Tuberculosis recurrence in smear-positive patients cured under DOTS in southern Ethiopia: retrospective cohort study

Background: Decentralization of DOTS has increased the number of cured smear-positive tuberculosis (TB) patients. However, the rate of recurrence has increased mainly due to HIV infection. Recurrence rate could be taken as an important measure of long-term success of TB treatment. We aimed to find out the rate of recurrence in smear-positive patients cured under DOTS in southern Ethiopia. Methods: We did a retrospective cohort study on cured smear-positive TB patients who were treated from 1998 to 2006. Recurrence of smear-positive TB was used as an outcome measure. Person-years of observation (PYO) were calculated per 100 PYO from the date of cure to date of interview. Kaplan-Meier and Cox-regression methods were used to determine the survival and the hazard ratio (HR). Results: 368 cured smear-positive TB patients which were followed for 1463 person-years. Of these, 187 patients (50.8%) were men, 277 patients (75.5%) were married, 157 (44.2%) were illiterate, and 152 patients (41.3%) were farmers. 15 of 368 smear-positive patients had recurrence. The rate of recurrence was 1 per 100 PYO (0.01 per annum). Recurrence was not associated with age, sex, occupation, marital status and level of education. Conclusion: High recurrence rate occurred among smear-positive patients cured under DOTS. Further studies are required to identify factors contributing to high recurrence rates to improve disease free survival of TB patients after treatment.publishedVersio

Spatio-Temporal Analysis of Smear-Positive Tuberculosis in the Sidama Zone, Southern Ethiopia

Background Tuberculosis (TB) is a disease of public health concern, with a varying distribution across settings depending on socio-economic status, HIV burden, availability and performance of the health system. Ethiopia is a country with a high burden of TB, with regional variations in TB case notification rates (CNRs). However, TB program reports are often compiled and reported at higher administrative units that do not show the burden at lower units, so there is limited information about the spatial distribution of the disease. We therefore aim to assess the spatial distribution and presence of the spatio-temporal clustering of the disease in different geographic settings over 10 years in the Sidama Zone in southern Ethiopia. Methods A retrospective space–time and spatial analysis were carried out at the kebele level (the lowest administrative unit within a district) to identify spatial and space-time clusters of smear-positive pulmonary TB (PTB). Scan statistics, Global Moran’s I, and Getis and Ordi (Gi*) statistics were all used to help analyze the spatial distribution and clusters of the disease across settings. Results A total of 22,545 smear-positive PTB cases notified over 10 years were used for spatial analysis. In a purely spatial analysis, we identified the most likely cluster of smear-positive PTB in 192 kebeles in eight districts (RR= 2, p<0.001), with 12,155 observed and 8,668 expected cases. The Gi* statistic also identified the clusters in the same areas, and the spatial clusters showed stability in most areas in each year during the study period. The space-time analysis also detected the most likely cluster in 193 kebeles in the same eight districts (RR= 1.92, p<0.001), with 7,584 observed and 4,738 expected cases in 2003-2012. Conclusion The study found variations in CNRs and significant spatio-temporal clusters of smear-positive PTB in the Sidama Zone. The findings can be used to guide TB control programs to devise effective TB control strategies for the geographic areas characterized by the highest CNRs. Further studies are required to understand the factors associated with clustering based on individual level locations and investigation of cases

Cost and Cost-Effectiveness of Smear-Positive Tuberculosis Treatment by Health Extension Workers in Southern Ethiopia: A Community Randomized Trial

by HEWs in the health posts and general health workers at health facility were compared along a community-randomized trial. Costs were analysed from societal perspective in 2007 in US $using standard methods. We prospectively enrolled smear positive patients, and calculated cost-effectiveness as the cost per patient successfully treated. The total cost for each successfully treated smear-positive patient was higher in health facility ($158.9) compared with community ($61.7). Community-based treatment reduced the total, patient and caregiver cost by 61.2$8.80 (14.3 % of total cost) on health service per patient treated in the community. Conclusions/Significance: Community-based treatment by HEWs costs only 39 % of what treatment by general health workers costs for similar outcomes. Involving HEWs in TB treatment is a cost effective treatment alternative to the health service, to the patients and the family. There is an economic and public health reason to consider involving HEWs in TB treatment in Ethiopia. However, community-based treatment requires initial investment to start its implementation, training and supervision

Long-term outcome of smear-positive tuberculosis patients after initiation and completion of treatment: A ten-year retrospective cohort study

Background The status of tuberculosis (TB) patients since initiation of treatment is unknown in South Ethiopia. The objective of this study was to assess the long-term outcomes of smear-positive TB patients since initiation and completion of treatment, which includes TB recurrence and mortality of TB patients. Methods We did a retrospective cohort study on 2,272 smear-positive TB patients who initiated treatment for TB from September 1, 2002—October 10, 2012 in health facilities in Dale district and Yirgalem town administration. We followed them from the date of start of treatment to either the date of interview or date of death. Results Recurrence rate of TB was 15.2 per 1000 person-years. Recurrence was higher for re-treatment cases (adjusted hazard ratio (aHR), 2.7; 95% CI, 1.4–5.3). Mortality rate of TB patients was 27.1 per 1,000 person-years. The risk was high for patients above 34 years of age (aHR, 2.1; 95% CI, 1.2–3.9), poor patients (aHR, 1.3; 95% CI, 1.0–1.8), patients with poor treatment outcomes (aHR, 6.7; 95% CI, 5.1–8.9) and for patients treated at least 3 times (aHR 4.8; 95% CI, 2.1–11.1). The excess mortality occurred among patients aged above 34 years was high (41.2/1000 person years). Conclusion High TB recurrence and death of TB patients was observed among our study participants. Follow-up of TB patients with the risk factors and managing them could reduce the TB burden

A qualitative assessment of health extension workers’ relationships with the community and health sector in Ethiopia: opportunities for enhancing maternal health performance

Background: Health extension workers (HEWs) in Ethiopia have a unique position, connecting communities to the health sector. This intermediary position requires strong interpersonal relationships with actors in both the community and health sector, in order to enhance HEW performance. This study aimed to understand how relationships between EWs, the community and health sector were shaped, in order to inform policy on optimizing HEW performance in providing maternal health services. Methods: We conducted a qualitative study in six districts in the Sidama zone, which included focus group discussions (FGDs) with HEWs, women and men from the community and semi-structured interviews with HEWs; key informants working in programme management, health service delivery and supervision of HEWs; mothers; and traditional birth attendants. Respondents were asked about facilitators and barriers regarding HEWs’ relationships with the community and health sector. Interviews and FGDs were recorded, transcribed, translated, coded and thematically analysed. Results: HEWs were selected by their communities, which enhanced trust and engagement between them. Relationships were facilitated by programme design elements related to support, referral, supervision, training, monitoring and accountability. Trust, communication and dialogue and expectations influenced the strength of relationships. From the community side, the health development army supported HEWs in liaising with community members. From the health sector side, top-down supervision and inadequate training possibilities hampered relationships and demotivated HEWs. Health professionals, administrators, HEWs and communities occasionally met to monitor HEW and programme performance. Expectations from the community and health sector regarding HEWs’ tasks sometimes differed, negatively affecting motivation and satisfaction of HEWs. Conclusion: HEWs’ relationships with the community and health sector can be constrained as a result of inadequate support systems, lack of trust, communication and dialogue and differing expectations. Clearly defined roles at all levels and standardized support, monitoring and accountability, referral, supervision and training, which are executed regularly with clear communication lines, could improve dialogue and trust between HEWs and actors from the community

Patient and community experiences of tuberculosis diagnosis and care within a community-based intervention in Ethiopia: a qualitative study

Background The Ethiopian TB control programme relies on passive case finding of TB cases. The predominantly rural-based population in Ethiopia has limited access to health facilities creating barriers to TB services. An intervention package aimed to bring TB diagnosis and treatment services closer to communities has been implemented through partnership with health extension workers (HEWs). They undertook advocacy, communication and social mobilization (ACSM) activities, identified symptomatic individuals, collected sputum, prepared smears and fixed slides at community level. Field supervisors supported HEWs by delivering smeared slides to the laboratory, feeding back results to the HEWs and following up smear-negative cases. Patients diagnosed with TB initiated treatment in the community, they were supported by supervisors and HEWs through the local health post. Case notification increased from 64 to 127/100,000 population/year. Methods This qualitative study assessed community members’ treatment seeking behaviour and their perceptions of the intervention. In-depth interviews (n=36) were undertaken with participants in six districts. Participants were clients of the community-based intervention, currently on TB treatment or those screened negative for TB. Transcripts were translated to English and a thematic analytical framework was developed guided by the different steps symptomatic individuals take within the intervention package. Coding was done and queries run using NVivo software. Results Prior to the intervention many patients with chronic cough did not access TB services. Participants described difficulties they faced in accessing district level health facilities that required travel outside their communities. Giving sputum samples and receiving results from within their home communities was appreciated by all participants. The intervention had a high level of acceptability; particularly clear benefits emerged for poor women and men and those too weak to travel. Some participants appeared to prefer a diagnosis of TB, this is likely because receiving a negative smear microscopy result brought further uncertainty and necessitated seeking further investigation. Conclusions There is evidence rural populations with high levels of poverty, and in particular women, are at high risk of unmet health needs and undiagnosed TB. Embedding TB services within communities was an acceptable approach for vulnerable groups experiencing poor access to health facilities. In the Ethiopian context this approach can facilitate early diagnosis and improve treatment outcomes

Exploring providers’ perspectives of a community based TB approach in Southern Ethiopia: implication for community based approaches

Abstract Background There is increasing interest in the role of close-to-community providers in supporting universal health coverage, but questions remain about the best approaches to supporting and motivating these providers, and the optimal package they can deliver indifferent contexts and support required. We report on the experiences of different health providers involved in a community based intervention to support access to tuberculosis diagnosis and treatment in Southern Ethiopia. Methods The aim of the study is to explore the experiences of health providers in delivering a community-based tuberculosis package in southern Ethiopia and to draw lessons for community-based programmes. A qualitative methodology was used. Methods included in-depth interviews (IDIs, n= 37) with all health provider groups: Community health promoters (CHPs), health extension workers (HEWs), district supervisors and laboratory technicians were undertaken to obtain a detailed understanding of the experiences of providers in the community based tuberculosis package. These were complemented with cadre specific focus group discussions (n= 3). We used the framework approach for qualitative analysis. Results The key theme that emerged was the positive impact the community-based intervention had on vulnerable groups’ access to diagnosis, care and treatment for tuberculosis. Providers found the positive feedback from, and visible impact on, communities very motivating. Other themes related to motivation and performance included supervision and support; learning new skills; team problem solving/ addressing challenges and incentives. Against the backdrop of the Ethiopian Health Extension Programme (HEP), HEWs were successfully able to take on new tasks (collecting sputum and preparing smears) with additional training and appropriate support from supervisors, laboratory technicians and CHPs. Conclusion All categories of providers were motivated by the high visible impact of the community-based intervention on poor and vulnerable communities and households. HEWs role in the community-based intervention was supported and facilitated through the structures and processes established within the community-based intervention and the broader nation-wide Health Extension Programme. Within community based approaches there is need to develop context embedded strategies to support, sustain and motivate this critical cadre who play a pivotal role in linking health systems and rural communities

Applied research on health extension workers using ehealth to strengthen equitable systems in Southern Ethiopia health

The project successfully established an eHealth system in Southern Ethiopia. It provided training for and engaging of health extension workers (HEWs), supervisors, Health Management Information System (HMIS) focal persons, and policy makers. It was conducted in Sidama and Gedeo zones in Southern Ethiopia, with Sidama zone being the intervention zone, and Gedeo the control zone. Over 60 female health extension workers were trained. Data can be collected in real-time and is accessible throughout all levels of the health system. This has created stronger links with policy makers for action. Over 200,000 rural women and men benefit from improved health services

Community participation and maternal health service utilization: lessons from the health extension programme in rural southern Ethiopia

Background Health extension workers (HEWs) are the implementers of the unique primary health care programme of Ethiopia. They facilitate community participation in maternal health service delivery via the health development army (HDA) and pregnant women forums (PWFs). As part of a quality improvement intervention, HEWs received training, guidance and supervision focused on facilitation of HDA meetings and PWFs. We aimed to assess the effect of the intervention on maternal health service utilization and explore the perceptions of stakeholders regarding efforts to enhance community participation in maternal health. Methods We conducted a mixed method study in Shebedino woreda (district), Sidama Zone, southern Ethiopia. The research team observed HDA meetings and PWFs (15), conducted in-depth interviews with 32 HEWs, 8 HEW supervisors and maternal health program managers, and conducted 8 focus group discussions (FGDs) with community members. The interviews and FGDs were recorded, transcribed, translated, coded in Nvivo and thematically analysed. We also collected quantitative data on HDA and PWF participation, antenatal care attendance and skilled delivery and analysed using Excel (Microsoft Inc, Seattle, WA, USA). Results The proportion of HDA leaders and pregnant women who attended the HDA and PWF meetings increased by 30.6% and 36% respectively, over 18 months of the intervention. The percentage of pregnant women identified and referred by HDA leaders increased from 42% to 85%, the antenatal care utilization increased from 73.4% to 77.6% and skilled delivery increased from 76.7% to 83.3%,) (p<0.05). From interviews with stakeholders, we found improved awareness about maternal health services and increased health seeking behaviour. However, lack of incentives and reporting formats for HDA leaders, absenteeism and limited support from kebele administrators constrained community participation in maternal health. Conclusion With focused training, guidance and regular supportive supervision, HEWs were able to stimulate and enhance community participation, resulting in better maternal health service utilization in rural communities. HEWs, volunteer HDAs, pregnant women and the wider community have a role to play in quality improvement of maternal health services

High utility of active tuberculosis case finding in an Ethiopian prison

SETTING: Hawassa Prison, Southern Region of Ethiopia. OBJECTIVE: To determine the burden of pulmonary tuberculosis (TB) using active case finding among prisoners. DESIGN: In this cross-sectional study, prisoners were screened for TB using a symptom screen. Those with cough of 2 weeks had spot and morning sputum samples collected for acid-fast bacilli (AFB) smear microscopy and molecular diagnostic testing (Xpert® MTB/RIF). RESULTS: Among 2068 prisoners, 372 (18%) had a positive cough screen. The median age of these 372 persons was 23 years, 97% were male and 63% were from urban areas. Among those with a positive symptom screen, 8 (2%) were AFB sputum smear-positive and 31 (8%) were Xpert-positive. The point prevalence of pulmonary TB at the prison was 1748 per 100 000 persons. In multivariate analysis, persons with cough >4 weeks were more likely to have TB (OR 3.34, 95%CI 1.54–7.23). CONCLUSION: A high prevalence of TB was detected among inmates at a large Ethiopian prison. Active case finding using a cough symptom screen in combination with Xpert had high utility, and has the potential to interrupt transmission of Mycobacterium tuberculosis in correctional facilities in low- and middle-income, high-burden countries
