The underlying assumptions in causal models for accidents have an impact on the nature of the conclusions from accident investigations. However, since each model has strengths and weaknesses, it is important to understand how they fit with each other. This study analyzes the relationships between sequential, epidemiological and systemic models. The analysis was based on a hospital maintenance accident. The results indicate that the models are complementary rather than excluding. In particular, the sequential model was shown to be useful for identifying and organizing information of importance for analysis from the perspective of the other models. It was also concluded that the nature of the preventive measures differed substantially between the models. While the sequential and epidemiological models indicated measures relating to the event under investigation, the systemic model indicated changes with a broader impact on the organization.
