Emerging infectious diseases (EIDs) are a considerable threat to health, particularly in long-term care facilities (LTCFs), where residents are especially vulnerable. Nurses’ competency in EID prevention is crucial to minimize the adverse effects of EIDs in LTCFs. This study investigated nurses’ competency and related factors in EID prevention in LTCFs in Tainan, Taiwan. A cross-sectional design was employed, and nurses were recruited to complete an online survey examining the knowl-edge, attitude, and skills required to prevent EIDs in LTCFs. A total of 235 nurses completed the survey. The equivalent score index (SI) for knowledge regarding EID prevention was 68, indicating that the nurses did not have adequate knowledge regarding EID prevention. In contrast, the equivalent SI for the subscale of attitudes toward EID prevention was 78, indicating that the nurses exhibited moderately to highly positive attitudes toward EID prevention. However, they rated themselves as being highly skilled in EID prevention, corresponding to an equivalent SI of 91. Perceived supervi-sors’ approval, marital status, attitudes toward EID prevention, EID prevention skills, knowledge regarding EIDs, and being in charge of infectious disease prevention were significant predictors of the nurses’ competency. LTCF nurses, especially those working in nursing homes, should enhance their knowledge regarding EID prevention. These findings may help improve nurses’ competency in preventing EIDs by encouraging the integration of practice strategies, education, research, and policy recommendations to eliminate EIDs in LTCFs.
