The document discusses requirements, applications, technology, and research related to enterprise application integration in healthcare. It provides examples of healthcare applications that have used the METEOR EAppS (Enterprise Application Suite of Services and Tools), including neonatal clinical pathways, genome sequencing, eligibility-referral, and immunization tracking. It also discusses requirements for mission-critical healthcare applications and the state of technology, products, and research in areas like workflow management and enterprise application integration.
