GAA Program Area -Surveillance and Infrastructure Development • Expanding and strengthening HIV/STI/TB surveillance programs • Strengthening laboratory support for HIV/STD/TB/OI - Surveillance - Diagnosis - Screening for blood safety • Monitoring and evaluation • Strengthening information systems • Training
CDC-LIFE Planning and implementation process Technical Strategies Country Program Planning Visits Implementation
Situation analysis in GAP countries Downturn in local economies Management and resource constraints Increased disease burden Institutions diminishing ability to cope
Situation Report - laboratory • Loss of trained personnel • Training of lab staff inadequate • Lack of oversight • Training materials not updated • Intermittent supply of reagents • Congested and in some cases unsafe laboratory environment • Health reforms
Rationale for GAP support • Strong scientific basis for GAP programs • Biological markers a priority to monitor program successes or failures • Additional work load – GAP programs • Overwhelmed laboratory system (polyvalent lab techs) • Need to create safe work environment
Laboratory assessment • National lab assessment a prerequisite for support - lab organization - review recent assessment - current lab activities - communication - reagents, test kits and test algorithms - MoH input - Partners – local and international
GAP approach to lab support • Laboratory technical strategy based on best practices • Strong partnership with host nation and regional organizations • Prevention focus with rapid demonstration of success while building long term infrastructure • Rational use of limited USG resources
Focus of GAP lab support Balance between: • Supporting quality technical laboratory services at national level –HIV/STI/TB/OI • Supporting the creation/strengthening of PH laboratory systems to support quality testing
Laboratory technical support • Strengthen National Reference laboratories: - Quality Reference work – national level (hub for GAA program activities) - Set national standards, guidelines and protocols - Perform QA/QC and national oversight • Support District level laboratory capacity/capability • Advocate Rapid Testing: point-of-service for programs • Training
Support for HIV activities • Based on in-country capacity and coverage High priority - Rapid tests with appropriate algorithms - Dried blood spots for surveillance - EIA based serological assays Low priority - Incidence assays - Viral load assays - Monitoring CD4/CD8 cell counts
Support for TB activities • Smear microscopy at all levels - diagnosis and monitoring • National surveillance for drug resistance - conventional - molecular
Support for STI activities High priority • Evaluation of syndromic management • Basic serology RPR, FTA-ABS, TPHA • Basic microbiology – gram stain Low priority • Molecular methods for diagnosis • Surveillance for STI drug resistance
Priorities for Technical capacity building • Proper staff recruitment and retention • Appropriate training and backstopping • Appropriate technology transfer
Priorities for physical infrastructure development • Provision of appropriate equipment • Providing reliable reagent supplies • Safe and efficient physical space - water, electricity • Logistics and transportation

GAA Laboratory Support Structure • Technical laboratory support working groups • Surveillance • Rapid tests, VCT and MTCT • TB • STI • QA/QC • Informatics
Why a Quality Assurance Workshop? • Matrix of professionals • NCID, PHPPO, NCEH, APHL, WHO, GAP • Varied experience in resource limited countries • Countries looking for strong partnership in a crisis situation • A united US response • Clear unambiguous messages from partners • Results of tests could be life-altering
Quality Assurance workshop exit competency • Common understanding of laboratory QA systems • Clear guidelines on the utility of QA in LIFE countries • The added value QA systems bring to the fight against HIV/STI/TB/OI • A plan of action for implementation in GAP programs • - institutional and non-institutional • - priority VCT/MTCT/Surveillance
