This is an old revision of the document!


Remove days_supply field

  • Requester: Klaus Bonadt, Christian Reich, Patrick Ryan
  • Discussion: here.

Proposal

If the days_supply and the drug_exposure_end_date fields essentially designate the same thing they are therefore duplicates of the same information and create the danger of of inconsistency. One of them could be dropped.

Alternatively, we could split them into two different meanings:

FieldRequiredTypeDescription
drug_exposure_end_dateNodateThe end date for the current instance of Drug utilization. It is not available from all sources.
days_supplyNointegerThe number of days of supply of the medication as recorded in the original prescription or dispensing record.

Use Cases

All standardized analytics and the drug era constructor will only use the drug_exposure_end_date. The days supply could be used to understand the intent of prescribing versus the reality, and it could be used to calculate MPR.
