Simplified Acute Physiology Score 2 and Pressure Ulcer Prediction in ICU.

Critically ill patients admitted in intensive care units are at high risk of developing pressure ulcer (also known as pressure injury). In Bordeaux teaching hospital, a prevalence survey identified the department of anaesthesia and Intensive Care Unit with the highest rate for pressure ulcer (up to 29% of patients). Yet, developing a PU will increase patient's pain, health expenses, and the risks for further complications such as infection, prolonged hospitalization and a higher mortality rate. Therefore, this study aims at improving pressure ulcer prediction by using the Simplified Acute Physiology Score 2 (SAPS 2) as the latter estimates the severity of a patient condition while factoring in several causative factors for pressure ulcer among ICU patients. This could then lead to a better use and allocation of human and material resources and improve patients' care.

Inclusion Criteria: * Adults ≥ 18 years of age; * Patients admitted to intensive care unit; * Patients without any preexisting pressure ulcer on admission; * Capacity to give informed consent. Exclusion Criteria: * Length of stay less than 24 hours; * Decline to participate in the study; * Admission criteria being post-surgery monitoring and/or admission for drug intoxication * Patients admitted to ICU with a pre-existent sacral pressure ulcer (any stage).
