Implementing complex networking laboratory information systems in a health maintenance organization.

Area of Science:

• Healthcare Informatics
• Laboratory Management Systems
• Health Information Technology

Background:

• Kaiser Permanente, Northern California Region (KPNCR) historically relied on manual laboratory information processing.
• Early automation efforts included card punch systems and mini-mainframe installations.
• A significant upgrade was needed to unify laboratory data across multiple facilities.

Purpose of the Study:

• To detail the implementation of a region-wide Integrated Laboratory Information System (LIS) at KPNCR.
• To document the transition from previous data management methods to a centralized LIS.
• To outline the timeline and scope of the LIS implementation project.

Main Methods:

• Implementation of a Cerner Corporation LIS software on a DEC VAX hardware platform.
• Phased rollout across 46 laboratories, starting with a pilot in August 1992.
• Database development commenced in September 1991, with full regional implementation by February 1995.

Main Results:

• Successful region-wide integration of laboratory information systems across 46 facilities.
• Completion of the LIS implementation within a 27-month timeframe.
• Establishment of a flexible, supportable, and robust laboratory information infrastructure.

Conclusions:

• The implementation of an Integrated Laboratory Information System significantly modernized KPNCR's laboratory data management.
• The project demonstrated the feasibility of large-scale health information technology deployment in a regional healthcare system.
• The chosen system provided enhanced flexibility and supportability for laboratory operations.
