Is objective mobility data associated with pharmacologic venous thromboembolism (VTE) prophylaxis use among hospitalized older adults?

Analytic Interests.

1) Issues in the Design of Medical Experiments: I explore the use of reliability/generalizability models in experimental design. In addition to incorporation of reliability, I study powering longitudinal trials with multiple outcomes and substantial missing data using Mixed models.

2) Issues in the Analysis of Repeated Measures Designs & Longitudinal Data: Use of Hierarchical Linear Models (HLM) or Mixed Models in modeling trajectories of multiple variables over time (e.g., physical and cognitive functioning and Blood Pressure). My current work involves methodologies in simultaneous estimation of trajectories for multiple variables within and between domains, modeling co-occuring change.

Areas of Substantive interest: (1) Experimental design and analysis in gerontology and geriatrics, and psychiatry,
(2) Multivariate repeated measures designs,

Current research focuses on the epidemiology, prediction, and prevention of osteoporotic fractures in elderly persons, and in improving the quality of care delivered to residents in skilled nursing facilities. Ongoing projects include a large, administrative database study of osteoporosis screening in men, a randomized trial of different staff education strategies to improve fall prevention in nursing homes, and several clinical demonstration projects.

I am currently the Chief Medical Officer at Duke University Hospital. As CMO I am a member of the senior leadership team that positively impacts the strategies, goals, and objectives at our hospital. I also help support Duke Clinical Automated Laboratories in a clinical consultant role. I am a Professor of Medicine at Duke University. My faculty career track is as a Clinician Leader – Administrator with an emphasis on Clinical Practice Advancement. I have 25+ years of physician leadership experience with previous roles as Chief of Duke Hospital Medicine Programs and Associate CMO of Duke University Hospital. As a clinically active hospitalist, I actively teach learners as an attending physician for Duke Hospital General Medicine Teaching Services caring for patients at DUH and other venues. I am board certified by the American Board of Internal Medicine with a Focused Practice in Hospital Medicine, current in that board’s Maintenance of Certification Program, and have achieved the designation and recognition as a Senior Fellow in Hospital Medicine through the Society of Hospital Medicine. The themes of my scholarly output include readmissions reduction, venous thromboembolism risk in hospitalized older adults, physical activity in hospitalized older adults, mentorship programs for hospitalists, quality improvement teaching to residents, and hospitalist workflow improvements.

The general focus of Dr. Morey's work is exercise and aging. All of her research examines how physical activity, exercise training, or physical fitness influence the physical functioning and/or pyschosocial quality of life of older adults. She directs a supervised hospital-based program for older adults, which is used to examine longitudinally the effects of exercise training on the musculoskeletal, articular, and cardiorespiratory systems. Furthermore, she has a number of studies that examine how system-wide impairments serve as preclinical indicators of disability and overall decline in the quality of life of older adults. Ongoing studies examine the role of exercise training in attenuation or reversal of functional decline and examination of the effectivenes of different methods of physical activity counseling for home-based exercise.
Dr. Morey's research evolves directly from three sources: (1) primary analyses of clinical trials regarding the impact of exercise on a specific outcome, (2) longitudinal analyses of participants in ongoing clinical exercise programs, and (3) secondary analyses of clinical trials which involve exercise or physical activity.
Although physical activity and exercise are the interventions of interest in all of these studies, the outcomes of interest vary considerably. Within the broad domain of aging, Dr. Morey has examined the impact of exercise on physical performance, well-being, sleep quality, disability, and functional limitations. More recently, Dr. Morey has several studies focusing on the effect of tailored telephone physical activity counseling to improve function in elders. Specific studies are targeted to newly diagnosed cancer survivors, long-term cancer survivors, and frail elders in geriatric and primary care settings.
Dr. Morey's expertise is in the area of exercise physiology and aging. She has specific knowledge in age-related changes in cardiorespiratory functioning, the effects of habitual exercise (longitudinal) on performance, and exercise programming for older adults.
