Laboratory Test Support
Module (LTSM)
Message Terminated (MT). The MO is used for
sending SMS and MT is for receiving SMS. Once
an SMS is sent from a mobile phone, the message
arrives at Short Message Service Center (SMSC).
SMSC generally follows Store & Forward rule,
which means message is stored inside SMSC until
it reaches the recipient. SMS messages do not
have to be responded to. In addition, messages
can be linked to various other services and can
directly use their format. Both text and binary
data of limited length can be transmitted by SMS
and it can be automated (Mark Ridgeway, 2002)
such that it is sent at a particular time such as in
a medication alert system discussed in this paper
This support system aims at improving patient
safety and efficiency in care delivery. A doctor
may want to confirm the presence or absence of
diseases by requesting that a patient undergoes a
test. Laboratory test include blood, urine, sputum
etc. After the test is performed, the result is given
to the patient or captured and committed directly
to the system for later use by the referring physi-
cian. Where X-rays or other forms of scan are
required, the laboratory personnel and the X-ray
specialist perform the respective tests and save
the report separately on the server based system
with the patient's identity. Especially where the
client device does not have capabilities to store
image files.
Systems Architecture
The SMS integrates with core e-Health based
systems (Ikhu-Omoregbe et al., 2010). The e-
Health system consists of the following modules:
Pharmacy and Billing Support
Service Module (PBSSM)
Patient Medical Record
Support Module (PMRSM)
This module is a patient-centred, browser-based,
integrated management medication system, pro-
viding drug therapy, billing and documentation
for every step of medication treatment process.
Its functionality includes: checks for drugs in-
teractions, billing and allergic drug alert. The
module helps to minimize medication errors and
adverse drug effect on patients by allowing phy-
sicians send prescription information directly to
the pharmacist after reviewing patient's allergic
medication list real time via hand-held devices.
The module helps to eliminates transcription er-
rors and minimizes the time delays between the
patient's consultation session with the physician
and the collection and administration of drugs. By
making patient medication information available
electronically, accessible anytime, regardless of
the location within the care network, cost of treat-
ment is substantially reduced and lives are saved.
This is the core support service in e-Health based
systems. It provides functionality that maximizes
the usage of the patients' medical information
by serving as central sources of information for
communications between health care providers,
covering the patients' history, observations, and
diagnosis.
This support service is not limited to only
the interactions recorded in the patient-doctor
encounter database but draw from numerous
different facilities and support services such as
records from the database of laboratory test, medi-
cations, and appointments, and diagnosis. This
system allows an authorized user to view patient
medical records real-time, in other to undertake
treatment processes that are most beneficial and
cost effective to the patients.
