Impact of Roadside Emergency Medical Services on Survival among Road Traffic Accident Victims in Nigeria

Abstract

Road traffic accidents remain a major public health and injury-related challenge in Nigeria, contributing substantially to preventable deaths, disabilities, and long-term health consequences. Victims of road traffic accidents may experience life-threatening conditions such as severe bleeding, head injuries, fractures, spinal injuries, respiratory compromise, and shock that require immediate medical attention. The period between the occurrence of an accident and arrival at a healthcare facility is therefore critical for preventing avoidable deaths. Roadside emergency medical services provide immediate medical assistance at or near the scene of a road traffic accident and may include rapid emergency response, first aid, bleeding control, airway management, cardiopulmonary resuscitation, immobilization, stabilization, and safe transportation to an appropriate healthcare facility. However, access to effective roadside emergency medical services in Nigeria may be limited by inadequate emergency response infrastructure, insufficient ambulances, shortages of trained emergency personnel, poor road networks, traffic congestion, communication challenges, and delays in reaching accident scenes. Survival among road traffic accident victims refers to the proportion of accident victims who remain alive following the injury event and emergency care over a specified period, particularly until arrival at or discharge from a healthcare facility. Against this background, this study investigates the impact of roadside emergency medical services on survival among road traffic accident victims in Nigeria. The study will be anchored on the Chain of Survival Model, the Three Delays Model, and the Health Systems Framework. The Chain of Survival Model emphasizes early recognition, rapid emergency response, immediate life-saving interventions, timely transportation, and definitive medical care as essential components of improving survival following life-threatening injuries. The Three Delays Model provides a framework for understanding delays in initiating emergency assistance, reaching appropriate healthcare facilities, and receiving adequate treatment after arrival. The Health Systems Framework emphasizes service delivery, health workforce, medical technologies, communication systems, transportation, financing, and accessibility as important components of an effective emergency healthcare system. Collectively, these theoretical perspectives provide a suitable framework for explaining how roadside emergency medical services may influence survival among road traffic accident victims in Nigeria. The study will adopt a quantitative retrospective cohort or cross-sectional research design, depending on the availability of emergency medical and hospital records. The study population will comprise road traffic accident victims who receive roadside emergency assistance and subsequent care in selected locations and healthcare facilities in Nigeria. A multistage sampling technique will be used to select states, emergency response stations, road corridors, hospitals, and eligible accident victims or medical records. Roadside emergency medical services will be assessed using indicators such as emergency response availability, response time, presence of trained emergency personnel, availability of ambulances, first-aid provision, bleeding control, airway management, immobilization, emergency communication, pre-hospital stabilization, transportation time, and coordination between emergency responders and receiving healthcare facilities. Survival will be assessed using indicators such as survival to hospital arrival, survival to hospital discharge, mortality following the accident, and survival within specified periods after the injury where follow-up data are available. Data will be collected from emergency medical service records, ambulance records, accident registers, hospital records, emergency department records, trauma registers, and structured questionnaires where appropriate. Descriptive statistics will be used to summarize accident characteristics, emergency service utilization, response patterns, and survival outcomes. Inferential statistical techniques, including chi-square tests, correlation analysis, logistic regression, and survival analysis where appropriate, will be used to determine the impact of roadside emergency medical services on survival. Diagnostic tests will also be conducted to assess the reliability, validity, and robustness of the findings. The study is expected to find that timely and effective roadside emergency medical services have a significant positive impact on survival among road traffic accident victims in Nigeria. Victims who receive prompt emergency assistance at the accident scene are expected to have a greater likelihood of surviving than victims who experience substantial delays before receiving emergency care. Early control of severe bleeding, airway management, cardiopulmonary resuscitation where required, immobilization, stabilization, and rapid transportation to appropriate healthcare facilities may prevent deterioration and reduce avoidable deaths. The availability of trained emergency personnel and functional ambulances may further improve the quality and timeliness of pre-hospital care. Conversely, inadequate emergency response coverage, long response times, limited ambulance availability, poor communication systems, traffic congestion, inadequate equipment, shortages of trained personnel, and delays in transportation may negatively affect survival outcomes. The effectiveness of roadside emergency medical services may also depend on the capacity of receiving hospitals to provide timely definitive trauma care. The study is expected to contribute to the literature on roadside emergency medical services, road traffic injuries, trauma care, emergency medical response, pre-hospital care, injury prevention, survival outcomes, epidemiology, and public health in Nigeria. The findings will provide useful information to the Federal Ministry of Health and Social Welfare, National Emergency Medical Treatment Committee, state ministries of health, emergency medical service agencies, Federal Road Safety Corps, hospitals, emergency physicians, paramedics, trauma-care providers, development partners, and policymakers regarding strategies for improving emergency response to road traffic injuries. The study will also provide evidence-based recommendations for expanding emergency medical service coverage, reducing emergency response times, increasing the availability of functional ambulances and emergency equipment, strengthening training of emergency medical personnel, improving emergency communication systems, establishing coordinated referral networks, improving roadside first-aid capacity, and strengthening trauma-care systems to reduce preventable deaths from road traffic accidents across Nigeria.
