2. Background of the Study
• Developing countries have neither financial nor
knowledge resources.
• BeSer medical care is provided by private hospitals which
are expensive. They are equipped with proprietary
Electronic Health Records (EHRs) which is extremely costly.
• Emergency Medical Service (EMS) is provided by public
agency (government), but it is not meeLng the demands of
people. Therefore, private EMS is emerging in Indonesia
which uses currently paper based health records (word
document format).
3. ObjecLve and Scope of Study
• The objecLve of this study is to find out a most appropriate
soluLon for Electronic Health Record (EHR) to be uLlized for
private Emergency Medical Service (EMS) in Indonesia in
order to replace the current paper based health record.
• Therefore, I have chosen the use of free open source based
soware (FOSS) to develop web‐based soware applicaLon
EHR in order to replace the current paper‐based health
record and to solve the lack of financial resources issue of
developing countries.

5. Study Approach
• To look and study at the open standard for electronic health
record (e.g openEHR) and open‐source based development
soware (e.g. Java Development Tools) in order to develop
an EHR system to be used by private EMS in Indonesia.
• To evaluate the developed EHR system from the view point
of its applicability in developing countries in general.
6. Study Methodology
• To take the openEHR standard as a basis because:
– It is open.
– It is ISO standard (ISO 13606)
– It clearly separates medical experLse and soware
experLse. Therefore, the EHR system can be
developed by IT experts efficiently.
• To use the Java Development Tools as a set of
soware tools because:
– They are free open source soware
– They are developed by volunteer internaLonal “Java
Community”. Therefore, advices are freely given by
members of the community.

10. Result of the Study
EHR Applica2on on Mobile Environment
• The EHR applicaLon has been tested in a server‐mobile client environment using
both iPod‐Touch whereas the mobile client is connected to the network via Wi‐Fi
(Wireless Fidelity) Network and Blackberry via GSM‐GPRS Cellular Network.

Mobile EHR applica2on tested by EMS Doctor and Paramedic in Jakarta
• The final tesLng of this simulaLon was actually done directly
by the end‐users (i.e. an EMS doctor and emergency
paramedics in Jakarta, Indonesia).

12. Study EvaluaLon
Feedback of the end‐user point of view from EMS doctor and paramedics
• EHR applicaLon had been evaluated by both an EMS doctor (Dyah
GusLnar Savitri, my sister who is in charge of EMS doctors) and EMS
paramedic (Jim Crouch, paramedics team leader who is an experienced
and licensed medical emergency paramedics from Australian Red Cross).
• “The access Menu is prac/cal, relevant and frequently used informa/on by
doctors and paramedics on medical emergency and hospitals/clinics. This
informa/on that you provide are easy to update and to be reviewed. You
can update and retrieve your medical informa/on record any/me and
anywhere through your mobile handheld device. This data is helpful and
crucial for all doctors, nurses or hospitals taking care of you. And it could
even save your life during a medical emergency.”
13. Study EvaluaLon
• The importance of openEHR standardizaLon in EHR applicaLon was
proven.
– I could develop and test this EHR applicaLon in 8 months period.
• The advantage of Free Open‐Source Soware (in this case is Java)
was proven.
– My EHR applicaLon can be run on various compuLng environment
such as, PC, Ipod‐Touch and Blackberry mobile handsets.
– Free.
• The benefit of web‐based EHR applicaLon was proven.
– Sharing of health informaLon among different medical experts is
possible.
– More efficient work sharing can be accomplished compared with
paper‐based health records.
– CompaLbility issue across different plakorm of device interface can be
resolved due to the web‐based soware technology.
14. Conclusion
• The Free Open‐Source Soware based EHR
applicaLon can solve the lack of financial and
knowledge issue in developing countries in
general.
• Further future study is needed to develop the
XML database format for the health
informaLon as a standard format for
possibility to convert the data to other
different technologies.
