Abstract
Background: Non-adherence to tuberculosis (TB) treatment is the most important cause of poor TB treatment, and improving support for TB patients is a primary priority for governments, but there has been little research on the effects of family, social and national policy support factors on TB treatment adherence. The current study evaluated the treatment adherence of newly diagnosed TB patients in Dalian, northeast of China, and determined the effects of family, society, national policy support factors on treatment adherence. Methods: A cross-sectional survey was conducted among newly diagnosed TB patients treated at the outpatient department of Dalian Tuberculosis Hospital from September 2019 and January 2020. Data were collected using questionnaire that measured medication adherence, family support, social support, and national policy support and so on. Differences between groups were assessed using the chi-square test and Fisher’s exact tests. Ordinal logistic regression analysis was used to determine the predictors of adherence. Results: A total of 481 newly diagnosed TB patients were recruited, of whom 45.7% had good adherence, and 27.4% and 26.8% had moderate and low adherence, respectively. Patients with family members' frequent supervision of medication (OR:0.34, 95% CI:0.16-0.71), family members' often spiritual encouragement(OR:0.14, 95% CI:0.03-0.80), good doctor-patient relationship (OR:0.58, 95% CI:0.38-0.88), more TB-related knowledge (OR:0.49, 95% CI:0.33-0.72) and high need for TB treatment policy support (OR:0.39, 95% CI:0.22-0.67) performed satisfactory medication adherence. However, patients with a college degree or higher (OR:1.78, 95% CI:1.10-2.88) were more likely to have a lower adherence.Conclusions: Our findings suggested that non-adherence was high in newly diagnosed TB patients. Family members' frequent supervision of medication and spiritual encouragement, good doctor-patient relationship and TB-related knowledge, high need for policy support contributed to high adherence. It is recommended to strengthen the training of medical staff and the health education of patients and their families, increase the financial support for improve adherence.
