Pressure ulcer care is the systematic investigation and application of methods aimed at preventing, assessing, and managing pressure ulcers. This academic concept investigates the multifactorial etiology, risk factors, and pathophysiological mechanisms underlying pressure injury development, encompassing the development and evaluation of evidence-based strategies for risk assessment, prevention protocols, wound classification, and therapeutic interventions. As a critical area within healthcare research, it seeks to optimize patient outcomes, mitigate complications, and inform clinical practice guidelines for vulnerable populations.
