Evaluation of directly observed tuberculosis treatment strategy in Ethiopia : patient centeredness and satisfaction

Abstract

Purpose: The purpose of the study was to evaluate the effectiveness of the tuberculosis directly observed treatment, short-course (DOTS) strategy with respect to patient centeredness and satisfaction, and propose a model in support of the DOTS strategy in Addis Ababa, Ethiopia. Method: The study was conducted in Addis Ababa, Ethiopia using a mixed-method approach. An interviewer-administered questionnaire was used to collect quantitative data from 601 randomly selected TB patients who were on TB treatment followup in 30 health facilities.Three focus group discussions were conducted with 23 TB experts purposefully selected from 10 sub-city health offices and health bureau. Moreover, telephonic interviews were conducted with 25 defaulted TB patients who had been attending TB treatment in the health facilities. The quantitative data were described using mean, median, percentage and frequencies. Logistic regression and exploratory factor analysis were used to extract associated factors using SPSS version 21 software. Thematic analysis was used for qualitative data analysis. Deductive and inductive reasoning was used to propose a descriptive model with substantiating literatures. Findings: Of the 601 TB patients included, 40% of them perceived they had not received a patient-centred TB care (PC-TB care) with DOTS strategy. Gender (AOR=0.45, 95%CI 0.3, 0.7), good communication (AOR=3.2, 95%CI 1.6, 6.1), treatment supporter (AOR=3.4, 95%CI 2.1, 5.5) were associated with the perceived PC-TB care. Thirty-seven percent of TB patients were following their TB treatment with feeling of dissatisfaction with DOTS strategy. Gender (AOR=2.2; 95%CI 1.3, 3.57), place of residence (AOR=3.4; 95%CI 1.6, 7.6), presence of symptoms (AOR=0.6, 95%CI 0.40, 0.94) and treatment-supporter (AOR=4.3, 95%CI 2.7, 6.8) were associated with satisfaction of TB patients. TB experts and defaulted TB patients pointed out that DOTS strategy is not providing comprehensive PC-TB care except the provision of facility choice where to follow during initiation of the treatment. DOTS delivery system inflexibility, loose integration, HCPs’ characteristic, communication skill and motivation and the community awareness were explored factor with patient centeredness of DOTS. DOTS delivery system, incompatible of diagnosis and patient beliefs were the identified categories to default. The proposed PC-TB care model core constructs are patient, community, health care providers, health care organisation and TB care delivery system. The core constructs are directed by policy and monitoring and evaluation components. Conclusion: DOTS strategy is limited to provide fully integrated PC-TB care and did not provide full satisfaction to TB patients. Therefore, a support that makes the TB care patient-centred are important and the proposed PC-TB care model needs to be tested, practiced and evaluated for its performance toward increments of patient centeredness of TB care.
