Pressure ulcers (PUs) are among the most common chronic ulcers and complications of hospitalization.


The present study aims to evaluate the prevalence of hospital-acquired PUs and their grades in trauma patients, comparing demographic characteristics, clinical features, and outcomes among patients without and with PUs referred to a trauma center in the North of Iran.


In a retrospective study, 410 patients with trauma referred to a trauma center in the North of Iran were enrolled. Data were collected using a simple random sampling from March 2019 to September 2019.


The prevalence of PU in patients with trauma was 27.6%. Grade III (35.5%) and grade I (3.5%) wounds had the highest and lowest frequency of PU, respectively (P<0.001). The mean age of patients with PU was higher than patients without PU (61.73 vs. 47.71 years, P<0.001). The mean hemoglobin level of patients with PU was lower than patients without PU (9.93 vs. 12.25, P<0.001). PUs were more common in smokers compared to non-smokers (P<0.001), with a history of PU (P<0.001), a history of diabetes mellitus (P<0.001), and a history of hypertension (P<0.001). The mean length of stay in the hospital for patients with PU was higher than for patients without PU (13.02 vs. 5.54 days, P<0.001). 74.3% of people with PUs were completely immobile (P<0.001), and 60% of them had mild brain damage (GCS of 13 to 15). Also, the number of people with severe and moderate brain injury among PUs patients was 15% and 24.7%, respectively (P<0.001). Mobility, brain damage, Hemoglobin rate and smoking status were risk factors for pressure ulcers.


Therefore, it is recommended that health managers and policymakers develop care and treatment plans by considering these risk factors.
