Background
• Diverse user groups require data obtained
from queries of laboratory information
systems (LISs) for purposes including
research, operations management, and QA.
• Managing data searches is challenging when:
– search requests originate from diverse
locations in a health system
– laboratories at multiple locations are
supported by a single LIS
– personnel that perform searches are at
sites remote from the laboratory
Walter H. Henricks, M.D.
Objectives of Project
• Develop a Web-based system to improve the
request and delivery of LIS data searches
across multiple hospital laboratory locations
in a health care system running a centralized
LIS
• Build an effective communication process
around data search requests, beyond just
creation of an online request form

Technology - Laboratory Data Search
Request (DSR) system
• Web-based application (ASP.NET, Microsoft
Corp.), handles Web forms for submission,
assignment, and tracking requests
• Database management system (SQL Server,
Microsoft Corp.) manages all information
provided by the requestors and assigned
analysts

• Data Search Request (DSR) system access page
Walter H. Henricks, M.D.
• Web-based form for TPO (Treatment, Payment, Operations) request
• Users enter contact information and search criteria
Walter H. Henricks, M.D.
• Web form for non-TPO request (research) form
• Users enter contact information, search criteria,
HIPAA/IRB compliance
Walter H. Henricks, M.D.
• Upon submission, each request is assigned a unique number in
the database and routed to an analyst for the appropriate
information system (CP, AP).

• Web form for lead analysts/managers to assign search
requests to performing analysts
Walter H. Henricks, M.D.
• Assigned performing analyst gets a notification e-mail
Walter H. Henricks, M.D.
• The requestor receives a confirmatory e-mail including
contact information for the assigned analyst.

Final Step in Fulfilling Search
Requests with DSR
• Upon completion of the search, the analyst
marks the request as complete in the
database, and the requestor receives an
email with the search output data file.

Data Search Request System (DSR): Results
and Impact
• Complete, successful replacement of previous paperbased search request and fulfillment process.
• 400 requests processed since go-live (6 months).
• Confirmation to requestors that their request is in
process - NEW
• Elimination of delays due to incomplete request
information (required fields on form) – NEW
• Improved management and process metrics for
available from database – e.g. request volumes,
search types, requestor volumes, turnaround time NEW
Walter H. Henricks, M.D.
Conclusions
• Development of an on-line Laboratory Data
Search Request system facilitates fulfillment
of LIS data search requests in a
geographically and operationally distributed
environment.
• Linkage to a back-end database improves
management of the search fulfillment
process.
