COVID-19 Tracking and Prevention


Prior Mongan Faculty Leader to Guide COVID-19 Efforts as New CDC Director

Rochelle Walensky, MD, MS

One of Mongan Institute’s prior faculty leaders, Rochelle Walensky, MD, MS, is the new Director of the Centers for Disease Control and Prevention (CDC) charged with helping to oversee the nation’s response to the COVID-19 pandemic. As a scientist and prior Co-Director of the Medical Practice Evaluation Center (MPEC) within the Mongan Institute, Dr. Walensky conducted groundbreaking research on the economic evaluation of HIV prevention, diagnosis, and treatment policies as a senior member of the Cost-Effectiveness of Preventing AIDS Complications (CEPAC) team. Her 2006 analysis in the Journal of Infectious Diseases was the first to determine the survival benefit of HIV treatment in the United States. In 2017 she led a study demonstrating the clinical impact and cost of achieving 90% HIV viral suppression in the U.S., and in 2019 she testified before the U.S. House Committee on Oversight and Reform on the value of medications for HIV pre-exposure prophylaxis (PrEP), medications that are both highly effective and very costly. Among her many prior research leadership roles include chairing the NIH Office of AIDS Research Advisory Council, acting as an advisor to the World Health Organization and UNAIDS, and serving as an expert on Governor Baker’s COVID-19 Advisory Board. In her new role as Director of the CDC, Dr. Walensky oversees a staff of over 10,000 and a budget of $12 billion, supporting programs in immunization, infectious diseases, environmental health, disease prevention, injury prevention, and public health preparedness and response.

Engaging patients in decisions about rescheduling colonoscopies delayed due to COVID-19

Karen Sepucha, PhD

Leigh Simmons, MD

Principal Investigators: Karen Sepucha and Leigh Simmons  

Co-Investigators (from MGH): Steve Atlas, Sanja Percac-Lima, James Richter

As the initial surge of patients with COVID-19 recedes, one pressing issue facing health care systems is how to manage the large and growing backlog of screening tests and elective procedures. To further complicate matters, public health officials warn that further waves of infection may occur over the next 12-18 months, and each may cause additional restrictions on capacity, increasing backlogs and delaying needed care even more. Managing demand with reduced capacity while planning for additional shutdowns represents a key new challenge for health care delivery systems during this crisis. Moreover, even if there is capacity, many patients may feel differently about the value of seeking healthcare, including cancer screening, until an effective treatment or vaccine for COVID-19 is found. 


In this PCORI-funded study, investigators will examine the distribution of patients’ preferences for rescheduling a screening or surveillance colonoscopy that was delayed or postponed due to COVID, and factors associated with those preferences. Then, we will study whether shared decision making tools and training will increase patients involvement in decisions, increase their intention to follow through with some type of colon cancer screening, and reduce decisional conflict. There are many challenges to resuming healthcare during this crisis, and this study will address important research questions about how to do this in a safe, equitable and patient-centered manner.

Dr. Sepucha is Director of the Health Decision Sciences Center and an associate professor in Medicine at Harvard Medical School. Dr. Simmons is Medical Director of the Health Decision Sciences Center and an internal medicine physician at Massachusetts General Hospital.
