Abstract
Background: A Delphi consensus was conducted to formulate an expert opinion on the definition of in-vitro fertilization (IVF) success, to provide a reference basis for clinical practice. Methods: Chinese experts in assisted reproductive technology (ART) were surveyed using the Delphi method. Based on the literature related to IVF success, eight experts developed a framework of statements and items. A questionnaire was then distributed to 23 experts to canvas their opinions on these statements. If consensus was not achieved, the statement was revised and revoted upon until a consensus was reached. Results: Consensus was reached for 19 statements related to the definition of IVF success, the most relevant of which are summarized as follows: (1) Goal of IVF treatment ([Formula: see text] statement): to attain a healthy live birth in the shortest possible time and with the lowest possible risks; (2) Definition of IVF success ([Formula: see text] statements): effectiveness, safety, and efficiency of IVF treatment should be included in the definition of success, with the cumulative live birth rate per ovarian stimulation cycle within 2 years being a performance indicator (PI) of success, and IVF success should be measured from a patient-centered perspective, including the patient’s burden and satisfaction. (3) Assurance of IVF success ([Formula: see text] statements): to provide evidence-based treatment and avoid the introduction of IVF add-ons into routine clinical practice without any clear evidence of benefit, optimize treatment quality by establishing and monitoring key PIs, and improving quality control systems. (4) Hurdles of IVF success ([Formula: see text] statements): cycle cancellation before oocyte pickup and treatment discontinuation after failed cycles are hurdles of success to IVF. Conclusions: Based on the Delphi method, the expert opinion on the definition of IVF success has been formed, which could complement guidelines and may help improve treatment outcomes.
