OPTN/SRTR 2016 Annual Data Report: Economics.

Medicare costs vary for solid organ transplant recipients by outcome: survival with graft function, survival with graft failure, and death. Average per-person per-year reimbursement was $75 thousand for kidney recipients who survived the first year posttransplant with a functioning graft, $171 thousand for those who required a return to dialysis or retransplant, and $350 thousand for those who died with function. For pancreas recipients: $105 thousand for those who survived the first year with a functioning graft, $120 thousand for those who survived pancreas failure, and $443 thousand for those who died with function. For liver recipients: $154 thousand for those who survived with a functioning graft, $388 thousand for those who required retransplant, and $740 thousand who died with function. For intestine recipients: $301 thousand for those who survived with a functioning graft and $1 million for those who died with function. For heart recipients: $272 thousand for those who survived with a functioning graft and $1.2 million for those who died with function. For lung recipients: $196 thousand for those who survived with a functioning graft, $642 thousand for those who required retransplant, and $761 thousand for those who died with function.

OPTN/SRTR 2015 Annual Data Report: Economics.

While the costs to Medicare of solid organ transplants are varied and considerable, the total Medicare expenditure of $4.4 billion for solid organ transplant recipients in 2014 remained less than 1% of all Medicare expenditures. For patients covered by Medicare, the ratio of pre- to posttransplant cost of care varied widely by organ and within some organ categories by patient characteristics. This chapter reports pretransplant costs for all solid organ candidates covered by Medicare to allow investigators to further explore the relative cost of transplant compared with alternative management.

Economics.

While the costs to Medicare of solid organ transplants are varied and considerable, the total Medicare expenditure of $4.2 billion for solid organ transplant recipients in 2013 remains less than 1% of all Medicare expenditures. Kidney transplant remains one of the most cost-effective surgical interventions in medicine and exhibits a rare feature in that it is generally known to be cost-saving in the long term. For patients covered by Medicare, lung transplant is one of the more costly solid organ transplants performed. This chapter reports pretransplant costs for lung candidates to allow investigators to further explore the relative cost of lung transplant compared with alternative management.

Ethnic and gender related differences in the risk of end-stage renal disease after living kidney donation.

There is limited data pertaining to the risk of End Stage Renal Disease (ESRD) after living kidney donation. The Organ Procurement and Transplantation Network and the Center for Medicare and Medicaid Services databases were used to identify living kidney donors (LKDs) who subsequently developed ESRD and to calculate LKD ESRD rates. We found 126 cases of ESRD among 56 458 LKDs (0.22%) who donated during October 1, 1987-March 31, 2003. The overall LKD ESRD rate was 0.134 per 1000 years at risk, with an average duration of follow-up of 9.8 years. ESRD rates for LKDs overall and for Black, White, male and female donors compared favorably to the ESRD incidence in the general population. The LKD ESRD rate was nearly five times higher for Blacks than for Whites and two times higher for males than females. However, these ethnic and gender-related differences were similar to those previously reported for ESRD in the general population. Our findings do not show an increase in the risk of ESRD for LKDs and support the current practice of living kidney donation. Further research is needed to determine if improved donor screening or follow-up will reduce the risk of postdonation ESRD.

Access and outcomes among minority transplant patients, 1999-2008, with a focus on determinants of kidney graft survival.

Coincident with an increasing national interest in equitable health care, a number of studies have described disparities in access to solid organ transplantation for minority patients. In contrast, relatively little is known about differences in posttransplant outcomes between patients of specific racial and ethnic populations. In this paper, we review trends in access to solid organ transplantation and posttransplant outcomes by organ type, race and ethnicity. In addition, we present an analysis of categories of factors that contribute to the racial/ethnic variation seen in kidney transplant outcomes. Disparities in minority access to transplantation among wait-listed candidates are improving, but persist for those awaiting kidney, simultaneous kidney and pancreas and intestine transplantation. In general, graft and patient survival among recipients of solid organ transplants is highest for Asians and Hispanic/Latinos, intermediate for whites and lowest for African Americans. Although much of the difference in outcomes between racial/ethnic groups can be accounted for by adjusting for patient characteristics, important observed differences remain. Age and duration of pretransplant dialysis exposure emerge as the most important determinants of survival in an investigation of the relative impact of center-related versus patient-related variables on kidney graft outcomes.

MELD scores do not predict patient morbidity while on the liver transplant waiting list.

The goals of this study were to assess waitlist morbidity in terms of the frequency of health care services utilized by patients while on the liver transplant (LTX) waiting list and to determine whether that utilization can be predicted by the Model for End-Stage Liver Disease (MELD). Sixty-three noncomatose subjects were followed from waitlist placement until death, change in status, LTX, or study discontinuance. Health care events included doctor/clinic visits, labs, outpatient/inpatient tests and procedures, and hospital/intensive care unit days. Listing MELD scores and LTX MELD scores were examined against the number of health care event occurrences within 60 days of listing and 60 days of LTX, respectively, as were changes in MELD scores between listing and LTX and differences in the number of occurrences between the two time points. The only significant correlations noted were between LTX MELD scores and number of hospital days near LTX (r = .360, P = .046) and between LTX MELD scores and the sum total number of occurrences near LTX (r = .370, P = .044). These results suggest that MELD scores do not appear to predict morbidity in terms of health care utilization in patients awaiting LTX. Developing a system capable of predicting waitlist morbidity may lead to the implementation of medical interventions aimed at circumventing foreseeable complications and/or crises in patients awaiting LTX.

Sirolimus conversion after liver transplantation: improvement in measured glomerular filtration rate after 2 years.

METHODS: We reviewed our prospectively maintained database of 2005 liver transplantations. Therapy was either started de novo or converted from calcineurin inhibitors (CNIs) to sirolimus as the main immunosuppressive agent for nephrotoxicity or rejection. Glomerular filtration rate (GFR) was determined with iodine 125-labeled sodium isthalamate (Glofil-125), and serum creatinine concentration was obtained before and 3 months after transplantation, and yearly in both groups. Sirolimus levels were 10 to 15 ng/mL in patients at less than 3 months after transplantations and 5 to 10 ng/mL in the remaining patients. All patients received mycophenolate mofetil as maintenance therapy. RESULTS: Data for 29 patients in the de novo group and 35 in the conversion group were reviewed. Patients in the de novo group demonstrated an acute cellular rejection rate of 17.2%, 40% of which were steroid resistant. In this group, 48.2% discontinuation of sirolimus was necessary because of adverse effects. Patients in the conversion group demonstrated an acute cellular rejection rate of 2.8% and a 34.3% rate of sirolimus discontinuation. Seventeen (56.7%) patients at 1 year and 8 (44.4%) patients at 2 years demonstrated continued improvement in GFR. In the conversion group, case-control analysis did not demonstrate a significant difference in GFR and serum creatinine concentration (P > .05) at 1 and 2 years after conversion. At the time of review, no patients in the conversion group required hemodialysis. CONCLUSIONS: Conversion to sirolimus therapy is an effective strategy in improving renal function in patients with CNI-induced nephrotoxicity and can be done without increased rejection. Most of our patients (65.7%) tolerated sirolimus conversion. Of these, 56.7% and 44.4% demonstrated continued increase in GFR with the CNI-free regimen at 1 and 2 years, respectively. Long-term, large-population, prospective, randomized, controlled studies should further validate these results.

The use of the T tube after orthotopic liver transplantation.

An end-to-end choledochocholedochostomy (CD) over a T tube or a Roux-en-Y choledochojejunostomy (CDJ) have been the standard method of biliary reconstruction following orthotopic liver transplantation (OLTx). The objective of this study was to assess whether or not use of the T tube leads to increased biliary tract complications. Biliary tract complications were categorized as bile leak, stenosis, or obstruction that required therapeutic intervention. OLTx was performed in 161 patients over an 18-month period. Fifty-one patients were excluded from the study leaving a total of 110 patients for evaluation. Fifty-nine had their bile duct reconstructed over a T tube (CD T tube, group I) while the remaining 51 patients underwent bile duct reconstruction without a T tube (CD, group II). No difference was noted between groups I and II in their survival rate, rate of conversion to Roux-en-Y CDJ, or biliary complication rates. Our results indicate that CD (i.e., without a T tube) is both a safe and effective technique to reconstruct the biliary tract following hepatic transplantation. Routine use of a T tube with a CD anastomosis is unnecessary in most liver transplant patients. In addition, the omission of a T tube has reduced the number of radiological procedures performed at our center.

The impact of surgical complications after liver transplantation on resource utilization.

OBJECTIVE: To evaluate the impact of surgical complications on length of stay and hospital charges after liver transplantation. DESIGN: A retrospective economic evaluation of the outcomes during initial hospitalization after liver transplantation. SETTING: University hospital treating referred patients. PATIENTS: The study population was 109 patients undergoing 111 liver transplantations during fiscal year 1993. MAIN OUTCOME MEASURES: Hospital charges and length of stay during the initial hospitalization after liver transplantation. Multivariate regression methods were used to analyze the impact of surgical complications on costs. RESULTS: Of the 111 transplantations, 30 (27%) had a surgical complication that required a return to the operating room during the initial hospitalization. The effect of a surgical complication was to increase the mean hospital charges (excluding physician charges) from $150,092 to $347,728 (difference of mean, $197,636; confidence interval of difference, $114,153 to $319,326). The median length of stay was 16 days for patients without complications and 45 days for those with complications. Univariate and multivariate models suggested that surgical complications had the greatest effect on length of stay and hospital charges among the factors studied. Complications tended to occur more frequently among patients with United Network for Organ Sharing (UNOS) status 1 (42% vs 22%), but this did not reach statistical significance (P = .09). CONCLUSIONS: Surgical complications after liver transplantation have a marked impact on the cost of the procedure. The magnitude of this effect is greater than that of UNOS status, presence of rejection, or other demographic or clinical factors studied. Complications tend to occur in the most ill patients. Identifying strategies to reduce the risk of complications, particularly in patients with UNOS status 1, likely can reduce the cost of transplantation.

"Talking upstairs".

PIP: The responsibility for oral contraceptive provision by college health services was discussed at a California University; student-faculty comments are summarized. The question liability with regard to the physiological risks of the pill and negative parental attitudes was a source of much concern. It was suggested that the harmful social effects and interrupted education produced by an unwanted pregnancy should be included in university consideration of it's responsibility to the student community. The morality of premarital sexual activity was also questioned by faculty. Students responded that the pill was desired for protection and its dispensation could hardly be equated with campus morals since the individual responding to contraceptive availability was making the moral decision.^ieng

Current treatment of hepatobiliary malignancies.

In summary, it should be noted that patients with underlying chronic liver disease such as viral hepatitis have many alternatives for therapy, including resection and transplantation. It is imperative that these patients receive early referral to a center with experience in performing liver resections and the ability to perform hepatic transplantation.
