Abstract P369: Hospital Outcomes of Hypertensive Emergency in Black and White Patients.

Abstract

Objectives: A rapid and severe increase in blood pressure resulting in new or progressive end-organ damage is defined as a hypertensive emergency. Our study sought to estimate the clinical outcomes of black and white patients admitted for hypertensive emergency. Methods: Using the National Inpatient Sample Database of 2020 (NIS), retrospective data of black and white patients who were admitted for hypertensive emergency were identified using ICD-10 codes. Outcomes were in-hospital mortality, cerebrovascular accident (CVA), acute kidney injury (AKI), myocardial infarction (MI), pulmonary edema, acute hypoxic respiratory failure, length of hospital stay, and total hospital charges. Results: A total of 59690 patients were admitted for hypertensive emergency. 80.6% of patients were either black or white. Black patients were younger (54 years, 95% CI 54 – 55 VS 65 years, 95% CI 65 – 65) when compared to white patients. There were no statistically significant differences in inpatient mortality (p=0.2345), myocardial infarction (p=0.8618), and pulmonary edema (p=0.8835). Black patients had increased acute kidney injury (p<0.0001), acute hypoxic respiratory failure (p=0.0014), length of hospital stays (4 days, 95% CI 4 – 5 VS 3 days, 95% CI 3 – 4), and total hospital charges ($47,132.68, 95% CI $44,808.58 - $49,456.79 VS $43,882.58, 95% CI $42,394.76 - $45,370.39). White patients had increased cerebrovascular accident (p<0.0001) when compared to black patients. Conclusion: Per this study, there was no difference in in-hospital mortality between black and white patients admitted for hypertensive emergency. Black patients had increased AKI, acute hypoxic respiratory failure, length of hospital stays, and charges.
