Emergency department use by seniors: seminar looks at new models of care

11 Nov 2014

Older adults are frequent users of the emergency department and have worse outcomes than younger adults.

A CHEPA seminar being given by Dr. Andrew Costa on Nov. 19 will look at new models of care for seniors in the context of emergency department use and examine their implications.

Costa, an assistant professor and recipient of a newly-endowed chair in Clinical Epidemiology & Aging in McMaster’s  Department of Clinical Epidemiology & Biostatistics (CE&B)  notes  that  home care patients are a frail subgroup of community-dwelling older adults who account for a large proportion of the household population over age 65.

They are also heavy users of hospital emergency departments and Costa says many of their visits are potentially preventable.

He will explain the development of decision support tools that can help predict unplanned emergency department use and aid in geriatric emergency care, and also talk about new models of care and their translation into practice in Ontario and beyond.

As well, Costa will describe research that uses observational data and randomized methods to evaluate models of emergency department avoidance in real-world practice. He will also address the policy challenge of new models of care for emergency department avoidance and “senior friendly” care in emergency departments.

In addition to his positions with CE&B, Costa is the Research Lead at the DeGroote School of Medicine, Waterloo Regional Campus. He is an interRAI Fellow where he is engaged in the Network of Excellence in Acute Care (iNEAC) on its Steering Committee and leads the Emergency Department Working Group.

Formerly, he held a CIHR Post-doctoral Fellowship at the Institute for Clinical and Evaluative Sciences (ICES), Mount Sinai Hospital and the Institute of Health Policy, Management and Evaluation, University of Toronto.  

He has received CIHR awards (Rising Star, Age + Prize) for his research in health services and policy research.

Costa earned his PhD from the School of Public Health and Health Systems, University of Waterloo. 

Broadly, Costa’s research promotes evidence-based management and policy in elder care, including the development and evaluation of models of care focused on avoidable emergency department use and care of the elderly in emergency departments.  

Costa’s work makes use of large health care data repositories, multi-site prospective cohort studies, and pragmatic trial methods.

The seminar will be held Wednesday Nov. 19 in CRL B119, from 12:30 p.m. to 1:30 p.m. All are welcome to attend. The seminar will be available remotely for those who are unable to attend.
