Impact of QR-Code Medicine Verification Education on Counterfeit Medicine Detection Practices among Adults in Nigeria

Abstract

Counterfeit and substandard medicines remain an important public health concern because the use of falsified or poor-quality medicines may result in treatment failure, adverse health outcomes, antimicrobial resistance, prolonged illness, and preventable death. Adults purchasing medicines in Nigeria may encounter products of uncertain authenticity, particularly when medicines are obtained from informal or poorly regulated sources. Digital medicine-verification technologies, including QR-code verification systems where available, provide an opportunity for consumers to check product information and identify potentially suspicious medicines before use. However, limited awareness of QR-code medicine verification, inadequate digital literacy, uncertainty about verification procedures, and lack of confidence in interpreting verification results may limit its effective use. QR-code medicine verification education provides an opportunity to improve adults' knowledge and practical ability to verify medicines and recognize potentially counterfeit products. Against this background, this study investigates the impact of QR-code medicine verification education on counterfeit medicine detection practices among adults in Nigeria. The study will be anchored on the Technology Acceptance Model, Protection Motivation Theory, and Health Belief Model. The Technology Acceptance Model explains how perceived usefulness and perceived ease of use of QR-code medicine verification systems may influence adults' willingness to adopt and use the technology. Protection Motivation Theory explains how perceived risks associated with counterfeit medicines, perceived severity of harm, response efficacy, response costs, and self-efficacy may influence individuals' motivation to verify medicines before use. The Health Belief Model explains how adults' perceptions of susceptibility to counterfeit-medicine risks, perceived severity, perceived benefits of medicine verification, perceived barriers, and cues to action may influence verification practices. Collectively, these theoretical perspectives provide a suitable framework for explaining how QR-code medicine verification education may influence counterfeit medicine detection practices among adults in Nigeria. The study will adopt a quantitative quasi-experimental or analytical cross-sectional research design. The study population will comprise adults aged 18 years and above who purchase or use medicines in selected urban, semi-urban, and rural communities across Nigeria. A multistage sampling technique will be used to select geopolitical zones, states, local government areas, communities, households, pharmacies, patent and proprietary medicine vendors, and eligible adult medicine consumers. QR-code medicine verification education will be assessed using indicators such as exposure to verification education sessions, frequency and duration of education, knowledge of QR-code verification, awareness of medicine authentication technologies, ability to locate verification codes on medicine packages, knowledge of scanning procedures, understanding of verification results, awareness of warning signs of potentially counterfeit medicines, knowledge of appropriate sources for purchasing medicines, and understanding of appropriate actions when verification results are suspicious or unsuccessful. Counterfeit medicine detection practices will be assessed using indicators such as checking medicine packaging, scanning available QR codes, verifying product information before use, checking batch and expiry information, examining manufacturer details, purchasing medicines from authorized sources, checking for suspicious packaging or labelling, seeking professional assistance when authenticity is uncertain, reporting suspected counterfeit medicines to appropriate authorities, and avoiding the use of medicines that cannot be adequately verified. Data will be collected using structured questionnaires, medicine-verification knowledge assessment tools, practical QR-code scanning tasks, counterfeit medicine detection practice instruments, medicine-package observation checklists, and pre-test and post-test assessments where a quasi-experimental intervention is adopted. Descriptive statistics will be used to summarize participants' demographic and socioeconomic characteristics, medicine-purchasing patterns, digital literacy, previous exposure to medicine-verification education, and counterfeit medicine detection practices. Inferential statistical techniques, including chi-square tests, t-tests, correlation analysis, and logistic or multiple regression analysis where appropriate, will be used to determine the impact of QR-code medicine verification education on counterfeit medicine detection practices. Where a quasi-experimental design is adopted, detection-practice scores before and after the educational intervention may be compared with those of a comparison group to determine changes associated with the intervention. Diagnostic tests will also be conducted to assess the reliability, validity, and robustness of the findings. The study is expected to find that QR-code medicine verification education has a significant positive impact on counterfeit medicine detection practices among adults in Nigeria. Adults exposed to structured and practical verification education are expected to demonstrate improved knowledge and greater use of appropriate medicine-authentication practices than adults without comparable exposure. Education may improve participants' ability to identify verification codes, scan medicine packages, interpret verification results, recognize suspicious product characteristics, purchase medicines from reliable sources, and seek appropriate assistance when medicine authenticity is uncertain. Practical demonstrations using medicine packages and simulated verification scenarios may further improve users' confidence and ability to apply verification procedures correctly. However, limited availability of QR-code verification systems, poor internet connectivity, inadequate smartphone access, low digital literacy, uncertainty about verification results, affordability concerns, and continued access to medicines through informal channels may reduce the effectiveness of education alone. The study therefore expects accessible, practical, consumer-friendly, and culturally appropriate QR-code medicine verification education, supported by reliable authentication technologies and effective medicine regulation, to contribute significantly to improved counterfeit medicine detection practices among adults in Nigeria. The study is expected to contribute to the literature on counterfeit medicine prevention, medicine authentication, digital health, pharmaceutical safety, consumer health education, health literacy, medication safety, public health, and digital technology in healthcare in Nigeria. The findings will provide useful information to the Federal Ministry of Health and Social Welfare, National Agency for Food and Drug Administration and Control, Pharmacists Council of Nigeria, healthcare professionals, pharmacies, patent and proprietary medicine vendors, pharmaceutical manufacturers, digital health technology providers, consumer protection organizations, public health practitioners, development partners, and policymakers regarding strategies for strengthening medicine authentication and consumer protection. The study will also provide evidence-based recommendations for expanding consumer education on digital medicine verification, improving access to medicine-authentication technologies, strengthening public awareness of counterfeit medicine risks, promoting purchases from authorized medicine outlets, improving reporting mechanisms for suspected counterfeit products, and developing sustainable digital medicine-verification programmes across Nigeria.
