Abstract Body (Do not enter title and authors here): Introduction
Hypertrophic Cardiomyopathy (HCM) is an uncommon heart condition associated with serious complications. Advances in medicine have improved its prognosis. Despite this, such potentially life-saving improvements concerning the implementation of best practices are not ubiquitous; guidelines recommend management at specialized centers. Unfortunately, not all hospitals have specialized HCM centers. However, given that a sizeable portion of these specialists are also in academic centers (ACs), we hypothesize that ACs may be better positioned than non-academic centers to provide the highest quality care for HCM patients.

Purpose
Our study aimed to assess in-hospital outcomes and healthcare burdens among patient admissions with HCM diagnoses, comparing those treated at academic centers with those receiving care at non-academic centers. We examine all-cause in-hospital mortality, length of stay (LOS), hospital costs, and investigate ethnic differences in patients with HCM.

Methods
The National Inpatient Sample database was utilized to obtain HCM patient hospitalizations from 2012 through 2020 in the United States. Patient hospitalizations for which adult patients had a primary diagnosis of HCM were identified. Outcomes included all-cause in-hospital death, LOS, and hospital costs. All-cause in-hospital mortality was evaluated using multivariable logistic regression analysis. Multivariable lognormal regression models were used to estimate LOS and inflation adjusted cost outcomes.

Results
All-cause mortality unadjusted rates were 2.2% in non-teaching hospitals compared with 1.7% at teaching hospitals; however, this difference was not statistically significant (p =.235). Both unadjusted and adjusted hospital LOS were 32% shorter for non-teaching hospitals (p <.001). Both unadjusted and adjusted hospital costs were 46% lower for non-teaching hospitals compared to teaching hospitals (p <.001; $37,829 vs $70,216). For both LOS and cost, the overall interaction between race and teaching status was statistically significant (p < .001.)

Conclusion
Our study shows variations in hospital outcomes and costs between teaching and non-teaching hospitals. Non-teaching hospitals displayed shorter stays and lower costs. Additionally, the interaction of race and teaching status significantly impacted length of stay and costs. These results underscore the necessity of tailored interventions to address healthcare delivery and resource inequities, especially in teaching hospitals.
