Duration of Drug Administration (number)

Usually, the duration of drug administration is calculated from the start date and end date of administration. However, more detailed information on duration, such as in minutes or hours, may be helpful. This data element is also used when the exact dates of administration are not known at the time of reporting, but information on the duration of administration is available. In such cases, one of the date data elements (start date or end date) and this data element should be entered. The information required here is the total duration of administration, including any intermittent administration periods. This data element is used to enter the value (number) for the duration of administration.
