Specifying sequence number format
In the InForm application, you can configure the format of screening numbers, patient enrollment numbers, and randomization numbers. This section describes the formatting string you must create to specify the format of each of these number types. Specification of numbering formats for screening and enrollment numbers is optional. If you configure the InForm application to generate randomization drug kit numbers, specification of a randomization numbering format is required.
Note: Patient numbers can be automatically generated by the InForm application, using the format that you specify as described in this section, or you can configure the InForm application to enable site personnel to assign patient numbers manually. For information on enabling users to assign manual patient numbers, see Patient numbers.
The format of each type of sequence number can contain fixed text, site name, stratification code, and a sequential number that can also include a text string. These formatting specifications are in the following order:
[SPR]:[string][%[flag][width]type][string]
- SPR—Code that indicates the type of screening, patient enrollment, or randomization number. Codes are not case-sensitive. For details, see Sequence Number Codes.
- string—Text string that appears at the beginning of each generated number.
- %—Required character preceding each flag/width/type specification.
- flag/width/type—A series of specifications that indicates how the InForm application substitutes values in each generated number. You can include multiple flag/width/type specifications, where each specification includes the following values:
- flag—Character that specifies a prefix used to fill in the numerical portion of the sequence number to maintain the number of characters specified in the width variable. For details, see Flag characters.
- width—Minimum number of characters in the numerical portion of the sequence number, to be left-filled by the character specified in the flag variable. This specification is optional.
- type—Code that indicates the inclusion of the site name, stratification code, and sequential number in the sequence number. Codes are not case-sensitive. For details, see Type codes.
- string—Text string added to the end of each generated number.
