Seminar assesses efforts to improve delivery of cardiovascular care

09 Apr 2015

Improved Delivery of Cardiovascular Care (IDOCC) was an innovative, multifaceted quality improvement program conducted between 2008 and 2011, designed to assist primary care providers in improving their delivery of evidence-based care for the secondary prevention of cardiovascular disease.

Catherine Deri Armstrong, associate p
rofessor of economics at the University of Ottawa, leads a CHEPA seminar on Weds. April 15 that examines the effectiveness of the IDOCC, an intervention that involved sending external Outreach Facilitators into participating family medicine practices to identify areas for improvement, set care improvement goals, and provide tools, approaches and support to help the practices achieve their goals.

In total, 191 family physicians from 83 primary care practices from a large health region in Eastern Ontario underwent the intervention.

Set up and rolled out as a stepped wedge trial - with groups of practices (clusters) crossing over from the control arm to the intervention arm at different points in time - the IDOCC study design allows for the estimation of causal relationships between the intervention and outcomes of interest.

Deri Armstrong’s presentation summarizes the results from two separate studies examining the effectiveness of IDOCC: 1) an analysis based on chart audit data examining changes in patient-level composite scores capturing physicians' adherence to evidence-based care, and 2) an analysis based on administrative data examining changes in hospitalizations and primary care visits.

Deri Armstrong is an Associate Professor in the Department of Economics at the University of Ottawa as well as the academic director of Statistics Canada's Carleton Ottawa Outaouais Local Research Data Center (COOL RDC) and the president of the Canadian Women Economists Network.

Her research areas include economic evaluation, applied health and labour economics.

The seminar will be held on Weds. April 15 in CRLB-119 from 12:30 to 1:30 p.m. The seminar will be available remotely for those unable to attend.
