A modified Delphi process to form an expert consensus in Ireland on the essential information to be included in shared decision making for varicose vein surgery.

Objective: To reach consensus on a core set of essential information for inclusion in the informed consent process to standardize consent for VV surgery.

Methods: Using a modified electronic Delphi (e-Delphi) method, a panel of experts in Ireland, were asked to rate statements of essential information to include in the informed consent process with patients. Statements were rated using a 5-point Likert scale. The definition of consensus was declared at 70% agreement by the panel.

Results: Twenty-three panel members accepted the invitation to participate across three e-Delphi rounds. Consensus was reached on 33/42 statements, covering general and procedural information and the risks, benefits and alternatives of varicose veins (VV) surgery. Several statements remained equivocal, having not met consensus by the panel.

Conclusion: Considerable consensus was reached within the panel of experts but some gaps in available research were also highlighted. This consensus may provide the framework to aid physicians to deliver a standardized discussion of the key elements of consent and shared decision making with patients.
