Duration Formats
This screen is used to create/view/edit the Duration Formats lookups. These are used to set how a patient's age is presented and allows the format to vary as a function of age. Normally only one is needed and it is used to set the values in the 'Patient Age Format' field on the Administration|Organisations|Practice screen.
The fields are as follows:
Name - the name of the format
Active - uncheck the box to deactivate the format
Formats tab - its fields are as follows:
Interval - sets the (inclusive) age (in units of Units) below which this format is to be used (ie less than or equal to 3 years in the above example)
Units - can be years, months, days or weeks
Show Years/Months/Weeks/Days - check the boxes to display the years/months/weeks/days
Note that when adding formats, these can be added in any order. The last entry (999 years) provides the setting for the more than 3 years case. If no 'Patient Age Format' is set for the Practice, then the formats used are as follows:
| Age | Shown as |
|---|---|
| < 7 days | N day(s) |
| < 90 days | N week(s) |
| < 23 months | N month(s) |
| < 2 years | N year(s) |
| else | N years |
If the age is greater than that set for the largest defined interval, then the above table is used to define the format.
Note that no rounding is done. That is, with the default settings, a patient aged 1 year, 11 months will be shown as '1 Year' rather that '2 Years'.
