Optimizing immunity against vaccine-preventable diseases improves outcomes in kidney transplant (KT) patients [1, 2, 3]. The American Society for Transplantation (AST) Clinical Practice Guidelines advise that serologic screening for measles, mumps and rubella (MMR) be conducted for all KT candidates, since live-attenuated vaccines are contraindicated post-transplantation [4]. Our team at Mayo Clinic Florida (MCF) conducted a quality improvement (QI) initiative to establish a best MMR screening and immunizations clinical practice in KT candidates using a Plan-Do-Study-Act (PDSA) model. By retrospective chart review of all KT candidates evaluated at our institution from January 1, 2016 to December 31, 2017, baseline data determining the rate of MMR serologic screening was established. PDSA cycles were implemented to adopt protocol-driven testing for MMR serologies, immunization documentation, and vaccination in cases of seronegativity to any of the three MMR viruses in all pre-KT candidates. Two PDSA cycles were completed in 4 months. The study population totaled 447 patients (baseline n=283, PDSA 1 n=61, PDSA 2 n=103). Baseline data showed that 83% (n=235) of pre-KT candidates received infectious disease consultation (IDC). Complete MMR (all three viruses) serological screening in KT candidates improved from baseline 3.9% to 87.4% post-PDSA cycle 2 (P < .001). Necessary immunizations per AST guidelines were ordered in only 41.1% (n=23) of the control cohort versus 100% (n=12) and 96.9% (n=31) of PDSA cycles 1 and 2, respectively (P < 0.001). The data reflect significant practice improvements in MMR screening and immunization rates among KT candidates by using protocol-driven orders combined with our pre-existing IDCs.
