Indocyanine green retention is a potential prognostic indicator after splenectomy and pericardial devascularization for cirrhotic patients

BACKGROUND

Splenectomy and pericardial devascularization (SPD) is an effective treatment of upper gastrointestinal bleeding and hypersplenism in cirrhotic patients with portal hypertension. Indocyanine green retention at 15 minutes (ICGR15) was reported to offer better sensitivity and specificity than the Child-Pugh classification in hepatectomy, but few reports describe ICGR15 in SPD. The present study was to evaluate the prognostic value of ICGR15 for cirrhotic patients with portal hypertension who underwent SPD.

METHODS

From January 2012 to January 2015, 43 patients with portal hypertension and hypersplenism caused by liver cirrhosis were admitted in our center and received SPD. The ICGR15, Child-Pugh classification, model for end-stage liver disease (MELD) score, and perioperative characteristics were analyzed retrospectively.

RESULTS

Preoperative liver function assessment revealed that 34 patients were Child-Pugh class A with ICGR15 of 13.6%-43.0% and MELD score of 7-20; 8 patients were class B with ICGR15 of 22.8%-40.7% and MELD score of 7-17; 1 patient was class C with ICGR15 of 39.7% and MELD score of 22. The optimal ICGR15 threshold for liver function compensation was 31.2%, which offered a sensitivity of 68.4% and a specificity of 70.8%. Univariate analysis showed preoperative ICGR15, MELD score, surgical procedure, intraoperative blood loss, and autologous blood transfusion were significantly different between postoperative liver function compensated and decompensated groups. Multivariate regression analysis revealed that ICGR15 was an independent risk factor of postoperative liver function recovery (P=0.020).

CONCLUSIONS

ICGR15 has outperformed the Child-Pugh classification for assessing liver function in cirrhotic patients with portal hypertension. ICGR15 may be a suitable prognostic indicator for cirrhotic patients after SPD.

Pre-treatment hemodynamic features involved with long-term survival of cirrhotic patients after embolization of gastric fundal varices

PURPOSE

To clarify the pre-treatment hemodynamic features involved in the long-term survival of cirrhotic patients with gastric fundal varices (FV) after balloon-occluded retrograde transvenous obliteration (B-RTO).

MATERIALS AND METHODS

Eighty-one cirrhotic patients with medium- or large-grade FV treated by B-RTO were enrolled in this retrospective study. Pre-treatment flow volume ratio between gastric vein and portal trunk (GP-R) was obtained by Doppler ultrasound.

RESULTS

The cumulative survival rate was 90% at 1 year, 74.8% at 3 years, 57.2% at 5 years, and 45.8% at 7 years without recurrence in a median period of 1148.5 days The survival was poorer in patients with HCC (47% at 3 years, 9.4% at 5 years, p<0.0001) than without (89.2% at 3 years, 81.9% at 5 years, 67.5% at 7 years), in patients with Child B/C (57.7% at 3 years, 42.1% at 5 years, 28.1% at 7 years, p=0.0016) than with Child A (91.8% at 3 years, 71.5% at 5 years, 62.1% at 7 years), and in patients with GP-R > or = 1.0 (58.9% at 3 years, p=0.0485) than with GP-R<1.0 (76.3% at 3 years, 62% at 5 years, 49.6% at 7 years). Multivariate analysis identified the presence of HCC (hazard ratio, 12.486; 95% CI, 4.08-38.216; p<0.0001), Child B/C (hazard ratio, 3.41; 95% CI, 1.594-7.15; p=0.0051) and GP-R > or = 1.0 (hazard ratio, 2.701; 95% CI, 1.07-6.15; p=0.0221) as independent factors for poor prognosis.

CONCLUSION

GP-R > r= 1.0 on Doppler ultrasound before B-RTO may be a predictive indicator for poor prognosis in cirrhotic patients with FV after B-RTO, in addition to the presence of HCC and severe liver damage.

The model for the end-stage liver disease and Child-Pugh score in predicting prognosis in patients with liver cirrhosis and esophageal variceal bleeding

BACKGROUND/AIM

Esophageal variceal bleeding is one of the most frequent and gravest complications of liver cirrhosis, directly life-threatening. By monitoring certain clinical and laboratory hepatocellular insufficiency parameters (Child-Pugh score), it is possible to determine prognosis in patients who are bleeding and evaluate further therapy. Recently, the Model for the End-Stage Liver Disease (MELD) has been proposed as a tool to predict mortality risk in cirrhotic patients. The aim of the study was to evaluate survival prognosis of cirrhotic patients by the MELD and Child-Pugh scores and to analyze the MELD score prognostic value in patients with both liver cirrhosis and variceal bleeding.

METHODS

We retrospectively evaluated the survival rate of a group of 100 cirrhotic patients of a median age of 57 years. The Child-Pugh score was calculated and the MELD score was computed according to the original formula for each patient. We also analysed clinical and laboratory hepatocellular insufficiency parameters in order to examine their connection with a 15-month survival. The MELD values were correlated with the Child-Pugh scores. The Student's t-test was used for statistical analysis.

RESULTS

Twenty-two patients died within 15-months followup. Age and gender did not affect survival rate. The Child-Pugh and MELD scores, as well as ascites and encephalopathy significantly differed between the patients who survived and those who died (p < 0.0001). The International Normalized Ratio (INR) values, serum creatinine and bilirubin were significantly higher, and albumin significantly lower in the patients who died (p < 0.0001). The MELD score was significantly higher in the group of patients who died due to esophageal variceal bleeding (p < 0.0001).

CONCLUSION

In cirrhotic patients the MELD score is an excellent survival predictor at least as well as the Child-Pugh score. Increase in the MELD score is associated with decrease in residual liver function. In the group of patients with liver cirrhosis and esophageal variceal bleeding, the MELD score identifies those with a higher intrahospital mortality risk.

The utility of the model for end-stage liver disease score: a reliable guide for liver transplant candidacy and, for select patients, simultaneous hospice referral

Patients with chronic liver disease are referred late to hospice or never referred. There are several barriers to timely referral. First, liver transplantation (LT) and hospice care have always been perceived as mutually exclusive. Yet the criteria for hospice referral and for LT are more similar than different (for example, advanced liver disease and imminent death). Second, physicians, patients, and families have not had a reliable metric to guide referral. However, many patients wait for transplantation but never receive an organ. We hypothesized that the Model for End-Stage Liver Disease (MELD) score already in use to prioritize LT could be used in selected patients for concurrent hospice referral. Furthermore, we hypothesized that patients awaiting LT can receive hospice care and remain eligible for transplantation. Patients with advanced or end-stage liver disease were referred to the University of California Davis Health System hospice program. We correlated the MELD score at admission to length of stay (LOS) in hospice. A total of 157 end-stage liver disease patients were admitted to the hospice service. At the time of hospice admission the mean MELD score was 21 (range, 6-45). The mean length of hospice stay was 38 days (range, 1-329 days). A significant correlation was observed between hospice LOS and MELD score at hospice admission (P < 0.01). Six patients were offered a liver graft while on the combined (LT and hospice) program. MELD can be used to guide clinician recommendation to families about hospice care, achieving one of the national benchmark goals of increasing hospice care duration beyond the current median of 2-3 weeks. A higher MELD score might augment physician judgment as to hospice referral. Hospice care for selected patients may be an effective strategy to improve the care of end-stage liver disease patients waiting for LT.

Growth hormone-stimulated IGF-1 generation in cirrhosis reflects hepatocellular dysfunction

BACKGROUND/AIMS

Previous studies reported decreased serum IGF-1 levels in cirrhosis. We aimed to correlate GH-stimulated IGF-1 responses with both MELD and Child-Pugh scores and determine the impact of portal hypertension and nutrition on IGF-1 responses.

METHODS

Fifty-three patients (56+/-2 yrs) with cirrhosis were enrolled. Serum IGF-1 levels were measured by RIA before and 24h after a single injection of GH (0.06 mg/kg).

RESULTS

Compared to controls, basal IGF-1 levels were significantly decreased in patients with cirrhosis (17.3+/-6.3 vs 13.6+/-5.1, P<0.001). Increments in IGF-1 levels were significantly lower in cirrhotic patients (controls: 133% vs 49% in MELD score <10, 38% in MELD score 11-18, and 13% in MELD score 19-24, p<0.001). 37% of patients had blunted IGF-1 responses. Increments in IGF-1 levels correlated with albumin (r=0.6), portal congestive index (r=0.4), and MAMC (r=0.25). By multivariate analysis, only CP (OR 5.7) and MELD scores (OR 4.5) accurately differentiated between blunted or non-blunted IGF-1 responses and not portal hypertension (OR 0.9) or malnutrition (OR 1.35).

CONCLUSIONS

Cirrhosis is associated with low IGF-1 levels and an attenuated response to exogenous GH. These findings correlate better with the extent of hepatic dysfunction rather than the presence of portal hypertension or malnutrition.

Higher graft-to-host ratio may decrease posttransplant mortality in patients with a high MELD score

The aim of this study was to determine whether scores from the model for end-stage liver disease (MELD) can be used in the preoperative strategic planning of transplantation surgery. We retrospectively analyzed the outcomes of 62 adult liver transplantation patients whose operation was performed at our center between January 2001 and June 2006. All patients had MELD scores between 8 and 35 with an average value of 20. We compared postoperative mortality among patients who had MELD scores higher than 20 as determined by their graft-to-host ratios. We separately grouped the patients whose graft-to-body weight ratio (GBWR) was equal to or lower than 1 and whose GBWR was higher than 1. The GBWRs associated with mortality after living-donor liver transplantation in the early postoperative period were considered significant (P=.005). MELD scores were also found to be associated with mortality (P=.006). Mortality rates in patients with high MELD scores and a low GBWR were highest among the other combinations. In conclusion, we found that GBWR lower than 1 and MELD score higher than 20 are significant risk factors for mortality after living donor liver transplantation. Patients with low MELD scores can undergo transplantation when their GBWR is lower than 1, but recipients with high MELD scores should receive grafts only when their GBWR is higher than 1.

Prediction of the prognosis in patients with acute-on-chronic hepatitis using the MELD scoring system

AIM

To predict prognosis in patients with acute-on-chronic hepatitis (AOCH) using the model for end-stage liver disease (MELD) scoring system and to study the effects of age, sex, etiology, low serum sodium, and persistent ascites on MELD.

METHODS

The MELD scores of 300 patients with AOCH were calculated according to the original formula. The 3-month mortality in patients was measured, and the validity of the models was determined by means of the concordance (c) statistic. The influential factors on MELD were also assessed.

RESULTS

The 3-month mortality of AOCH patients with a MELD score of 20-29 was 56.0%, with a score of 30-39 it was 76.5%, and with a score over 40 it was 98.2%. The concordance (c) statistic of 3-month mortality was 0.782. Univariate analysis showed that mortality was significantly related to age (P=0.047), etiology (P=0.039), serum sodium (P=0.029) and ascites (P=0.031) for patients with MELD scores 20-29. In multivariate analysis, in patients with MELD scores 20-29, age (P=0.012), etiology (P=0.024), serum sodium (P=0.005) and ascites (P=0.017) were independent predictors of mortality; for MELD scores above 30, only MELD score (P=0.015) was independently predictive.

CONCLUSIONS

The MELD scoring system is a reliable method for predicting mortality in patients with AOCH. In the group with MELD score 20-29, factors including age, etiology, presence of low serum sodium and persistent ascites may influence the MELD scoring system. The MELD score is the decisive predictor of the prognosis of patients with AOCH when the MELD score is over 30.

Influence of hepatic venous pressure gradient on the prediction of survival of patients with cirrhosis in the MELD Era

Measurements of portal pressure, usually obtained via the hepatic venous pressure gradient (HVPG) may be a prognostic marker in cirrhosis. The aim of this study was to evaluate the impact of HVPG on survival in patients with cirrhosis in addition to the Model for End-Stage Liver Disease (MELD) score. We also examined whether inclusion of HVPG in a model with MELD variables improves its prognostic ability. Retrospective analyses of all patients who had HVPG measurements between January 1998 and December 2002 were considered. Proportional hazards Cox models were developed. Prognostic calibrative and discriminative ability of the model was evaluated. In this period, 693 patients had a hepatic hemodynamic study, and 393 patients were included. Survival was significantly worse in those patients with greater HVPG value (univariate HR, 1.05; 95% CI, 1.02-1.08; P = .001). HVPG remained as an independent variable in a model adjusted by MELD, ascites, encephalopathy, and age (multivariate HR, 1.03; 95% CI, 1.00-1.06; P = .05) so that each 1-mmHg increase in HVPG had a 3% increase in death risk. In addition, HVPG as well as MELD score variables and age, significantly contributes to the calibrative predictive capacity of the prognostic model; however, discriminative ability improved only slightly (overall C statistic [95% CI]; MELD score variables: 0.71 [0.62-0.80], MELD score variables, age, and HVPG 0.76: [0.69-0.83]). In conclusion, HVPG has an independent effect on survival in addition to the MELD score. Although inclusion of HVPG and age in a survival predicting model would improve the calibrative ability of MELD, its discriminative ability is not significantly improved.

Impact of MELD on short-term and long-term outcome following liver transplantation: a European perspective

INTRODUCTION

The Model for End-Stage Liver Disease (MELD) has been found to accurately predict pre-transplant mortality and is a valuable system for ranking patients in need of liver transplantation. Its association with post-transplant outcome, however, remains unclear.

MATERIALS AND METHODS

We retrospectively studied 121 adult patients who were transplanted for non-fulminant liver failure between January 1991 and December 2001. MELD scores were calculated taking variables as close as possible prior to liver transplantation. Patients were stratified into two or three groups using different cut-off values of the MELD score.

RESULTS

Indications for liver transplantation were mainly alcoholic liver disease (47.1%) or hepatitis C virus (19.0%). Gender distribution was male 62% vs female 38%. Mean age was 54 years+/-10 years. Mean MELD score was 16+/-6. Follow-up time was 5.4 years (range, 1.6-12.3 years). The use of different MELD cut-off levels yielded no difference in survival at different time points.

CONCLUSION

Higher MELD scores did not have a negative impact on patient and graft survival following OLT. Since MELD is good at identifying those urgently in need of liver transplantation and high MELD scores do not appear to have an influence on long-term outcome, use of MELD in liver allocation seems warranted.

MELD vs Child-Pugh and creatinine-modified Child-Pugh score for predicting survival in patients with decompensated cirrhosis

AIM: Model of End-stage Liver Disease (MELD) score has recently gained wide acceptance over the old Child-Pugh score in predicting survival in patients with decompensated cirrhosis, although it is more sophisticated. We compared the predictive values of MELD, Child-Pugh and creatinine-modified Child-Pugh scores in decompensated cirrhosis.

METHODS: A cohort of 102 patients with decompensated cirrhosis followed-up for a median of 6 mo was studied. Two types of modified Child-Pugh scores estimated by adding 0-4 points to the original score using creatinine levels as a sixth categorical variable were evaluated.

RESULTS: The areas under the receiver operating charac-teristic curves did not differ significantly among the four scores, but none had excellent diagnostic accuracy (areas: 0.71-0.79). Child-Pugh score appeared to be the worst, while the accuracy of MELD was almost identical with that of modified Child-Pugh in predicting short-term and slightly better in predicting medium-term survival. In Cox regression analysis, all four scores were significantly associated with survival, while MELD and creatinine-modified Child-Pugh scores had better predictive values (c-statistics: 0.73 and 0.69-0.70) than Child-Pugh score (c-statistics: 0.65). Adjustment for gamma-glutamate transpeptidase levels increased the predictive values of all systems (c-statistics: 0.77-0.81). Analysis of the expected and observed survival curves in patients subgroups according to their prognosis showed that all models fit the data reasonably well with MELD probably discriminating better the subgroups with worse prognosis.

CONCLUSION: MELD compared to the old Child-Pugh and particularly to creatinine-modified Child-Pugh scores does not appear to offer a clear advantage in predicting survival in patients with decompensated cirrhosis in daily clinical practice.

Preoperative and perioperative predictors of the need for renal replacement therapy after orthotopic liver transplantation

BACKGROUND

Acute renal failure developing after orthotopic liver transplantation (OLTx) requiring renal replacement heralds a poor prognosis. Our center has previously reported a 1-year survival of only 41.8%. We undertook this study to determine whether we could identify preoperative and perioperative factors that would predict which patients are at risk.

METHODS

OLTxs performed between January 1, 1996, and December 31, 2001, were included in our retrospective database review. Combined kidney-liver transplants or patients with preoperative renal replacement therapy (RRT) were excluded. A total of 724 OLTxs were studied, which were divided into group I: no RRT, n=637; group II: hemodialysis only post-OLTx, n=17; and group III: continuous RRT post-OLTx, n=70. Univariate and stepwise logistic multivariate analyses were performed.

RESULTS

Preoperative serum creatinine greater than 1.9 mg/dL (odds ratio [OR] 3.57), preoperative blood urea nitrogen greater than 27 mg/dL (OR 2.68), intensive care unit stay more than 3 days (OR 10.23), and Model for End-Stage Liver Disease score greater than 21 (OR 2.5) were significant. A clinical prediction model was constructed: probability of requiring dialysis posttransplant=(-2.4586+1.2726 [creatinine >1.9] + 0.9858 [blood urea nitrogen >27] + 0.4574 [Model for End-Stage Liver Disease score >21] + 1.1625 [intensive care unit days >3]). A clinical prediction rule for patients with a score greater than 0.12 was applied to OLTx recipients who underwent transplantation in 2002. A total of 15 of 20 patients who received RRT and 111 of 121 who did not were correctly classified with the model.

CONCLUSIONS

This model allowed us to identify patients at high risk for developing the need for RRT postoperatively. Strategies for these patients to prevent or ameliorate acute renal failure and reduce the need for RRT postoperatively are needed.

Liver transplantation for hepatocellular carcinoma: the MELD impact

The new allocation policy of the United Network of Organ Sharing (UNOS) based on the model for end-stage liver disease (MELD) gives candidates with stage T1 or stage T2 hepatocellular carcinoma (HCC) a priority MELD score beyond their degree of hepatic decompensation. The aim of this study was to determine the impact of the new allocation policy on HCC candidates before and after the institution of MELD. The UNOS database was reviewed for all HCC candidates listed between July 1999 and July 2002. The candidates were grouped by two time periods, based on the date of implementation of new allocation policy of February 27, 2002. Pre-MELD candidates were listed for deceased donor liver transplantation (DDLT) before February 27,2002, and post-MELD candidates were listed after February 27, 2002. Candidates were compared by incidence of DDLT, time to DDLT, and dropout rate from the waiting list because of clinical deterioration or death, and survival while waiting and after DDLT. Incidence rates calculated for pre-MELD and post-MELD periods were expressed in person years. During the study, 2,074 HCC candidates were listed for DDLT in the UNOS database. The DDLT incidence rate was 0.439 transplant/person years pre-MELD and 1.454 transplant/person years post-MELD (P < 0.001). The time to DDLT was 2.28 years pre-MELD and 0.69 years post-MELD (P < 0.001). The 5-month dropout rate was 16.5% pre-MELD and 8.5% post-MELD (P < 0.001). The 5-month waiting-list survival was 90.3% pre-MELD and 95.7% post-MELD (P < 0.001). The 5-month survival after DDLT was similar for both time periods. The new allocation policy has led to an increased incidence rate of DDLT in HCC candidates. Furthermore, the 5-month dropout rate has decreased significantly. In addition, 5-month survival while waiting has increased in the post-MELD period. Thus, the new MELD-based allocation policy has benefited HCC candidates.

Pretransplant MELD score as a predictor of outcome after liver transplantation for chronic hepatitis C

The Model of End-Stage Liver Disease (MELD) score, an accurate predictor of mortality in patients awaiting liver transplantation (OLTX), did not predict graft or patient survival in the post-transplant setting. Our aim was to test the model in patients who underwent OLTX for chronic hepatitis C. Two hundred and eighty-seven adult patients who underwent primary OLTX for chronic hepatitis C between December 1993 and September 1999 were studied from a prospectively maintained database. The group was stratified by MELD scores of less than 15, 15-24, and greater than 24. Patient survival, graft survival, and interval liver biopsy pathology were reviewed. Both patient and graft survival at 3, 6, and 12 months were significantly lower in the higher MELD score groups, as was patient survival at 24 months (p-values, 0.01-0.05). The difference in survival between the low, medium, and high MELD score groups increases in time. The survival without bridging fibrosis in the allograft at 1 year post-transplant was significantly lower with higher MELD scores (p = 0.037). The decrease in survival seen in hepatitis C patients with MELD scores greater than 24 raises questions of transplant suitability for these patients. Therapeutic modalities to decrease post-transplant graft injury in these patients should be explored.

A correlation between the pretransplantation MELD score and mortality in the first two years after liver transplantation

The Model for End-Stage Liver Disease (MELD) score is now the criteria for allocation in liver transplantation for patients with chronic disease. Although the score has been effective in the prediction of mortality in patients awaiting liver transplantation, its abilities to predict posttransplantation outcome need study. The aim of this study is to compare outcome in the first 2 years after liver transplantation according to the pretransplantation MELD score. The study includes 669 consecutive patients who underwent primary liver transplantation between December 1993 and October 1999 in a single transplant center. Patients who died of malignancy were excluded from the series. Pretransplantation MELD score was calculated using the United Network for Organ Sharing formula. Patients were stratified according to MELD score less than 15, 15 to 24, and 25 and higher. Posttransplantation survival at 3, 6, 12, 18, and 24 months was significantly lower in the groups with a higher MELD score. The difference was significant for hepatitis C and noncholestatic liver diseases, but not cholestatic diseases. In patients with a MELD score between 15 and 24, survival was significantly greater with cholestatic diseases and lower in patients with hepatitis C. In our study, pretransplantation MELD score correlates with survival in the first 2 years after transplantation. There is a survival advantage for patients with cholestatic diseases compared with those with hepatitis C. These findings suggest the need to readjust MELD score-based allocation decisions to consider patient outcome.

The 1-year and 3-month prognostic utility of the AST/ALT ratio and model for end-stage liver disease score in patients with viral liver cirrhosis

OBJECTIVES

The AST/ALT ratio has shown good diagnostic accuracy in patients with chronic viral liver disease. However, its prognostic utility has never been tested. Recently, the Model for End-Stage Liver Disease (MELD) has been proposed as a simple and effective tool to predict survival in patients with liver cirrhosis. The aims of this study were to assess the 3-month and 1-yr prognostic ability of the AST/ALT ratio in a series of patients with virus-related liver cirrhosis, and to evaluate the relationship between the AST/ALT ratio and the MELD score and to compare their prognostic ability.

METHODS

The AST/ALT ratios and MELD scores of 99 patients with liver cirrhosis of viral etiology (73 patients with hepatitis C virus and 26 with hepatitis B virus) who had been followed-up for at least 1 yr were retrospectively calculated and correlated with the patients' 3-month and 1-yr prognosis. Receiver operating characteristic curves were used to determine the AST/ALT ratio and the MELD score cut-offs with the best sensitivity (SS) and specificity (SP) in discriminating between patients who survived and those who died. Univariate survival curves were estimated by the Kaplan-Meier method using the cut-offs identified by means of receiver operating characteristic curves.

RESULTS

AST/ALT ratios and MELD scores showed a significant correlation (r(s) = 0.503, p = 0.0001). In all, 8% and 30% of the patients had died after 3 months and 1 yr of follow-up, respectively. AST/ALT ratios and MELD scores were significantly higher among the patients who died during both 3-month and 1-yr follow-up. An AST/ALT ratio cut-off of 1.17 had 87% SS and 52% SP, whereas a MELD cut-off of 9 had 57% SS and 74% SP in discriminating between patients who survived and those who died after I yr. The combined assessment of the AST/ALT ratio and/or MELD score had 90% SS and 78% SP. Survival curves of the patients showed that both parameters clearly discriminated between patients who survived and those who died in the short term (AST/ALT ratio, p = 0.0094; MELD score, p = 0.0089) as well as in the long term (AST/ALT ratio, p < 0.0005; MELD score, p = 0.004).

CONCLUSIONS

In patients with virus-related cirrhosis, the AST/ALT ratio has prognostic capability that is not significantly different from that of an established prognostic score such as MELD. Combined assessment of the two parameters increases the medium-term prognostic accuracy.

An examination of factors predicting prioritization for liver transplantation

With the recent transition of the liver transplant allocation system to the Model for End-Stage Liver Disease, a major change is its reliance entirely on objective criteria. In previous reports, potential donor families and members of the transplant community have questioned the fairness of the subjective nature of previous systems. Therefore, we examined the United Network for Organ Sharing database to determine if the previous allocation system benefited a particular group in prioritization for transplant. We included adult patients with chronic liver disease listed for transplant in the year 2000. Patients who had ever been listed as status 2A or 2B were analyzed. A multivariable analysis examined the patient characteristics that predicted being uplisted to status 2A. Of the 9244 patients, 2376 (25.7%) had received a liver transplant as a status 2A or had been listed as status 2A. In the multivariate analysis, the strongest patient characteristics that predicted status 2A were listing in the western United States and shorter duration of registration. Other predictors include blood type O, college education, unemployment, and coverage with private insurance or a health maintenance organization/preferred provider organization. In addition, patients with Laennec's cirrhosis were less likely to be uplisted to status 2A. Age, gender, and race were not predictors of uplisting to status 2A. In conclusion, these data show the wide range of practice patterns with the use of status 2A, and these findings suggest that certain patient groups might have received preference in the previous liver transplant allocation system.

Psychological assessment and care of organ transplant patients

Organ transplant has been developed in animal models over the past 100 years. The major limiting factor in transplant medicine is the shortage of donor organs. This shortage creates pressure for fair and efficient allocation of organs, with expectations that those involved in transplantation will strive to achieve optimal outcomes and ensure just access. This article reviews the major types of transplants and the illnesses and behavioral comorbidities that lead to these procedures, the psychological assessment of transplant candidates, the adaptive tasks required of the transplant recipient at various stages of the transplant process, and relevant psychological interventions. Liaison with others on the transplant team and ethical issues of concern to psychologists who work with transplant patients, including living organ donors, are also discussed. Finally, new developments in transplant and suggestions for future psychological research in organ transplant are presented.
