    Abstract:
    Patient readmission within 30 days from discharge has been perceived by the Centers for Medicare and Medical Services as an indicator of poor healthcare quality for specific high-cost medical conditions. Patients who undergo allogeneic hematopoietic cell transplantation (allo-HCT) are often being readmitted. Our study identified the risk factors for 30-day readmission among 618 adult recipients of myeloablative allo-HCT from 1990 to 2009. Two hundred forty-two (39%) of 618 patients (median age = 42 years [range: 18-66]) were readmitted a median of 10 days (range: 1-30) from their hospital discharge. Median duration of readmission was 8 days (range: 0-103). Infections (n = 68), fever with or without identified source of infection (n = 63), gastrointestinal complications (n = 44), graft-versus-host disease (GVHD) (n = 38), and other reasons (n = 29) accounted for 28%, 26%, 18%, 16%, and 12% of readmissions, respectively. During their index admission, patients who were subsequently readmitted had more documented infections (P < .001), higher hematopoietic cell transplantation comorbidity index (HCT-CI) (P < .01), total body irridiation (TBI)-based conditioning (P < .001), unrelated donor (P < .001), and peripheral stem cell (P = .014) transplantation. In multivariable analysis, HCT-CI (odds ratio [OR] = 1.78; 95% confidence interval [CI], 1.25-2.52), TBI-based preparative regimen (OR = 2.63; 95% CI, 1.67-4.13), and infection during admission for allo-HSCT (OR = 2.00; 95% CI, 1.37-2.92) predicted 30-day readmission. Thirty-day readmission itself was an independent predictor of all-cause mortality (hazard ratio [HR](Adj) = 1.66; 95% CI, 1.36-2.10). Our data emphasize the importance of a risk-standardized approach to 30-day hospital readmission if it is used as a quality-of-care metric for bone marrow transplantation.
