We don’t record the number of visits. Each visit is recorded as an encounter, so no need to record the number of visits. The only situation where we record multiple occurrences of an event – collecting the chemotherapy cycle number (question/numeric).
Wondering if you are anticipating the addition of two more members: 1) vaccination lot number and 2) vaccination lot expiry date in order to comply (at least in part) with ‘The Drug Supply Chain Security Actand 2D Vaccine Barcodes’ (CDC ref. here) and to enable “tracking and tracing”.
@mksd Yes. It would be easy to modify the convset to include lot number and expiration date.
If you look at Immunization History (CIEL:1421) concept, it already includes lot number, and manufacturer. @akanter might consider adding the lot expiry date to the same construct, unless this would be modeled differently with the lot number as a key to other data (expiry date and manufacturer).
As for CIEL:984, it doesn’t need to be class=ConvSet, but that’s how it is in CIEL, but it works with coded datatype. I would have made it class=Drug.
