This paper aims to evaluate the level of maturity of preparedness as a concept in the nursingdiscipline. We analysed articles published between 2015 and 2024. Morse and colleagues developedepistemological, logical, pragmatic, and linguistic principles to evaluate the maturity level ofpreparedness. The results imply that the concept of preparedness in disaster nursing is stilldeveloping, with varying definitions and measurement methods. How preparedness is defined canassist adequate nurses in preparing to respond to any disastrous situation, which mitigates the negativeconsequences of the event. This results in saving victims, improving nurses’ fulfilment, and enforcinghealth facilities' roles in serving populations. Preparedness is an important concept for nursing indisaster; further studies and analysis are needed to develop and clarify preparedness concepts.
