Founded in 2002 and based in Carlsbad, Calif., Medsphere’s CareVue solution is an acute and inpatient behavioral health-oriented portfolio of clinical products and services. The Medsphere team sees the patient as the ultimate beneficiary of broadly adopted healthcare IT. Ultimately, a fully interoperable, nationwide healthcare IT system enables better patient care and gives America a leg up on chronic social problems like substance abuse and homelessness. We cannot succeed in realizing the goal of quality care for all citizens by keeping data in silos and failing to enable communication among disparate systems.

With these goals in mind, Medsphere has recently expanded to incorporate solutions that meet the needs of healthcare providers across the continuum of care.
