Biostatistics, Design and Analysis

DescriptionContactMeeting Occurrence
The Center on Aging and Health provides cutting-edge statistical and research design expertise in collaboration with other investigators in aging research. Our biostatistics and methodological experts are internationally known for their accomplishments in developing new methods for testing complex hypotheses and models. The recent establishment of a 'cold room' for Medicare calims analyses and other sensitive health data has expanded the Center's analytic capabilities and infrastructure.Jing Tian, MS

2nd and 4th Monday

2:00 p.m. - 3:00 p.m.


Cognitive and Sensory Functions

DescriptionContactMeeting Occurrence
We are seeking to better identify preclinical markers of cognitive decline and to evaluate risk modifiers of cognitive functional aging and dementia risk. Through both observational research and intervention studies, we are characterizing trajectories of cognitive aging and exploring the impact that community-based interventions have on older adults' cognitive functions and brain plasticity. Our research on sensory functions includes groundbreaking studies on hearing loss, a problem that is untreated in a large majority of affected individuals. In one study of over 600 patients, we found a link between hearing loss and subsequent onset of dementia over a 12-year period. Hearing loss might also contribute to social isolation, which further increases risk for cognitive decline.Alden Gross, PhD

Last Tuesday of the month

2:00 p.m - 3:00 p.m. EST


Family and Social Resources

DescriptionContactMeeting Occurrence
Most older adults rely on family members, neighbors, or friends to help them manage their health problems and maximize function.A unifying theme of the Johns Hopkins Roybal Center for Translational Research is an emphasis on better understanding and strengthening the family and social support resources of vulnerable older adults, particularly those with physical or cognitive impairments.The Roybal Center funds pilot studies that address family and social support resources such as caregiving across a diverse set of clinical conditions including dementia, stroke, end stage renal disease, and multiple chronic conditions.Laura Samuel, PhD, CRNP

Every 4th Tuesday

1:00 p.m - 2:00 p.m. EST


Frailty and Multisystem Dysregulation

DescriptionContactMeeting Occurrence
An integral part of our research mission is to identify the causes of and treatments for frailty, an age-related condition characterized by reduced strength, energy, and activity. The Johns Hopkins Older Americans Independence Center (OAIC) supports a broad range of population-based, biological, and clinical studies on frailty etiology, management, and prevention.  The OAIC  provides important resources for pilot studies and for career development of emerging scholars.Brian Buta, MHS

Every 4th Wednesday

9:00 a.m - 10:00 a.m. EST


Linked Administrative Data Resource (LADR)

DescriptionContactMeeting Occurrence
As healthcare costs continue to rise, the study of healthcare utilization is critical to identifying inefficiencies in resource allocation as well as potential cost savings. Outcomes that are important to patients such as function and quality of life are often not captured in traditional insurance databases, and specific healthcare utilization measures such as the number of days spent in hospital or emergency department visits are often poorly captured in epidemiologic survey studies. As part of its ongoing commitment to innovate and explore new avenues to advance research in aging the Center has recently set up a secure “cold room” designed to house highly restricted sensitive data that could address important new research questions around healthcare utilization. Linking separate sources of sensitive data such as Medicare claims data and longitudinal epidemiologic studies of aging and health allows researchers to answer important research questions in a way that would not be possible using either source on its own. The Medicare claims working group is very active with members from the Schools of Medicine, Nursing and Public Health in Johns Hopkins as well as collaborators from other institutions. Currently researchers in the Center are working on datasets linking the REasons for Geographic and Racial Differences in Stroke (REGARDS) study and National Health and Aging Trends Study (NHATS) to Medicare claimsOrla Sheehan, MD, PhD

Every 4th Wednesday

3:00 p.m - 4:00 p.m. EST


Physical Function and Falls

DescriptionContactMeeting Occurrence
Falls can result in serious medical complications including hip fractures and head injuries. In many cases, those who experience a fall have a hard time recovering and their overall health deteriorates. Statistics show that more than 40% of people hospitalized from a hip fracture do not return home and are not capable of living independently again. The good news is that, with adequate knowledge, falls can be preventedYuri Agrawal, MD
