Medication Errors: Causes, Costs, and Prevention Strategies
This paper examines medication errors — defined as any preventable incident that may lead to inappropriate medication use or patient harm — through a review of key literature. Drawing on findings from Cloete (2015), Athanasakis (2012), Choi et al. (2016), and Chen et al. (2017), the paper explores the systemic and individual factors that contribute to medication errors, including nursing workload, safety culture, and distractions during medication administration. It also considers the significant economic costs associated with these errors and discusses evidence-based prevention strategies, with particular emphasis on nurse education, clinical pharmacist oversight, and organizational safety protocols.

What makes this paper effective
- Systematically synthesizes multiple peer-reviewed sources to build a cumulative picture of medication error causes and prevention strategies.
- Clearly ties each source's findings to a broader argument, showing how individual studies reinforce one another (e.g., Athanasakis confirming Cloete's findings on nursing workload and education).
- Grounds abstract policy concerns in concrete data, such as the cost figures from Choi et al.'s decomposition models, which strengthen the case for error reduction.
Key academic technique demonstrated
The paper demonstrates annotated literature synthesis — each source is summarized, evaluated for relevance, and connected to the paper's central argument. Rather than treating each study in isolation, the author explicitly notes where sources corroborate one another, modeling how to build an evidence-based argument from multiple references.
Structure breakdown
The paper opens with a definition of medication errors and their consequences, then states the research objective and methodology. The body reviews three primary studies (Cloete, Athanasakis, Choi et al.) in sequence, with commentary on each. A brief summary section integrates the findings and introduces Chen et al.'s recommendations as a practical conclusion. The structure mirrors a standard literature review format appropriate for an introductory healthcare informatics course.
Introduction: Defining Medication Errors
A medication error is any preventable incident that could result in — or contribute to — inappropriate medication use or patient harm. Such incidents may be associated with the professional activities of healthcare personnel across a wide range of functions, including prescribing, order communication, product labeling, packaging, nomenclature, compounding, dispensing, distribution, administration, monitoring, education, and the use of healthcare solutions and systems.
While medication errors may arise from systemic problems or individual human mistakes, they can result in serious physical harm and, in some cases, death. These avoidable mistakes may also impose significant economic, psychological, and emotional stress on both healthcare organizations and individual providers (QuckSmart, 2017).
Healthcare Informatics and Research Objectives
The objective of this paper is to gather sufficient information to understand the implications of medication errors and to identify what can be done to reduce or eliminate them. The approach adopted here follows a progression from acquiring and synthesizing information, to attaining knowledge from that synthesized data, and ultimately to developing practical wisdom. Keywords were searched in online academic databases, and relevant sources were examined in detail.
Keywords searched: medication errors, impact of medication errors, prevention of medication errors, avoiding medication errors.
Nursing Practice and Contributing Factors
Cloete (2015) found that medication errors remain the leading cause of unintentional patient harm. These errors create negative outcomes that compromise patient safety and impose a significant financial burden on healthcare systems. Prevention of medication errors — which can occur at any stage from preparing and dispensing medicines to prescribing them — is critical to maintaining a safe and effective healthcare environment (Cloete, 2015).
According to Cloete (2015), approximately 35% of errors that harm patients occur during the nursing administration stage, making the supervision of medicines a particularly high-risk activity. Cloete (2015) identifies a range of contributing factors, the most significant being organizational safety culture. Additional factors specific to nurses include patient acuity, nurse workload, distractions and interruptions during medication administration, the complexity of certain medication calculations and administration methods, and nursing failure to follow established guidelines or policies.
This research is essential for understanding the root causes of medication errors. Cloete (2015) identifies specific problem areas — including safety culture and medication administration practices — and highlights distractions and workload as probable explanations. The information is directly applicable because it outlines likely causes and points toward concrete corrective actions.
Athanasakis (2012) reached similar conclusions, finding that medication supervision of patients is a central component of nursing practice and one that carries a high risk of medication errors. The underlying factors may be systemic or individual. To prevent errors before they occur, establishing robust safety protocols is critical. The aim of Athanasakis (2012) was to explore the safety measures adopted by nursing professionals to prevent medication errors. A literature search covering ScienceDirect, Medline, and the Cochrane Library was conducted, retrieving publications from January 2000 to August 2011. Results indicated that effective safety measures address medications planning and administration, nurses' ability to calculate dosages accurately, nursing education, oral medication prescribing practices, interdisciplinary cooperation, nursing management, and broader changes to health system medication management (Athanasakis, 2012).
Prevention Strategies and Safety Measures
Athanasakis (2012) reviews the preventive actions taken by nurses following medication errors. The evidence makes clear that a wide range of variables must be addressed within healthcare units to achieve consistently low rates of medication mistakes. Athanasakis (2012) also underscores the need for additional research to establish the effectiveness of each specific intervention. By focusing on medication supervision and the educational level of nurses, Athanasakis (2012) corroborates the findings of Cloete (2015). Together, these studies translate data into actionable knowledge about how medication errors can be prevented.
A key implication from this body of research is that nurse education and interdisciplinary cooperation are not peripheral concerns but central pillars of any effective error-reduction strategy. Organizational commitment to a culture of safety — from front-line nursing staff through to management — is consistently identified as essential across the literature reviewed.
