To study the effect of comprehensive intervention strategies on pulmonary function and life status of elderly patients with stable chronic obstructive pulmonary disease (COPD).

A total of 120 elderly patients with stable COPD who were treated at our hospital from December 2018 to December 2019 were divided into either an observation group or a control group according to the patients' willingness, with 60 cases in each group. Patients in both groups were given basic treatments such as relieving cough, phlegm, tracheal spasm, and asthma, and patients in the observation group were additionally given comprehensive intervention strategies. The patients were followed at 1, 3, and 6 months after intervention to observe the changes in nutritional status, the ability of daily life, the weakness status, and the pulmonary function.

The MNA scores of patients in the observation group at 1, 3, and 6 months after intervention were 21.81±1.28, 23.39±1.03, and 24.32±0.91, respectively, which were significantly higher than that before intervention (20.48±0.83) (P＜0.05) and those in the control group after intervention (P＜0.05).The ADL scores of patients in the observation group at 1, 3, and 6 months after intervention were 73.20±5.60, 85.00±7.07, and 89.58±6.20, respectively, which were significantly higher than that before intervention (68.50±5.77) (P＜0.05) and those in the control group after intervention (P＜0.05). The MFS scores of patients in the observation group at 1, 3, and 6 months after intervention were 32.75±0.96, 26.33±8.78, and 18.17±9.61, respectively, which were significantly lower than that before intervention (38.67±7.97) (P＜0.05) and those in the control group after intervention (P＜0.05). After the intervention, the FVC value increased slightly in both groups, and the difference between the two groups was not statistically significant (P＞0.05). The FEV₁ in the observation group improved from (2.46±0.45) L before intervention to (2.84±0.26) L after management , and FEV₁% improved from (57.68±12.73)% before intervention to (77.05±5.92)% after management, the differences were statistically significant (P＜0.05).

Comprehensive intervention strategies can significantly improve the pulmonary function, the ability of daily living, and the frailty and nutritional status of patients with stable COPD, thus improving their life status.
