Founded by Dr. Alexander Izaguirre in 2013, Aprenda Systems offers a cloud-based platform solution called Signature, which simplifies processes and minimizes administrative burdens for healthcare providers, administrators, payers, hospital systems, medical centers, and professional societies. Signature allows data owners to manage one master directory to supply their information simultaneously to multiple payers, medical systems, and professional societies, while data users can send an invitation to data owners requesting that they share their information through a custom profile that meets their specific data needs. Signature is secure, cloud-based, elegant, and comprehensive, so data is transferred in real time and provider information is always current. Signature is free for data owners to use, and saves data users substantial administrative time related to tracking down current provider information and obtaining attestations, among many other cost savings. With administrative costs accounting for 25% of our U.S. health care spend and growing, Signature is an easy, affordable solution to reducing health care costs, increasing patient and provider satisfaction, and eliminating administrative waste.
