HL7 FHIR Profile: Skin and Wound Assessment, Release 1 (For Comment) (SW) Reference Model Specification

Welcome to the SW Reference Model Documentation
Element Description
BedAreaPercentageByAppearance

The area of the wound that is a specific color out of the total wound bed area (e.g., red 50%, yellow 40%, black 10%). The color is identified using [LOINC: 39132-6]. - LOINC 89255-4 (Wound bed area identified by color/​Area of wound bed)

BedAreaPercentageByColor

The percent of the wound bed appearance is the area of identified wound bed appearance (necrotic, sloughing, etc.; see LOINC 72371-8) compared to the total area of the wound bed. For example, 40% of the wound bed is necrotic. Results can either be subjective or measured. - LOINC 72370-0 (Area of identified wound bed appearance/​Area of wound bed of Wound base)

DateAbated

The date that a condition resolved, went into remission, or was no longer relevant, or the date on which this is expected to occur. This concept is based on the abatement element within the HL7 FHIR Condition Resource. - LOINC 88878-4 (Date of condition abatement)

EvaluationComponent

A simplified, non-separable evaluation consisting of a finding code (represented by the Concept), value (or exception value), reference range, and interpretation. The subject of the evaluation component is the same as in the parent evaluation.

ExceptionValue

Interpretation

Description

IsExudatePresent

Presence or absence of wound drainage. - LOINC 89259-6 (Presence of wound exudate) In Loinc this is a code with Yes, No values

IsPatientReported

Description

IsTunnelingPresent

Tunneling of a wound refers to a narrow opening or pathway underneath the skin that may extend in any direction, resulting in dead space with potential for abscess formation. - LOINC 72298-3 (Tunneling of Wound) In Loinc this is a code with Yes, No values

IsUnderminingPresent

Undermining of a wound refers to tissue destruction that extends under the intact wound edge. The wound is larger at its base (wound bed) than at the skin surface. With pressure ulcers, undermining may be caused by a bacterial infection or associated with osteomyelitis. - LOINC 72295-9 (Undermining of Wound) In Loinc this is a code with Yes, No values

Description

Narrative

A human-readable narrative, potentially including images, that contains a summary of the resource, and may be used to represent the content of the resource to a human.

NarrativeQualifier

Additional information on how the narrative was generated, and the scope of information contained.

ObservationStatement

A base class for representing observed facts, including provenance

ObservedCharacteristic

A coded property.

Odor
  • LOINC 72288-4 (Odor of Exudate from wound)
PanelMembers

PanelMembers represent the elements of a group of a related but independent evaluations. Examples are the measurements that compose a complete blood count (CBC), or the elements of a pathology report. Each member is an independent evaluation, but the grouping reflects a composite lab order, shared specimen, or a single report author. Typically the Category and Reason are not given for individual findings that are part of the panel, but rather given at the level of the panel itself.

PartOf

Description

PeriwoundDescription

A description of the skin around the wound (periwound). Color, induration, warmth and edema should be assessed. Redness of the surrounding skin can be indicative of unrelieved pressure. Irritation of the surrounding skin can result from exposure to feces or urine, a reaction to the dressing or tape, or inappropriate removal of dressing or tape. Redness, tenderness, warmth and swelling are classical clinical signs of infection. [Reference: Brown, P., 2009] - LOINC 72301-5 (Description of Periwound)

PressureUlcerStage

The National Pressure Ulcer Advisory Panel redefined the definition of a pressure ulcer and the stages of pressure ulcers in 2007, including the original 4 stages (Non-blanchable erythema - Stage I, partial thickness – Stage II, full thickness skin loss – Stage III, and full thickness tissue loss – Stage IV) and adding 2 stages on deep tissue injury and unstageable pressure ulcers. As defined by the NPUAP, a pressure ulcer is localized injury to the skin and/or underlying tissue usually over a bony prominence, as a result of pressure, or pressure in combination with shear. - LOINC 72527-5 (Pressure ulcer stage NPUAP)

TopicCode

The concept representing the finding or action that is the topic of the statement. For action topics, the TopicCode represents the action being described. For findings, the TopicCode represents the 'question' or property being investigated. For evaluation result findings, the TopicCode contains a concept for an observable entity, such as systolic blood pressure. For assertion findings, the TopicCode contains a code representing the condition, allergy, or other item being asserted. In all cases, the TopicCode describes the topic of the action or the finding.
