Seminar Series

The CHPR Seminar Series typically focuses on research-in-progress (at any stage), recently completed research, innovative research methods, policy implications of health services research, pre-proposal discussion of research ideas or plans, or "practice presentations" for abstracts accepted for regional or national meetings.  Faculty, graduate students, and non-faculty researchers with a focus on health policy or health services are encouraged to present.  In addition, this is a great opportunity for presenting dissertations, thesis proposals, or thesis findings. 

The weekly seminars are held Wednesdays, 12-1 pm during the academic year, with a hiatus during the months of July and August. The seminars are usually located at the UCD Medical Education Building, Room 3207 (see schedule to confirm location). Seminars are open to all CHPR members, staff, students, and researchers external to UCD. Continuing Medical Education credit is available to practicing physicians for most sessions. Students taking EPI 291 may earn 1 unit of course credit for each quarter of regular seminar attendance. 

We welcome presentations from health policy and research professionals both internal and external to the University.  To be placed on the schedule, please contact:

"Hepatitis C Virus Treatment Prioritization Improves Population Health Outcomes"
Lauren E. Cipriano, Ph.D.
Assistant Professor, Management Science
Ivey Business School
June 21, 2017

Background: Payers face substantial affordability challenges when considering cost-effective but expensive treatments for common conditions. Given limited budgets, not all patients can receive treatment immediately. We formulate a framework to evaluate treatment prioritization policies, applying it to the example of hepatitis C treatment.

Methods: We develop a multi-period treatment budget allocation model to evaluate the trade-offs of treatment prioritization guidelines including first-come first-served, priority to patients with most severe disease, priority to patients with most severe disease with age-stratification, priority to patients in order of the incremental cost effectiveness ratio (ICER) of treatment, and a priority sequence identified through optimization to maximize population lifetime discounted net monetary benefit (NMB). For the case of hepatitis C, we compare prioritization guidelines in terms of the number of individuals treated, the number of individuals with compensated cirrhosis, the number of individuals who progress to end-stage liver-disease (ESLD), population total quality-adjusted life-years (QALYs), and NMB.

Results: First-come first-served treats more people at lower near-term risk of disease progression or complications. When age-stratification is included, priority to younger patients (compared to older patients with the same disease severity) results in fewer cases of disease progression and/or disease-related complications because of higher competing mortality risks faced by older patients.  A guideline developed from maximizing the population lifetime discounted NMB in a multi-period framework explicitly accounts for the trade-offs in the timing of prioritizing subgroups including the consequence of requiring other specific subgroups to wait longer for treatment and the expected QALYs lost from potential disease progression. In contrast, prioritization based on ICER does not incorporate the relative consequences of waiting across subgroups. In the case of hepatitis C treatment prioritization, the optimization strategy yields the greatest population QALYs and NMB, though prioritization by disease severity prevents more cases of ESLD.

Conclusions: Explicit prioritization can improve population health outcomes. Differences in outcomes between prioritization guidelines increase when the available budget is smaller. Prioritizing on ICER does not necessarily maximize QALYs over multiple cohorts because its allocation of treatment resources to one group does not account for the optimal timing of resources for other groups. Determining the optimal prioritization guideline is important in terms of care delivery and for evaluating alternative prioritization guidelines.

"Is your research worth doing? An introduction to value of information (VoI) analysis in healthcare"

Ed Wilson, Ph.D.  
Senior Research Associate in Health Economic
Cambridge Centre for Health Services Research (CCHSR)
at the University of Cambridge
Cambridge, England

FRIDAY August 11, 2017
This talk introduces the concept of “value of information” and then provides examples from the presenter’s experience to illustrate the main points.  Value of information analysis (VoI) estimates the expected benefit of a research project (e.g. a clinical trial) in terms of the value of the information it yields, and compares this with the cost.  VoI essentially estimates the return on investment in proposed research projects.

These principles can be used in a number of ways. Funders of research may find it useful to rank projects in terms of the expected return on investment from a variety of competing projects. Alternatively, trialists can use the principles to identify the efficient sample size of a proposed study as an alternative to traditional power calculations, and finally, a VoI analysis can be conducted alongside an economic evaluation as a quantitative adjunct to the 'future research' or 'next steps' section of a study write up.
The talk will conclude with thoughts about new applications of VoI and future research needs.

We encourage presentations from health policy professionals both internal and external to the University.  To be placed on the schedule, email Seminar Director, Jeffrey Hoch @ , or Kirstin Truitt @
