SironaHealth

SironaHealth was a U.S. healthcare services and technology company focused on outsourced telehealth, nurse triage, clinical care coordination, and patient engagement for health plans, hospitals, providers, and other healthcare organizations. Its offerings included nurse advice lines, ER decision support, preventive care reminders, pre-admission services, post-discharge follow-up, and physician referral and appointment support. The company appears to have operated as a commercial healthcare services business rather than a drug developer, with proprietary call-center and patient engagement technology supporting population health and care management workflows. SironaHealth was acquired by Citra Health Solutions in March 2016 and subsequently operated as part of Citra, so it is best treated as a closed standalone company rather than an active independent business.
