Unsuccessful proficiency testing performance is unsatisfactory performance for the category or test/analyte in two consecutive or two out of three consecutive testing events, including events that are failed for non-technical reasons such as a late submission or failure to participate.
CLEP notifies laboratories following unsuccessful performance via a Laboratory Evaluation Report (LER) similar to the report issued after the onsite survey process. There are two types of LERs that can be issued: a 2-week notification or a cease testing notification. The decision as to whether the laboratory receives a 2-week notification or a cease testing notification is based on past performance, immediate jeopardy to patient care, and root cause of the unsuccessful performance.
Formal notification of unsuccessful performance will be made via email from the PT Administration Group. The laboratory will receive an email which will indicate that a PT document is ready for review and include directions to access the document using eCLEP. Documentation of the laboratory’s investigation and the laboratory’s plan of corrective action must be submitted electronically via eCLEP within two weeks of notification of unsuccessful PT performance. CLEP may request additional information. Failure to submit an acceptable plan of correction or failure to implement the plan of correction can result in administrative action or may lead to delays in issuing the laboratory permit.
Please note, removal of the category or test/analyte from the laboratory’s test menu, in and of itself, is not acceptable remedial action. Remediation programs should be designed based on the nature of the unsatisfactory performances and the area of clinical laboratory medicine involved.
2-week notification
The laboratory must:
- investigate and document the problem(s) that contributed to the unsuccessful performance and implement corrective action,
- conduct a retrospective review of patient results to ascertain whether similar error(s) existed in reports of test findings and notify the ordering physician if necessary, and
- reply to the LER within 2 weeks.
The laboratory's remediation must be acceptable to CLEP. If effective corrective action is not implemented and documented to the satisfaction of the proficiency testing technical section, the laboratory will be required to cease testing clinical specimens.
Cease testing notification
The laboratory must:
- cease testing for the analyte(s) involved in the unsuccessful performance
- identify the permitted laboratory where patient specimens will be sent for such testing
- investigate and document the problem(s) that contributed to the unsuccessful performance and implement corrective action,
- conduct a retrospective review of patient results to ascertain whether similar error(s) existed in reports of test findings and notify the ordering physician if necessary, and
- reply to the LER within 2 weeks.
The laboratory's remediation must be acceptable to CLEP.
Laboratories issued a directive to cease testing clinical specimens due to unsuccessful PT performance will be reinstated after:
- documentation of corrective action has been determined to be acceptable,
- the laboratory demonstrates satisfactory performance in two consecutive test events obtained from the same proficiency test provider (one may be an off-cycle event), and
- at least six months has elapsed since the cease testing order.
