CORESS is an independent educational service that promotes safety in surgery across all specialties. The CORESS system relies on voluntary reports of adverse incidents or near misses from surgical practice submitted anonymously. These anonymized reports are published with the aim of highlighting potential issues to surgeons and surgical teams to improve safety. The program director and board of directors of CORESS acknowledged Richard Sennett for providing material considered for publication in the CORESS bulletin in the latest issue from May 2015.
