Comments

  • The field should be left empty if the source data does not contain a verbatim days_supply, and should not be calculated from other fields. Negative values are not allowed. If the source has negative days supply the record should be dropped as it is unknown if the patient actually took the drug. Several actions are possible -- record is not trustworthy and we remove the record entirely; we trust the record and leave days_supply empty; or record needs to be combined with other record (e.g. reversal of prescription). High values (>365 days) should be investigated. If considered an error in the source data (e.g. typo), the value needs to be excluded to prevent creation of unrealistic long eras.
