Root Cause Analysis for Medication Errors in Healthcare
This paper examines Root Cause Analysis (RCA) as a structured quality improvement methodology for identifying and permanently eliminating adverse events in healthcare settings. Using a medication administration error as a case study, the paper traces how active and latent errors — including nurse overwork, look-alike drug vials, and reliance on portable medication carts instead of Automated Dispensing Machines (ADMs) — combine to produce patient safety failures. The paper argues that a systems approach, rather than individual blame, is essential for uncovering root causes and designing durable solutions such as portable ADMs, revised staffing ratios, and manufacturer-level packaging reforms.

What makes this paper effective
- Grounds every analytical claim in cited sources, maintaining academic credibility throughout a relatively short paper.
- Uses a concrete, specific case scenario — an overworked nurse, look-alike vials, and a single ADM — to make abstract RCA concepts tangible.
- Moves logically from definition to problem identification to solution, giving the paper a clear and persuasive arc.
Key academic technique demonstrated
The paper demonstrates applied theoretical framing: it introduces RCA as a formal methodology, then immediately tests that framework against a real-world healthcare scenario. This technique — define, apply, analyze, recommend — is characteristic of quality-improvement and health-administration writing and shows how theory guides practical decision-making.
Structure breakdown
The paper opens with a definitional section establishing what RCA is and why it avoids individual blame in favor of systems thinking. It then contextualizes RCA within patient safety, narrates the specific medication error event, implicitly separates active errors (wrong medication administered) from latent errors (staffing levels, equipment design, packaging), and closes with a recommendations paragraph proposing portable ADMs, staffing reviews, and manufacturer policy changes. References follow APA 7 format.
Introduction to Root Cause Analysis
Root Cause Analysis (RCA) is a structured methodology for analyzing serious adverse events. According to Wachman et al. (2018), RCA is a quality improvement tool that defines the main problem and identifies the actions necessary to eliminate that problem permanently. The objective is to ensure that an organization does not continue addressing only minor symptoms of a deeper problem (Leveson et al., 2020). To avoid repeatedly fixing surface-level issues, the focus should be on identifying the true root cause and implementing a permanent solution.
Determining the true root cause of a problem is difficult. Therefore, an analysis is conducted using one or more tools to separate the actual problem from its symptoms. RCA allows an organization to determine what happened, why it happened, and how the problem can be eliminated so it does not recur (Wachman et al., 2018). RCA focuses on identifying the underlying conditions that increase the likelihood of errors, rather than falling into the common trap of blaming individual workers. A systems approach is used to identify both active and latent errors (Leveson et al., 2020). RCA is widely used for detecting safety hazards across many industries, including healthcare.
RCA and Patient Safety in Healthcare Organizations
A healthcare organization that wants to improve patient care and outcomes should strive to implement RCA. This quality improvement model allows the organization to identify areas where failures are occurring — failures that could lead to adverse events — and to determine how those errors can be eliminated (Billstein-Leber et al., 2018). The adverse event addressed in this analysis is patient safety. Many errors can occur in a healthcare facility related to patient care, and each error should be analyzed using a multidisciplinary team.
The team analyzes the sequence of events that led to an error in order to identify how the error occurred by examining active errors, and why it occurred by identifying latent errors. The team's ultimate goal is to prevent the error from recurring.
The Medication Error: Case Description
The healthcare organization in this case has an Automated Dispensing Machine (ADM) designed to ensure that nurses retrieve only the correct medication for each patient. However, to save time, most nurses prefer to use portable medication carts that allow them to carry all patient medications at once, rather than making repeated trips between the ADM and the patient's bedside (Billstein-Leber et al., 2018). The use of portable medication carts is also driven by the fact that the nursing unit has only one ADM. As a result, the medication error the organization sought to eliminate persists, because the risk of administering the wrong medication increases — particularly when medications are stored in look-alike vials.
