Estimates of wastage with conventional diagnostics are significant

Based on weighted average of data from 3 countries1, 46% of CD4 test results were NOT

received by the patient2

Based on an average of 3 countries from a 2009 UNICEF review of EID service delivery,

50% of positive EID test results are NOT received by the patient3

Wastage associated with CD4 and EID tops $60+ million per year and almost 6 million tests where patients do not receive the result3

Evaluation: Time From Diagnosis To CD4 Staging And ART Initiation shows similar results in Uganda

POC CD4 increases the number of people initiating ART by cutting LTFU and reducing time to initiation

Uganda1

• Time to ART initiation: Reduced from 59 to 11 days

• LTFU: 50% increase in retention from diagnosis to ART initiation

• ART Initiation: 85% increase in ART initiation

Page 8: Accelerating access to innovative point of care HIV diagnostics

• Creating and sustaining a healthy competitive market for POC diagnostics where– The most patients have access to diagnostics– There continues to be innovation for increased value– New products can easily enter the market

• Signaling commitment to the POC market through uptake• Growing the demand side of the market

• Accelerating normative guidance on the use of HIV POC diagnostics

• Supporting the entry and uptake of new, quality products

• Achieving substantial public health impact

CHAI, UNICEF, and UNITAID are together committed to:

In order to achieve the overarching goals, the project will roll out in two phases

Page 10: Accelerating access to innovative point of care HIV diagnostics

Funding needs for HIV is expected to grow significantlyFunding needs for HIV is expected to grow significantlyMany countries already adopting emerging products in treatment protocolsPhase 1 will occur before a product becomes available and Phase 2 once it reaches the market

10

Phase 1: Market Preparation• Engage with suppliers to

accelerate market entry and negotiate pricing

• Support regulatory approvals and policy adoption by facilitating evaluations

• Conduct operational research to support normative guidance on the impact, cost-effectiveness, and appropriate use of POC

• Support national planning processes for POC

Phase 1: Market Preparation• Engage with suppliers to

accelerate market entry and negotiate pricing

• Support regulatory approvals and policy adoption by facilitating evaluations

• Conduct operational research to support normative guidance on the impact, cost-effectiveness, and appropriate use of POC

• Support national planning processes for POC

Phase 2a: Commodity Donation • Donation (half of estimated need) and

consolidation of demand through a single procurement system

• Leveraging volumes to negotiate ceiling prices

Phase 2b: Catalytic Implementation• Product agnostic implementation

systems, planning and support for uptake (training, etc)

• Coordination and collaboration with other initiatives

• Responsibly transition procurement and operations support for lasting impact

Mentoring/supervision

In order for POC testing to be effective, new systems for implementation must be created. These can be product agnostic.

• Objective selection criteria

• Exclusion criteria to determine eligibility

• Volume discounts and leasing

• Service and maintenance

• Standardized sample collection

• Systems training on clinic workflow

• Participation in global EQA schemes

• Daily internal controls

• Timing of ART and OI treatment

• Patient movement through services

• Open data systems to manage devices

• Data transmitted remotely by modem

• Tracking volumes for forecasting

• Program mgmt with real time data

• Regular site level follow up

• Problem solving w/ real-time data

• Healthy, competitive market with multiple competing products in each product class (CD4, EID, VL)

• Improved patient outcomes from earlier ART/2L initiation and decreased LTFU

• Regulatory and policy approvals for a range of products in focus countries • Research to support appropriate deployment and implementation systems• Improved market intelligence and encouragement for new suppliers to

invest in POC according to approved norms• Coordinated response among governments and partners for sustainable

Limited access to HIV diagnostics has been highlighted as a priority in the Treatment 2.0 Framework

Five priority work areas have been highlighted in the Treatment 2.0 framework

The Treatment 2.0 Framework for Action: Catalysing the Next Phase of Treatment, Care and Support, http://data.unaids.org/pub/Outlook/2010/20100713_outlook_treatment2_0_en.pdf

Priority work area 2: Provide Access to Point-of-Care and Other Simplified Diagnostics and Monitoring Tools

Page 20: Accelerating access to innovative point of care HIV diagnostics

MSF UNITAID Project alignment

MSF aims to show if and how simplified testing can work in remote and resource-limited settings and to provide an evidence base for the range of products, or combination of products, to use in which contexts (e.g. lab vs clinic, urban vs rural)

Synergy:• Evidence on the efficiency and use of diagnostics – alignment on OR

questions• Access to CHAI/UNICEF procurement agreements • Sharing work on implementation systems• Using evidence to determine appropriate deployment and integration

with existing diagnostics

Reduce risk of not testing, not receiving result, not acting on result

• 3 or 6 month Viral load• Routine viral load• Before TDF switch• At delivery
