The effects of family, society and national policy support on treatment adherence among newly diagnosed tuberculosis patients: a cross-sectional study

Background Non-adherence to tuberculosis (TB) treatment is the most important cause of poor TB outcomes, 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 treatment adherence among newly diagnosed TB patients in Dalian, north-eastern China, and determined the effects of family, society, and 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 to January 2020. Data were collected using a questionnaire that measured medication adherence, family support, social support, and national policy support and so on. Differences between groups were assessed using Chi-square tests 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 who had family members who frequently supervised medication ( OR :0.34, 95% CI :0.16–0.70), family members who often provided spiritual encouragement ( OR :0.13, 95% CI :0.02–0.72), a good doctor-patient relationship ( OR :0.61, 95% CI :0.40–0.93), more TB-related knowledge ( OR :0.49, 95% CI :0.33–0.72) and a high need for TB treatment policy support ( OR :0.38, 95% CI :0.22–0.66) had satisfactory medication adherence. However, patients who had a college degree or higher ( OR :1.69, 95% CI :1.04–2.74) and who suffered adverse drug reactions ( OR :1.45, 95% CI :1.00–2.11) were more likely to have lower adherence. Conclusions Our findings suggested that non-adherence was high in newly diagnosed TB patients. Patients who had family members who frequently supervised medication and provided spiritual encouragement and a good doctor-patient relationship and TB-related knowledge and a high need for policy support contributed to high adherence. It is recommended to strengthen medical staff training and patient and family health education and to increase financial support for improving adherence.
