Nurses play a key role in health emergency preparedness; however, there is insufficient literature related to nurse disaster readiness in resource-limited and high-risk environments. In GB, which is considered one of the most disaster-prone locations in South Asia, there is no empirically validated scale measuring DNCC. In this paper, a cross-case analysis has been conducted to determine if combinations of Education (EDU), Training (TRN), Organizational Support (ORG) and Structural Barriers (BAR) are necessary and sufficient to generate high or low levels of DNCC in nurses working at public hospitals. Fuzzy-set Qualitative Comparative Analysis (fsQCA) was used for data analysis using direct calibration based on percentile. It has been observed that none of the above-mentioned factors alone are sufficient to generate high DNCC. However, combination of different enabling factors can be responsible for high DNCC, while no organizational support has consistently shown up in configurations leading to low DNCC.
