Abstract: Background: Prader–Willi syndrome (PWS) is a genetic disorder characterised by hyperphagia, intellectual disability and increased propensity to a range of medical disorders. To better characterise the clinical presentation of PWS across the lifespan, this study reports on the demographics and clinical diagnosis of individuals with PWS hospitalised in the United States. Methods: The National Inpatient Sample, an all‐payor administrative claims database of hospitalisations in the United States, was queried for patients with a coded diagnosis of PWS from October 2019 through December 2021. Hospitalisations for patients with PWS were matched to five non‐PWS hospitalisations based on age, sex, year and hospital characteristics. Results: There were 4400 (95% CI: 3,885 to 4,915) PWS hospitalisations, with a median age of 24. Compared to controls, PWS hospitalisations had longer hospital stays (median 5 vs. 3 days) and higher in‐hospital mortality (2.2% vs. 1.3%). Infectious (19.0%) and respiratory (16.2%) diagnoses were most common for PWS patients. Codes for overweight or obesity were present in 38.1% of PWS hospitalisations, with Hispanic ethnicity was associated with a higher odds of overweight/obesity in PWS patients (aOR 1.73; 95% CI: 1.11–2.71). Conclusions: PWS hospitalisations are characterised by higher healthcare utilisation and complexity compared to matched controls. The high prevalence of obesity and significant rates of infectious and respiratory conditions highlight specific health challenges for PWS patients. Validation of the Q87.11 administrative claims code is an essential step for ongoing health services research in this condition. [ABSTRACT FROM AUTHOR]
