An audit was performed at an NHS trust over a 6-month period to examine the mortality rates of patients reported to have SCALE grade 2, 3 or 4 pressure ulcers in acute care. It was found that 44% of the patients reported to have such pressure ulcers passed away within 8 weeks.
Investigation into the likely factors behind these findings suggests that a large proportion of pressure ulcer incidence may be related to the physiological comorbidities which occur at the end of life.
