of Mobile Computing System in Clinical Environment: MobileNurse
|
Abstract
The purpose of this study was to develop MobileNurseTM; a prototype
of mobile nursing information system using PDA; it was used for
retrieving patients information such as, physicians orders
and test results at anywhere or anytime. We tested it in clinical
settings. It enable nurses to provide point-of care by reducing
time-consuming, redundant paperwork, therefore, ultimately, it will
improve the quality of care.
Introduction
In the past dozens of years, progress in the development of computer
technology has been remarkable. The features of this progress is
active, collaborative, intelligent, and mobile. Computer has played
an increasingly important role in diverse areas of industry.
Health Care is one of the last industry yet to undergo complete
computerization. Although we currently call up laboratory results,
order tests, and bill patients using computerized systems, many
facilities are still using age-old manual methods for recording
clinical information and physicals, nursing notes, assessment, and
treatment plans.
Furthermore, with the wealth of technical improvement in health
care, the need for information technology innovation is increasing,
not only in use of computer-based patient record, but also in enabling
infrastructures to support health information interchanges. There
are many new technologies which are being developed to improve the
efficiency and productivity of nursing staff. Nursing information
system is useful for decision support, point-of-care documentation,
interagency and interdisciplinary communication.
Timely access to data related to the patient at hand is critical,
especially, in health care environment requiring rapid clinical
decision making. In addition, patients seek information which are
about their conditions. Therefore, systems that enable nurses to
share information with patients at any time are also needed, regardless
of place.
The purpose of this study was to develop a prototype of mobile nursing
information system: it was used for retrieving medical orders and
test results and it will also be able to connect and interchange
with the hospital information system in terms of patients data.
This paper will presents the development of MobileNurseTM, mobile
computing system; clinical trial of MobileNurseTM; and future directions.
Development of MobileNurseTM
PDA is abbreviation of Personal Digital Assistant. It is capable
of handling several personal functions such as a memo, address,
schedule and also can interface with a personal computer. Its size
is small enough to handheld.
There are diverse kinds of models of PDAs and Cellvic is one of
them. It has been made by JTEL; which is the company that specializes
in mobile computing systems.
Our ultimate goal was to implement mobile computing system which
communicate with HIS; Hospital Information System, directly. We
have divided the framework of development into two stages; First,
to implement the interactive system between PDA and Mobile Support
System. MSS is a unit server located at the nursing station, it
stores and communicates patient data with PDA. Second, to interface
PDA with HIS. We assumed that MSS was interchanging with HIS and
focused on sharing and interchanging of patient data between MSS
and PDA. In this study, we performed the first phase experiment.
Figure 1 represents the mobile computing environment and the picture
which is in a dotted line indicates our research framework.
PDA communicates with HIS via MSS. We developed autosynchronization
module to interchange updated information between PDA and MSS consistently.
If you placed PDA on the cradle which is connected MSS, autosynchronization
is executed.
Our subjects were followings:
-
Collection and analysis of user requirement
-
Design of database of both PDA and MSS
-
Development of application program
-
Clinical trial of the system
Graphical presentation of developmental process of MobileNurseTM
is shown in Figure 2.
MobileNurseTM consists of four modules(Figure 3); Patient Information
Management, Medical Order Check, Nursing Recording, and Nursing
Unit Care Plan. Each module has submenus. Patient Information Management
module shows the patients list and displays individual demographic
information of patients. Medical Order Check module is help nurse
to check physicians orders. Nursing Recording module consists
of nursing notes, vital sign recording, checking fluid intake/output
of patient, pain assessment, and results of special nursing treatment.
Nursing Unit Care Plan module consists of submodules such as discharge,
clinical test, consultation, blood transfusion, operation, transfer,
and diet.
MobileNurseTM user interface is shown in Figure 4.
MobileNurseTM provides nurses with useful functions, for example,
like as followings:
-
Automatizing vital signs graph(Figure 5)
-
Calculating total amount of fluid intake/output
-
Pain Assessment Tool
-
Online retrieval of physiciansorders and test results
-
Nursing records at bedside
MobileNurse in Clinical Trial
We tested MobileNurse at the Clinical Trial Center, Seoul National
University Hospital, Korea. Six registered nurses volunteered and
performed nursing care for four stimulating patients with MobileNurseTM..
We used a pentium PC as mobile supporting system which supported
and communicated data with PDA. During the clinical trial, physicians
order was entered into MSS by doctors and the information was interchanged
between MSS and PDA when the autosynchronization was activated.
Nurses were able to refer patient data with PDA at any time or any
place, if necessarily.
We have surveyed nurses opinions about the MobileNurseTM
with a semi-structured questionnaire. It consisted of 4 parts; questions
about individual experience in computer, questions focusing on user
convenience, questions about MobileNurseTM, open questions
All six nurses have replied that it was helpful to check physicians
order and laboratory results at bedside. However, they indicated
that PDA was inconvenient for user to see a full view of patients
data because its screen was small rather than PCs.
Nurses opinions after clinical trial are summarized as following:
Positive response:
Negative response:
Discussion and Future Direction
A recent survey of health care organizations found that almost 30%
have automated the documentation process with computer-based patient
records. This trend is expected to continue, because the minimum
time for gathering and entering computerized documentation is less
than the minimum time for handwritten documentation. Considering
that nurses spend up to 50% of their time documentation patient
information, the computerization of these tasks is essential.
There are some reports similar to this paper. The research by Mcbride
et al. demonstrated the comparability of the paper and pencil methodology
in obtaining survey information in an ambulatory clinic. As a result,
the handheld computer method produced comparable scores to paper
and pencil surveys.
Wayne Memorial Hospital introduced a handheld point-of-care computer
for use on three madical-sugical inpatient units. System documentation
includes admission data, shift assessment, nurses notes, plans of
care, nursing interventions, and discharge summaries. Nurses surveyed
indicated that they spent less time charting and worked fewer overtime
hours after implementation of a system. It also permitted physicians
to view patient data any time from their offices with computer links
to the network.
We convince that MobileNurseTM reduce time-consuming, redundant
paperwork, consequently it enable nurses to be more time with patients
and to provide hand on care. In clinical trial, we found
that this system is useful for not only clinical environment, but
also diverse setting and health care environment such as community
nursing.
The future development issues in MobileNurseTM is in the following:
In addition, a PDA is useful for Evidence-based Medicine; The fundamental
concept underlying Evidence-based Medicine is that medical decision
must ultimately have a rational basis, and must rest on the results
of objective, rigorously conducted scientific experiment.
With use of PDA in clinical environment, nurses can be more time
with patients and provide hand on care right by reducing
time-consuming, redundant paperwork, therefore, ultimately, it will
improve the quality of care.
