Objective To investigate the effect of nursing intervention based on Kano model on surgical outcomes and negative emotions in patients with diabetic retinopathy(DR).Methods A to-tal of 262 DR patients who underwent vitrectomy were randomly divided into control group(n=131)and observation group(n=131)using the random number table method.The control group received routine nursing intervention,while the observation group received nursing intervention based on the Kano model.The surgical outcomes[visual acuity level and improvement in visual function],nursing needs[Perioperative Nursing Needs Questionnaire for DR Surgical Patients],negative emotions[Self-Rat-ing Anxiety Scale(SAS)and Self-Rating Depression Scale(SDS)],and quality of life[Chinese Version of Low Vision Quality of Life Scale(CLVQOL)]were compared between the two groups.The incidence of complications during the intervention period was also recorded in both groups.Results After interven-tion,the visual acuity levels in both groups increased compared to those before intervention,and the rates of low vision decreased(P＜0.001).The visual acuity level in the observation group was high-er,and the rate of low vision was lower than that in the control group,with statistically significant differences(P＜0.001).After intervention,the scores for peripheral visual field,sensory adaptation,and limitations in daily activities decreased in both groups compared to those before intervention,and the scores in the observation group were lower than those in the control group(P＜0.05).After intervention,the SAS and SDS scores in both groups decreased compared to those before interven-tion,and the scores in the observation group were lower than those in the control group(P＜0.001).After intervention,the CLVQOL scores in both groups increased compared to those before the intervention,and the score in the observation group was higher than that in the control group(P＜0.001).The incidence of complications in the control group was higher than that in the obser-vation group(12.22％versus 4.58％,P＜0.05).Conclusion Nursing intervention based on the Kano model can improve visual acuity level,visual function,and negative emotions,enhance the quality of life,and further reduce the incidence of complications in DR patients undergoing vitrectomy.

Objective To explore the application of knowledge-attitude-practice theory in low back pain prevention of operating room nurses. Methods From May 2014 to May 2015, 189 operating room nurses in 6 third-level grade-A hospitals were surveyed by self-designed questionnaire about their knowledge, attitude and practice on low back pain. Intervention measures were made according to investigation results. The 189 nurses were randomly divided into control group ( n=95) and intervention group ( n=94) . Nurses in the control group were not intervened, while nurses in the intervention group were intervened by“knowledge-attitude-practice” on low back pain. After the 8-week intervention, nurses in the two groups were surveyed again. Visual analog scale ( VAS) of nurses from the two groups about low back pain was compared before the intervention, after the 4 weeks and 8-week intervention.Results Before the intervention, scores of knowledge, attitude and practice of nurses in the two groups were both lower than 48 points. Knowledge-attitude-practice scores and VAS scores were statistically meaningless ( P>0.05) . After the 8-week intervention, scores of low back pain prevention knowledge (69.5±16.3), attitude (64.8±15.3) and practice (66.3±16.2) of nurses in the intervention group were all higher than that in the control group (t=-6.720, -4.759, -5.176; P<0.05). 4 weeks and 8 weeks after the intervention, VAS scores of low back pain of nurses in the intervention group were (3.7±0.8) and (2.7±0.8), both lower than that in the control group (t=3.433, 4.217;P<0.05).Conclusions High incidence of low back pain in operating room nurses is related to their low protection knowledge, attitude and practice. Intervention of knowledge-attitude-practice can effectively promote relief and prevention of low back pain of nurses.
