Background: Hospital readmission (HR) after surgery is considered a quality metric. Methods: Data on 2371 first-time adult kidney transplant (KT) recipients were collected to analyze the “early” (≤30 days) and “late” (31-365 days) HR patterns after KT at a single center over a 12-year time span (2002-2013). Results: 30-day, 90-day, and 1-year HR were 31%, 41%, and 53%, respectively. Risk factors for HR included age >50, female sex, black race, BMI >30, transplant LOS >5 days, and pre-transplant time on dialysis >765 days. Indications for early (n = 749) and late (n = 508) HR were similar. Early HR (OR: 3.80, P =.007) and black race (OR: 2.38, P =.009) were associated with higher odds of 1-year graft failure while frequency (1-2, 3-4, 5+) of HR (ORs: 4.68, 8.36, 9.44, P <.001) and age > 50 (OR: 2.11, P =.007) were associated with higher odds of 1-year mortality. Transplant LOS > 5 days increased both odds of 1-year graft failure (OR: 3.51, P =.001) and mortality (OR: 2.05, P =.006). One-year graft and recipient survival were 96.7% and 94.8%, respectively. Conclusions: Hospital readmission was associated with reduced graft and patient survival; however, despite a relatively high and consistent HR rate after KT, overall 1-year graft and patient survival was high.
