What initiated the fatal mistake in Frank Marshall's transfusion case?

The initiation of the fatal mistake in Frank Marshall's transfusion case was primarily due to the delivery of the wrong unit. This highlights the critical importance of proper labeling and verification processes in blood transfusions. When the incorrect blood unit is delivered, it poses severe risks to patient safety, such as transfusion reactions, which can be life-threatening.

In a healthcare setting, it is crucial that all blood products are accurately matched to the patient’s specific requirements. The protocols usually involve multiple checks to ensure that the blood type, Rh factor, and other vital information are thoroughly verified before transfusion. When the wrong unit is delivered, it bypasses these essential safety checks, leading to potentially catastrophic consequences.

This scenario emphasizes the need for robust systems and procedures to prevent such errors, along with the continuous training and awareness of medical staff regarding the critical nature of their role in ensuring patient safety during transfusions.
