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)
Health information professionals recognize the need to demonstrate that the benefits of health information technological (HIT) interventions outweigh their costs. However, such cost-benefit analyses are rarely conducted for HIT interventions, due in part to the lack of a standard methodology. In this study, we describe how the U.S. Public Health Service's(More)
This study describes a framework for conducting economic analyses for health information technology (HIT) interventions, in the context of three interventions that are currently being implemented in a community-based health network caring for 17,779 Medicaid beneficiaries in Durham County, North Carolina. We show that if the HIT interventions were to(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)
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.

Subjects were randomized to receive intervention (email notifications for sentinel health events sent to(More)
