EP-119 Scientific Approach Needed - Gender-Affirming Care Highlighting the UK’s NHS Cass Review on gender-affirming care with a focus on the often cited “suicide ideation” propaganda in Washington State politics. Beginning in 2020 the National Health Service (NHS) in England commissioned a comprehensive multi-year review of gender-affirming care for children and adolescents. The scientific review, published in 2024, was a complete rebuke of the prevailing approach to gender-affirming care in the UK. As a result of the review, the UK medical establishment and policy makers changed their approach to treatment for gender dysphoria in youth. Despite the updated science, activists and policymakers in Washington State continue to use emotional propaganda and pseudoscience to guide their campaigns and legislation. The science has been reviewed. We must change our ways. “She blinded me with science!” - Thomas Dolby ‧ 1982 Information war “Save the children” has been a manipulative political ploy for decades. Both major political parties have used it as a vehicle for inserting ideology into policy. It may seem trite from an experienced lens of political analysis, but the effectiveness proves its longevity as a tactic. There is a pernicious use of junk science fueling political propaganda regarding “youth gender care” in our society. The “save the children” slogan has been tied into a gordian knot of misinformation. The claims of science are used to tighten this twisted knot weaving through our community. It’s often hard to know who to trust when information outlets contradict each other with claims of factual science: “Not that science, this science. Not this science, that science.” How do parents and community members inform themselves when the information space is littered with manipulation and a constant barrage of conflicting data sets? How are they to participate when each extreme faction emotionally invokes the language of “save the children” at every turn? In the end, the very object of manipulation must be the guiding light forging a path forward to truth and reason - science. Pseudoscience, popularized through political propaganda, states that youth gender-affirming care is necessary to combat teen suicide rates. This basic emotional plea invokes the time-honored manipulation of the “save the children” mantra. But the NHS Review debunked the pseudoscience; and it presented a peer-reviewed scientific assessment of youth gender-affirming care and the holistic issue of gender dysphoria. National Health Service Commissioned Cass Review The Cass Review was an independent review of the UK's NHS gender identity services for children and young people. The scientific endeavor culminated with a lengthy 388-page review led by Dr Hilary Cass. The mission for the Cass Review as stated in the document: “The Review was commissioned by NHS England to make recommendations on how to improve NHS gender identity services, and ensure that children and young people who are questioning their gender identity or experiencing gender dysphoria receive a high standard of care, that meets their needs, is safe, holistic and effective.” Trust the Science!  Advocates for gender-affirming care often cite research to support their stance that such interventions, including puberty blockers and hormone treatments, are crucial in reducing suicide risk among transgender youth. The often-quoted study is titled “Pubertal Suppression for Transgender Youth and Risk of Suicidal Ideation.” This study suggested that transgender and gender non-conforming youth who received puberty blockers exhibited lower rates of suicidal ideation compared to those who did not.  However, the Cass Review highlights a significant methodological flaw in the study: The study did not adequately account for the underlying mental health conditions of the participants. This oversight could lead to a false correlation betwe
