Microbiology subsystem of a total, dedicated laboratory computer system

Area of Science:

• Clinical Pathology
• Medical Informatics
• Laboratory Automation

Background:

• The Microbiology Service at the National Institutes of Health Clinical Center utilized a departmental 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 subsystem within a clinical microbiology laboratory.
• To evaluate the integration of this system with hospital-wide patient data.
• To review the associated costs, benefits, and challenges of laboratory computerization.

Main Methods:

• A dedicated on-line laboratory computer system was employed.
• Integration with the hospital computer provided patient demographic data.
• Mark sense worksheets and CRT terminals facilitated data entry and correction.
• Cumulative reports were generated, and data was archived on magnetic tape.

Main Results:

• The system enabled efficient data entry, result correction, and retrieval of active and completed accessions.
• Cumulative patient reports facilitated comprehensive record-keeping.
• Archived data supported the generation of research databases and microfiched records.

Conclusions:

• The integrated computer system significantly enhanced the routine operations of the microbiology laboratory.
• The system demonstrated benefits in data management and accessibility.
• Considerations for future enhancements and the evolution of microbiology systems were discussed.
