ObjectiveTo discuss the application of Miller pyramid teaching method in the competency training of new nurses in hemodialysis room and evaluate the effect.MethodsFourteen new nurses in hemodialysis room adopting conventional teaching method from January 2017 to December 2018 were retrospectively selected as the control group; from January to December 2019, another 14 new nurses in hemodialysis room were prospectively selected as the trial group and Miller pyramid teaching method was adopted. After three months of training, the theory and operation of the two groups of new nurses were assessed, and the post competency was assessed by using the Competency Inventory for Registered Nurse, and the teaching satisfaction was assessed by using the self-designed questionnaire on the teaching effect satisfaction of new nurses in hemodialysis room. The data of the two groups were compared.ResultsThe theoretical examination score (91.54±5.89 vs. 83.86±6.45), operational examination score (96.89±3.65 vs. 90.58±5.15), score of Competency Inventory for Registered Nurse (186.66±4.89 vs. 163.76±6.89), and teaching satisfaction (4.56±0.72 vs. 3.56±0.97) in the trial group were all higher than those in the control group, the differences were statistically significant (P<0.05).ConclusionMiller pyramid teaching method is feasible to train the post competency of new nurses in hemodialysis room, which is helpful to improve the theoretical basis, operational skills, post competency, and teaching satisfaction of new nurses in hemodialysis room.
