Outcome of foreign residents undergoing deceased donor liver transplantation in China: a single-center experience in Taiwan

International Travel for Liver Transplantation: A Comprehensive Assessment of the Impact on the United States Transplant System

BACKGROUND

International travel for transplantation remains a global issue as countries continue to struggle in establishing self-sufficiency. In the United States, the United Network for Organ Sharing (UNOS) requires citizenship classification at time of waitlisting to remain transparent and understand to whom our organs are allocated. This study provides an assessment of patients who travel internationally for liver transplantation and their outcomes using the current citizenship classification used by UNOS.

METHODS

Adult liver UNOS data from 2003 to 2019 were used. Patients were identified as citizens, noncitizen, nonresidents (NCNR), or noncitizen residents (NC-R) according to citizenship status. Descriptive statistics compared demographics among the waitlisted patients and demographics and donor characteristics among transplant recipients. A competing risks model was used to examine waitlist outcomes. The Kaplan-Meier method and Cox proportional hazards were used for posttransplant outcomes.

RESULTS

There were significant demographic differences according to citizenship group among waitlisted (n = 125 652) and transplanted (n = 71 536) patients. Compared with US citizens, NCNR was associated with a 9% increase in transplant (subdistribution hazard ratio [SHR], 1.09; 95% confidence interval [CI], 1.00-1.18; P = 0.04), and NC-R was associated with a 24% decrease in transplant (SHR, 0.76; 95% CI, 0.72-0.79; P < 0.0001) and a 23% increase in death or removal for being too sick (SHR, 1.23; 95% CI, 1.14-1.33; P < 0.0001). US citizens had significantly inferior graft and patient survival (P < 0.001).

CONCLUSIONS

Though the purpose of the citizenship classification system is transparency, the results of this study highlight significant disparities in the access to and outcomes following liver transplantation according to citizenship status.

Intensive care utilization in patients with end-stage liver disease: A population-based comparative study of cohorts with and without comorbid hepatocellular carcinoma in taiwan

BACKGROUND

End-of-life intensive care may be futile and can be a cause of distress to both patients and their families. This study aimed to understand the utilization of intensive care and its associated factors in patients with End-stage liver disease (ESLD) during terminal hospitalization.

METHODS

Population-based retrospective cohort study using the National Health Institute Research Database of Taiwan. All adult patients with ESLD who died during their hospitalization in 2010-2013 were included.

FINDINGS

Of the 14,247 patients with ESLD, the majority (60·8%) was comorbid with hepatocellular carcinoma (HCC). Patients with ESLD only were younger, more deprived, more alcohol-related, and less likely to receive palliative care prior to terminal hospitalization (6·0% vs 29·2% with HCC). Compared to patients with comorbid HCC, relatively more patients without HCC were admitted to ICU (59·6% vs 22·3%), receiving CPR (11·1% vs 4·3%) and mechanical ventilation (36·3% vs 12·5%) during terminal hospitalization. Etiology of alcoholic hepatitis, esophageal varices, septicemia, pneumonia and respiratory failure, and renal failure were associated with a higher probability of ICU admission (adjusted rate ratio (aRR) range: 1·09-2·09). Prior palliative care was associated with lower probability of ICU admission (aRR range: 0·24-0·38).

INTERPRETATION

The intensive care utilization by patients with ESLD in their terminal hospitalization was substantial in Taiwan. Those who are not comorbid with HCC need more attention, especially in terms of their palliative care needs, choices regarding intensive care, and their healthcare utilization.
