1. Introduction
In Ethiopia, a primary health care unit consist of Health centers and
Health posts (HPs).
In each health post, Health extension workers (HEWs) are assigned to
give health service to the community.
Responsible to execute different health packages including
Integrated Community Case Management (ICCM) program …
4. Introduction …
ICCM program is an integrated management of childhood and
newborn illness at the health post level.
The main objective of ICCM program is to reduce child mortality and
morbidity by giving better health service to children and newborns.
Focuses on addressing leading causes of child mortality: pneumonia,
diarrhea and malaria
And also other medical cases (malnutrition, immunization ....)
ICCM medical guideline is used for ICCM service provision

2. Statement of the problem
While giving ICCM service to children, HEWs are expected to always
use ICCM guideline. High adherence to usage of the manual guideline
is very much required.
Performing diagnosis and treatment without using the guideline has a
risk of committing clinical error
Medical procedures are not easy to remember (especially for less
experienced HEW)
But in the current practice, less adherence to guideline usage is
observed
6. Statement of. Cont.
Poor medical data reporting
and documentation were also
observed
Child’s medical case is
recorded in a paper-based
form
Incompleteness and
inconsistency in the medical
records were observed.
Giving continuous supportive
supervision to HEWs is also a
challenge
Supervisors can not reach all
HEWs regularly

Statement of. Cont.
In the current system, paper based clinical guideline is
used together with a registration book

3. Objective
General Objective:
It is to design and develop mobile based decision support system
to help HEW to give better service in ICCM program
Specific Objective:
Conduct requirement gathering (interview and field observation)
Model the ICCM guideline to electronic form with a selected
modeling tools/language
Design the proposed system based on the requirement
Develop a prototype and
Pilot test the prototype in the field

e-IMCI:
e-IMCI is a PDA based decision support system that guide
clinicians through a series of preprogrammed algorithms based
on IMCI protocol.
Help to achieve
High adherence to the protocol
Reduce skipped steps and branching errors
It is pilot tested in Tanzania
Electronic Decision Support in the treatment of AIDS
patients in South Africa:
It is to support screening of HIV+ patients to determine where
they can get treatment and follow-up
An electronic HIV treatment guideline is used
This system is pilot tested in South Africa

5. Proposed System
Mobile based DSS system
is proposed.
It has a client-server
architecture with decision
support, data collection
and data reporting
modules
The system has the
following hardware-
software mapping
Figure 2: Hardware-software deployment diagram for the proposed system

6. Implementation
The ICCM guideline is modeled with an open
source business process management suite called
jBPM.
The electronic ICCM guideline is stored as BPMN 2.0
specification.

For the client-side, Android based smart phone was
selected. Android is chosen because
It is based on an open-source platform and has better
localization capability,
Availability of tools like ODKCollect, a mobile based data
collection framework, and an Amharic virtual keyboard for
data entry.
For the server-side, Django web framework were
used to develop the web-based application.

Edit filled medical records
Send filled medical record to
server
Download new rule, forms, and
feedbacks given from server
Delete existing medical records

Assessment:
Questions for
assessing medical
case of the child is
displayed one by one.
Xform technology is
used to develop the
form

classifies the medical
case of the child based
on assessment made
and the electronic

Implementation Cont.
Server-side system:
Medical history of the child is compiled at the server side. For this purpose, ID is given to
each child to uniquely identify each child and it medical encounter

7. Next phase - in the target environment
Involving participating stakeholders to pilot test the
system in selected HPs
Training HEWs on how to work with the system, and
Run the system for specific period
Perform usability testing with HEWs
Evaluating the system and make adjustments based on
the experience gained
And proceed with system deployment to other HPs
19. 19
9. Conclusion
With the system proposed, it is expected to achieve
High adherence to usage of ICCM guideline
Better medical record reporting, storage and documentation
Better means to give supportive supervision to HEWs from
remote by sending feedback to HEWs
For the future, the system can be customized or
extended
to run on other mobile platforms;
to support other regional languages; and
to support other related health programs.
