Effects of a 10-week pulmonary rehabilitation program based on the 5A nursing model in patients with interstitial lung disease: a quasi-experimental study.

BACKGROUND

Pulmonary rehabilitation (PR) is essential for treating interstitial lung disease (ILD). The 5A nursing model enhances patients' health-promoting behaviors by improving their self-management skills. The aim of this study is to examine and analyze the effectiveness of the PR program based on the 5A nursing model concerning lung function, dyspnea, anxiety, depression, self-efficacy, quality of life, and PR compliance in patients with ILD.

METHODS

64 hospitalized ILD patients were enrolled in this quasi-experimental study. Patients were randomly assigned to an intervention group (PR program based on the 5A nursing model) and a control group (conventional PR) on a ward-by-ward basis. The allocation was not concealed from the patients. A pre- and post-test design was used. An exercise training diary was utilized to evaluate PR compliance, data was gathered using the mMRC, HADS, PRAISE, and SGRQ, and lung function was assessed by a professional PR-trained nurse. SPSS 26.0 was used to analyze the data. For within/between-groups comparisons, the Wilcoxon signed-rank test, Fisher's exact test, t-test, χ²-test, and Mann-Whitney U-test were employed.

RESULTS

Baseline demographics were generally similar between the two groups (P > 0.05). After 10 weeks of intervention, the PR program based on the 5A nursing model group had more significant improvements in self-efficacy (P = 0.001), anxiety (P = 0.005), and depression (P = 0.018) compared to the control group, but there were no significant differences in dyspnea, lung function, or quality of life (P > 0.05). PR compliance was significantly higher in the intervention group than in the control group (P = 0.028). Further within-group comparisons showed significant improvements in DLCO%pred (P = 0.003), dyspnea (P = 0.001), anxiety (P = 0.006), self-efficacy (P < 0.001), and quality of life (P < 0.001) at post-test in patients in the intervention group compared to pre-test.

CONCLUSION

The PR program based on the 5A nursing model is an effective way to reduce anxiety, depression, and improve self-efficacy and PR compliance in patients with ILD.
