Abstract
Background: Heart failure is a growing concern in the U.S., affecting nearly 6.5 million Americans aged 20 and older, with over 960,000 new cases diagnosed annually. It contributes to 8.5% of heart disease-related deaths. Previous research has explored the impact of teaching hospital (TH) status on outcomes across various diseases. This study aimed to determine whether TH status influenced outcomes for heart failure patients. Methods Data were drawn from the 2021 National Inpatient Sample, including 6,666,752 admissions. After filtering for heart failure (ICD10 I50), 16,519 patients remained. Exclusions included 3,444 rural nonteaching hospital (NTH) admissions. The final cohort included 3,402 urban NTH and 13,117 urban TH admissions. Chi-square and logistic regression analyzed mortality, cardiogenic shock, ICU admission, AKI, vasopressor use, and blood transfusion, with TH status as the independent variable. Results The study analyzed 16,519 patients with a mortality rate of 3.81%. Mortality was higher in THs (4.05%) than NTHs (2.88%) (p 0.002). Cardiogenic shock occurred in 7.77%, more in THs (9.13%) than NTHs (2.50%) (p 0.001). ICU admission was higher in THs (3.35%) than NTHs (1.52%) (p 0.001). AKI incidence was 29.01%, higher in THs (30.80%) than NTHs (22.10%) (p 0.001). Vasopressor use occurred in 2.81% of patients overall, more in THs (3.26%) than NTHs (1.06%) (p 0.001). Blood transfusions were higher in THs (2.59%) than NTHs (1.73%) (p 0.004). Conclusion Significant differences exist in outcomes between THs and NTHs for heart failure patients, with THs showing more severe presentations, evidenced by higher mortality, cardiogenic shock, ICU admission, AKI, vasopressor use, and transfusions.
