Abstract: Objective To explore the influences of comprehensive nursing intervention on the caregivers of severely burned children. Methods Eighty severely burned children, admitted to our department from November 2016 to November 2017 and conforming to the study criteria, were included in this study. They were divided into comprehensive group and control group according to the random number table, with 40 children in each group. One caregiver for each child was included in the same group. Children and caregivers in control group had routine nursing care while children and caregivers in comprehensive group had comprehensive nursing care on the base of routine nursing care, including comprehensive psychological nursing of children and caregivers, guidance of rehabilitation for caregivers throughout the entire recovery process, individualized propaganda and education for caregivers on account of disease of children, perfecting social support system, sustained attention of children during follow-up. Anxiety self-rating scale and social support rating scale were used to assess the levels of anxiety and social support of caregivers of children in the two groups at the time of admission (before intervention) and the second month after discharge (the third time follow-up, after intervention). On the day of discharge, the nursing service satisfaction questionnaire of our department was used to evaluate the nursing service satisfaction of caregivers of children. Data were processed with chi-square test and independent sample t test. Results (1) Before intervention, the anxiety and social support scores of caregivers of children in control group were respectively (64.5±3.8) and (40.4±2.5) points, similar to (63.5±4.9) and (40.5±2.6) points in comprehensive group (t=0.988, 0.177, P>0.05). After intervention, the anxiety score [(47.2±1.9) points] of caregivers of children in comprehensive group was significantly lower than that of control group [(57.6±4.3) points, t=13.917, P<0.01], and the social support score [(45.3±1.9) points] was significantly higher than (35.9±2.1) points in control group (t=-21.282, P<0.01). After intervention, scores of objective support, subjective support, and social support utilization in the social support evaluation rating of caregivers of children in comprehensive group were significantly higher than those in control group (t=12.678, -11.079, -10.031, P<0.01). (2) At the time of discharge, scores of clinical care, propaganda and education content and form in the nursing service satisfaction questionnaire of caregivers of children in comprehensive group were significantly higher than those of control group (t=-14.757, -15.627, -33.221, P<0.01). Conclusions Comprehensive nursing intervention method can effectively reduce the anxiety of the caregivers of severely burned children, help them to make better use of social support system, and improve the satisfaction of caregivers in nursing services.
