Identifying market risk for substandard and falsified medicines: an analytic framework based on qualitative research in China, Indonesia, Turkey and Romania

Value for money of medicine sampling and quality testing: evidence from Indonesia

BACKGROUND

Substandard and falsified medicines (SFMs) are a public health concern of global importance. Postmarket surveillance in the form of medicine sampling and quality testing can prevent and detect SFM, however, there is remarkably scarce evidence about the cost and value for money of these activities: how much do they cost and how effective are they in detecting SFM?

METHODS

Between February and October 2022, Systematic Tracking of At Risk Medicines (STARmeds) collected and analysed for quality 1274 samples of 5 medicines from physical and online retail outlets in 7 Indonesian districts. We collated data on the resources consumed by STARmeds, related to all stages of medicines sampling and quality testing including design, fieldwork and laboratory analysis. We used activity-based costing principles to calculate the financial and economic cost of medicine quality surveillance from the perspective of a hypothetical medicines' regulator. We calculated the cost per day and per week of fieldwork, per sample collected and per substandard sample. We used bootstrapping to capture uncertainty in the number of samples collected, by seller location type (urban, rural and online).

RESULTS

The total cost of sampling and testing medicines from the market was US$712 964 (current 2022 values). Laboratory costs represented the largest share (70%), followed by other direct costs (12%) and indirect costs (7%). On average, it costs STARmeds US$479 (95% CI US$462 to US$516) to collect one medicine sample and US$5990 (95% CI US$5601 to US$6258) to identify one substandard sample.

CONCLUSION

Our findings bring urgently needed and novel information on the cost and value for money of medicine quality surveillance. These may support planning and budgeting of the Indonesian pharmaceutical regulator, but also of regulators and researchers elsewhere, particularly in low-income and middle-income settings, as well as international organisations with health regulation and quality of care remits.

Modeling the economic burden of postpartum hemorrhage due to substandard uterotonics in Ghana

Uterotonics are essential in preventing postpartum hemorrhage (PPH), the leading direct cause of maternal death worldwide. However, uterotonics are often substandard in low- and middle-income countries, contributing to poor maternal health outcomes. This study examines the health and economic impact of substandard uterotonics in Ghana. A decision-tree model was built to simulate vaginal and cesarean section births across health facilities, uterotonic quality and utilization, PPH risk and diagnosis, and resulting health and economic outcomes. We utilized delivery data from Ghana's maternal health survey, risks of health outcomes from a Cochrane review, and E-MOTIVE trial data for health outcomes related to oxytocin quality. We compared scenarios with and without substandard uterotonics, as well as scenarios altering uterotonic use and care-seeking behaviors. We found that substandard uterotonic use contributes to $18.8 million in economic burden annually, including $6.3 million and $4.8 million in out-of-pocket expenditures in public and private sectors, respectively. Annually, the National Health Insurance Scheme bears $1.6 million in costs due to substandard uterotonic use. Substandard uterotonics contribute to $6 million in long-term productivity losses from maternal mortality annually. Improving the quality of uterotonics could reduce 20,000 (11%) PPH cases, 5,000 (11%) severe PPH cases, and 100 (11%) deaths due to PPH annually in Ghana. Ensuring the quality of uterotonics would result in millions of dollars in cost savings and improve maternal health outcomes for the government and families in Ghana. Cost savings from improving uterotonic quality would provide financial protection and help Ghana advance toward Universal Health Coverage.

An urgent need for community lot testing of lateral flow fentanyl test strips marketed for harm reduction in Northern America

BACKGROUND

Fentanyl test strips (FTS) are lateral flow immunoassay strips designed for detection of ng/mL levels of fentanyl in urine. In 2021, the US Centers for Disease Control and the Substance Abuse and Mental Health Administration stated that federal funds could be used for procurement of FTS for harm reduction strategies approved by the government such as drug checking. The market for FTS has expanded rapidly in the US and Canada. However, there is no regulatory oversight by either government to ensure proper function of FTS that are being marketed for drug checking.

MAIN BODY

Many brands of FTS have rapidly entered the harm reduction market, creating concerns about the reproducibility and accuracy of their performance from brand to brand and lot to lot. Some examples are provided in this Comment. Similar problems with product quality were observed in the mid 2000's when lateral flow immunoassays for malaria were funded in many countries and again in 2020, when COVID-19 tests were in huge demand. The combination of high demand and low levels of regulation and enforcement led some manufacturers to join the goldrush without adequate field testing or quality assurance. We argue that the harm reduction community urgently needs to set a lot checking program in place. A set of simple protocols for conducting the tests and communicating the results have been developed, and are described in the following Perspectives paper in this issue.

CONCLUSION

In the absence of governmental regulation and enforcement, the harm reduction community should implement a FTS lot checking program. Based on previous experience with the malaria diagnostic lot checking program, this inexpensive effort could identify products that are not suitable for harm reduction applications and provide valuable feedback to manufacturers. Dissemination of the results will help harm reduction organizations to ensure that FTS they use for drug checking are fit for the purpose.

The role of constraints and information gaps in driving risky medicine purchasing practices in four African countries

Substandard and falsified (SF) medical products pose a major threat to public health and socioeconomic development, particularly in low- and middle-income countries. In response, public education campaigns have been developed to alert consumers about the risks of SF medicines and provide guidance on 'safer' practices, along with other demand- and supply-side measures. However, little is currently known about the potential effectiveness of such campaigns while structural constraints to accessing quality-assured medicines persist. This paper analyses survey data on medicine purchasing practices, information and constraints from four African countries (Ghana, Nigeria, Sierra Leone and Uganda; n > 1000 per country). Using multivariate regression and structural equation modelling, we present what we believe to be the first attempt to tease apart, statistically, the effects of an information gap vs structural constraints in driving potential public exposure to SF medicines. The analysis confirms that less privileged groups (including, variously, those in rural settlements, with low levels of formal education, not in paid employment, often women and households with a disability or long-term sickness) are disproportionately potentially exposed to SF medicines; these same demographic groups also tend to have lower levels of awareness and experience greater levels of constraint. Despite the constraints, our models suggest that public health education may have an important role to play in modifying some (but not all) risky practices. Appropriately targeted public messaging can thus be a useful part of the toolbox in the fight against SF medicines, but it can only work effectively in combination with wider-reaching reforms to address higher-level vulnerabilities in pharmaceutical supply chains in Africa and expand access to quality-assured public-sector health services.

Do private health providers help achieve Universal Health Coverage? A scoping review of the evidence from low-income countries

Universal Health Coverage (UHC) is the dominant paradigm in health systems research, positing that everyone should have access to a range of affordable health services. Although private providers are an integral part of world health systems, their contribution to achieving UHC is unclear, particularly in low-income countries (LICs). We scoped the literature to map out the evidence on private providers' contribution to UHC progress in LICs. Literature searches of PubMed, Scopus and Web of Science were conducted in 2022. A total of 1049 documents published between 2002 and 2022 were screened for eligibility using predefined inclusion criteria, focusing on formal as well as informal private health sectors in 27 LICs. Primary qualitative, quantitative and mixed-methods evidence was included, as well as original analysis of secondary data. The Joanna Briggs Institute's critical appraisal tool was used to assess the quality of the studies. Relevant evidence was extracted and analysed using an adapted UHC framework. We identified 34 papers documenting how most basic health care services are already provided through the private sector in countries such as Uganda, Afghanistan and Somalia. A substantial proportion of primary care, mother, child and malaria services are available through non-public providers across all 27 LICs. Evidence exists that while formal private providers mostly operate in well-served urban settings, informal and not-for-profit ones cater for underserved rural and urban areas. Nonetheless, there is evidence that the quality of the services by informal providers is suboptimal. A few studies suggested that the private sector fails to advance financial protection against ill-health, as costs are higher than in public facilities and services are paid out of pocket. We conclude that despite their shortcomings, working with informal private providers to increase quality and financing of their services may be key to realizing UHC in LICs.

Antimalarial procurement in private-sector pharmaceutical outlets: decision-making complexities and implications for medicine quality in Tanzania

Poor-quality medicines are a major threat to healthcare provision in low-income countries. The problem exacerbates disease vulnerabilities of already disadvantaged populations including children, women, and the elderly. However, while the higher-level structural drivers of this problem are well established, little is known about decision-making lower down pharmaceutical supply chains, and whether this might produce vulnerabilities for medicine quality. We conducted a mixed-methods study to explore retailer-supplier interactions and decision-making dynamics for antimalarial medicines in three regions of Tanzania: Tabora, Dodoma and Mbeya. A survey questionnaire was administered to 118 small scale-and mid-range retailers in urban and rural districts of the regions. We then conducted 12 in-depth interviews with staff and owners of medicine outlets in 2 districts of Tabora region to explore further the decision-making dynamics. Results show that private-sector retailers are driven first and foremost by business and economic practicalities when choosing a medicine supplier, prioritising low purchase price, free delivery, and availability of credit. Many also rely on suppliers with whom they have personal connections, developed either within or outside the business context. Medicine quality comes far lower down the list of priorities. These findings are perhaps not surprising in a context where businesses serving low-income customers are operating on very small margins. However, when price and personal connection eclipse any other considerations, there is a risk that poor-quality medicines may find their way into supply chains, especially in countries where regulatory capacity is limited, and pharmaceutical supply chains are complex and opaque.

Antimalarial stocking decisions among medicine retailers in Ghana: implications for quality management and control of malaria

Global health efforts such as malarial control require efficient pharmaceutical supply chains to ensure effective delivery of quality-assured medicines to those who need them. However, very little is currently known about decision-making processes within antimalarial supply chains and potential vulnerabilities to substandard and falsified medicines. Addressing this gap, we report on a study that investigated decision-making around the stocking of antimalarial products among private-sector medicine retailers in Ghana. Licensed retail pharmacies and over-the-counter (OTC) medicine retail outlets were sampled across six regions of Ghana using a two-stage stratified sampling procedure, with antimalarial medicines categorised as 'expensive,' 'mid-range,' and 'cheaper,' relative to other products in the shop. Retailers were asked about their motivations for choosing to stock particular products over others. The reasons were grouped into three categories: financial, reputation/experience and professional recommendation. Reputation/experience (76%, 95% CI 72.0% to 80.7%) were the drivers of antimalarial stocking decisions, followed by financial reasons (53.2%, 95% CI 48.1% to 58.3%) and recommendation by certified health professionals (24.7%, 95% CI 20.3% to 29.1%). Financial considerations were particularly influential in stocking decisions of cheaper medicines. Moreover, pharmacies and OTCs without a qualified pharmacist were significantly more likely to indicate financial reasons as a motivation for stocking decisions. No significant differences in stocking decisions were found by geographical location (zone and urban/rural) or outlet (pharmacy/OTC). These findings have implications for the management of antimalarial quality across supply chains in Ghana, with potentially important consequences for malaria control, particularly in lower-income areas where people rely on low-cost medication.

Health, Economic, and Social Impacts of Substandard and Falsified Medicines in Low- and Middle-Income Countries: A Systematic Review of Methodological Approaches

Little is known about the adverse health, economic, and social impacts of substandard and falsified medicines (SFMs). This systematic review aimed to identify the methods used in studies to measure the impact of SFMs in low- and middle-income countries (LMICs), summarize their findings, and identify gaps in the reviewed literature. A search of eight databases for published papers, and a manual search of references in the relevant literature were conducted using synonyms of SFMs and LMICs. Studies in the English language that estimated the health, social, or economic impacts of SFMs in LMICs published before June 17, 2022 were considered eligible. Search results generated 1,078 articles, and 11 studies were included after screening and quality assessment. All included studies focused on countries in sub-Saharan Africa. Six studies used the Substandard and Falsified Antimalarials Research Impact model to estimate the impact of SFMs. This model is an important contribution. However, it is technically challenging and data demanding, which poses challenges to its adoption by national academics and policymakers alike. The included studies estimate that substandard and falsified antimalarial medicines can account from 10% to ∼40% of total annual malaria costs, and SFMs affect rural and poor populations disproportionately. Evidence on the impact of SFMs is limited in general and nonexistent regarding social outcomes. Further research needs to focus on practical methods that can serve local authorities without major investments in terms of technical capacity and data collection.

Impact of the COVID-19 pandemic on the quality of medical products in Zimbabwe: a qualitative study based on key informant interviews with health system stakeholders

OBJECTIVE

To explore the impact of the Coronavirus disease 2019 (COVID-19) pandemic on the quality of medical products in Zimbabwe, including market risks for substandard and falsified products and impacts on quality assurance activities.

DESIGN

Qualitative study based on in-depth key informant interviews.

SETTING

Health system stakeholders across the medical product supply chain in Zimbabwe.

PARTICIPANTS

36 key informants were interviewed between April and June 2021.

RESULTS

We found that the COVID-19 pandemic disrupted quality assurance and regulatory activities of medical products in Zimbabwe, resulted in observations of poor-quality personal protective equipment (PPE) and other COVID-19-related products and led to increased risks to quality. Risks to quality due to COVID-19-related disruptions included increased layers of agents in the supply chain and an influx of non-traditional suppliers. COVID-19-related movement restrictions reduced access to health facilities and thus may have increased the usage of the informal market where smuggled and unregistered medical products are sold with less oversight by the regulator. Most reports of poor-quality medical products were for PPE, such as masks and infrared thermometers, used for the COVID-19 response. Besides these reports, many participants stated that the quality of essential medicines in the formal sector, not related to COVID-19, had largely been maintained during the pandemic due to the regulator's stringent quality assurance process. Incentives for suppliers to maintain quality to retain large donor-funded contracts, and the need for local wholesalers and distributors to comply with quality-related aspects of distribution agreements with global manufacturers of brand-name medical products, mitigated threats to quality.

CONCLUSIONS

The COVID-19 pandemic presented opportunities and market risks for circulation of substandard and falsified medical products in Zimbabwe. There is a need for policymakers to invest in measures to safeguard the quality of medical products during emergencies and to build resiliency against future supply chain shocks.

Insights from a qualitative study of the procurement and manufacture of active pharmaceutical ingredients in India

Medicine supply systems are a crucial part of health systems and access to effective essential medicines is a key pillar of Universal Health Coverage. However, efforts to expand access are compromised by the proliferation of substandard and falsified medicines. The vast majority of research to date on medicine supply chains has focused on the formulation and distribution of the finished product, overlooking the crucial steps of Active Pharmaceutical Ingredient production that precede this. In this paper, we draw on qualitative interviews with manufacturers and regulators in India to take a 'deep dive' into these understudied parts of medicine supply chains.

Revisiting the blind spot of substandard and fake drugs as drivers of antimicrobial resistance in LMICs

One of the most significant risks to public health is ongoing antimicrobial resistance (AMR). Substandard and fraudulent medications, particularly in low- and middle-income countries (LMICs), are thought to have a role in the genesis and spread of AMR. There are numerous reports concerning the availability of subpar pharmaceuticals in developing countries, with no scientific evidence as to what exactly is included in some of the prescriptions supplied there. These counterfeit and inferior pharmaceuticals are a financial burden of up to US$200 billion, causing thousands of patient deaths, endangering both individual and public health,and undermining patient trust in the healthcare system. Poor quality and counterfeit antibiotics are often disregarded as possible causes of AMR in AMR studies. Therefore, we examined the issue of fake drugs in LMICs and its possible links to the emergence and spread of AMR.

Why falsified medicines reach patients: an analysis of political and economic factors in Romania

INTRODUCTION

To protect patients against falsified medicines, countries around the world implement stringent regulations. Despite efforts to protect supply chains in the European Union (EU), authorities continue to find falsified medicine. We studied how in Romania, one of the poorest EU countries, political and economic factors influence the risk of patients being exposed to falsified medicines.

METHODS

For this case study, we reviewed 131 documents and interviewed 22 purposively selected key informants.

RESULTS

In Romania, several politically and economically motivated policies have led to persistent medicine shortages. Following the 2007 accession to the EU, fierce competition led to a decline in domestic medicine production. Soon after, the government introduced a tax on reimbursed medicines to support the national health budget. Prior to the 2015 elections, medicine prices were abruptly lowered to provide voters with the cheapest medicine in Europe. The low prices incentivised traders to buy medicines in Romania and sell them elsewhere in the EU. The high taxes and low prices led manufacturers to withdraw medicines from the market and impose product quotas to limit parallel trading. The accumulated effect of these market responses translated into persistent shortages of essential medicine, which have pushed patients and health professionals to unregulated markets with a high risk of exposure to falsified medicine.

CONCLUSION

Strategies against falsified medicine with a narrow focus on safeguarding quality in the regulated supply are insufficient. To protect patients, governments must also ensure that patients have access to affordable medicines, as shortages provide an opportunity for those selling fake products.

Relative Risk Assessment for Substandard Antibiotics Along the Manufacturing and Supply Chain: A Proof-of-Concept Study

BACKGROUND

Ensuring good quality of antibiotics is essential for desired health outcomes. Risk assessment of products for quality issues arising along the manufacturing and supply chain can thus have an important role in surveillance and management of interventions designed to reduce the burden of substandard antibiotics. Demonstrated and validated risk assessments are currently limited.

OBJECTIVES

The objective of this study was to investigate whether a comparative risk assessment framework, which adapts the WHO criteria for estimating risks for quality issues posed by individual medicines, is applicable and can identify antibiotics with a higher relative risk of substandard prevalence.

METHODS

For a proof-of-concept study, a set of antibiotics from the WHO essential medicines list was selected. Quantitative and qualitative data were extracted for each risk assessment criteria pertaining to severity and probability. A final risk matrix was then compared to field data for validation.

RESULTS

Antibiotic products were classified by relative risk. Of all the antibiotic products assessed (n = 28), 32% were categorized as highest risk, 46% as high risk, 18% as medium risk, and 4% as lowest risk. The comparison of the risk scores and incidence of quality failure from the USP Medicines Quality Database showed significant correlation.

CONCLUSION

The framework and extracted data sets appear applicable to determine relative risk for substandard antibiotics. Results of the risk matrix may be valuable for guiding pharmacovigilance, surveillance strategies, standardizing risk-based approaches, and mitigation efforts. Refinement with increased data availability may improve results.

Stakeholder perspectives on the demand and supply factors driving substandard and falsified blood pressure lowering medications in Nigeria: a qualitative study

OBJECTIVES

Although substandard and falsified (SF) blood pressure (BP) lowering medications are a global problem, qualitative research exploring factors driving this in Nigeria has not been reported. This study provides information on factors driving demand for and supply of low-quality BP lowering medications in Nigeria and potential strategies to address these factors.

METHODS

This was a cross-sectional qualitative study. Between August 2020 and September 2020, we conducted 11 in-depth interviews and 7 focus group discussions with administrators of health facilities, major manufacturers and distributors of BP lowering medications, pharmacists, drug regulators, patients and primary care physicians purposively sampled from the Federal Capital Territory, Nigeria. Data were analysed using directed content analysis, with the aid of Dedoose.

RESULTS

We found that demand for SF BP lowering medications in Nigeria was driven by high out-of-pocket expenditure and stockouts of quality-assured BP lowering medications. Supply of low-quality BP lowering medications was driven by limited in-country manufacturing capacity, non-adherence to good manufacturing and distribution practices, under-resourced drug regulatory systems, ineffective healthcare facility operations, poor distribution practices, limited number of trained pharmacists and the COVID-19 pandemic which led to stockouts. Central medicine store procurement procedures, active pharmaceutical ingredient quality check and availability of trained pharmacists were existing strategies perceived to lower the risk of supply and demand of SF BP lowering medications.

CONCLUSION

Our findings suggest that demand for and supply of SF BP lowering medications in Nigeria are driven by multi-level, interrelated factors. Multi-pronged strategies need to target stakeholders and systems involved in drug production, distribution, prescription, consumption, regulation and pricing.

Environmental DNA as an innovative technique to identify the origins of falsified antimalarial tablets-a pilot study of the pharmabiome

Falsified medicines are a major threat to global health. Antimalarial drugs have been particularly targeted by criminals. As DNA analysis has revolutionized forensic criminology, we hypothesized that these techniques could also be used to investigate the origins of falsified medicines. Medicines may contain diverse adventitious biological contamination, and the sealed nature of blister-packages may capture and preserve genetic signals from the manufacturing processes allowing identification of production source(s). We conducted a blinded pilot study to determine if such environmental DNA (eDNA) could be detected in eleven samples of falsified and genuine artesunate antimalarial tablets, collected in SE Asia, which could be indicative of origin. Massively Parallel Sequencing (MPS) was used to characterize microbial and eukaryote diversity. Two mitochondrial DNA analysis approaches were explored to detect the presence of human DNA. Trace eDNA from these low biomass samples demonstrated sample specific signals using two target markers. Significant differences in bacterial and eukaryote DNA community structures were observed between genuine and falsified tablets and between different packaging types of falsified artesunate. Human DNA, which was indicative of likely east Asian ancestry, was found in falsified tablets. This pilot study of the 'pharmabiome' shows the potential of environmental DNA as a powerful forensic tool to assist with the identification of the environments, and hence location and timing, of the source and manufacture of falsified medicines, establish links between seizures and complement existing tools to build a more complete picture of criminal trade routes. The finding of human DNA in tablets raises important ethical issues that need to be addressed.

Substandard and falsified antibiotics: neglected drivers of antimicrobial resistance?

OBJECTIVES

Antimicrobial resistance (AMR) is a significant global health threat with substandard and falsified (SF) antibiotics being neglected contributing factors. With their relationships poorly understood, more research is needed in order to determine how interventions to reduce SF antibiotics should be ranked as priorities in national AMR action plans. We assessed the evidence available on the global prevalence of SF antibiotics, examined the quality of the evidence and discussed public health impact.

MATERIALS/METHODS

We searched PubMed, Embase, Google and Google Scholar for publications on antibiotic quality up to 31 December 2020. Publications reporting on the prevalence of SF antibiotics were evaluated for quantitative analysis and assessed using the Medicines Quality Assessment Reporting Guidelines.

RESULTS

Of the 10 137 screened publications, 648 were relevant to antibiotic quality. One hundred and six (16.4%) surveys, published between 1992 and 2020 and conducted mainly in low-income and middle-income countries (LMICs) (89.9% (480/534) of the data points), qualified for quantitative analysis. The total number of samples tested for quality in prevalence surveys was 13 555, with a median (Q1-Q3) number of samples per survey of 47 (21-135). Of the 13 555 samples, 2357 (17.4%) failed at least one quality test and the median failure frequency (FF) per survey was 19.6% (7.6%-35.0%). Amoxicillin, sulfamethoxazole-trimethoprim and ciprofloxacin were the most surveyed antibiotics, with FF of 16.1% (355/2208), 26.2% (329/1255) and 10.4% (366/3511), respectively. We identified no SF survey data for antibiotics in the WHO 'Reserve' group. The mean Medicine Quality Assessment Reporting Guidelines score was 11 (95% CI 10.1 to 12.2) out of 26.

CONCLUSIONS

SF antibiotics are widely spread with higher prevalence in LMICs. The quality of the evidence is poor, and these data are not generalisable that 17.4% of global antibiotic supply is SF. However, the evidence we have suggests that interventions to enhance regulatory, purchasing and financial mechanisms to improve the global antibiotic supply are needed.

Trends in counterfeit drugs and pharmaceuticals before and during COVID-19 pandemic

Counterfeit, fake, adulterated or falsified drugs and pharmaceuticals, could be branded or generic drugs, excipients and active substances (in drugs and vaccines), medical supplies and devices, etc, intended to pass as the original. Counterfeits are always inferior in terms of quality, safety and efficacy compared to the original pharmaceuticals, and subsequently, they pose an unpredictable risk to public health and lead to loss of confidence in medicines, healthcare providers, and health systems. In the decades before the outbreak of the COVID-19 pandemic, a constant trend of increased trafficking was reported. However, the pandemic created a combination of public health emergency, economic distress, and misinformation-driven panic that made problematic the access and supply of high quality essential medicines and health products, and pushed consumers and vendors even more towards counterfeit pharmaceuticals. This contribution aims to review the trends in counterfeit drugs and pharmaceuticals trafficking, the health impact of their use, as well as, measures and actions implemented to restrict their proliferation, before and during COVID-19 pandemic; the relative recommendations, the expressed perspectives and the existing limitations are thoroughly discussed.

Smartphone as a Portable Detector for Thin-Layer Chromatographic Determination of Some Gastrointestinal Tract Drugs

Thin-layer chromatography (TLC) is an effective and simple technique for screening, evaluating, and quantifying low-quality and counterfeit pharmaceutical products. Smartphones have recently been used as accessible, cheap, and portable detectors that can replace more complicated analytical detectors. In this work, we have developed a simple and sensitive TLC method utilizing a smartphone charged-coupled device (CCD) camera not only to verify and quantify some gastrointestinal tract drugs, namely, loperamide hydrochloride (LOP) and bisacodyl (BIS), but also to detect acetaminophen (ACT) as a counterfeit drug. Both drugs (LOP and BIS) were chromatographed separately on a silica gel 60 F₂₅₄ plate as a stationary phase under previously reported chromatographic conditions, using ethyl acetate:methanol:ammonium hydroxide (24:3:1, by volume) and ethyl acetate:methanol:glacial acetic acid (85:10:5, by volume) as developing systems to determine LOP and BIS, respectively. Universal stains, namely, iodine vapors and vanillin, were used to visualize the spots on the TLC plates to get a visual image using the smartphone camera and a spotlight as an illumination source with no need for a UV illumination source. The spot intensity was calculated using a commercially available smartphone application for quantitative analysis of the studied drugs utilizing ″acetaminophen″ as an example of a counterfeit substance. R_f values were calculated using the recorded images and found to be 0.77, 0.79, and 0.74 for LOP, BIS, and ACT, respectively, providing drug identity. Linear calibration curves using the smartphone-TLC method were obtained between the luminance and the corresponding concentrations over the ranges of 2.00-10.00 μg/mL and 1.00-10.00 μg/mL with limits of detection of 0.57 and 0.10 μg/mL for LOP and BIS, respectively. The suggested method was validated according to the International Conference of Harmonization (ICH) guidelines. The method was then successfully applied for the qualitative and quantitative determination of LOP or BIS as an example for gastrointestinal tract drugs in pure form and in their pharmaceutical dosage formulations. The proposed method is considered as a perfect alternative to traditional reported densitometric methods due to its simplicity, easy application, and inexpensiveness. No previously reported methods utilizing smartphones have been published for the determination of the studied drugs. The developed approach is considered the first TLC method using smartphones for the determination of some gastrointestinal tract drugs in their pure form and in pharmaceutical formulations.

Characterizing Medicine Quality by Active Pharmaceutical Ingredient Levels: A Systematic Review and Meta-Analysis across Low- and Middle-Income Countries

Substandard and falsified medicines are often reported jointly, making it difficult to recognize variations in medicine quality. This study characterized medicine quality based on active pharmaceutical ingredient (API) amounts reported among substandard and falsified essential medicines in low- and middle-income countries (LMICs). A systematic review and meta-analysis was conducted using PubMed, supplemented by results from a previous systematic review, and the Medicine Quality Scientific Literature Surveyor. Study quality was assessed using the Medicine Quality Assessment Reporting Guidelines (MEDQUARG). Random-effects models were used to estimate the prevalence of medicines with < 50% API. Among 95,520 medicine samples from 130 studies, 12.4% (95% confidence interval [CI]: 10.2-14.6%) of essential medicines tested in LMICs were considered substandard or falsified, having failed at least one type of quality analysis. We identified 99 studies that reported API content, where 1.8% (95% CI: 0.8-2.8%) of samples reported containing < 50% of stated API. Among all failed samples (N = 9,724), 25.9% (95% CI: 19.3-32.6%) reported having < 80% API. Nearly one in seven (13.8%, 95% CI: 9.0-18.6%) failed samples were likely to be falsified based on reported API amounts of < 50%, whereas the remaining six of seven samples were likely to be substandard. Furthermore, 12.5% (95% CI: 7.7-17.3%) of failed samples reported finding 0% API. Many studies did not present a breakdown of actual API amount of each tested sample. We offer suggested improved guidelines for reporting poor-quality medicines. Consistent data on substandard and falsified medicines and medicine-specific tailored interventions are needed to ensure medicine quality throughout the supply chain.

A systematic review of pooled procurement of medicines and vaccines: identifying elements of success

INTRODUCTION

Pooled procurement of health commodities has increasingly been promoted as a solution to reduce prices, increase availability, and achieve more efficient procurement processes. However, little is known about what is required to implement pooled procurement mechanisms successfully and how they function under specific circumstances. Therefore, the aim of this systematic review is to synthesize empirically grounded insights by identifying the elements that are essential for setting up and operating pooled procurement mechanisms of medicines and vaccines.

METHODS

Our review was based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We searched PubMed, Scopus and Web of Science for empirical studies on pooled procurement of medicines and vaccines using various search terms. Publications were assessed based on predetermined eligibility criteria.

RESULTS

Our initial search yielded 1596 publications, of which 44 were eventually included in our review. Most of the included articles focused on pooled procurement mechanisms that operated on a sub-national level (43%), procured a variety of products (38%), and were set up with the goal to contain costs (64%). The review identified several elements that are essential for pooled procurement mechanisms to function. We organized these elements around three key actors in the mechanism: buyers, the pooled procurement organization, and suppliers. To participate in pooled procurement, buyers need a sufficient level of technical capacity, financial capacity and compatible laws and regulations. To carry out pooled procurement, the pooled procurement organization needs sufficient financial capacity, technical capacity, and independent operations. To supply the mechanism with health commodities, suppliers need sufficient incentives, such as a sufficient market size and a prompt payment mechanism.

CONCLUSION

Pooled procurement mechanisms are very diverse. They differ in characteristics and organizational structures and are set up to achieve a variety of goals. While certain essential elements are more likely to increase successful implementation and functioning of pooled procurement mechanisms, the organizational structure must be aligned with the goals of the mechanism, and adapted to the local contextual environment.

Substandard and falsified medical products: bibliometric analysis and mapping of scientific research

Objective

Substandard and falsified (SF) medical products are a global public health threat. The presence and spread of SF drugs negatively affect (1) patients’ safety and health outcomes, (2) national economy, (3) public trust in the healthcare system, and (4) the international fight against serious health challenges such as malaria and antimicrobial resistance. The objective of the current study was to investigate and provide a snapshot analysis of the evolution and developmental patterns of global research publications on SF products.

Methods

A bibliometric approach was adopted using terms such as fake, falsified, counterfeit, substandard, and others. No language restriction was made. The study period was from 1900 up to 2020. The search strategy was validated and implemented using Scopus database.

Results

The search strategy retrieved 978 documents authored by 2861 researchers from 100 different countries and published in 421 different journals. The retrieved documents received 11,237 citations (11.5 citations per document) with an H-index of 53. The 978 documents retrieved from Scopus were published from 1961 to 2020, giving an average of 16.6 publications per year. The present study indicated that research on SF medical products: (a) has experienced a steep growth from 2001 to 2012 followed by a steady-state growth; (b) was disseminated in a wide range of journals, mainly in the fields of the pharmaceutical industry, analytical chemistry, public health, infectious diseases, and internal medicine; (c) was published by scholars with diverse and distant geographical backgrounds; (d) was mainly produced in the United States, United Kingdom, and Germany; (d) has fragmented research networks and a limited number of researchers per network; (e) has limited cross-country collaboration except for that between the US and the UK in one hand and countries in the Mekong region in the other hand; (f) emphasized on medications related to malaria and sexual stimulants; and (g) received relatively inadequate funding.

Conclusions

Research on SF medical products is important and should remain a priority to ensure good quality of medications. Research activity in the field needs to be encouraged in world regions such as Africa and the Middle East where drug regulations are unsatisfactory and cross-border trade of illegal medications is common.

Substandard and Falsified Medicines: Proposed Methods for Case Finding and Sentinel Surveillance

The World Health Organization and others warn that substandard and falsified medicines harm health and waste money, especially in low- and middle-income countries. However, no country has measured the market-wide extent of the problem, and no standardized methods exist to estimate the prevalence of either substandard or falsified medicines. This is, in part, because the task seems overwhelming; medicine markets are huge and diverse, and testing medicines is expensive. Many countries do operate some form of postmarket surveillance of medicine, but their methods and goals differ. There is currently no clear guidance on which surveillance method is most appropriate to meet specific public health goals. In this viewpoint, we aimed to discuss the utility of both case finding and risk-based sentinel surveillance for substandard and falsified medicines, linking each to specific public health goals. We posit that choosing the system most appropriate to the goal, as well as implementing it with a clear understanding of the factors driving the production and sale of substandard and falsified medicines, will allow for surveillance resources to be concentrated most efficiently. We adapted principles used for disease outbreak responses to suggest a case-finding system that uses secondary data to flag poor-quality medicines, proposing risk-based indicators that differ for substandard and falsified medicines. This system potentially offers a cost-effective way of identifying “cases” for market withdrawal, enhanced oversight, or another immediate response. We further proposed a risk-based sentinel surveillance system that concentrates resources on measuring the prevalence of substandard and falsified medicines in the risk clusters where they are most likely to be found. The sentinel surveillance system provides base data for a transparent, spreadsheet-based model for estimating the national prevalence of substandard and falsified medicines. The methods we proposed are based on ongoing work in Indonesia, a large and diverse middle-income country currently aiming to achieve universal health coverage. Both the case finding and the sentinel surveillance system are designed to be adaptable to other resource-constrained settings.

Implementing pharmaceutical track-and-trace systems: a realist review

INTRODUCTION

One way to prevent falsified medical products from entering the regulated pharmaceutical supply chain is to implement a pharmaceutical track-and-trace system (PTTS). Such systems in the most extensive versions generally mandate a scan at every point of contact with the medical product: from the point of entry to dispensation. There have been several attempts to implement such systems; for example, a 'full' PTTS in Turkey and the more pared-down version offered by the European Union's Falsified Medicines Directive and Delegated Act. This study aims to identify facilitators and barriers to implementing (elements of) a PTTS, with the Turkish system used as a benchmark.

METHODS

We conducted a 'realist' review, which synthesises literature and aims to establish how a specific technology works, for whom, under which circumstances. We searched Embase, Medline Ovid, Web of Science, Cochrane Central and Google Scholar databases, yielding 2,790 scholarly articles. We selected 21 for review.

RESULTS

Implementation of PTTS elements has been attempted in different compositions in several primarily high-income and middle-income countries. Factors that affected implementation included stakeholders like the government and supply chain actors, the coordination between them, and their awareness, knowledge, and skills, as well as regulation and legislation, monetary investments, and technical and digital requirements.

CONCLUSION

The interplay between contextual factors is crucial for successful PTTS implementation. Specifically, the findings indicate that aligning the incentives for all actors and allowing for adjustments in a continuous implementation process will likely facilitate implementation.

Monitoring, reporting and regulating medicine quality: tensions between theory and practice in Tanzania

In 2012, the WHO launched its Global Surveillance and Monitoring System (GSMS) for substandard and falsified medicines, with the aim of improving the quality of reporting and using the data to inform post-market surveillance and build regulatory capacity. However, from a regulatory governance perspective, its effectiveness depends on the willingness and ability of actors ‘on the ground’ to identify, report and investigate possible infringements and to enforce penalties. This paper presents findings from 27 interviews with representatives of agencies charged with regulating pharmaceutical markets and 4 interviews with pharmaceutical industry representatives in Tanzania. Their experiences provide important insights into how the theorised mechanism between reporting and a reduction in undesirable behaviours can play out in a low-income context, revealing hidden assumptions about regulator behaviour and motivations. A combination of chronic under-resourcing, information gaps and enforcement challenges conspires to limit the efforts of local regulators to achieve the GSMS goals, shedding new light on the relationship between apparent ‘misconduct’ and structural constraints.

Challenges in maintaining medicine quality while aiming for universal health coverage: a qualitative analysis from Indonesia

Introduction

Indonesia, the world’s fourth most populous nation, is close to achieving universal health coverage (UHC). A widely-publicised falsified vaccine case in 2016, coupled with a significant financial deficit in the national insurance system, has contributed to concern that the rapid scale-up of UHC might undermine medicine quality. We investigated the political and economic factors that drive production and trade of poor-quality medicines in Indonesia.

Methods

We reviewed academic publications, government regulations, technical agency documents and news reports to develop a semi-structured questionnaire. We interviewed healthcare providers, policy-makers, medicine regulators, pharmaceutical manufacturers, patients and academics (n=31). We included those with in-depth knowledge about the falsified vaccine case or the pharmaceutical business, medicine regulation, prescribing practice and the implementation of UHC. We coded data using NVivo software and analysed by constant comparative method.

Results

The scale-up of UHC has cut revenues for physicians and pharmaceutical manufacturers. In the vaccine case, free, quality-assured vaccines were available but some physicians, seeking extra revenue, promoted expensive alternatives. Taking advantage of poor governance in private hospitals, they purchased cut-price ‘vaccines’ from freelance salespeople.

A single-winner public procurement system which does not explicitly consider quality has slashed the price paid for covered medicines. Trade, industrial and religious policies simultaneously increased production costs, pressuring profit margins for manufacturers and distributors. They reacted by cutting costs (potentially threatening quality) or by market withdrawal (leading to shortages which provide a market for falsifiers). Shortages and physician-promoted irrational demand push patients to buy medicines in unregulated channels, increasing exposure to falsified medicines.

Conclusion

Market factors, including political pressure to reduce medicine prices and healthcare provider incentives, can drive markets for substandard and falsified medicines. To protect progress towards UHC, policy-makers must consider the potential impact on medicine quality when formulating rules governing health financing, procurement, taxation and industry.

Elusive quality: the challenges and ethical dilemmas faced by international non-governmental organisations in sourcing quality assured medical products

Although medical products that are of sound quality are fundamental to the delivery of healthcare, so too is their availability, affordability, accessibility and acceptability. However, achieving all of these aims consistently and simultaneously may be unfeasible due to a host of barriers—no matter the country. If uncertainty, constraints and conflicting priorities also threaten their delivery, not only does the situation becomes yet more challenging, the morally just course of action becomes yet more opaque. While global health organisations, supply chains and projects are heterogenous, international non-governmental organisations (iNGOs) responding to humanitarian crises or delivering development assistance in low-income and middle-income countries are undoubtedly prone to this issue. In a novel framing of the problem of substandard and falsified medicines, this article explores some ethical dilemmas that, directly or indirectly, could result in the quality of medical products in iNGO health projects to be compromised. Drawing on a broad literature base and years of experience as a senior humanitarian pharmacist, the author reflects on the barriers, culture and system that contributes to the existence and persistence of substandard and falsified medical products in global assistance projects. The paper offers an in-depth examination of pressures that may arise in four key areas (capacity, supply chain, bureaucracy and quality assurance) and postulates on the myriad ways in which this may alter the attitudes, behaviours and decision-making of iNGOs in a manner that disincentivises the prioritisation of medical product quality. This paper does not seek to excoriate the aid sector, but rather to lend a new perspective: that such predicaments are overlooked, real-world ethical dilemmas in urgent need of greater openness, research, debate and guidance, for the benefit of moral decision-making and patient care.

TLC-smartphone in antibiotics determination and low-quality pharmaceuticals detection

Thin layer chromatography (TLC) is a powerful and simple technique for screening and quantifying low quality and counterfeit pharmaceutical products. The detection methods used to detect and quantify separate analytes in TLC ranges from the densitometric method to mass spectrometric or Raman spectroscopic methods. This work describes the development and optimization of a simple and sensitive TLC method utilizing a smartphone CCD camera for verification of both identity and quantity of antibiotics in dosage form, namely ofloxacin and ornidazole. Mixtures of ofloxacin and ornidazole were chromatographed on a silica gel 60 F₂₅₄ plate as a stationary phase. The optimized mobile phase is n-butanol : methanol : ammonia (8 : 1 : 1.5 by volume). Iodine vapor has been used as a "universal stain" to visualize the spots on the TLC plates in order to obtain a visual image using the smartphone camera and a desk lamp as an illumination source, thus eliminating the need for a UV illumination source. The recorded images were processed to calculate the R _f values (R _f values for ofloxacin and ornidazole were 0.12 and 0.76, respectively) which provide identity of the drugs while spot intensity was calculated using a commercially available smartphone app and employed for quantitative analysis of the antibiotics and "acetaminophen" as an example of a counterfeit substance. The smartphone TLC method yielded a linearity of ofloxacin and ornidazole in the range of 12.5-62.5 μg/band and 500-1000 μg/band, respectively. The limit of detection was found to be 1.6 μg/spot for ofloxacin and 97.8 μg/spot for ornidazole. The proposed method was compared with the bench top densitometric method for verification using a Camag TLC Scanner 3, the spot areas were scanned at 320 nm. The R _f value of ofloxacin and ornidazole was calculated to be 0.12 and 0.76, respectively. The densitometric method yielded a linearity of ofloxacin and ornidazole in the range of 5-40 μg/band and 5-50 μg/band, respectively. The limit of detection was found to be 0.8 μg/spot for ofloxacin and 1.1 μg/spot for ornidazole. The proposed method has been successfully applied for the determination of ofloxacin and ornidazole present in more than one pharmaceutical dosage form and was comparable to the densitometric method.

Clarification of the internal structure and factors of poor dissolution of substandard roxithromycin tablets by near-infrared chemical imaging

The spread of substandard and falsified medicines has become a global problem, especially in low- and middle-income countries (LMICs). Previously, we found that some tablets containing the same active ingredient had large differences in their dissolution even though their contents were comparable. In this study, we investigated the poor dissolution of roxithromycin tablets using near-infrared chemical imaging (NIR-CI) to visualize the internal tablet structure. Roxithromycin tablets collected in LMICs and the pioneer product Rulid® as a reference were cut to a flat surface for analysis. NIR spectral data were normalized, and a principal component analysis was performed to create a tablet internal structure image. For Rulid®, the differences between the spectra with high and low scores were small, and well-defined aggregation of ingredients was not observed. However, large differences in the scores were found for roxithromycin tablets manufactured in some LMICs, and non-uniformity of ingredient distribution and aggregation were observed. Additionally, some pharmaceutical excipients, such as starch or magnesium stearate, were found in certain aggregates by comparing NIR spectra. The NIR-CI results showed some excipients existed as large aggregates, which indicated that the ingredients were not evenly mixed in the roxithromycin tablet, and this contributed to its poor dissolution.

Addressing budget reduction and reallocation on health-related resources during COVID-19 pandemic in malaria-endemic countries

The global COVID-19 pandemic has been affecting the maintenance of various disease control programmes, including malaria. In some malaria-endemic countries, funding and personnel reallocations were executed from malaria control programmes to support COVID-19 response efforts, resulting mainly in interruptions of disease control activities and reduced capabilities of health system. While it is principal to drive national budget rearrangements during the pandemic, the long-standing malaria control programmes should not be left behind in order to sustain the achievements from the previous years. With different levels of intensity, many countries have been struggling to improve the health system resilience and to mitigate the unavoidable stagnation of malaria control programmes. Current opinion emphasized the impacts of budget reprioritization on malaria-related resources during COVID-19 pandemic in malaria endemic countries in Africa and Southeast Asia, and feasible attempts that can be taken to lessen these impacts.

What are the volume and budget needs to provide chemotherapy to all children with acute lymphoblastic leukaemia in Thailand? Development and application of an estimation tool

OBJECTIVE

Insufficient access to anticancer medicines may contribute to the wide survival differences of children with cancers across the globe. We developed a tool to estimate the volume of medicines and budget requirements to provide chemotherapy to children with acute lymphoblastic leukaemia (ALL).

DESIGN

Development and application of an estimation tool.

SETTING

Paediatric oncology hospital departments in Thailand.

PARTICIPANTS

318 children aged 0-14 years diagnosed with ALL and 215 children with undiagnosed ALL.

INTERVENTIONS

Estimates of volume and budget requirements for administering a full course of chemotherapy for ALL and a further course for children who relapse, according to National Treatment Guidelines.

PRIMARY AND SECONDARY OUTCOME MEASURES

Primary outcome measures were the volume (mg) and cost (US$) of medicines needed to treat children with ALL. For medicines whose main indication is paediatric ALL (asparaginase and 6-mercaptopurine), we estimated the difference between volume needed and actual sales in 2017 (secondary outcome).

RESULTS

Ten anticancer medicines and four chemoprotective agents are needed for the treatment of paediatric ALL according to the Thai treatment guidelines. Of these 14 medicines, 13 are included in the WHO essential medicines list for children. All are available as generics. We estimated that essential chemotherapy and chemoprotective agents to treat all children diagnosed with ALL in Thailand in 2017 would cost US$ 814 952 (US$ 1 365 422 for diagnosed and undiagnosed children), which corresponds to 0.005% (0.008%) of the country's total health expenditure. The volumes of asparaginase and 6-mercaptopurine available on the Thai market in 2017 were more than sufficient (2.3 and 1.5 times the amounts needed, respectively) to treat all children diagnosed with ALL.

CONCLUSIONS

Procuring sufficient quantities of essential medicines to treat children with ALL requires relatively modest resources. Medicine cost should not be a major barrier to ALL treatment in similar settings.

How Do We Combat Bogus Medicines in the Age of the COVID-19 Pandemic?

The COVID-19 pandemic has brought concurrent challenges. The increased incidence of fake and falsified product distribution is one of these problems with tremendous impact, especially in low- and middle-income countries. Up to a tenth of medicines including antibiotics and antimalarial drugs in the African market are considered falsified. Pandemics make this worse by creating an ecosystem of confusion, distraction, and vulnerability stemming from the pandemic as health systems become more stressed and the workload of individuals increased. These environments create opportunities for substandard and falsified medicines to be more easily introduced into the marketplace by unscrupulous operators. In this work we discuss some of the challenges with fake or falsified product distribution in the context of COVID-19 and proposed strategies to best manage this problem.

What Makes a National Pharmaceutical Track and Trace System Succeed? Lessons From Turkey

BACKGROUND

Track and trace systems are increasingly being implemented as a technological solution to secure pharmaceutical supply chains. Turkey was the first country to implement a full pharmaceutical track and trace system throughout the entire regulated domestic supply chain. This article explores the emergence and functioning of this system and the consequences for substandard and falsified medicine with a focus on the underlying political and economic factors.

METHODS

This study uses an explanatory case study approach that combined interviews with purposefully selected key informants and document analyses.

RESULTS

The main drivers for implementing the pharmaceutical track and trace system in Turkey centered on the elimination of reimbursement fraud and the prevention of falsified medicine in the regulated supply chain. Although stakeholders experienced both physical and software-related problems in implementation, the alignment of incentives of all stakeholders with the power of the state, along with leeway for adaptations, ultimately resulted in a successful process. This track and trace system provides a clean regulated supply chain, minimizes reimbursement fraud, facilitates fast market recalls, and can flag likely medicine shortages. Staff previously engaged in pharmacy inspections now concentrate on ensuring production quality, which reduces the risk of substandard medicines.

CONCLUSIONS

In Turkey, 4 factors drove the successful implementation of pharmaceutical track and trace: the political determination to eliminate reimbursement fraud, a large pharmaceutical market dominated by a single payer, medicine reimbursement being contingent on verified dispensing and prescription, and flexibility to adapt the system according to the needs of stakeholders during implementation.

The ghost in the data: Evidence gaps and the problem of fake drugs in global health research

For the past several decades, global health research and policy have raised the alarm about the growing threat of counterfeit and low-quality drugs (henceforth 'fakes'). These high-profile and regularly-repeated claims about 'fake drugs' pepper scholarly publications, grey literature, and popular writing. We reviewed much of this work and found that it shares two characteristics that sit awkwardly alongside one another. First, it asserts that fake drugs constitute an urgent threat to lives. Second, it reports trouble with 'gaps' in the evidence on which their claims are based; that data is weaker and less conclusive than anticipated. Given the ubiquity of and urgency with these claims are made, we found this juxtaposition perplexing. To understand this juxtaposition better, we undertook a close reading of the strategies authors employed to negotiate and overcome data and evidence 'gaps' and asked questions about the cultures of scholarly publishing in global health research. We argue that a scholarly commitment to studying fakes despite--rather than because of-the evidence functions to support the continuation of similar research. It also works against asking different questions-for instance regarding the lack of easy access to pharmacological data that might make it possible to know fakes differently.

Importance of medicine quality in achieving universal health coverage

OBJECTIVE

To assess the importance of ensuring medicine quality in order to achieve universal health coverage (UHC).

METHODS

We developed a systems map connecting medicines quality assurance systems with UHC goals to illustrate the ensuing impact of quality-assured medicines in the implementation of UHC. The association between UHC and medicine quality was further examined in the context of essential medicines in low- and middle-income countries (LMICs) by analyzing data on reported prevalence of substandard and falsified essential medicines and established indicators for UHC. Finally, we examined the health and economic savings of improving antimalarial quality in four countries in sub-Saharan Africa: the Democratic Republic of the Congo (DRC), Nigeria, Uganda, and Zambia.

FINDINGS

A systems perspective demonstrates how quality assurance of medicines supports dimensions of UHC. Across 63 LMICs, the reported prevalence of substandard and falsified essential medicines was found to be negatively associated with both an indicator for coverage of essential services (p = 0.05) and with an indicator for government effectiveness (p = 0.04). We estimated that investing in improving the quality of antimalarials by 10% would result in annual savings of $8.3 million in Zambia, $14 million in Uganda, $79 million in two DRC regions, and $598 million in Nigeria, and was more impactful compared to other potential investments we examined. Costs of substandard and falsified antimalarials per malaria case ranged from $7 to $86, while costs per death due to poor-quality antimalarials ranged from $14,000 to $72,000.

CONCLUSION

Medicines quality assurance systems play a critical role in reaching UHC goals. By ensuring the quality of essential medicines, they help deliver effective treatments that lead to less illness and result in health care savings that can be reinvested towards UHC.

Tackling the blind spot of poor-quality medicines in Universal Health Coverage

BACKGROUND

Universal Health Coverage (UHC) is challenged by the prevalence of poor-quality medicines, those that either do not meet required specifications (substandard) or are outrightly fraudulent (falsified), especially in Low- and Middle-Income Countries, LMICs. Whereas poor-quality medicines are a significant burden in these countries, medicine quality still remains a neglected component of UHC programs. This article describes key barriers to quality medicines and presents five select approaches leveraging the scale-up of UHC for medicine quality assurance.

MAIN BODY

Barriers to medicine quality assurance, while numerous, are described in five key inter-related domains as: low political priority, weak regulatory systems capacity, poor access to accredited facilities and licensed outlets, medicine manufacturing and other supply-chain challenges, and lack of public awareness. Five select approaches for leveraging the scale-up of UHC for medicine quality assurance in LMICs are (1): political commitment (2) strengthening the capacity of regulatory authorities and investment in detection technologies as part of national security (3); licensing of medicines outlets and expanding pharmacovigilance (4); strengthening the supply-chain; and (5) public awareness and participation.

CONCLUSIONS

Unchecked, poor-quality medicines can jeopardize UHC. National governments in LMICs need to prioritize medicine quality assurance through enforcing policies, regulatory strengthening and investments in technologies. Healthcare facilities and insurance schemes under UHC also play critical roles through incorporating medicine quality assurance into procurement practices and by promoting awareness among beneficiaries. Tackling medicine quality with a committed systems approach will enhance progress towards UHC implementation.

How moves towards universal health coverage could encourage poor quality drugs: an essay by Elizabeth Pisani

Universal health coverage depends on affordable medicines. But pushing down prices without also investing in quality assurance will increase the sale of substandard and falsified drugs, warns Elizabeth Pisani

Identifying market risk for substandard and falsified medicines: an analytic framework based on qualitative research in China, Indonesia, Turkey and Romania

Introduction: Substandard and falsified medicines undermine health systems. We sought to unravel the political and economic factors which drive the production of these products, and to explain how they reach patients. Methods: We conducted in-depth case studies in China, Indonesia, Turkey and Romania. We reviewed academic papers and press reports (n = 840), developing semi-structured questionnaires. We interviewed regulators, policy-makers, pharmaceutical manufacturers, physicians, pharmacists, patients and academics (n=88). We coded data using NVivo software, and developed an analytic framework to assess national risks for substandard and falsified medicines. We tested the framework against cases reported to the World Health Organization, from countries at all income levels. Results: We found that increasing political commitment to provision of universal health coverage has led to public procurement policies aimed at lowering prices of medical products. In response, legitimate, profit-driven pharmaceutical companies protect their margins by cutting costs, or withdrawing from less profitable markets, while distributors engage in arbitrage. Meanwhile, health providers sometimes protect profits by 'upselling' patients to medicines not covered by insurers. Cost-cutting can undermine quality assurance, leading to substandard or degraded medicines. Other responses contribute to shortages, irrational demand and high prices. All of these provide market opportunities for producers of falsified products; they also push consumers outside of the regular supply chain, providing falsifiers with easy access to customers. The analytic framework capturing these interactions explained cases in most high and middle-income settings; additional factors operate in the poorest countries. Conclusions: Most efforts to secure medicine quality currently focus on product regulation. However, our research suggests market mechanisms are key drivers for poor quality medicines, including where political commitments to universal health coverage are under-resourced. We have developed a framework to guide country-specific, system-wide analysis. This can flag risks and pinpoint specific actions to protect medicine quality, and thus health.
