Evidence is needed to justify whether investment in an internationally agreed core outcome set for inguinal hernia surgery is needed. This study aimed to assess outcome reporting from randomised controlled trials (RCTs) and meta-analyses in inguinal hernia surgery. ⋯ Outcome reporting from RCTs concerning inguinal hernia repair is inconsistent and poorly defined, limiting meta-analyses, which themselves do not control for the differing definitions of assessed outcomes. This study justifies investment in a standardised core outcome set for inguinal hernia surgery, to improve outcome reporting and evidence synthesis.
