Prevalence is the representation of the number of patients within a given facility that have pressure ulcers at a specific point in time (usually 24 hours). Prevalence – using the day’s census, skin assess all patients. P= number of patients with ulcers Number of patients (assessed) in the sample x 100 The census is the number of patients that need to be assessed; however, the actual number assessed may differ. Patients can refuse to participate, be out of the room or not be available during the study time period. Those patients not assessed should be subtracted from the total. Census – patients not assessed = number of patients (assessed) in sample. This applies to prevalence and incidence.
