The knowledge and attitudes regarding pressure ulcer prevention among Healthcare Support Workers in the UK: a cross-sectional study


Background: Pressure Ulcer has a significant psychological, economic and social impact on individuals and family. It also represents a significant cost burden for health and social care systems. Nurses and healthcare professionals are primarily accountable for preventing pressure ulcers. Healthcare support workers are an expanding group of key workers in the UK, with healthcare assistants alone constituting approximately one third of the caring workforce in UK hospitals.

Objective: To examine healthcare support workers knowledge and attitudes regarding to pressure ulcer prevention.

Methods: A cross-sectional study using validated Knowledge Assessment Tool and Attitudes toward Pressure Ulcer Prevention Tool was conducted from December 2020 to June 2021 among UK healthcare support workers across different settings.

Results: A total of 226 participants completed the questionnaires partially (n=62) or fully (n= 164). Lower mean knowledge score of 42%, but positive attitude score of 75.4% were reported among healthcare support workers. Participants working in acute hospital wards (46%) and nursing home (47%) scored higher in knowledge of pressure ulcer prevention than those in other settings, participants working in primary care scored lowest 8.95 (34.4%) (p<0.05, ANOVA). The weakest areas of knowledge include the aetiology of ulcers, risk assessment of pressure ulcer and addressing pressure-reducing interventions for patients at risk of developing pressure ulcer. Participants who had positive attitude towards pressure ulcer prevention significantly correlated to higher total score of knowledge in pressure ulcer prevention (p<0.005, Pearson correlation).

Conclusion: While positive attitude towards pressure ulcer prevention exist among healthcare support workers, this is overshadowed by significant knowledge deficits. Findings highlight the importance of continuing structured pressure ulcer prevention education for support workers across both acute and community settings, particular primary care and acute hospital outpatients departments. Future a national survey and interventional study is needed to examine healthcare support workers’ pressure ulcer knowledge and to inform a national continuous education strategy.
