The impact of a standardized disease management program on race/ethnicity and gender disparities in care and mortality.

Background: Data on racial and gender differences in mortality in patients followed in a standardized heart failure disease management program (HFDMP) are scarce.
Methods: Survival was calculated by race/ethnicity and gender for 837 patients enrolled in a HFDMP. (The patients studied were indigent African American and White outpatients [39% African American, 36% female] enrolled into at Leonard J. Chabert Medical Center in Houma, Louisiana.) The hazard ratio associated with demographic and clinical characteristic individually and as a whole, was estimated for the four groups.
Results: White males had the highest mortality (African American female: HR=0.64, African American male: HR=0.65, White female: HR=0.67, p<.05). Age (HR=1.04, p<.001), ejection fraction (HR=0.97, p<.001), New York Heart Association (NYHA) (HR=1.57, p<.001), systolic blood pressure (HR=0.99, p<.05), hematocrit (HR=0.96, p<.01), diabetes (HR=0.98, p<.05), and body mass index (HR=0.98, p<.05) were significant predictors of mortality in the univariate model. Age (HR=1.04, p<.001), NYHA (HR=1.40, p<.001), diabetes (HR=2.52, p<.001), and White female (HR=.44, p<.01) were significant predictors of mortality in the multivariate model.
Conclusion: With the exception of White females, who demonstrated lower mortality, amongst African American males and females and White males who participated in a HFDMP no difference in survival was observed.
