INTERPRETIVE STRUCTURAL MODELING APPLYTO PATIENT SAFETY CULTURE

Interpretive Structural Modeling (ISM) has established a structure of hierarchy element by Warfield in 1973. In the field of the ISM system, to represent in a complex pattern of conceptual structure as a graphically variable relationship, which were simple to be understood than in a textural narratives format. Thus, the ISM is a method of perfecting the relationship between variables, that has identify a particular project problem or issue. The aim of this study is to apply ISM to guide healthcare decision makers to establish and to promote patient safety culture activities in healthcare settings. METHOD This study has identified the interpretation structural model process in Safety Attitudes Questionnaire (SAQ), which has divided into six domains of patient safety culture. Through the correlation of six domains variables, which has set up the adjacent matrix and reachability matrix, finally explanatory structural hierarchy variable model were established. RESULTS 1. Among correlations between of six domain of variables, "teamwork climate” has influenced "safety climate", "job satisfaction", " stress recognition ", " perceptions of management " and " working conditions ". 2. Teamwork climate as the first layer of ISM, perceptions of management as second layer, working conditions as third layer, job satisfaction as fourth layer, stress recognition as fifth layer, and safety climate as sixth layer. CONCLUSIONS Interpretive Structural Model has assisted healthcare decision maker to address and implement as the first priorityin promoting patient safety culture, in contributes to implement of a safe atmosphere to improve patient safety in healthcare settings.
