For medical records, please see medical history.
Medical history was the history of the field of medicine.
In 2266, Dr. Leonard McCoy wryly noted, "In the long history of medicine, no doctor has ever caught the first few minutes of a play." (TOS: "The Conscience of the King")
In 2371, The Doctor explained his reasons for considering Pyong Ko as a name, saying that the 21st century surgeon's discovery of a genetic sequence that could inhibit the growth of cancer cells "heralded a new chapter in Earth's medical history." (VOY: "Fury")
In 2375, The Doctor chided a hologram of Crell Moset for being modest about his many accomplishemnts, noting that "You made medical history. You won the Legate's Crest of Valor." (VOY: "Nothing Human")
