What things does your lab do to reduce data entry errors? (i.e. test orders from paper requisitions, manually entered lab results, etc.) Most places I've worked simply have a 2nd person check the 1st person's work, but that's not a particularly reliable or time efficient strategy. Obviously eliminating the need for manual entry is the ideal solution, but everything can't be automated or computerized.
I'm also curious how your lab handles data entry errors when they are caught. Is there a punitive process? Retraining? Additional steps added to the process to try to prevent it from happening?
