Systems Thinking Approach to Visualize Problem Structure of Drug Ingestion Accidents by Infants

- Identifying its causal relationships and visualizing overall structure -

抄録

There has been no end to cases of infants opening drug containers meant for adults and accidentally ingesting them, and so it has become a social problem. The authors conducted experiments to evaluate child-resistant (CR) pill containers, which infants find difficult to open, and are also not difficult for ordinary people to use. In this paper, based on the findings of these experiments, we implemented systems thinking and interpreted human activities as an open-ended system, visualized the problem structure of drug ingestion accidents by infants, and were able to demonstrate modifications for preventing accidental ingestion by infants and matters requiring caution.
