Complications, length of stay, and cost of cholecystectomy in kidney transplant recipients.

ABSTRACT: We hypothesized that cholecystectomy may be riskier for kidney transplant recipients (KTR) given their lifelong immunosuppression, physiologic impact of renal failure, and increased risk of gallstone and biliary disease. Using NIS, we compared mortality, morbidity, length of stay and cost in KTR vs non-KTR following cholecystectomy in the US from 2000 to 2011, adjusting for patient and hospital level factors, including transplant center status. Mortality was higher (OR 2.4), morbidity was higher (OR 1.3), LOS was longer (ratio 1.2), and costs were greater (ratio 1.1) for KTR compared to non-KTR following cholecystectomy. While it is clear that KTR are a high risk group following cholecystectomy, the cause of this increased risk requires further investigation.

Project description:BackgroundSurgical site complications (SSCs) are an important source of morbidity after kidney transplantation. We assessed the incidence, risk factors, outcomes and economic impact of SSCs in a large, diverse population of kidney transplant recipients.MethodsWe conducted a single-centre, observational cohort study of adult (age ≥ 18 yr) patients who underwent kidney transplantation between Jan. 1, 2005, and Dec. 31, 2015, with a minimum of 1 year of follow-up. Cases of SSC, including infections and wound dehiscence, were determined from patient records. Inpatient and outpatient hospital costs were determined 6 and 12 months after transplantation. We used the Kaplan-Meier product-limit method to determine the cumulative probability of SSCs and other outcomes. We evaluated risk factors and clinical outcomes using Cox proportional hazard ratios. Linear regression models were used to study the effect of SSCs on graft function.ResultsThe incidence rate of SSCs within 30 days after transplantation was 4.19 per 100 person-months. The cumulative probability of developing an SSC within 30 days after transplantation was 4.13% (95% confidence interval [CI] 3.23%-5.28%). Increased recipient body mass index (BMI) (hazard ratio [HR] 1.07, 95% CI 1.02-1.11), longer cold ischemic time (HR 1.05, 95% CI 1.01-1.09) and transplantation in 2010-2012 versus 2005-2009 (HR 2.20, 95% CI 1.19-4.04) were risk factors for SSC development. In multivariable stepwise Cox proportional hazard models, SSC was a significant risk factor for death-censored graft failure (HR 3.08, 95% CI 1.60-5.90) and total graft failure (HR 2.09, 95% CI 1.32-3.32). Cumulative median hospital costs were $2238.46 greater for patients with an SSC than for those without.ConclusionIncreased BMI, longer cold ischemic time and the 2010-2012 transplantation period predisposed to SSCs. The development of SSCs was associated with a higher risk of graft failure. Strategies to minimize SSCs may improve outcomes after kidney transplantation and reduce costs.
