ODP381 Changes in Perceptions of Pediatric Endocrinologists (PE) and Urologists (PU) to Infants and Children regarding care of individuals with 46,XY DSD

INTRODUCTION: Over recent decades, controversy regarding standards of care has contributed to questioning past management recommendations for infants and children with a 46,XY DSD. Surveys conducted in 3 waves (2003, 2010, 2020) provide evidence of changes in recommendations for care have changed over this period. METHODS: Online surveys of the members of the Pediatric Endocrine Society (PE) and Societies for Pediatric Urology (PU) included case vignettes representing partial androgen insensitivity syndrome (PAIS), micropenis resulting from primary testicular failure, and penile ablation (non-DSD). Survey items included questions regarding recommended gender of rearing (GoR), genital surgery (and timing), and disclosure of diagnostic details to patient. RESULTS: The newborn PAIS vignette included elevated LH and FSH and a 1.2 cm. phallus that increased to 1.7 after exogenous testosterone. Male GoR was chosen by 47, 55 & 55% PE and 81, 83 & 69% of PU in waves 1 to 3, respectively; 27 PE and 28% PU chose an added "non-binary" option in 2020. The recommendation that parents, rather than patients, should decide about perineal hypospadias repair was chosen by 70, 60 & 50% of PE and 93, 90 & 79% of PU. Recommending against surgery were 25, 22 & 10% PE and 23, 13 & 8% PU. Recommending surgery be completed at <1 year of age: 56, 59, 66% PE and 69, 78, 84% PU. Recommendation against disclosure of the underlying condition to the patient 12, 17 & 28% PE and 17, 19 & 22% PU, while 35, 28 to 32% PE and 34, 43 & 30% PU recommended that disclosure occur by 11 years of age. For the penile ablation vignette, 78, 92 & 92% PE and 98, 95 & 97% PU recommended male GoR. The 2020 non-binary option was chosen by 4 and 2% PE and PU. The majority of both groups recommended male GoR for the micropenis vignette with testicular failure; 94, 94 & 89% PE and 96, 97 & 88% PU. The decline in 2020 resulted from the recommendation of the non-binary option by 9% PE and 8% PU. CONCLUSIONS: It seems clear that a female GoR recommendation is currently rare across 46,XY vignettes with evidence of testicular function during at least some of fetal life. It is also apparent that the current emphasis/controversy regarding GoR has resulted in confusion as to how to apply this poorly understood concept. The resulting shift of delaying decisions regarding surgery until the patient can decide is inconsistent with the recommendation that hypospadias repair occur before age 1 year. Finally, lack of or delayed disclosure is inconsistent with patient centered care recommendations. Presentation: No date and time listed
