Microbiology subsystem of a total, dedicated laboratory computer system

Area of Science:

• Medical Informatics
• Clinical Laboratory Science

Background:

• The Microbiology Service utilized a dedicated on-line laboratory computer system.
• This system was integrated with the hospital's main computer for patient data.
• Existing laboratory workflows required optimization for efficiency and data accuracy.

Purpose of the Study:

• To describe the implementation and operation of a computer system in a clinical microbiology laboratory.
• To evaluate the integration of a laboratory subsystem with a hospital-wide computer network.
• To review the practical aspects, including costs and benefits, of introducing computerization in a laboratory setting.

Main Methods:

• Implementation of a microbiology subsystem within a departmental on-line laboratory computer system.
• Integration with a hospital computer for patient demographic data (admission, transfer, discharge).
• Utilization of mark sense worksheets and cathode ray tube terminals for data entry and correction; data archiving on magnetic tape.

Main Results:

• Enabled on-line access to patient data and efficient result entry/correction.
• Facilitated easy retrieval of results for active and completed accessions via terminals.
• Generated a research database and microfiched records from archived data.

Conclusions:

• The implemented computer system enhanced routine operations in the microbiology laboratory.
• The study highlights the importance of system integration, data management, and potential future enhancements.
• Consideration of costs, benefits, liabilities, and pitfalls is crucial for successful laboratory computerization.
