Economic evaluation of kidney transplantation versus hemodialysis in patients with end-stage renal disease in Hungary

The Magnitude of the Health and Economic Impact of Increased Organ Donation on Patients With End-Stage Renal Disease

Objectives. There are several approaches such as presumed consent and compensation for deceased donor organs that could reduce the gap between supply and demand for kidneys. Our objective is to evaluate the magnitude of the economic impact of policies to increase deceased donor organ donation in the United States. Methods. We built a Markov model and simulate an open cohort of end-stage renal disease patients awaiting kidney transplantation in the United States over 20 years. Model inputs were derived from the United States Renal Data System and published literature. We evaluate the magnitude of the health and economic impact of policies to increase deceased donor kidney donation in the United States. Results. Increasing deceased kidney donation by 5% would save $4.7 billion, and gain 30,870 quality-adjusted life years over the lifetime of an open cohort of patients on dialysis on the waitlist for kidney transplantation. With an increase in donations of 25%, the cost saved was $21 billion, and 145,136 quality-adjusted life years were gained. Policies increasing deceased kidney donation by 5% could pay donor estates $8000 or incur a onetime cost of up to $4 billion and still be cost-saving. Conclusions. Increasing deceased kidney donation could significantly impact national spending and health for end-stage renal disease patients.

THE COST OF KIDNEY TRANSPLANTATION AT THE MERKUR UNIVERSITY HOSPITAL, ZAGREB, CROATIA

The aim was to determine the cost of hospitalization for a transplant procedure and identify the independent variables associated with the cost of transplantation. The investigation was designed as a retrospective single-center cohort study conducted at a tertiary university hospital transplant center in Zagreb, Croatia. The study included 219 consecutive kidney recipients transplanted during the 2007-2013 period at the Merkur University Hospital. There were 141 male and 78 female patients having undergone kidney transplantation during the study period. The majority of kidney transplants were from a deceased donor (n=179), while 40 were from a living donor. The mean cost of a transplantation was 86,140±42,240 HRK (11,460±5,600 €), ranging from 29,000 HRK (3,860 €) to 408,000 HRK (54,000 €). In the bivariate analysis, the variables associated with the cost of transplantation were the length of hospital stay, delayed graft function, death of the patient, graft loss, use of steroids, and death-censored graft loss. In the multivariate analysis, delayed graft function was the only statistically significant variable for the cost of transplantation. Since only delayed graft function had an impact on the cost of transplantation in this study, certain steps such as shortening of the cold ischemia time (better organization of organ transport), better education of family members for living donors, and higher percentage of patients on peritoneal dialysis should be taken to lower the percentage of delayed graft function.

Cost-effectiveness of Deceased-donor Renal Transplant Versus Dialysis to Treat End-stage Renal Disease: A Systematic Review

Supplemental Digital Content is available in the text.

Deceased-donor renal transplant (DDRT) is an expensive and potentially risky health intervention with the prospect of improved life and lower long-term costs compared with dialysis. Due to the increasing shortage of kidneys and the associated rise of transplantation costs, certain patient groups may not benefit from transplantation in a cost-effective manner compared with dialysis. The objective of this systematic review was to provide a comprehensive synthesis of evidence on the cost-effectiveness of DDRT relative to dialysis to treat adults with end-stage renal disease and patient-, donor-, and system-level factors that may modify the conclusion. A systematic search of articles was conducted on major databases including MEDLINE, Embase, Scopus, EconLit, and the Health Economic Evaluations Database. Eligible articles were restricted to those published in 2001 or thereafter. Two reviewers independently assessed the suitability of studies and excluded studies that focused on recipients with age <18 years old and those of a living-donor or multiorgan transplant. We show that while DDRT is generally a cost-effective treatment relative to dialysis at conventional willingness-to-pay thresholds, a range of drivers including older patient age, comorbidity, and long wait times significantly reduce the benefit of DDRT while escalating healthcare costs. These findings suggest that the performance of DDRT on older patients with comorbidities should be carefully evaluated to avoid adverse results as evidence suggests that it is not cost-effective. Delayed transplantation may reduce the economic benefits of transplant which necessitates targeted policies that aim to shorten wait times. More recent findings have demonstrated that transplantation using high-risk donors may be a cost-effective and promising alternative to dialysis in the face of a lack of organ availability and fiscal constraints. This review highlights key concepts of health economic evaluations and the relevance of cost-effectiveness to inform care and decision-making in renal programs.

A cost analysis of kidney replacement therapy options in Palestine

This study provides a cost analysis of kidney replacement therapy options in Palestine. It informs evidence-based resource allocation decisions for government-funded kidney disease services where transplant donors are limited, and some of the common modalities, i.e., peritoneal dialysis (PD) and home hemodialysis (HD), are not widely available due to shortages of qualified staff, specialists, and centers to follow the patient cases, provide training, make home visits, or provide educational programs for patients. The average cost of kidney transplant was US$16,277 for the first year; the estimated cost of HD per patient averaged US$16,085 per year--nearly as much as a transplant. Consistent with prior literature and experience, while live, related kidney donors are scarce, we found that kidney transplant was more adequate and less expensive than HD. These results have direct resource allocation implications for government-funded kidney disease services under Palestinian Ministry of Health. Our findings strongly suggest that investing in sufficient qualified staff, equipment, and clinical infrastructure to replace HD services with transplantation whenever medically indicated and suitable kidney donors are available, as well as deploying PD programs and Home HD programs, will result in major overall cost savings. Our results provide a better understanding of the costs of kidney disease and will help to inform Ministry of Health and related policy makers as they develop short- and long-term strategies for the population, in terms of both cost savings and enhanced quality of life.

[Incidence of thrombophilia and risk of renal vessel thrombosis in kidney transplant recipients]

INTRODUCTION

Kidney transplantation is the optimal treatment of end stage kidney disease. The most common vascular complication in the early postoperative period is thrombosis of the renal artery and vein. These complications usually lead to the loss of the transplanted kidney.

AIM

of our study was to identify those factors which represent an increased risk for thrombotic complication and determine whether routine screening for thrombophilia is justifiable before transplantation. As an illustration to this problem we report a case of successful renal vein recanalisation after thrombosis.

METHODS

We give an overview of the literature about incidence of renal graft thrombosis, hypercoagulable states, predictive value of factor V. Leiden and prothrombin G20210A mutations in venous thromboembolism. We discuss those publications that suggest a preoperative screening of transplant candidates for hypercoagulable states and thrombophilia and those that do not think that such screening is reasonable. In our case a 28 year old male patient received a cadaveric kidney. Thrombosis of the renal vein was diagnosed 8 hours after transplantation. Reoperation was performed immediately: venous anastomosis was opened, the thrombus removed. After reoperation the circulation of the kidney recovered, intravenous heparin treatment was introduced immediately.

RESULTS

24 months later the kidney is still functioning well. Postoperative thrombophilia screening showed heterozygosity for factor V Leiden.

CONCLUSION

There are only few publications reporting on successful recanalisation after renal vein thrombosis. In our case rapid diagnosis and immediate operative treatment saved the graft. There is no uniform proposal in the literature whether preoperative screening for thrombophilia is justifiable or not. In our view screening for thrombophilia and thromboprophylaxis is mandatory. Extensive prospective studies should be undertaken to refine the risks and establish the associations of thrombophilia and thromboembolism after kidney transplantation.

Ego mechanisms of defense are associated with patients' preference of treatment modality independent of psychological distress in end-stage renal disease

Several parameters mediate the selection of treatment modality in end-stage renal disease (ESRD). The nephrology community suggests that patient preference should be the prime determinant of modality choice. We aimed to test whether ego mechanisms of defense are associated with patients' treatment modality preferences, independent of psychological distress. In 58 eligible ESRD patients who had themselves chosen their treatment modality, we administered the Symptom Distress Checklist-90-R and the Defense Style Questionnaire. Thirty-seven patients (53.4%) had chosen hemodialysis and 21 (46.6%) peritoneal dialysis. Patients who preferred peritoneal dialysis were younger (odds ratio [OR], 0.89; 95% confidence interval [CI]: 0.804-0.988), had received more education (OR, 8.84; 95% CI: 1.301-60.161), and were twice as likely to adopt an adaptive defense style as compared to patients who preferred hemodialysis (57.1% vs 27.0%, respectively; P < 0.033). On the contrary, the latter were more likely to adopt an image-distorting defense style (35.1% vs 14.3%; P = 0.038) and passive-aggressive defenses (OR, 0.73: 95% CI: 0.504-1.006). These results were independent of psychological distress. Our findings indicate that the patient's personality should be taken into account, if we are to better define which modalities are best suited to which patients. Also, physicians should bear in mind passive-aggressive behaviors that warrant attention and intervention in patients who preferred hemodialysis.

Modality options for renal replacement therapy: The integrated care concept revisited

As the End-stage renal disease population continues to grow, innovative strategies that optimize patient outcomes while capitalizing on the relative strengths of the existing modalities must be sought. Renal transplantation remains the preferred form of renal replacement therapy, but given the limited supply of donor organs, dialytic therapies will continue to constitute a large part of the modality mix. Matching patients to the most suitable modalities requires that a number of factors be considered. These include the patient's autonomy, medical and social factors, system-related issues, patient outcomes, and finances. While peritoneal dialysis and hemodialysis (HD) have traditionally been viewed as competing modalities, we propose that they, along with home and frequent HD regimens, may be used in a complementary manner, which is based on current evidence, and may provide optimal outcomes while containing treatment costs. In this review, we attempt to synthesize the current literature describing the various issues that affect modality selection, and offer an approach to achieving a balance between these many competing factors.

Comparative costing analysis of intensive care services between Hungary and United Kingdom

OBJECTIVE

The study presents the findings of the first National Intensive Care Cost Block Analysis in Hungary.

METHODS

There were 13 Intensive Care Units (ICUs) involved in this study: 5 University Hospitals, 6 District County Hospitals and 2 City Hospitals. The annual costs of ICUs were measured by "top-down" approach based on Cost Block Method. Annual expenditure of 3 cost blocks was collected for year 2000: clinical support, consumables and staff costs. On top of the annual costs, we collected general ICU data and Top 10 drugs of each unit. Our data was compared to National Cost Block data of United Kingdom.

RESULTS

There were 9313 patients involved in the study. The median (IQR) ICU occupancy rate was 67% (62-79), mortality was 21% (11-26). The mean cost per bed was 30,990 Euro (SD 12,573) and 144 Euro (SD 63,1) per patient day. Clinical support services were accounted for 9.6% of resources, consumables for 60.6% and staff costs for 29.8%.

CONCLUSIONS

Intensive care costs are very low in Hungary compared to other European countries. The difference is explained by the cheaper staff cost, but the lower number of nurses per ICU bed contributes as well.

An international registry to compare quotidian dialysis regimens with conventional thrice-weekly hemodialysis: why, how, and potential pitfalls

Thrice-weekly hemodialysis is the most commonly used form of renal replacement therapy, yet it is associated with unacceptably high morbidity and mortality. Attempts to improve outcomes for hemodialysis patients by increasing their per-session dose of dialysis have recently proven unsatisfactory in the multicentered Hemodialysis (HEMO) study. Interest has thus turned to increasing dialysis frequency. Short daily and long nocturnal dialysis, which are typically performed 6 days per week, are gaining acceptance and are associated with significant improvements in secondary outcomes, including nutrition, left ventricular hypertrophy, hypertension, anemia, and calcium-phosphorus balance. Studies to date have not been adequately powered to detect the survival benefits that these changes may confer. Large-scale randomized studies are planned, but will likely not answer the survival question for several years. Until this issue is resolved, funding policies are unlikely to change, confining current dialysis patients to potentially suboptimal therapy. By capturing data from current and future daily dialysis patients using an international registry, a survival benefit might be demonstrated more quickly. Such a project will soon be undertaken by the London Daily/Nocturnal Study Group with endorsement from the International Society for Hemodialysis and the U.S. National Institutes of Health. This database will also provide useful descriptive data that will help develop methodologies in this growing field. Historically the interpretation of dialysis registry data has been plagued with various methodological problems. These are briefly reviewed, and some potential solutions and necessary precautions are discussed.
