If you’ve spent significant time on a long-term care (LTC) floor, you know the sinking feeling of a mid-shift skin check that reveals an angry, dark red patch on a resident’s sacrum. In this fast-paced environment, the immediate reflex of a floor nurse is often to document this as a pressure injury. But this isn’t always an accurate assessment.
As veteran clinicians know well, the skin can be a deceptive communicator.
Dr. Ritu Saini, our Medical Director of Dermatology, addressed this exact diagnostic trap during our June 2026 Clinical Grand Rounds—When the Skin Speaks: Common Dermatologic Presentations in Older Adults. She reminded our clinical teams of a sobering reality: “Pressure injuries remain a top-reported quality measure and a major source of morbidity and litigation.”
The Administrative and Clinical Fallout
When nursing staff reflexively mislabel incontinence-associated dermatitis (IAD)—a common form of moisture-associated skin damage (MASD)—as a pressure injury, the fallout can be devastating on two fronts. Clinically, the resident receives the wrong intervention; operationally, the facility suffers an unforced error.
Inaccurate pressure injury reporting artificially inflates a facility’s adverse events, directly impacting CMS 5-Star Quality Ratings, inviting aggressive state surveyors, and opening the door to unwarranted legal liability. As Dr. Saini emphasized to our teams, “decubitus ulcers, pressure injuries, obviously that’s a huge issue and a concern and a major source of… not only morbidity but also litigation, liability.”
The Clinical Divergence: Mechanical vs. Chemical
It’s easy to conflate pressure injuries and IAD, since both conditions commonly occur near the sacrum and buttocks. To avoid a misdiagnosis, Dr. Saini’s diagnostic framework demands that clinicians look closer at the etiology:
- The Pressure Injury Profile: A true pressure injury is born from mechanical force (e.g., sustained pressure, shear over bone). Because of this, it presents strictly over bony prominences (e.g., sacrum, heels, ischium, trochanter). Visually, these wounds have distinct edges, often round or regular, and they can penetrate deeply into the tissue—presenting as full-thickness, staged 1-4.
- The Moisture-Associated (IAD) Profile: Moisture damage is born from a hostile chemical environment, and is specifically caused by prolonged moisture (e.g., urine, stool, sweat). Unlike pressure injuries, IAD favors skin folds, the perineum, and between the buttocks—not just over bone. Visually, Dr. Saini notes the damage is “diffuse, ill-defined, often mirror-image.” Further, IAD is “superficial, partial-thickness—not staged.”
The Staging Blind Spot in Darker Skin
One of the most dangerous gaps in LTC dermatology is missing early pressure injuries in non-white residents. When looking for a Stage 1 pressure injury, nurses are traditionally taught to look for “non-blanchable erythema.” But as Dr. Saini explained, in “darker skin, this may be subtle. Look for color, temperature, [and] firmness changes.”
Relying purely on redness can cause you to miss the injury entirely. To avoid this, nurses should use the back of their hand to assess for subtle temperature shifts, and palpate the area to feel for bogginess or induration compared to the surrounding healthy tissue.
Changing the Treatment Trajectory
When a clinician successfully differentiates between pressure injury and IAD, the proper treatment pathway emerges. For a pressure injury, our providers know they must reposition patients to offload pressure, maximizing support surfaces to redistribute pressure. For moisture damage, the directive is “barrier cream, manage incontinence, keep dry.”
At MedElite, we’ve engineered a safeguard against reactionary charting. We teach our teams a shared clinical language, urging them to describe before you diagnose. Dr. Saini summarized this perfectly, explaining that documenting “‘3 cm dusky-red plaque on the left lower leg, warm and tender, present 2 days, no fever,’ beats ‘red leg’.”
By embedding specialized providers directly onto the facility floor, MedElite ensures that these nuanced, high-stakes assessments happen accurately at the bedside—saving facilities from regulatory nightmares and ensuring residents get the proper dignified care they deserve.
