Abstract:Objective To set up the pre-job intravenous therapy courses for nursing interns using the Delphi method based on the competency-based theory. Methods Through literature reading and preliminary research， Delphi method was used to conduct two rounds of correspondence with 24 relevant experts on the content and importance of the pre-job intravenous therapy characteristic courses for nursing interns， and it was planned to build a characteristic intravenous therapy courses suitable for nursing interns before taking up clinical posts. Results Both positive coefficients of expert correspondence were 100%， and the coordination coefficient of expert opinions was 0.651 and 0.682， respectively. And the authority coefficient was 0.82. Eventually， ten characteristic courses of pre-job intravenous therapy for nursing interns were determined. 〖JP2〗Through the pre-class and post-class survey of the students who were taught， it was found that the students fear scores of clinical works decreased［（2.55 ±0.10) vs (2.94±0.09), P＜0.01］ significantly， and their confidence scores of their own intravenous infusion skills ［(3.70±0.14) vs (3.31±0.06), P＜0.01］ and competence for clinical intravenous infusion work ［（3.94±0.15) vs (3.43±0.06), P＜0.01］ increased significantly. Conclusion Based on the competency-based theory， the application of Delphi method in setting up the characteristic courses of intravenous therapy can effectively expand the knowledge of nursing students before entering the clinical practice and improve their self-confidence.
