In recognition of the critical shortage of human resources within health services, community health workers have been trained and deployed to provide primary health care in developing countries. However, very few studies have investigated whether these health workers can provide good quality of care. This study investigated the knowledge and performance of health extension workers (HEWs) on antenatal and delivery care. The study also explored the barriers and facilitators for HEWs in the provision of maternal health care.
In conducting this research, a cross-sectional study was performed. A total of 50 HEWs working in 39 health posts, covering a population of approximately 195,000 people, were interviewed. Descriptive statistics was used and a composite score of knowledge of HEWs was made and interpreted based on the Ethiopian education scoring system.
Almost half of the respondents had at least 5 years of work experience as a HEW. More than half (27 (54%)) of the HEWs had poor knowledge on contents of antenatal care counseling, and the majority (44 (88%)) had poor knowledge on danger symptoms, danger signs, and complications in pregnancy. Health posts, which are the operational units for HEWs, did not have basic infrastructures like water supply, electricity, and waiting rooms for women in labor. On average within 6 months, a HEW assisted in 5.8 births. Only a few births (10%) were assisted at the health posts, the majority (82%) were assisted at home and only 20% of HEWs received professional assistance from a midwife.
Considering the poor knowledge of HEWs, poorly equipped health posts, and poor referral systems, it is difficult for HEWs to play a key role in improving health facility deliveries, skilled birth attendance, and on-time referral through early identification of danger signs. Hence, there is an urgent need to design appropriate strategies to improve the performance of HEWs by enhancing their knowledge and competencies, while creating appropriate working conditions.
It is estimated around 358,000 maternal deaths from complications of pregnancy and child birth occurred worldwide in 2008. Of these, developing countries accounted for 99% (355,000) of deaths. The vast majority of maternal deaths are due to direct obstetrical complications, including hemorrhage, infection, eclampsia, obstructed labor, and unsafe abortion. Most obstetric complications occur around the time of delivery and cannot be predicted, but can be prevented with proper medical care. In 2008, Ethiopia was among the six countries that contributed for more than 50% of maternal deaths in the world. There is no evidence suggesting maternal mortality in Ethiopia is declining. In Ethiopia, 673 and 676 maternal deaths occurred in every 100,000 live births in 2005 and 2011, respectively[4, 5].
Ethiopia is a signatory to the millennium development goals. Goal 5 targets the reduction of maternal mortality by 75% between 1990 and 2015 and calls for a target of 80% of births assisted by a skilled attendant by the year 2015. Skilled birth attendance is advocated as the ‘single most important factor in preventing maternal deaths’ and the ‘proportion of births attended by skilled health personnel’ is one of the indicators for millennium development goal 5[6, 7]. The World Health Organization (WHO) defines a skilled birth attendant as ‘an accredited health professional - such as a midwife, doctor or nurse - who has been educated and trained to be qualified in the skills needed to manage normal (uncomplicated) pregnancies, childbirth and the immediate postnatal period, and in the identification, management and referral of complications in women and newborns’.
Since the Alma-Ata Declaration on primary health care in 1978, community health worker cadres have been occurring in many countries across the globe. Nowadays, the potential roles of community health workers within primary health care have received renewed attention as a result of the HIV pandemic and due to the increasing acknowledgement of the critical shortage of human resources within health services[9–11].
Similar to other developing countries, Ethiopia has been training and deploying volunteer community health workers. With the aim of accelerating primary health care coverage and ensuring access to basic health services to the underserved rural population, the country launched a new community-based initiative called the Health Extension Program (HEP) in the year 2003. Under the umbrella of this program, cadres of community level health workers trained for 1 year, named health extension workers (HEWs), were deployed to rural areas. In relation to reducing maternal mortality, HEWs are trained on how to provide care to pregnant mothers through pregnancy, birth, and postnatal care. They are part of the formal health structure and receive a monthly salary.
Very few studies have been published on the effectiveness of these HEWs since their deployment. These studies have shown that HEWs are effective in improving immunization, family planning utilization, and antenatal care visits, but not in health facility deliveries and skilled birth attendance coverage[13–15]. Reviews have been published concerning the role of community health workers, highlighting successes and problems in other developing countries[16–19]. A systematic review done to assess the effectiveness of lay health workers showed promising benefits in promoting immunization uptake and improving outcomes for acute respiratory infections and malaria. However for other health issues such as birth attendance, there is insufficient evidence to justify recommendations which can guide policies and practices.
Considering that HEWs are not skilled birth attendants, it is recommended that the HEWs task should focus on the early identification of danger signs, danger symptoms, and complications in pregnancy and facilitating immediate referrals of pregnant women when needed. However, it is not known whether the knowledge of HEWs is adequate. Therefore, we examined the knowledge of HEWs on contents of antenatal care, danger signs, danger symptoms, and complications in three districts of Tigray region in Northern Ethiopia. In addition, we explored barriers and facilitators for HEWs in the provision of antenatal care, delivery care, and referral services.
The study employed a descriptive cross-sectional design.
The study was carried out in three selected districts of Tigray region, Ethiopia; namely Kilte Awlaelo, Saesi Tsadamba, and Degua Temben districts. Tigray is the most northern regional state of Ethiopia. The total population of the region was 4.6 million in 2010.
The Ethiopian health system is a four-level health system, characterized by the lowest level called a primary health care unit, comprising one health center and five satellite health posts, and then the district hospital, zonal hospital, and specialized hospital. Health centers are staffed with a health professionals’ team, including midlevel health professionals, for instance, health officers, nurses, midwives, sanitarians, and laboratory technicians. Ideally, there are five satellite health posts under one health center which means one health center supervises and receives referrals from five satellite health posts. Health posts are the operational units for HEWs.
Participants and sampling
Since all HEWs and health posts in the three selected districts were eligible for the study, we did not use any specific sampling technique. Rather, the focus was at ensuring participation of as many HEWs as possible. To do this we had the list of all kebeles in the districts and HEWs working in each kebele. A kebele is the smallest administrative unit in Ethiopia. It is synonymous with a village which has an average population of 5,000 people. After getting permission from Tigray regional health bureau to undertake the study, the data were then collected by travelling to each kebele to meet the HEWs for an interview.
Initially a semi-structured interview type questionnaire on paper was prepared by reviewing guidelines and manuals for HEWs. The questionnaire was divided into four sections. Section 1 was on the bio-data and characteristics of HEWs. Section 2 dealt with the availability of supplies, facilities, and logistics at health posts for maternal health care. This availability of supplies, facilities, and logistics was confirmed by observation. Section 3 was about knowledge and performance of HEWs on contents of antenatal care, birth assistance, danger symptoms, danger signs, and complications in pregnancy and making referrals. Section 4 was about barriers and facilitators for HEWs in maternal health services provision.
This hard copy questionnaire was then converted to an online questionnaire using software called Episurveyor and downloaded to a mobile phone (Nokia E71). Episurveyor is a web-based system which allows users to create a questionnaire online, download the questionnaire to a mobile phone, fill out the questionnaire using the phone, send it to a server, view data online, and export data into statistical software for further analysis. Downloading an online created questionnaire on a mobile phone was possible directly through an internet connection at the mobile phone or downloading the online questionnaire first to a personal computer (PC) and then transferring it to a phone using Universal Serial Bus (USB). All the data collected can also be saved in the memory of the mobile phone and backed up to a remote server, where it can be analyzed later.
Prior to the actual data collection, the online questionnaire downloaded on the mobile phone and using mobile phone for interview were pre-tested. The pre-test was done to assess clarity of the questions, time needed to finish the interview, and to know respondents’ comfort to be interviewed using a questionnaire on a mobile phone. This pre-test was done by interviewing five HEWs who were not included in the actual study. One major finding of the pre-test was that few of the questions had a long list of options and were found to be time-consuming when asked using mobile phones. The interviewer had to scroll down and up several times to fill out the responses of respondents. Hence, we decided to exclude these few questions from the online questionnaire and included them on paper instead. All the interviews were conducted by the principal investigator. We chose the principal investigator; because new data collectors may not have been familiar with the mobile phone approach of data collection, and we had an interest to understand very well whether mobile phone data collection can be feasible for subsequent studies in the Ethiopian context.
The collected data which was submitted to the database server was exported to SPSS version 16 (SPSS Inc, Chicago, IL, USA) for analysis. Descriptive statistics was used to summarize the data and the results were presented using frequency tables and percentages. To assess the knowledge of HEWs on contents of antenatal care counseling, danger symptoms, danger signs, and complications in pregnancy, relevant questions from the questionnaire had weights attached to them to create a composite score of knowledge. For the knowledge on contents of antenatal care counseling service, the maximum score was 25 points and points were awarded on a discrete (whole number) rather than a continuous scale, based on the number of positive responses. Interpretation of scores was based on the Ethiopian university education scoring system. We used this scoring system, because we could not find a standard scoring system for evaluating the HEWs’ knowledge. Hence, we used the Ethiopian university scoring system by slightly modifying it into a four-scale ranking. Respondents whose scores were 80% or more were classified as having excellent knowledge on contents of antenatal care counseling; those who scored between 60% and 79% were classified to have good knowledge; those who scored between 45% and 60% were classified to have fair knowledge; and those who scored 45% and below were classified as having poor knowledge. We slightly modified the Ethiopian university scoring system into a four-scale ranking for convenience because the Ethiopian scoring system has a long list of levels. A similar approach was used to interpret the knowledge of HEWs on danger symptoms, danger signs, and complications in pregnancy. Additional interpretations of scores were also made using the mean values of respondents’ knowledge. The mean and median values for the knowledge scores were virtually the same.
The study was approved by an ethical review committee at the Tigray regional health bureau in Ethiopia. The purpose of the study and the use of mobile phones were explained to each respondent. A verbal consent to participate in the study was obtained from each respondent. Participants were also informed about their right to withdraw from the study at any time of the data collection if they felt any discomfort.
Characteristics of HEWs
A total of 50 out of 68 HEWs working in 39 health posts which cover a population of approximately 195,000 people were interviewed. The remaining 18 (26.5%) were not present in their working place or kebele during the period of data collection for different reasons such as meetings, training, maternity leave, or social reasons. All respondents were women and their age ranged from 22 to 38 and the mean age was 26.36 (SD: ±4). Thirty-six (72%) of them were married. Almost half (48%) of them had at least 5 years of work experience as a HEW.

The HEWs of Ethiopia play a rather small role in assisting births. On average, a HEW assisted approximately six births per 6 months. Most deliveries took place at home without the necessary professional help or the necessary facilities. The HEWs knowledge on danger symptoms, danger signs, and complications in pregnancy was poor. In relation to this, it was indicated that HEWs rarely referred a pregnant woman to a health center. Very few HEWs received professional support on obstetric care from a midwife.
Studies[13–15] showed that the deployment of HEWs has improved some aspects of maternal and child health such as family planning utilization, immunization uptake, and the number of antenatal care visits but not in health facility deliveries and skilled birth attendance coverage. Nevertheless, these studies did not explore the reasons for HEWs’ low performance in promoting health facility deliveries and skilled birth attendance. Our study showed that one possible reason for the low performance of HEWs in stimulating behavioral change among the community and facilitation of referrals could be their poor knowledge on contents of antenatal care, danger signs, danger symptoms, and complications in pregnancy. Because of their poor knowledge, HEWs may not convince pregnant women to have birth planning and preparedness to give birth at health facilities and assisted by skilled birth attendant. In addition, the HEWs may experience that the public still prefers to give birth at home; despite the fact that the importance of institutional delivery has been discussed with the clients. This choice might be preferable considering the poor knowledge of the HEWs and lack of basic infrastructures at health posts, but it may be also due to a deep-rooted behavior and preference of the community to give birth at home. Given the HEWs are the key and main provider of primary health care services to the rural community in Ethiopia, improving their competency and effectiveness on maternal health care is urgently needed. A study conducted among community health extension workers in Nigeria showed that community health workers, who were backed by telephone consultations and working under the direct supervision of doctors, can improve quality of care to the satisfaction of most of their patients. The recent introduction of mobile phones could provide new opportunities for two-way communication between front-line health workers such as HEWs and skilled birth attendants such as midwives in health centers. However, further researches are needed to investigate the potential impact of mobile phone-based applications in improving the performance of HEWs.
Looking from the HEWs’ perspective, our study showed the absence of further education to improve their career and knowledge, earning low salary, and work load were noted to be the main factors that hindered the HEWs from providing good quality of care. Therefore, it may be unrealistic to expect HEWs to play a key role in the improvement of maternal health care without addressing their needs in career promotion and other monetary incentives. Similar findings were observed in other studies on similar initiatives[18, 19, 23]. These studies showed that continuous training, transport means, adequate supervision, and motivation of community health workers through the introduction of financial incentives are among the key factors to improve the work of community health workers. Nevertheless, more studies are needed before we can be sure what the best and most cost-effective strategy is to improve the quality of care provided by the HEWs.
Some limitations of this study deserve attention. Although this study was carried out in rural districts, these districts were relatively near to urban towns. We also did not investigate actual care given by HEWs for example by non-participant observation. Presumably the situation is more severe in very remote areas and a similar study like ours, which included non-participant observation, showed that HEWs performed less well when compared to their reported knowledge. Therefore, although the situation observed in our study was far from ideal, we assume that the knowledge and performance of HEWs might be poorer in reality.
We adapted the Ethiopian university scoring system to interpret HEWs’ knowledge on contents of ANC counseling, danger signs, danger symptoms, and complications in pregnancy. Although it might seem illogical to use the university scoring system for HEWs, it has no influence on the description we made, because basically we adapted the knowledge questions in the assessment from the guidelines, manuals, and log books of HEWs. All the knowledge questions were about the contents of ANC counseling, danger symptoms, danger signs, and complications that are expected to be known by HEWs.
Eighteen (26.5%) of the 68 HEWs who were working in the 39 health posts were not present in their working place or kebele during the period of data collection. They moved away from their working place for meetings, training, maternity leave, or social reasons. Their absence was not because they had different characteristics from the HEWs who were interviewed. Hence their exclusion from our study is not likely to influence the findings in this study.
In this study we explored the barriers and facilitators for HEWs in the provision of maternal health services through a questionnaire. However qualitative assessment either through focus group discussions or in-depth interviews with the HEWs might have been preferable approach to explore these barriers and facilitators. Hence, we recommend further qualitative studies in this regard.
HEWs knowledge on contents of antenatal care counseling, danger symptoms, danger signs, and complications in pregnancy was poor and there was no good referral system. Hence, there is an urgent need to design appropriate strategies to improve the performance of HEWs by enhancing their knowledge and competencies, while creating favorable working conditions for HEWs in the rural areas.
