Use of Proficiency Testing as a Tool to Improve Quality in Microbiology Laboratories

Abstract:
Proficiency testing (PT) is a valuable tool for assessing laboratory performance and verifying the accuracy and reliability of test results. Participation is required by the Clinical Laboratory Improvement Amendments (CLIA) of 1988 for each of the microbiology subspecialties (bacteriology, mycobacteriology, mycology, parasitology, and virology), and the regulations include specific PT requirements for each subspecialty. To determine the use and perceived value of PT beyond meeting CLIA requirements, the Centers for Disease Control and Prevention funded a cooperative agreement with the Association of Public Health Laboratories to convene a series of focus groups to query laboratory professionals responsible for PT. The seven focus groups were comprised of 60 laboratory professionals representing large and small clinical laboratories, microbiology subspecialties, and public health. While participants acknowledged the need to perform PT to meet regulatory requirements, many also cited benefits and challenges beyond regulatory compliance.
Insights
Proficiency testing (PT) is mandated by Clinical Laboratory Improvement Amendments (CLIA) regulations. Laboratory professionals recognize PT
Area of Science:
- Clinical laboratory science
- Microbiology
- Public health laboratory services
Background:
- Proficiency testing (PT) is essential for evaluating laboratory performance and ensuring test result accuracy.
- The Clinical Laboratory Improvement Amendments (CLIA) of 1988 mandates PT participation for all microbiology subspecialties.
- Specific PT requirements are detailed within CLIA regulations for each subspecialty.
Purpose of the Study:
- To explore the perceived value and utilization of PT beyond mandatory Clinical Laboratory Improvement Amendments (CLIA) compliance.
- To understand laboratory professionals' perspectives on the benefits and challenges associated with proficiency testing.
- To gather insights from diverse laboratory settings regarding proficiency testing practices.
Main Methods:
- Convening seven focus groups with 60 laboratory professionals.
- Participants represented various clinical and public health laboratories, including different microbiology subspecialties.
- Focus groups were funded by the Centers for Disease Control and Prevention through a cooperative agreement with the Association of Public Health Laboratories.
Main Results:
- Participants acknowledged PT's necessity for meeting regulatory requirements (CLIA).
- Many professionals identified benefits of PT that extend beyond regulatory compliance.
- Several challenges associated with implementing and managing PT were also reported by participants.
Conclusions:
- Proficiency testing offers value to laboratories beyond fulfilling regulatory obligations.
- Understanding these additional benefits and challenges can inform improvements in PT programs.
- Further investigation into optimizing PT for laboratory quality assurance is warranted.
