ObjectiveTo investigate the effects of problem-intervention-outcome (P-I-O) teaching method on the normalization training of new nurses. MethodsA total of 101 new nurses from 2011 to 2013 were included in this research. Forty-two new nurses who were invited from August 2011 to July 2012 were distributed into group A, and 59 new nurses who were invited from August 2012 to July 2013 were distributed into group B. Both groups accepted normalization training. Group B accepted P-I-O teaching at the same time. We assessed the differences in operating, theory, attendance, the rates of harmful events and the degree of satisfaction between the two groups. ResultsTheory and operating between the two groups had significant differences (t=3.44, 2.86; P<0.05). Attendance, rates of harmful events and the degree of satisfaction all had significant differences between the two groups (t=2.94, χ2=8.45, Z=-2.05; P<0.05). ConclusionThe application of P-I-O teaching method in the normalization training of new nurses can stimulate their study interest and enthusiasm, transit their role faster, as well as reduce the rates of clinical harmful events and elevate the quality of care. Thus, it is worthy of being popularized in clinical nursing care.
