Description
Summary:Pressure ulcers (PUs) are one of the leading potentially preventable adverse events in the hospital. Critically ill patients are at risk for the development of PUs. The primary aim of the study was to investigate the relation of PUs and obesity in critically ill ICU patients. A single center prospective cohort study was conducted on adult patients with obesity (defined as a body mass index BMI ≥ 30 kg/m2) and patients without obesity (BMI 18−25 kg/m2) admitted to the intensive care unit between May 2013 and July 2017 with an ICU length of stay of at least 3 days without pre-existing PUs at admission. 851 of 1205 patients (70.6%) had a normal BMI and 354 (29.4%) had a BMI ≥ 30 kg/m2 and were considered obese. Overall, 157 patients (13.0%) developed PUs; 112/851 (13.2%) of patients without obesity and 45/354 (12.7%) of patients with obesity (p = 0.907). There was no difference in the severity (p = 0.609) and PU location (p = 0.261). Mean days to PU development was 11.1; 11.7 days for patients without obesity and 9.5 days for patients with obesity (p = 0.270). Mean days to PU recovery was 13.2, which was 14.1 days for patients without obesity and 10.8 days for patients with obesity (p = 0.215). A multivariate logistic regression model showed no significant correlation between the occurrence of PUs in the ICU and obesity (OR 0.875 with 95% CI 0.528–1.448, p = 0.594). Subgroup analysis showed that patients with morbid obesity (BMI ≥ 40 kg/m2) developed PUs earlier during ICU admission when compared to patients without obesity (p = 0.004). Our study demonstrates that obesity is not an independent risk factor for the development of PUs in the ICU. However, patients with morbid obesity might develop PUs earlier compared to patients without obesity.
