Figure 1.
State transition diagram of the Markov model. Patients are admitted to the hospital and determined to be one of five risk states for pressure injury using the Braden score. They then transition through different risk categories until they are safely discharged. Patients who develop a pressure injury (ie, Patient-Safety Indicator #3, PSI03) require acute and chronic care, and potentially surgery to safely exit the model, otherwise the pressure injury could be fatal.
