SchoolCare delivers free health technology for K-12 public schools to help school nurses deliver care and keep students safe. It is a digital health platform for the largest and most consistent health delivery system in the country. Their mission is to work with partners to provide a unified health record for every family. SchoolCare leveragespediatric health data and this country’s most successful public health organization, the K-12 school system, to improve outcomes and learn about clinical health data outside of the provider’s office. Traditional care coordination stops short of sending essential care instructions to School Nurses and thus increases the risk of stopped or inconsistent post-discharge care delivery. By closing the link in the pediatric care continuum, children stay healthy and get better faster. | $24.3M / Series C / Feb 15, 2019 | |
