Ideally, a complete workflow would start with Step 1, Patient Identification, and proceed through to
Step 3, Results transmission. However, in resource-constrained settings the greatest value appears
to lie in Step 3, Results transmission. While Step 2, Orders, and Step 1, Patient identification,
remain important, in some cases these steps will likely remain paper processes. Therefore, these
profiles are described below in reverse order.
Use Case Title
Summary
Primary Actor
Secondary Actors
Results only
Laboratory expert wishes to run specific diagnostic tests and transmit results
to a clinician.
LIS
EMRs
Business Rules
Pre-condition(s)
Correct Patient Identification
Sequence of Events
Action/Stimulus
LIS receives diagnostic test results manually
through direct data entry or electronically from
analyzer.
System Response
LIS:
May store results in pre-existing records, or
Create new patient record(s) and store results
there.
The LIS transmits test results to EMRs/Clinician. The EMRs/Clinician acknowledges receipt of
updated records.
Post Condition(s)
Outstanding issues
Test result transmitted into correct patient record
and correct patient visit within that record.
Identity resolution in situations where there is
intermittent EMR-LIS connection.
