Skin Infections in Nursing Homes

Skin infections are not a minor inconvenience in a nursing home. For a frail older adult with thin skin, limited mobility, and a weakened immune system, a reddened patch on the leg or an unhealed pressure injury can become cellulitis, an abscess, a bloodstream infection, or worse within days. The peer-reviewed review Skin and Soft Tissue Infections in the Elderly (PMC10325572) reports that skin and soft tissue infections (SSTIs) account for roughly 17% of healthcare-associated infections in long-term care facilities, compared with about 10.9% in acute care hospitals, and are the third most common infection category in long-term care after respiratory and urinary tract infections.

Federal law treats skin integrity and infection prevention as two distinct but linked quality-of-care obligations. 42 CFR § 483.25(b) requires facilities to prevent avoidable pressure ulcers and to treat existing ones in a way that promotes healing and prevents infection, and 42 CFR § 483.80 requires every facility to maintain an infection prevention and control program. This guide is part of our broader nursing home neglect hub and explains why skin infections occur so often, what the federal rules actually say, what warning signs families can recognize, and how to report concerns.

Why Skin Infections Are Common in Nursing Homes

Aging skin is structurally different from younger skin. According to Skin and Soft Tissue Infections in the Elderly (PMC10325572), the epidermis and dermis atrophy with age, dermal fibroblasts senesce, and collagen synthesis slows. The result is thinner, drier, less elastic skin that tears more easily, heals more slowly, and is less able to act as a barrier against bacteria. The same review reports that SSTIs nearly doubled in adults over 65 between 2000 and 2012, with prevalence ranging from less than 1% to roughly 20% across healthcare settings and averaging about 17% in long-term care.

Pressure injuries are major entry points for infection. The review reports that pressure injury prevalence is under 2% in community-dwelling older adults but rises to about 4.2% in those aged 85 and older, and is substantially higher in hospital-level cohorts. Once the skin is broken, bacteria from the resident's own flora and from the shared facility environment can colonize the wound. Montoya and Mody's peer-reviewed review Common Infections in Nursing Homes (PMC3526889) identifies Streptococcus pyogenes and Staphylococcus aureus, including methicillin-resistant strains, as the most frequent organisms involved in bacterial skin infections in long-term care.

Types of Skin Infections in Long-Term Care

Most skin infections in nursing homes fall into a small number of categories. The PMC10325572 review notes that in European long-term care surveys, bacterial cellulitis, soft tissue, and wound infections account for about 87.4% of SSTIs, followed by fungal infections at 8.3%, herpes simplex and zoster at 2.4%, and scabies at 1.9%.

Cellulitis and erysipelas

Cellulitis is a bacterial infection of the deeper layers of the skin and subcutaneous tissue. According to the peer-reviewed review Cellulitis in older people over 75 years (PMC6906688), the classic local signs are pain, erythema, warmth, and edema, usually with sharply or poorly demarcated borders. The same review reports that the hospitalization rate for cellulitis in adults aged 80 and older is roughly 1,100 per 100,000, compared with 237 per 100,000 in the general population — about 4.6 times higher. More than 25% of older cellulitis patients admitted to hospital live in residential aged care, versus 2.9% of younger cellulitis patients.

Infected pressure injuries and wound infections

Pressure ulcers and other chronic wounds that become infected are a distinct category. The Common Infections in Nursing Homes review (PMC3526889) notes that infected pressure injuries are typically polymicrobial and can involve gram-negative bacilli and anaerobes in addition to Staphylococcus and Streptococcus species. A UK long-term care surveillance dataset cited in the same literature reported a skin and soft tissue infection rate of 1.57 per 1,000 bed-days.

Fungal infections and intertrigo

Intertrigo — inflammation in moist skin folds, often complicated by Candida — is common in long-term care. A multi-center cross-sectional prevalence study by Hahnel et al. (PMC6466768) found that roughly 16.1% of aged nursing home residents had intertrigo (95% CI 11.6–21.2%), meaning about every sixth resident. The submammary fold (9.9%) and inguinal region (9.4%) were the most commonly affected sites.

Scabies and other infestations

Scabies is not technically an infection, but it is a skin condition that frequently causes outbreaks in long-term care. CDC's Public Health Strategies for Crusted Scabies Outbreaks in Institutional Settings describes crusted (Norwegian) scabies as extremely contagious, capable of spreading by brief skin contact and via fomites such as bedding, clothing, furniture, and floors. CDC also notes that scabies is frequently misdiagnosed when itching or rash is absent and is sometimes not recognized in a facility until cases appear among staff — a key reason early surveillance matters. Residents with Methicillin-resistant Staphylococcus aureus colonization also carry higher SSTI risk; our MRSA in nursing homes article covers the MRSA piece in more depth.

Risk Factors in Nursing Home Residents

The same factors that make long-term care residents vulnerable to other neglect harms drive skin infection risk. The Common Infections in Nursing Homes review (PMC3526889) identifies immobility, urinary and fecal incontinence, impaired cognition, and poor nutrition as major risk factors for pressure injuries, which in turn are entry points for infection.

• Immobility and pressure. Residents who cannot reposition themselves develop pressure injuries over bony prominences, and those wounds are frequently the site of subsequent bacterial skin and soft tissue infection.
• Incontinence and moisture. The Critical Review of Incontinence-Associated Dermatitis in Older Adults (PMC12313743) reports that about 45.7% of incontinent nursing home residents develop incontinence-associated dermatitis, and that skin damage can begin within 10–15 minutes of contact with urine or stool because overhydration weakens the stratum corneum.
• Diabetes and peripheral vascular disease. The PMC10325572 review notes that roughly one-third of U.S. adults aged 65 and older have diabetes mellitus, and that diabetic patients face a fourfold increased risk of skin complications — including foot ulcers, cellulitis, and fungal infections — compared with non-diabetics.
• Malnutrition. The same review cites malnutrition prevalence in long-term care facilities ranging from 12.5% to 78.9% depending on the screening tool used. Poor nutrition impairs wound healing and immune response, and is a documented risk factor for both pressure injuries and progression of skin infections.
• Comorbidity burden. The Cellulitis in older people over 75 years review (PMC6906688) found that older nursing home cellulitis patients are significantly more likely than younger patients to have dependent edema, hypertension, atrial fibrillation, dementia, and malignancy — all of which delay healing and increase recurrence.

Federal Care Standards

Two sections of 42 CFR Part 483 carry most of the weight on skin infections, and CMS enforces each through specific F-tags used during survey inspections.

42 CFR § 483.25(b) and F-tag F686 (skin integrity)

42 CFR § 483.25(b)(1) requires that, based on the comprehensive assessment of a resident, the facility must ensure that a resident receives care, consistent with professional standards of practice, to prevent pressure ulcers and does not develop pressure ulcers unless the individual's clinical condition demonstrates that they were unavoidable, and that a resident with pressure ulcers receives necessary treatment and services, consistent with professional standards of practice, to promote healing, prevent infection, and prevent new ulcers from developing. CMS implements this regulation through F-tag F686 (Treatment/Services to Prevent/Heal Pressure Ulcers), which is the surveyor citation used when a facility fails to prevent avoidable pressure injuries or fails to treat existing ulcers in a way that promotes healing and prevents infection.

42 CFR § 483.80 and F-tag F880 (infection control)

42 CFR § 483.80 requires every facility to establish and maintain an infection prevention and control program designed to provide a safe, sanitary, and comfortable environment and to help prevent the development and transmission of communicable diseases and infections. The program must include systems for preventing, identifying, reporting, investigating, and controlling infections, and the facility must designate a qualified infection preventionist. CMS implements these requirements through F-tag F880, which per CMS's Strengthened Enhanced Enforcement for Infection Control Deficiencies guidance is subject to heightened enforcement.

Skin infection prevention sits at the overlap of these two rules. Many of the same concerns that drive skin infections — incontinence care, wound care, and staffing levels — are covered in our related article on poor hygiene in nursing homes.

How Facilities Should Prevent Skin Infections

The core prevention bundle is well defined by federal and peer-reviewed sources. AHRQ's Preventing Pressure Ulcers in Hospitals toolkit and its Safety Program for Nursing Homes: On-Time Pressure Ulcer Prevention call for comprehensive skin assessment on admission, daily, and at transfer or discharge, with risk reassessment whenever condition changes. Prevention bundles include risk assessment, scheduled repositioning, support surfaces, moisture management, and nutritional support.

• Skin assessment and documentation. AHRQ's nursing home pressure ulcer prevention program emphasizes scheduled head-to-toe skin checks with findings documented in the care plan so changes are caught early.
• Incontinence-associated dermatitis prevention. The Critical Review of IAD in Older Adults (PMC12313743) describes gentle no-rinse pH-balanced cleansers, barrier products such as petrolatum or zinc oxide, and prompt change of soiled briefs as the cornerstone of IAD prevention, and notes that structured programs have reduced new IAD incidence to as low as 5.5% in newly incontinent residents.
• Scabies surveillance. CDC's Public Health Strategies for Scabies Outbreaks in Institutional Settings calls for screening new patients and staff for compatible skin findings, prompt skin scrapings when scabies is suspected, contact precautions during care, and washing bedding and clothing in hot water and a hot dryer cycle (temperatures above 122°F / 50°C for 10 minutes kill mites and eggs).
• Wound care protocols. For uncomplicated cellulitis, the IDSA 2014 Practice Guidelines for the Diagnosis and Management of Skin and Soft Tissue Infections recommend a minimum 5-day course of antimicrobial therapy with extension if the infection has not improved.

Warning Signs Families Can Recognize

Families and frequent visitors often see changes before staff do. According to Cellulitis in older people over 75 years (PMC6906688) and the IDSA 2014 SSTI guidelines, the classic local signs of cellulitis are pain, erythema, warmth, and edema, typically with sharply or poorly demarcated borders.

• Redness, warmth, and swelling over an area of skin, especially around a pressure injury, an old wound, or the lower legs.
• Drainage or foul odor from a wound, which can indicate bacterial colonization or abscess formation.
• New confusion, falls, or sudden functional decline. Both PMC10325572 and PMC6906688 emphasize that older adults often present atypically — fever may be absent or blunted, and erythema and warmth may be reduced because of impaired vascular response — so new confusion, decreased mobility, decreased appetite, or sudden functional decline can be the only presenting sign of a serious skin infection in a frail resident.
• Persistent itching or rash in a cluster of residents. CDC notes that scabies in institutional settings is often not recognized until cases appear among staff, so a pattern of unexplained itching across a wing can be an early warning.

Consequences of Untreated Skin Infections

A skin infection that is recognized and treated early is usually controlled. Ignored, it can become life-threatening. The Common Infections in Nursing Homes review (PMC3526889) and Skin and Soft Tissue Infections in the Elderly (PMC10325572) describe infected pressure injuries progressing to cellulitis, osteomyelitis, bacteremia, septicemia, and death, with polymicrobial involvement of gram-negative bacilli and anaerobes.

Invasive Group A streptococcal infections are a particular concern in long-term care. CDC's Group A Strep LTCF Toolkit reports that long-term care residents have a 3- to 8-fold higher incidence of invasive Group A strep infections than community-dwelling older adults and are roughly 1.5 times more likely to die from them, with about 15% of adults 65 and older who develop invasive GAS infection dying. CDC also notes that these infections can rapidly progress within a matter of hours to days.

Necrotizing fasciitis is a deep, rapidly spreading SSTI with high mortality; the IDSA 2014 SSTI guidelines flag rapid progression, bullae, skin sloughing, hypotension, or evidence of organ dysfunction as red flags requiring emergent surgical and antibiotic management, and note that older adults and residents with diabetes, vascular disease, or pressure injuries are disproportionately affected.

A neglected skin infection can also lead to bloodstream spread; for the downstream complication see our sepsis in nursing homes article, and for the worst-case outcome from infected diabetic foot ulcers see amputation in nursing homes. Deeper SSTIs such as abscesses and necrotizing fasciitis are covered in our soft tissue infections companion article.

What Families Should Do

If you suspect a skin infection is being missed, mismanaged, or driven by poor care, the steps below are concrete and consistent with federal reporting pathways.

• Document and photograph. Photograph visible wounds, rashes, drainage, or soiled dressings with a date stamp where possible. Note the date, time, location on the body, and what staff told you when you asked about it.
• Request wound care records. Federal regulations at 42 CFR § 483.10(g)(2) give residents and their authorized representatives the right to access clinical records, including wound care documentation, skin assessments, and incident reports. Ask in writing and keep a copy of the request.
• Escalate inside the facility first. Raise concerns with the charge nurse, then the Director of Nursing. Federal regulations at 42 CFR § 483.10(j) require the facility to designate a Grievance Official and to protect residents from reprisal for raising concerns.
• File with the state survey agency and ombudsman. State survey agencies conduct CMS-directed surveys and can cite F-tags including F686 and F880. The Long-Term Care Ombudsman Program, operated under the federal Older Americans Act and administered by the Administration for Community Living, advocates on behalf of residents and investigates complaints.

State-specific reporting numbers and survey-agency contacts are available in our state guides, including Pennsylvania, Ohio, and Michigan. For cross-cluster context on how skin infection neglect overlaps with abuse reporting pathways, see our nursing home abuse hub.

If you believe a skin infection caused serious harm that may have been preventable and you want to understand legal options outside the regulatory system, you can also speak with an attorney. That conversation is independent of the state survey and ombudsman pathways described above.
