What this domain measures
The Skin & Tissue Viability domain captures skin condition and wound care — including pressure injuries (partial-thickness through full-thickness), wounds, and the clinical regime required to prevent or treat skin breakdown. The descriptors turn on whether wounds are responding to treatment and the depth of tissue damage. Severe-level skin needs (non-healing wounds requiring intensive treatment) are a frequent under-scoring battleground.
How it's scored (Annex C wording)
| Level | DST descriptor |
|---|---|
| No needs | No risk of pressure damage or skin condition. |
| Low | Risk of skin breakdown which requires preventative intervention once a day or less than daily without which skin integrity would break down. OR Evidence of pressure damage and/or pressure ulcer(s) either with 'discolouration of intact skin' or a minor wound(s). OR A skin condition that requires monitoring or reassessment less than daily and that is responding to treatment or does not currently require treatment. |
| Moderate | Risk of skin breakdown which requires preventative intervention several times each day without which skin integrity would break down. OR Pressure damage or open wound(s), pressure ulcer(s) with 'partial thickness skin loss involving epidermis and/or dermis', which is responding to treatment. OR An identified skin condition that requires a minimum of daily treatment, or daily monitoring/reassessment to ensure that it is responding to treatment. |
| High | Pressure damage or open wound(s), pressure ulcer(s) with 'partial thickness skin loss involving epidermis and/or dermis', which is not responding to treatment OR Pressure damage or open wound(s), pressure ulcer(s) with 'full thickness skin loss involving damage or necrosis to subcutaneous tissue, but not extending to underlying bone, tendon or joint capsule', which is/are responding to treatment. OR Specialist dressing regime in place; responding to treatment. |
| Severe | Open wound(s), pressure ulcer(s) with 'full thickness skin loss involving damage or necrosis to subcutaneous tissue, but not extending to underlying bone, tendon or joint capsule' which are not responding to treatment and require regular monitoring/reassessment. OR Open wound(s), pressure ulcer(s) with 'full thickness skin loss with extensive destruction and tissue necrosis extending to underlying bone, tendon or joint capsule' or above OR Multiple wounds which are not responding to treatment. |
Evidence that moves the score up
- Wound assessment charts with grade, dimensions, exudate, and tissue type — sequential entries showing trajectory
- Waterlow or Braden risk-assessment scores with dates
- Tissue viability nurse reports and any specialist dressing recommendations
- Repositioning schedule and turns chart — frequency and staff numbers required
- Equipment inventory — air mattress, cushion, heel-protector boots, profiling bed
- Photographs of the wound (where consented) showing change over time
- Antibiotic prescriptions for wound infection and any MRSA/wound-swab results
- Hospital admissions for wound debridement, plastic surgery, or sepsis
How ICBs commonly under-score this domain
Pattern: Assessor scored Moderate because the pressure ulcer is 'healing well'.
Rebuttal: The High descriptor explicitly covers responding-to-treatment full-thickness skin loss involving damage or necrosis to subcutaneous tissue, AND any specialist dressing regime in place that is responding to treatment. A healing wound on a specialist dressing regime is High, not Moderate.
Source: DST Annex C Skin High descriptor
Pattern: Assessor scored High instead of Severe because the wound 'has not deteriorated this month'.
Rebuttal: The Severe descriptor turns on whether the wound is responding to treatment — not on short-term stability. Full-thickness skin loss extending to underlying bone, tendon or joint capsule, OR multiple wounds not responding to treatment, meet Severe regardless of whether the past month has been stable.
Source: DST Annex C Skin Severe descriptor
Pattern: Assessor scored Moderate where the person has multiple concurrent wound sites being managed.
Rebuttal: Multiple concurrent wounds not responding to treatment is itself a Severe-level criterion in the Annex C descriptor table. Where wounds are responding to treatment but a specialist dressing regime is in place, the level is High. Multiple concurrent sites should not be scored Moderate.
