Early Hospital Readmission After Simultaneous Pancreas-Kidney Transplantation: Patient and Center-Level Factors

Area of Science:

• Nephrology
• Transplantation Surgery
• Public Health

Background:

• Early hospital readmission post-transplant increases morbidity, mortality, and healthcare costs.
• Risk factors and incidence of readmission after simultaneous pancreas-kidney transplantation (SPKT) are not well-established.

Purpose of the Study:

• To determine the incidence and patient-level risk factors for early hospital readmission within 30 days following SPKT.
• To investigate the influence of center-level factors on SPKT readmission rates.

Main Methods:

• Analysis of 3643 adult primary first-time SPKT recipients from the United States Renal Data System (1999-2011).
• Modified Poisson regression for patient-level factors; Empirical Bayes statistics for center-level factors.
• Definition of early readmission as hospitalization within 30 days of discharge.

Main Results:

• The incidence of 30-day readmission was 55.5%.
• Increased age (to 40) was associated with lower readmission risk; donor African-American race and longer initial length of stay (up to 14 days) were associated with higher readmission risk.
• No significant association was found between center-level factors and readmission rates.

Conclusions:

• The high incidence of early readmission after SPKT likely reflects patient and graft complexity rather than variations in care quality.
• Identifying modifiable risk factors is crucial for improving post-transplant outcomes and reducing healthcare burdens.
