Objective To explore the application value of the collaborative nurse-family supervision model in elderly patients with pulmonary tuberculosis.Methods Eighty-six cases of elderly patients with pulmonary tuberculosis admitted to a hospital in Henan province from September 2018 to October 2020 were selected and divided into an observation group and a control group using the random number table method

with 43 cases in each group.Patients in the control group were given conventional care

and patients in the observation group received the collaborative nurse-family supervision model on the basis of the control group.Patients in the two groups were compared in terms of chest X-ray lesion absorption

readmission rate

compliance behavior

self-efficacy

and pulmonary function [forced expiratory volume in the first second（FEV1）

FEV1/forced vital capacity（FVC）] before and after the intervention.Results The scores for the rational diet

standardized medication and smoking and alcohol cessation dimensions in the post-intervention compliance scale were higher in the 2 groups than before the intervention

and were higher in the observation group than in the control group

with statistically significant differences（P<0.05）.The scores of GSES were higher in the 2 groups than before the intervention

and were higher in the observation group than in the control group

with statistically significant differences（t=7.481

P<0.001）.The lung lesion absorption rate of patients in the observation group was 90.70% after the intervention

which was higher than that of the control group（67.44%）

and the difference was statistically significant（χ~2=7.027

P=0.008）.FEV1 and FEV1/FVC levels of patients in the 2 groups were higher than those before the intervention

and the observation group was higher than the control group

and the differences were statistically significant（P <0.05）.The 1-year follow-up readmission rate of patients in the observation group was 9.30%（4/43）

which was lower than that of the control group（25.58%

11/43）

and the difference was statistically significant（χ~2=3.957

P=0.047）.Conclusion The collaborative nurse-family supervision model is beneficial for improving self-efficacy

improving patient compliance behavior and pulmonary function

and reducing readmission rates in elderly patients with pulmonary tuberculosis.
