Just imagine a world in which an infection due to ordinary simple bacteria can be fatal, where diseases that could have easily been treated from afar deprive people of their lives since the medicines required are not accessible. That is the reality for 2 billion persons who lack access to essential medicines worldwide. Neither are these advanced medicines nor experimental medication, but instead, lifesaving common drugs for pneumonia, malaria, HIV/AIDS, and the like.
Essential Medicines: What are Essential Medicines?
According to the World Health Organization (WHO), essential medicines are those needed to provide priority healthcare needs of a population. Such medicines are chosen from other medicines that ensure a certain degree of efficacy, safety, and low price for the country so they can be made available to all. However, after many years of focus on this area, many people still lack such drugs, especially in poorer countries.
The Problem: A Global Health Crisis
Access to the drugs selected has improved over the years but is still mainly inegalitarian. Today, more than half of the people in many low-income regions, mostly in Africa and Asia, are systematically barred from obtaining the medicines they need. As a result:
Preventable deaths: Millions die each year because diseases that can be treated by available drugs are not treated in time.
Chronic illness: Many individuals suffer long-term illness, reducing their quality of life and potential hours for work.
Economic burden: Families are usually at the poverty level, as it is too expensive for them to afford the high cost of treatments available, thereby causing a vicious circle of illness and poverty.
Why Is Access So Difficult?
A number of interlocking factors explain why essential medicines can't easily reach people in poor countries:
Weak healthcare systems: The underfunding of healthcare systems results in insufficient hospitals and clinics, ensuring that few medicines are available.
Expensive medicines: Even generic drugs can be unaffordable.
Supply chain issues: Drugs are manufactured but fail to reach the end users due to a lack of organized storage, transport, or distribution mechanisms.
Lack of information: Healthcare providers and patients may lack adequate information regarding the drugs, leading to improper use or non-use.
History and the Present Scenario
The gap in essential medicines has persisted for decades. Although the WHO first published its list of essential medicines back in 1977, and that list has dramatically expanded, the promise of universal access remains elusive.
Most low- and middle-income countries (LMICs) are characterized by poor infrastructure, inadequate and untrained healthcare workforces, and unreliable supply chains. According to a WHO report, even with worldwide support and resources provided in the form of guidelines, many countries still fail to deliver life-saving drugs to their populations.
Healthcare Infrastructure Challenges
In the majority of LMICs, the most significant barrier to access is the weakness of healthcare systems. Hospitals and clinics often lack resources, including essential medicines. Health providers may also not be adequately trained or informed to prescribe or administer medicines appropriately. This general gap in education and training leads to inappropriate drug use, further exacerbating the problem.
Pricing and Availability
A major hindrance is the high price of medicines, including those classified as generics. Most LMICs import drugs and are thus sensitive to price variations. Pharmaceutical companies typically concentrate their sales efforts in high-income countries where prices are generally higher, leaving LMICs with very few lower-priced options. Efforts to reduce prices through bulk purchasing or negotiations have begun to yield some dividends, but much more needs to be done.
Role of the International Community
The international community must play a role in bridging the gap for essential medicines.
WHO, along with its partners Médecins Sans Frontières and the Global Fund, is committed to getting essential drugs to people in LMICs. High-income nations must improve their financial contributions, share medical technologies with LMICs, and invest in the healthcare infrastructures of these countries.
Pharmaceutical companies also bear responsibility. While some companies have initiated programs to donate free or discounted medicines to LMICs, these efforts have typically been insufficient to close the gap. More comprehensive strategies from government and private sector stakeholders are needed to address the issues of price and availability.
Initiatives to Improve Access
Sustainable Financing: Increase healthcare investment to enhance the supply and affordability of essential medicines. Public health insurance schemes or international assistance can reduce out-of-pocket payments for families.
Affordable Prices: Promote generic medicines that are equally effective but significantly cheaper than branded ones. Bulk purchasing and better price negotiations will make drugs more affordable for governments and individuals.
Investment in Health Systems: The first investment should target a robust health system with appropriate infrastructure, storage facilities, and transportation to prevent medicine shortages, ensuring that inaccessible areas receive them. Additionally, healthcare professionals need thorough training to provide these medicines effectively.
Rational Selection and Use: Countries should select drugs for their essential medicine lists that respond to the needs of their populations. Educational programs for healthcare providers on proper prescribing practices will help ensure patients receive adequate orientation regarding medication use.
Future Solutions
In the near future, innovative new solutions can help fill the gap concerning essential medicines:
Technological Innovation: Digital health solutions, such as telemedicine and e-pharmacies, can enhance medication accessibility in geographically hard-to-reach areas. WHO promotes digital health initiatives for optimizing healthcare resource distribution and management.
Collaboration: Governments must work with pharmaceutical companies to foster transparency and break through supply chain bottlenecks, ensuring affordable medicines are available. Public-private partnerships can also spur innovation in drug production and distribution.
Domestic Production: Promoting local production of essential medicines can reduce reliance on foreign markets and stabilize supply, creating favorable price conditions. India and China have established robust pharmaceutical industries that manufacture generics at a low-cost scale.
Policy Reforms: Health policy should prioritize increasing access to essential medicines for everyone in the country. Removing taxes and tariffs on necessary medicines can significantly lower their prices.
Widening the Lens: The Five Areas of Access
Five distinct dimensions must be addressed to close the essential medicine gap: availability, affordability, accessibility, acceptability, and quality. The situation alerts us to not only the availability of medicine but also geographical access, rational use, and quality and safety.
Geographical Accessibility: Improve access for people in far-flung and underprivileged areas by developing local healthcare infrastructures. This includes building clinics and pharmacies, enhancing transport networks, and utilizing new delivery models such as mobile clinics and drone deliveries.
Rational Use: Promoting the appropriate use of medicines is vital. This involves educating healthcare providers about evidence-based prescribing practices and informing patients to make better treatment choices. It also addresses antimicrobial resistance, which jeopardizes the effectiveness of essential antibiotics.
Quality and Safety: Counterfeit and sub-standard medicines pose a significant public health risk. Enhancing regulatory systems, quality control procedures, and consumer awareness can ensure the safety and efficacy of essential medicines.
A Call to Action
The gaps in essential medicines represent a challenging, potentially intractable problem with no easy solutions. However, adopting a whole health system approach that integrates the five dimensions of access can lead to substantial progress toward the promise that everyone should gain access to these life-saving medicines.
It requires collaborative efforts from governments, international organizations, pharmaceutical companies, healthcare providers, and patients themselves. Filling this gap in essential medicines is not just about fulfilling a fundamental human right; it also represents an investment in human capital and global health security. Together, we can envision a future where preventable disease and suffering become mere memories, allowing all of humanity the opportunity to live healthy, productive lives.
