## 문제

A nurse manager is conducting a root cause analysis following a medication error that resulted in a patient receiving the wrong medication. Which action should the nurse manager prioritize during the root cause analysis process?

## 보기

1. Identify the individual staff member responsible for the error and document disciplinary actions
2. Focus on identifying system failures and environmental factors that contributed to the error **✔ 정답**
3. Review the patient's medical history to determine if the wrong medication caused harm
4. Implement immediate policy changes to prevent similar errors from occurring

**정답: 2**

## 해설

Root cause analysis prioritizes identifying system failures and environmental factors over individual blame to prevent future errors. Other options focus on blame, harm assessment, or premature policy changes, which are less effective for systemic improvement.

Understanding Root Cause Analysis (RCA) in Nursing Management

When a medication error occurs, the immediate instinct might be to find the person who made the mistake. However, in modern healthcare safety science, the primary goal of a root cause analysis is not to assign individual blame, but to uncover the deeper, systemic weaknesses that allowed the error to happen. This approach is fundamental to building a just culture, where we distinguish between human error, at-risk behavior, and reckless behavior.

The correct priority is to focus on identifying system failures and environmental factors that contributed to the error. This is because most errors are the end result of a chain of latent failures within the system, not isolated acts by a single person. The provided research strongly supports this principle. A study on insulin administration errors utilized RCA to identify "underlying causal factors" and then implemented continuous improvement strategies targeting these system-level issues to mitigate nursing adverse events [1]. The intervention was not about retraining one nurse but about changing the management system.

Similarly, in the high-stakes environment of prehospital pediatric medication administration, where dosing errors persist at a rate of approximately 31%, researchers used simulation-based RCA to look beyond the documented error characteristics. Their explicit purpose was to identify the "underlying latent conditions in the emergency medical services (EMS) system" [2]. This demonstrates that even when errors are frequent and well-characterized, the solution lies in analyzing the system—such as protocols, equipment design, and communication structures—not just the individual paramedic's actions.

The process of RCA involves mapping out a causal chain. For instance, an RCA of a clinical trial randomization error revealed a chain consisting of "physical causes" and "study-level causes," which then informed institutional-level corrective and preventative actions (CAPA) [3]. This illustrates that a single error can have multiple contributing factors at different levels of an organization, from the physical workspace to the study protocol design. The nurse manager's role is to facilitate this deep dive, asking "why" repeatedly until the root system vulnerabilities are exposed.

Let's examine why the other options are not the priority during the RCA process:

- Identifying the individual staff member for disciplinary action prematurely shuts down the investigative process. It creates a culture of fear and prevents the reporting of near misses, which are crucial for proactive safety improvement. While accountability is important, it is addressed separately after the RCA determines if a system failure or a truly reckless individual act was the primary cause.

- Reviewing the patient's medical history to determine harm is a critical clinical task for the patient's immediate care, but it is not the focus of the RCA meeting itself. The RCA is a separate, retrospective, systems-focused analysis. The patient's outcome is a known event that triggers the RCA; the analysis then works backward to find the systemic causes.

- Implementing immediate policy changes before a thorough analysis is completed is a common pitfall. This can lead to changes that address a symptom rather than the root cause, potentially creating new, unforeseen vulnerabilities. Effective and lasting corrective actions are developed based on the findings of the completed RCA, as seen in the CAPA process described in the clinical trial error analysis [3].References (research sources)

## 임상 시나리오

Clinical Application: Conducting a Root Cause Analysis (RCA)

Scenario

A nurse on a medical-surgical unit inadvertently administered Metoprolol 50 mg to the wrong patient. The patient, who had no history of cardiac issues, experienced bradycardia and hypotension, requiring monitoring and intervention. The nurse manager initiates a root cause analysis.

Prioritizing the RCA Process

The immediate priority is to assemble an interdisciplinary team to map the entire medication administration process and identify system failures and environmental factors. The goal is not to answer "who did it?" but "what in our system allowed this to happen?"

- **Focus on System Failures:** Investigate look-alike/sound-alike drug packaging, unclear patient identification bands, interruptions during medication preparation, and the layout of the medication room.

- **Analyze Environmental Factors:** Assess staffing ratios at the time of the error, noise levels, lighting, and the availability of barcode scanning technology.

- **Distinguish Error Types:** Apply a Just Culture framework. Was this a simple human slip (e.g., a momentary lapse in concentration due to fatigue), at-risk behavior (e.g., routinely bypassing a safety scan to save time), or reckless conduct? The response to each is different, focusing on system redesign, coaching, or disciplinary action, respectively.

Actions to Defer

The following actions are important but are not the priority during the initial RCA process:

- **Individual Blame:** Immediately identifying and documenting disciplinary actions for the staff member undermines the psychological safety needed for an honest investigation and prevents the discovery of latent system flaws.

- **Determining Patient Harm:** A clinical assessment of the patient to determine the extent of harm is a critical part of the *immediate response* to the error, but it is a separate, parallel process from the RCA's analytical focus on causation.

- **Premature Policy Changes:** Implementing immediate policy changes without a completed RCA often results in a "knee-jerk" reaction that fails to address the true root cause and may introduce new, unintended risks.

Key Takeaway

An effective RCA shifts the focus from a punitive, person-centered approach to a preventive, system-centered one. By identifying and redesigning flawed processes, the manager creates a safer environment for both patients and staff, embodying the principles of a high-reliability organization.

## 핵심 개념

- **Root Cause Analysis** — A problem-solving method that systematically identifies the fundamental systemic and procedural causes of an adverse event, rather than its superficial causes. It focuses on system improvement rather than individual blame.
- **Just Culture** — An organizational culture that emphasizes fair distribution of responsibility rather than blame. It distinguishes between intentional violations or reckless behavior and system design flaws or human error.
- **System Failure** — Problems arising from flaws in work processes, design, management decisions, organizational culture, etc., rather than individual mistakes. The primary subject of analysis in RCA.
- **Medication Error** — Preventable events that may occur during the prescribing, dispensing, administering, and monitoring of medications. Includes violations of the five rights of medication administration (right patient, drug, dose, route, time).
- **LASA (Look-Alike, Sound-Alike) Drugs** — Drugs that are easily confused due to similar names or appearances. This is one of the common systemic causes of medication errors.
