Abstract Background Vaccine-preventable diseases account for significant morbidity and mortality in the kidney transplant (KT) patient population. AST Guidelines support review and documentation of pneumococcal vaccines in KT candidate infectious disease (ID) evaluations. The objective of this study is to determine the number of KT candidates screened for prior pneumococcal immunizations and the frequency of vaccines ordered by providers when indicated at Mayo Clinic Florida’s (MCF) Transplant Center. Methods This study was an institution-based retrospective analysis of all KT candidates evaluated at MCF from December 2, 2019 – January 14, 2020. Data collection was obtained by electronic health record review. Outcomes included known history and documentation rates of prior pneumococcal vaccinations (both Prevnar 13 and Pneumovax 23) by infectious disease (ID) providers, as well as pneumococcal vaccine order frequency during ID pre-transplant evaluation when indicated. Data analysis was done using simple descriptive statistics. Results Sixty-one patients underwent KT evaluation during the study period. Among the 61 patients, 20 (32.8%) and 20 (32.8%) had a known prior history of receiving Prevnar 13 and Pneumovax 23 vaccinations, respectively. Vaccine history was unknown for Prevnar 13 and Pneumovax 23 in 39 (63.9%) patients. Vaccine status was not documented by ID providers in 2 (3.3%) patients. When appropriate, ID providers ordered Prevnar 13 and Pneumovax 23 in 38 (92.7%) and 41 (100%) patients, respectively. Orders included both electronic and written documentation to account for patients planning immunization elsewhere. Of the 38 patients advised to receive the Prevnar 13 vaccine, 17 (41.5%) patients were documented completing immunization. Pneumovax 23 order completion rates were not recorded since the study period only lasted six weeks due to closure by COVID-19. Table 1. Pneumococcal Vaccine History Documentation Rates Obtained by Patient Recall or Records Table 2. Pneumococcal Vaccine Order Rates at Pre-Kidney Transplant Consultations Table 3. Prevnar 13 Order Completion Rate by Documentation Conclusion The data reflect a high number of patients who either do not recall or have documentation of prior pneumococcal vaccination available at time of KT ID evaluation. Providers documented history of pneumococcal vaccinations extremely well, ordering immunizations when necessary. This study highlights lack of portability of immunization histories in a given patient population and opportunity for improved care. Disclosures Claudia R. Libertin, MD, Pfizer, Inc.

Establishing best practices in measles, mumps, and rubella serologic screening for kidney transplant candidates
AbstractOptimizing immunity against vaccine‐preventable diseases improves outcomes in kidney transplant (KT) patients (Arora et al,World J Transplant, 2019, 9:1; Sester et al,Transplant Rev, 2008, 22:274; Fishman,N Engl J Med, 2007, 357:2601). The American Society for Transplantation (AST) Clinical Practice Guidelines advises that serologic screening for measles, mumps, and rubella (MMR) be conducted for all KT candidates, since live‐attenuated vaccines are contraindicated post‐transplantation (Malinis et al,Clin Transplant, 2019, 33:e13548). 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%‐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 vs 100% (n = 12) and 96.9% (n = 31) of PDSA cycles 1 and 2, respectively (P < .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.
Predictors of disease severity and outcome of hospitalized renal transplant recipients with COVID-19 infection: a systematic review of a globally representative sample
Abstract Introduction. COVID-19 presents a special challenge to the kidney transplant population. Methods. A systematic review of articles that examined COVID-19 in kidney transplant recipients was performed. Patients’ demographics, clinical, laboratory and radiological presentations, immunosuppression modification, and COVID-19 specific management were abstracted and analyzed. COVID-19 severity was classified into mild, moderate, and severe. Disease outcome was classified by whether the patient was discharged, still hospitalized, or died. Results. 44 articles reporting individual data and 13 articles reporting aggregated data on 149 and 561 kidney transplant recipients respectively with COVID-19 from Asia, Europe and America fulfilled all inclusion and exclusion criteria. Among studies reporting case specific data, 76% of cases had severe disease. Compared to patients with mild/moderate disease, patients with severe disease had higher CRP, LDH, Ferritin, D-dimer and were more likely to have bilateral lung involvement at presentation and longer time since transplantation (P < 0.05 for all). Recipients’ age, gender and comorbidities did not impact disease severity. Patients with severe disease had a more aggressive CNI reduction and more antiviral medications utilization. Outcome was reported on 145 cases, of those 34 (23%) died all with severe disease. Longer duration from transplant to disease diagnosis, hypoxia and higher LDH were associated with mortality (P < 0.05). Different immunosuppression reduction strategies, high dose parenteral corticosteroids use and various antiviral combinations did not demonstrate survival advantage. Similar finding was observed for studies reporting aggregated data. Conclusion. COVID-19 in kidney transplant patients is associated with high rate of disease severity and fatality. Higher LDH and longer time since transplantation predicted both disease severity and mortality. None of the COVID-19 specific treatment correlated with, or improved disease outcome in kidney transplant recipients.
A Systematic Review of Opt‐out Versus Opt‐in Consent on Deceased Organ Donation and Transplantation (2006–2016)
AbstractBackgroundSignificant numbers of patients in the USA and UK die while waiting for solid organ transplant. Only 1–2% of deaths are eligible as donors with a fraction of the deceased donating organs. The form of consent to donation may affect the organs available. Forms of consent include: opt‐in, mandated choice, opt‐out, and organ conscription. Opt‐in and opt‐out are commonly practiced. A systematic review was conducted to determine the effect of opt‐in versus opt‐out consent on the deceased donation rate (DDR) and deceased transplantation rate (DTR).MethodsLiterature searches of PubMed and EMBASE between 2006 and 2016 were performed. Research studies were selected based on certain inclusion criteria which include USA, UK, and Spain; compare opt‐in versus opt‐out; primary data analysis; and reported DDR or DTR. Modeled effect on US transplant activity was conducted using public data from Organ Procurement and Transplantation Network and Centers for Disease Control WONDER from 2006 to 2015.ResultsA total of 2400 studies were screened and six studies were included. Four studies reported opt‐out consent increases DDR by 21–76% over 5–14 years. These studies compared 13–25 opt‐out countries versus 9–23 opt‐in countries. Three studies reported opt‐out consent increases DTR by 38–83% over 11–13 years. These studies compared 22–25 opt‐out versus 22–28 opt‐in countries. Modeled opt‐out activity on the USA resulted in 4753–17,201 additional transplants annually.ConclusionOpt‐out consent increases DDR and DTR and may be useful in decreasing deaths on the waiting list in the USA and other countries.Registration numberPROSPERO CRD42019098759.
