Background
An important step in improving health outcomes in both the short and long term is increasing healthcare access [
1]. The magnitude of the association between the use of health services and health outcomes, however, is influenced by the quality of the services provided, the timeliness of receiving treatment and follow-up care [
2]. As stipulated in the Sustainable Development Goal (SDG) 3, achieving universal health coverage has become a global agenda. This is to ensure that in times of need, all persons have access to quality health services and are shielded from the financial burdens of health care expenses [
3]. In recent decades, several low-and middle-income countries (LMICs) have made substantial efforts to achieve this objective by introducing a number of Social Health Protection (SHP) pre-payment systems that seek to minimize dependency on out-of-pocket payments. Ghana has emerged in sub-Saharan Africa as a leader of these health financing reforms, being the first country in the sub-region to introduce a National Health Insurance Scheme (NHIS) [
4,
5].
The Government of Ghana launched the NHIS-an initiative to provide health insurance to everyone by removing the out-of-pocket payment hurdle in 2003 and this became fully operational in 2005 [
5,
6]. Health care services were paid for predominantly via consumer fees (also referred to as cash-and-carry) prior to the implementation of this program but this arrangement disenfranchised the impoverished and disadvantaged from accessing healthcare [
7,
8]. The NHIS Act 852 (2012) urges all Ghanaians to enrol unto the health insurance scheme [
9]. Funding for the scheme mainly comes from a 2.5% national tax on goods and services and a social security tax on formal workers [
10]. Personal insurance premiums are relatively low, about US$10 per year in 2010 [
11]. In fact, all nationals must register for insurance, although those who do not register will not be punished. For certain vulnerable groups, including the elderly (defined as those over 70), people under 18, and pregnant women and their newborns, the NHIS is provided free of charge.
Considering the various pregnancy-related complications experienced by pregnant women during pregnancy, tax exemption for pregnant women’s health insurance premiums has become crucial. These include high blood pressure, severe persistent nausea, vomiting and gestational diabetes [
12]. Dealing with these complications will impose an economic burden on pregnant women in LMICs such as Ghana, which can lead to serious health complications. Despite the NHIS premium exemptions for pregnant women, unavailability of health facilities, travel cost to health facilities, perceived quality of service, travel cost to NHIS registration centres and socio-cultural factors have been found to be associated with low enrollment [
13]. It is also found that the quality of health services provided by health institutions is poor, and factors such as long waiting times, poor attitudes of health institution staff, and shortage of drugs, are all contributing to low enrollment rate of NHIS [
11,
14].
Various studies have been conducted on NHIS in Ghana. Some of these have focused on subscribers’ perception [
5,
15,
16] and determinants of enrolment [
6,
17‐
22]. Others have also investigated the retention of subscribers [
23], reducing medical claims cost [
24], sustainability of the scheme [
25], equity in accessibility [
26‐
28], variation in coverage [
29], quality healthcare assessment [
30] and trends in subscription [
13]. Despite comprehensive research on the NHIS, none of these studies have, to the best of our knowledge, focused on the position of women as to whether NHIS is helping pregnant women in accessing health services or not. It is against this background and the gap in the literature that this study seeks to test the hypothesis that NHIS is helping pregnant women in accessing health services by using the current nationally representative data–2014 Ghana Demographic and Health Survey (GDHS). Outcome of this study is anticipated to inform and strengthen the need for pregnant women to subscribe to the NHIS which can help in the reduction of maternal mortality cases, improve maternal and child health and contribute to the attainment of the SDG 3.7.
Discussion
The purpose of the study was to examine whether NHIS helps women to access health services during pregnancy. We found that in addition to NHIS subscription, ANC visits, age, educational level, wealth status and region influenced women’s perception of the importance of NHIS in healthcare delivery in Ghana. In terms of NHIS subscription, we found that women who had subscribed to NHIS were more likely to mention that NHIS is helping pregnant women to access health services. This confirms that NHIS is heping women to access health services. The findings support the findings of Singh et al. [
35] who carried out a study on NHIS and maternal and child health and found that pregnant women who subscribed for NHIS were more likely to consider it as important for maternal healthcare delivery. Mensah et al. [
36] and Dzakpasu et al. [
37] have already argued that the NHIS have enhanced use of maternal care in some regions of Ghana. Similarly, Dixon et al. [
38] identified that women who registered in the NHIS make more ANC visits relative to those who aren’t registered, irrespective of socio-economic and demographic characteristics. In support of the results, Duku et al. [
39] reported that the NHIS in Ghana has an exemption policy as part of its efforts to protect vulnerable populations, which relieves them, including pregnant women, from paying an annual premium. As such, many women would use maternal health care services by minimizing the financial barriers to maternal care through NHIS. The result also indicates that NHIS subscription may indeed work as a pro-poor strategy in health financing by increasing access to health care.
The study found that women who accessed ANC at least 4 times had higher odds to report that NHIS is helping pregnant women to seek health services. Although this is a cross-sectional data, this reaffirms that the NHIS is really helping pregnant women in accessing health services. The finding confirms the findings of previous studies by Dalinjong, Wang and Homer [
40] and Singh et al. [
35], who explained that in the absence of delays in providing healthcare to pregnant women, they are more likely to utilize ANC and be satisfied with using NHIS.
Women with secondary level of education and those in the richest wealth quintile had higher odds of indicating that NHIS is helping pregnant women to access health services. The finding explains the link between empowerment and easy access to healthcare. A previous study by Nasrabadi, Sabzevari and Bonabi [
41] has shown that persons who are empowered exhibit positive health outcomes, such as increased power of decision-making, freedom for making choices and responsibility acceptance, developing trust in relations, informed choice, hopefulness, speedy personal development, awareness of one’s own world, identification of one’s own strengths and abilities, feeling more powerful, higher self-confidence, higher self-efficacy, and eventually, an improved quality of life [
41].
The findings also revealed regional-level heterogeneity in the perception that NHIS is helping pregnant women access healthcare. This is characterised by significant inequities in favour of the south [
42] and these have influence on satisfaction with health services. Interestingly, pregnant women in two regions in the southern sector (Greater Accra and Eastern) and two regions in the Northern portion of the country (Northern and Upper East) showed lower odds of reporting that NHIS is helping them to access health services. Nevertheless, a previous study by Amo-Adjei et al. [
43] found that women generally had better perceptions of the quality of NHIS healthcare in northern regions (Northern, Upper East and West) compared to those in other parts of the country. This could be due to differences in accessibility and higher quality of care experience, especially in the private sector compared to the public sector [
44], which has a lower probability of being situated in the northern part of Ghana. Our finding implies that regional disparity in perception of the quality does not always lead to a positive perception towards the use of NHIS for health services. We therefore argue that the regional-level heterogeneity in perception towards the use of health services under the NHIS could be explained by other factors which can be explored in further studies.
Strength and limitations
The study’s strength lies in the use of nationally representative survey data and the use of a broad sample size that represents the current situation in a very accurate manner. We indeed, note that this study has a few limitations. First, causal inference is limited by the cross-sectional design of the study. Again, there may be other variables that may affect the perception of women that the NHIS helps pregnant women in accessing health services that were not included in this study because of their unavailability in the dataset. Finally, the answer to the dependent variable–is NHIS helping pregnant women for health services or not–rely mainly on discretionary verbal responses of the women which did not consider a specific health service but looked at access to health serices in general.
Conclusion
This present study has revealed a statistically significant association between NHIS subscription and women indicating that, it is helping pregnant women in accessing healthcare. In addition, ANC visits, age, educational level, wealth status and region influence women’s perception of the importance of NHIS in maternal healthcare access in Ghana. The findings from this study have highlighted the socio-demographic characteristics that influence women’s perception that subscribing to the NHIS is helping pregnant women in accessing health services. It is, therefore, imperative to encourage the subscription of NHIS. For example, the Maternal and Child Health Unit of the Ghana Health Service, in collaboration with non-governmental organisations dedicated to maternal and child health issues, could intensify efforts to educate pregnant women on the importance of NHIS subscription in maternal healthcare delivery.
