Purpose: This paper aims to address problems in patient flow and identify the reasons behind extensive wait time at a public liver transplant outpatient clinic in an education and research hospital through the use of Lean health-care theories. Design/methodology/approach: This paper opted for the application of Lean thinking and action research strategy. Data were collected through personal observations, interviews with users and team brainstorming. A value stream map was developed, improvement possibilities were identified and non-value-added activities were attempted to be eliminated. Findings: Significant problems were identified and improvements were implemented and measured. The major remedial measures were: change the scheduling pattern, create a flow chart and a Kanban visual guide for medical students. In addition, an institutional change in the medical appointment scheduling software collaborated in the reduction of time and in the patient’s displacement. The waiting time was reduced by 4.5 h, and the per cent complete and accurate increased by 50 per cent. Practical implications: The flow was redesigned, and a culture of continuous improvement was introduced. Visiting the place where work was being done, leaders identified and created more value to the process without significant costs. The Gemba Walk was a powerful tool, interacting with people and processes in a Kaizen spirit. Originality/value: Public health services in developing countries are one of the most deprived social needs of good practice. It will be useful for those who need examples about how to apply Lean tools in health care.

Several diseases may lead to the need for liver transplantation due to progressive organ damage until the onset of cirrhosis, resulting in changes in interpersonal relationships. Social Support for transplant candidates is an important variable, providing them with psychological and social well-being. This study aims to assess social support in chronic hepatic patients, waiting for liver transplantation. A cross-sectional study was conducted with 119 patients, for convenience sampling, from the liver transplant waiting list at a Brazilian University Hospital Outpatients. The information was collected through semistructured questionnaires, in four stages: 1) socioeconomic and demographic information 2) clinical aspects 3) feelings 4) Social Support Network Inventory (SSNI), to Brazilian Portuguese. The statistical analysis was conducted using ANOVA and multivariate linear regression analysis to evaluate the relationship between the scales of social support and the collected co-variables. Average age was 50.2 ± 11.6, and 87 (73.1%) were men. Patients with alcohol and virus liver disease etiology had the same frequency of 28%. The MELD, without extrapoints, was 16.7 ± 4.9. Global social support family score was 3.72 ± 0.39, and Cronbach’s alpha = 0.79. The multivariate analysis presented the following associations, age = [− 0.010 (95% CI = − 0.010 - -0.010); P = 0.001], etiology of hepatic disease = [− 0.212 (95% CI = − 0.37 - -0.05); P = 0.009], happiness = [− 0.214(95% CI = − 0.33 - -0.09) P = 0.001) and aggressiveness = [0.172 (95% CI = 0.040–0.030); P = 0.010). The social support was greater when the patients were younger (18 to 30 years). Patients with alcoholic cirrhosis, regardless of whether or not they were associated with virus, had less social support. As for feelings, the absence of happiness and the presence of aggressiveness showed a negative effect on social support.

RACIONAL: Utiliza-se o escore MELD (Model End-Stage Liver Disease) para o prognóstico da mortalidade em lista de espera para transplante de fígado e, em alguns estudos, para predição da sobrevida pós-operatória a longo prazo. OBJETIVO: Verificar a aplicação do escore MELD como predição da sobrevida após o transplante. MÉTODOS: Por intermédio de dados coletados prospectivamente efetuou-se um estudo de coorte longitudinal retrospectivo em 232 pacientes. Excluíram-se os retransplantes, insuficiência hepática aguda, crianças e enxertos duplos ou reduzidos. Avaliaram-se os dados dos doadores: idade, sexo, peso, creatinina, bilirrubina, sódio, aspartato aminotransferase, antecedentes pessoais, causa da morte, presença de esteatose, número de critérios expandidos do doador e índice de risco do doador. Em relação aos receptores, analisaram-se as variáveis: sexo, idade, peso, doença hepática, pontos de Child-Turcotte-Pugh, escore MELD, depuração de creatinina, sódio, tempos de isquemia e de hospitalização, quantidade de hemoderivados transfundidos, presença e grau de disfunção do enxerto. A análise estatística foi efetuada usando-se a análise de regressão univariada e/ou múltipla, estatística 'c', teste exato de Fisher, método de Kaplan-Meier (teste log-rank) para sobrevida, e análise de regressão de Cox para risco de óbito ajustado para as condições clínicas. RESULTADOS: O ponto de corte MELD para sobrevida foi 20 e de Child-Turcotte-Pugh foi 11,5. Para escore MELD maior ou igual a 20, os fatores preditivos de sobrevida foram: volume de sangue transfundido, disfunção do enxerto e o sódio do doador. Para os hiponatrêmicos os fatores preditivos de sobrevida foram: volume de sangue transfundido, disfunção do enxerto e sódio do doador. A sobrevida estimada para pacientes com escore MELD >25 foi menor ao final de 12 meses (68,86% vs 39,13%). A sobrevida estimada para os pacientes sem hiponatremia foi maior (65,16% vs 44,44%). A sobrevida aos 5 e 10 anos também seguiu o mesmo padrão. O uso de doadores limítrofes não alterou a sobrevida, mas quando se utilizou o índice de risco do doador observou-se que a sobrevida foi maior para pacientes com índice de risco do doador menor que 1,7 (63,62% vs 53,70%). A associação deste índice com o escore MELD não mostrou diferença estatística em relação à sobrevida. Observou-se que a falência e disfunção do enxerto foram associadas ao número crescente de critérios expandidos do doador. Os receptores de doadores maiores de 50 anos tiveram menor sobrevida (65,58% vs 38,40%) e o escore delta-MELD não discriminou a sobrevida. CONCLUSÃO: A sobrevida dos receptores a curto e longo prazo é associada a escores MELD acima de 25, ao volume de sangue transfundido, à disfunção do enxerto, à hiponatremia, à idade do doador acima de 50 anos e àqueles doadores com índice de risco do doador acima de 1,7.

Hepatocellular carcinoma (HCC) is one of the main indications for orthotopic liver transplantation (OLT). In Brazil, selection criteria for HCC is an expanded version of the Milan Criteria (MC), the so-called "Brazilian Milan Criteria" (BMC). Our aims were to evaluate post-OLT outcomes in patients with HCC and analyze the BMC performance. We conducted a multicenter, retrospective cohort study, analyzing medical records of 1,059 liver transplant recipients with HCC. Tumor was staged according to MC and BMC and correlated with overall survival (OS) and disease-free survival (DFS). We compared the ability of MC and BMC to predict OS and DFS using Delta C-statistic. Post-OLT OS were 63% in five years and HCC recurrence was observed in 8% of patients. At diagnosis, 85% of patients were within MC. Patients within MC at diagnosis and in the explant showed a higher OS and DFS than patients outside MC and within BMC and patients outside both criteria (p < 0.001). Patients outside MC in the explant had an increased risk of tumor recurrence (HR: 3.78; p < 0.001) and poor survival (HR:1.77; p = 0.003). The BMC presented a lower performance than MC in properly classifying patients regarding recurrence risk. In a large Brazilian cohort of HCC patients submitted to liver transplantation, we observed satisfactory overall survival and recurrence rates. However, patients transplanted within the Brazilian expanded criteria had lower OS and DFS when compared to patients within MC, which may generate future discussions regarding the criteria currently used.
