Early hospital readmission after kidney transplantation under a public health care system.

Early hospital readmission (EHR) is associated with increased mortality after kidney transplantation. This is influenced by population demographics and the comprehensiveness of the healthcare system. We investigated the incidence and risk factors associated with EHR and 1-year patient and graft survivals. METHODS: We included all recipients of kidney transplant between 2011 and 2012. We excluded recipients younger than 18 years, retransplants and who died or lost the graft during the index hospital admission. RESULTS: Among 1175 recipients, the incidence of EHR was 26.6%. The main reasons for EHR were infection (67%), surgical complications (14%), and metabolic disturbances (11%). Independent risk factors associated with EHR were recipient age (OR = 1.95, 95% CI 1.46-2.63, P < 0.001), CMV serology negative (OR = 2.2, 95% CI 1.31-3.65, P = 0.003), use of rabbit anti-thymocyte globulin (OR = 2.06, 95% CI 1.33-3.13, P < 0.001), treatment for acute rejection during index hospitalization (OR = 1.68, 95% CI 1.15-2.47, P = 0.008), and length of stay (OR = 1.72, 95% CI 1.18-2.5, P = 0.005). Patient (88.8% vs 97.6%, P < 0.001) and death-censored graft (97.4% vs 99.0%, P < 0.001) survivals were inferior comparing patients with and without EHR. Conclusion EHR was independently associated with mortality (OR 4.01, 95% CI 2.13-7.54, P < 0.001), but its incidence and causes are directly related to the local characteristics of the population and healthcare system.

Use of mTOR inhibitor as prophylaxis for cytomegalovirus disease after kidney transplantation: A natural experiment.

OBJECTIVES: To describe the incidence of cytomegalovirus (CMV) infection/disease in kidney transplant recipients receiving an mTOR-inhibitor-containing immunosuppressive regimen without prophylactic CMV treatment. METHODS: This single-center retrospective cohort analysis included all de novo kidney transplant recipients (09/15/2015-07/31/2017) receiving 3 mg/kg single dose of rabbit antithymocyte globulin induction, tacrolimus, everolimus, and prednisone. Preemptive therapy was initiated only in patients deemed at higher risk for CMV infection: (a) D+/R- CMV patients; (b) after treatment for acute rejection (ARt); and (c) after everolimus discontinuation (EVRd). RESULTS: Of 230 patients, there were no episodes of CMV disease among 217 (94%) without criteria to initiate preemptive therapy. Of 77 (33.5%) patients initiating preemptive therapy, 13 were D+/R-, 30 were ARt, and 34 were EVRd. The overall incidence of first CMV infection/disease was 6% (46.1% in D+/R-, 13.3% ARt [all patients had also discontinued everolimus], and 11.8% after early [<90 days] EVRd). The incidence of biopsy-proven acute rejection was 5.6%, and median glomerular filtration rate at month 12 was 47 mL/min/1.73m2 . One-year patient and death-censored graft survivals were 97.4% and 98.1%. CONCLUSION: This study suggests that everolimus-containing immunosuppressive regimen reduces the need for preventive strategies for CMV infection in the majority of kidney transplant recipients, reducing antiviral drug-associated toxicities and healthcare-related expenditures.

The impact of universal induction therapy on early hospital readmission of kidney transplant recipients.

BACKGROUND: Early hospital readmission (EHR) is associated with worse outcomes. The use of anti-thymocyte globulin (rATG) induction therapy is associated with increased efficacy in preventing acute rejection, although safety concerns still exist. METHODS: This retrospective single-center study compared the incidence, causes of EHR, and one-year clinical outcomes of patients receiving a kidney transplant between August 18, 2011 and December 31, 2012 (old era), in which only high-risk patients received 5 mg/kg rATG, with those transplanted between August 18, 2014 and December 31, 2015 (new era), in which all patients received a single 3 mg/kg dose of rATG. RESULTS: There were 788 patients from the Old Era and 800 from the New Era. The EHR incidence in the old era patients was 26.4% and in the new era patients, 22.5% (p = 0.071). The main cause of EHR in both eras was infection (67% vs. 68%). The incidence of acute rejection episodes was lower (22.7% vs 3.5%, p < 0.001) and the one-year patient survival was higher (95.6% vs. 98.1%, vs. p = 0.004) in new era patients. CONCLUSION: The universal use of 3 mg/kg rATG single-dose induction therapy in the new era was associated with a trend towards reduced EHR and a reduction in the incidence of acute rejection and mortality.

Early Hospital Readmission (EHR) in kidney transplantation: a review article.

Early hospital readmission (EHR), defined as all readmissions within 30 days of initial hospital discharge, is a health care quality measure. It is influenced by the demographic characteristics of the population at risk, the multidisciplinary approach for hospital discharge, the access, coverage, and comprehensiveness of the health care system, and reimbursement policies. EHR is associated with higher morbidity, mortality, and increased health care costs. Monitoring EHR enables the identification of hospital and outpatient healthcare weaknesses and the implementation of corrective interventions. Among kidney transplant recipients in the USA, EHR ranges between 18 and 47%, and is associated with one-year increased mortality and graft loss. One study in Brazil showed an incidence of 19.8% of EHR. The main causes of readmission were infections and surgical and metabolic complications. Strategies to reduce early hospital readmission are therefore essential and should consider the local factors, including socio-economic conditions, epidemiology and endemic diseases, and mobility.

Resumo Histórico: A Readmissão Hospitalar Precoce (RHP) está associada a piores desfechos. O uso de terapia de indução com globulina antitimócito (rATG, por sua sigla em inglês) está associado ao aumento da eficácia na prevenção de rejeição aguda, embora ainda existam preocupações quanto à segurança. Métodos: Este estudo retrospectivo de centro único comparou a incidência, as causas da RHP e os desfechos clínicos de um ano de pacientes que receberam transplante renal entre 18 de Agosto de 2011 e 31 de Dezembro de 2012 (Antiga Era), em que apenas pacientes de alto risco receberam 5 mg/kg de rATG, com aqueles transplantados entre 18 de Agosto de 2014 e 31 de Dezembro de 2015 (Nova Era), em que todos os pacientes receberam uma única dose de 3 mg/kg de rATG. Resultados: Houve 788 pacientes da Antiga Era e 800 da Nova Era. A incidência de RHP nos pacientes da antiga era foi de 26,4% e nos pacientes da nova era, 22,5% (p = 0,071). A principal causa de RHP em ambas as eras foi infecção (67% vs. 68%). A incidência de episódios de rejeição aguda foi menor (22,7% vs. 3,5%; p < 0,001) e a sobrevida do paciente em um ano foi maior (95,6% vs. 98,1%; vs. p = 0,004) em pacientes da nova era. Conclusão: O uso universal de terapia de indução de 3 mg/kg de rATG em dose única na nova era foi associado a uma tendência à redução da RHP e a uma redução na incidência de rejeição aguda e mortalidade.

Among kidney transplant recipients in the USA, EHR ranges between 18 and 47%, and is associated with one-year increased mortality and graft loss. One study in Brazil showed an incidence of 19.8% of EHR. The main causes of readmission were infections and surgical and metabolic complications.

Resumo A Readmissão Hospitalar Precoce (RH), definida como todas as readmissões dentro de 30 dias após a alta hospitalar inicial, é uma métrica da qualidade hospitalar. É influenciada pelas características demográficas da população em risco, pela abordagem multidisciplinar da alta hospitalar inicial, pelo acesso, pela cobertura e pela abrangência do Sistema de Saúde e pelas políticas de reembolso. A readmissão hospitalar precoce está associada a maior morbidade, mortalidade e aumento dos custos com saúde. O monitoramento da RH permite a identificação das fragilidades hospitalares e ambulatoriais e a implementação de intervenções corretivas. Entre os receptores de transplante renal nos EUA, a RH varia entre 18% e 47% e está associada a maior mortalidade e perda do enxerto no primeiro ano do transplante. Um estudo no Brasil mostrou uma incidência de 19,8% de RH. As principais causas de readmissão foram infecções e complicações cirúrgicas e metabólicas. As estratégias para reduzir a readmissão hospitalar precoce são, portanto, essenciais e devem considerar o ambiente local, incluindo condições socioeconômicas, epidemiologia local, doenças e mobilidade endêmicas.
