Reyes General Hospital implemented a new Laboratory Information System (LIS) called LabSys. The hospital wants all patient information and laboratory test orders from its Hospital Information System (HIS) to be accessible in LabSys. It also wants laboratory test orders in the HIS to be automatically sent to LIS and for test status updates and results to be viewable in the HIS. This will allow for more seamless sharing of patient and test information between the two systems to streamline workflows and improve clinical care.

2. CHOSEN SCENARIO
• SCENARIO 2
Reyes General Hospital
(RGH) implemented a
Laboratory Information
System (LIS) called LabSys.
The hospital wants to see
and send all patients to
LabSys. It also wants orders
of laboratory tests in HIS to
be sent automatically to the
LIS. The hospital also wants
to know the status and
results of the tests within the
HIS.

3. CHOSEN SCENARIO
• WHY?
I can completely relate with this scenario since the
hospital where I work has a system completely like
this. Also, it amazes me how such different systems
can work seamlessly (most of the times). Lastly, of
all the systems we have, LIS interests me most.

4. WHAT ORGANIZATIONS/ENTITIES
ARE INVOLVED IN THIS SCENARIO?
• REQUESTING UNITS (Nurses and Ward Clerks)
– Nursing Units
– Emergency Department
– Outpatient Department
• PERFORMING UNITS (Pathology)
• Chemistry
• Cellular
Immunology
• Hematology
• Histopathology
• Microbiology
• Microscopy
• Serology
• SYSTEM HANDLER
– IT Department

5. WHAT
APPLICATIONS
WITHIN THE DIFFERENT
ORGANIZATIONS NEED TO TALK TO EACH
OTHER?
• Hospital Information
System (HIS)
• Laboratory Information
System (LIS)
• Electronic Medical
Records (EMR)

6. PROJECT GOALS FOR MAKING THE
ORGANIZATIONS/APPLICATIONS TALK
• ADMINISTRATIVE
Faster workflow since “Performing
Unit” is automatically informed.
Knows what is the status of the
result.
Can utilize audit logs for any
issues encountered.

7. PROJECT GOALS FOR MAKING THE
ORGANIZATIONS/APPLICATIONS TALK
• CLINICAL
Prevent repetitive requests of
laboratory procedures.
Faster result transmission.
Lessen human error for procedures
with computation (Chemistry).
Provide “alert” status for any
abnormal requests.

8. DATA ELEMENTS
THAT SHOULD BE
TRANSFERRED
1. Patient Identification Number (PIN) – 1234567890
2. Patient Name – Juan Santos dela Cruz
3. Date of Birth – January 1, 1990
4. Requesting Unit – Oncology Unit
5. Performing Unit – Chemistry
6. Order Number – 001255660987
7. “Item Code” – 000012
8. Procedure Name – Complete Blood Count
9. Procedure Status – FOR ENCODING,
FOR VALIDATION, FINAL
10. Requesting Physician – Mike Muin, MD 

9. AT WHAT POINT (ACTIVITY OR EVENT) IN THE
PROCESS SHOULD THE TRANSFER OF
INFORMATION HAPPEN? – TRIGGER EVENTS
• HIS TO LIS
 IDEAL: Encoded item(s) has been
validated.
 REALITY: Upon validating the procedures,
there is a barcode printed. This barcode
will then be scanned. That would be the
trigger event.

10. AT WHAT
POINT IN THE
APPLICATION/SOFTWARE
PROCESS SHOULD THE TRANSFER OF
INFORMATION HAPPEN?
• LIS TO HIS
– A change in the ‘Procedure Status’ has been
noted, especially when the procedure has been
finalized.

11. THANK YOU! 
