5.4.2. Improvements
identification
Based on the proposed framework for the district hospital
illustrate in the Figure1.1 (Chapter 1), we have identified five business
processes to automate for the improvement of the laboratory test order
management:
1. Patient administration management: provides patient
demographics information to the system. This process involves the management of
patient identification information such as names, record number, ID number and
patient location. The patient is uniquely identified with the medical record
number.
2. Staff administration management: provides basics
information on the profile of the medical staffs in terms of their working
categories or the duties they are supposed to perform to provide care to the
patient. The medical staff are identified by their professional identification
number such as license number.
3. Place order management: provides information on the
laboratory order requested by clinician for patients. Each order created by the
clinician should be identified with an Order Number.
4. Test result management: provides information on the
specimen collection for an order, their identification and management. Result
entry is also included in this process.
5. Order result management: provides information on the
follow-up and the tracking of the order result.
5.4.3. Requirements
definition
A requirement is simply a statement of what the system must
perform or what characteristics it should have. During a systems development
project, requirements are created to describe the business needs (business
requirements), what the software should do (functional requirements), the
characteristics that the system should have (nonfunctional requirements).
Business requirements
The business requirements are the statements that describe the
reasons for proposing the system development project. This section refer to the
justification of the study.
Functional
requirements
A functional requirement relates directly to a process that
the system has to perform to support the user tasks. The International
Institute of Business Analysis (IIBA) defines functional requirements as
«the product capabilities, or things that a product must do for its
users». By the analysis of main user tasks that should be performed from
the five business processes to be automated, the functional requirements listed
below have been identified.
§ Patient administration management:
The system will allow the clerk:
- To record new patients
- To subscribe the patient to receive notification of
laboratory result by SMS and/or e-mail
- To search a patient using his/her identification
information
- To update demographic information of the patient
- To view the list of the patient of the hospital
§ Staff administration management:
The system will allow the clerk:
- To record new medical staff
- To update identification information of the medical staff
- To view the list of the staff of the hospital
§ Place order management
The system will allow
- The clinician to request laboratories test for the
patient
- The clinician to choose to receive the lab result by SMS
and/or email
- The clinician to view the ordered laboratory group test for
a patient;
- The nurse to refer a patient to a clinician
- The nurse to view laboratory test request by the clinician
for a patient.
§ Test result management
The system will:
- Allow the laboratory technician to record the reception of
specimen;
- Allow the laboratory technician to identify the referring
clinician and patients;
- Allow the laboratory technician to record result of lab
test
- Allow the laboratory technician to record new external
laboratory order
- Send automatic SMS and/or email notification to both patient
and referring clinicianwhen the result are validated.
§ Order result management
The system will allow:
- The referring clinician to view the result of the lab tests
ordered
- The referring clinician to view laboratory test that have
been performed or not
- The referring clinician to enter treatment guideline for a
patient after viewing the lab result
- Any clinician who is authorized to access the system to view
lab order requested by another clinician and to enter treatment guideline
- Any clinician who is authorized to access the system to view
on the work station the alert notification of new results available
- The nurse to view the treatment guideline and the laboratory
test request for an identified patient and referring physician.
