Purpose: Post-transplant lymphoproliferative disorder (PTLD) is a serious complication after kidney transplant. In a prior analysis using Medicare claims database from 1995 to 2003, the 1-year incidence rate for PTLD was 0.46 per 100 person-years with 95% CI: 0.39-0.53 (Kasiske, et al, 2011). Using 2 US insurance claims databases, this study examined the changes in the risk of PTLD in patients with kidney transplant over recent years. Methods: A total of 7,796 kidney transplant recipients in Truven Health MarketScan (cohort 1) and 5,466 in PharMetrics (cohort 2) were included in this analysis. The ascertainment of PTLD case was based on ICD-9-CM codes for PTLD and B-cell lymphoma in the claims records. The incidence rates of PTLD by 1 year post-transplantation and 95% CIs were estimated by calendar year in each cohort. Results: In the claims database cohorts between Jan 2008 and July 2011, the incidence rates of PTLD by 1 year post-transplant demonstrated a trend towards increase from 0.33-0.46 per 100 person-years in 2008-2009 to 0.73-0.78 per 100 person-years in 2010-2011.
