Optimizing healthcare delivery--improving processes to reduce impediments to care--is an important goal of the Military Health System. Models and data can be effective tools to assist managers in achieving this goal. This paper illustrates this utility with a case study of the intensive care unit (ICU) at the US Air Force's Wilford Hall Medical Center. A(More)
BACKGROUND Although congestive heart failure (CHF) is a primary target for disease management programs, previous studies have generated mixed results regarding the effectiveness and cost savings of disease management when applied to CHF. OBJECTIVE We estimated the long-term impact of systolic heart failure disease management from the results of an(More)
We used discrete-event simulation to help the San Antonio public health and acute medical care communities to plan their response to a bioterrorist attack. The analysis, based on a scenario positing an attack with aerosolized smallpox, indicated the resources and strategies needed for an effective response. We found that a mixture of public-health measures(More)
This study extends nutritional intervention results reported by short-term clinical trials of a diabetes-specific nutritional meal replacement by assessing the ten-year impact of the interventions on patient outcomes and costs compared to usual care. We developed and validated a computer simulation of type 2 diabetes based on published data from major(More)
OBJECTIVE To describe the results of a simulation study of the spread of pandemic influenza, the effects of public health measures on the simulated pandemic, and the resultant adequacy of the surge capacity of the hospital infrastructure and to investigate the adequacy of key elements of the national pandemic influenza plan to reduce the overall attack rate(More)
Objectives: This paper demonstrates the applicability of discrete event simulation to planning the response of a rural acute health-care delivery system to a bioterrorist attack. Simulation results are used to develop observations and recommendations for planning for bioterrorism events in rural settings. Method: The analysis employed two discrete event(More)
