Supplementary Material

Following systematic literature review of the published literature over the last 10 years, all relevant papers were coded into categories based on the identified areas of uncertainty in the management of DCIS. The salient research areas that were identified are shown in Supplementary online appendix 1. A process of cognitive interviewing finalised the optimal question phrasing and survey structure. A sample of the final survey distributed to surgeons is shown in supplementary online appendix 2. More detailed analyses of responses to the survey by monthly workload (number of operations undertaken by the respondent per month) are shown in supplementary online appendices 3 and 4. Supplementary online appendix 5 shows a tabulation of how differences in seniority and region influence concordance of respondents’ survey answers with NICE guidelines regarding the role of SLNB in DCIS.
