CM1 segment

The Technical Steward for the CM1 segment is ORDERS. Each Clinical Study Phase Master (CM1) segment contains the information about one phase of a study identified in the preceding CM0. This is an optional structure to be used if the study has more than one treatment or evaluation phase within it. The identification of study phases that the patient enters are sent in the CSP segment: sequence 2. The CM1 segment describes the phase in general for the receiving system. 8.11.3.0 CM1 Field Definitions

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 CM1-3 and its value arrives as CM1-2, so the receiver stores Description of Study Phase as Study Phase Identifier.

This page carries the CM1 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 CM1.
