Objective To explore the principles of learning curve on redesign of orthopedic admission nursing procedure in order to provide reference to promote the overall nursing procedure .Methods A total of 250 cases after redesign of orthopedic admission nursing procedure were analyzed .These cases covered the stage from the beginning to the matured stage .Every 50 cases were taken as a group and a phase of learning curve . The admission time and satisfaction score were compared among the five different phases ( groups ) .The linear regression technique was employed to research the learning curve and the effect of admission time on the patients 'satisfaction.Results The mean admission time in each group was (27.47 ±3.64) min in Group A, (23.86 ± 1.95)min in Group B, (21.84 ±2.09)min in Group C, (21.74 ±1.83)min in Group D, and (21.85 ±1.79) min in Group E, respectively.The scores of patients'satisfaction in each group were (95.32 ±1.57)min in Group A, (97.44 ±0.95)min in Group B, (98.78 ±0.51)min in Group C, (99.00 ±0.35)min in Group D, and (98.96 ±0.35) min in Group E, respectively.The differences were significant (P <0.01).Further analysis showed that , compared Group A with the other groups , the differences in the admission time and patients'satisfaction were significantly different (P<0.01).The differences of admission time and patients'satisfaction among Group C, Group D and Group E had no difference (P>0.05).The learning curve (R2 =0.747,F=289.389,P<0.05) of redesign of orthopedic admission nursing procedure showed that there was linear regression relationship between the admission time (R2 =0.669,F=500.532,P<0.05) and patients'satisfaction.Conclusions The redesign of orthopedic admission nursing procedure is characterized by the learning curve , which the first 100 cases are in the learning stage and after 100 cases is the matured stage .The redesign of orthopedic admission nursing procedure can significantly decrease the admission time and is benefit to establish “the good first impression” and the improvement of the patients'satisfaction.
