Here's something that technology has unfortunately made way too easy. A nephrologist is settling back in to the office after a short vacation and absentmindedly okays an e-Rx without actually verifying it. He doesn't notice that the Rx was mistakenly entered into the computer at a lethally high dose.

The patient dies.

... The physician tried to explain it to the attorney. “The way that I pulled up the email, the actual prescription information didn't show… so I didn't actually see the text,” he explained.
“But by clicking on the signature box you were effectively signing off on the prescription,” said the attorney. “This is problematic to defend. [It] would likely be considered by a jury to be below the standard of care owed to your patient.”
After careful consideration, the case was settled out of court for an amount within Dr. P's insurance coverage.
