[Jason Pickering <jason.p.pickering@xxxxxxxxx>]

Hi there. I spoke with Knut briefly today regarding this long thread
and thought I would air some of my views about this. I think we are
getting there, and the diagrams will certainly help. I think the
description provided by Ola approaches a nice blueprint.
We had done some work on the development of a comprehensive public
health data model at WHO a few years back, and it may be worth getting
these diagrams out as well. This was based primarily on looking at the
OpenMRS, DHIS,  GlobalAtlas (WHO's primary data management
application), and the HealthMapper data base. We tried to bring
together these into a single data model, and I know we do have the UML
diagrams somplace. Perhaps Knut can help to dig this out. Knut?

I just want to be very sure that we are not trying to recreate a
patient-record system, and that seems to be the case. However, it is
going to be a fine line between not trying to create a OpenMRS-type of
medical record system and still capturing the most important
requirements for a CHIS.

 In terms of what is required here in Zambia in this regard, I must
admit that I cannot provide a complete picture. I discussed this with
a group of district health information officers last week, and from
their perspective, they needed a system to simply capture data from
community health workers. These workers are seen as an extension of a
particular facility here. They submit monthly aggregate totals to the
facility. The requirements were very basic and could be accomplished
simply by adding another organizational unit below the facility to
represent each CHW. There was really no immediate requirement to
extend some type of computerized system to the level of a CHW and will
not be for a long time here probably.

Obviously the requirements are different here, but I am feeling
somewhat uneasy about the push to start coding until the community has
agreed upon the basic requirements (well expressed by Ola) and arrived
at a comprehensive data model that would support future development
efforts, as well as basic ones.

Regards,
Jason
