Total Laboratory Automation for Microbiology Activities: An HTA Analysis in an Italian Laboratory Setting

Area of Science:

• Clinical Microbiology
• Health Technology Assessment
• Laboratory Automation

Background:

• Microbiology labs face challenges with increasing sample volumes and workforce limitations.
• Total Laboratory Automation (TLA) offers a solution for optimizing workflows, safety, and resource use.
• This study evaluates TLA's impact on urine and blood culture processing.

Purpose of the Study:

• To assess the efficiency and economic sustainability of TLA implementation in a microbiology lab.
• To evaluate healthcare professionals' perceptions of TLA.
• To analyze the impact of TLA on urine culture and positive blood culture workflows.

Main Methods:

• A Health Technology Assessment (HTA) approach was used with real-life data from a single Italian hospital.
• Key performance indicators were established via literature review and expert consensus.
• Data were collected pre- and post-TLA implementation, including economic analysis and a professional perception survey.

Main Results:

• TLA reduced sample processing times, including check-in (67%), inoculation (up to 100%), and plate reading (69%).
• Economic analysis showed a 67% cost reduction in personnel time for urine and blood cultures.
• Healthcare professionals reported improved safety, reduced workload, and positive perceptions of TLA's utility and results.

Conclusions:

• Total Laboratory Automation significantly enhances microbiology lab efficiency and organizational capacity.
• TLA allows for better allocation and utilization of human resources in diagnostic laboratories.
• The findings support TLA as a valuable tool for improving overall microbiology procedures.
