Development of the Japanese version of the Intensive Care Unit Trigger Tool to detect adverse events in critically ill patients

AIM: The Intensive Care Unit Trigger Tool (ICUTT) was developed to detect adverse events (AEs) in intensive care unit (ICU) patients. The purpose of this study was to determine the validity and reliability of the Japanese version of the ICUTT (ICUTT‐J). METHODS: The translation of ICUTT was carried out based on the guideline for translation of instruments. Subsequently, two review teams independently reviewed 50 patients' medical records using the ICUTT‐J, and agreement regarding the presence and number of AEs was evaluated to ensure reliability. RESULTS: The ICUTT‐J was submitted to the authors of the original ICUTT, who confirmed it as being equivalent to the original version. The item‐content validity index and scale‐content validity index were 1.00 and 1.00, respectively. Interrater reliability showed moderate agreement of κ = 0.52 in terms of the presence of AEs and linear weighting of κ = 0.49 (95% confidence interval, 0.28, 0.71) in terms of the number of AEs. CONCLUSION: This study's findings suggest that the ICUTT‐J is valid and moderately reliable for use in ICUs.
