Pressure ulcer (PU) risk assessment practices in adult intensive care unit (ICU) patients remain varied. Purpose: The authors assessed the performance of the Sequential Organ Failure Assessment (SOFA) scale and its subcategories in predicting the development of PUs.

Methods: A retrospective cohort study was conducted of all adult patients admitted to the mixed medical-surgical ICU of a Finnish tertiary referral hospital between January 2010 and December 2012. Data (diagnoses, demographics, clinical information, treatments, and instrument scores) were retrieved from the ICU database. Wilcoxon and chi-squared tests were used to examine patient subgroup (medical or surgical ICU and intensive care or high-dependency care patients), length of ICU stay (LOS), modified Jackson/Cubbin (mJ/C) scores and SOFA subcategory variables, and first-day SOFA scores. PU association was determined by logistical regression. Results: Among the 4899 patients in the study population, the overall PU incidence of acquired PUs was 8.1%. Medical patients had significantly more PUs (145/1281; 11.3%) than surgical patients (212/3468; 6.1%) (P <.0001). In all subgroups, significantly more patients with PUs had higher SOFA scores (mean 8.24) than patients without PUs (mean 6.74) (P=.001). The difference persisted when patients with LOS ≥3 days in the ICU were considered. Among the SOFA subcategories, the Glasgow Coma score, renal and respiratory disorders, and hypotension were significantly (P <.0001) linked to PU development. First-day total SOFA score and its cardiovascular and respiratory subcategory scores were the most important predictors of PUs. Conclusion: The total SOFA score provides an additional tool to assess PU risk in ICUs and should be used together with the Braden or the mJ/C Scale.
