Diabetic Foot Care and Ulcer Prevention Training for Care Staff

Diabetic foot problems are one of the leading causes of hospital admission and lower-limb amputation among people with diabetes, yet the earliest warning signs are often something as simple as a small blister, a patch of dry skin, or a change in colour that a busy care routine can easily miss. For care staff supporting residents with diabetes, a brief, consistent daily foot check is one of the highest-value, lowest-cost prevention habits available.

Why feet are especially at risk in diabetes

Diabetes can damage both nerves and blood vessels over time, a combination that makes the feet particularly vulnerable. Nerve damage (peripheral neuropathy) can mean a resident doesn't feel pain from a cut, blister, or pressure point the way they normally would, while reduced blood flow (peripheral arterial disease) slows healing once an injury does occur. Together, these two factors mean a minor injury that would heal quickly in most people can progress to a serious wound or infection in someone with diabetes, often without the person noticing until it's already advanced.

Risk stratification: not every resident needs the same level of check

NICE guidance on diabetic foot problems sets out a clear risk stratification system that care settings can align their own checks to. Residents with no additional risk factors beyond simple callus are considered low risk and typically need review as part of their annual diabetes check-up. Those with deformity, neuropathy, or peripheral arterial disease are moderate risk, and guidance recommends specialist assessment within six to eight weeks of referral, with reassessment every three to six months. High-risk residents — those with a previous ulcer or amputation, receiving renal replacement therapy, or with a combination of neuropathy, arterial disease, callus or deformity — need specialist assessment within two to four weeks of referral and reassessment as often as every one to two months, or weekly if there's an immediate concern. Anyone with an active ulcer, infection, chronic limb-threatening ischaemia, gangrene, or suspected acute Charcot arthropathy needs immediate referral to acute services.

What a daily care-staff foot check should cover

Care staff aren't expected to diagnose or stage diabetic foot problems — that's a specialist role — but a short daily visual check during routine personal care can catch problems early enough to make a real difference. This means looking between the toes and across the sole for any break in the skin, blisters, redness, swelling, or discolouration, checking that footwear fits well and isn't rubbing, and noting any change in skin temperature or a new area of hard skin. Any finding, however minor it seems, should be reported and documented rather than "watched for a few days" informally, since the whole point of diabetic foot risk is that visible damage can already represent significant underlying tissue harm.

Footwear and everyday prevention

Well-fitting footwear is one of the simplest and most effective prevention tools available. Shoes that are too tight, too loose, or have seams that rub can create pressure points that a resident with neuropathy may not feel developing. NICE guidance recommends that people at moderate or high risk receive both oral and written information on footwear and basic foot care, and for anyone at higher risk, a pressure-redistribution device to offload heel pressure may be appropriate, particularly after a hospital stay or period of reduced mobility.

Working alongside wider skin and wound care

Diabetic foot checks sit naturally alongside a care setting's broader tissue viability and wound care training, since the underlying principles of early recognition and prompt escalation are the same. Where a resident already has diabetes documented in their care plan, it's worth confirming that foot checks are explicitly built into their daily care routine rather than assumed to be covered by general skin checks, which can miss the specific risk factors that make diabetic feet different.

Frequently asked questions

How often should a low-risk resident's feet be checked by care staff? A brief visual check during routine personal care, ideally daily, is good practice for all residents with diabetes regardless of their specialist risk category, since visual observation costs nothing and catches problems specialist reviews — which happen less frequently — might miss between appointments.

What's the most common early sign of a developing diabetic foot ulcer? A small area of broken skin, a blister, or unexplained redness are the most common early signs, and any of these should be reported the same day rather than monitored informally.

Should residents with diabetes cut their own toenails? Many services refer residents with diabetes to a podiatrist for nail care rather than relying on general care staff, particularly for residents at moderate or high risk, since a minor cutting injury carries disproportionate risk.

A simple, consistent daily habit — look, ask, report — protects residents from one of the most preventable complications of diabetes, and complements wider diabetes care training across the team.
