The study explores why hospitals have chosen to embrace or eschew ICU telemedicinetrademarked as eICU by the dominant vendor VISICU Inc.finding that "hospital clinical leaders hold strong views but have little objective information on which to judge the worthiness of this innovation," according to the study funded by the Robert Wood Johnson Foundation.
"The rapid diffusion of eICUs in hospitals across the country, which remains largely unstudied, illustrates the need for comparative effectiveness initiatives to include innovations in how we care for patients-not just specific drugs, devices and services," said HSC Senior Consulting Researcher Robert A. Berenson, M.D., also an institute fellow at the Urban Institute, and co-author of the study with HSC Senior Researcher Joy M. Grossman, Ph.D., and Elizabeth November, J.D., an HSC health research analyst.
"Proponents and detractors of eICUs feel strongly that their assessments are correct," Berenson added. "But without a rigorous assessment, who knows which side is right?"
The Health Affairs article, titled "Does Telemonitoring of PatientsThe eICUImprove Intensive Care?" was a follow-up study from HSCs 2007 site visits to 12 nationally representative communities-Boston; Cleveland; Greenville, S.C.; Indianapolis; Lansing, Mich.; Little Rock, Ark.; Miami; northern New Jersey; Orange County, Calif.; Phoenix; Seattle; and Syracuse, N.Y. HSC has been tracking change in these markets since 1995.
During the 2007 site visits, HSC researchers learned that hospital systems in fiveIndianapolis, Little Rock, Miami, Phoenix and Seattleof the 12 communities had adopted eICU systems. In the follow-up study, researchers interviewed clinicians in the five hospital systems with an eICU, clinicians in 19 non-eICU hospitals in the 12 markets, and national experts on ICU staffing, quality and ICU telemedicine.
The eICU system combines the use of telemedicine with software applications to manage ICU patients from a central monitoring station, usually located off-site from the actual ICU and staffed with physicians with advanced training in critical care known as intensivists, critical care nurses and administrative personnel.
