A 4-month-old infant in the pediatric intensive care unit requires a continuous intravenous heparin infusion. Due to a stocking error in the automated dispensing cabinet, a highly concentrated adult preparation of heparin is inadvertently retrieved and administered. The infant develops significant bleeding but is successfully stabilized following the administration of protamine and supportive care. The hospital's risk management department determines that this sentinel event requires a formal investigation. As the chief resident involved in quality improvement, you are tasked with outlining the standard investigative process. Arrange the following steps of the formal root cause analysis in the correct chronological sequence.
- 1Impound the involved infusion pump, intravenous tubing, and medication vials.
- 2Assemble a multidisciplinary team of stakeholders and subject matter experts.
- 3Map out a chronological timeline of the events preceding the incident.
- 4Utilize analytical tools to distinguish latent system vulnerabilities from active errors.
- 5Design and deploy targeted systems-level interventions, such as forcing functions.
Cevap
The correct sequence is to first secure the physical evidence, then form a multidisciplinary team, map out the timeline of events, analyze the root causes using specific tools, and finally design and implement targeted interventions.
The correct chronological sequence for a formal Root Cause Analysis (RCA) begins with securing the physical evidence and data immediately after the patient is stabilized. Once the evidence is preserved, a multidisciplinary team is formed to ensure a comprehensive, unbiased review. This team first gathers data to construct an accurate chronological timeline of events to clearly understand exactly what occurred. Only after the timeline is established does the team analyze the sequence using tools like the 'Five Whys' to identify root causes and latent systems vulnerabilities. Finally, the team uses these findings to design and implement corrective action plans, such as forcing functions, to prevent recurrence.
