Methodological Appraisal of the Munro Scale: Psychometric Properties and Diagnostic Accuracy in Adult Surgical Patients: A Methodological Study.
Article in Health science reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Pressure injuries during the perioperative period can adversely affect postoperative outcomes and patient recovery. An essential component of prevention and patient care is systematic risk assessment. The Munro Pressure Ulcer Risk Assessment Scale is a perioperative-specific tool designed to evaluate patients' risk for pressure injuries, enabling early identification of high-risk individuals and facilitating timely preventive interventions by perioperative nurses. Aim: This methodological study aimed to evaluate the validity, reliability, and diagnostic Accuracy of the Munro Pressure Ulcer Risk Assessment Scale (Munro Scale) in adult patients undergoing surgery. Method: This methodological study was conducted on a sample of 200 adult surgical patients from October 2024 to May 2025. Data were collected using the Munro Pressure Injury Risk Assessment Scale alongside a demographic questionnaire. The scale underwent a rigorous process of translation and cultural adaptation following established methodological standards. Psychometric testing encompasses evaluations of content validity, construct validity, and Cronbach's alpha coefficient. Result: Out of 200 surgical patients, 37 (18.5%) developed pressure injuries, mostly classified as Stage I and Stage II. Confirmatory factor analysis (CFA) was conducted using AMOS to evaluate the construct validity of the scale, which included three latent factors: preoperative, intraoperative, and postoperative risk factors. Factor loadings for most items exceeded 0.4, indicating acceptable item relevance. Reliability analysis showed Cronbach's alpha values of 0.84, 0.62, and 0.83 for the preoperative, intraoperative, and postoperative factors, respectively. Composite reliability (CR) values were 0.83, 0.71, and 0.82, confirming acceptable internal consistency. Conclusion: The Munro Scale demonstrated acceptable reliability and validity, confirmatory factor analysis indicating a moderate or limited fit. This scale can be used to assess the risk of pressure injuries in perioperative patients.
