9.2 Resource Condition - Content

Patient Care Work GroupMaturity Level: 3 Trial UseCompartments: Encounter, Patient, Practitioner, RelatedPerson

A clinical condition, problem, diagnosis, or other event, situation, issue, or clinical concept that has risen to a level of concern.

Condition is one of the event resources in the FHIR workflow specification.

This resource is used to record detailed information about a condition, problem, diagnosis, or other event, situation, issue, or clinical concept that has risen to a level of concern. The condition could be a point in time diagnosis in context of an encounter, it could be an item on the practitioner’s Problem List, or it could be a concern that doesn’t exist on the practitioner’s Problem List. Often times, a condition is about a clinician's assessment and assertion of a particular aspect of a patient's state of health. It can be used to record information about a disease/illness identified from application of clinical reasoning over the pathologic and pathophysiologic findings (diagnosis), or identification of health issues/situations that a practitioner considers harmful, potentially harmful and may be investigated and managed (problem), or other health issue/situation that may require ongoing monitoring and/or management (health issue/concern).

The condition resource may be used to record a certain health state of a patient which does not normally present a negative outcome, e.g. pregnancy. The condition resource may be used to record a condition following a procedure, such as the condition of Amputee-BKA following an amputation procedure.

While conditions are frequently a result of a clinician's assessment and assertion of a particular aspect of a patient's state of health, conditions can also be expressed by the patient, related person, or any care team member. A clinician may have a concern about a patient condition (e.g. anorexia) that the patient is not concerned about. Likewise, the patient may have a condition (e.g. hair loss) that does not rise to the level of importance such that it belongs on a practitioner’s Problem List.

For example, each of the following conditions could rise to the level of importance such that it belongs on a problem or concern list due to its direct or indirect impact on the patient’s health. These examples may also be represented using other resources, such as FamilyMemberHistory, Observation, or Procedure.

  • Unemployed
  • Without transportation (or other barriers)
  • Susceptibility to falls
  • Exposure to communicable disease
  • Family History of cardiovascular disease
  • Fear of cancer
  • Cardiac pacemaker
  • Amputee-BKA
  • Risk of Zika virus following travel to a country
  • Former smoker
  • Travel to a country planned (that warrants immunizations)
  • Motor Vehicle Accident
  • Patient has had coronary bypass graft

The condition resource may be referenced by other resources as "reasons" for an action (e.g. MedicationRequest, Procedure, ProcedureRequest, etc.)

This resource is not typically used to record information about subjective and objective information that might lead to the recording of a Condition resource. Such signs and symptoms are typically captured using the Observation resource; although in some cases a persistent symptom, e.g. fever, headache may be captured as a condition before a definitive diagnosis can be discerned by a clinician.

Use the Observation resource when a symptom is resolved without long term management, tracking, or when a symptom contributes to the establishment of a condition.

Use Condition when a symptom requires long term management, tracking, or is used as a proxy for a diagnosis or problem that is not yet determined.

When the diagnosis is related to an allergy or intolerance, the Condition and AllergyIntolerance resources can both be used. However, using Condition alone is not sufficient as the allergy or intolerance needs to be represented as an AllergyIntolerance to be actionable for decision support

This resource is referenced by AdverseEvent, Appointment, CarePlan, CareTeam, Claim, ClinicalImpression, Communication, CommunicationRequest, Encounter, EpisodeOfCare, ExplanationOfBenefit, FamilyMemberHistory, Goal, MedicationAdministration, MedicationRequest, MedicationStatement, Procedure, ProcedureRequest, ReferralRequest, RiskAssessment and VisionPrescription

  • con-1: On Condition.stage: Stage SHALL have summary or assessment (expression on Condition.stage: summary.exists() or assessment.exists())
  • con-2: On Condition.evidence: evidence SHALL have code or details (expression on Condition.evidence: code.exists() or detail.exists())
  • con-3: Condition.clinicalStatus SHALL be present if verificationStatus is not entered-in-error (expression : verificationStatus='entered-in-error' or clinicalStatus.exists())
  • con-4: If condition is abated, then clinicalStatus must be either inactive, resolved, or remission (expression : abatement.empty() or (abatement as boolean).not() or clinicalStatus='resolved' or clinicalStatus='remission' or clinicalStatus='inactive')

Many of the code systems used for coding conditions will provide codes that define not only the condition itself, but may also specify a particular stage, location, or causality as part of the code. This is particularly true if SNOMED CT is used for the condition, and especially if expressions are allowed.

The Condition.code may also include such concepts as "history of X" and "good health", where it is useful or appropriate to make such assertions. It can also be used to capture "risk of" and "fear of", in addition to physical conditions, as well as "no known problems" or "negated" conditions (e.g., "no X" or "no history of X" - see the following section for "No Known Problems" and Negated Conditions).

When the Condition.code specifies additional properties of the condition, the other properties are not given a value - instead, the value must be understood from the Condition.code.

Conditions/Problems Not Reviewed, Not Asked

When a sending system does not have any information about conditions/problems being reviewed or the statement is about conditions/problems not yet being asked, then the List resource should be used to indicate the List.emptyReason.code="notasked".

Conditions/Problems Reviewed, None Identified

Systems may use the List.emptyReason when a statement is about the full scope of the list (i.e. the patient has no conditions/problems of any type). However, it may be preferred to use a code for "no known problems" (e.g., SNOMED CT: 160245001 |No current problems or disability (situation)|), so that all condition/problem data will be available and queryable from Condition resource instances.

Also note that care should be used when adding new Condition resources to a list to ensure that any negation statements that are voided by the addition of a new record are removed from the list. E.g. If the list contains a "no known problems" record and you add a "diabetes" condition record, then be sure that you remove the "no known problems" record.

STU Note: There are two primary ways of reporting "no known problems" in the current specification: using the CodeableConcept, as described above, or using the List resource with emptyReason. During the STU period, feedback is sought regarding the preferred approach.

Patient Denies Condition

When the patient denies a condition, that can be annotated in the Condition.note element.

Generally, electronic records do not contain assertions of conditions that a patient does not have. There are however two exceptions:

  • It is appropriate to capture a "refuted" Condition record if the patient or anyone else had reason to believe that a patient did have a condition for a period of time and subsequent evidence has demonstrated that belief was mistaken. In this case, a concrete statement acknowledging the belief as well as the refutation of it is useful.
  • It is common as part of checklists prior to admission, surgery, enrollment in trials, etc. to ask questions such as "are you pregnant", "do you have a history of hypertension", etc. This information should NOT be captured using the Condition resource but should instead be captured using QuestionnaireResponse or Observation. In this case, the combination of the question and answer would convey that a particular condition was not present.

The Condition.evidence provides the basis for whatever is present in Condition.code.

A range is used to communicate age period of subject at time of abatement.

If the data enterer is different from the asserter and needs to be known, this could be captured using a Provenance instance pointing to the Condition. For example, it is possible that a nurse records the condition on behalf of a physician. The physician is taking responsibility, despite the nurse entering it into the medical record.

The Condition.stage and Condition.clinicalStatus may have interdependencies. For example, some "stages" of cancer, etc. will be different for a remission than for the initial occurrence.

A known issue exists with circular references between Condition and ClinicalImpression, which is due to the low maturity level of ClinicalImpression. The Patient Care work group intends to address this issue when ClinicalImpression is considered substantially complete and ready for implementation.
