dc.descriptionThis study describes the prevalence and demographic characteristics of children diagnosed with a sex or gender difference and changes. The study aims to describe the clinical management for children diagnosed with a sex or gender difference and changes, with a focus on hormone prescribing patterns, surgical interventions, and ordering for screening studies. Finally, the study also examines the morbidity associated with a diagnosis of a sex or gender difference compared to population controls of similar age, race/ethnicity, insurance status and location. <br><br> #### Significance - Sex Chromosome Aneuploidies (SCAs) are common, and the rate of early diagnosis is rapidly increasing as prenatal screening becomes standard of care, but research is lagging. - SCAs affect mental and physical health. - Lack of guidelines to inform clinical care in pediatrics negatively affects patient outcomes. <br><br> #### Study Design This is an observational study using a national sample of pediatric patients at tertiary care children’s health systems (PEDSnet). Patients with a diagnosis of SCA in PEDSnet will be used to: 1. Quantify morbidity and healthcare utilization relative to a matched control group (nested case-control design). 2. Describe current clinical care practices. 3. Prepare for future comparative effectiveness studies. <br><br> #### Study Aims **Aim 1:** Quantify co-existing diagnoses and healthcare utilization associated with a diagnosis of SCA compared to the general pediatric population.<br> **Aim 2:** Describe and compare the current clinical care practices for youth with SCA across the US.<br> **Aim 3:** Develop a computable phenotype to identify a specific SCA population, TS girls on estradiol (E2), in preparation for a future comparative effectiveness study using PEDSnet data. <br><br> #### Cohort Definition Aim 1 analyses will include individuals in the PEDSnet database with an outpatient encounter (E&M code for outpatient service) who were 0-26 years of age between 2009 – 2019. <br> Aim 2 will build upon this cohort but will only include the four primary groups: TS, XXY, XXX, and XYY. TS and XXY groups will be stratified by site (XXX and XYY will likely have too few to evaluate by site, but overall care practices will still be described). <br> Aim 3 analyses will only include females in PEDSnet with TS >10 years of age as identified in Aims 1 and 2.
dc.description.abstractStudy aimed to describe clinical outcomes in youth with sex chromosome aneuploidies (SCAs) and the care these individuals receive. The study specifically aims to quantify co-existing diagnoses and healthcare utilization associated with a diagnosis of SCA compared to the general pediatric population; to describe and compare the current clinical care practices from youth with SCA; and to develop a computable phenotype to identify a specific model SCA population, TS girls on estradiol (E2) by route of administration, in preparation for a future comparative effectiveness study.
