Pressure ulcer/injury remains a significant health problem in the community, requiring comprehensive care. Nurses are involved in the management and prevention of pressure injury. However, to date, studies focusing on applying nursing theory to pressure ulcer care have been limited. In the present study, the three dimensions of Lydia Hall's 1964 theory—core, care and cure—are extensively discussed and linked with the practice of pressure injury management. It is hoped that this review will help community nurses understand the application of this nursing theory to the prevention and management of pressure injury.
