BLEEDING TIME: IS IT A USEFUL CLINICAL TOOL?

The bleeding times of five volunteers were assessed individually by each of 12 observers. The reliability of the measurements obtained was examined by comparing statistically the variability between subjects and between observers. This variability was found to be similar for both groups.

Description
Summary:The bleeding times of five volunteers were assessed individually by each of 12 observers. The reliability of the measurements obtained was examined by comparing statistically the variability between subjects and between observers. This variability was found to be similar for both groups. Consequently, we suggest that the bleeding time estimation is an unreliable test and should not be used in isolation without reference to the salient features of a history and examination, when determining if an individual patient is at risk of haematoma formation as a complication of regional anaesthetic techniques.
