Pressure ulcers are wounds that typically occur on bony prominences, primarily due to external factors such as pressure, friction, and shear, as well as internal factors related to the patient. These ulcers can lead to serious health issues and have a high incidence rate, negatively impacting patients' quality of life, increasing hospitalization duration, and adding to healthcare costs. Prevention of pressure ulcers is considered an important indicator of care quality worldwide and in our country. International guidelines emphasize key points for preventing pressure ulcers, including risk assessment, skin assessment and care, nutrition, repositioning, support surface use, documentation, and education.

A pressure ulcer is defined as "localized skin and/or subcutaneous tissue damage caused by pressure alone or in combination with pressure or tearing, usually occurring on bony prominences". Mostly, it develops as a result of prolonged compression of soft tissue between the bony prominence and the outer surface. External factors such as a large force applied for a short period of time or less force applied for a long period of time, friction, tearing, and stretching to which the skin is exposed disrupt the blood flow to the area, prevent oxygen and nutrient transport to the tissues and cause pressure sores. An overly moist environment caused by sweating, urinary or fecal incontinence or excessive wound drainage increases the harmful effects of pressure, friction and shearing. It also causes maceration of the surrounding skin, which combines these factors. Friction and moisture have their greatest effect in areas of high pressure. If moisture is present, the effects of friction increase up to five times. In addition, intrinsic risk factors associated with the development of pressure sores include old age (70 years and older), immobility/impaired mobility, dehydration, impaired sensory perception and tissue perfusion, malnutrition, anemia, low albumin levels, hypothermia, hypotensive episodes, diabetes and peripheral vascular disease, medications that cause vasoconstriction, current smoking history, dry skin, low Body Mass Index, altered mental status (e.g. confusion), urinary and fecal incontinence, physical limitations, malignancy, history of pressure ulcers. Urinary and fecal incontinence, physical limitations, malignancy, history of pressure ulcers. Pressure ulcers, a pathology with high morbidity and mortality, cause a significant increase in caregiver burden and care costs. Treatment of pressure sores ranks third in terms of cost after malignancies and cardiovascular diseases. In a study conducted in nursing homes in the UK, pressure ulcer treatment costs 1.4-2.1 billion pounds per patient. In Turkey, the annual cost is estimated to be $1 billion 425 million. The European Pressure Ulcer Advisory Panel (EPUAP) recommends that identifying pressure ulcers at Stage 1 and preventing complications and deepening by taking effective measures is the most effective way to reduce costs.

Today, guidelines have been developed in the light of evidence-based practices to prevent pressure ulcers. The main prevention interventions included in these guidelines are assessment of pressure ulcer risk, skin assessment and care, assessment and support of nutritional status, changing position, use of support surfaces, education of healthcare professionals, patients and their relatives, and record keeping. The simplest and easiest way to prevent the development of pressure sores is to take prevention measures. The basic approach in the prevention of pressure sores is to evaluate the possible risks to prevent the development of the wound before it occurs, early identification of the risk group and early implementation of prevention initiatives. EPUAP and NPUAP recommend that all bedridden patients with limited mobility should be considered in the risk group. In the light of all this information, in this study, it was aimed to provide training to the caregivers of bedridden patients to prevent pressure ulcers at home in line with the recommendation of the guidelines as one of the effective interventions in the prevention of pressure sores and to examine the effect of this training on pressure ulcer formation.
