ABSTRACT
Background: The U.S. Federal Government enacted the Screen for Abdominal Aortic Aneurysms Very Efficiently Act in January 2007. Simultaneously, the Department of Veterans Affairs (VA) implemented a more inclusive AAA screening policy for veteran beneficiaries shortly afterwards.
Our study aimed to evaluate the impact of the VA program on AAA detection rate and all-cause mortality compared to a cohort of patients whose aneurysms were identified by other abdominal imaging.
Methods: We identified veterans with an AAA screening study using the two existing Current Procedural Terminology (CPT) codes (G0389 and 76706). In the comparison group, eligible abdominal imaging studies included ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI) queried according to CPT codes between 2001 and 2018.
We used a difference-in-differences regression model to evaluate the change in aneurysm detection rate and all-cause mortality five years before and eleven years after the VA implemented the screening policy in 2007.
We calculated survival estimates after AAA screening or non-screening imaging of patients with or without AAA diagnosis and used multivariate Cox regression model to evaluate mortality in patients with a positive AAA diagnosis adjusting for patient characteristics and comorbidities.
Results: We identified 3.9 million veterans with abdominal imaging, a total of 303,664 of whom were coded has having an AAA US screening between 2007 and 2018. An AAA diagnosis was made in 4.84% of the screening group vs. 1.3% in the non-screening imaging group P<0.001, yet more aneurysms were found with general imaging studies (50,730 vs.15,449) (Fig 1).
On Kaplan-Meier survival analysis, patients with an AAA diagnosis had higher overall mortality than patients who screened normal; patients with aneurysms found with non-screening imaging had the highest mortality, log-rank P<0.001 (Fig 2).
The difference in differences regression analysis, showed that the absolute AAA detection rate was 1.55% higher (95% CI 1.2- 1.8), and the mortality was 13.89 % lower (95% CI 10.18 %-16.66 %) after the introduction of the screening program in 2007.
Multivariate Cox regression analysis in patients with AAA diagnosis (65-74-year-old) demonstrated a significantly lower 5-year mortality [HR 0.45 (95% CI 0.43-0.48)] for patients in the US Screening group P<0.001.
Conclusions: In a nationwide analysis of VA patients, implementation of AAA screening was associated with improved survival and a higher rate of AAA diagnosis. These findings provide further support for this program’s continuation versus defaulting to incidental recognition following other abdominal imaging.

Targeted violence continues against Black Americans, Asian Americans, and all people of color. The department of radiology diversity committee is running a racial equity challenge to raise awareness of systemic racism, implicit bias and related issues. Participants will be provided a list of resources on these topics such as articles, podcasts, videos, etc., from which they can choose, with the “challenge” of engaging with one to three media sources prior to our session (some videos are as short as a few minutes). Participants will meet in small-group breakout sessions to discuss what they’ve learned and share ideas.
Please reach out to Marta Flory, flory@stanford.edu with questions. For details about the session, including recommended resources and the Zoom link, please reach out to Meke Faaoso at mfaaoso@stanford.edu.

ABSTRACT
The emergence of Multi-Cancer Early Detection Screening Tests (MCED) – “liquid biopsy screening tests” – has generated enormous interest because they could fundamentally shift how cancer screening is done. One company is already offering an MCED test for clinical use as a “lab developed test” (LDT) – and thus addressing the question of “who will pay” has become urgent. These tests offer potentially transformative screening and clinical benefits, but their characteristics present unique challenges to payer coverage decision-making and generate concerns about the potentially high cost of widespread adoption.
We will present our ongoing work on examining the unique challenges that MCED present for payer coverage decision-making, drawing on our extensive experience with coverage and reimbursement for new technologies. We will focus on identifying the evidence generation strategies that could be pursued now to inform payer decision-making so that coverage policies can be developed that are appropriate and equitable for this ground-breaking technology.

ABSTRACT
As society progresses towards increasing pervasive computing levels, I design and build technology-enabled solutions to repurpose everyday devices to help people build resilience and grow wellbeing. I leverage biological and behavioral knowledge to design systems that balance user needs and health outcomes while mitigating surveillance and agency risks. In this talk, I present my research on efficacious and engaging sensors and interventions necessary in the population and public health domains. I share a series of research projects exploring and validating novel ideas on passive sensors – less dependent on subjective surveys or wearables – and subtle interventions that minimize workflow disruption. I show the promise of repurposing existing signals from computing peripherals (i.e., mouse and trackpad) or cars (steering wheel) into “sensorless” sensors and repurposing existing media as just-in-time micro-interventions that can work across multiple scenarios and populations. I discuss how these data could be used in collaboration with domain experts to study topics as varied as the interaction between stress and productivity in office workers, burnout prevention among clinical practitioners, or the prevention of depression among rural health workers. Finally, grounded in theories from neuroscience and behavioral economics, I propose the evolution of everyday “mundane” devices, such as chairs, desks, cars, or even urban lights, into adaptive and autonomous wellbeing-optimizing interventions. I close with a discussion of the research needed to systematically study ethics in pervasive technology for resilience, and wellbeing.
