Research Overview
Dr. Politi is a clinical psychologist and an associate professor in the Division of Public Health Sciences, Department of Surgery, at Washington University in St. Louis. Dr. Politi’s research program focuses on using systematic methods to help patients and clinicians work through the uncertainties of health decisions through developing and evaluating decision tools, examining techniques to aid clinical discussions about health decisions, and exploring ways to improve communication about risks. Her research also investigates the influence of numeracy and health literacy on medical decision-making.

Dr. Politi teaches a course in the Master of Population Health Sciences program entitled Principles of Shared Decision Making and Health Literacy in the Clinical Setting. She also co-teaches a class with Dr. Anke Winter in the Master of Population Health Sciences program on Comparative Effectiveness Research.

Grants

Active Projects:

A Conference Grant to Implement Comparative Effectiveness Research Into Policy 
The goal of this grant is to host a series of conferences dedicated to promoting and building CER infrastructure, disseminating CER results, identifying opportunities for implementation and incorporation of CER findings into health policy, and CER career development. Visit the PCOR website.

Supporting Decisions about Health Insurance to Improve Care for the Uninsured
The goal of this project is to compare previously developed decision support strategies about health insurance options to usual care health insurance materials. We will evaluate these strategies’ impact on understanding and ability to compare health insurance plan information. We aim to improve currently uninsured individuals’ decision making about health insurance as they prepare to enroll in the Affordable Care Act health insurance exchanges.

Comparative Effectiveness of Encounter Decision Aids for Early-Stage Breast Cancer across Socioeconomic Strata
Dr. Politi received a subcontract award on a PCORI contract through Dartmouth College and will be working with the primary investigator, Marie-Anne Durand, PhD, and co-investigator, Julie Margenthaler, MD, to examine how to support women of lower socioeconomic status with early-stage breast cancer through their treatment decisions. The research team will provide point-of-care decision aids for these women to help increase their knowledge, decision confidence, and quality of life after a breast cancer diagnosis.

Supporting Decisions About Cancer Clinical Trials in Rural Cancer Centers
This is a pilot project partnering with Southern Illinois University School of Medicine (SIUSM) through the P20 2016 Collaborative Cancer Disparities Research Program addressing rural cancer disparities. Dr. Politi is the principal investigator with Swati Pathak, MD, an oncologist at SIUSM. Their project will expand on previous knowledge of shared decision-making tools developed to support decisions about clinical trial participation, bringing an evidence-based research tool to rural communities. The project will address the unique barriers of rural cancer residents and utilize their feedback to help support rural cancer patients participation in clinical trials.

Supporting Decisions about Health Insurance to Improve Care for the Uninsured
The goal of this project is to compare previously developed decision support strategies about health insurance options to usual care health insurance materials. We will evaluate these strategies’ impact on individuals’ understanding and ability to compare health insurance plan information. We aim to improve currently uninsured individuals’ decision making about health insurance as they prepare to enroll in the Affordable Care Act marketplace plans. 

Facilitating Shared Decision Making About Lung Cancer Screening

  • Shared decision making and patient decision aids can help people understand the evidence about lung cancer screening and decide whether yearly lung cancer screening is right for them. We have developed a tool to facilitate patients’ choices about yearly lung cancer screening.  
  • Learn more about lung cancer screening through this decision tool.
