Abstract 18108: Hospitalized Heart Failure Patients of Native American, Pacific Islander, Asian, Hispanic, and African American Background Have Significantly Different Baseline Characteristics and Outcomes Compared With White Patients
Introduction: Racial differences in heart failure (HF) hospitalization characteristics and outcomes between white and African American (AA) populations have been described previously. However there remains a paucity of information regarding other major race groups, particularly Native American (NA), Asian, and Pacific Islanders (PI). We analyzed HF hospitalization within these race groups with the objective to identify differences in baseline characteristics and outcomes.
Methods: Over 134.5 million administrative hospital records between 1994-2013 were screened for a primary diagnosis of HF using ICD-9 code 428. Outcomes included death, discharge home (including with home health), and skilled nursing facility (SNF). Risk factor associations with death and disposition home vs SNF/intermediate care were identified using multivariable logistic regression adjusted for age, gender, and several common comorbid conditions.
Results: A total of 4,628,725 HF hospitalizations were identified. Of these 3,031,810 identified as white, 770,339 as AA, 83,627 as Asian, 12,024 as Native American, and 2,862 as Pacific Islander. Similar to white patients (med. age 79 years), Asians were older (med. 77 years) whereas NAs (med. 67 years), PIs (med. 72 years), and AAs (med. 64 years) were younger (p<0.001 for all). Sex differences were most notable in NAs with 64% male and 36% female compared to an even distribution among other races (45-55% male). White and PI patients had the highest likelihood of death followed by Asian, Hispanic, NA, and AA patients (p<0.001 for all except PI, Figure 1). Among patients surviving to discharge, white and PI patients were least likely to be discharged home, followed by AA, NA, Asian, and Hispanic patients in increasing order (p<0.001 for all except PI).
Conclusion: There are notable differences in patient characteristics and outcomes among hospitalized NA, Asian, PI and Hispanic patients compared with white and AAs.
