Health extension workers improve tuberculosis case detection and treatment success in southern Ethiopia: a community randomized trial.

ABSTRACT: BACKGROUND:One of the main strategies to control tuberculosis (TB) is to find and treat people with active disease. Unfortunately, the case detection rates remain low in many countries. Thus, we need interventions to find and treat sufficient number of patients to control TB. We investigated whether involving health extension workers (HEWs: trained community health workers) in TB control improved smear-positive case detection and treatment success rates in southern Ethiopia. METHODOLOGY/PRINCIPAL FINDING:We carried out a community-randomized trial in southern Ethiopia from September 2006 to April 2008. Fifty-one kebeles (with a total population of 296, 811) were randomly allocated to intervention and control groups. We trained HEWs in the intervention kebeles on how to identify suspects, collect sputum, and provide directly observed treatment. The HEWs in the intervention kebeles advised people with productive cough of 2 weeks or more duration to attend the health posts. Two hundred and thirty smear-positive patients were identified from the intervention and 88 patients from the control kebeles. The mean case detection rate was higher in the intervention than in the control kebeles (122.2% vs 69.4%, p<0.001). In addition, more females patients were identified in the intervention kebeles (149.0 vs 91.6, p<0.001). The mean treatment success rate was higher in the intervention than in the control kebeles (89.3% vs 83.1%, p = 0.012) and more for females patients (89.8% vs 81.3%, p = 0.05). CONCLUSIONS/SIGNIFICANCE:The involvement of HEWs in sputum collection and treatment improved smear-positive case detection and treatment success rate, possibly because of an improved service access. This could be applied in settings with low health service coverage and a shortage of health workers. TRIAL REGISTRATION:ClinicalTrials.gov NCT00803322.

Project description:BackgroundDespite the emphasis placed on Community Based Tuberculosis Care (CBTC) implementation by Health Extension Workers (HEWs) within the National Tuberculosis Program (NTP) in Ethiopia, there is little evidence on contribution of HEWs on TB case notification. Therefore, this study aimed to describe the contribution of HEWs on TB case notification and its associated factors in Tigray region, Northern Ethiopia.MethodsA concurrent mixed method (quantitative and qualitative) cross-sectional study design was conducted in three randomly selected districts in Tigray region, Northern Ethiopia. Quantitative data were collected using a pre-tested semi-structured questionnaire. Qualitative data were collected using Focused Group Discussions (FGDs) and Key Informant Interviews (KIIs) to further describe the community participation and presumptive TB identification and referral system. For the quantitative data, binary logistic regression analysis was done and all variables with P-value of < 0.25 in bivariate analysis were included in the multi-variable model to see predictors of HEWs contribution to TB notification. The qualitative data were thematically analyzed using Atlas.ti version 7.ResultsIn this study, a total of 68 HEWs were included. From March 1, 2017 to February 28, 2018, a total of 427 TB cases notified in the study areas and one-third (34%) of them were notified by the HEWs referral. Provision of Community Based-Directly Observed Treatment Short course (CB-DOTS) (Adjusted Odds Ratio (AOR) = 3.63, 95% Confidence Interval (CI) = 1.18-11.19) and involvement of community volunteers on CBTC (AOR = 3.31, 95% CI = 1.10-10.09) were significantly associated with the contribution of HEWs on TB case notification. The qualitative findings indicated that high workload of HEWs, inaccessibility of TB diagnostic services at nearby health facilities, and transportation and investigation costs were identified as factors affecting for presumptive TB referral by HEWs.ConclusionsProvision of CB-DOTS and involvement of community volunteers in CBTC activities should be strengthened to improve the HEWs contribution on TB case notification. Additionally, HEWs should be empowered and further interventions of TB diagnostic services at diagnostic health facilities are needed to improve presumptive TB referral by HEWs.

Project description:BackgroundThe improvement of various health outcomes, including the reduction of maternal, neonatal, infant, and child mortality as well as the increased use of maternity and newborn health services, was significantly assisted by rural health extension workers. Implementing health extension programs and offering the community high-quality healthcare services requires job satisfaction. In the study area, there has been little research on job satisfaction and related variables. Therefore, the purpose of this study was to evaluate the degree of job satisfaction among rural health extension workers in the Hadiya zone, Southern Ethiopia, as well as associated factors.MethodsA facility-based cross-sectional study was conducted among 262 rural health extension workers from May 30, 2021, to July 02, 2021. A simple random sampling method was used to select six rural districts. Data were gathered utilizing structured interviewer-administered questions and skilled data collectors. EpiData V4.4.1 was used to store the data, and SPSS Version 25 was used for analysis. To determine the relationship between the variables, bivariate and multivariate logistic regressions were used. The association was reported using the adjusted odds ratio (AOR) with a 95% confidence interval (95%CI), and the significance level was set at a p-value of 0.05.ResultsThis study showed that 52.7% of rural health extension workers were satisfied with their jobs. Support from Keble leaders [AOR = 5.3; 95% CI (2.6, 11.1)], on-job training [AOR = 5.7, 95% CI (2.2, 14.9)], supportive supervision [AOR = 4.3; 95% CI (1.7, 10.8)] and reward or recognition [AOR = 7.4, 95% CI (3.0, 18.1)] were factors that associated with job satisfaction of health extension workers.ConclusionAccording to this study, more than half of rural health extension workers were happy with their jobs. Health extension workers' job satisfaction was affected by support from keble leaders, supportive supervision, on-the-job training, and recognition and rewards. In order to increase the happiness of the health extension workers, supporting supervision must be strengthened and the best performers must be recognized.

Project description:BACKGROUND: Governments are increasingly reliant on community health workers to undertake health promotion and provide essential curative care. In 2003, the Government of Ethiopia launched the Health Extension Programme and introduced a new cadre, health extension workers (HEWs), to improve access to care in rural communities. In 2013, to inform the government's plans for HEWs to take on an enhanced role in community-based newborn care, a time and motion study was conducted to understand the range of HEW responsibilities and how they allocate their time across health and non-health activities. METHODS: The study was administered in 69 rural kebeles in the Southern Nations Nationalities and People's Region and Oromia Region that were intervention areas of a trial to evaluate a package of community-based interventions for newborns. Over 4 consecutive weeks, HEWs completed a diary and recorded all activities undertaken during each working day. HEWs were also surveyed to collect data on seasonal activities and details of the health post and kebele in which they work. The average proportion of productive time (excluding breaks) that HEWs spent on an activity, at a location, or with a recipient each week, was calculated. RESULTS: The self-reported diary was completed by 131 HEWs. Over the course of a week, HEWs divided their time between the health post (51%) and the community (37%), with the remaining 11% of their time spent elsewhere. Curative health activities represented 16% of HEWs' time each week and 43% of their time was spent on health promotion and prevention. The remaining time included travel, training and supervision, administration, and community meetings. HEWs spent the majority (70%) of their time with individuals, families, and community members. CONCLUSIONS: HEWs have wide-ranging responsibilities for community-based health promotion and curative care. Their workload is diverse and they spend time on activities relating to family health, disease prevention and control, hygiene and sanitation, as well as other community-based activities. Reproductive, maternal, newborn, and child health activities represent a major component of the HEW's work and, as such, they can have a critically important role in improving the health outcomes of mothers and children in Ethiopia.

Project description:BackgroundDespite the expansion of health services and community-based interventions in Ethiopia, limited evidence exists about the distribution of and access to health facilities and their relationship with the performance of tuberculosis (TB) control programmes. We aim to assess the geographical distribution of and physical accessibility to TB control services and their relationship with TB case notification rates (CNRs) and treatment outcome in the Sidama Zone, southern Ethiopia.DesignWe carried out an ecological study to assess physical accessibility to TB control facilities and the association of physical accessibility with TB CNRs and treatment outcome. We collected smear-positive pulmonary TB (PTB) cases treated during 2003-2012 from unit TB registers and TB service data such as availability of basic supplies for TB control and geographic locations of health services. We used ArcGIS 10.2 to measure the distance from each enumeration location to the nearest TB control facilities. A linear regression analysis was employed to assess factors associated with TB CNRs and treatment outcome.ResultsOver a decade the health service coverage (the health facility-to-population ratio) increased by 36% and the accessibility to TB control facilities also improved. Thus, the mean distance from TB control services was 7.6 km in 2003 (ranging from 1.8 to 25.5 km) between kebeles (the smallest administrative units) and had decreased to 3.2 km in 2012 (ranging from 1.5 to 12.4 km). In multivariate linear regression, as distance from TB diagnostic facilities (b-estimate=-0.25, p<0.001) and altitude (b-estimate=-0.31, p<0.001) increased, the CNRs of TB decreased, whereas a higher population density was associated with increased TB CNRs. Similarly, distance to TB control facilities (b-estimate=-0.27, p<0.001) and altitude (b-estimate=-0.30, p<0.001) were inversely associated with treatment success (proportion of treatment completed or cured cases).ConclusionsAccessibility to TB control services improved despite the geographic variations. TB CNRs were higher in areas where people had better access to diagnostic and treatment centres. Community-based interventions also played an important role for the increased CNRs in most areas.
