Despite benefits associated with the use of electronic health records (EHRs), one major barrier to adoption is the concern that EHRs may take longer for physicians to use than paper-based systems. To address this issue, we performed a time-motion study in five primary care clinics. Twenty physicians were observed and specific activities were timed during a(More)
BACKGROUND Electronic health records (EHRs) allow for a variety of functions, ranging from visit documentation to laboratory test ordering, but little is known about physicians' actual use of these functions. METHODS We surveyed a random sample of 1884 physicians in Massachusetts by mail and assessed availability and use of EHR functions, predictors of(More)
BACKGROUND Health maintenance is crucial for preventing morbidity and premature mortality, but many patients do not receive preventive services at recommended intervals. One reason for this is the lack of up-to-date information accurately reflecting patients' history. Electronic health records (EHRs) can be useful, but are often incomplete. Patient input(More)
The effectiveness of electronic health record (EHR)-based clinical decision support is limited when clinicians do not interact with the EHR during patient visits. To assess EHR use during ambulatory visits and determine barriers to such use, we performed a cross-sectional survey of 501 primary care clinicians. Of 225 respondents, 53 (24%) never or only(More)
BACKGROUND Web-based personal health records (PHRs) have been advocated as a means to improve type 2 diabetes mellitus (DM) care. However, few Web-based systems are linked directly to the electronic medical record (EMR) used by physicians. METHODS We randomized 11 primary care practices. Intervention practices received access to a DM-specific PHR that(More)
OBJECTIVE To assess physicians' attitudes toward health information exchange (HIE) and physicians' willingness to pay to participate in HIE. DESIGN We conducted a cross-sectional mail survey of 1296 licensed physicians (77% response rate) in Massachusetts in 2007. MEASUREMENTS Perceptions of the potential effects of HIE on healthcare costs, quality of(More)
BACKGROUND Despite the availability of expert guidelines and widespread diabetes quality improvement efforts, care of patients with diabetes remains suboptimal. Two key barriers to care that may be amenable to informatics-based interventions include (1) lack of patient engagement with therapeutic care plans and (2) lack of medication adjustment by(More)
OBJECTIVES We studied how health information exchange systems are established by examining the decisions (and thus, indirectly, the values) of key stakeholders (health care providers) participating in a health information exchange pilot project in 3 Massachusetts communities. Our aim was to understand how these kinds of information exchanges can be made(More)
BACKGROUND: The ability to electronically exchange health information among healthcare providers holds enormous promise to improve care coordination and reduce costs. Provider-to-provider data exchange is an explicit goal of the American Recovery and Reinvestment Act of 2009 and may be essential for the long-term success of the Affordable Care Act of 2010.(More)
BACKGROUND Limited data exist to estimate the use of electronic health records (EHRs) in ambulatory care practices in the United States. METHODS We surveyed a stratified random sample of 1829 office practices in Massachusetts in 2005. The one-page survey measured use of health information technology, plans for EHR adoption and perceived barriers to(More)
