9.2 Resource Condition - Content

Patient Care Work Group Maturity Level : 3   Trial Use Security Category : Patient Compartments : 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.

9.2.1 Scope and Usage

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

9.2.2 Boundaries and Relationships

The condition resource may be referenced by other resources as "reasons" "reasons" for an action (e.g. MedicationRequest , Procedure , ProcedureRequest ServiceRequest , 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. By contrast, headache may be captured as an Observation when it contributes to the establishment of a meningitis Condition.

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, to be actionable for decision support, using Condition alone is not sufficient as the allergy or intolerance condition 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 , Contract , CoverageEligibilityRequest , DeviceRequest , DeviceUseStatement , Encounter , EpisodeOfCare , ExplanationOfBenefit , FamilyMemberHistory , Goal , GuidanceResponse , ImagingStudy , Immunization , MedicationAdministration , MedicationRequest , MedicationStatement , Procedure , ProcedureRequest , ReferralRequest RequestGroup , RiskAssessment , ServiceRequest and VisionPrescription SupplyRequest

9.2.3.1 Terminology Bindings

Path Definition Type Reference
Condition.clinicalStatus The clinical status of the condition or diagnosis. Required Condition Clinical Status Codes ConditionClinicalStatusCodes
Condition.verificationStatus The verification status to support or decline the clinical status of the condition or diagnosis. Required ConditionVerificationStatus
Condition.category A category assigned to the condition. Example Extensible Condition Category Codes ConditionCategoryCodes
Condition.severity A subjective assessment of the severity of the condition as evaluated by the clinician. Preferred Condition/Diagnosis Severity Condition/DiagnosisSeverity
Condition.code Identification of the condition or diagnosis. Example Condition/Problem/Diagnosis Codes Condition/Problem/DiagnosisCodes
Condition.bodySite Codes describing anatomical locations. May include laterality. Example SNOMED CT Body Structures SNOMEDCTBodyStructures
Condition.stage.summary Codes describing condition stages (e.g. Cancer stages). Example Condition Stage ConditionStage
Condition.stage.type Codes describing the kind of condition staging (e.g. clinical or pathological). Example ConditionStageType
Condition.evidence.code Codes that describe the manifestation or symptoms of a condition. Example Manifestation and Symptom Codes ManifestationAndSymptomCodes

9.2.3.2 Constraints

id Level Location Description Expression
con-1 : On Condition.stage: Rule Condition.stage Stage SHALL have summary or assessment ( expression on Condition.stage: summary.exists() or assessment.exists() )
con-2 : On Condition.evidence: Rule Condition.evidence evidence SHALL have code or details ( expression on Condition.evidence: code.exists() or detail.exists() )
con-3 : Guideline (base) Condition.clinicalStatus SHALL be present if verificationStatus is not entered-in-error ( expression and category is problem-list-item : verificationStatus='entered-in-error' or clinicalStatus.exists() or verificationStatus.coding.where(system='http://terminology.hl7.org/CodeSystem/condition-ver-status' and code = 'entered-in-error').exists() or category.select($this='problem-list-item').empty() )
This is (only) a best practice guideline because:

Most systems will expect a clinicalStatus to be valued for problem-list-items that are managed over time, but might not need a clinicalStatus for point in time encounter-diagnosis.

con-4 : Rule (base) If condition is abated, then clinicalStatus must be either inactive, resolved, or remission ( expression : abatement.empty() or (abatement as boolean).not() clinicalStatus.coding.where(system='http://terminology.hl7.org/CodeSystem/condition-clinical' and (code='resolved' or clinicalStatus='resolved' code='remission' or clinicalStatus='remission' code='inactive')).exists()
con-5 Rule (base) Condition.clinicalStatus SHALL NOT be present if verification Status is entered-in-error verificationStatus.coding.where(system='http://terminology.hl7.org/CodeSystem/condition-ver-status' and code='entered-in-error').empty() or clinicalStatus='inactive' clinicalStatus.empty() )

9.2.3.3 Use of Condition.code

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

9.2.3.4 "No "No Known Problems" Problems" and Negated Conditions

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". 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 "no known problems" 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 "no known problems" problems" record and you add a "diabetes" "diabetes" condition record, then be sure that you remove the "no "no known problems" problems" record.

STU Trial-Use Note: There are two primary ways of reporting "no "no known problems" 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.

Provide feedback here .

Patient Denies Condition

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

9.2.3.5 Assertions of Condition Absence

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" "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 "are you pregnant", "do pregnant", "do you have a history of hypertension", 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.

9.2.3.6 Use of Condition.evidence

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

9.2.3.7 Use of Condition.abatementRange

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

9.2.3.8 Use of Condition.asserter

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.

9.2.3.9 Use of Condition.clinicalStatus

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

9.2.3.10 Diagnosis Role and Rank within an Encounter

To represent the role of the diagnosis within an encounter, such as admission diagnosis or discharge diagnosis, use Encounter.diagnosis.role .

To represent the numeric ranking of the diagnosis within an encounter, such as primary, secondary, or tertiary, use Encounter.diagnosis.rank .

9.2.3.11 Known Issue

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.
