Abstract:Objective：To analyze the application of feedback precision nursing mode in nursing ability of nurses in tumor hospitals. Methods：60 cases of tumor patients in our hospital were selected as the research object，and divided into groups according to different nursing methods（control group and observation group）. The control group was implemented by conventional nursing，and the observation group was implemented by multi-dimensional feedback precision nursing mode. The degree of anxiety and depression，the degree of pain，the incidence of complications，patients’ satisfaction and nurses’ nursing ability were observed. Results：There was no significant difference in anxiety and depression scores between the two groups on the first day of admission（P＞0.05）. After nursing intervention，the scores were compared on the day before discharge. Compared with the first day of admission，the scores of anxiety and depression in the two groups were significantly reduced（P < 0.05）. There was no significant difference in the VAS scores between the two groups on the first day after admission，but there was a difference between the two groups on the day before discharge. The observation group was significantly lower than the control group，with statistical significance（P < 0.05）. In terms of nursing ability score comparison between the two groups，a total of 123 nurses were included in the observation group，with an average of（3.98±0.87）points，while 68 nurses were included in the control group，with an average of（3.43±1.67）points. There was a significant difference between the two groups，with statistical difference（P < 0.05）. Conclusion：The implementation of multi-dimensional feedback precision nursing mode is helpful to relieve patients’ anxiety and depression，reduce their pain degree，improve patients’ satisfaction with the nursing process，and continuously improve the nursing ability of nurses，so it has promotion value.
