Effect of Healthcare Worker Orientation Programmes on Infection Prevention Knowledge among Newly Employed Healthcare Workers in Nigeria

Abstract

Infection prevention and control is essential for protecting patients, healthcare workers, and visitors from healthcare-associated infections and other preventable infectious risks within healthcare facilities. Newly employed healthcare workers may be particularly vulnerable to gaps in infection prevention knowledge because they may be unfamiliar with facility-specific infection prevention policies, standard precautions, hand hygiene procedures, personal protective equipment, waste management practices, environmental cleaning, injection safety, and procedures for managing infectious patients. In Nigeria, inadequate orientation, limited infection prevention training, inconsistent availability of protective equipment, and weak institutional infection prevention systems may affect healthcare workers' preparedness to implement appropriate infection prevention practices. Healthcare worker orientation programmes provide newly employed staff with structured information and practical training on organizational policies, clinical procedures, workplace safety, and infection prevention requirements. Effective orientation may therefore improve healthcare workers' understanding of infection prevention principles and strengthen preparedness for safe clinical practice. Against this background, this study investigates the effect of healthcare worker orientation programmes on infection prevention knowledge among newly employed healthcare workers in Nigeria. The study will be anchored on the Health Belief Model, Social Cognitive Theory, and the Donabedian Model of Healthcare Quality. The Health Belief Model explains how healthcare workers' perceptions of infection risks, severity of healthcare-associated infections, benefits of infection prevention, perceived barriers, and cues to action may influence their knowledge and adoption of preventive practices. Social Cognitive Theory emphasizes learning through observation, practical demonstration, reinforcement, self-efficacy, and interaction with the work environment. The Donabedian Model explains healthcare quality through structure, process, and outcome, with staff orientation representing an important organizational process and infection prevention knowledge serving as a measurable outcome. Collectively, these theoretical perspectives provide a suitable framework for explaining how healthcare worker orientation programmes may influence infection prevention knowledge among newly employed healthcare workers in Nigeria. The study will adopt a quantitative quasi-experimental research design. The study population will comprise newly employed healthcare workers in selected public and private hospitals and primary healthcare facilities across Nigeria. Participants may include doctors, nurses, pharmacists, laboratory professionals, community health workers, healthcare assistants, and other clinical personnel who have recently commenced employment. A multistage sampling technique will be used to select states, local government areas, healthcare facilities, departments, and eligible newly employed healthcare workers. Healthcare worker orientation programmes will be assessed using indicators such as availability of formal orientation programmes, timing of orientation after employment, duration of orientation, coverage of infection prevention and control topics, hand hygiene training, use of personal protective equipment, standard precautions, transmission-based precautions, sharps safety, injection safety, healthcare waste management, environmental cleaning, sterilization and disinfection, occupational exposure management, infection prevention documentation, practical demonstrations, simulation activities, refresher sessions, and availability of trained facilitators. Infection prevention knowledge will be assessed using indicators such as knowledge of standard precautions, appropriate hand hygiene procedures, personal protective equipment selection and use, infection transmission routes, respiratory hygiene, sharps injury prevention, safe injection practices, healthcare waste segregation, environmental cleaning, sterilization and disinfection, exposure management, and infection prevention responsibilities. Data will be collected using structured questionnaires, standardized knowledge-assessment instruments, orientation attendance records, training materials, facility infection prevention documents, and observation checklists where appropriate. Infection prevention knowledge will be assessed before and after participation in the orientation programme. Descriptive statistics will be used to summarize participants' demographic and professional characteristics, orientation exposure, and infection prevention knowledge levels. Inferential statistical techniques, including paired sample tests, chi-square tests, correlation analysis, and logistic or multiple regression analysis where appropriate, will be used to determine the effect of orientation programmes on infection prevention knowledge. Diagnostic tests will also be conducted to assess the reliability, validity, and robustness of the findings. The study is expected to find that healthcare worker orientation programmes have a significant positive effect on infection prevention knowledge among newly employed healthcare workers in Nigeria. Newly employed healthcare workers who participate in comprehensive orientation programmes are expected to demonstrate improved knowledge of hand hygiene, standard precautions, personal protective equipment, sharps safety, injection safety, healthcare waste management, environmental cleaning, sterilization, disinfection, and occupational exposure management compared with their pre-orientation knowledge levels. Practical demonstrations and interactive training are expected to strengthen knowledge retention and improve healthcare workers' understanding of infection prevention responsibilities. Early orientation may also help newly employed workers adapt to facility-specific infection prevention policies and procedures. However, inadequate orientation duration, limited training resources, shortages of trained infection prevention personnel, high staff turnover, insufficient protective equipment, and inconsistent follow-up training may reduce the effectiveness of orientation programmes. The study therefore expects structured, timely, comprehensive, and adequately supported healthcare worker orientation programmes to contribute significantly to improved infection prevention knowledge among newly employed healthcare workers in Nigeria. The study is expected to contribute to the literature on healthcare worker orientation, infection prevention and control, infection prevention knowledge, healthcare-associated infection prevention, occupational safety, patient safety, healthcare quality, and public health in Nigeria. The findings will provide useful information to the Federal Ministry of Health and Social Welfare, National Primary Health Care Development Agency, state ministries of health, hospital management boards, healthcare facilities, infection prevention and control committees, healthcare training institutions, professional regulatory bodies, healthcare administrators, and policymakers regarding strategies for improving infection prevention preparedness among newly employed staff. The study will also provide evidence-based recommendations for institutionalizing comprehensive orientation programmes, ensuring early infection prevention training after employment, strengthening practical and simulation-based learning, providing refresher training, improving access to infection prevention resources, monitoring knowledge retention, and integrating infection prevention orientation into staff onboarding policies across Nigerian healthcare facilities.
