The Effectiveness of a Caregiver-Based Multicomponent Intervention to Prevent Pressure Ulcers in Home-Cared-For Individuals With Dementia: A Randomised Controlled Trial

Introduction and Aim: Pressure ulcers are preventable complications that are common, particularly in individuals with dementia cared for at home, reducing quality of life and creating significant costs for the healthcare system. The risk of pressure ulcers increases in individuals with dementia due to mobility limitations, communication difficulties, and caregiver dependency; in a home care setting, the knowledge and skill deficiencies of caregivers further exacerbate this risk. The aim of this study is to evaluate the effectiveness of a multi-component training, monitoring, and reminder intervention developed for caregivers of individuals with dementia cared for at home in reducing the risk of pressure ulcers and the development of new pressure ulcers compared to standard care.

This study goes beyond the predominantly institution- and hospital-based approaches in the literature on pressure ulcer prevention, offering a structured, experimental intervention model specific to individuals with dementia cared for at home and their caregivers. This study aims to present a caregiver-based, feasible, and low-cost model for the prevention of pressure ulcers in individuals with dementia receiving home care, and to contribute the findings to scientific publications and home care services. Method: The study was designed as a two-arm, parallel-group randomized controlled experimental design. Patient-caregiver pairs (PCGs) consisting of individuals diagnosed with dementia and their primary caregivers receiving home care were randomized into intervention and control groups. The intervention group (n=60) received a 12-week multi-component program consisting of structured training sessions for caregivers, daily pressure ulcer prevention checklists, weekly coaching sessions, and text message reminders. The control group (n=60) received standard care and general information. The primary outcomes of the project were pressure ulcer risk (Braden Pressure Ulcer Risk Assessment Scale) and the development of new pressure ulcers. Secondary outcomes included caregiver knowledge level, adherence to preventive care practices, and changes in caregiver burden. The obtained data were statistically analyzed.
