The survey process and guide for the medical laboratory are structured around the Laboratory Tracer activity, which evaluates how laboratory services are provided and integrated into the hospital's overall quality and safety programs.
Purpose of the Laboratory Tracer The tracer visit to the laboratory aims to address several key areas:
Section-specific policies and technical procedures.
Documentation of preventive maintenance and quality control.
Infection prevention, control, and safety practices.
Practices for specimen collection and processing.
Review and evaluation of the point-of-care testing (POCT) program.
Adequacy of staff numbers and their overall competence.
Review of blood bank practices, if applicable.
What Will Occur During the Survey The tracer takes place in the laboratory department as well as any areas outside the department where laboratory tests or point-of-care testing occur. Participants usually include the laboratory director, the laboratory safety officer, the individual overseeing POCT, technicians, and other staff providing laboratory services.
During the visit, surveyors will:
Assess the implementation of all elements of the laboratory safety program.
Review the hospital’s list of critical results, the process for managing them, the turnaround time (TAT) for critical results, and the TAT monitoring process for emergent/stat tests.
Discuss the POCT program, focusing on its scope, oversight management, performance data collection, and improvements made based on that data.
Review documentation for equipment inspection, testing, and maintenance.
Sample Survey Questions (How to Prepare) To prepare for the tracer, hospital staff should be ready to answer the following sample questions used by surveyors to assess compliance with specific standards:
