Part I.
|
Getting started—the mission
|
Goals, objectives, and overview of uses in public health |
Define POCT as testing at or near the site of care and appreciate that the definition does not depend on the instrument format or size
Understand the fundamental goals and objectives of POCT for rapid and effective evidence-based decision making at points of need
|
Needs |
Introduce situations where POCT has proven benefits for public health
Describe the need for POCT in outbreaks, epidemics, and the current pandemic, as well as in disasters and complex public health crises
Understand the importance of generating fast results, so that triage can be performed efficiently and immediately
|
Companion Tests |
Why do POC monitoring of temperature, oxygen saturation, respiratory rate, and other key primary variables (e.g., d-Dimer) provide layers of protection, defense, and assessment along spatial care paths
|
Part II.
|
Fundamental principles and practice of POC testing
|
A. Technical
|
|
Needs assessment |
|
Instrument formats, selection, and validation |
Recognize basic formats for disposable, handheld, portable, and transportable POC technologies that perform in vitro testing
Describe disposable POC tests, including smartphone modules, and their advantages, disadvantages, and marginal cost-effectiveness
Have the ability to select and validate the correct instruments
|
Non-invasive monitoring versus in vitro diagnostic testing |
Consider the operating principles of non-invasive devices, namely pulse oximetry for monitoring of oxygen saturation, and continuous hemoglobin monitoring
Compare in vivo, ex vivo, and in vitro approaches and advantages
|
Specimen processing |
Contrast whole-blood versus plasma analysis, also dry blots
Outline specimen processing and suitable sample types for testing in the field, primary care, and emergency room
Review special requirements associated with isolation laboratories
|
Quality assurance (QA), quality control (QC), and proficiency testing (PT) |
Identify “waived tests” under CLIA ’88 and compare other POC tests
Know the definition and importance of quality assurance, including internal quality control and external quality assessment
Learn the five basic elements of the individualized quality control plan (IQCP), including environmental stress; how to customize QA, QC, and PT; and the importance of continuous quality improvement
Recognize confounding factors in diagnostic testing
|
Environmental stresses |
Overview the effects of environmental stresses on POC instruments and reagents, and how to avoid adverse consequences
Study methods for modulating environmental conditions for POC reagent storage and transportation
|
Multiplex molecular diagnostics |
Gain a basic appreciation of multiplex assays used for the detection of viruses, bacteria, and fungi, that is, pathogen detection
List advantages, disadvantages, costs, and limitations
Show examples of current POC disposable tests and instruments commercially available
|
B. Design & build
|
|
Design criteria |
|
Commercialization |
Understand custom POC test clusters, basic manufacturing requirements, commercialization processes, and timelines
|
Regulatory oversight |
Review routine FDA 510(K) clearance and pre-market approval (PMA)
Outline the FDA system of classification of diagnostic tests (i.e., CLIA-waived, moderately complex, and complex) and the criteria for home testing.
Assess the ramifications for implementation, personnel, and use
|
FDA and WHO emergency use declarations |
Study the process, legal requirements, and terms of FDA emergency use authorizations (EUAs) and WHO emergency use assessment and listings (EUALs)
Locate EUA and EUAL listings and documentation of tests on the web
|
Accreditation options |
Understand the definition of accreditation and why an organization would engage in it
Discuss the main considerations and steps leading to accreditation
Consider inspections options for POCT [e.g., College of American Pathologists, Joint Commission, and CMS (for waived testing)]
|
Part III.
|
Practicum
|
Device hands-on experience |
Demonstrate CLIA ’88 waived and moderately complex POC tests
Learn how to perform common POC tests, how to operate mobile POC instruments, and security features (e.g., UN & PW)
Watch demonstration videos of transportable whole-blood analyzers and test clusters for critical care and support of patients in isolation
|
Results interpretation |
|
Performance evaluation |
Attend a workshop illustrating POC performance evaluation, such as regression analysis, Bland-Altman plots, and locally-smoothed (LS) median absolute difference (“LS-MAD”) curves and maximum absolute difference (“LS-MaxAD”) curves
|
Trouble shooting |
|
Establishing a POC program |
|
