Please note: This is a Sole Source Notification. This is notice of intent to award a contract as a sole economically feasible source to: ESi Acquisition, Inc. for software and services for the ESAR VHP volunteer registration software. The Emergency System of Advance Registration (ESAR) is a customized software program from ESi Acquisitions, Inc. that is a comprehensive volunteer management and engagement solution with a built-in background check, credential verification, mission management, badging, and notification capabilities specifically designed to meet the Federal ESAR-VHP (Emergency System for Advance Registration of Volunteer Health Professional) requirements. ESAR-VHP software program has been customized to integrate with the existing Illinois emergency response infrastructure software programs. The ESAR-VHP registry platform is currently in use with over 40 states, including all IL border states (WI, MI, MO, IA, IN, KY), which will facilitate and greatly enhance critical cross-border communications and information sharing. They also provide on-site training and upgrades to the site quarterly at no extra cost and perform their maintenance as a vendor-hosted system. Having this system will ensure the usefulness of the existing software programs. With this system, IDPH will retain federal funding, as having this ability is federally mandated.
