Background Electronic health records have the potential to improvethe delivery of health care services. However, in the UnitedStates, physicians have been slow to adopt such systems. Thisstudy assessed physicians' adoption of outpatient electronichealth records, their satisfaction with such systems, the perceivedeffect of the systems on the quality of care, and the perceivedbarriers to adoption.
Methods In late 2007 and early 2008, we conducted a nationalsurvey of 2758 physicians, which represented a response rateof 62%. Using a definition for electronic health records thatwas based on expert consensus, we determined the proportionof physicians who were using such records in an office settingand the relationship between adoption and the characteristicsof individual physicians and their practices.
Results Four percent of physicians reported having an extensive,fully functional electronic-records system, and 13% reportedhaving a basic system. In multivariate analyses, primary carephysicians and those practicing in large groups, in hospitalsor medical centers, and in the western region of the UnitedStates were more likely to use electronic health records. Physiciansreported positive effects of these systems on several dimensionsof quality of care and high levels of satisfaction. Financialbarriers were viewed as having the greatest effect on decisionsabout the adoption of electronic health records.
Conclusions Physicians who use electronic health records believesuch systems improve the quality of care and are generally satisfiedwith the systems. However, as of early 2008, electronic systemshad been adopted by only a small minority of U.S. physicians,who may differ from later adopters of these systems.
