The Development of Online Delta Check System using the Workstation
|

Abstract
|
|
|
Background:
The application of the delta check in test in general chemistry detects both random and clerical errors, thus enhancing the reliability of tests. However, since this approach adds the burden of confirming the test results to the laboratory it
has
the disadvantage of lengthening the turnaround time of tests. We speculated that an online delta check system is needed to reduce the turnaround time since many of those test results that are detected through delta check are false positive.
Methods:
We developed an online delta check system based on the client-server paradigm. We used NCR3600 as the server and IBM 486 PC compatibles as clients. The database system used is Oracle 7.1 and the development platform used in clients is
Powerbuilder
and Visual C++.
Results :
In the system we developed, delta screening is performed when test results are input to the computer. The decision over the delta screening is made by comparing it against patient's clinical information and cumulative results within the same
screen.
Conclusions:
The developed delta check method makes it possible to reduce the turnaround time previously spent on delta screening by eliminating (1) the batch processing of tests that is needed in previous approaches (2) separate query on cumulative results
and
patient's clinical information for delta screening purposes.
