Why Pressure Ulcer Measurements Matter in Nursing Home Neglect Cases

In a nursing home pressure ulcer case, a few centimeters can tell an important story.

Facilities generally document pressure injuries by recording their length, width, and depth. Nurses may also document tunneling, undermining, drainage, odor, tissue type, wound edges, and the condition of the surrounding skin. These measurements are not merely clinical details. When reviewed over time, they can show whether a wound was improving, remaining unchanged, or becoming progressively worse.

For families and referring attorneys investigating a possible nursing home neglect case, the wound-measurement history is often one of the most important parts of the medical record.

Pressure Ulcer Measurements Create a Timeline

A single wound measurement provides only a snapshot. A series of measurements creates a timeline.

Suppose a resident’s sacral wound was documented as measuring two centimeters across when first identified. Two weeks later, it measured five centimeters and had developed measurable depth and undermining. That progression raises questions that cannot be answered merely by looking at the wound’s final stage:

• Was the resident repositioned as required?
• Was an appropriate pressure-relieving mattress provided?
• Were nutrition and hydration problems identified and treated?
• Did the facility notify the physician when the wound deteriorated?
• Was the treatment plan changed when the original interventions failed?

Federal guidance recognizes that wound progress should be evaluated over time. AHRQ wound-assessment materials instruct clinicians to measure the wound’s longest and widest dimensions, assess depth, and evaluate features such as undermining and necrotic tissue. Measurements therefore help caregivers determine whether treatment is working and whether additional intervention is necessary.

Length and Width Do Not Tell the Entire Story

Nursing home records sometimes focus on surface dimensions while minimizing what is happening underneath the skin. That can be misleading.

A pressure ulcer with a relatively small opening may extend deeply into tissue. It may also contain tunneling or undermining beneath apparently intact skin. “Tunneling” refers to a channel extending from the wound into surrounding tissue. “Undermining” occurs when tissue destruction extends underneath the wound’s edges.

These conditions may make the true injury substantially larger than the visible opening suggests. They can also complicate wound packing, increase the risk of infection, and indicate extensive tissue destruction.

For that reason, an investigation should not stop with length multiplied by width. It should examine:

• Depth at the deepest measurable point;
• The location and extent of any undermining;
• The length and direction of any tunnels;
• The presence of slough or eschar;
• Drainage amount, color, and odor;
• Exposed muscle, tendon, or bone; and
• Redness, warmth, swelling, or other changes around the wound.

Inconsistent Measurements May Reveal Documentation Problems

Pressure ulcer measurements are not always consistent. Different nurses may use different techniques. One person may measure the longest dimension, while another measures from head to toe. Some measurements may be taken before debridement and others afterward. A wound obscured by dead tissue may also appear deeper once that tissue is removed.

These explanations must be considered. But dramatic or unexplained changes can also expose unreliable charting.

Warning signs include identical measurements repeated week after week, measurements that suddenly become smaller despite descriptions of worsening tissue, missing measurements during critical periods, or conflicting descriptions by the wound nurse and bedside staff. A chart may report that a wound is “improving” even though its surface area, depth, drainage, or necrotic tissue is increasing.

When records conflict, the investigation should identify who actually examined the wound, who entered the measurement, when the entry was made, and whether any entry was copied forward from an earlier note.

Photographs Should Be Compared With the Written Chart

Many facilities or outside wound-care companies photograph pressure ulcers. Those photographs should be obtained in their original form whenever possible.

A photograph may reveal that the wound was substantially worse than the written note suggests. It may also establish that a photograph assigned to one date was actually taken on another date. Original image files may contain metadata identifying when the photograph was created or modified.

The photographs should be compared against wound sheets, treatment administration records, physician orders, weekly skin assessments, Minimum Data Set assessments, hospital records, and billing records. If a wound-care provider billed for an evaluation that does not appear in the chart, that discrepancy may lead to additional records.

Measurements Can Show When the Facility Should Have Escalated Care

Wound measurements matter because they should prompt action. A deteriorating wound may require changes to repositioning, pressure relief, nutrition, wound products, debridement, laboratory testing, antibiotics, or the level of medical supervision.

A growing wound may also require notification of the attending physician and the resident’s representative. If the facility continued the same ineffective treatment while measurements showed progressive deterioration, the issue is not simply poor documentation. It may reflect a failure to respond to a significant change in condition.

The sequence is often critical: when did the wound begin worsening, who knew about the change, what was communicated, and how long did the facility wait before taking action?

How We Investigate Pressure Ulcer Measurements

A meaningful pressure ulcer investigation requires more than locating the largest number in the chart. The measurements should be organized chronologically and compared with changes in staffing, repositioning documentation, nutrition, physician orders, treatment records, infection indicators, and hospital transfers.

At Kevin Etzkorn Law, we investigate serious pressure ulcer and nursing home neglect cases throughout Missouri. We work to determine not only how large a wound became, but what the facility knew as it worsened and whether timely interventions could have prevented the injury.
