Factors associated with treatment adherence among pulmonary tuberculosis patients in New Delhi.

Background: TB is treated with a six-month course of four antimicrobial drugs, and nearly all cases of TB can be cured if the medications are given and taken correctly. Due to its prolong treatment plans, there can be reasons associated with non-adherence to treatment by TB patients. Hence, the present study aimed to explore the factors associated with medication adherence among TB patients.

Method: A cross-sectional descriptive survey was conducted among adult pulmonary tuberculosis patients enrolled under RNTCP (now NTEP) in New Delhi among 27 functional RNTCP districts. Around 200 TB patients who are enrolled in the Nikshay App and are also on treatment were considered. A structured questionnaire was prepared for the interview guide. Analysis was done using bivariate analysis, chi-square tests, and Fisher's exact tests.

Results: Among the total participants, 173 (86.5%) were adherent and the remaining 27 (13.5%) participants were non-adherent. The majority of the participants (91%) said they were able to follow the routine to the DOTS center, and 9% said they find it difficult to report to the DOTS center as per their schedule. Only 12.35% of non-adherent participants were seen among those who get regular reminders from their families to take medicines, as compared to 18.42% among those who did not get regular reminders from their families. More than one-fourth of the participants (25.9%) who report not getting necessary motivation from healthcare providers were non-adherent. Motivation by healthcare workers to follow drug schedules was found statistically significant to treatment compliance with a P-value of 0.0422.

Conclusion: TB is a curable disease; this belief has turned out to be a motivational factor for patients suffering from this disease. Studies have shown that faith in the efficacy of treatment helps adherence to TB treatment while other studies describe how patient adherence was adversely affected by the belief that TB is incurable or the treatment is inefficient or that alternative treatment such as traditional medicine is better.
