Need some feedback on what others do when confronted with a consent that needs to be corrected. We have had several episodes where the surgical consent was signed by the patient during the preadmission visit but when the chart is reviewed prior to being sent to the Preop unit for admission, an error is discovered (missed word, transposed diagnosis and procedure, seriously misspelled words affecting the meaning). The patient is no longer available at this point.
We are having a debate on what to do with the signed consent that's on the chart. The debate is whether it's best to remove the incorrect consent and throw it out or leave it on the chart and have a new one signed when the patient arrives. We have checked with risk management - got no definitive answer.

Options for leaving it in place include putting a post-it note on the consent with a note to correct (could fall off), placing a large red X across the form, etc. What does everyone else do in this situation?
Any feedback would be appreciated.
