With the improvement of social living standards, pregnant women have higher and higher requirements for health and medical personnel. As the main body of medical service personnel, the service objects of midwives are increasing rapidly, while the existing working conditions and abilities of midwives are difficult to meet the growing medical needs of pregnant women. In order to improve the imbalance between supply and demand between limited medical resources and patients’ medical treatment, this paper proposed to use PDCA model to educate and train midwives in order to improve their professional ability and work efficiency. Based on the analysis of the structure and functional principle of PDCA model, according to the working requirements of midwives, PDCA model was used to provide midwives with scientific teaching plan, implementation scheme, inspection requirements, and result evaluation methods. In order to test the effect of the application of this model, a group of hospitalized pregnant women were selected as samples and randomly divided into control group and observation group. Through comparative experiments, the effectiveness of PDCA model in midwife education and training was verified. The experimental results showed that the scores of midwife and patient satisfaction, theory and operation skills in the observation group were higher than those in the control group. Compared with the conventional nursing mode, the use of PDCA cycle mode to educate and train midwives had not only effectively improved the theoretical knowledge and professional skills of nurses, but also significantly improved the nursing and delivery monitoring ability of pregnant women. This study has certain reference and guiding significance for clinical medicine and other related application fields.
