Identifying Critical Success Factors for Sustainable Healthcare 4.0: A Novel Fuzzy QFD Approach

Healthcare 4.0 brings Industry 4.0 technologies into medical services, opening new paths to sustainability. This study identifies and ranks the critical success factors needed for a sustainable transition. Drawing on the literature, we treat these factors as customer expectations and evaluate them using a hybrid method that combines Quality Function Deployment with the Interval Valued Pythagorean Fuzzy Analytic Hierarchy Process. The analysis shows that strong data security is the top customer priority, while structured support to address resistance to digital transformation is the leading technical requirement. These findings give healthcare organizations a clear framework for adopting Healthcare 4.0 practices that conserve resources and satisfy evolving stakeholder demands.
