Difficulty: MediumPatient Safety and Quality Improvement

A 74-year-old woman is admitted to the medical ward for an acute exacerbation of chronic obstructive pulmonary disease. On her second day of hospitalization, the attending physician prescribes a tapering dose of oral prednisone. The patient's assigned nurse, who is working an unexpected double shift due to acute staffing shortages, misinterprets the electronic medication administration record. The nurse mistakenly administers 50 mg of oral dexamethasone instead of the prescribed 50 mg of prednisone. Over the next 24 hours, the patient develops severe hyperglycemia and delirium, necessitating transfer to the intensive care unit for a continuous insulin infusion. An incident report is submitted to the clinical safety department. Which of the following is the most appropriate initial action in response to this event?

  1. Convene an interprofessional group to analyze the underlying systems factors contributing to the incident.Answer
  2. B
    Restrict the involved nurse from clinical duties pending a formal review of professional competence.
  3. C
    Require the ward nursing staff to attend a mandatory educational seminar on corticosteroid pharmacology.
  4. D
    Institute a facility-wide protocol requiring two clinicians to independently verify all high-alert medications.
  5. E
    File a formal complaint against the nurse with the state nursing regulatory board for gross negligence.

Answer

The most appropriate initial action is to convene an interprofessional group to analyze the underlying systems factors contributing to the incident.
This event describes a serious medical error resulting in patient harm, triggering the need for a formal Root Cause Analysis (RCA). The core tenet of modern patient safety is the 'just culture' model, which recognizes that individual mistakes are typically the end result of latent system vulnerabilities (e.g., understaffing, fatigue, confusing electronic interfaces). Therefore, the immediate first step of an RCA is to convene a multidisciplinary team—including those directly involved in the event—to collect data, establish a timeline, and systematically analyze the contributing factors. Implementing solutions or punishing individuals before this analysis is complete is contrary to established quality improvement principles.

Step-by-Step Solution

1
Identify the nature of the event.
A sentinel event has occurred involving a medication administration error leading to severe patient harm and ICU transfer.
Categorizing the severity of the event dictates the required institutional response.
2
Determine the appropriate quality improvement framework.
A retrospective Root Cause Analysis (RCA) is indicated.
RCA is the standard procedure for investigating adverse events that have already occurred, aiming to identify system vulnerabilities.
3
Identify the first procedural step of an RCA.
Form a multidisciplinary team.
Before analyzing data or implementing solutions, a team involving leadership and frontline staff must be assembled to accurately map the sequence of events.

Key Concept

The initial step of a Root Cause Analysis (RCA) is to assemble a multidisciplinary team to investigate the system-level factors contributing to an adverse event, rather than assigning individual blame.
