The Munro Pressure Injury Risk Assessment Scale for Perioperative Patients (Munro Scale) is the first three-phase risk instrument designed specifically for perioperative patients. The purpose of this study was to establish validity and reliability evidence for the Munro Scale. This study also had a goal to reduce the data into more manageable constructs with fewer items. Exploratory and confirmatory factor analyses were used to test the hypothesized model for risk assessment using the Munro Scale to identify latent variables. A retrospective review of charts from 630 risk assessments was analyzed from two community acute care hospital settings. The model explained 95% of the variance in the cumulative final risk level, R = .95, (20, 588) = 501.88, < .001. Six latent variables emerged in the model with a cumulative contribution rate of 56% of the variance. Similar results were obtained in studies with Chinese and Turkish translations of the Munro Scale. The validity and reliability evidence obtained in this study supports the implementation of the Munro Scale for clinical practice in the perioperative setting.
