CSS segment

The Clinical Study Data Schedule (CSS) segment is optional depending on whether messaging of study data needs to be linked to the scheduled data time points for the study. (See Section 7.6.1.3, “data schedule.”) The CSS segment enables communication of data schedules and adherence that ranges from the basic to the elaborate. Use of the segment must be planned for each implementation. Each CSS segment will subsume observation and drug administration segments that follow, indicating that they satisfy this scheduled time point.

required optional

Count the pipes to find a field, and count the empty ones too: an empty field still holds its place. Leave out the separator before CSS-2 and its value arrives as CSS-1, so the receiver stores Study Scheduled Patient Time Point as Study Scheduled Time Point.

This page carries the CSS field table as published and nothing beyond it. The field notes, vendor behaviour, FHIR mapping and parsing guidance that thePID page has are still to be written for CSS.
