Background: Nursing informatics in educational activities can serve as a strategy to bridge the gap between clinical practice and nursing education programs. Objectives: This study aimed to assess the informatics competency of nursing faculty members and its application in educating nursing students at Abadan Nursing Faculty. Methods: This descriptive-analytical research was conducted in 2023 at Abadan Nursing Faculty. The sample consisted of 73 faculty members from the nursing, operating room, and anesthesia departments, who were included in the study through census sampling. Data collection was performed using the standardized Nursing Informatics Competency Assessment Tool (NICAT) and an electronic teaching aids checklist. Data were analyzed using SPSS version 18, with independent t-tests, one-way analysis of variance (ANOVA), and Pearson’s correlation at a significance level of P < 0.05. Results: The mean score of faculty members’ nursing informatics competency at the Nursing Faculty was 110 out of a maximum of 150, placing it within the proficient range. The highest score for nursing informatics competency was related to the informatics literacy dimension (47.65), while the lowest was related to the information management skills dimension (19.54). Information management skills (r = 0.881, P < 0.001), computer literacy (r = 0.871, P < 0.001), and informatics literacy (r = 0.976, P < 0.001) were significantly correlated with nursing informatics competency. Faculty members reported the highest use of multimedia content development (mean score = 4.19) and the lowest use of robotic surgery (mean score = 1.71). Conclusions: Faculty members’ informatics competency was reported to be at a proficient level. However, due to advancements in technology and transformations in nursing care, it seems necessary to improve nursing faculty members’ abilities in all aspects, particularly in the information management skills dimension. It is recommended to hold faculty development programs regarding the integration of technology into the curriculum to elevate the quality of education.
