Background: The STEPP group was established to investigate factors that affect long-term transplant outcomes including quality of life and other patient-reported outcomes between different transplant centers and patients. Methods: Data were collected for 2,650 patients whose first renal transplant took place between 1992 and 2003 in five UK centers. Univariable and multivariable survival analyses were performed using eleven candidate explanatory variables. Results: Graft survival was worse in Black (B) patients (HR B v W 1.57 95% CI 1.10, 2.24), and in South Asian (A) patients (HR A v W 1.39 95% CI 1.03, 1.85) compared to Whites (W) after adjusting for other factors including HLA mismatch, and time on dialysis. Time spent on dialysis pre-transplantation was non-linearly associated with patient, but not death-censored graft survival. Losing a functioning graft was a strong predictor of patient death. One site had both the best graft and the worst patient survival. Conclusions: Differences in patient and graft survival between ethnic groups cannot be explained by currently recognized factors. These, and the complex balance between optimum patient and graft survival which differs between sites in this study require further investigation.

Background: Post-transplant hypertension is a major modifiable risk factor for graft and patient survival. The aim of this study was to establish independent predictors for achieving systolic, diastolic and overall blood pressure target [Kidney Disease Outcome Quality Initiative (K/DOQI) target blood pressure Methods: The most recent office blood pressure readings were collected for 513 RTRs at least 6 months after transplantation. In addition, demographic data, comorbidities, medications prescribed, weight, duration of transplantation, and laboratory parameters were recorded. Logistic regression analysis was used to determine whether any covariables were significant (p < 0.05) independent predictors of controlled blood pressure (Results: Approximately 50% of the RTRs had blood pressures Conclusions: This study shows that improvements in blood pressure control can be achieved. People with diabetes were 2.1 times more likely to meet target blood pressure. Further improvements in blood pressure control may require different treatment strategies in addition to the current pharmacological approach.
