The clinic-based healthcare model does not deliver high quality, cost-effective care to populations of patients. Despite public perception that aggressive investment in information technology will lead to improvements in the safety and quality of healthcare delivery, there is little evidence that health information technology can be used to promote(More)
Increasing emphasis is being placed on the importance of information technology to improve the safety and quality of healthcare. However, concern is growing that these potential benefits will not be equally distributed across the population because of a widening digital divide along racial and socioeconomic lines. In this pilot study, we surveyed 31(More)
Data collection from patients for use in clinical decision making is foundational for medical practice. Increasingly, kiosks are being used to facilitate direct data collection from patients. However, kiosk-collected data are generally not integrated into the care process. In this project, 4,014 people initiated a kiosk-administered health risk assessment(More)
Although evidence-based pharmacotherapies are a principal component of patient care, 30-50% of patients do not take their medications as prescribed. We conducted a randomized trial of two clinical decision support (CDS) interventions in 2219 patients: patient adherence reports to providers (n=744), patient adherence reports to providers + email notices to(More)
Governments are investing in health information technologies (HIT) to improve care quality and reduce medical costs. However, evidence of these benefits is limited. We conducted a randomized trial of three clinical decision support (CDS) interventions in 20,180 patients: email to care managers (n=3329), reports to primary care administrators (n=3368),(More)
To determine whether a clinical decision support system can favorably impact the delivery of emergency department and hospital services. Randomized clinical trial of three clinical decision support delivery modalities: email messages to care managers (email), printed reports to clinic administrators (report) and letters to patients (letter) conducted among(More)
BACKGROUND Replication studies evaluate technologies in usual use settings. METHODS We conducted a clinical trial to determine whether reductions in clinical and economic results observed in a previous study could be replicated in a larger setting. Subjects were randomized to receive intervention (email notifications for sentinel health events sent to(More)
Patient Internet portals that allow patients to access their personal health information are an emerging form of enabling technology. The purported benefits from increasing use of information technology in healthcare, however, may not be universal because of a widening digital divide along racial and socioeconomic lines. In this pilot study, we surveyed 31(More)
