What’s the Actual Value of Common Tests and Procedures?: Dr. Rita Redberg, Cardiologist and Professor of Medicine at UCSF
10/09/2026 | 29 mins."It's really hard to justify a test that has any complications if there isn't any reasonable expectation of benefit," says Dr. Rita Redberg, who has spent her career trying to help fellow clinicians consider the actual value of routine screenings and diagnostic testing in asymptomatic patients. Dr. Redberg -- a cardiologist and professor of medicine at the University of California, San Francisco for more than three decades -- is one of the leading voices advocating for a “high-value care” approach, an uphill fight in a healthcare system that tends to reward action over restraint. Her highest profile effort was launching the instructive “Less is More” series in JAMA Internal Medicine when she served as its editor-in-chief for 14 years.
On a related track, her research on the assessment of the safety and effectiveness of medical technology, specifically high-risk cardiovascular devices, has yielded a troubling picture. "We found only 1% of devices enter the market through the FDA's most rigorous approval process. The high-quality evidence to support benefit for these devices that I had assumed was present, wasn't actually there.”
Join Raise the Line host Lindsey Smith for an eye-opening exploration of what Dr. Redberg considers to be the overlooked risks and false reassurance of common tests and procedures, and her efforts to put the “do no harm” principle of medicine at the forefront of everyday practice.

03/09/2026 | 36 mins.For millions of young women and girls, often the first place they turn with questions about their bodies isn't a doctor's office, it's social media which can lead to encountering many misconceptions and outright misinformation. Or, if the right voices show up, it can mean something else entirely.
Our guest today, Dr. Charis Chambers, is one of those voices. She’s a board-certified OB/GYN with specialty certification in Pediatric & Adolescent Gynecology, and Chief Medical Officer at Clue, a leading period and cycle-tracking app. She's also the founder of The Period Doctor, a platform she launched in 2019 to provide medically accurate reproductive health information and to place more minority physicians in the spaces where patients are already looking for answers.
As she tells Raise the Line from Elsevier host Lindsey Smith, Dr. Chambers embraces the role of being a bridge between generations: "I can serve as a medical mediator where I advocate for the child and then educate the parent so that the child’s concerns are met."

Her new book, The Period and Puberty Parenting Revolution, which tackles many of the same myths she encounters every day in her clinic;
Why stubborn myths around periods rarely hold up once you ask where they come from;

27/08/2026 | 30 mins."I'd already finished my cardiovascular unit. I'd finished my pulmonary unit. I had never heard about this in any of my classes." That was Dr. Joel Bervell's reaction to discovering that a device used every day in hospitals -- the pulse oximeter -- reads less accurately on darker skin tones. He posted a 30-second video about this consequential discrepancy that, to his utter surprise, gained over 500,000 views by the next morning.
That video launched Dr. Bervell into orbit as a social media presence and created his identity as The Medical Mythbuster. In just a few years, he’s built a following of two million people, earned a Peabody Award and was named to the inaugural Time 100 Creators list, all while finishing his residency.
On this episode of Raise the Line, host Lindsey Smith welcomes Dr. Bervell to explore the roots of this kind of bias and the real world impact of drawing attention to it. “The most impactful biases in medicine exist because no one stops to ask who was included in the original data and who was left out,” Dr. Bervell explains.
Stay tuned to also learn about:
His YouTube animated series The Doctor is In which helps kids understand how their bodies work, as well as providing medical role models;
How to build trust with marginalized communities;
His forthcoming book, The Default Body which examines who medicine was actually designed for.

20/08/2026 | 32 mins.Despite gains in recent years, Black, Hispanic, and Asian communities are still under-represented in the U.S. nursing workforce. We’re going to explore that gap and how to close it on this episode of Raise the Line from Elsevier with Dr. Ernest Grant, Vice Dean for Diversity, Equity, Inclusion and Belonging at the Duke University School of Nursing. "You get a patient who is more compliant when they see someone who looks like them, who is from their culture and who can advocate on their behalf," he tells host Lindsey Smith.
Dr. Grant bases that and other insights on a rich professional background that includes 50 years in nursing, being a leading advocate for his profession and breaking down barriers himself as a male nurse of color and the first man elected president of the American Nurses Association.
In this thoughtful conversation, Dr. Grant reflects on what it took to earn credibility in leadership roles, how he’s navigating the political climate on DEI initiatives, and the causes and solutions to the persistent shortage in nursing faculty, among other pressing issues. Tune in for a uniquely-informed look at what it will take to build a stronger, more representative nursing profession.

13/08/2026 | 21 mins.What does it take to compete on the world's biggest stage and then pivot to one of the most demanding training paths in professional life? Today's guest, Samantha "Sammy" Kolowrat, has done both, and she has some fascinating insights into the commonalities of those two worlds on this episode of Raise the Line. “Something that really drew me to medicine is the team atmosphere that’s there as you work towards a common goal, and there's this level of intensity that’s very reminiscent of the experiences I had as a professional athlete.”
Originally from Prague, Kolowrat represented Czechia at six IIHF Women's World Championships and the 2022 Beijing Olympics, and also captained the Division I women's hockey team at the University of Vermont while earning degrees in biology and pharmacology.
As she starts an anesthesiology residency at Vanderbilt University, she credits her athletic career with shaping how she handles pressure, feedback, and teamwork in medicine. "The more I improve, the more knowledge I acquire, the more skills I hone, the better care my patients get," she tells host Lindsey Smith, describing what drew her to a field that rewards the same relentless fine-tuning as elite sports.
This engaging conversation also explores:
How crippling performance anxiety as a Division I athlete ended up preparing Kolowrat for the operating room;
Why she was drawn to anesthesiology's "well-oiled machine" atmosphere;
The mentorship gap she's working to close for the next generation of athlete-physicians.
