Prevalence, location, grade of pressure ulcers and association with specific patient characteristics in adult spinal cord injury patients during the hospital stay: a prospective cohort study.

Study design:This was a prospective cohort study.Objectives:The objective was to describe the incidence, prevalence, characteristics of pressure ulcers (PUs) and the association with specific patient characteristics in a consecutive sample of in-patients with a spinal cord injury (SCI).Setting:An acute care and rehabilitation clinic specialized in SCIs in Switzerland.Methods:The presence and characteristics of PUs for all adult patients with a SCI admitted to the clinic from 1 September 2009 to 28 February 2010 were recorded on a daily basis during their complete hospitalization. Risk factors were analyzed in univariate and multivariate logistic regression models.Results:A total of 185 patients were included in the study and observed for the entirety of their hospitalization. The prevalence of at least one PU was 49.2% in all patients, compared with 25.4% in the group of patients admitted without PUs. The incidence was 2.2 per person and year. In 91 patients, a total of 219 PUs were observed. PUs were most frequently located on the foot (36.1%), and the coccyx/sacrum (15.1%). The risk for occurrence of a PU increased with age (odds ratio (OR)=1.04) and post SCI (OR=1.03). In the multivariate analyses, the risk for PUs was lower for patients with the American Spinal Injury Association (ASIA) Impairment Scale (AIS) of C or D (OR_C=0.25, OR_D=0.28) compared with patients with an AIS of A.Conclusion:Using a daily documentation system, PUs were detected as a frequent complication of SCIs. Completeness of injury, age and time since injury were significant risk factors for PUs. The foot was a region at high risk for PUs. [ABSTRACT FROM AUTHOR]
