Abstract:

Objective To explore the effect of nursing interventions with peer support on respiratory function and life quality of patients with chronic obstructive pulmonary disease (COPD). Methods A total of 79 COPD patients, who visited No. 7 Department of Internal Medicine of Wangkai Infectious Disease Hospital from January to October 2018, were recruited in this study. Among them, 39 patients, who received routine nursing intervention from January to May 2018, were in the control group; while 40 patients, who received nursing intervention with on peer support from June to October 2018, were in the observation group. In the control group, the routine nursing interventions were provided to the patients while the nursing interventions with peer support based on routine nur-sing were given to the patients in the observation group. The difference of respiratory function, life quality and 6 min walking distance (6-MWD) of the patients in the two groups were compared after three-month interventions.Results After the interventions, FEV₁ of the patients in the observation group was (1.9±0.4)L while that was (1.5±0.3)L in the control group. There was significant difference between two groups (t=-4.16, P=0.000). FEV₁% of the patients in the observation group was (65.2±6.6)% while that was (56.5±8.7)% in the control group. There was significant difference between two groups (t=-5.20, P=0.000). The value of FEV₁/FVC of the patients in the observation group was 76.2±6.3 while that was 68.5±5.3 in the control group. There was significant difference between two groups (t=-5.88, P=0.000). After interventions, the QOL scores of the patients in the two groups were compared and the results showed that the scores of physiological domain, psychological domain, independent domain, social relationship domain, environmental domain and spiritual/religious domain in the patients of observation group were 83.8±4.0, 81.3±2.1, 82.3±2.5, 80.5±2.5, 87.3±2.4 and 84.5±2.6 respectively; while those were 70.8±4.2, 57.9±1.5, 70.5±2.3, 69.9±2.3, 72.9±2.4 and 70.5±2.8 respectively in the patients of control group. There were significant difference in all six domains between the two groups (t=2.58, 2.69, 2.71, 1.79, 2.83, 2.76 respectively; P=0.023, 0.021, 0.018, 0.029, 0.014, 0.016 respectively). The 6-MWD test result of the patients in the observation group was (409.1±83.0)m while this value was (363.9±81.8)m in the patients of control group. There was significant difference between two groups (t=-2.45, P=0.016).Conclusion Nursing interventions with peer support can effectively improve the respiratory function and life quality of COPD patients.
