BACKGROUND Despite a consensus that the use of health information technology should lead to more efficient, safer, and higher-quality care, there are no reliable estimates of the prevalence of adoption of electronic health records in U.S. hospitals. METHODS We surveyed all acute care hospitals that are members of the American Hospital Association for the(More)
BACKGROUND Electronic health records have the potential to improve the delivery of health care services. However, in the United States, physicians have been slow to adopt such systems.

Electronic health records (EHRs) are promising tools to improve quality and efficiency in health care, but data on their adoption rate are limited. We identified surveys on EHR adoption and assessed their quality. Although surveys returned widely different estimates of EHR use, when available information is limited to studies of high or medium quality,(More)
BACKGROUND Patients' perceptions of their care, especially in the hospital setting, are not well known. Data from the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey provide a portrait of patients' experiences in U.S. hospitals.

BACKGROUND Comprehensive knowledge about the level of healthcare information technology (HIT) adoption in the United States remains limited. We therefore performed a baseline assessment to address this knowledge gap. METHODS We segmented HIT into eight major stakeholder groups and identified major functionalities that should ideally exist for each,(More)
Understanding whether electronic health records, as currently adopted, improve quality and efficiency has important implications for how best to employ the estimated $20 billion in health information technology incentives authorized by the American Recovery and Reinvestment Act of 2009. We examined electronic health record adoption in U.S. hospitals and the(More)
Electronic clinical data exchange promises substantial financial and societal benefits, but it is unclear whether and when it will become widespread.

Only twenty efforts were of at(More)

Physicians worry these rankings will become an outlet for disgruntled patients. OBJECTIVE To describe trends in patients' online ratings over time, across specialties, to identify what physician(More)
OBJECTIVE Although computerized physician order entry (CPOE) may decrease errors and improve quality, hospital adoption has been slow. The high costs and limited data on financial benefits of CPOE systems are a major barrier to adoption. The authors assessed the costs and financial benefits of the CPOE system at Brigham and Women's Hospital over ten years.(More)
