Some more points on the design of community-based system.

One thing very important, the whole point is not to build a medical record
system but to build a feeder system to DHIS2 for specific programs like
Family planning, Immunization and ANC - for the context of house-to-house
service delivery and also at a facility. With a possibility for other
programs....

With DHIS2 acting as a baseline for subsequent analysis, presentation,
plotting, charting and graphing pulling the data into DHIS2 is very crucial
and for that we are going to rely on aggregation service - which is yet to
be implemented.

The way forward for the aggregation service, we planned, is to base on the
concept of Multidimensional DataElement and use options and their
combinations as drop-down choices for dataentry. For example we can have
weight of baby as a dataelement and make Under Weight (xxx g. - yyy g.),
Normal Weight (aaa g. - bbb g.) and Over Weight ( ccc g. - ddd g.) as
options and will be used in dropdown for dataentry. Latter we can count
Number of Babies Under Weight, Normal Weight and Over Weight and pass it to
DHIS2. We can also have a summary, for example the number of condoms
distributed during the month.

This will require us to classify our dataelements based on their type of
aggregation operator for example type SUM, type COUNT and type BOOL - which
we already have in the existing dataelement of DHIS2. But a limitation with
this approach no free text is allowed in the system - may be the team from
India can comment. I am only suggesting this approach from the experience of
the Indian Line Listing module. Actually would be great if we could get the
translated dataentry screens as soon as possible so that we make sure we are
in the right track.


Would be happy to get comments - especially on any complex mode of
aggregation - like other than counting summary and yes/no classification.


Thank you
