Objective: This study aims to develop a core information set (CIS) for induction of labour. A CIS is an agreed set of information points for discussion prior to an intervention. Design: First a long list of information points was identified through a systematic review of reviews, reviewing patient leaflets, analysis of pre-existing qualitative interviews and an initial stakeholder survey. A long list of items was collated before combining and refining alongside an involvement group. Cognitive interviews were undertaken to refine the Delphi Survey before a two-round modified Delphi process where participants voted on the importance of the information items. Pre-specified criteria were used to select the items taken forward to a consensus meeting. Participants were recruited via UK hospital sites, online and social media platforms and included parents and professionals. Setting and population: Participants were recruited via UK hospital sites, online and social media platforms and included parents and professionals. Main outcome: A core information set for induction of labour. Results: 199 information points were identified through systematic review (110), patient information leaflets (162), qualitative interviews (58) and a survey (93). 46 unique information items entered the first Delphi round after 4 cognitive interviews, 2 items were added following round 2. 368 people (310 parents/ 58 professionals) participated in round 1 and 177 people (154 parents/23 professionals) in round 2. 44 items met inclusion criteria; 1 item excluded, and 3 items were carried forward for consensus meeting discussion where 12 overarching information points were agreed upon. Conclusion: This CIS can help to inform and support discussions about induction to enable parents to make informed decisions about birth.
