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

Abstract

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.
