Effect of Personal Protective Equipment Availability on Infection Prevention Practices among Healthcare Workers in Nigeria

Abstract

Personal protective equipment (PPE) is an important component of infection prevention and occupational safety in healthcare settings because it provides a physical barrier between healthcare workers and potentially infectious materials. Personal protective equipment availability refers to the presence, adequacy, accessibility, quality, and consistent supply of appropriate protective equipment required for healthcare activities. Such equipment may include gloves, medical masks, respirators, protective gowns or aprons, eye protection, face shields, and other protective items appropriate to specific clinical risks. Infection prevention practices refer to the procedures and behaviours implemented by healthcare workers to prevent and control the transmission of infectious agents within healthcare facilities. These practices include standard precautions, appropriate use of PPE, hand hygiene, safe injection practices, respiratory hygiene, appropriate waste management, sterilization and disinfection, and safe handling of blood and body fluids. In Nigeria, shortages, stock-outs, inappropriate sizing, poor-quality PPE, inadequate procurement systems, and inconsistent distribution may limit healthcare workers' ability to follow recommended infection prevention procedures. Adequate and consistently available PPE may improve healthcare workers' capacity to comply with infection prevention standards and reduce occupational exposure to infectious hazards. Against this background, this study investigates the effect of personal protective equipment availability on infection prevention practices among healthcare workers in Nigeria. The study is anchored on Donabedian's Structure-Process-Outcome Model, the Theory of Planned Behavior, and the Hierarchy of Controls. Donabedian's Model identifies PPE and other infection-control resources as important structural components that influence healthcare processes and outcomes. The Theory of Planned Behavior explains how healthcare workers' attitudes, perceived expectations, and perceived behavioural control may influence their adoption of recommended infection prevention practices, while PPE availability contributes to the environmental conditions necessary for such practices. The Hierarchy of Controls recognizes PPE as an important protective measure for reducing exposure to occupational hazards when elimination, substitution, engineering controls, and administrative controls cannot fully remove the risk. Collectively, these theoretical perspectives provide a suitable framework for explaining how PPE availability may influence infection prevention practices among healthcare workers. The study will adopt a quantitative cross-sectional research design. Primary data will be collected from selected healthcare facilities in Nigeria using structured PPE availability assessment checklists, healthcare worker questionnaires, direct observation tools, stock records, procurement records, and infection prevention and control reports. A multistage sampling technique will be employed to select states, healthcare facilities, departments, healthcare workers, and relevant patient-care areas. PPE availability will be assessed using indicators such as availability of gloves, medical masks, respirators, protective gowns or aprons, eye protection, face shields, appropriate PPE sizes, adequacy of stock, frequency of stock-outs, accessibility at points of care, quality and condition of PPE, procurement reliability, storage arrangements, and availability during high-risk procedures. Infection prevention practices will be assessed using indicators such as adherence to standard precautions, appropriate PPE use, hand hygiene, safe injection practices, respiratory hygiene, safe handling of blood and body fluids, healthcare waste management, environmental cleaning, sterilization and disinfection, and occupational exposure prevention. Direct observation will be used where feasible to complement self-reported information and provide more objective measures of actual infection prevention practices. Descriptive statistics will be used to summarize PPE availability, stock conditions, healthcare worker characteristics, and infection prevention practices. Inferential statistical techniques, including chi-square tests, correlation analysis, and multiple regression analysis, will be used to determine the effect of PPE availability on infection prevention practices. Diagnostic tests will also be conducted to assess the reliability of research instruments, model assumptions, goodness of fit, multicollinearity, and robustness of the findings. The study is expected to find that adequate and consistent availability of personal protective equipment has a significant positive effect on infection prevention practices among healthcare workers in Nigeria. Healthcare workers operating in facilities with sufficient supplies of appropriate, accessible, and good-quality PPE are expected to demonstrate higher compliance with recommended infection prevention procedures. Reliable availability of PPE is expected to reduce practical barriers to the appropriate use of protective equipment during patient care and other high-risk procedures. Consistent supplies may also improve healthcare workers' confidence in performing infection-prone procedures and reduce the likelihood of reusing inappropriate protective items because of shortages. Conversely, frequent PPE stock-outs, inadequate quantities, poor quality, inappropriate sizes, and limited access at points of care are expected to reduce compliance and increase the risk of occupational exposure and infection transmission. However, PPE availability alone may not guarantee effective infection prevention because healthcare worker knowledge, training, attitudes, workload, institutional supervision, availability of other infection-control resources, and organizational safety culture may also influence practices. Therefore, PPE availability should be supported by continuous training, monitoring, adequate infection-control infrastructure, and effective institutional policies. The study is expected to contribute to the literature on personal protective equipment availability, infection prevention practices, occupational health, healthcare worker safety, infection prevention and control, patient safety, healthcare quality, and public health in Nigeria by providing empirical evidence on the role of PPE availability in supporting safe healthcare practices. The findings will provide useful information to the Federal Ministry of Health and Social Welfare, Nigeria Centre for Disease Control and Prevention, state ministries of health, hospital management boards, primary healthcare authorities, infection prevention and control committees, occupational health units, healthcare facility administrators, healthcare workers, development partners, and policymakers regarding strategies for improving PPE availability and infection prevention. The study will also provide evidence-based recommendations for strengthening PPE procurement and supply systems, maintaining adequate emergency stock levels, improving distribution to points of care, ensuring appropriate PPE quality and sizing, reducing stock-outs, strengthening inventory monitoring, providing PPE-use training, and establishing regular monitoring of PPE availability and infection prevention compliance across Nigerian healthcare facilities.
