Objective: We evaluated community socioeconomic factors in patients who had unplanned readmission after undergoing proximal aortic surgery (ascending aorta, aortic root, or arch).
Methods: Unplanned readmissions for any reason within 60 days of the index procedure were reviewed by race, acuity at presentation, and gender. We also evaluated 3 community socioeconomic factors: poverty, household income, and education. Kaplan-Meier survival curves were used to assess long-term survival differences by group (race, acuity, and gender).
Results: Among 2339 patients who underwent proximal aortic surgery during the 20-year study period and were discharged alive, our team identified 146 (6.2%) unplanned readmissions. Compared with White patients, Black patients lived in areas characterized by more widespread poverty (20.8% vs 11.1%; P = .0003), lower income ($42,776 vs $65,193; P = .0007), and fewer residents with a high school diploma (73.7% vs 90.1%; P < .0001). Compared with patients whose index operation was elective, patients who had urgent or emergency index procedures lived in areas with lower income ($54,425 vs $64,846; P = .01) and fewer residents with a high school diploma (81.1% vs 89.2%; P = .005). Community socioeconomic factors did not differ by gender. Four- and 6-year survival estimates were 63.1% and 63.1% for Black patients versus 89.1% and 83.0% for White patients (P = .0009). No significant differences by acuity or gender were found.
Conclusions: Among readmitted patients, Black patients and patients who had emergency surgery had less favorable community socioeconomic factors and poorer long-term survival. Earlier and more frequent follow-up in these patients should be considered. Developing off-campus clinics and specific postdischarge measures targeting these patients is important.
