National Assessment of the Health Extension Program in Ethiopia: Study Protocol and Key Outputs

BACKGROUND: The Health Extension Program (HEP) was introduced in 2003 to extend primary health care services by institutionalizing the former volunteer-based village health services.However, this program is not comprehensively evaluated.MATERIALS AND METHODS: The 2019 comprehensive national assessment of HEP involved (1) assessment through quantitative and qualitative primary data, (2) a thorough systematic review of the HEP literature, and (3) a synthesis of evidence from the two sources. The assessment included household survey(n=7122), a survey of health extension workers (HEWs) (n=584)_, and an assessment of health posts (HPs)(n=343) and their supervising health centers (HCs)(n=179)from 62 randomly selected woredas. As part of the comprehensive assessment.OUTPUT AND RESULTS: The outputs were (a) full and abridged reports, (b) 40 posters, (c) seven published, three under review scientific papers and (d) seven papers in this special issue. During the one-year period preceding the study, 54.8% of women, 32.1% of men, and 21.9% of female youths had at least a one-time interaction with HEWs. HPs and HEWs were universally available. There were critical gaps in the skills and motivation of HEWs and fulfillment of HP standards: 57.3% of HEWs were certified, average satisfaction score of HEWs was 48.6%, and 5.4% of HPs fulfilled equipment standards. CONCLUSIONS: The findings informed policy and program decisions of the Ministry of Health, including the design of the HEP Optimization Roadmap 2020­2035 and the development Health Sector Transformation Plan II. It is also shared with global community through published papers

The Quality of Logistics Management Information System and the Availability of Tracer Drugs at Health Posts in Rural Ethiopia: A Mixed-Method Study

BACKGROUND: Proper implementation of the logistics management information system (LMIS) would facilitate access to essential pharmaceutical products. It also prevents wastage at health posts. The aim of this study was to assess the implementation of the LMIS and the availability of tracer drugs at health posts in rural Ethiopia. METHODS: We employed a cross-sectional descriptive design with a mixed-method approach. The data used for this paper was collected from March to May 2019 as part of the National HEP assessment. The study involved 343 health posts randomly selected from nine regions of Ethiopia. Women's Development Army members and household heads participated in the qualitative study (i.e. in FGD and KII). The quantitative data were exported from Open Data Kit (ODK) to Stata 15.1 for statistical analysis, and the qualitative data were entered into NVivo 12 and analyzed using thematic content analysis. RESULTS: Of the health posts, 59.4% had a space for storing drugs; less than half (41.9%; 95% confidence interval (CI) [36%, 48%]) had a functioning refrigerator. The mean percentage of the availability of selected tracer drugs at health posts was 59.6%, with a 95% CI (58.9%, 60.3%). Bin cards were available at 43% (95% CI [40%, 46%]) of health posts, and among these, only 27.5% of the health posts adequately used the bin cards. CONCLUSION: The absence and poor use of LMIS tools was observed at health posts. Proper implementation of the LMIS has the potential to improve the availability of essential drugs that, in turn, improve health post level delivery of health services.

Does Combining Antenatal Care Visits at Health Posts and Health Centers Improve Antenatal Care Quality in Rural Ethiopia?

BACKGROUND: Even though quality maternal care is crucial for the well-being of women and their newborns, the inferior quality of antenatal care in rural Ethiopia is a timely concern. This study aimed to investigate the effects of combining antenatal care visits at health posts and health centers on improving antenatal care quality in rural Ethiopia. METHODS: Using the 2019 Ethiopia Health Extension Program assessment done by MERQ, we extracted and analyzed the survey responses of 2,660 women who had received at least one antenatal visit from a primary health care unit. We measured the cumulative count of quality of antenatal care using the Donabedian model. To model the differences in the quality of antenatal care at health posts and health centers, we used zero truncated Poisson regression and reported incidence risk ratios with their 95% confidence intervals. RESULTS: The quality of antenatal care increased by 20% (adjusted IRR= 1.20 [1.12­1.28]) when antenatal care reception was mixed at health posts and health centers, compared to those who received all antenatal care only from health posts. Quality differences based on socioeconomic status and setting variations were observed as predictors of quality of care, even if women received antenatal care at both health posts and health centers. CONCLUSIONS: Combining antenatal care provision from health posts and health centers should be sustained as one of the antenatal care quality improvement strategies in rural parts of Ethiopia while ensuring the equitable provision of quality care across socioeconomic groups and between agrarian and pastoral settings.

Relevance of the Health Extension Program to the current Health Needs and Evolving Demands of Rural Ethiopia: A Mixed-Method Analysi

BACKGROUND: Ethiopia has been implementing a health extension program (HEP) to respond to the high maternal and child mortality in rural communities. HEP has brought tremendous contributions to improved access and coverage of primary healthcare in the last 15 years. Despite its attributions, attention to HEP has declined in recent years due to several reasons. This study is designed to explore HEP's relevance to the current healthcare needs of the rural communities. METHODS: This study is a nested cross-sectional mixed method to the overall HEP's evaluation between March and May 2019. Descriptive statistics were used on qualitative and quantitative assessment. A literature review supplemented the assessment. A representative quantitative sample of 11,746 women, men, and young girls; a qualitative sample of 268 key informants from Kebele administrators, HEWs, program people in the health system and focus groups from community leaders, men and women from 185 Kebeles in 62 woredas were selected. A thematic approach was used for qualitative analysis. RESULTS: Rural communities and program managers asserted that HEP's service packages with the existing service delivery modalities were relevant. Eighty-two percent of men and women and 77% of young girls confirmed this relevance. Besides the existing packages, additional curative services for adults and children were recommended with emphasis on the pastoralist community. HEP's service uptake has declined as over 86% of targeted rural communities bypassed HPs due to unavailability of services and capacity problems of HEWs. CONCLUSION: The current HEP packages with the existing service delivery modalities are still relevant to the rural communities' health needs. However, on-going changes to address the evolving demands of the targeted rural communities are crucial

EMJ series on statistics and methods: variables, populations and samples

This the first article in the EMJ Series on Statistics and Methods describes "variables" which represent different demographic and clinical characteristics of several individuals in a data set. Various attributes of quantitative and qualitative variables, including type, scale of measurement and values they may take are presented. Some descriptive statistics and graphic summaries are introduced. Pertinent examples drawn from journal articles are provided. The article also defines "population" as used in statistics and epidemiology and highlights population in size and scope in the context of the research question to be answered. It emphasizes the need for explicitly defining sampling based on the research question in a particular study. In addition, the articles introduces concepts and notations related to parameter and statistic. It highlights the need for using appropriate sampling method in selecting a representative sample of the study population and to be able to make valid inferences and generalizations. It is indicated in this articles that specific issues requiring further details will be addressed in the Series articles in subsequent Issues of EMJ

EMJ series on statistics and methods: normal distribution and the central limit theorem

This second article in the EMJ Series on Statistics and Methods dwells on the basics of sampling distribution of' variables', which are presented in detail in the preceding article in this Issue of the Ethiopian Medical Journal (EMJ). The present article highlights recommended routines that need to be undertaken in order to understand information collected in a particular study before embarking on doing complex statistical analyses. It underscores the importance of descriptive statistics as a means to getting insights into data quality and learn about the scale and distribution of different variables in a data set. The article emphasizes the need for assessing the sampling distributions of variables as a prerequisite to making decide on selection of appropriate statistical techniques for in a data set. It describes salient features of a normally distributed random variable and touches on some other probability distributions commonly used in epidemiological studies. The article also describes the central limit theorem highlighting salient points on its conceptual basis in understanding sampling distributions of sample means and the implications of using normal distribution to make inference about the population based on summary measures from a sufficiently large sample

Treatment outcome of tuberculosis patients under directly observed treatment in Addis Ababa, Ethiopia

BACKGROUND: Tuberculosis is one of the leading causes of mortality among infectious diseases worldwide. For effective tuberculosis control, it is a pre-requisite to detect the cases as early as possible, and to ensure that the tuberculosis patients complete their treatment and get cured. However, in many resource-constrained settings treatment outcome for tuberculosis has not been satisfactory. OBJECTIVE: The aim of the study was to assess the treatment outcome of tuberculosis patients and investigate the association of demographic and clinical factors with treatment success of patients enrolled in Directly Observed Treatment Short Course program in government owned health centers over the course of five consecutive years in Addis Ababa, Ethiopia. METHODS: A register based historical cohort study covering the period of July 2004 to June 2009 was conducted to determine the treatment outcome of Directly Observed Treatment Short Course in government owned health centers in Addis Ababa. Sex and age of tuberculosis patients, health center at which the patient was treated, year of treatment, type of tuberculosis for which the patient was treated, type of treatment offered to the patient, follow-up status and documented treatment outcome were extracted from the Directly Observed Treatment Short Course clinics of three randomly selected health centers. RESULT: Records of 6450 registered tuberculosis patients (n = 3147 males and 3433 females) were included in this document review. Of these patients 18.1% were reported as being cured, 64.6% were documented as treatment completed, 3.7% died during follow-up, 5.1% were reported as defaulters, 0.4% were documented as treatment failure and 8.2% were transferred out to another health institution. Treatment center and year of enrollment were significantly associated with treatment success. CONCLUSION: Year of enrollment and treatment center were significantly associated with treatment success. Although the overall treatment success obtained in this study is in line with the World Health Organization (WHO) target, continuous follow-up of patients with frequent supportive supervision during the course of treatment, and further investigate the cause for the observed difference in treatment success across treatment centers are recommended.

Trends of Tuberculosis and HIV Infections between 2004 and 2008 in Wolaita Sodo; Southern Ethiopia

In sub-Saharan Africa human immunodeficiency virus (HIV) epidemic has a major influence on tuberculosis (TB) epidemiology. Ethiopia is among the countries in the region most heavily affected by the HIV and TB. Recent evidence indicated that the HIV/AIDS epidemic may be more heterogeneous in different age categories; between males and females; across different risk groups; and/or in different geographical settings than previously believed. This heterogeneity implies that HIV/AIDS programs for a particular area should be based not only on national-level statistics; but it also needs to be geographically focused; and directed to those regions; districts or communities exhibiting higher prevalence. The current study was aimed to evaluate trends of the prevalence of HIV and TB infection in Wolaita Sodo town. This is institution based retrospective study and it covered the period of 2004 to 2008. We reviewed the medical records of 7375 patients with a diagnosis of TB and 11447 individuals screened for HIV at three heath institutions located in Wolaita Sodo town. Statistical significance of trend in proportions over the study period was evaluated by chi2 test for trend using Epi-Info version 6.03. P-value less than 0.05 was reported as being statistically significant.The prevalence of TB was 17.1(1262/7375); that of HIV was 10.7(1220/11447) and the prevalence of HIV and TB co-infection was 7.8(36/459). With the exception of 2008 annual TB cases; the prevalence of TB in Wolaita Sodo showed an overall significant decline over the study period (chi2 = 59.4; P 0.001). The prevalence of TB (P CI: 1.23 to 1.47) but not for TB infection. In the study area annual prevalence of TB; HIV and TB/HIV co-infection were significantly decreased from 2004 to 2008 in the age range of 25-44 years. However; the level of infection of these infections is still high and remains as being public health problems in the study area. Therefore; a good practice of TB and HIV control strategy adopted in the area should be strictly continued

Assessment of distribution, knowledge and utilization of insecticide treated nets in selected malaria prone areas of Ethiopia

Background: Insecticide Treated Nets (ITNs) reduce malaria related mortality and morbidity significantly. Taking this into account; the Ethiopian Federal Ministry of Health has been distributing ITNs to malaria prone areas of the country through the support of the Global Fund. Objective: To study distributional coverage and assess the knowledge and utilization of insecticide treated nets in Ethiopia. Methods: A cross-sectional study was conducted in 17 malarious districts targeted for the first phase free distribution of long lasting insecticide treats nets (LLITNs) by the Ministry of Health in 9 administrative regions from October 2005 to September 2006. Region specific list of malarious districts where MOH distributed ITNs was used as the sampling frame for stratified random sampling of districts. One kebele (sub district) was selected from each of the selected districts using simple random sampling; and 15of the total households in the selected kebeles were selected using systematic random sampling. Upon obtaining informed consent from the household head or the oldest person in the household the questionnaire was administered and information was recorded. Data were double entered using EpiData version 3 and analyzed using SPSS version 12. Results: A total of 3131 households were visited; and 51.6of the respondents were males. The overall ITN distribution and utilization were 97.6and 81.6; respectively. The majority of households (53.2) owned a single net per family; highest in Dire Dawa (93.7) and lowest in Afar (17.6). Thirty eight percent of the respondents owned two nets per household. Most of the respondents (91.1) cited that ITNs are useful to control malaria either through prevention of mosquito bites (60) or prevention of the disease (39). Conclusion: ITN distribution; utilization; knowledge of users and its acceptability were good considering the recent introduction of the products. However; the person net ratio gap should be narrowed and emphasis needs to be given to vulnerable groups
