Rutgers Global Health Institute core faculty members Gregory Peck and Shawna Hudson are conducting research on new health care models emphasizing primary care and prevention over emergency care as well as the role of community engagement in underserved communities, as Rutgers Today reports in the following article.


If more people have access to health insurance, we have to be sure the death rates of those with certain chronic conditions are decreasing.

This is one of the statements Gregory Peck, an acute care surgeon and associate professor at Robert Wood Johnson Medical School, will be researching on behalf of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) at the National Institutes of Health (NIH). He is the recipient of NIH grants totaling more than $1 million through a recent two-year award from the New Jersey Alliance for Clinical and Translational Science (NJ ACTS), which is a Rutgers hub of the National Center for Advancing Translational Sciences, and now a four-year award from the NIDDK.

Peck recently published two studies investigating death rates for gallstone disease, a disease of the abdomen that causes right-sided belly pain after eating, which shares risk factors with other deadly diseases. His study, published in Gastro Hep Advances, found that between 2009 and 2018, the number of deaths of people in New Jersey with diagnosed gallstone disease (1,580) remained steady and did not improve, and that deaths in Latinos ages 65 and older potentially increased.

His study in the Journal of Surgical Research found that, after Medicaid expansion in 2014 as compared to before, the amount of emergency surgery to remove the gallbladders for gallstone disease decreased in the state overall, but increased in people with Medicaid. While fatality from gallbladder removal surgery decreased for those 65 or older, there was increased death from surgery in the younger population and a trend of more death in the population with Medicaid. Further, the relatively decreased amount of gallbladder removal surgery occurring in ambulatory outpatient care centers did not necessarily help this.

Peck discusses the implications of the findings on a new shift in health care to prevention models.

Why did you focus on gallstone disease?

As a metabolic disease, gallstone disease is also linked to heart disease, cancer, diabetes, obesity, and a sedentary lifestyle. In fact, heart disease, which is the No. 1 killer in America, and gallstone disease, which is the No. 1 digestive disease requiring surgery in America, share the risk factors of high levels of bad cholesterol type and obesity.

How do these studies inform public policy?

The amount of people dying with gallstone disease – most of whom require surgery – over the past decade has not gotten better. That’s 160 people a year who still are dying from a preventable death such as gallstone disease. Making progress is what this type of epidemiologic study focuses on, and concerningly, we might not have made good progress.

If Medicaid expansion didn’t positively affect the death rate of people with gallstone disease and we see it increase, specifically in older Latino populations, we need to be asking if we are helping people of color and those who live in communities with lower socioeconomic status improve health or [if we are] treating them sooner to prevent emergency surgery and, especially, decreasing death from emergency surgery. Insurance expansion is certainly needed, but we have to ensure the action-specific pieces of policy impact the population requiring surgery in a patient-centered way.

The real goal is preventing the disease from even occurring. When we pass public health policy, we need to advocate for preventive care that reaches people through their community. Right now, the findings show that we might just be providing people with insurance cards who find themselves still needing to use the emergency department. Instead, that insurance should help them visit their primary care doctor, who can help them make changes like decreasing their bad cholesterol levels, which contribute to gallstone disease, and help them access care in ambulatory surgery centers sooner.

We need to cultivate preventive health care rather than ballooning the investment in emergency health care, which does not solve current inequities.

What other steps to improve access to care should be taken?

We propose a novel population health approach that shifts from the reactive treatments of emergency disease to proactive prevention. One place to start is increasing access to appropriate outpatient elective health care for underrepresented groups with barriers to preventive care, such as by increasing health insurance that incentivizes the behaviors toward improved health. A first step for my research group is to focus on diseases that currently require as much emergency as elective care, such as gallstone disease, and understand this by understanding who presents to the hospital, as to dial this back into the community level, to decrease hospital care.

In addition, in primary care, laboratory, radiology, or ambulatory care settings. we need to improve communication with people with low English proficiency – especially how well prevention is explained in a patient’s primary language. Language barriers might also prevent them from understanding the importance of cholesterol or blood pressure control over the one, two, and three decades of life, or how they find access to diagnostic tests or treatment needed earlier.

How is Rutgers working to increase primary care knowledge in underserved communities?

Shawna Hudson, the co-director of community engagement for NJ ACTS, and my research mentor, is researching how representatives rooted in the community can help health care providers and researchers better understand how we can use community engagement to involve people in communities’ preventive care as to decrease risk factors for chronic disease before they need hospital-based care and, more importantly, emergency surgery.

One initiative is the Community Engagement Virtual Salons, which help researchers and health care providers at NJ ACTS engage with patients and community members about how biomedical and clinical research leads to action through understanding disease and then enacting policy. In these sessions, the public serves as experts to provide feedback from a community perspective. This allows the medical profession to build relationships with community partners and increase the culturally sensitive participation of hard-to-reach populations.
