The purpose of this study was to find the change in knowledge regarding disaster management among nurses after educational intervention.

One group pretest and post test design was adopted for the study. The study was carried out in B.P. Koirala Institute of Health Sciences, Nepal. Forty Nurses were selected from emergency, orthopedics, medicine, and surgical ward by using non-probability convenience sampling technique. A self-administered semi-structured questionnaire was used to collect the data. Data was collected before and after the educational intervention. The collected data were analyzed using descriptive statistics (frequency, percentage, mean, standard deviation) and inferential statistics (Chi-square and Z test) were used to identify the difference in knowledge between pre-test and post-test, at 0.05 level of significance.

Study findings revealed that in the pre-test, grand mean of the means of the nurses' knowledge on different aspects of disaster management as a whole was 2.39 with the standard deviation of 0.87. Similarly the grand mean of means of knowledge on different aspects of disaster management was 3.2 with the standard deviation of 0.47 in the post-test. The difference between pre-test and post-test in respondents' knowledge in different aspects of disaster management as a whole was calculated by using “Z” test (p < 0.05) The result showed that the educational intervention was effective in bringing changes in knowledge in all aspects of disaster management.

Study findings revealed that there was significant increase in knowledge in the post-test after the educational intervention. Therefore, it can be concluded that education plays an important role in increasing awareness. It is recommended that awareness programs on disaster management should be carried out periodically as in-service education.
