However, these staged interventions are not consistently defined. Standardized definitions are needed to allow meaningful comparisons of this outcome among trials. This document provides guidance on relevant parameters involving staged procedures, including minimum data collection and consistent classification of coronary procedures initially identified as staged; the aim is to achieve consistency among clinical trialists, sponsors, health authorities, and regulators. Definitions were developed jointly among representatives of academic institutions and clinical research organizations based on clinical trial experience and published literature. Reasons for staged procedures were identified and include baseline kidney function, contrast load and radiation exposure, lesion complexity, and patient or operator fatigue. Moreover, nonclinical reasons include procedure scheduling and reimbursement. Management of staged procedures should be a standalone section in clinical trial protocols and clinical events committee charters. These documents should clearly define a time window for staged procedures that allows latitude for local policies, while respecting accepted clinical guidelines, and consistency with study objectives. Investigators should document in the case report form the intent to stage a procedure, the lesions to be treated, and the reasons for staging, preferably before randomization. Ideally, all reinterventions, or at least all procedures performed after the recommended time window, those in which data suggest an anticipated procedure due to a worsening condition and those where a revascularization is attempted in the target vessel, should be reviewed by an independent clinical events committee.Abstract: Copyright (c) 2018 American College of Cardiology Foundation.
