Medical log

A medical log is a form of log entry depicted by a medical officer. It serves as a record of medical cases for the officer's own benefit and that of future physicians.

Doctor Leonard McCoy kept medical logs during his service as chief medical officer of the USS Enterprise. His logs also contained personal thoughts or concerns on a situation or people. 

The Doctor of the USS Voyager also kept medical logs, including one in which he reported his conclusion that Chakotay was not the father of Seska's child. .

Starfleet Chief Medical Officers have the power to relieve Starfleet personnel from their duties, even a superior officer. They must log such actions in the official medical log and must have proper medical documentation or the support of one senior command officer to justify such removal. All of this must be noted in the medical log.
