MFR_M07 returns clinical study master records for studies that have scheduled time points directly under the study. It is the query-response companion to MFN_M07.

Use it when a receiver needs to ask for a study schedule on demand and the protocol does not require the separate CM1 phase layer used by MFR_M06.

What workflow it represents

A consuming system queries for a simpler study schedule. The owner responds with the study definition and its direct scheduled time points.

The message is useful for cache repair, targeted study setup, or systems that do not subscribe to unsolicited study master-file updates.

How to read the structure

MSH identifies the response. MSA acknowledges the query, and optional QAK can report query status and hit counts. QRD and QRF carry the original-style query context.

MFI identifies the clinical study without phases master file. Each MF_QUERY group returns MFE, required CM0, and optional repeating CM2 schedule records. DSC appears when more response pages are available.

Implementation traps

The main trap is choosing the wrong study shape. If phases are operationally meaningful, use the M06 pattern. If the schedule truly belongs directly to the study, M07 is simpler and easier to read.

Do not use display text as the schedule key. Baseline and follow-up labels are common across many studies; the identifier and study context keep them from colliding.

As with other MFR responses, continuation matters. A partial response should not be treated as a complete study schedule.

Reference notes

HL7 master-file query material describes MFQ/MFR as the query and response transaction for master-file records. MFR_M07 returns clinical study records with CM0 and direct CM2 schedule rows.
