation of test results are made by the person himself should not be reported. This is based on information from WHO COVID-19: Case Definitions (PowerPointPresentation, who.int)

After contact with the National Board of Health and Welfare's classification unit, we have been informed that it plans to adjust the text for the code U07.1 in accordance with the text from who.

We expect that in practice there are a very small number of patients added as most with positive antigen tests are confirmed with PCR.

U10.9

For U10.9 Multisystemic inflammatory syndrome associated with COVID-19, that code should be supplemented with U07.1 or U07.2 in cases where MIS-C occurs early in the course of the procedure, (in connection with ongoing infection).

All paediatric cases with suspected or confirmed COVID-associated hyperinflammation should be recorded in the Pediatric Rheumatoid Register. Check with the patient responsible doctor that this is done.
