  Figure 1. Perceptions of (a) SSC risk and (b) severity of consequences by CV surgeons, for different types of CV surgery among survey respondents (N=50) Footnotes: Respondents were asked: “For each of the following cardiovascular surgery types, please indicate if they may be associated with higher likelihood of SSCs or more severe consequences of SSCs, compared with other types of surgery.” Abbreviations: CABG: coronary artery bypass grafting; CV: cardiovascular; ITAG: internal thoracic artery graft; SSC: surgical site complication; SVG: saphenous vein graft.

• 

  Figure 2. Perceptions of the importance of factors that contribute to SSC risk after CABG among survey respondents (N=50) Footnotes: Respondents were asked: “Please rate the importance of the following factors in contributing to the risk of a patient experiencing SSCs after CABG surgery.” Abbreviations: CABG: coronary artery bypass grafting; SSC: surgical site complication; SSI: surgical site infection.

• 

  Figure 3. Current practices for SSC prophylaxis after CABG among survey respondents (N=50) Footnotes: Respondents were asked: “Which of the following strategies do you currently use to prevent the occurrence of SSCs, including SSIs in your patients, after CABG surgery?” Abbreviations: CABG: coronary artery bypass grafting; NPWT: negative pressure wound therapy; SSC: surgical site complication.

• 

  Figure 4. Current use of prophylactic sNPWT after CABG and reasons for non-use among survey respondents (N=50) Footnotes: Respondents were asked: “Have you ever used sNPWT on closed surgical wounds after conventional CABG with open SVG/ITAG harvesting?” Abbreviations: AE: adverse event; CABG: coronary artery bypass grafting; sNPWT: single-use negative pressure wound therapy; SSC: surgical site complication.

• 

  Figure 5. Respondents’ expectations of benefits from sNPWT for SSC prophylaxis and ranking scores for the importance of each benefit among survey respondents (N=50) Footnotes: Respondents were asked: “What benefits do you expect in terms of SSC (including SSI) prevention from using sNPWT prophylactically on closed surgical incisions?” and “please rank the following factors in order of importance for the prophylactic use of sNPWT in the prevention of SSCs, including SSIs, in closed surgical incisions.” Maximum ranking score: 9.00. Abbreviations: SD: standard deviation; sNPWT: single-use negative pressure wound therapy; SSC: surgical site complication; SSC: surgical site infection.

  Figure 6. Respondent’s reporting of influential factors for non-use of prophylactic sNPWT after CABG among survey respondents (N=50) Footnotes: Respondents were asked: “Please rate the extent to which each of the following considerations has influenced your past decisions not to use sNPWT prophylactically on your patients’ closed wounds after conventional CABG surgery using open SVG/ITAG harvesting.” Abbreviations: sNPWT: single-use negative pressure wound therapy; CABG: coronary artery bypass grafting; SVG: saphenous vein graft; ITAG: internal thoracic artery graft

  Figure 7. Evidence needs to inform prophylactic sNPWT use after CABG among survey respondents (N=50) Footnote: Respondents were asked to select up to three for “what further clinical evidence would be valuable to inform your prophylactic use of sNPWT after CABG surgery to prevent SSCs, including SSIs?” Abbreviations: CABG: coronary artery bypass grafting; RCT: randomised controlled trial; RWE: real-world evidence, sNPWT: single-use negative pressure wound therapy.
