Manually triggered calculation of case classification [3]

[JaquM-HZI]

Further informations in #4770 (comment)

Situation Description

For Germany only, the case classification should be calculated according to the RKI standards, when clicking a button "calculate" which is next to the case classification

The calculation must be based on the information available in each case.
Belongs to #3004

Feature Description

Case category	Case definition	Description	Calculation basis
B.	Clinical-epidemiologically confirmed disease	Clinical picture of COVID-19, without laboratory diagnostic evidence but with epidemiological confirmation.	Clinical picture fulfilled but no positive sample (positive rapid antigen detection WITHOUT laboratory can be positive)
C.	Clinical-laboratory diagnostic confirmed disease	Clinical picture of COVID-19* and laboratory diagnostic evidence by nucleic acid detection or pathogen isolation (C1) or laboratory diagnostic evidence by antigen detection (C2)	Clinical picture fulfilled AND Positive PCR sample OR Positive antigen detectionfrom laboratory OR Positive pathogen isolation
D.	Laboratory-diagnostically proven infection if the clinical picture is not fulfilled	Laboratory diagnostic evidence by nucleic acid detection or pathogen isolation (D1) or laboratory diagnostic. Detection by antigen detection (D2) in the presence of a known clinical picture that does not meet the criteria for COVID-19	Clinical picture NOT fulfilled (all other symptoms without the ones for clinical picture) AND Positive PCR sample OR Positive antigen detection from laboratory OR Positive pathogen isolation
E.	Laboratory-diagnostically proven infection with unknown clinical picture	Laboratory diagnostic detection by means of nucleic acid detection or pathogen isolation (E1) or laboratory diagnostic detection by means of antigen detection (E2) in the absence of information on the clinical picture (not ascertainable or not collected).	Clinical picture unknown AND Positive PCR sample OR Positive antigen detectionfrom laboratory OR Positive pathogen isolation

*Clinical picture:
at least one of the following symptoms:

• Acute respiratory symptoms of any severity:
  - cough
  - pneumoniaClinicalOrRadiologic
  - acuteRespiratoryDistressSyndrom
  - respiratoryDiseaseVentilation
  - difficultyBreathing
• new-onset loss of smell or taste:
  • lossOfTaste
  • lossOfSmell
• disease-related death

Possible Alternatives

Additional Information

@kwa20

To do:
=> Remove validation
=> Add "calculate" option
=> In Germany automatic caseclassification = false

Development Specifications

• Extend the CaseClassificationFacadeEjb.buildCriteria method with ClassificationCriteriaDto for the two case classifications CONFIRMED_NO_SYMPTOMS and CONFIRMED_UNKNOWN_SYMPTOMS; only consider them for German servers
• Add a new extension of ClassificationCriteriaDto called ClassificationAllSymptomsCriteriaDto which is passed the SymptomsDto and a SymptomState and goes through all symptoms where the @Diseases annotation contains the disease in question and checks whether the value matches the given SymptomState; the eval method returns true if all symptoms match the SymptomState and false if at least one symptom does not match the SymptomState; should also be possible to call this criteria with null in which case it verifies that all symptoms have no value
• Extend the CaseClassificationFacadeEjb.buildCriteria method with code to build the classification criteria for CORONAVIRUS according to the following specifications; only do this for German servers
  • SUSPECT: at least one of the following symptoms: pneumoniaClinicalOrRadiologic, difficultyBreathing, cough, runnyNose, respiratoryDiseaseVentilation, acuteRespiratoryDistressSyndrome, lossOfTaste, lossOfSmell
  • PROBABLE: suspect + either epidemiological confirmation = YES (use ClassificationCaseCriteriaDto) or case is linked to an event with EventStatus CLUSTER (new ClassificationCriteriaDto needed for this)
  • CONFIRMED: suspect + a positive test result for CORONAVIRUS with the pathogen test types PCR_RT_PCR, ANTIGEN_DETECTION , ISOLATION or SEQUENZING
  • CONFIRMED_NO_SYMPTOMS: a positive test result (see above) and EITHER all symptoms that are enabled for Covid-19 set to false (use the new ClassificationAllSymptomsCriteriaDto) OR at least one of the following symptoms set to true: fever, generalSignsOfDisease, diarrhea, fastHeartRate, rapidBreathing, oxygenSaturationLower94, vomiting, chillsSweats
  • CONFIRMED_UNKNOWN_SYMPTOMS: a positive test result (see above) and all symptoms that are enabled for Covid-19 set to unknown or null (use the new ClassificationAllSymptomsCriteriaDto)
• Remove the (currently unused) logic that validates the case classification for Covid-19 cases on German systems
• Add a "Calculate" button next to the case classification that can be pressed to manually trigger a re-calculation of the case classification (same logic that is called when saving a case); this button should be visible irrespective of whether or not automatic case classification is turned on for the server; should only be visible if the user has the user right CASE_CLASSIFY

I linked the official RKI document there as well I think

• Add a checkbox to avoid sending this case to SurvNet - in GERMAN call this box please "Senden an Meldesoftware erfolgt in anderem Landkreis".
• Implement a logic that checking this box leads to a warning for the user that "this case actively is prevented from sending to SurvNet".
• Add a bulk action function to prevent the checked cases from sending to SurvNet (name this action "Senden an Meldesoftware erfolgt in anderem Landkreis")
• Add a filter for cases which are not supposed to be send to SurvNet (checked - see above) at the case directory
• Prevent also these cases that are part of an event cluster from sending to SurvNet when this mentioned box is checked

The comment from @maxiheyner is covered by a new issue #5324 and is NOT part of this one!

@JaquM Please add to the prio_list and priritize

[MateStrysewske]

@JaquM I've updated the development specifications based on the currently disabled case classification validation logic for German systems. I guess the clinical picture part is not up-to-date. Can you please update the clinical picture for Covid-19 based on the exact symptoms that we have in the system?

[StefanKock]

Found by @syntakker : Minor finding: Automated recalculation for case classification is not triggered when a cluster event is unlinked (for classification "suspect" + cluster event => "probable", unlink cluster event =>"suspect")

[sergiupacurariu]

When a cluster event is unlinked from a case, the case is not saved. The automatic calculation is triggered only if the case is saved. In case the event is unlinked the user could use the "Calculate case classification" button to manually trigger the calculation.

@sergiupacurariu we please need to add "sore throat / pharyngitis" as symptom for the clinical picture.
I'm sorry for this last minute change.

[sergiupacurariu]

@JaquM In the classification rules we have two sets of symptoms:

• first set: - Pneumonia (clinical or radiologic), Difficulty breathing/Dyspnea, Cough, Runny nose, Respiratory disease requiring ventilation, Acute respiratory distress syndrome, New loss of taste, New loss of smell. This set is used for: suspect, probable and confirmed
• second set: - Fever, Diarrhea, Fast heart rate (Tachycardia), Rapid breathing, Oxygen saturation < 94 %, Vomiting, Chills or sweats. This set is used for Confirmed classification - Unknown symptoms.
  Please let me know if this new symptom goes in both sets or only in one of them. Thank you!

[JaquM-HZI]

@sergiupacurariu the first set please
