Emergency care often determines the patient outcome as it is critical to make accurate, timely diagnoses and interventions during the early stages of the injury or disease. The Strategies to Innovate Emergency Care Clinical Trials Network (SIREN) was created by the NIH to enable the investigation of different emergency care treatments spanning across organ systems and diseases without duplication of effort, thereby minimizing start- up costs and promoting economies of scale. The purpose of the Data Coordinating Center (DCC) for SIREN is to provide a comprehensive data management and statistical infrastructure to support the network’s goal of conducting high quality clinical trials that will improve outcomes for patients with neurologic, cardiac, respiratory, hematologic and trauma emergency events. This renewal application, in response to RFA-NS-22-013, describes the features, functions and coordination we will continue to provide as the DCC for the SIREN Network. The DCC’s role is to establish a collaborative relationship with all parties involved in the Network and provide efficient and standardized central data management that yields high quality data, provide statistical support in the planning and execution of the clinical trials, prepare and disseminate trial reports for the various stakeholders and facilitate data sharing. To this end, the Data Coordination Unit (DCU) at the Medical University of South Carolina has developed a web-based comprehensive integrated data and project management system, WebDCU™, that enables distributed data entry from the participating clinical sites with extensive data quality control. The DCU also provides the necessary tools to efficiently manage operational activities across multiple trials, while ensuring compliance with FDA regulations and guidelines. Using the WebDCU system, we have developed, implemented and maintained a central database that streamlines and maximizes efficiency in the management of data collection, processing, and monitoring of clinical data. In addition, the WebDCU™ incorporates trial management information that provides full support for all study operational activities in SIREN. In collaboration with the individual study Principal Investigator and our partners of SIREN (CCC, Hubs, Governance Committees), the DCU will continue to: contribute to the innovative and efficient protocol development (including study design and case report form development); oversee data quality; generate reports for the DSMB, regulatory parties and the study teams; conduct interim and final analysis and dissemination of study results via presentations and publications; and create public use datasets for data sharing. SIREN initiated 5 large, simple multicenter trials over the previous 5 year grant period and will initiate at least 4 more in the next grant period. The network aims to transform the emergency research enterprise, by exploring innovations in clinical trial designs, by better and earlier engage...
