Interpretative structural modeling method: An analysis of influencing factors analysis on the adverse experiences of cardiac surgery patients in the intensive care units

Objective: To construct an interpretation structure model of adverse experiences of cardiac surgery patients in intensive care unit, so as to provide a reference for optimizing the experience of critical patients step by step.

Methods: Literature review, semi-structured interviews, questionnaires and Delphi method were used to summarize and analyze the influencing factors of intensive care experience in cardiac surgery. The explanatory structural model was used to divide the influencing factors into levels and construct the explanatory structural model of adverse experience of cardiac surgery patients in intensive care.

Results: A hierarchical structure model containing 34 elements and 15 levels was constructed, which were divided into Surface level, middle level and root level.

Conclusion: The intensive care experience of patients in cardiac surgery department is mainly affected by 34 factors. There are direct or indirect correlations between the influencing factors, and different levels have different effects.
