Request from NCDC's Data Transition team

[Iheanacho2027]

Feature Description

The NCDC's Data transition team has requested for some specific changes on the module for measles, Rubella and yellow fever 1) Inclusion of a case classifications called "Discarded", "clinically compatible" and "Epidemiologically-linked" on the measles module 2) A test result called "Not Done" should be included to the measles and Yellow fever module @bernardsilenou @Chinedar @foyiri

@Iheanacho2027 This is a big change. The classification is linked to automatic case classification and all other logic in the system. A change to this would apply to all other diseases in the system. Can you provide a case definition + ref documentations of each of the categories: "Discarded", "clinically compatible" and "Epidemiologically-linked". This need to be programmed in the automatic case classification the is in the system

Is "Discarded" a case classification?

Good morning @bernardsilenou,

Below are listed guidelines that can help in the automatic case classification.

1. For IGM+, it was agreed that if a sample is tested in the laboratory whether it has an adequate volume of 5ml or not, as long as it is confirmed positive and has passed the lab quality check for that day, it should be considered a CONFIRMED CASE.

2. Similarly, for IGM-, if a sample is tested in the laboratory whether it has an adequate volume of 5ml or not, as long as it is confirmed negative and has passed the lab quality check for that day, is considered negative and will be DISCARDED.

3. If the sample is inadequate and cannot be tested, this should be considered as CLINICALLY COMPATIBLE

4. For samples awaiting laboratory testing, this would be considered as PENDING

5. For line listed cases that have clinical symptoms in keeping with a suspected case of measles, this will be considered as CLINICALLY COMPATIBLE cases. (A need to update the CIFs to reflect clinical symptoms).

6. In situations where an LGA is in an outbreak, any line listed cases with clinical symptoms in keeping with a suspected case of measles are considered epidemiologically linked.

7. We should ensure that epidemiologically linked are classified in the context of an outbreak in the LGA within the stipulated time period of an active outbreak in the LGA

8. For suspected cases with no sample taken, this should be considered as clinically compatible

I'm available for any clarity.

@generalkolo Thank for this information. Few comments:

• The definition you mentioned contain categories for "case classification" of a case and "test result" of a sample of the case. It would be good that we separate them.
• The case classification that are not implemented are: clinically compatible and epidemiological linked. Discarded == "not a case" in the app.
• The decision that was made in accordance with NCDC was to use the three broader and universal case classification categories: suspected, probable, confirmed + documenting all the information (clinical compatible, epi link,) that users can latter used to further classify the cases as they wish.
• I also think this change would apply to the whole system and not for measles alone.
• Lets schedule a call next week with the to discuss this further.

@bernardsilenou Comments well received.

• The definition of the "test result" was made to backup the second point made by @Iheanacho2027 when this ticket was created

"A test result called "Not Done" should be included in the measles and Yellow fever module".

• I'll speak to the Data transition team as regards using the "NOT A CASE" case classification for "DISCARDED".
• As regards the call can we have it tomorrow? The data transitioning is supposed to start on the 1st of Febuary 2021 hence the urgency.
