Case Classification Change for GERMAN COVID-19

[markusmann-vg]

Feature Description

Use the abbreviations listed below. The terms "unclassified", "suspected case", "suspected case", "confirmed case" and "no case" are then removed from the German SORMAS.

a. „nicht klassifiziert“ [A. nicht klassif.] b. „klinisch diagnostizierte Erkrankung“ [B. klin-diagnost.] c. „klinisch-epidemiologisch bestätigte Erkrankung“ [C. klin-epidem. bestät.] d. „klinisch-labordiagnostisch bestätigte Erkrankung“ [D. klin-labor. bestät.] e. „labordiagnostisch nachgewiesene Infektion, klinisches Bild nicht erfüllt“ [E. labor. o. klin Bild] f. „labordiagnostisch nachgewiesene Infektion, klinisches Bild unbekannt“ [F. klin-labor. unbek. klin. Bild.] g. „kein Fall“ [G. kein Fall] Die Buchstaben Kategorien sind sehr wichtig , das kennen die GÄ

--- english: a. "not classified" [A. not classified] b. "clinically diagnosed disease" [B. klin-diagnost.] c. "clinically-epidemiologically confirmed disease" [C. clin-epidem. confirms.] d. "clinically-laboratory-diagnosed condition." e. "laboratory-confirmed infection, clinical picture not fulfilled" [E. labor. o. clin picture] f. "Laboratory confirmed infection, clinical picture unknown" [F. klin-laboratory. unknown. clinical picture] g. "no case" [G. no case] The letter categories are very important, as the health departments do know and work with them

2. No logic besides: the demand of the system for positive corona laboratory test, whether it is a category d-f case

For the case statistics, the reference definition must be adopted - the RKI is using for the daily publications. The RKI management report writes: "Only cases are published where a laboratory diagnostic confirmation is available independent of the clinical picture", i.e.: D+E+F everything else must be excluded from the case statistics count, but included in the network representation. VERY IMPORTANT!!!

Additional Information

Proposal: Add two new fields for clinical and epidemiological confirmation above the case classification. The clinical confirmation will be read-only, once we have implemented the automatic logic for it. We could probably automatically update the SORMAS case classification based on this.

TODO: Find out, how this can be done for other diseases and what problems we may run into.

Ideas based on discussion with HZI:

• add a third read-only field that shows the calculated lab status
• maybe hide the case classification for German systems. THis would make it difficult for users to understand the dashboard, so we should probably better keep it and define and explain the mapping (e.g. suspect == clinically confirmed?)

HZI will check how suspect and probable actually map to the German definitions.

Migration:

Nicht klassifiziert => A Verdachtsfall => A Wahrscheinlicher Fall => B Bestätigter Fall => E Kein Fall => G

updates from German side: Use the following classifications:

    ◦ „nicht klassifiziert“ [0. nicht klassif.]
    ◦ „klinisch diagnostizierte Erkrankung“ [A. klin-diagnost.]
    ◦ „klinisch-epidemiologisch bestätigte Erkrankung“ [B. klin-epidem. bestät.]
    ◦ „klinisch-labordiagnostisch bestätigte Erkrankung“ [C. klin-labor. bestät.]
    ◦ „labordiagnostisch nachgewiesene Infektion, klinisches Bild nicht erfüllt“ [D. labor. o. klin Bild]
    ◦ „labordiagnostisch nachgewiesene Infektion, klinisches Bild unbekannt“ [E. klin-labor. unbek. klin. Bild.]
    ◦ „kein Fall“ [X. kein Fall]

Display as shown in the image, but add a field in which laboratory confirmed is also shown.

Hide the formulation “probable”, “suspected” and confirmed” in case file.

On the dashboard and transmission chain: • Do not show “probable” and “suspected” cases. Only show here laboratory confirmed cases (C-E) summarized in one number.

Handling of data which are already in the system: • Cases which are already “confirmed cases”  E. klin-labor. unbek. klin. Bild. • “probable” and “suspected” cases  need to be clarified
