Studies have also demonstrated that if the endoscopists aware of being monitored they might increase their CWT (the Hawthorne effect). The bowel cancer screening program actively monitors the CWT of endoscopists to ensure that all colonoscopies are of adequate quality but non-screening colonoscopies are… Show more
