"Adverse Event"

Performance/Reporting Period
2021
QDM Datatype (QDM Version 5.5 Guidance Update):

Data elements that meet criteria using this datatype should document the adverse event and its corresponding value set.

The relevant dateTime references the adverse event occurred.

The author dateTime references the time the adverse event was recorded.

QDM Datatype and Definition

Adverse Event

Adverse Event is used to define any untoward medical occurrence associated with the clinical care delivery, whether or not considered drug related.
Data Elements defined by this QDM Datatype:
QDM Attributes

authorDateTime

The time the data element was entered into the clinical software. Note, some datatypes include both relevant dateTime and author dateTime attributes. When both are present, author dateTime is included to accommodate negation rationale.

The author dateTime addresses when an activity is documented. Documentation can occur at the beginning, during, at the end, or subsequent to the end of the activity. The author dateTime should be used only if the relevantPeriod cannot be obtained or to represent the time negation rationale is documented.

Note: 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.

facilityLocation

The particular locations in a facility in which the diagnostic study or encounter occurs or occurred. Examples include intensive care units (ICUs), nonICUs, burn critical care unit, neonatal ICU, and respiratory care unit. Each "Encounter, Performed" may have one or more locations. For example, a patient treated in multiple locations during an individual encounter might be expressed as:
  • "Encounter, Performed": Inpatient Admission, facility locations
    • ICU (locationPeriod)
    • Non-ICU Admission (locationPeriod)
    • Rehab (locationPeriod)

relevantPeriod

Relevant Period addresses the time between the start of an action to the end of an action. Each datatype using relevant period defines specific definitions for the start and stop time for the action listed.

Note: negation rationale indicates a one-time documentation of a reason an activity is not performed. Negation of QDM datatyperelated actions for a reason always use the author dateTime attribute to reference timing and must not use relevantPeriod

severity

Indicates the intensity of the specified datatype (e.g., persistent, moderate, or severe).

type

The characterization of the reaction (e.g., hypersensitivity, rash, gastroenteric symptoms, etc.).
