Pathologists can get it right the first time.

It is established good practice for histopathologists to obtain a second opinion in difficult cases. However, it is becoming more common for histology material to be reviewed either at the time of reporting (double-reporting) or as part of the preparation for multidisciplinary team meetings. Routine histological review does not provide 'value for money' and could even increase the risk of diagnostic error. The focus should be on error prevention as opposed to error detection. If pathologists get it right the first time, then there would be less need for 'double checking'. Increased subspecialisation could increase diagnostic confidence and reduce error rates. Double-reporting and retrospective review should be limited to selected cases. We describe a protocol for clearly recording the process and outcome of such reviews.
