Computers and computer applications are the backbone of today’s healthcare. ]. C
o
A patient who does not feel right seeks medical help by asking the healthcare p
y
rig
provider to diagnose the problem and prescribe treatment that will return the h
t ©
patient to activities of daily living. The healthcare provider uses a computer M
c
G
application to review the patient’s medical history that includes recent visits, ra
w
diagnoses, medication, and treatments. -Hill G
If the patient needs to be admitted to the hospital, computer applications lo
b
a
are used to collect admitting information. The computerized physician l E
d
u
order entry (CPOE) system is used by practitioners to write medical orders. ca
tio
The order management system processes orders and displays results of orders n H
o
entered by practitioners and nurses. The electronic medication administra- ld
in
g
tion record (eMAR) system is used by nurses to identify medications to s, L
L
administer to the patient and record when the medications are given. The C. N
o
physician documentation system enables practitioners to electronically doc- t to
b
ument the practitioner’s interactions with the patient. The electronic med- e re
d
ical record (EMR) system is the patient’s chart that is used by the patient’s istrib
medical team to record electronically all information about the patient’s ute
d
stay. or m
o
All clinical computer applications are implemented by a team of clinical and d
ifie
management information systems (MIS) specialists typically led by a nurse who d in
a
specializes in nursing informatics. The nursing informatics specialists interact n
y
w
with the clinical staff and administrater to identify clinical needs and then fulfill ay
w
those needs working with MIS and third-party vendors. ith
