An event (i.e. any change to current patient status) that may be related to unintended effects on a patient or research participant. The unintended effects may require additional monitoring, treatment, hospitalization, or may result in death. The AdverseEvent resource also extends to potential or avoided events that could have had such effects. There are two major domains where the AdverseEvent resource is expected to be used. One is in clinical care reported adverse events and the other is in reporting adverse events in clinical research trial management. Adverse events can be reported by healthcare providers, patients, caregivers or by medical products manufacturers. Given the differences between these two concepts, we recommend consulting the domain specific implementation guides when implementing the AdverseEvent Resource. The implementation guides include specific extensions, value sets and constraints.

If the element is present, it must have either a @value, an @id, or extensions Business identifiers assigned to this adverse event by the performer or other systems which remain constant as the resource is updated and propagates from server to server. The current state of the adverse event or potential adverse event. Whether the event actually happened or was a near miss. Note that this is independent of whether anyone was affected or harmed or how severely. The overall type of event, intended for search and filtering purposes. Specific event that occurred or that was averted, such as patient fall, wrong organ removed, or wrong blood transfused. This subject or group impacted by the event. The Encounter associated with the start of the AdverseEvent. The date (and perhaps time) when the effect of the AdverseEvent occurred. Estimated or actual date the AdverseEvent began, in the opinion of the reporter. The date on which the existence of the AdverseEvent was first recorded. Information about the condition that occurred as a result of the adverse event, such as hives due to the exposure to a substance (for example, a drug or a chemical) or a broken leg as a result of the fall. The information about where the adverse event occurred. Assessment whether this event, or averted event, was of clinical importance. Describes the type of outcome from the adverse event, such as resolved, recovering, ongoing, resolved-with-sequelae, or fatal. Information on who recorded the adverse event. May be the patient or a practitioner. Indicates who or what participated in the adverse event and how they were involved. The research study that the subject is enrolled in. Considered likely or probable or anticipated in the research study. Whether the reported event matches any of the outcomes for the patient that are considered by the study as known or likely. Describes the entity that is suspected to have caused the adverse event. The contributing factors suspected to have increased the probability or severity of the adverse event. Preventive actions that contributed to avoiding the adverse event. The ameliorating action taken after the adverse event occurred in order to reduce the extent of harm. Relevant past history for the subject. In a clinical care context, an example being a patient had an adverse event following a penicillin administration and the patient had a previously documented penicillin allergy. In a clinical trials context, an example is a bunion or rash that was present prior to the study. Additionally, the supporting item can be a document that is relevant to this instance of the adverse event that is not part of the subject's medical history. For example, a clinical note, staff list, or material safety data sheet (MSDS). Supporting information is not a contributing factor, preventive action, or mitigating action. Comments made about the adverse event by the performer, subject or other participants.

The implementation guides include specific extensions, value sets and constraints. Distinguishes the type of involvement of the actor in the adverse event, such as contributor or informant. Indicates who or what participated in the event. An event (i.e. any change to current patient status) that may be related to unintended effects on a patient or research participant.

The implementation guides include specific extensions, value sets and constraints. Identifies the actual instance of what caused the adverse event. May be a substance, medication, medication administration, medication statement or a device. Information on the possible cause of the event. The date (and perhaps time) when the suspect entity occurred. An event (i.e. any change to current patient status) that may be related to unintended effects on a patient or research participant.

Given the differences between these two concepts, we recommend consulting the domain specific implementation guides when implementing the AdverseEvent Resource. The implementation guides include specific extensions, value sets and constraints. The method of evaluating the relatedness of the suspected entity to the event. The result of the assessment regarding the relatedness of the suspected entity to the event. The author of the information on the possible cause of the event.
