Figure 1 is an analytic framework that depicts the events that individuals experience while undergoing risk assessment and implementation of preventive interventions for pressure ulcers. The figure illustrates how an asymptomatic patient population undergoes risk assessment, and how patients found to be at high risk are enrolled in preventive intervention designed to reduce outcomes of pressure ulcer incidence and severity. The patient population of interest is adults in various settings without pressure ulcers. Risk assessment stratifies these patients into high and low risk. High-risk patients receive preventive interventions. The outcomes of interest are pressure ulcer incidence and severity. The figure also depicts the possibility of harms or adverse events occurring as a result of preventive interventions.
