Impact of Blood-Borne Infection Education on Occupational Exposure Prevention Practices among Healthcare Workers in Nigeria

Abstract

Blood-borne infections are an important occupational health and public health concern among healthcare workers because occupational exposure to infected blood and other potentially infectious body fluids can result in the transmission of serious infections. Healthcare workers may be exposed through needle-stick injuries, sharps injuries, splashes to the eyes or mucous membranes, contact with broken skin, unsafe injection practices, blood collection procedures, surgical procedures, and inappropriate handling of contaminated materials. Blood-borne infection education provides healthcare workers with knowledge and practical skills relating to common blood-borne pathogens, routes of transmission, occupational risk factors, standard precautions, hand hygiene, appropriate use of personal protective equipment, safe injection and sharps practices, safe handling of blood and body fluids, post-exposure prophylaxis, exposure reporting, vaccination, and other preventive measures. Occupational exposure prevention practices refer to behaviours and procedures adopted by healthcare workers to reduce the risk of exposure to blood and other potentially infectious materials, including appropriate use of personal protective equipment, safe handling and disposal of sharps, correct injection practices, appropriate management of blood and body fluids, prompt reporting of occupational exposures, and timely access to post-exposure care. In Nigeria, inadequate knowledge of blood-borne infection risks, limited availability of protective equipment and safety devices, heavy workloads, insufficient staffing, inadequate sharps-disposal facilities, weak occupational health systems, and inconsistent implementation of infection prevention and control measures may affect occupational exposure prevention practices among healthcare workers. Effective blood-borne infection education may improve healthcare workers' knowledge, risk perception, practical skills, and adherence to recommended exposure prevention procedures. Against this background, this study investigates the impact of blood-borne infection education on occupational exposure prevention practices among healthcare workers in Nigeria. The study is anchored on Social Cognitive Theory, the Health Belief Model, and the Knowledge-Attitude-Practice framework. Social Cognitive Theory emphasizes the interaction between knowledge, self-efficacy, behavioural capabilities, social influences, and environmental conditions in shaping occupational exposure prevention behaviour. The Health Belief Model explains preventive occupational health behaviour through perceived susceptibility, perceived severity, perceived benefits, perceived barriers, and cues to action, providing a basis for understanding healthcare workers' adoption of blood-borne infection prevention practices. The Knowledge-Attitude-Practice framework provides a basis for examining how improved knowledge and attitudes resulting from blood-borne infection education may influence occupational exposure prevention practices. Collectively, these theoretical perspectives provide a suitable framework for explaining how blood-borne infection education may influence occupational exposure prevention practices among healthcare workers in Nigeria. The study will adopt a quantitative quasi-experimental research design. Primary data will be collected from healthcare workers in selected public and private healthcare facilities in Nigeria using a structured self-administered questionnaire, blood-borne infection knowledge assessment, and an observational occupational exposure prevention checklist. A multistage sampling technique will be employed to select states, local government areas, healthcare facilities, departments, and eligible healthcare workers. Where feasible, selected healthcare facilities or healthcare worker groups will be assigned to intervention and comparison groups. Healthcare workers in the intervention group will receive structured blood-borne infection education covering common blood-borne pathogens, routes of transmission, occupational exposure risks, standard precautions, hand hygiene, personal protective equipment, safe injection practices, sharps safety, safe handling of blood and body fluids, post-exposure procedures, exposure reporting, vaccination, and access to post-exposure prophylaxis. Occupational exposure prevention practices will be assessed using indicators such as appropriate use of personal protective equipment, safe handling and disposal of sharps, avoidance of unsafe needle recapping, appropriate management of blood and body fluids, safe injection practices, prompt reporting of occupational exposures, and knowledge of and compliance with post-exposure procedures. Where feasible, direct observational assessment will complement self-reported information to improve measurement accuracy. Descriptive statistics will be used to summarize healthcare workers' sociodemographic and professional characteristics, blood-borne infection knowledge, exposure to education, and occupational exposure prevention practices. Inferential statistical techniques, including chi-square tests, paired-sample tests, independent-sample tests, and logistic or multiple regression analysis, will be used to determine the impact of blood-borne infection education on occupational exposure prevention practices. Where appropriate, pre-intervention and post-intervention practice scores will be compared. Diagnostic tests will also be conducted to assess the reliability of the research instruments, model assumptions, goodness of fit, and robustness of the findings. The study is expected to find that blood-borne infection education has a significant positive impact on occupational exposure prevention practices among healthcare workers in Nigeria. Healthcare workers exposed to structured blood-borne infection education are expected to demonstrate improved knowledge of occupational exposure risks and greater compliance with recommended preventive practices. Education may improve appropriate use of personal protective equipment, safe injection practices, sharps handling and disposal, management of blood and body fluids, exposure reporting, and awareness of post-exposure procedures. It may also improve workers' understanding of the importance of vaccination and prompt access to appropriate post-exposure care following occupational exposure. However, education alone may not guarantee sustained occupational exposure prevention practices because healthcare workers may continue to face barriers such as inadequate personal protective equipment, shortages of safety devices, insufficient sharps containers, heavy workloads, staff shortages, inadequate occupational health services, and weak institutional supervision. Consequently, blood-borne infection education is expected to be most effective when supported by adequate protective equipment and safety devices, functional occupational health services, accessible post-exposure care, regular supervision, vaccination programmes, and strong infection prevention and control systems. The study is expected to contribute to the literature on blood-borne infection prevention, occupational exposure, healthcare worker safety, infection prevention and control, occupational health, health education, and public health in Nigeria by providing empirical evidence on the impact of blood-borne infection education on occupational exposure prevention practices among healthcare workers. The findings will provide useful information to the Federal Ministry of Health and Social Welfare, Nigeria Centre for Disease Control and Prevention, National Primary Health Care Development Agency, state ministries of health, healthcare facility managers, infection prevention and control committees, occupational health professionals, professional healthcare associations, public health practitioners, development partners, and policymakers regarding strategies for reducing occupational exposure to blood-borne infections. The study will also provide evidence-based recommendations for strengthening blood-borne infection education, improving access to personal protective equipment and safety devices, strengthening occupational health and post-exposure services, promoting vaccination, improving exposure reporting systems, conducting regular compliance monitoring, and protecting healthcare workers from preventable occupational exposure across healthcare facilities in Nigeria.
