Purpose : The purpose of this study is to develop an integrated nursing curriculum on patient safety for the 4th grade cadets of Korea Armed Forces Nursing Academy. Method : For the Integrated nursing curriculum development, Dick & Carey’s ADDIE model was used. The analysis, design, and development phases were conducted in this study with the exception of implementation and evaluation. In the analysis stage, patient safety guidelines and the education needs of nursing officers in 10 military hospitals were analyzed. Based on the analysis, interviews, and literature review, the authors drafted education topics and contents in the design stage. During the development stage, the validity of the curriculum was checked by experts. Result : Education in four major categories of medication errors, falls prevention, communication, and nursing practice were in high demand. Each category was comprised of its own content items, and finally 39 items in total passed the validity test. The validity score of the 39 items ranged form 0.8 to 1.0. Based on these results, a 30-hour or 4-days program focusing on patient safety was developed integrating adult nursing, fundamental nursing, psychiatric nursing, and nursing management. Conclusion : This study is expected to contribute to improving clinical competency of newly commissioned nursing officers especially for patient safety. Further research needs to determine the effect of the integrated nursing curriculum.
