It’s been a few years, four to be exact, since NaviHealth announced an acquisition. The silence was broken in late February, when it acquired Innovative Healthcare Delivery (IHD). The deal is part of NaviHealth’s mission to extend non-clinical services into seniors homes. Financial terms were not disclosed.

IHD, based in Henderson, Nevada, specializes in identifying and addressing social determinants of health to improve quality of life and clinical outcomes for patients. It delivers a high-touch, patient-centric and non-clinical approach that is paired with proprietary workflow and patient engagement technology to address barriers and improve efficiences to get the right care at the right time.

The company connects directly with patients to ensure they understand and are able to follow critical care guidance such as discharge instructions, medication adherence and attendence at follow-up appointments. NaviHealth expects this deal will expand its care services from post-acute care into the home.

NaviHealth is now majority-owned by Clayton, Dublier & Rice. It partners with the nation’s top health plans, health systems, physician groups and post-acute providers to manage the entire continuum of care. Cardinal Health (NYSE: CAH) bought the firm from Welsh, Carson, Anderson & Stowe in August 2015 for $290 million. At that time, NaviHealth offered software and anaytics products focused on managing post-acute care bundled payments.

Almost immediately, Cardinal Health began adding to NaviHealth’s capabilities. In December 2015, it acquired RightCare Solutions, a discharge decision support platform that reduces readmissions for hospitals and health systems. In April the following year, Curaspan Health Group came aboard. Curaspan provides care transition tools for hospitals and post-acute healthcare providers. Financial terms weren’t disclosed in those deals, either.
