Tuberculosis preventive treatment in eight SEAR countries - Current practices, implementation challenges and operations research priorities.

Objectives: Countries in the South East Asian region face similar challenges in control of infectious diseases. There is limited access to experiences and learnings of neighboring countries. The Indian Council - of Medical Research (ICMR) has established a Regional Enabler for the South-East Asia Research Collaboration for Health (RESEARCH) Platform for South East Asian Region (SEAR) countries to address the above issues. This paper discusses about current practices, implementation challenges and operations research priorities of Tuberculosis Preventive therapy (TPT) in eight SEAR countries. Methods: A three day workshop on "Capacity Building for TB Research under Programmatic Settings". was conducted under the aegis of this RESEARCH platform jointly ICMR and the Union which was participated by eight SEAR countries. Data were collected from a semi-structured questionnaire prior to the workshop and open discussions during the workshop. Results: The various challenges faced for TPT implementation were broadly categorized as poor demand and low level of acceptance by the beneficiary, low level of acceptance to provide TPT among the providers, challenges in ruling out active TB, issues with supply and supply chain management of diagnostic tests and drugs. Many operations research priorities like person centric TPT driven models, capacity building for improving cascade of care for latent TB infection, health system strengthening and effective risk communication were identified. Conclusion: Full implementation of the TPT guidelines requires focused attention and coordinated action from all stakeholders of the country to attain the full benefit of TB preventive therapy and the ultimate TB elimination goal.

Quantifying the potential epidemiological impact of a 2-year active case finding for tuberculosis in rural Nepal: a model-based analysis.

OBJECTIVES: Active case finding (ACF) is an important tuberculosis (TB) intervention in high-burden settings. However, empirical evidence garnered from field data has been equivocal about the long-term community-level impact, and more data at a finer geographic scale and data-informed methods to quantify their impact are necessary. METHODS: Using village development committee (VDC)-level data on TB notification and demography between 2016 and 2017 in four southern districts of Nepal, where ACF activities were implemented as a part of the IMPACT-TB study between 2017 and 2019, we developed VDC-level transmission models of TB and ACF. Using these models and ACF yield data collected in the study, we estimated the potential epidemiological impact of IMPACT-TB ACF and compared its efficiency across VDCs in each district. RESULTS: Cases were found in the majority of VDCs during IMPACT-TB ACF, but the number of cases detected within VDCs correlated weakly with historic case notification rates. We projected that this ACF intervention would reduce the TB incidence rate by 14% (12-16) in Chitwan, 8.6% (7.3-9.7) in Dhanusha, 8.3% (7.3-9.2) in Mahottari and 3% (2.5-3.2) in Makwanpur. Over the next 10 years, we projected that this intervention would avert 987 (746-1282), 422 (304-571), 598 (450-782) and 197 (172-240) cases in Chitwan, Dhanusha, Mahottari and Makwanpur, respectively. There was substantial variation in the efficiency of ACF across VDCs: there was up to twofold difference in the number of cases averted in the 10 years per case detected. CONCLUSION: ACF data confirm that TB is widely prevalent, including in VDCs with relatively low reporting rates. Although ACF is a highly efficient component of TB control, its impact can vary substantially at local levels and must be combined with other interventions to alter TB epidemiology significantly.

Feasibility of implementing public-private mix approach for tuberculosis case management in Pokhara Metropolitan City of western Nepal: a qualitative study.

Background: The Public-Private Mix (PPM) approach is a strategic initiative that involves engaging all private and public health care providers in the fight against tuberculosis using international health care standards. For tuberculosis control in Nepal, the PPM approach could be a milestone. This study aimed to explore the barriers to a public-private mix approach in the management of tuberculosis cases in Nepal. Methods: We conducted key informant interviews with 20 participants, 14 of whom were from private clinics, polyclinics, and hospitals where the PPM approach was used, two from government hospitals, and four from policymakers. All data were audio-recorded, transcribed, and translated into English. The transcripts of the interviews were manually organized, and themes were generated and categorized into 1. TB case detection, 2. patient-related barriers, and 3. health-system-related barriers. Results: A total of 20 respondents participated in the study. Barriers to PPM were identified into following three themes: (1) Obstacles related to TB case detection, (2) Obstacles related to patients, and (3) Obstacles related to health-care system. PPM implementation was challenged by following sub-themes that included staff turnover, low private sector participation in workshops, a lack of trainings, poor recording and reporting, insufficient joint monitoring and supervision, poor financial benefit, lack of coordination and collaboration, and non-supportive TB-related policies and strategies. Conclusion: Government stakeholders can significantly benefit by applying a proactive role working with the private in monitoring and supervision. The joint efforts with private sector can then enable all stakeholders to follow the government policy, practice and protocols in case finding, holding and other preventive approaches. Future research are essential in exploring how PPM could be optimized.

Health related quality of life and associated factors with medication adherence among tuberculosis patients in selected districts of Gandaki Province of Nepal.

BACKGROUND: Tuberculosis is one of the significant public health problems of Nepal. Adherence to medication is very important for improving quality of life and preventing complication. Adherence to tuberculosis medications has significant economic and therapeutic consequences as non-adherence patients are at greater risk of developing complications which affect their health status and overall quality of life. The study aims to determine the factors associated with medication adherence and its effect on health related quality of life among tuberculosis patients in selected districts of Gandaki Province. METHODS: A health facility based cross-sectional study was carried out among 180 tuberculosis patients registered under DOTS and receiving treatment more than or equal to 60 days. WHOQOL-BREF tools to assess quality of life and Morisky medication adherence scale (MMAS-8) was adopt to assess medication adherence. Data was entered in Epi-data and analysis was performed with the help of the Statistical Package for Social Science (SPSS). The odds ratio with a 95% CI was calculated and p-value of <0.05 was considered as cutoff for statistical significance. RESULTS: A total 180 TB patients were participated in this study. Overall quality of life ranges from 10.75 to 89.25 with Mean ± SD as 55.96 ± 14.65. More than three-fourth (79.4%) respondents were adhere to medication. Medication adherence and health related quality of life was found statistically significant with relationship with health workers, favourable time at DOTS centre, absence of co-infection. Participants who were highly adhered to medication had good quality of life. CONCLUSION: Majority of tuberculosis patients adhering to medication had good quality of life. Especial emphasis should be given to tuberculosis patients with co-infection, health workers should behave friendly and provide appropriate counselling in order to maintain the medication adherence and quality of life.

Barriers to Treatment Compliance of Directly Observed Treatment Shortcourse among Pulmunary Tuberculosis Patients.

BACKGROUND: Treatment compliance is an important aspect for tuberculosis prevention and control. Poor compliance to treatment can lead to the development of drug-resistant tuberculosis. The aim of this study was to explore the factors affecting treatment compliance for tuberculosis patients. METHODS: Facility based unmatched case control study was done among the forty non-compliance and eighty compliance pulmonary tuberculosis patients registered at selected directly observed treatment short-course centers of six districts. Data were collected using in-depth interview guideline with the tuberculosis focal person and Focus Group Discussion with tuberculosis patients. RESULTS: A total of 120 respondents, 40 cases and 80 controls were enrolled in the study. About 72.5% of the cases and 56.2% of the controls were male. Five significant independent risk factors for non-compliance to TB treatment were identified. The qualitative session confirmed geographical barriers, inaccessibility to health facility, economic barriers, difficulty in convincing people, knowledge about Directly observed treatment shortcourse program, longer medication period, migration and stigma as a major barrier for treatment compliance. CONCLUSIONS: Wider ranges of barriers are prevalent in context of tuberculosis treatment pathway and outcome. Knowledge of the tuberculosis patients and attitude of the family plays a vital role in treatment compliance. Directly observed treatment shortcourse playing tremendous role to ensure treatment adherence has been identified as major barrier to adherence as well. Enablers of adherence need to be emphasized to address the barriers.
