Psychological Risk Factors on Hematopoietic Stem Cell Transplantation Patients: Insights From National Readmission...

Psychosocial risk factors (PSRFs) have emerged as important nontraditional risk factors for poor medical outcomes but have not been well-studied in the field of hematopoietic stem cell transplantation (HSCT).

In this study, we retrospectively examined in-hospital and short-term outcomes in patients with PSRFs who underwent HSCT.

We used the National Readmission Database (NRD) to identify patients who underwent HSCT between 2011 and 2020. Patients were stratified based on the presence of either 0 or ≥ 1 PSRFs, which included factors such as mental illness, substance abuse, cognitive problems, a low income level, and an uninsured status. Patients were also classified into allogeneic-HSCT (allo-HSCT) and autologous-HSCT (auto-HSCT) groups. Our primary endpoints were in-hospital and short-term outcomes.

In this nationally representative cohort, 90,747 patients underwent auto-HSCT, while 26,600 patients underwent allo-HSCT. In the auto-HSCT group, individuals with PSRFs exhibited notably higher in-hospital mortality (2.4% vs. 2.8%; p < 0.001) and 30-day all-cause readmission rates (14.4% vs. 17.8%; p < 0.001) compared to those without PSRFs. Similarly, within the allo-HSCT group, patients with PSRFs had significantly higher in-hospital mortality (5.4% vs. 6.4%; p < 0.001) and 30-day all-cause readmission rates (27.3% vs. 31.2%; p < 0.001) compared to those without PSRFs. After adjusting for risk factors, the presence of PSRFs emerged as a substantial predictor for heightened 30-day readmission in allo-HSCT and auto-HSCT.

The presence of PSRFs is correlated with poorer in-hospital and short-term outcomes after both allo-HSCT and auto-HSCT, with a more pronounced effect observed in allo-HSCT. This research underscores the significance of pinpointing high-risk patients and implies support for merging PSRFs after HSCT is beneficial.
