What is the sensitivity of an ABC score of two or greater in predicting the need for massive blood transfusion?

The sensitivity of an ABC score of two or greater in predicting the need for massive blood transfusion is accurately represented by an option that reflects a higher percentage recognized in studies and clinical practice related to trauma and hemorrhagic shock management. Sensitivity measures the probability that the test accurately identifies individuals who need a massive blood transfusion.

A sensitivity of 75% means that if the ABC score is two or greater, there is a 75% chance that those patients indeed will require a massive blood transfusion. This level of sensitivity indicates that while the score is a useful indicator, it is not perfect, as a significant number of patients may still have a need for transfusion despite having a score below the threshold.

In medical practice, a higher sensitivity percentage contributes to better identification of at-risk patients, allowing for prompt and appropriate interventions. This makes the ABC score a valuable tool in triaging patients in emergency and trauma scenarios.
