Question 83

Perform a root-cause analysis (RCA).

To address the serious harm caused to a patient due to an error, the pharmacy staff should conduct a root-cause analysis (RCA) to identify the underlying factors that contributed to the incident and prevent future occurrences.

A) failure mode and effects analysis (FMEA)

While FMEA is a proactive tool used to anticipate potential failures and their effects before they occur, it is not suitable for addressing an error that has already caused patient harm. The situation requires a retrospective investigation to analyze what went wrong, which is the primary function of RCA.

B) medication reconciliation

Medication reconciliation is a process aimed at ensuring accurate medication lists for patients during transitions in care to prevent errors. However, it does not investigate the root causes of an error that has already occurred. Therefore, it is not the most appropriate response in this context.

C) therapeutic substitution

Therapeutic substitution refers to replacing a prescribed medication with a different drug that has similar therapeutic effects. This option is not relevant to understanding the cause of an error that has already harmed a patient and does not address the need for analysis of the incident.

D) root-cause analysis (RCA)

RCA is the most appropriate choice because it involves systematically identifying the fundamental issues that led to the error. This method allows pharmacy staff to learn from the incident and implement changes to improve safety and quality of care.

Conclusion

Conducting a root-cause analysis (RCA) is essential for understanding the factors that led to the patient harm and for developing strategies to prevent similar errors in the future. Options A, B, and C do not effectively address the need for a thorough investigation and understanding of the error's origin, making RCA the definitive and most suitable choice.
