COAH Working Groups


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 claims analyses and other sensitive health data has expanded the Center's analytic capabilities and infrastructure.Jin Huang, MS

Every 4th Monday

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


Cognitive and Sensory Functions

DescriptionContactMeeting Occurrence
We are seeking to better understand the relationship between sensory loss - primarily vision and hearing loss - and cognitive function in older adults. This includes research aimed at identifying mechanisms underlying sensory-cognitive relationships, as well as methodological approaches to measuring cognitive function in older adults with sensory impairments.Alden Gross, PhD

Every 3rd Monday

11:00 a.m - 12:00 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 Translation 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

8:30 a.m - 9:30 a.m. EST


Frailty and Multisystem Dysregulation

DescriptionContactMeeting Occurrence
An integral part of the research mission of COAH and the JHU Older Americans Independence Center (OAIC) is to identify the causes of and treatments for frailty, a syndrome characterized by reduced strength, energy, and activity. The Frailty and Multisystem Dysregulation Working Group meets twice monthly to engage in scientific discussion, project planning, manuscript development, and funding strategies related to frailty science. Headed by the leadership of the OAIC, a core group of researchers from multiple disciplines (including geriatrics, cardiology, biostatistics, epidemiology, endocrinology, infectious diseases, and mental health) at Johns Hopkins and beyond convenes regularly to envision, develop, and advance research on important questions on the etiology, measurement, and amelioration of frailty, its consequences and the translation of effective strategies into clinical practice. This working group serves as a significant engine for propelling frailty related projects, including a number of recently funded NIH grants. In addition, it provides organization to support the development of international leadership in the field of frailty via participation and leadership of important symposia at the annual International Conference on Frailty and Sarcopenia Research, and at the 2017 IAGG World Congress on Gerontology and Geriatrics.Brian Buta, MHS

Every 2nd & 4th Wednesday

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


Administrative Claims Analyses

DescriptionContactMeeting Occurrence

The study of healthcare utilization is critical to identifying inefficiencies in resource allocation and potential cost savings as healthcare costs continue to rise. 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.  The Center has recently established and Linked Administrative Data Resource (LADR) that includes a secure “cold room” designed to house highly restricted sensitive data such as Medicare claims that can address these important research questions concerning healthcare utilization. Linking administrative claims data with epidemiological studies of aging and clinical trials allows researchers to address research questions on healthcare utilization in innovative ways The Administrative Claims Analyses working group is very active with members from the Schools of Medicine, Nursing, and Public Health at Johns Hopkins as well as collaborators from other institutions. Currently researchers working on Medicare datasets linked to the National Health and Aging Trends Study (NHATS) and the REasons for Geographic and Racial Differences in Stroke (REGARDS) project.

Physical Function and Falls

DescriptionContactMeeting Occurrence
This working group convenes all Hopkins investigators involved in research related to falls, and/or physical function/activity measurement (e.g. wearables, accelerometry).  We provide periodic updates of ongoing studies, discuss study methodologies and best practices, and review new research ideas.Yuri Agrawal, MD
