Designing and testing computer based screening engine for severe sepsis/septic shock.
This study addresses the role of a sepsis "sniffer", an automatic screening tool for the timely identification of patients with severe sepsis/septic shock, based electronic medical records. During the two months prospective implementation in a medical intensive care unit, 37 of 320 consecutive patients developed severe sepsis/septic shock. The sniffer demonstrated a sensitivity of 48% and specificity of 86%, and positive predictive value 32%. Further improvements are needed prior to the implementation of sepsis sniffer in clinical practice and research.

Promoting adherence to ventilator management and ventilator weaning protocols.
Studies have shown that ventilator weaning protocols have resulted in a reduction in duration of mechanical ventilation, ventilator-associated pneumonia, and the rate of re-intubation when compared to weaning directed by a physician. This project continuously monitors weaning status and provides feedback on each patients status. The specific aim of this project is to improve the adherence to ventilator management and ventilator weaning protocols.

Developing a novel Internet-based psychoeducational intervention for dementia caregivers.
DementiaCareCentral.com is a new online intervention for family caregivers of individuals with Alzheimer's disease and other dementias. The website includes a combination of educational information, psychosocial and peer support tools, and interactive resources. The website is being developed with feedback obtained from dementia caregivers in several rounds of needs analysis and usability evaluation.

Engineering of a clinical decision support framework for the point of care use.
Computerized decision support for use at the point of care has to be comprehensive. It means that clinical information stored in electronic health records needs to be integrated with various forms of clinical knowledge (elicited from experts, discovered from data or summarized in systematic reviews of clinical trials). ⋯ Then we applied the process to build MET-A3Support. The paper describes the engineering process and its results, including models representing selected elements of our framework.

Clinical trials in silico: rigorous assessment of treatment effect using electronic health records.
With their ability to balance measured and unmeasured confounders, randomized controlled trials (RCTs) provide the highest level of evidence regarding the effect of treatment. Analyses of administrative data have had inconsistent success when compared with the results of RCTs. ⋯ The comprehensive, longitudinal data within Electronic Health Records (EHRs) can overcome the data quality issues. This report describes a new analytical method for EHR data that successfully replicates RCT results.
