1.1 Introduction
Medication administration error is commonly defined as any preventable event that leads to inappropriate medication use or patient harm while the medication is under the control of a healthcare professional, patient, or consumer (National Coordinating Council for Medication Error Reporting and Prevention, 2020). Medication administration errors have become a major global concern in healthcare systems because they significantly affect the quality and safety of patient care. According to the World Health Organization, medication errors contribute to considerable patient harm worldwide and are estimated to cost billions of dollars annually in additional healthcare expenses and prolonged hospital stays. However, the administration stage remains particularly critical because it is the last point at which an error may be detected before the medication reaches the patient (World Health Organization, 2017).
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are significance of the study, scope of work, research hypothesis and questions, limitation of the study and definition of terms.
1.2 Background of Study
The administration of medication is one of the most essential responsibilities of nurses in healthcare institutions. Safe medication administration ensures that patients receive the correct treatment and achieve the desired therapeutic outcomes. However, medication administration errors remain a persistent challenge in healthcare systems across the world. Medication administration error refers to any deviation from a physician's prescription, medication order, or established medication administration standards that may lead to inappropriate medication use or potential harm to patients. These errors may occur during the preparation, dosage calculation, timing, or route of drug administration, and they often involve nurses who are responsible for the final stage of medication delivery to patients.
Globally, patient safety has become a major concern in modern healthcare practice due to the high prevalence of medical errors, particularly those related to medication. The World Health Organization (2017) stated that medication errors are among the leading causes of avoidable harm in healthcare systems and contribute significantly to patient morbidity and mortality. The organization further reported that millions of patients around the world experience preventable medication-related injuries every year, which places an additional burden on healthcare institutions and professionals. Medication safety therefore remains a critical aspect of quality healthcare delivery, and healthcare organizations continue to emphasize strategies aimed at reducing medication administration errors (World Health Organization, 2017).
Scholars and healthcare researchers have extensively examined the factors responsible for medication administration errors among nurses. Keers, Williams, Cooke, and Ashcroft (2013) asserted that medication administration errors frequently occur due to human, environmental, and organizational factors within healthcare institutions. Their study revealed that issues such as interruptions during medication rounds, heavy workloads, time pressure, and lack of adequate staffing significantly increase the likelihood of medication errors among nurses. These factors often interfere with nurses' concentration and decision-making ability during medication preparation and administration.
Similarly, Reason (2000) contended that errors in healthcare systems are rarely the result of individual negligence alone but are often linked to systemic failures within the work environment. According to this perspective, factors such as poor communication among healthcare professionals, unclear drug prescriptions, inadequate supervision, and ineffective hospital policies may contribute to medication administration errors.
In many developing countries, including Nigeria, the occurrence of medication administration errors is often influenced by structural challenges within the healthcare system. Oshikoya and Oreagba (2011) reported that medication errors are relatively common in Nigerian healthcare facilities due to factors such as inadequate staffing, limited resources, and insufficient training opportunities for healthcare professionals. These conditions often place considerable pressure on nurses who are responsible for administering medications to a large number of patients within a limited period of time. As a result, the risk of medication errors increases when nurses are required to perform complex tasks under stressful conditions.
Ayorinde and Alabi (2019) stated that nursing workload and staff shortages in many Nigerian hospitals contribute significantly to medication administration errors. When nurses are responsible for a high number of patients during their shifts, the chances of fatigue, stress, and reduced attention to detail increase. These conditions may lead to incorrect dosage calculations, omission of medications, or administration of drugs at the wrong time. Such errors may compromise patient safety and reduce the overall quality of healthcare services provided in hospitals. This study is set against the backdrop of the growing concern about medication administration errors and the need to identify the factors contributing to such errors among nurses in Warri Central Hospital.
1.3 Statement of Problems
Investigation revealed that medication administration is a fundamental responsibility of nurses and is widely recognized as a critical component of patient care and safety. The process of administering medication involves several stages, including prescription interpretation, preparation, dosage calculation, timing, and monitoring of patient responses. Globally, medication errors remain a persistent challenge within healthcare systems, and nurses are often at the center of this issue because they are directly responsible for administering medications to patients (WHO, 2017).
In many healthcare institutions, particularly in developing countries, the complexity of the healthcare environment, combined with limited resources and heavy workloads, is associated with a higher likelihood of medication administration errors. Nurses frequently work under conditions characterized by staff shortages, high patient–nurse ratios, fatigue, and time pressure. Research indicates that factors such as inadequate training, poor communication among healthcare professionals, lack of standardized procedures, and interruptions during medication rounds contribute significantly to medication errors in hospitals (Keers, Williams, Cooke, & Ashcroft, 2013).
Furthermore, issues such as illegible prescriptions, inadequate supervision, and the absence of modern technological support systems for medication management may contribute to medication administration errors within healthcare facilities (Oshikoya & Oreagba, 2011). It is against this backdrop that this study seeks to investigate the factors contributing to medication administration errors among nurses.
1.4 Aim and Objectives of Study
The aim of this study is to identify and analyze the factors contributing to medication administration errors among nurses in Warri Central Hospital. In achieving this aim, the following specific objectives were laid out as follows:
- To determine the frequency and types of medication administration errors among nurses at Warri Central Hospital.
- To examine the impact of nurse workload, staff shortages, and interruptions on medication administration errors.
- To assess the role of communication, supervision, and training in preventing medication administration errors.
- To identify organizational and systemic factors within the hospital that contribute to medication errors.
- To provide recommendations for improving medication safety and nursing practice at Warri Central Hospital.
