Abstract:

Objective: To analyze the treatment outcomes and influencing factors of elderly rifampicin drug-resistant pulmonary tuberculosis patients. Methods: A retrospective study was conducted, and clinical data of 144 elderly rifampicin drug-resistant pulmonary tuberculosis patients treated at the Anhui Chest Hospital from September 2020 to September 2023 were collected according to inclusion criteria. Treatment outcomes and influencing factors of patients were analyzed. Results: Among the 144 elderly drug-resistant pulmonary tuberculosis patients, 65 cases (45.14%) had favorable treatment outcomes, including 51 cases (35.42%) cured and 14 cases (9.72%) completed treatment; 79 cases (54.86%) had unfavorable treatment outcomes, including 7 cases (4.86%) getting treatment failure, 57 cases (39.58%) lost to follow-up, and 15 (10.42%) deaths, of which 7 were due to tuberculosis. Multifactor logistic regression analysis showed that body mass index (BMI) ≥18.5 (OR=0.131, 95%CI: 0.040-0.429, P<0.001) and long-term supervision and management (OR=0.052, 95%CI: 0.013-0.204, P<0.001) were protective factors for favorable outcomes, while comorbid diabetes (OR=3.266, 95%CI: 1.074-9.936, P=0.037) and gastrointestinal adverse reactions (OR=8.976, 95%CI: 2.582-31.205, P<0.001) were risk factors for unfavorable outcomes. Conclusion: The cure rate of elderly rifampicin drug-resistant pulmonary tuberculosis in Anhui Province was low. Attention should be paid to elderly patients with comorbid diabetes, poor nutritional status, lack of long-term supervised medicine taking and management, and drug adverse reactions. Active control of blood sugar levels, management of adverse reactions, strengthening nutritional support and supervision management are necessary to further improve the cure rate.
