Walter Reed Army Medical Center (02/01/1997 - 03/01/1999) - Operations Research Analyst, Utilization Mgmt. Washington, District of Columbia United States

Duties: As operations research analyst, assisted hospital leadership in determining the impact of managed care practices. Utilization management is a process by which patterns of health care delivery are analyzed and modified to improve care and reduce costs. Utilization management is a constantly evolving process as new ideas and methods are tested, rejected or refined. Studies were aimed at determining the appropriateness of level of care at the medical center, utilizing scientific inquiry and analysis to assist decision-makers at the command level. The impact of managed care practices were evaluated by examining the relationships among such variables as case mix index, length of stay, re-admission rates and timeliness of therapeutic interventions. The medical centers increasingly rely on DOD information systems to integrate and support their business processes. Data quality problems lead to bad decisions, monetary losses, and other negative consequences for the military health care system. These information systems and the quality of the data they contain affect perceptions of the quality of care and services, and potentially jeopardize allocation of resources if not addressed. Anticipated and prevented data problems and continuously improved data quality by providing system-wide access of information to the command, providers, and administrators. This work was of major importance to the programs and operations of not only Walter Reed Army Medical Center, DeWitt Army Medical Center, and Kimbrough Health Clinic, but also had significant impact on vital DOD-wide health care information systems. DOD medicine went through massive changes as congress mandated convergence of Navy, Army and Air Force hospital resources, as well as adoption of standard of care practices. Helped gather data to support these missions, as well as automate the many routine tasks required by clinical providers to maintain world-class healthcare for the soldiers and their families. Responsible for designing, building, and implementing a clinical database for Utilization Management InterQual data. Designed easy to use interfaces using a MS Access database so that UM nurses could automate clinical information gathering. Initiated an intranet Web site for Walter Reed by converting my workstation to a server. Designed Web pages for clinical and administrative staff to easily find reports, data, graphs, tables and presentations on the intranet. Integrated several data sources into the database, including the Retrospective Case-Mix Analysis System (RCMAS), Ambulatory Data System (ADS), the Corporate Executive Information System (CEIS), and the DOD Composite Healthcare System (CHCS). Determined the impact of changes in managed care practices using trend analysis, regression and analysis of variance.
