Plain English summary
Giving birth with the assistance of skilled health care professionals is referred to as skilled delivery care. Skilled delivery care is important to prevent maternal deaths that result from birth-related complications. Increasing the use of skilled delivery care is advocated as an important strategy to reduce maternal mortality. However, many women in developing countries such as Ethiopia do not wish to give birth at health facilities attended with skilled health care professionals. In Ethiopia, nearly three-quarters of women give birth at home, and the rate of skilled delivery care utilization is very low. The purpose of this study was to identify the key factors that are associated with skilled delivery care utilization in a largely rural district in Eastern Ethiopia. We conducted a community based cross-sectional study which involved a face to face interview with eligible women. A total of 1294 eligible women completed the interview. Data were summarized descriptively, and the key factors associated with the use of skilled delivery care were identified using regression analysis. The results indicated that more than a quarter of the women attended skilled delivery care for their last birth. Having an educated family member, receiving maternal health education, previous use of skilled delivery care, having a best friend who used maternal care, urban residence, intended pregnancy, and antenatal care use during their last pregnancy were facilitating factors for skilled delivery care utilization. These findings highlight the need to institute measures that include these factors to improve the use of skilled delivery care.
Introduction
Globally, an estimated 303,000 women died due to pregnancy and childbirth complications in 2015, with developing countries accounting for nearly 99% of the global burden [
1]. Although most maternal deaths that result from pregnancy complications are avoidable; all pregnancies that continued to birth could face obstetric complications that might not be identified during antenatal care (ANC) check-ups. Hence, the presence of a skilled health worker at birth for every delivery remains a crucial factor for the improvement of obstetric outcomes [
2] and prevention of maternal deaths that occur during delivery [
3]. Up to one-third of maternal mortality could be prevented by the appropriate management of birth complications by skilled health workers during birth [
4].
A review of studies in Ethiopia [
5] identified very low utilization of professionally assisted delivery care at a health facility as one of the main contributing factors to the existing high burden of maternal deaths in the country. Hence, promoting skilled delivery care attendance at health facilities is an essential strategy to prevent maternal mortality [
6,
7].
Skilled delivery care attendance is low in most developing countries, with some of the lowest rates of attendance in sub-Saharan African countries [
8], where the majority of maternal deaths occur [
9]. In Ethiopia, according to a recent Demographic and Health Survey report, the proportion of women who utilized skilled birth assistance during delivery was 28% [
10]. However, the global community has set a goal of reaching 60% utilization of skilled delivery care attendance during birth for countries with the highest maternal mortality, and 90% at a global level [
11]. Based on the trend of data in the two decades before 2010, the estimated rate of annual improvement in the utilization of skilled delivery care in Ethiopia between the years 2011 to 2015 is 0.4%, which is also far lower than the average rate of improvement in other sub-Saharan African countries [
12]. Many other studies [
13‐
18] on skilled delivery care utilization in Ethiopia found less than 40% of pregnant women accessed these services.
A multitude of factors including place of residence, education, wealth status, pregnancy intention, parity, birth order, previous use of care, physical distance, and cultural barriers are associated with skilled delivery care utilization [
19‐
26]. However, there is limited evidence as to the contextual personal, social, and community factors that motivate a majority of pregnant women in Ethiopia to avoid delivering their babies with the assistance of skilled health workers. The existing evidence is restricted to identifying the comprehensive factors influencing skilled delivery care utilization and does not reflect the underlying regional variations in socio-economic, geographic, and cultural influences. Consequently, there is a need to understand the regional level contextual factors operating as barriers in the utilization of skilled delivery care, to better inform context-specific interventions. In this study, we attempt to understand the factors associated with skilled delivery care attendance by using the Andersen and Newman behavioural model of health care utilization [
27,
28]. This model typically classifies the factors that influence utilization of health care into three categories. The
predisposing factors are the demographic and social conditions that influence the person’s decision to use the service. The
enabling factors are economic circumstances that facilitate service utilization. The
need factors reflect the perceived health service needs and are related to the actual illness condition. The aim of this study was to assess the influence of these three factors on skilled delivery care utilization among reproductive-aged women in Kersa district, eastern Ethiopia.
Methods
Study area and period
The study was conducted in Kersa district, East Hararghe zone, Oromia region, eastern Ethiopia. Kersa town, the capital of the district, is located 486 kms from Addis Ababa, the capital city of Ethiopia. The total population of the district was 205,628, as of the 2014 population projection for Ethiopia. In the district, there were 38
kebeles (the lowest administrative unit in Ethiopia consisting of 5000 people or 1000 households) or so-called subdistricts. From the 38
kebeles, three were urban, and 35 were rural [
29,
30], and 24
kebeles were under the Health and Demographic Surveillance System (HDSS). There were seven health centres, 34 health posts and eight private pharmacies in the district. The health centres routinely provide the recommended packages of ANC, skilled delivery care and postnatal care. Based on a recent report from the district health office, the health coverage of the district was 80% [
31]. The study was conducted from June to August 2017.
Study design
A community-based cross-sectional study was implemented.
Population
The population for the study were all reproductive-aged women living in the Kersa district. Only women who had at least one birth within the previous 3 years, had lived in the district for more than 6 months, and had delivered their most recent baby after 28 weeks of gestation were included. Women who were critically ill, and physically or mentally disabled were excluded from the study.
Sample size and sampling procedure
The total sample size for the study (n = 1320) was primarily calculated for a study on maternal health service utilization and associated factors in Kersa district, eastern Ethiopia using different parameters. Twenty-five percent of the total 38 kebeles in the district (i.e. 10 kebeles) were included in the study to ensure optimum sample representation. Of the included kebeles, two were urban, and eight were rural. The study district was first stratified into urban and rural kebeles, and these were further classified into HDSS and non-HDSS kebeles. A proportional number of study kebeles were then selected from each stratum using simple random sampling technique. To select the individual study participants, first, the number of households having at least one eligible woman was determined in each kebele using the Health Extension Workers’ logbook. Since the number of households with eligible women varied among the included kebeles, the total sample size of the study was proportionally allocated to each selected kebele. The total calculated sample size was then proportionally allocated to each kebele based on the determined number of households with eligible women for each kebele. The study participants were drawn from the list of households having eligible women using systematic random sampling techniques. The participants were recruited at the time of the survey based on a pre-identified list of randomly selected households. In the event of two or more eligible women being in the same household, only one woman was randomly selected and interviewed to avoid intra-household correlations.

Source of data and data collection methods
A supervisor and eight enumerators were involved in the data collection process. The data were collected using a structured questionnaire administered by face to face interviews at the participant’s home. The survey questionnaire was adapted from relevant literature [
32‐
36] that addresses maternal health service utilization. Variables were measured using closed ended questions and participants were queried about basic socio-demographic variables; reproductive histories; primary health care services; health promotion and women’s autonomy; pregnancy status and maternal health service utilization; social network; and, social support. Using the translation-back-translation method, first, the original English version of the questionnaire was translated to the local language, Oromiffa. The Oromiffa version was then translated back into English by a translator who was not involved in the first phase of the translation process. The interviews were conducted using the local language. An off-line mode of digital data collection software (Survey Gizmo) installed on iPads was used to collect the responses. Kersa HDSS resident enumerators fluent in the local language conducted the individual interviews. A field supervisor and the lead author closely monitored the data collection at the field level.
Data quality control
Pre-testing of the tool was carried out on 5% of the sample of women in the adjacent district. Necessary refinements were made on the tool based on the pre-test findings. We recruited and employed experienced local data collectors and a supervisor. Intensive training was provided to the data collectors and the supervisor on the objectives of the study, methodology, and sampling procedures and how to use the iPads for collecting responses. The use of iPads during data collection prevented the potential for incomplete responses and missing values. At the field level, 10% of the interviewed women were re-interviewed by the supervisor to check the validity of the responses. During the quality check, if the supervisor found any invalid response on the Survey Gizmo, the interviewer revisited the house and interviewed the woman again. The enumerators uploaded the responses daily to the online version of Survey Gizmo. The responses were then double-checked daily by the lead author for any inconsistencies.
Data management and analysis
Data were analyzed using SPSS version 23 software package. We conducted the transformation of some of the variables to allow for undertaking a meaningful analysis. For the transformation, we used either recoding (through collapsing categories of some nominal variables and categorizing continuous variables) or creating new variables from the existing ones using statistical computation techniques. Univariate analyses were conducted to descriptively summarize the characteristics of the sample population. The existence of multicollinearity between covariates was determined using a Variance Inflation Factor value less than five. The multivariate model fitness was verified using Hosmer-Lemeshow test. Bivariate logistic regression analysis was carried out to compare utilization of skilled delivery care among different groups using p-value. Variables that showed statistical association at a p-value less than 0.05 from each set of variables in the bivariate analysis were entered into the final full multivariate logistic regression model. Two multivariate logistic regression models were fitted (Model 1 for multiparous women and Model 2 for primiparas women) to identify factors associated with skilled delivery care utilization. The measure of association using Adjusted Odds Ratios (AOR) with Confidence Intervals (CI) was used to assess the direction as well as the strength of the association between the explanatory and the outcome variables.
Ethical considerations
The study was conducted after securing ethical approval from the Human Research Ethics Committee of the University of Newcastle, Australia and the Institutional Health Research Ethics Review Committee of College of Health and Medical Sciences, Haramaya University, Ethiopia. Informed verbal consent was obtained from each respondent before commencing the interviews. The confidentiality of the respondents was ensured by avoiding personal identification details. During house-to-house interviews, the participants’ privacy was maintained by carrying out the interviews in a separate place in their residence where auditory and visual privacy was assured.
Discussion
This study has attempted to explore the factors that influence the uptake of skilled delivery care among reproductive-aged women in a predominantly rural district in eastern Ethiopia; and definitively quantify use. Having an educated family member; receiving education on maternal health; previous use of skilled delivery care; and, best friend’s use of maternal care were significantly associated predisposing factors. Place of residence was the only significantly associated enabling factor. The significant need factors were pregnancy intention and ANC attendance for the most recent pregnancy.
The results of the current study showed that the utilization of skilled delivery care among reproductive-aged women was 30.8%. This figure reflects findings of an Ethiopian national Demographic and Health Survey report [
10], where 28% of the women delivered their most recent baby with the assistance of a skilled provider; as well as a study conducted in Southern Ethiopia [
18] in which 31% of women utilized skilled delivery care during their delivery. However, our result is higher than several other studies in Ethiopia [
14,
15,
37,
38]. The relatively higher level of skilled delivery care utilization in our study may reflect current efforts to reduce home delivery using financial penalties for traditional birth attendants and local pregnant women who opt for home births. Moreover, the evolution of the Women’s Development Army network at the village level might have contributed to better uptake of skilled delivery care through health discussions within the network during regular meetings. The varying level of service uptake underscores the requirement for local-level research to highlight the setting-specific factors that either impede or facilitate service utilization, thereby informing the development of locally suitable programs.
The findings of the present study demonstrate that the predisposing factors associated with skilled delivery care utilization were: having an educated family member: receiving education on maternal health: previous use of skilled delivery care: and, best friend’s use of maternal care. Multiparous women who have an educated family member in their household have increased odds of using skilled delivery care. The influence that the educated family member had on the woman’s acceptance of utilizing material care is paramount. It has been shown [
39] that living in close proximity to people with a higher level of education can strongly influence the health service seeking behaviour of women. People with more education tend to have healthier behaviours, and good knowledge and understanding about the importance of health care utilization [
40]. In relation to this, primiparous women who had received education on maternal health have increased odds of skilled delivery care utilization than primiparous women who had not received maternal health education. Educating women about maternal health increases their understanding of the importance of attending maternal health services; and the possible catastrophic consequences of pregnancy or birth complications; contributing to their acceptance and uptake of skilled delivery care. This positive impact of maternal health knowledge on the uptake of skilled delivery care has been evidenced in a previous study in Nepal [
41].
Previous experience of using skilled delivery care was significantly associated with skilled delivery care utilization. The finding may indicate that women perceived the delivery care services they had received during the previous birth to be quality and appropriate. The association of previous care experience with future use of skilled delivery care might also reflect the confounding effect of accessibility and availability of services. The women who previously used skilled delivery care that subsequently attend the same service might already have better accessibility to the service, which continues to be available for the subsequent births, unlike women who do not use the service. However, in a study conducted in northwest Ethiopia [
42] contrasting results were found, in that previous attendance of delivery care had a limited role in increasing the uptake of skilled delivery care for the subsequent birth. This difference may highlight the variation in terms of quality of care at different levels of primary health care facilities in Ethiopia. Moreover, in Ethiopia, concerted efforts should be made to improve the quality of obstetric care at health facilities to increase the utilization of skilled delivery care.
Our findings showed that the best friend’s non-use of maternal care is significantly associated with poor uptake of skilled delivery care. The result was comparable with a study conducted in Mali [
39], where women’s health-seeking and utilization behaviour towards maternal care use was significantly influenced by the care-seeking practices of the surrounding people in their areas of residence. Friends are often connected through providing moral support to one another which influences the decision either to refuse or accept a temptation [
43]. Women are more likely to adopt unhealthy/healthy behaviours from their best friends than strangers [
44], especially in regard to gendered issues they experience in common, such as pregnancy or birthing. During their interactions with friends, fear and stigma are decreased, allowing women to freely discuss their delivery choices and therefore a adopt bad or good care-seeking behaviour. This implies that there is a possible benefit in organizing maternal health programs that target networks at the community level, as opposed to individuals. The Women’s Development Army network, already established in most districts of Ethiopia, is an ideal platform and resource to facilitate such programs. Peer education programs customised specifically for women’s social networks at the village level have great potential to accelerate improved attendance of skilled delivery care.
We also revealed in this study that place of residence is a significantly associated enabling factor for skilled delivery care utilization. Urban women have increased odds of utilizing skilled delivery care compared to rural women. The association of urban residence with better uptake of maternal care is consistent with the findings from other studies in Ethiopia [
18,
20,
42,
45], and elsewhere in sub-Saharan Africa [
46,
47] where the odds of skilled delivery care utilization is very low among rural-dwelling women compared to urban women. Better awareness of, and access to, maternal care may account for much of the difference between urban and rural women’s uptake of skilled delivery care. Additionally, as urban women generally tend to have a higher level of economic status, they can better afford the financial burden associated with utilization of the service. Local efforts to improve maternal health should, therefore, focus on improving the accessibility and availability of delivery care services during birth, and the equitable distribution of health resources in urban and rural settings.
Moreover, ANC attendance for the index pregnancy was a statistically significant need factor that was associated with skilled delivery care utilization. Women who attended ANC for the index pregnancy have higher odds of attending skilled delivery care compared to women who did not attend ANC. The finding is in agreement with a swathe of other studies in Ethiopia [
14,
20,
42,
48,
49] where the use of ANC for the woman’s most recent pregnancy was strongly associated with an increased likelihood of attending skilled delivery care for the most recent birth. The women had physical interactions with the health workers and the facility during ANC that might, in turn, have helped them become more confident and familiar with the health facility allowing them to seek skilled delivery care [
39]. Moreover, during the ANC check-up, the women had the opportunity to receive advice and information related to the benefits of skilled delivery care as well as the potential occurrence of obstetric problems during delivery which could increase their perceived susceptibility and motivate them to attend the care [
37,
50,
51].
Women with unintended pregnancies have lower odds of skilled delivery care utilization compared to women with intended pregnancies. These findings are consistent with those of a previous Ethiopian study [
19], which showed that skilled delivery utilization is higher among women who have intended rather than unintended pregnancies. The actual linking mechanism between pregnancy intentions and the use of skilled delivery and other maternal care is unclear; however, it could be related to women’s ability to having control over both their reproductive life and household resources [
52].. In addition, some women with unintended pregnancies may consider abortion as an alternative to maternal health service use. Unintended pregnancies are highly indicative of an unmet need for family planning; thus, access to appropriate family planning services should be improved.
Strengths and limitations
Limiting the reference time for retrospective questions to 3 years could minimize the introduction of recall bias. The use of relatively higher sample size has given adequate power to the study. We used a digital survey tool with iPads to collect the data, which improved the quality of the data by ensuring its completeness and consistency. Incorporation of a greater number of predictor variables into the final multivariate model ensures better controlling for confounding factors. As the interviewers were resident HDSS data collectors who regularly interact with the community, social desirability bias might not be ruled out. Due to the social desirability bias, women might have tended to provide favourable responses regarding the current or past of use of delivery care and be hesitant to share their negative care experiences. Due to the cross-sectional nature of the survey design, establishing a causality inference is also difficult. Regardless of the limitations of the study, we believe that the current survey provides a quite strong indication of the factors influencing skilled delivery care utilization in a rural setting in Ethiopia.
