When a loved one becomes less mobile, after surgery, a stroke, advanced Parkinson’s, or simply with age, one of the most preventable complications also becomes one of the most dangerous: pressure injuries, sometimes called bedsores or pressure ulcers. They can develop in a matter of hours, take months to heal, and in their advanced stages they can expose muscle and bone. In Phoenix neighborhoods like Arcadia and across Tempe, families caring for an older parent at home often don’t realize how quickly a small reddened spot on the heel or tailbone can turn into a wound requiring weeks of specialized nursing care.
Pressure injuries affect between 1 and 3 million Americans every year, and treating them costs an estimated $26.8 billion annually. Prevalence in home care settings ranges from roughly 4.5% to over 17%, depending on the population studied. The good news for Phoenix-area families is that most pressure injuries are preventable when caregivers know what to look for and follow a consistent prevention plan, and when a Registered Nurse is involved early.
This guide walks through what pressure injuries are, the risk factors that matter most for older adults at home in Phoenix, prevention strategies that work, when to call a skilled nurse, and the local resources available to families navigating wound care.
What Is a Pressure Injury (and Why “Bedsore” Doesn’t Capture It)
The National Pressure Injury Advisory Panel (NPIAP) updated the term from “pressure ulcer” to “pressure injury” in 2016, because skin damage doesn’t always involve an open ulcer. A pressure injury is localized damage to skin and underlying tissue, usually over a bony area, heel, tailbone (sacrum), hip, shoulder blade, elbow, or back of the head, or under a medical device such as oxygen tubing, a brace, or a catheter.
NPIAP describes six categories. Stage 1 is nonblanchable redness of intact skin. Stage 2 is partial-thickness skin loss with exposed dermis. Stage 3 is full-thickness loss with visible fat. Stage 4 exposes muscle, tendon, or bone. “Unstageable” injuries are covered by slough or eschar, so the true depth can’t be seen until the wound is cleaned. Deep tissue injuries appear as purple or maroon discoloration of intact skin and often signal hidden damage underneath. The heel and sacrum are the most common sites in older adults.
Who’s at Highest Risk at Home
Risk factors most relevant to seniors in Phoenix, Arcadia, and Tempe include:
- Limited mobility (bed-bound, chair-bound, post-surgical recovery, advanced Parkinson’s or dementia)
- Incontinence and increased skin moisture
- Poor nutrition or recent unintentional weight loss
- Diabetes or vascular disease (reduced blood flow to the skin)
- Advanced age and thin, fragile skin
- Cognitive impairment that prevents the patient from shifting position or reporting discomfort
- Previous pressure injury (the strongest predictor of a new one)
Clinicians use the Braden Scale to estimate risk across six areas: sensory perception, moisture, activity, mobility, nutrition, and friction/shear. A trained RN can complete this assessment on the first home visit and update it as the patient’s condition changes.
Prevention That Actually Works at Home
Pressure injury prevention is built on a handful of habits, performed consistently:
- Reposition every two hours in bed and every hour in a chair. Done well, this single habit reduces pressure injury incidence by up to 50%.
- Inspect skin twice daily, especially over heels, sacrum, hips, elbows, shoulder blades, back of the head, and ears.
- Float heels off the bed using a pillow under the calves so the heels touch nothing.
- Keep skin clean and dry; respond to incontinence promptly with gentle cleansing and a barrier cream.
- Use a pressure-redistributing mattress overlay or chair cushion for at-risk patients.
- Hydrate well and prioritize protein, 1.2 to 1.5 grams per kilogram of body weight per day for those at risk of skin breakdown.
- Document with dated photos so changes are visible to the nurse and physician across visits.
One thing not to do: never massage a reddened area. It worsens deep-tissue damage rather than relieving pressure.
When You Need Skilled Wound Nursing
A Stage 1 redness that doesn’t fade after pressure is relieved is the earliest warning sign and warrants nursing evaluation. Any open wound, Stage 2 and beyond, unstageable injuries, or suspected deep tissue injury, requires a skilled nurse. So does any wound that shows signs of infection (warmth, drainage, foul odor, fever) or that hasn’t improved in two weeks.
Skilled wound nursing includes measurement and staging of the wound, selection of the right dressing for the current stage (transparent films, hydrocolloids, foams, alginates, antimicrobials), debridement when appropriate, infection monitoring, and direct coordination with the patient’s physician or wound care specialist. Family caregivers shouldn’t be doing this alone, the product choices change as the wound changes, and one wrong dressing can set healing back weeks.
How RN-Supervised Home Care Helps
At BrightStar Care of Phoenix NW/NE and Tempe, a Registered Nurse performs the first home assessment, builds the care plan, and oversees every visit, including skin checks, dressing changes, and ongoing wound documentation. The RN communicates with the patient’s physician about wound trajectory and adjusts the plan as healing progresses or stalls.
Because there is no minimum hour requirement, families can start with a few weekly skilled nursing visits for dressing changes and skin assessment, then scale up or add personal care as needs change. Every direct-care caregiver holds a Level 1 Arizona fingerprint clearance card. The agency is state licensed, has been Joint Commission Accredited, and is locally owned and operated in Phoenix.
Phoenix-Specific Context: Heat, Dehydration, and Skin
Phoenix’s extreme heat creates two pressure-injury risk factors that families often don’t see coming. First, even mild dehydration reduces skin elasticity and tissue oxygenation, accelerating breakdown. Summer temperatures routinely exceed 110°F in Phoenix, Arcadia, and Tempe, and homebound older adults frequently don’t drink enough. Second, sweating leads to skin maceration, waterlogged, soft skin that breaks down under pressure far faster than dry skin does.
Air conditioning helps, but it isn’t the whole answer. During summer months, caregivers should increase fluid intake (when not restricted by the physician), time any outdoor activity for early morning, and inspect skin folds and bony prominences twice daily. Maricopa County, which encompasses Phoenix and Tempe, has one of the largest older-adult populations in the Southwest, making pressure-injury prevention a community-scale concern.

Frequently Asked Questions
How quickly can a pressure injury form?
Faster than most families expect. In a person with poor circulation, limited mobility, or fragile skin, tissue damage can begin in as little as 30 minutes to 2 hours of unrelieved pressure. Repositioning every two hours in bed and every hour in a chair is the standard preventive interval.
My mom has a red mark on her tailbone. Is that an emergency?
Press lightly on it with your finger and release. If the redness fades (blanches) and then returns, the skin is intact. If it stays red and doesn’t blanch, that’s Stage 1, a warning sign. Remove pressure from the area, increase repositioning, photograph it, and call your home care nurse if it hasn’t resolved within an hour or two. If it progresses, call BrightStar Care of Phoenix NW/NE and Tempe at 480-897-1166 for a skilled nursing assessment.
Will Medicare pay for wound care at home?
Medicare-certified home health may cover skilled wound care after a qualifying hospital stay, but coverage rules and eligibility are strict. BrightStar Care provides private duty nursing and personal care, which works alongside or after Medicare-certified services end, with no minimum hours and a Registered Nurse overseeing every case.
What should we keep on hand at home for a parent at risk?
A barrier cream for skin exposed to moisture, a foam mattress overlay or pressure-redistributing chair cushion, extra pillows for heel floating, a daily skin-check log, and a phone number for an RN you can call. Don’t buy wound dressings without nursing guidance, choosing the wrong type can dry the wound out or trap bacteria.
How do I find a wound-knowledgeable home care nurse in Phoenix?
Look for an agency with RN oversight on every case, Joint Commission accreditation, and experience with chronic wounds. Ask whether the RN does the first assessment in person, how often the nurse evaluates wound progress, and how the nurse communicates with the patient’s physician. BrightStar Care of Phoenix NW/NE and Tempe meets these standards and is locally owned and operated.
