5 Need for Disruptive Innovation To Ensure Quality of HIV-Related POCT “ ---Many of the most powerful innovations that disrupted other industries did so by enabling a larger population of less-skilled people to do in a more convenient, less expensive setting things that historically could be performed only by expensive specialists in centralized, inconvenient locations---”

6 Elements of Disruptive Innovations: Cheaper, Simpler, More Convenient Products Or Services That Start By Meeting The Needs Of Less-demanding Customers----

7 New HIV-Related Point of Care Testing Guidance GUIDELINES for Assuring the Accuracy and Reliability of POINT of CARE TESTING National Policy Guidelines on Implementing Quality-Assured Point of Care Testing

8 Guidance for Assuring the Accuracy of Point of Care Testing Foundation for Increased Uptake, Coverage, and Impact of QA for POC Testing Policy Framework for Point of Care Testing

21 PMTCT Paediatrics STIs TB HTC Hepatitis Special Considerations Boxes Special Considerations for HIV Testing and Counseling AreaConsiderations for Programs POC tests currently used or in the pipeline for this program  HIV Rapid Diagnostic Tests (RDTs)  List of common RDTs currently approved and used by countries can be found via the following links: o WHO PQ List: RT_WHO-PQP_June2013.pdf o USAID Waiver List:  POC CD4 machines are also used to determine CD4 counts for HIV positive persons and facilitate linkage to care  In the pipeline device free POC CD4 tests, POC viral load testing Settings in which POC tests are used and operators in this program  POC tests are used in facility-based settings including ANC, TB, and STI clinics, outpatient departments and inpatient wards and co-located and stand-alone VCT sites. POC tests are also used in a wide range of community-based settings including mobile units, tents, workplace, homes, schools, etc.  POC HIV rapid tests are conducted by laboratorians, trained health care providers, and lay counselors. Several countries also have over the counter RDTs for the purpose of self-testing. Challenges associated with POCT in this program  Adequate training including refresher trainings for staff performing POC HIV rapid tests  Adequate mentoring for new staff and ongoing supervision for all staff to monitor and ensure quality of testing  Proper documentation incorporated into HTC or stand-alone registers for monitoring performance of tests kits and the individual performing them.  Focus on quantity (number of persons tested) instead of quality (did individual receive correct result).  Adequate QA procedures including proficiency testing to monitor skills of tester, retesting of positive patients to ensure correct test result prior to initiating treatment, post-marketing surveillance to identify problems with test kits, and follow-up at poor performing test sites with corrective actions to improve the quality of testing.  Flexible algorithms and functioning supply chain management systems to deal with and prevent stock outs of test kits and supplies  Providers adhering to SOPs, particularly in settings with limited human resources and high patient volume  National policies to support implementation of quality assurance efforts of POC HIV rapid tests.
