Abstract
BACKGROUND Intestinal transplantation (ITx) is the most expensive abdominal organ transplant. Detailed studies about exact costs and cost-effectiveness compared to home parenteral nutrition (HPN) therapy in chronic intestinal failure are lacking. The aim is to provide an in-depth analysis of ITx costs and evaluate cost-effectiveness compared to HPN. METHODS To calculate costs before and after ITx, costs were analyzed in 12 adult patients. To calculate the costs of patients with uncomplicated chronic intestinal failure, 28 adults, stable HPN patients were studied. Total costs including surgery, admissions, diagnostics, HPN therapy, medication, and ambulatory care were included. Median (range) costs are given. RESULTS Costs before ITx were €69 160 (€60 682-90 891) in year 2, and €104 146 (€83 854-186 412) in year 1. After ITx, costs were €172 133 (€122 483-351 407) in the 1st year, €40 619 (€3905-113 154) in the 2nd year, and dropped to €15 743 (€4408-138 906) in the 3rd year. In stable HPN patients, the costs were €83 402 (€35 364-169 146) in the 1st year, €70 945 (€31 955-117 913) in the 2nd year, and stabilized to €60 242 (€29 161-238 136) in the 3rd year. CONCLUSIONS ITx, although initially very expensive, is cost-effective compared to HPN in adults by year 4, and cost-saving by year 5.

Association Between the Placement of a Double-J Catheter and the Risk of Urinary Tract Infection in Renal Transplantation Recipients: A Retrospective Cohort Study of 1038 Patients. Transplant Proc 2021; 53:1927-1932. [PMID: 34229904 DOI: 10.1016/j.transproceed.2021.05.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Revised: 04/11/2021] [Accepted: 05/04/2021] [Indexed: 12/17/2022]
Abstract
BACKGROUND The incidence of urinary complications in transplantation is 2% to 20%, which can be decreased with the use of a double-J catheter. The objective of this study was to determine the association between the use of the catheter and the probability of urinary tract infection (UTI). METHODS We studied a retrospective cohort of 1038 patients divided into 2 groups: those treated with vs without a double-J catheter. Perioperative factors related to catheter use were analyzed. Second, whether the use of the catheter was associated with fewer other urinary complications was analyzed. RESULTS Of the whole sample, 72 patients were eliminated from the study, and 358 (37%) received a double-J catheter. UTIs occurred in 190 patients (19.6%), of whom a greater proportion received a catheter: 88 of 358 (24.6%) vs 102 of 608 (16.8%) (odds ratio, 1.61; 95% confidence interval, 1.17-2.22; P = .003). CONCLUSIONS The placement of a double-J catheter during transplant is associated with a higher proportion of UTIs, increasing their severity and the cost of care, without having a clear effect on other types of urinary complications.

Abstract
OBJECTIVES To investigate the cumulative return-to-work (RTW) rate and to identify predictors of employment after kidney transplantation (KT). DESIGN Retrospective, outpatient-based cohort study. SETTING This was a single-centre study of the largest Japanese kidney transplant centre. PARTICIPANTS We selected Japanese kidney transplant recipients aged 20-64 years who were employed in paid jobs at the time of transplantation and who visited an outpatient clinic from December 2017 to March 2018. From 797 patients, we evaluated 515 in this study. INTERVENTIONS We interviewed patients at an outpatient clinic and investigated the timing and predictors of RTW using logistic regression models. PRIMARY AND SECONDARY OUTCOME MEASURES The primary outcome was the cumulative RTW rate, and the secondary outcome was to investigate the predictors of RTW after KT. RESULTS Among the 515 included recipients, the cumulative overall partial/full RTW rates at 2, 4, 6 and 12 months were 22.3%, 59.0%, 77.1% and 85.0%, respectively. The median duration from transplantation to RTW was 4 months. Regarding partial/full RTW, according to the multivariable analysis including all variables, male sex was a greater predictor for RTW than female sex (OR 2.05, 95% CI 1.32 to 3.20), and a managerial position was a greater predictor than a non-managerial position (OR 2.23, 95% CI 1.42 to 3.52). Regarding full RTW, male sex (OR 1.95, 95% CI 1.25 to 3.06) and managerial position (OR 1.95, 95% CI 1.25 to 3.06) were also good predictors. CONCLUSIONS The cumulative RTW rate was 85.0% 1-year post-transplantation. Given that cumulative RTW rates varied by sex and position, transplant and occupational physicians should support kidney transplant recipients in the aspect of returning to work. TRIAL REGISTRATION NUMBER UMIN000033449.

Abstract
Background Health-Related Quality of Life (HRQoL) assessment after kidney transplantation has become an important tool in evaluating outcomes. This study aims to identify the associated factors with HRQoL among a representative sample size of Kidney Transplant Recipients (KTR) at the time of their inclusion in the study. Methods Data of this cross-sectional design is retrieved from a longitudinal study conducted in five French kidney transplant centers in 2011, and included KTR aged 18 years with a functioning graft for at least 1 year. Measures include demographic, psycho-social and clinical characteristics. To evaluate HRQoL, the Short Form-36 Health Survey (SF-36) and a HRQoL instrument for KTR (ReTransQol) were administered. Multivariate linear regression models were performed. Results A total of 1424 patients were included, with 61.4% males, and a mean age of 55.7 years (±13.1). Demographic and clinical characteristics were associated with low HRQoL scores for both questionnaires. New variables were found in our study: perceived poor social support and being treated by antidepressants were associated with low scores of Quality of Life (QoL), while internet access was associated with high QoL scores. Conclusion The originality of our study’s findings was that psycho-social variables, particularly KTR treated by antidepressants and having felt unmet needs for any social support, have a negative effect on their QoL. It may be useful to organize a psychological support specifically adapted for patients after kidney transplantation.

Abstract
Background— Kidney transplantation is generally acknowledged as the more clinically effective and more cost-effective option in managing patients with end-stage renal disease, compared with dialysis. This study looked for confirmatory evidence in a Hungarian population. Methods— Patients (n = 242) with end-stage renal disease who received cadaveric kidney transplantation during 1994 were followed up for 3 years. They were compared with patients (n = 840) receiving hemodialysis who were on a waiting list for transplantation. Data were collected retrospectively. Treatments were compared for clinical efficacy and for cost-effectiveness. Results— At month 36, the standard mortality hazard function was 3.5 times higher in the group receiving hemodialysis ( P<.0001) than in the transplant recipients. Average treatment costs per patient over the 3 years were also significantly higher ( P<.0001) in the hemodialysis group than in the group that received transplants. The cost of 1 year gained by transplantation was significantly less ( P<.0001) than the cost associated with hemodialysis. Conclusions— Compared with hemodialysis, kidney transplantation provides greater survival benefits to patients with end-stage renal disease, at less cost.

Abstract
Context Exploration of the role of critical care professionals in improving organ donation within Canada has been limited to tertiary care centers while donor potential in smaller nontransplant hospitals remains unknown. Objective To gain an understanding of the knowledge, attitudes, and perceived barriers that healthcare professionals in 5 nontransplant hospitals in Alberta have toward organ donation and transplantation, and to identify factors that influenced participation in the donation process. Design A descriptive survey of critical care professionals. Setting Five nontransplant hospitals in Alberta, Canada. Results Of the 135 respondents, 98 were critical care nurses, 32 were physicians, and 5 were hospital administrators. Respondents were least knowledgeable about transplant statistics and religious beliefs regarding donation, although overall, attitudes reflected positive support for organ donation. Respondents exhibited reluctance in approaching a potential donor family, and believed inadequate resources were allocated for organ donation. Conclusions Educational programs are needed to increase knowledge of organ donation and transplantation as well as the development of an in-house coordinator program in nontransplant hospitals for critical care personnel.

Abstract
Organ transplantation continues to be an excellent therapeutic option for patients with end-stage organ disease. Due to advances made in immunosuppression, surgical techniques, and critical care management, graft and patient survival rates continue to improve. Although advances in technology have dramatically changed in the field of organ transplantation over the last several decades and complicated ethical decision-making, the fundamental ethical principles of beneficence, nonmaleficence, autonomy, and justice have not. Organ transplantation still remains a problem of supply and demand and challenges transplant professionals to meet society's push to find new organ donor sources.

Abstract
INTRODUCTION Transplantation is the most effective treatment strategy for end-stage renal failure. We aimed to investigate the correlation of volume control parameters with health-related quality of life (HRQoL) in renal transplantation patients during the pre- and post-transplantation periods. MATERIAL AND METHODS Seventy-seven patients who underwent renal transplantation from deceased donors between January 2011 and January 2013 were included in the study. The biochemical markers, complete blood count, and creatinine levels were measured during pretransplantation and at post-transplantation month 6. The Turkish version of the Short Form 36 (SF-36) health survey questionnaire was used for the assessment of HRQoL. Blood pressure (BP) and echocardiographic measurements were used to evaluate the volume status. RESULTS Significant improvements were achieved in all echocardiographic measurements, biochemical parameters except Ca(++), and SF-36 questionnaire domain scores (DSs) except vitality in the post-transplantation period. Systolic BP (SBP), the left atrium index, vena cava inferior collapsibility index (VCCI), and diastolic BP were associated with vitality (P = .02, .03, .05, and .04, respectively); SBP was associated with social functioning (P < .01) and role emotional (P < .01); and left ventricular mass index was associated with mental health (P = .05) DSs during the pretransplantation period. In the post-transplantation period, VCCI, left ventricular mass index, and SBP were associated with general health (P = .02, .05, and .05, respectively); VCCI and SBP were also associated with mental health (P = .05 and .01, respectively); and left atrium index was associated with role emotional (P = .05) DSs. CONCLUSION Concomitant improvement in the volemic status may contribute to improvements in HRQoL after renal transplantation.

Abstract
Acute rejection (AR) includes T-cell-mediated and antibody-mediated rejection. The inflammatory infiltrate comprised not only T cells but also varying amounts of B cells (CD20(+)) and plasma cells (CD138(+)). The latter are associated with poor clinical outcomes, but their functional status is not clear. The phosphorylation of the S6 ribosomal protein (p-S6RP) is present in cells that are metabolically active, thus identifying functionally active antibody-secreting plasma cells. This study was designed to evaluate the clinical significance of functionally active p-S6RP plasma cells in AR in renal allografts. Renal allografts with biopsy evidence of AR during 2006-2009 were included. Immunohistochemistry staining for CD20, CD138, and p-S6RP was performed on paraffin-embedded slides and scaled as 0-6. The response to antirejection treatment was assessed by the serum creatinine ratio (CrR) at rejection episode (time 0) and following treatment (4 and 12 weeks). Patients with lower scores (0-2) were compared with a higher scored group (3-6). The T-test was conducted using statistical significance of p<0.05. A total of 28 patients (40.7 ± 14.3 year; M:F=15:13) were diagnosed with acute T-cell-mediated rejection (I and II). The p-S6RP staining in the high-score group had a significantly higher CrR (p<0.05) than the low-score group at the time of biopsy, 4 and 12 weeks following treatment. There was no significant difference in the CrR between groups for CD20 or CD138 staining. Functional antibody-secreting p-S6RP plasma cells are actively participating in AR and associated with poor response to treatment in renal allografts.

Abstract
OBJECTIVE This study evaluated the outcomes of laparoscopic donor nephrectomy (LDN) and proposed modifications for kidney donation surgery. From February 1997 to February 2011, 1510 LDNs were performed. PATIENTS AND METHODS Surgical modifications included a modified open access technique for entry into the abdominal cavity, using vascular clips for safe and cost-effective control of the renal pedicle, control of the lumbar veins, and adrenal vein using bipolar cautery instead of clips, and leaving the gonadal vein intact with the ureter. Kidneys were extracted by hand through a Pfannenstiel incision. Heparin was not used after the first 300 cases to prevent potential hemorrhagic complications. RESULTS Although three major vascular injuries occurred using the closed access method that were managed successfully, no access-related complications occurred using the modified open access technique. Clip failure did not happen in any cases. Patient and graft survival at 1 year post-transplantation were 96.5% and 95.5%, respectively, and at 5 years post-transplantation were 95.3% and 89.5%, respectively. CONCLUSION The proposed surgical modifications are based on 14 years of experience and 1510 cases, and make LDN simple, safe, and cost-effective. The excellent recipient and graft outcomes with minimal morbidity obtained further confirm that LDN can be considered as the gold standard for kidney donation surgery.

Abstract
Context The increasing number of marginal deceased kidney donors and an aging recipient population, prolonged hospitalization, and increased costs have destabilized the economic viability of kidney transplants. Objective To determine if a delay in the administration of the day-of-discharge dose of rabbit antithymocyte globulin would result in equivalent clinical outcomes with cost savings. Design Single-center, prospective, observational before-and-after study of adult kidney transplant recipients who received induction with rabbit antithymocyte globulin. Intervention—Patients who received a transplant between June 2006 and February 2009 and received rabbit antithymocyte globulin served as the control group. Patients who received a transplant between March 2009 and August 2010 and received rabbit antithymocyte globulin had the day-of-discharge dose delayed to the following day and administered in the clinic. A total of 231 patients (146 in the control group, 85 in the study group) were included. Baseline demographic and clinical characteristics were similar in the 2 groups. Results Patients who had delayed administration of rabbit antithymocyte globulin had shorter stays (3.9 vs 3.1 days, P .001) and reduced inpatient costs for rabbit antithymocyte globulin (mean $860/patient); these changes were achieved without affecting acute rejection rates (5% vs 5%, P>> .99) or readmission rates. In conclusion, delayed inpatient administration of rabbit antithymocyte globulin provided identical clinical outcomes while helping to reduce inpatient costs and increase timely discharges.

Abstract
OBJECTIVES To evaluate and compare the long-term graft and survival rates in kidney transplant recipients who had undergone laparoscopic donor nephrectomy versus those who underwent open donor nephrectomy. MATERIALS AND METHODS Our study was done with 100 cases of laparoscopic donor nephrectomy and 100 cases of open donor nephrectomy, performed between July 2001 and September 2003. Mean follow-up of recipients in this study was 6.6 ± 2.4 years (range, 1-9.3 y). This study has a longer follow-up than previous randomized clinical trials. We compared patient and graft survival in recipients of laparoscopic donor nephrectomy versus those who had open donor nephrectomy. RESULTS Mean duration of kidney warm ischemia time was 8.7 ± 2.7 minutes for laparoscopic donor nephrectomy and 1.8 ± 0.92 minutes for open donor nephrectomy. There were no significant differences in 5-year graft survival between the laparoscopic donor nephrectomy and open donor nephrectomy groups (89.5% vs 84.3%; P = .96). There were no differences in delayed graft function between the laparoscopic donor nephrectomy and open donor nephrectomy groups (8 and 11 patients; P = .135). There was a significant difference in 5-year graft survival between recipients with a history of delayed graft function and those without delayed graft function (63.2% vs 89.7%; P = .04). Despite a longer warm ischemia time in laparoscopic donor nephrectomy group (8.69 vs 1.87 min; P = .0001), warm ischemia time had no effect on graft outcome in long-term follow-up. CONCLUSIONS Although earlier experiences with laparoscopic donor nephrectomies were associated with concerns about long-term effects of laparoscopic donation on the graft function in the recipient, our long-term results confirm that laparoscopic donor nephrectomy provides similar graft outcome to open donor nephrectomy.

Abstract
Acute rejection in renal transplant recipients is diagnosed by renal biopsy at an advanced disease stage. There is no modality for sequential monitoring of graft status. We studied the role of urine cytology in predicting acute cellular rejection (ACR) and its ability to correctly diagnose ACR and differentiate it from drug toxicity (DT). Urine samples from 203 renal transplant recipients were studied to determine the cellular composition using cytology and immunocytochemistry for HLA-DR, intercellular adhesion molecule (ICAM)-1, and interleukin (IL)-2R. In a 3-month follow-up period, there were 36 episodes of graft dysfunction, of which 28 occurred due to ACR and 8 due to DT. The cytology results showed a significantly increased percentage of lymphocytes and polymorphonuclear cells in samples obtained before and during the clinical manifestations of ACR. A greater level of expression of antigens was observed before and during ACR. The use of IL2-R-, ICAM-1-, and HLA class II-specific monoclonal antibodies gave very high specificity, sensitivity, and positive predictive values in diagnosing rejection through urine cytology, suggesting that routine cytology along with immunocytochemistry of urine sediment has clinical potential for early diagnosis and management of ACR and DT.

Abstract
BACKGROUND AND OBJECTIVES Immunosuppressive medications are essential in preventing kidney transplant rejection. Continuous insurance coverage for outpatient immunosuppressive medications remains a major issue. The objective of this study was to establish the prevalence and consequences of cost-related immunosuppressive medication nonadherence. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS A descriptive survey of all U.S. kidney transplant programs (n = 254) was conducted. The response rate for the survey exceeded 99%. The main outcome measures included the following: transplant recipient concerns related to medication costs, ability to pay for medications, medication nonadherence and its consequences, and failure of transplant centers to place patients on the transplant waiting list. RESULTS Continuous insurance coverage for outpatient immunosuppressive drugs is a problem having potentially grave consequences for the majority of kidney transplant recipients. More than 70% of kidney transplant programs report that their patients have an extremely or very serious problem paying for their medications. About 47% of the programs indicate that more than 40% of their patients are having difficulty paying for their immunosuppressive medications. In turn, 68% of the programs report deaths and graft losses attributable to cost-related immunosuppressive medication nonadherence. Some of the problems identified here are more significant for adult than pediatric patients. CONCLUSIONS The prevalence and consequences of cost-related immunosuppressive medication nonadherence among kidney transplant recipients have now been documented. The results presented here should serve as the necessary impetus for the development of health care policies supporting Medicare coverage of immunosuppressive medications for the life of the transplanted kidney.

Abstract
This study investigates the influence of various altruistic, cognitive, and attitudinal factors on the organ donation intention in Egypt. Using a large sample, a conceptual model has been developed. The findings from the structural equation model confirm the influence of the respondents' altruistic values, perceived benefits and risks, and knowledge on their attitudes towards organ donation. Respondents' attitudes towards organ donation, in turn, are also found to affect their organ donation intention. One of the other important findings suggests that on a declarative level, more and more individuals in Egypt express their concern over the shortage of available organs and declare their willingness to contribute somehow to alleviate the problem. However, in reality this concern may not be manifested consistently.

Abstract
Unrelated kidney transplants have lead to commerce and kidney vending in Pakistan. This study on 104 vendors reports demographics, history, physical and systemic examination, ultrasound findings, renal and liver function and GFR by Cockcroft-Gault. Results were compared with 184 age, sex and nephrectomy duration matched living-related donors controls. Comparison of vendors versus controls showed mean age of 30.55 +/- 8.1 versus 30.65 +/- 7.85 (p = 0.91) years, M:F of 4.5:1 versus 4.2:1 and nephrectomy period of 33.89 +/- 30 versus 32.01 +/- 29.71 (p = 0.60) months respectively. Of the vendors 67% were bonded laborers earning <50 $/month as compared to controls where 68% were skilled laborers and self-employed earning >100 $/month. History of vendors revealed jaundice in 8%, stone disease in 2% and urinary tract symptoms in 4.8%. Postnephrectomy findings between vendors versus donors showed BMI of 21.02 +/- 2.8 versus 23.02 +/- 4.2 (p = 0.0001), hypertension in 17% versus 9.2% (p = 0.04), serum creatinine (mg/dL) of 1.17+/-0.21 versus 1.02 +/- 0.27 (p = 0.0001), GFR (mL/min) of 70.94 +/- 14.2 versus 95.4 +/- 20.44 (p = 0.0001), urine protein/creatinine of 0.150 +/- 0.109 versus 0.10 +/- 0.10 (p = 0.0001), hepatitis C positivity in 27% versus 1.0% (p = 0.0001) and hepatitis B positive 5.7% versus 0.5% (p = 0.04), respectively. In conclusion, vendors had compromised renal function suggesting inferior selection and high risk for developing chronic kidney disease in long term.

Abstract
OBJECTIVE The non-heart-beating donor has been proposed as a solution to donor shortage for renal transplantation. Because the nature of such donors, the kidneys so derived have been damaged by primary warm ischemia (WI), and so potentially they may never function. Minimizing graft injury is especially important in case of transplantation form marginal donors because of a high rate of delayed graft function or primary nonfunction. The aim of this experimental study is to assess the structural and hemodynamic consequences of hypothermic perfusion (HP) versus cold storage (CS), in renal allograft after a period of WI. MATERIAL AND METHODS We used 20 mini-pigs. WI was achieved by vascular pedicle occlusion during 45 min. We divided organs in 4 groups: A (n=5), kidneys with WI and then transplanted; group B (n=5), grafts with WI and implanted after HP with Belzer solution in our computerized perfusion system. Group C-control, (n=5) transplanted without WI and D (n=5) with WI and 60 min of CS in UW-Viaspan solution. All the procedure was recorded by a computerized data system. Renal vascular resistance (RVR) and renal vascular flow (RVF) were automatically calculated by means of mathematical formulas after renal transplantation. Subsequently histological study was completed in all cases. RESULTS We observed two patterns after transplantation: (1). Initial increase of RVR with posterior decrease and increase of vascular flow: in organs with WI and HP prior to transplantation (group B) // organs transplanted without WI (group C-control). Electronic and conventional microscopy showed integrity of endothelial and tubule structure. (2). Initial decrease with posterior increase of RVR. Organs with WI (group A) // organs with WI and CS (group D). Structural study showed endothelial and tubule disruption. CONCLUSION In our experimental model machine perfusion preserves endothelial and tubule structure of kidneys with WI. After transplantation the hemodynamic pattern of grafts with WI and HP is similar to the control group (without WI and direct transplantation).

Abstract
INTRODUCTION Kidney transplantation is currently the treatment of choice for end-stage renal disease. As the successful transplantation improves the physical and mental quality of life, it is expected that the transplant recipient should play a productive role in the society. The present study evaluates the occurrence and predictors of employment after kidney transplantation. METHODS Population-based cross-sectional study in which 272 adult kidney recipients assisted in a Brazilian Southern state were evaluated. RESULTS At the moment of the interview, 29% of the patients were employed. After analysis with logistic regression, the predictors of employment were male sex (OR 4.04; 95% CI 1.99-8.23), pre-transplant employment for non-diabetic (OR 4.35; 95% CI 3.79-4.99), diabetes for individuals who worked while on dialysis (OR 0.06; 95% CI 0.008-0.5), high educational level for individuals with mental quality of life scores above the 25th percentile (OR 3.06; 95% CI 2.98-3.14 for 50th percentile of mental quality of life). The Hosmer-Lemeshow test was of 3.33 (p = 0.91). CONCLUSION The participation of the kidney transplant recipients with functioning graft into the work force in the Brazilian state of Rio Grande do Sul is low, being predicted mainly by sociodemographic factors. It was not detected any influence of patient perception of his/her physical conditions or other clinical variables, except for the presence of diabetes.

Abstract
BACKGROUND Blacks are disproportionately affected by chronic kidney disease, but are far less likely to undergo live donor kidney transplantation (LDKT) than whites. We assessed the differential effectiveness in blacks and whites of a home-based (HB) LDKT educational approach. STUDY DESIGN A planned secondary analysis of a previously published randomized trial. SETTING & PARTICIPANTS 132 patients (60 black, 72 white) approved for kidney transplantation at 1 kidney transplant center in the southeastern United States. INTERVENTION Assignment to receive either standard clinic-based (CB) transplant education (n = 69) or CB plus an HB (CB + HB) LDKT education program (n = 63). The HB education program was culturally sensitive for blacks, including using a minority health educator, brochures that highlight minority transplant recipients and donors, and discussion of race-specific outcome data. OUTCOMES Primary outcomes were proportions of patients with live donor inquiries, evaluations, and transplants 1 year after study participation. MEASUREMENTS Medical record and questionnaire data. RESULTS 69 patients were assigned to the CB group, and 63 to the CB + HB group. After 1 year, there were 96 living donor inquiries (72.7%), 62 living donor evaluations (47.0%), and 54 LDKTs (40.9%). Patients assigned to the CB + HB group were more likely to have had living donor inquiries (odds ratio [OR], 1.7; confidence interval [CI], 1.2 to 3.0), a living donor evaluated (OR, 2.7; CI, 1.4 to 5.4), and LDKT (OR, 3.0; CI, 1.5 to 5.9). The effect was greater in blacks than whites for living donor evaluations and LDKT, but not for living donor inquiries (treatment-by-race interaction, P < 0.001, P < 0.001, and P = 0.8, respectively). Blacks in the CB + HB group were more likely to have had at least 1 living donor inquiry (51.7% versus 77.4%), at least 1 living donor evaluated (17.2% versus 48.4%), and LDKT (13.8% versus 45.2%) than those in the CB group. By comparison, whites in the CB + HB group were more likely to have had at least 1 living donor inquiry (72.5% versus 87.5%), at least 1 living donor evaluated (47.5% versus 71.9%), and LDKT (42.5% versus 59.4%) than those in the CB group. LIMITATIONS Single-center study with greater dropout rate in the CB + HB group. CONCLUSIONS These results suggest that a culturally sensitive LDKT education program that reaches out to blacks and their social support network can overcome some barriers to LDKT in this population.

Abstract
Background Living donor kidney transplantation has several advantages for patients with end-stage renal disease. However, many patients are reluctant to pursue this treatment option, preferring instead to wait for a deceased donor organ. Objective To examine predictors of patients' willingness to talk to others about living kidney donation. Methods One hundred thirty-two adult patients awaiting kidney transplantation who were enrolled in a randomized trial examining the effectiveness of education on rates of live donor kidney transplantation completed a baseline rating of their willingness to talk to others about living kidney donation. Also, patients completed measures of knowledge and concerns about living donation and a rating of perceived health. Results Slightly more than half the patients (56.1%) had low willingness to talk to others about living donation. The following variables were associated with higher willingness to talk to others: white race (odds ratio, 3.31; confidence interval, 1.7–7.4), college education (odds ratio, 3.43, confidence interval, 2.0–5.6), fewer concerns about living donor kidney transplantation (odds ratio, 0.31; confidence interval, 0.2–0.6), and less favorable perceptions of their current health status (odds ratio, 4.31; confidence interval, 2.6–7.6). Conclusion White race, more education, less concern about living donor kidney transplantation, and poorer perceived health are associated with greater willingness to talk to others about living kidney donation. These findings have important implications for educating patients about living donor kidney transplantation.

Abstract
BACKGROUND Policies governing the allocation of deceased donor organs to nonresident aliens (NRAs) have existed from the early days of transplantation. However, there is a paucity of research describing this population. The aim of the present study is to examine characteristics and allocation patterns for NRAs compared to U.S. citizens in the context of the two most common forms of solid organ transplantation. METHODS The study included kidney and liver transplant candidates and deceased donor transplant recipients from 1988-2005 in the United States. We describe demographic characteristics, insurance coverage, geographic variability, and donor relationship based on citizenship and residency status. We additionally examined the association of citizenship with time to transplantation utilizing survival models. RESULTS From 1988-2005, there were 2724 solitary kidney and 2072 liver NRA candidate listings with United Network for Organ Sharing. NRA recipients had more self-pay (liver 36% and kidney 22%) and foreign sources (liver 26% and kidney 13%) of insurance coverage. Transplants to NRAs were more frequent than deceased donations deriving from NRAs for both organs. Adjusted models indicated that NRA kidney candidates received transplants at the same rate as U.S. citizens while liver NRA candidates received transplants more rapidly during the pre-Model for End-Stage Liver Disease (MELD; adjusted hazard ratio [AHR] 1.2, confidence interval [CI] 1.2-1.3) and post-MELD (AHR 1.5, CI 1.3-1.7) eras. CONCLUSIONS NRAs are demographically and socioeconomically diverse and have historically had a more rapid progression on the waiting list to receive a liver transplant. Further discussion and investigation concerning the ethical, economic, and public health ramifications of transplantation to NRA patients are warranted.

Abstract
INTRODUCTION Although there are reports that link diabetes-induced end-stage renal disease (ESRD) with several post renal transplantation complications and conditions, few studies have directly focused on this issue. This study compared the pattern of rehospitalizations after renal transplantation among diabetic versus nondiabetic ESRD patients, measuring causes, length of stay, outcomes and costs. METHODS We retrospectively reviewed 366 randomly selected rehospitalization records of kidney transplant recipients between 1994 and 2006, including 69 who underwent renal transplantation due to diabetic nephropathy and 297, due to nondiabetic ESRD. We compared the two groups with respect to demographic and clinical variables: donor source, readmission pattern, rehospitalization cause, time interval between transplantation and hospitalization (T-H time), length of hospital stay (LOS), and intensive care unit (ICU) admission, hospital charges, and inpatient outcomes of graft loss and mortality. RESULTS The diabetes group, compared with nondiabetic group, had a greater mean age (53 +/- SD vs. 39 +/- SD years), proportion of admissions due to infections (44.9% vs. 32%) or renal dysfunction (14.5% vs. 29.6%), mean hospital charges ($5056 vs. $3046), and hospital mortality (18% vs. 4.3%; P<.05). Diabetic patients were readmitted sooner after transplantation than nondiabetic patients (11 vs. 18 months; P<.05). There was no difference between the groups with regard to gender, donor source, LOS, ICU admission, and graft loss. CONCLUSION The etiology of ESRD should be considered for scheduling post renal transplantation follow-up. Renal transplant recipients with diabetes-induced ESRD need further attention in follow-up programs.

PATIENTS AND METHODS In this retrospective study, 574 randomly selected rehospitalization records of kidney transplant recipients were reviewed from 1994 to 2006. Admissions were divided into group 1, prolonged stay (length of stay >14 days, n=149), and group II, short stay (length of stay <or=14 days, n=425). Demographic data, cause of end-stage renal disease (ESRD), cause of readmission, ICU admission, time interval between transplantation and rehospitalization, costs, and in-patient mortality were compared between the two groups. RESULTS Mean (+/-SD) hospital stay was 10.6 +/- 9.8 days. Median hospital stay was 5 days for renal stones, 7 days for surgical complications, 8 days for malignancy, 9 days for infection, and 10 days for renal dysfunction. We found higher rates of ESRD due to diabetes in group I (28% vs. 15.4%; P=.006). Admissions due to infections (56.4% vs 42.4%; P=.003) or renal dysfunctions (55% vs 41.4%; P=.004) were the cause of higher proportions of total hospitalizations with prolonged stay. Prolonged stay also correlated with higher ICU admissions (8.8% vs 2.8%; P=.002) and mortality (6.7% vs 3.05%; P=.001). Mean total hospital cost for short versus prolonged hospitalizations were US$ 586 versus US$ 2750, respectively. CONCLUSION In this study, we found that prolonged hospital stays accounted for >62% of all hospital costs; however, they comprised only 26% of the patients. High-risk kidney transplant recipients for prolonged hospitalizations should be closely observed for infections and graft rejection.

Abstract
BACKGROUND AND AIM This study sought to assess posttransplantation hospitalizations costs in diabetic and nondiabetic subjects to see whether diabetes mellitus (DM) as a primary cause of end-stage renal disease (ESRD) increased posttransplantation hospitalization costs. METHODS From 2000 to 2005, the hospitalization costs of 387 consecutive rehospitalizations of kidney recipients were retrospectively compared for two groups: patients with ESRD due to DM (n=71) and those with ESRD of non-DM etiologies (n=316). The hospitalization costs included the costs of hotel, medications, surgical procedures, paraclinical tests, imaging tests, health personnel time, special services (ie, patient transportation by ambulance), and miscellaneous costs. Societal perspective was used with costs expressed in PPP$ purchase power parity dollars (PPP$) estimated to be equal to 272 Iranian rials. RESULTS Compared with the non-DM group, DM patients experienced significantly higher median costs both in total (1262 vs 870 PPP$, P=.001) and in cost components related to hotel (384 vs 215 PPP$, P=.001), health personnel time (235 vs 115 PPP$, P<.001), paraclinical tests (177 vs 149 PPP$, P=.012), and special services (100 vs 74 PPP$, P=.041). The mean of age was higher (P<.001), and the transplantation hospitalization time interval was also shorter in the DM group (median: 2.7 vs 12, P=.025). CONCLUSIONS Considering DM as a leading cause of ESRD and its increasing prevalence in some countries, the association between hospitalization costs of posttransplant patients and DM may be of great economic importance to many transplantation centers.

Abstract
INTRODUCTION We sought to account for changes in posttransplant hospitalization patterns in terms of the changes in demographic and transplantation-related variables. METHODS AND MATERIALS We retrospectively analyzed 1860 cases of kidney transplantation performed between 1992 and 2004 in terms of demographic and transplantation-related variables. Of the 1860 cases, rehospitalization records in the first year posttransplantation were available for 1152 cases, which were assessed for causes of admission, mortality, graft loss, length of stay, and hospital charges. RESULTS The pattern of rehospitalizations showed the following trends: (1) Increased rate of infection; (2) Decreased rate of graft rejection; and (3) Peak costs of rehospitalization between 1999 and 2000. CONCLUSION We believed that the increased infection rate and decreased rejection rate may have been related at least partly to the shift in the treatment protocol from azathioprine-based to mycophenolate mofetil regimens in 2000. Furthermore, the peak in the relative frequency of diabetes mellitus and hypertension as the etiology of end-stage renal disease among those having undergone transplantation between 1999 and 2000 may have been responsible for the peak in rehospitalization costs and length of hospital stay. We are strongly of the opinion that hospital statistics are a valuable tool for health care policymakers to monitor transplantation outcomes.

Abstract
OBJECTIVE To summarize and assess literature regarding social participation of recipients after successful kidney transplantation. METHODS A systematic review including a literature search in Medline (1980-2003) and five other databases, and assessment of methodological quality of selected studies by two reviewers applying a checklist of twelve criteria. RESULTS Seventeen studies out of 1443 identified references were selected. Quality scores for internal validity ranged from 0% to 50% (median 20%). Employment was the most used indicator of social participation and two studies briefly reported on vacation and recreation. Employment rate ranged from 18% to 82%, however differences in defining categories of employment or lack of description were present. Study populations were heterogeneous with regard to demographic and clinical characteristics. Three studies identified pre-transplant employment status as predictor of post-transplant employment. Other potential risk factors were not consistent across studies. CONCLUSION Measurement of social participation focuses mainly on employment status. Quality assessment revealed shortcomings in reporting and validity of studies, whereby valid conclusions regarding the degree of social participation after kidney transplantation cannot be drawn. Future research should supplement the focus on employment status by examining other aspects of social participation as well as potential risk factors.

Abstract
PURPOSE To compare the long-term results of kidney transplantation from living unrelated donors (LURDs) with that from living related donors (LRDs). MATERIALS AND METHODS From 1984 to 2004, we performed 2155 kidney transplantations of which 374 were from LRDs and 1760 from LURDs. We reviewed and compared the long-term data from these cases. RESULTS The LURD group included 64.2% men with an overall mean age of 33.46 +/- 14.61 (range 3 to 76) years. Laparoscopic donor nephrectomy was performed in 329 cases (18.7%) with mean follow-up of 45.68 +/- 46.80 months. The LRD group included 66.5% of male recipients with overall mean age of 28.97 +/- 9.58 (range 9 to 65) years. Laparoscopic donor nephrectomy was performed in 12 cases (3.2%) of LRDs with mean follow-up of 81.15 +/- 67.03 months. One-, 3-, 5-, 10-, and 15-year graft survivals among LRDs were 91.6%, 81.7%, 76.4%, 64.4%, and 48.4%; and for LURDs, 91.5%, 86.7%, 81.4%, 68.2%, and 53.2%, respectively (P = .07). Patient survivals for 1, 3, 5, 10, and 15 years in LRDs were 94.6%, 91.9%, 83%, 79.5%, and 73.9%, and in LURDs were 93.6%, 91.7%, 89.3%, 84%, and 76.4%, respectively (P = .14). CONCLUSION The results of living unrelated kidney transplantation upon long-term follow-up with a large number of cases were as good as living related kidney transplantation. The organ shortage can be alleviated by using living unrelated kidney transplantation. To our knowledge this is the largest experience with long-term follow-up reported from one center to date.

Abstract
PURPOSE Despite the popularity of hand assisted laparoscopic donor nephrectomy published experience is less than that with standard laparoscopic donor nephrectomy and few critical assessments of operative maneuvers have been described. MATERIALS AND METHODS We describe the impact of changes in operative technique made by a single surgeon during 200 hand assisted laparoscopic donor nephrectomies. RESULTS With a mean operative time of 229 minutes and hospital stay of 1.9 days the rates of conversion to open surgery, intraoperative complications and major postoperative complications were 1%, 1.5% and 6%, respectively. Lasting changes in technique were dissection of a ureteral/gonadal packet, bipolar cautery use on gonadal/adrenal/lumbar veins and resting the kidney before removal. The incidence of ureteral complications decreased from 8% to 5.1% with dissection of the ureter in conjunction with the gonadal vein rather than isolating it. Warm ischemia time decreased from a mean of 186 to 143 seconds with bipolar electrocautery instead of clips to control gonadal/adrenal/lumbar veins. After starting to rest the kidney before removal the incidence of primary graft nonfunction and delayed function decreased from 6.7% to 0% and 30% to 11.8%, respectively, with a corresponding improvement in 2-year graft survival from 83% to 95%. CONCLUSIONS This large series of hand assisted donor laparoscopic nephrectomies with a mean followup approaching 3 years demonstrates that the procedure is safe for the donor and procures a good specimen. Decreases in ureteral complications, warm ischemia time and graft dysfunction might be attributable to specific changes in our operative technique.

Abstract
Preservation techniques are crucial to deceased donor kidney transplantation (DDTx), but the efficacy of pulsatile perfusion (PP) versus cold storage (CS) remains uncertain. We describe patterns of PP use and explore four fundamental questions. What kidneys are selected for PP? How does PP affect utilization of donated kidneys? What effect does PP have on outcomes? When does PP appear to be most efficacious? We examined rates of PP in DDTx in the United States from 1994 to 2003. We generated models for organ utilization, delayed graft function (DGF) and for the use of PP. We analyzed the long-term effect of PP with multivariate Cox models. The utilization rates for non-expanded criteria donors (ECDs) were similar by storage type, but for ECDs there was a significantly higher utilization rate with PP (70% with PP vs. 59% with CS, p < 0.001). Use of PP was widely variable across transplant centers. DGF rates were significantly lower with PP (27.6% vs. 19.6%). PP was associated with a mild benefit on death censored graft survival (adjusted hazard ratio = 0.88, 95% CI 0.85-0.91). Reduced DGF and significantly lower discard rates of ECDs associated with PP suggest an important utility of PP in renal transplantation. Additional evidence of improvement in graft survival, particularly in more recent years, provides further encouraging evidence for the use of PP.

Abstract
PURPOSE Living, genetically unrelated donor renal transplantation (LURT) is being performed with increasing frequency. We evaluated our single center experience with LURT and compared this to a cohort of living related donor renal transplants (LRT) to evaluate the short-term success of LURT at our center. MATERIALS AND METHODS We identified 99 consecutive patients who underwent LURT at our center and had at least 1 year of followup data. A control cohort of 99 patients who underwent LRT at our center matched for age, number of transplants and date of transplant was also identified. One-year graft and patient survival, and serum creatinine levels at 1, 3, 6 and 12 months were compared between the groups. Our data were compared with national and international data. RESULTS At our center 1-year graft survival was 95% in the LURT and LRT cohorts. One-year LURT patient survival was 99% compared with 97% in the LRT group and the serum creatinine levels were not significantly different. CONCLUSIONS Patients undergoing LURT at our center have excellent 1-year graft and patient survival compared with LRT performed at our center, and national and international LURT. Genetically unrelated kidney donors should continue to be used to expand the kidney donor pool.

Abstract
BACKGROUND Despite increasing numbers of patients receiving hemodialysis in satellite units (SHD), the economic aspects have not been widely explored. A cost analysis of SHD and in-center hemodialysis (ICHD) from a societal perspective was performed to establish the efficiencies associated with shifting resources and patients from ICHD to SHD. METHODS Costs were classified as fixed or variable and placed into categories. The resources for operating a SHD unit are the sum of two components: total fixed costs (TFC) and average variable cost (AVC) times SHD patient volume (Q). Using the TFC of a specific-sized SHD unit and the difference in AVC between ICHD and SHD the number of patients needed (Q) in the SHD unit for financial viability was determined. The formula TFC = (AVC(ICHD) - AVC(SHD)) X Q was used to determine the number of patients (Q) needed in a specific-sized SHD unit such that the yearly cost of SHD treatment would be the same as ICHD treatment. RESULTS Our results show that SHD fixed costs can be fully offset if the volume of SHD patients is seven per year in a six-station unit. SHD costs were lower for nursing and physician fees. Therefore, ICHD care variable costs were $11,374 more per patient year. SHD patients would also have lower travel costs, a mean cost saving of $12,364 per year. CONCLUSION SHD can result in significant savings both to the health-care system and to patients. Using the cost categories and formula presented, the number of patients needed in a specific-sized satellite unit to realize cost savings was determined for our program. We found that these savings can offset the fixed investment needed to operate a SHD unit at modest patient volumes.

Abstract
Organ transplantations are among the most expensive surgical treatments performed today, but estimates of the costs of organ transplantations vary widely between settings. The aim of this study is to estimate the costs of renal, liver and heart transplantation in a university hospital, adopting a similar costing methodology for all the three kinds of transplantation. Resource use data were collected from 803 patients transplanted between January 1995 and August 2001. Data about the time physicians and other hospital employees spent per transplantation were based on interviews. All costs from pretransplantation screening up to 3 years post-transplantation were taken into account and divided into costs of patient care and programme-related costs. Mean cost of renal transplantation varied from 70,723 Euros for cadaveric donor transplantations to 76,577 Euros for living donor transplantations. Mean costs of liver transplantation were 141,510 Euros and the mean costs of heart transplantation were 17, 828 Euros. Direct costs of patient care contributed to 79%, 87% and 92% of the costs of renal, liver and heart transplantation respectively. Inpatient hospital days were the largest contributor to the costs of patient care. The mean number of inpatient hospital days from pretransplantation screening to 3 years post-transplantation varied from 46 days for renal transplantation from a living donor to 58 days for renal transplantation from cadaveric donors, 83 days for heart transplantation and 108 days for liver transplantation. In conclusion, costs of liver and heart transplantation were approximately 2.0 and 2.5 times higher than the cost of renal transplantation. Length of inpatient hospital stay for transplantation did not change substantially over time between 1995 and 2001.

Abstract
Kidney transplantation is a superior treatment strategy than chronic dialysis for end-stage renal disease patients. However, there is a severe shortage of cadaveric kidneys that are available for transplantation. Therefore many patients are turning to living donors. We describe four models of incentives to improve rates of living kidney donation: the market compensation model, the fixed compensation model, no-compensation model and the expense reimbursement model. We discuss the advantages and disadvantages of each of these models. Any incentive to improve rates of living kidney donation must be accompanied by safeguards. These safeguards will prevent living donors from being viewed primarily as a resource for transplants. These safeguards will also prevent vulnerable individuals from being coerced into donation and will monitor long-term outcomes of donors using a donor registry. We recommend the use of the expense reimbursement model along with these safeguards, in order to increase rates of living kidney donation.

Abstract
BACKGROUND The purpose was to demonstrate the cost-effectiveness of an experimental post-transplant care program designed to improve kidney transplant recipients' quality of life (QoL). The intervention program integrated a three-pronged interdisciplinary approach emphasizing: (i) proactive, patient-initiated care to prevent transplant-related morbidities, (ii) employment/vocational counseling, and (iii) enhancement of social support. METHODS A cost-effectiveness analysis of a clinical trial was performed comparing QoL and costs in two groups: a retrospective cohort (n = 30) and those who received the experimental interventions (n = 150). Data were collected at baseline, 6 and 12 months. The number of quality-adjusted 'treatment-free days' was used as the primary outcome. The costs included those for direct intervention, direct inpatient and outpatient post-transplant health care, and indirect out-of-pocket expenses borne by patients. RESULTS Patients in the intervention group had more quality-adjusted treatment-free days (289 vs. 272 and statistically significant) and lower cost per patient (although not statistically significant). Further, the superior outcome was delivered at an incremental cost of 29 US dollars per quality-adjusted treatment-free day. A one-way sensitivity analysis confirmed the robustness of the results. CONCLUSION The experimental post-transplant care program is both effective and cost-effective; the superior results are attributed to improved QoL.

Abstract
BACKGROUND Basiliximab is a high-affinity chimeric monoclonal antibody directed against the alpha-chain of the interleukin (IL)-2 receptor. Individual studies have shown that it is highly effective in preventing acute rejection and causes no measurable incremental toxicity. However, incorporation of basiliximab immunoprophylaxis into routine practice depends upon the demonstration of benefit across treatment regimens and quantitation of the treatment effect. METHODS This study employed a meta-analysis to examine the clinical benefit of basiliximab. Parameter estimates were derived from four randomised prospective double-blind studies conducted in 93 renal transplant centres in 18 countries. A total of 1185 adult primary allograft recipients were randomised within the centres to receive either basiliximab 20mg intravenously on days 0 and 4 or placebo, in addition to double or triple immunosuppression consisting of cyclosporin-microemulsion (Neoral((R))The use of tradenames is for product identification purposes only and does not imply endorsement.), corticosteroids, and azathioprine or mycophenolate mofetil. Key clinical events included patient and graft survival, graft rejection and complications. Analysis was performed using a variable model; odds ratios and the numbers needed to treat (NNT) to benefit or to harm one patient were calculated for each principal outcome at 6 or 12 months post-transplant. RESULTS Basiliximab reduced the relative risk (RR) and absolute risk (AR) of clinical and biopsy-proven acute graft rejection across all treatment regimens. The overall RR of clinical acute graft rejection was decreased by 35% in patients receiving basiliximab. AR was reduced by 15.6% (pooled incidence: 28.8% vs 44.4%, p < 0.0001), and the NNT for efficacy was six. The reduction in RR of biopsy-proven rejection was similar (32%) with an absolute risk reduction (ARR) of 11.7% (pooled incidence: 25.1% vs 36.8%, p < 0.0001) and NNT of nine over 6 months. There was a concomitant reduction in the risk of graft loss which did not reach statistical significance (p = 0.14). The RR of graft loss was reduced by 26% with an AR reduction of 2.3% (pooled incidence: 6.4% vs 8.7%) and an NNT of 42 over 6 months. The risk of death was unchanged. CONCLUSIONS Immunoprophylaxis with basiliximab produces a significant reduction in the RR and AR of clinical and biopsy-proven acute graft rejection with a trend towards a concomitant reduction in the risk of graft loss. The magnitude of protection provided by basiliximab, the fact that it is observed across treatment regimens and the safety of this therapy are arguments for its routine use in renal transplantation.

Abstract
Living-donor nephrectomy has traditionally been performed through a flank incision with or without rib resection or by an anterior extraperitoneal incision, both of which reduce the willingness of potential donors to undergo the procedure. The first successful human laparoscopic donor nephrectomy was reported in 1995. In order to reduce warm ischemia and operative time and to make the operation safer and easier, some laparoscopic surgeons have used hand assistance. The authors describe their technique for this operation and review the results.

Abstract
The supply of kidneys does not meet the demand. As a consequence, the waiting time for a cadaver kidney continues to lengthen, and there is renewed debate about payment for living donors. To facilitate this debate, we studied what amount of payment would be cost-effective for society, i.e. what costs would be saved (if any) by removing a patient from the waiting list using a paid (living unrelated: LURD) donor-vendor. A Markov model was developed to calculate the expected average cost and outcome benefits of increasing the organ supply and reducing waiting times by adding paid LURD organs to the available pool. We found that a LURD transplant saved $94,579 (US dollars, 2002), and 3.5 quality-adjusted life years (QALYs) were gained. Adding the value of QALYs, a LURD transplant saved $269 319, assuming society values additional QALYs from transplantation at the rate paid per QALY while on dialysis. At a minimum, a vendor program would save society >$90,000 per transplant and provides QALYs for the ESRD population. Thus, society could break even while paying $90,000/kidney vendor.

Abstract
BACKGROUND International travel is associated with an increased risk of enteric, vector-borne and bloodborne infections. The risk of acquiring travel-related illness is higher in those who are immunocompromised. However, little is known about travel practices and risk behaviors in transplant recipients who travel. We herein profile transplant recipients who travel, and characterize their pre-travel precautions, travel activities, burden of illness, and exposure history. METHODS With the use of a standardized and validated questionnaire, patients attending a transplant clinic were surveyed regarding recent travel and risk behaviors. RESULTS Of 267 transplant recipients who participated, 95 (36%) indicated that they had recently traveled outside Canada and the USA. Their mean age was 49.9 years, 54% were male, and 54% were born outside Canada. Eighty-six percent of travelers were receiving at least two immunosuppressive drugs at the time of their trip. Sixty-six percent of travelers sought pre-travel advice, primarily from their transplant physician. Sixty-three percent traveled to areas where hepatitis A is endemic, but only 5% had received hepatitis A immunization. Fifty percent traveled to dengue- and malaria-endemic areas, but,25% adhered to mosquito prevention measures. Ten percent reported behaviors that exposed them to blood or body fluids, including injections, body piercing, and casual sexual activity. CONCLUSIONS Solid organ transplant recipients represent a unique group of compromised travelers; however, few were adequately protected against travel-associated enteric, vector-borne and bloodborne pathogens.

Abstract
BACKGROUND Monitoring of microemulsion ciclosporin (cyclosporine; Neoral) by 2-hour post-dose drug concentrations (C2) is an accurate measure of ciclosporin absorption efficiency and exposure, and appears superior to trough (C0) monitoring for prediction of rejection risk. A predictive decision model was used to determine if this approach also reduces total treatment costs in the first 12 months after renal transplantation. METHODS Parameter estimates for key clinical events were derived from the literature and from prospective pharmacokinetic studies comprising 234 adult HLA-non-identical renal graft recipients at seven Canadian centres. Patients were treated with microemulsion ciclosporin (Neoral), corticosteroids and azathioprine or mycophenolate mofetil. Using the perspective of the Canadian healthcare provider, total treatment costs for the C2 versus the C0 strategy were modelled over 12 months, and then remodelled using conservative estimates to extend the timeframe to 5 years. Health resources were valued in 1999 Canadian dollars. RESULTS The incidence of acute rejection was estimated to be 25% at 1 year in patients monitored by C0 and 18% in those monitored by C2. Patient survival was considered to be independent of monitoring strategy, and graft loss was predicted to be 1.4% lower in the C2 group. The studies suggested no important differences in comorbidity and the costs of C0 and C2 monitoring and ambulatory-based adverse events were held equivalent. Using these inputs, the average cost per patient for the first year post-transplant was Can dollars 46,857 for C0 monitoring and Can dollars 45,306 for C2 monitoring, rising to Can dollars 146,879 and Can dollars 142,569 after 5 years. The predicted cost for initial hospitalisation was Can dollars 11,280 for C0 and Can dollars 10,806 for C2 monitoring. The cost of maintenance immunosuppressive drug use, graft loss and dialysis was Can dollars 19,098 in the C0 group and Can dollars 18,612 in the C2 group, while acute rejection treatment costs were Can dollars 2169 and Can dollars 1577, respectively. An additional Can dollars 14,310 was consumed by other events, including repeat hospitalisation, for each group. Sensitivity analysis indicated that the most influential parameters affecting savings due to C2 monitoring were a reduction in the duration of initial and follow-up hospitalisations and reduced risks of acute rejection and subsequent graft loss. CONCLUSIONS Compared with traditional trough concentration monitoring, ciclosporin monitoring at 2 hours post-dose produced a predicted saving of Can dollars 1551 during the first year after renal transplant. Although modelling assumptions become more restrictive over time, this projection allows a preliminary assessment of the long-term economic impact of the routine use of C2 monitoring.
