5.3. Limitation
Despite of the benefits of the CPOE system, the study has some
limitations. We can cite:
- The feasibility study was not conducted on the field to get
real input on a district hospital using data collection technique like a
structured-interview. We have based our system and user requirement on existing
literature.
- Due to the time constraint the implementation of the system
on the field could not be conducted as well as the system assessment to get
users feedback
- The system used synchronous mode to send notification of SMS
and e-mail, that can create a delay with a relative long time of waiting when
sending the notification if the GSM network and the internet connection are not
good.
- To view the patient treatment guide line, the nurse has to
access the computer. Knowing that they are moving within the ward to provide
treatment to patient, this module should be deployed on mobile device such as
mobile phone or pocket PC and linked to the system through the wireless
intranet network.
5.4. Future works
Several work can be done in future to make the system more
efficient.
System interoperability
To allow the system to be very scalable and allow the exchange
of information with others system (OpenEMR, DHIS2), we have planned to use HL7
data exchange standard for communication between the client and the server
instead of simple SQL request based. With data exchange standard new module
(web or mobile) client can be added and deployed easily without the need to
reinstall or update the all client and server module.
New nurse interface module
The nurse has to be connected on the workstation to view
patient laboratory treatment guideline which is not a very friendly solution.
We have planned to develop a mobile application for cell phone or pocket PC
that will allow the nurses to access patient treatment guideline anywhere in
the hospital.
New specimen identification module
To allow an efficient identification of the specimen bring by
the patient, we have plan to update the specimen deposit feature in such a way
that a the patient ID and the associated bar code can be print and paste to the
specimen container to avoid physical error in patient identification.
