Validation of an Instrument to Measure the Results of Quality Assurance in the Operating Room

Background and Objectives: This study aims to validate an instrument designed to measure care quality in the operating room. Methods: We conducted a transversal exploratory descriptive study with the objective of analyzing the psychometric properties of the scale. The 13 items included in the scale result from 2 previously conducted studies, a literature review study and a Delphi study. The instrument was administered to health professionals with at least 2 years of experience in the operating room in 71 Portuguese hospitals. Results: The sample consisted of 1019 professionals who worked in an operating room; among them were nurses and doctors. The results show that the scale is a reliable and valid instrument composed of 3 dimensions: assessment of the quality of care; evaluation of processes; and control systems. Conclusion: The final version of the scale meets the validity requirements, revealing high potential to be used in research and clinical practice. The use of this scale will allow evaluation and comparison of the results among the different operating rooms.
