Users' Perspective on Revised Simple Simulator for Calculating Nutritional Food Stocks in Preparation for Large-scale Disasters.

ABSTRACT

OBJECTIVE: In 2020, Japan's Ministry of Health, Labour and Welfare developed an Excel workbook entitled "Simple Simulator for calculating nutritional food stocks in preparation for large-scale disasters." In September 2021, it was modified as the "Revised Simulator" to plan food stockpiles in normal times and post-disaster meals. This study aimed to further improve the Revised Simulator. METHODS: Eight group interviews were conducted with 12 public health dietitians, 9 disaster management officers, and 2 public health nurses from September to November 2021. They provided nutritional support during previous disasters or prepared for predicted future disasters. Qualitative analysis was conducted on interview transcriptions, then the Revised Simulator was improved based on their feedback. RESULTS: The Revised Simulator was improved to the "Simulator for calculating nutritional food stocks and meals for large-scale disasters" with significant changes such as adding specific tags in the food list to denote long shelf life and elderly-friendly foods, as well as displaying bar graphs to visualize the required and supplied amounts of energy and nutrients. CONCLUSIONS: The Revised Simulator was upgraded for planning and assessing stockpiles and meals in ordinary conditions and emergencies. This study will contribute to enhancing the quality and quantity of food supplies during disasters.
