15.3 Documentation, CMS Quality Context, and Surveillance

A wound that is not described cannot be trended, defended, or handed off. Evaluation and modification only exist later if today's findings are in the record. This OpenExamPrep section ties CWCN care-planning skills to defensible charting, Centers for Medicare & Medicaid Services (CMS) hospital-acquired condition (HAC) rules that use Present on Admission (POA) indicators, pressure-injury staging that does not reverse, and surveillance methods in the style of the National Database of Nursing Quality Indicators (NDNQI). None of those programs is owned by WOCNCB; they are the quality and payment context in which wound nurses practice.

What a defensible note must let someone reconstruct

Write so a night-shift colleague, a surveyor, or you in six weeks can see the same wound.

A note that says only "wound healing well, continue treatments" is not an evaluation. It is a slogan.

Present on Admission and CMS hospital-acquired conditions

CMS includes Stage 3 and Stage 4 pressure ulcers/injuries that were not present on admission on the inpatient hospital-acquired conditions list. Facilities assign a POA indicator on the claim. Nursing's job is to make the clinical record true:

• Complete a full skin inspection on admission (and on transfer in), including heels, sacrum, devices, and occipital skin.
• Document every existing injury with location, stage, measurements, and photos if policy allows, during that first assessment window.
• A deep-tissue pressure injury or unstageable injury present at the door still needs a timed, dated description even when the HAC category is classically Stage 3 and 4—quality programs track those findings too.
• If a sacral wound is first written on hospital day 4, quality and payment systems will usually treat it as hospital-acquired, even if a family member later says it was there at home. Memory is not POA documentation.

Know the coding nuance without hiding behind it: some coding guidance treats a pressure injury that was POA at a lower stage and then deepened as still related to an injury that began before admission. That nuance does not excuse a missing admission description. You still chart the admission stage and the later stage, the dates, and the clinical response. Wound nurses do not assign the claim indicator, but they create the only evidence coders have.

Do not reverse-stage

NPIAP staging is not a ladder you climb down as granulation fills a crater. A Stage 4 pressure injury that now has a shallow granular bed is a healing Stage 4 (or "Stage 4, healing"), not a Stage 3, 2, or 1. When it is fully epithelialized, it is a healed Stage 4. Reverse-staging understates historical depth, confuses prevalence counts, and can make a serious injury look like a minor one in the quality file. Document improving tissue and smaller measurements; leave the original stage in the name of the injury until closure, then keep the historical stage in the healed label.

NDNQI-style prevalence and incidence

Quality teams still use methods popularized by NDNQI-style prevalence/incidence surveys (training for these surveys is now also offered through NPIAP modules that grew from that tradition). Learn the arithmetic:

• Prevalence is existing pressure injuries at a point in time (or during a short survey window) divided by patients surveyed. It includes injuries that arrived with the patient.
• Incidence is new injuries that developed over a defined period among patients who were at risk and free of that injury at the start.
• Report community-acquired / POA, hospital-acquired, and often unit-acquired separately. A medical unit can have high prevalence from POA injuries and still have low incidence if prevention is working.

Survey method matters: trained teams, a designated day, head-to-toe inspection, agreed staging rules, and no reverse-staging. The wound nurse's role is accurate identification and honest origin (POA versus facility-acquired), not inflating or hiding counts.

Root cause after a hospital-acquired pressure injury

When a facility-acquired Stage 3, Stage 4, unstageable, or deep-tissue injury is identified, a root-cause review asks how intact skin became injured on this team's watch. Typical branches:

• Last documented intact skin and the first documented injury (timeline).
• Braden or other risk subscales that actually failed (mobility, moisture, nutrition, friction/shear, sensory perception, activity).
• Device-related pressure (tubes, collars, oxygen tubing, casts).
• Operating-room or emergency-department time, vasopressors, and hemodynamic instability.
• Support surface ordered versus the surface that was on the bed.
• Turning and offloading that were charted versus what the patient or camera, if used, can corroborate.
• Communication at handoff: was a blanchable reddened heel described as "normal for him"?

The point is prevention redesign, not a hunt for a single nurse to blame. Documentation from the days before the injury is the evidence. If those days say "skin intact" by copy-forward while a device sat on the same ear, the review will not find the truth.

Do not copy stale measurements

Electronic records invite copy-forward. Yesterday's 4.0 × 3.0 × 0.4 cm becomes today's note even though the ulcer is 4.6 × 3.4 × 0.6 cm. Stale numbers hide deterioration, create a false PUSH or PAR trend, and look like falsification in a later review. Enter today's measurements, tissue, and exudate. If you did not measure, write that you did not measure and why—not last week's figures.

Inpatient scenario: Mr. Ruiz and the undocumented sacrum

Mr. Ruiz arrives from home at 22:00 with altered mentation. The night note says "skin warm and dry." On day 3, a wound nurse is consulted for a 3.5 × 3.0 cm sacral Stage 3 injury with slough. The family insists the spot was there last month. For CMS HAC and internal surveillance, the injury was not documented as POA. The team must treat origin as hospital-acquired for quality review, complete a root-cause timeline, photograph with consent, measure, and stop reverse-staging if someone tries to call it a Stage 2 because it "might get smaller." Going forward, admission skin checks need a body diagram with named landmarks, not a three-word phrase.

Legal reality in one sentence

If it was not documented, teams cannot reconstruct the wound—not the size, not the stage, not whether it was present on admission, and not whether the plan ever changed. Evaluation, modification, and surveillance all collapse without a contemporaneous note.
