Disease classification: a pitfall of the ERA/EDTA registry?

摘要

We read with great interest the expert editorial comment by Prof. Ronco [1] which discussed the paper by Tsakiris et al. on the incidence and outcome of patients starting renal replacement therapy for end-stage renal disease due to multiple myeloma (MM) or light-chain deposit disease (LCDD) using long-term data from the ERA-EDTA Registry [2]. Prof. Ronco noted the lack of diagnostic detail available in the existing ERA-EDTA Primary Renal Diagnosis (PRD) codes, and he gave constructive suggestions for the subclassification of diseases currently included in PRD code 82, which includes MM and LCDD.
