["Procedure, Performed": "Gastric Bypass Surgery"]

Data elements that meet criteria using this datatype should document the completion of the procedure indicated by the QDM category and its corresponding value set.

Timing:

• relevant dateTime references the time the procedure is performed when the procedure occurs at a single point in time.
• relevantPeriod references a start and stop time for a procedure that occurs over a time interval. relevantPeriod addresses:
  • startTime - The time the procedure begins.
  • stopTime - The time the procedure ends.
• author dateTime references the time the action was recorded.
• Refer to the eCQM expression to determine allowable timings to meet measure criterion.

Notes: 

• Timing refers to a single instance of a procedure. If a measure seeks to evaluate multiple procedures over a period of time, the measure developer should use CQL logic to represent the query request.
• The incision dateTime is a single point in time available from the Operating Room and/or Anesthesia Record.
• negation rationale indicates a one-time documentation of a reason an activity is not performed. Negation of QDM datatype-related actions for a reason always use the author dateTime attribute to reference timing and must not use relevantPeriod.
• See section 6.4 for guidance about differentiating between successful and unsuccessful procedures.
