Letter: NHS charges

Sir: Most doctors, Polly Toynbee says, "haven't a clue how they are doing", with "little idea what their own success rates are", as if patients, once treated or operated on are never seen again. Apart from follow-up of individual cases, often for several years, surgical departments also have regular audit sessions, with emphasis on discussing morbidity and mortality. Audit is considered an essential part of surgical training, and all trainees are required to keep a log book.
