For me I recommend we iterate through the traceability information levels that begins with
- the product traceability and the use of the product master catalog
- incorporate batch/expiry traceability, and then include
- unique item traceability
and use Cases 1-3 with these increasing levels of complexity.
In the future, adding in
- Use Case 5 “Continued Care Institutions” would have good applicability for routine immunizations, patients on ARVs, TB DOTS treatment, and resupply of family planning products.
- Use Case 7 “Falsified Medication Check” to take advantage of the unique item identifiers.
One aspect that is not clear to me in the whitepaper is the “hidden nature” of unique item traceability. While the product and batch information is displayed on secondary and tertiary packaging, there is an implied trust of the serialization on the higher levels of packaging containing a set unique serial numbers within. When I supply a box of vaccines to a ward/facility and scan the associated serial number, I’ll need to also register that all of the doses within also transfer to this location. Personally, I’m interested in an offline scenario for this, especially as we want tight control of returned items for the polio endgame.
@derek.ritz , do you have other aspects that interest you for OHIE-SC consideration?
