Patients' experiences and perceptions on associates of TB treatment adherence: a qualitative study on DOTS service in public health centers in Addis Ababa, Ethiopia.

TB treatment non-adherence was not found to be a major challenge among the study participants. Perceived risk and wellness were implied to be responsible factors for adherence. Albeit the fact that few informants encountered unethical behaviors by some health professionals, interviewed patients generally had positive evaluation of the patient-provider relationship and the DOTS service obtained. There is a need to train and monitor DOTS service providers and ensure the provision of DOTS service by the same provider throughout the treatment period of a given patient.
