Product Selection Methodology

Country Case Studies

Site Selection

Implementation

Why is a product selection process necessary?

4

• Comprehensive product information – Historically, in the diagnostics sector, decision-makers have lacked sufficient

information to make fully informed product selection decisions - – Suppliers provide MOHs with extensive marketing materials, but they often lack

comprehensive and unbiased information to pick the products that are most appropriate for their countries

• Public procurement principles– Public funding requires that public procurement principles be observed in the

procurement of commodities. MOHs have an obligation to demonstrate that a rational and transparent process has been followed to select products for procurement.

There is a role to play for neutral 3rd parties to facilitate the development of a rational and transparent product selection process.

Key Principles of Product Selection:

5

1. MOH-led

2. Involvement all key stakeholders to drive consensus

3. Rational and transparent criteria

4. Good documentation of the process

5. Allow flexibility for each country to customize according to its needs

6. Be an iterative process

Facilitation of the product selection process has included both quantitative scoring and qualitative discussion among MOHs, TWGs, etc.

Determine key criteria

o Determine the most important ~5 – 10 criteria when selecting POC productso Discuss how these criteria should be weighted against each other in each segmento Determine if any of these is critical i.e. must be met (e.g. connectivity or electricity-free)

Review product pipeline and assign scores to products

o Review all available information for each producto Assign scores for each of the products for the criteria determined in step 2

Select POC products

o Review scores for each product in the various segmentso Hold discussions across all stakeholders to consider scores and other relevant factorso Select products for evaluation and/or scale-upo Repeat process periodically to include new products and new information

Understand current testing landscape

o Understand the current gaps in testing coverage in the country: What segments have the poorest access to testing? At what level of the health system do most patients seek care? Which segments of the health system would be best served by POC?

Select CD4 POC productso The tool provides scores for each product in each segmento The group discussed the resulting scores:

o Which products scored best in each segment?o Were the results expected? If not, what was missed?o What additional data is required to improve the accuracy of the scores?o Are the differences between various top scoring products significant?o How many products are needed in the country?

o The group, led by MOH, documented its selections with formal meeting minuteso The group made plans to repeat this process in the future

Hand in hand with product selection, appropriate deployment is critical to successful utilization of POC devices

Convene TWG

Conduct evaluations

Review product information

Convene TWG Review evaluation results

Pilot/Scale-up


There is a sweet spot for sites where laboratory based and POC testing make economic sense based on throughput, cost and complexity

Actual share of the market will depend on:1. Country preference

Leverage current laboratory based platforms?2. Price points for device/reagents

Cost of POC test vs laboratory based + sample transport3. Throughput of POC/near-POC

# of machines required to meet patient need vs. burden on health workers4. Guidelines on DBS

Without DBS, laboratory based may not be able to reach peripheral sites

Highest volume sites Lowest volume sites

Suited to laboratory based Suited to POC

Criteria Provincial Hospitals District Hospitals Health Centers TOTAL

>10 Tests per Day 1% 8% 2% 11%

5-10 Tests per Day 2% 6% 3% 11%

2-5 Tests per Day 1% 5% 8% 14%

1-2 Tests per Day 0% 5% 11% 16%

0-1 Tests per Day 0% 7% 41% 48%

TOTAL 4% 31% 65% 100%

Site-level data can be used to identify gaps in testing coverage and target opportunities to use POC to maximize linkage to treatment

15

Market Segmentation by facility level and EID sample volumes

Most sites test only 0-1 patients per day. Some combination of district hospitals and health centers with extremely poor access may be the best use cases for EID POC.

Note: This is sample data from an analysis of 3 high HIV-burden countries in SSA and assumes each HEI should get 2 DNA-PCR tests.

Key Principles of Site Selection

16

1. MOH-led

2. Involvement all key stakeholders to drive consensus

3. Should be driven by the country’s unique diagnostic testing priorities, including such factors as:

a. Patient volumes

b. Access challenges (low-volume sites with long turnaround times and/or sites that are located far from centralized testing labs)

c. Alternative entry points for testing (i.e., pediatric wards for EID)

4. Well documented

CHAI has developed a tool and guidance to aid in identifying the sites best suited for POC

17

Determine parameters for key criteria

The following criteria for scoring sites can be weighted as per country preference:1. Price per test – preference given to sites where cost per test on POC is the lowest2. # of patients covered – preference given to sites with a large number of patients3. “Distance from hub” or “Current turnaround time” – preference given to sites farther away or with long turnaround times

Score and select sites for POC placement

In the CHAI tool, sites are given three scores based on above criteria and can be selected for POC placement of:

1. “EID only” – If POC is used only for EID 2. “VL only” – if POC is used only for VL3. “Both EID/VL” – If POC is used for EID and VLThe tool suggests the best suited product for each site selected, as well as the total cost in first year and annual reagent cost and the impact on coverage for EID and VL.

Understand current testing landscape

o Understand the current gaps in testing coverage in the country: What segments (types of health facilities) have the poorest access to testing? At what level of the health system do most patients seek care? Which segments of the health system would be best served by POC?

Site Selection: Countries map all sites by key criteria and select sites most appropriate for POC diagnostics deployment based on country priorities

Mozambique: Key criteria used to select sites most appropriate for POC diagnostics deployment

Key criteria• Availability of onsite CD4• Patient volumes at each site• Distance from a regional lab• ART coverage rate• CD4 coverage rate• HIV prevalence• Road quality

Country PrioritiesPrioritizing more remote within each province

Kenya: Mapping sites by district to prioritize for POC diagnostics deployment based on key criteria

Potential key criteria• Patient volumes• Access to labs• Others

Site Selection

Implementation

Malawi

• Task force formed by MOH in February 2012 to draft strategy

• Strategy was for CD4, EID, VL, chemistry, hematology, opportunistic infections such as TB, etc.

• Strategy defines POC, provides guidelines andcriteria for selecting products and sites for deployment,and encourages “competition in the marketplace

Includes a roadmap for product-agnostic systems fortraining, quality assurance, supply chain anddistribution, service and maintenance, data management, and M&E

• Strategy approved in June 2012.
