The adoption of multi-criteria risk assessment methods, such as probability and impact matrices, in the healthcare sector poses several risks, one of which is subjectivity and bias in decision making. To this end, the aim of this research is to develop a multi-criteria healthcare risk assessment model under fuzzy environment. To achieve this, a three-step research methodology was employed. The study identifies 29 risk factors, with insufficient team cooperation and communication, poor response to health pandemics, and misdiagnosis being the top three risks. The findings of this study might be of value to relevant medical personnel and organisations in effectively managing risks and developing appropriate risk interventions.
