Access to EMs for the management of DM and CV risk management in terms of availability, patient prices, and affordability was low in all 60 surveyed facilities. The availability of LPGs and OB medicines were 34.6% and 2.5%, respectively, with most medicines well below the WHO-recommended target of 80% availability. The median patient price of LPG diabetes EMs was 0.033 USD in the PHFs and 0.095 USD in the PMOs with most LPG diabetes EMs being unaffordable in both the PHFs and PMOs based on a typical LPGWs’ daily wages.
Our findings are consistent with previous national assessments indicative of low availability of EMs for DM and other NCDs, which is one major determinant for poor glycemic control, and associated morbidity and mortality among patients with diabetes in Ethiopia. While there could be different reasons for the observed low availability, some of the reported ones include lack of attention to NCDs, limited financial resources, and weak supply systems including staff capacity and logistics management information systems, among others [24, 25]. Nevertheless, the finding is a further warning for the healthcare system to address EM availability for DM and related conditions.
Insulin is required for the survival of people with type 1 diabetes and for the enhanced control of diabetes in some patients with type 2 diabetes. It is listed as an EM in the WHO EM list as well as in the Ethiopian EML, demanding that it should be available at all the times [11, 18]. In this study, the availability of insulin products was relatively better compared to oral DM agents and was more available than previous reports from Ethiopia suggest [26–28]. The availability of insulin is comparable to those reported from other LMICs such as Uganda and Brazil [12, 29, 30].
The findings also revealed that the availability of insulin was much better in hospitals (85.2%) and pharmacies (65%) compared to HCs (8.3%) and drug stores (33.3%), similar to findings reported by M. Ewen et al [31]. This low availability in or near primary healthcare facilities which serve the majority of the population may lead to unequitable access to EMs for patients with diabetes [32]. This could lead to patients forgoing care at nearby primary healthcare facilities and travelling longer distances to hospitals and pharmacies due to the lack of EMs in nearby outlets. This could create additional barriers to access and in turn lead to lower adherence to follow up and medications [14]. This calls for efforts to ensure distribution of EMs to locations that are accessible to patients with DM.
The median price of 26 LPG medicines was 4.65 ETB in PMOs while that of 17 LPG medicines was 1.6 ETB in PHFs which indicates products in PMOs were sold at three times of median price in PHFs. Price being a key determinant of affordability, it may have indirect role in ensuring access [33]. As the cost of medicines take up the major share for DM and CV risk factors management services, developing policies that address medicine prices for patients and enhance access are critical. Some of these include introducing mechanisms to make pricing transparent, reduce medicines prices such as tax reduction and regulate prices [12].
Most EMs in both sectors were considered unaffordable, costing between 1.2- and 3.2-days’ and 1.3- and 74.1- days’ wage to cover a month's treatment in the PHFs and PMOs respectively. When EMs remain unaffordable, patients may forgo their treatment especially if they are paying out-of-pocket for their medicines, which increases the burden of DM and its complications [34]. In order to enhance access to EMs and protect citizens from the devastating diabetes complications and financial risk that have huge effect on public health, the country should work to make health care financing sustainable for its efficient operation. These may include expanding the existing community-based health insurance, initiate the social health insurance and introduce other types of health insurance [12, 35, 36].
Study Limitations
This study has some limitations. Among these is the cross-sectional nature of the study whereby the availability of data reported in this study was based on a one-day visit to surveyed medicine outlets. Hence, it is unable to reflect the average monthly or annual, or overtime availability of medicines at the outlets. Moreover, medicines median price ratios for international price comparison are not reported in this study as the existing international price reference guideline was outdated. Lastly, the affordability of medicines reported was determined by the government's lowest salary scale for an unskilled worker. Thus, this implies that medications that appear to be relatively affordable in this study may be unaffordable when other expenditures are considered. Therefore, all these limitations need to be considered while generalizing the outcomes of this study.
This study can however provide an important and clear picture to national policymakers on access to EMs for DM and other non-communicable diseases. Different strengths and dosage forms of specific medications were included in this study to circumvent WHO/HAI availability underestimation which occurs by the inclusion of limited strength of medicines. The clinical importance of surveyed medicines has been triangulated between the national EML, the WHO EML, and national and international standard treatment guidelines.
