This retrospective study aimed to investigate the prevalence of pressure ulcers (PUs) in older patients with advanced dementia versus older patients without dementia but with other comorbidities, such as diabetes, ischaemic heart disease and chronic renal failure. PUs were thought to be more prevalent and to present a higher risk of mortality in patients with dementia. PUs were assessed on admission using the European Pressure Ulcer Advisory Panel (EPUAP) staging system. Patients were classified as either with or without dementia according to Reisberg's functional assessment staging test (FAST). The prevalence of PUs and the survival rates were analysed and compared in both groups. The combined effect of PUs and dementia on survival was assessed using the Cox proportional hazard model. The median survival rate of patients with PUs and dementia was 63 days, significantly lower than in patients with PUs without dementia 117 days. Both groups had similar other comorbidities. These findings underscore the requirement for geriatricians and health professionals to be more vigilant in examining PUs as dementia progresses.
