Re: [Dhis2-devs] Multi-select dropdown or multi-select checkbox in tracker capture forms

 

Hi,

As indicated day before yesterday, I had an IDSR training session with a
group of public health specialists yesterday, and I raised the issue under
discussion:

Firstly, there was broad consensus that nobody would be interested in using
e.g. symptoms data for daily/weekly analytics in the sense Jason/Knut are
referring to above (i.e. counting the number of headaches, or calculating
what proportion of malaria cases that have sweats at night). The PRIMARY
use of such symptoms data for disease surveillance will be to enable
disease specialists to investigate the case if the initial lab tests
requested by the notifying health practitioner is negative - meaning that
the initial diagnosis probably is wrong and the specialists need to consider
- what additional tests to do using specimens already sent to the lab
- what additional specimens to request from the treating facility, if any
- what advice to give the clinicians treating the patient while waiting for
a final diagnosis
- what other alerts should be sent out and/or outbreak mechanisms mobilised
related to the differential diagnoses being considered
So as a simple example: if an acute febrile illness patient is initially
diagnosed with malaria and the blood smear or DBS analysis is negative, the
set of symptoms will be used to e.g determine what other test to conduct
and other interventions.

Secondly, the specialists did point out that the symptoms data MIGHT be
relevant for certain types of longitudinal research, like when trying to
find out if the typical symptoms of a disease has changed over time
(possibly due to pathogen mutations or other factors). A typical scenario
would then be to take let us say 5 or 10 or 15 years of case notifications
for that disease and what symptoms have been reported for each. You would
not use standard program indicators for that, though - you would simply
dump out all relevant cases then parse the symptoms text field (using
Excel, STATA, R, or whatever) for symptoms trend analysis.

Thirdly, based on the above, I do agree with Jason that it would be best to
keep non-standard symptoms & other "syndrome"-type comments in a separate
text field so that you don't risk "contaminating" the MULTI_TEXT
attribute/element with random stuff.

I think Abyot's grasp of this is very good:

1.
Introduce valueType "MULTI_TEXT", which when used for both an
attribute/data element and it's specified option set will enable users to
select multiple text values which will be inserted into the attribute/DE as
sequential values separated by e.g. a semi-colon. If there is a need for
free text values, then follow usual procedure and include "Other (specify)"
- a program rule using a LIKE operator will show/hide the Specify field if
so required.

2.
If a "MULTI_TEXT" option set is specified to be a drop-down list, there are
of course multiple ways to enable multi-selections:  you can use tick-boxes
or highlighting values with a SAVE button (i.e. there won't be any
duplicated values) or you can use double-clicking with the value
immediately appearing in the text box followed by re-filtering of the list
to remove the value already selected. A text filter on top of the option
list would be appreciated. If the option set is large and e.g. tick-boxes
are used with a small "SAVE" button, it would be preferable to always show
what's already selected on top even when scrolling to the next page.  (OK -
you get my drift here: whatever multi-option selection method you prefer
from a design view, just make sure it's easy to find options in a long list
and make sure users cannot choose the same option value twice).

If a "MULTI_TEXT" option set is specified to be a radio-button list, it
should be straight-forward and users cannot choose anything more than once.
BUT a radio-button list is only relevant with a reasonably number of option
values.

3.
Which brings me to a related issue: the choice of using drop-down values or
radio-buttons are now set at the program definition level. Would it be
possible to leave that as a sort of "default" parameter but then override
it either in the attribute/DE or option set definitions?

4.
The public health specialists yesterday also requested that it should be
possible to filter the symptoms option set based on the diagnosis - or in
more generic terms they requested that only symptoms relevant for a
specific disease should be shown. While I strongly argued against that
concept when it comes to symptoms - it would for instance negate their wish
to use longitudinal disease/symptoms pairs to reveal changes in symptoms
for a disease, and it also reduces the usability of symptoms data to
investigate indeterminate syndromes - there are some scenarios where
clearly defined relations makes this type of pre-filtering useful.

Concrete example: SA IDSR will be tracking 48 notifiable diseases, but
those 48 conditions actually covers nearly 650 specific ICD-10 codes. Right
now we have the Diagnosis field with an optionSet of 48 values and the next
ICD-10 field with an optionSet of ~650 values. It would be highly
preferable to filter the drop-down of ICD-10 codes to only show those
relevant for the specific condition/diagnosis specified. In practical
terms, this would require either optionSet attributes (preferable) or at
least one additional "groupfilter" field in the optonValue table.

5.
Finally, I agree with Jason/Knut/Alex and then Abyot's more specific
version that a collection of YesOnly DEs could be packaged as a
multiSelectProgramStageDataElementGroup. I'm less sure if that is required
also for attributes - the current problem is that a number of things like
searches are only supported for attributes and not DEs, so users end up
using attributes for too many things. If the same functionality were added
for DEs, we would have a more robust and logical model.

Calle
