Clinical research on the effectiveness of health IT has mostly focused on clinical decision support and computerized physician order entry, and few of the other functionalities required to attest to meaningful use, according to ONC-funded research in Annals of Internal Medicine.
Researchers performed a literature review of 236 studies related to the quality, safety or efficiency of health IT. They found 57 percent of the literature focused on CDS or CPOE, while 12 of the remaining 23 meaningful use functionalities were not evaluated in any of the studies.
"The summary data show that CDS and CPOE have been studied extensively, and other functionalities, such as health information exchange and functionalities that allow patients to access their own electronic records, are not as well-studied," wrote the study authors. The authors suggest future research focus on more aspects of health IT and how they can be successfully implemented.
