Behind The Knife: The Surgery Podcast

Why do millions of patients qualify for bariatric surgery, yet only a fraction ever make it to the operating room?
Hosts
·      Matthew Martin, trauma and bariatric surgeon at the University of Southern California/Los Angeles General Medical Center (Los Angeles, California)
·      Adrian Dan, bariatric and MIS surgeon, program director for the advanced MIS bariatric and foregut fellowship at Summa Health System (Akron, Ohio)

·      Katherine Cironi, general surgery resident at the University of Southern California/Los Angeles General Medical Center (Los Angeles, California)
Learning objectives:
This episode explores disparities in access to bariatric surgery through three key studies examining eligibility, referral patterns, and weight stigma.
References:

Article #1: Socioeconomic disparities in eligibility and access to bariatric surgery: a national population-based analysis (2010, Martin et al.) https://pubmed.ncbi.nlm.nih.gov/19782647/
Analyzed national U.S. datasets to compare patients eligible for bariatric surgery with those who underwent surgery. 

Although more than 22 million Americans met criteria for bariatric surgery, only about 0.4% underwent surgery in 2006.

Patients eligible for surgery were more likely to be female, uninsured, lower income, and from racial and ethnic minority groups, while those receiving surgery were disproportionately Caucasian women with private insurance.

 This discussion highlights insurance coverage as one of the largest structural barriers to care.

Article #2: Investigating racial disparities in bariatric surgery referrals (2019, Johnson-Mann et al.) https://pubmed.ncbi.nlm.nih.gov/30824334/
This study focused on referral patterns within a primary care network. 

Among nearly 4,700 eligible patients, only 5% were referred to bariatric surgery. 

Referral disparities were seen across sex, ethnicity, and insurance status.

Hispanic patients were significantly less likely to be referred and were far more likely to be uninsured or self-pay. 

The study emphasizes that disparities begin long before the operating room, often at the level of primary care referral and institutional access policies.

Article #3: Assessing Weight Stigma Interventions: A Systematic Review of Randomized Controlled Trials (2025, Wang et al.) https://pubmed.ncbi.nlm.nih.gov/40227369/
Examined interventions designed to reduce weight stigma.

Across 56 randomized controlled trials, most interventions demonstrated improvements in attitudes toward obesity. 

Effective approaches included emphasizing the biologic and environmental causes of obesity, promoting weight-inclusive healthcare, fostering empathy through shared narratives, and using cognitive dissonance strategies to challenge implicit bias. 

However, changing attitudes does not necessarily translate into improved clinical behavior or patient outcomes.

Together, these studies demonstrate that disparities in bariatric surgery occur at multiple stages: eligibility, referral, access, and treatment. Structural barriers, provider bias, insurance limitations, and societal stigma all contribute to inequitable care. Herein, we emphasize the importance of expanding access pathways, improving provider education, and actively reducing weight stigma to ensure equitable surgical care for all eligible patients.

Prehospital blood is one of the hottest debates in trauma resuscitation — and the evidence just got a lot more interesting. In this episode, Drs. Patrick Georgoff and Ayman Ali sit down with Dr. Ed Barnard, UK defense professor of emergency medicine and author of the landmark SWIFT trial, and Dr. Juan De Chesney, trauma surgeon and pioneer in prehospital blood programs, to break down what we actually know about getting blood to patients before they hit the doors. The SWIFT trial — the largest prehospital whole blood RCT to date — found no superiority of whole blood over component therapy, but the story is far more nuanced than a negative headline suggests. From the logistics of carrying blood on a helicopter to the stark reality that only 1.8% of US ground EMS carries any blood products at all, this conversation exposes both the progress and the enormous gaps that remain.

Get a behind-the-scenes look at one of the most anticipated sessions from the Association of Surgeons of Great Britain and Ireland Annual Conference: “Bad Day on Call.”
In this session, expert surgeons from the United States, United Kingdom, and Canada work through challenging real-world acute care and trauma cases. As each case unfolds, the panel explores key decision points while highlighting both the similarities and differences in surgical management across healthcare systems.
This year’s panel featured an outstanding group of acute care and trauma surgeons, including Dr. Rob Lim, Dr. Courtney Collins, Dr. Michael Cripps, Dr. Caroline Reinke, Dr. Chris Schlachta, Mr. Christian Macutkiewicz, Mr. Adam Peckham-Cooper, Miss Kate Hancorn, and Mr. Dimitrios Damaskos.
