Abstract:
Objective To explore the probability and associated factors of pulmonary fibrosis in 350 cases of elderly pneumonia. Methods Elderly patients who received diagnosis and treatment at Changzhi Medical College Affiliated Peace Hospital from January 2018 to December 2022 were selected, and 350 patients who met the criteria were included in the study. Analyze its clinical data, incidence of pulmonary fibrosis, and analyze the relationship between the two. Results The average age of 350 patients was (63.51 ± 5.74) years old; 219 cases were common type , 72 cases were severe type, and 59 cases were critically ill. At admission, the CT signs were: ground glass in 66 cases (18.86%) , paving stone in 37 cases (10.57%), consolidation in 73 cases (20.86%), nodules in 93 cases (26.57%) , fried egg sign in 20 cases (5.71%) , and mosaic sign in 61 cases (17.43%). At discharge, the lesion signs were as follows: 61 cases (17.43%) had no lesions, 207 cases (59.14%) maintained the original lesion signs, and 82 cases (23.43%) evolved into other signs. 76 cases of pulmonary fibrosis were discharged, with an incidence rate of 21.71%. There were significant differences in the incidence of pulmonary fibrosis among patients with different ages, lesion evolution during treatment, lesion signs at discharge, and clinical stages (all P<0.001). Pulmonary fibrosis is positively correlated with age (P=0.047), lesion signs at discharge (P=0.032), and clinical classification (P=0.010). The incidence of lesions presenting as paving stones (P=0.014) and fibrosis in critically ill patients (P=0.013) at discharge is higher. Age increase (P=0.047) , wide range of lesions at admission (P=0.042), evolution of lesions into other signs at discharge (P=0.016), and clinical classification as severe (P=0.008) or critically ill (P=0.021) are independent risk factors for the development of pulmonary fibrosis in elderly pneumonia patients. Conclusion The incidence of pulmonary fibrosis in elderly patients exceeds 20%. Increasing age, wide range of lesions upon admission, evolution of lesions into other signs upon discharge, and clinical classification as severe or critically ill are independent risk factors for the occurrence of pulmonary fibrosis in elderly pneumonia patients.
