US Health Care Reform and Transplantation, Part II: impact on the public sector and novel health care delivery systems

Reliability and Validity of the Japanese Version of the Basel Assessment of Adherence to Immunosuppressive Medications Scale in Kidney Transplant Recipients

A valid and reliable instrument that can measure adherence is needed to identify nonadherent patients and to improve adherence. However, there is no validated Japanese self-report instrument to evaluate adherence to immunosuppressive medications for transplant patients. The purpose of this study was to determine the reliability and validity of the Japanese version of the Basel Assessment of Adherence to Immunosuppressive Medications Scale (BAASIS).

Methods

We translated the BAASIS into Japanese and developed the Japanese version of the BAASIS (J-BAASIS) according to the International Society of Pharmacoeconomics and Outcomes Research task force guidelines. We analyzed the reliability (test-retest reliability and measurement error) and validity of the J-BAASIS (concurrent validity with the medication event monitoring system and the 12-item Medication Adherence Scale) referring to the COSMIN Risk of Bias checklist.

Results

A total of 106 kidney transplant recipients were included in this study. In the analysis of test-retest reliability, Cohen's kappa coefficient was found to be 0.62. In the analysis of measurement error, the positive and negative agreement were 0.78 and 0.84, respectively. In the analysis of concurrent validity with the medication event monitoring system, sensitivity and specificity were 0.84 and 0.90, respectively. In the analysis of concurrent validity with the 12-item Medication Adherence Scale, the point-biserial correlation coefficient for the "medication compliance" subscale was 0.38 (P < 0.001).

Conclusions

The J-BAASIS was determined to have good reliability and validity. Using the J-BAASIS to evaluate adherence can help clinicians to identify medication nonadherence and institute appropriate corrective measures to improve transplant outcomes.

Association of the Affordable Care Act on Access to and Outcomes After Kidney or Liver Transplant: A Transplant Registry Study

BACKGROUND

To evaluate the effect of the Affordable Care Act (ACA) Medicaid expansion on payor mix among patients on the kidney and liver transplant waiting list as well as waiting list and post-transplant outcomes.

DESIGN

Using the Scientific Registry of Transplant Recipients, we performed a secondary data analysis of all patients on the kidney and liver transplant waiting list from 2007 to 2018. We described changes in payor mix by timing of state Medicaid expansion. We used competing risks models to estimate cause-specific hazard ratios for the effects of insurance and era on death/delisting and transplant. We used a Poisson regression model to estimate the effect of insurance and era on incidence rate ratio of inactivations on the waiting list. We used Cox proportional hazards models to estimate the effect of insurance and era on graft and patient survival.

RESULTS

A decade after implementation of the ACA, the prevalence of Medicaid beneficiaries listed for transplant increased by 2.5% (from 7.4% to 9.9%) for kidney and by 2.6% (15.3% to 17.9%) for liver. Expansion states had greater increases than nonexpansion states (kidney 3.8% vs 0.6%, liver 5.3% vs -1.8%). Among wait-listed patients, the magnitude of association of Medicaid insurance vs private insurance with transplant decreased over time for kidney candidates (era 1 subdistribution hazard ratio (SHR), 0.62 [95% CI, 0.60-0.64] vs era 3 SHR, 0.77 [95% CI, 0.74-0.70]) but increased for liver candidates (era 1 SHR, 0.85 [95% CI, 0.83-0.90] vs era 3 SHR 0.79 [95% CI, 0.77-0.82]). Medicaid-insured kidney and liver recipients had greater hazards of graft failure; this did not change over time (kidney: HR, 1.23 [95% CI, 1.06-1.44] liver: HR, 1.05 [95% CI, 0.94-1.17]).

CONCLUSIONS

For the millions of patients with chronic kidney and liver diseases, implementation of the ACA has resulted in only modest increases in access to transplant for the publicly insured vs the privately insured.

Use of a Bluetooth tablet-based technology to improve outcomes in lung transplantation: A pilot study

The impact of remote patient monitoring platforms to support the postoperative care of solid organ transplant recipients is evolving. In an observational pilot study, 28 lung transplant recipients were enrolled in a novel postdischarge home monitoring program and compared to 28 matched controls during a 2-year period. Primary endpoints included hospital readmissions and total days readmitted. Secondary endpoints were survival and inflation-adjusted hospital readmission charges. In univariate analyses, monitoring was associated with reduced readmissions (incidence rate ratio [IRR]: 0.56; 95% confidence interval [CI]: 0.41-0.76; P < .001), days readmitted (IRR: 0.46; 95% CI: 0.42-0.51; P < .001), and hospital charges (IRR: 0.52; 95% CI: 0.51-0.54; P < .001). Multivariate analyses also showed that remote monitoring was associated with lower incidence of readmission (IRR: 0.38; 95% CI: 0.23-0.63; P < .001), days readmitted (IRR: 0.14; 95% CI: 0.05-0.37; P < .001), and readmission charges (IRR: 0.11; 95% CI: 0.03-0.46; P = .002). There were 2 deaths among monitored patients compared to 6 for controls; however, this difference was not significant. This pilot study in lung transplant recipients suggests that supplementing postdischarge care with remote monitoring may be useful in preventing readmissions, reducing subsequent inpatient days, and controlling hospital charges. A multicenter, randomized control trial should be conducted to validate these findings.

Behavioral economics-A framework for donor organ decision-making in pediatric heart transplantation

The high discard rate of pediatric donor hearts presents a major challenge for children awaiting heart transplantation. Recent literature identifies several factors that contribute to the disparities in pediatric donor heart usage, including regulatory oversight, the absence of guidelines on pediatric donor heart acceptance, and variation among transplant programs. However, a likely additional contributor to this issue are the behavioral factors influencing transplant team decisions in donor offer scenarios, a topic that has not yet been studied in detail. Behavioral economics and decision psychology provide an excellent foundation for investigating decision-making in the pediatric transplant setting, offering key insights into the behavior of transplant professionals. We conducted a systematic review of published literature in pediatric heart transplant related to behavioral economics and the psychology of decision-making. In this review, we draw on paradigms from these two domains in order to examine how existing aspects of the transplant environment, including regulatory oversight, programmatic variation, and allocation systems, may precipitate potential biases surrounding donor offer decisions. Recognizing how human decision behavior influences donor acceptance is a first step toward improving utilization of potentially viable pediatric donor hearts.

Service Requirements of Liver Transplant Anesthesia Teams: Society for the Advancement of Transplant Anesthesia Recommendations

There are disparities in liver transplant anesthesia team (LTAT) care across the United States. However, no policies address essential resources for liver transplant anesthesia services similar to other specialists. In response, the Society for the Advancement of Transplant Anesthesia appointed a task force to develop national recommendations. The Conditions of Transplant Center Participation were adapted to anesthesia team care and used to develop Delphi statements. A Delphi panel was put together by enlisting 21 experts from the fields of liver transplant anesthesiology and surgery, hepatology, critical care, and transplant nursing. Each panelist rated their agreement with and the importance of 17 statements. Strong support for the necessity and importance of 13 final items were as follows: resources, including preprocedure anesthesia assessment, advanced monitoring, immediate availability of consultants, and the presence of a documented expert in liver transplant anesthesia credentialed at the site of practice; call coverage, including schedules to assure uninterrupted coverage and methods to communicate availability; and characteristics of the team, including membership criteria, credentials at the site of practice, and identification of who supervises patient care. Unstructured comments identified competing time obligations for anesthesia and transplant services as the principle reason that the remaining recommendations to attend integrative patient selection and quality review committees were reduced to a suggestion rather than being a requirement. This has important consequences because deficits in team integration cause higher failure rates in service quality, timeliness, and efficiency. Solutions are needed that remove the time-related financial constraints of competing service requirements for anesthesiologists. In conclusion, using a modified Delphi technique, 13 recommendations for the structure of LTATs were agreed upon by a multidisciplinary group of experts.

Transplant physician and surgeon compensation: A sample framework accounting for nonbillable and value-based work

Work relative value unit (wRVU)-based fee schedules are predominantly used by both the Centers for Medicare & Medicaid Services (CMS) and private payers to determine the payments for physicians' clinical productivity. However, under the Affordable Care Act, CMS is transitioning into a value-based payment structure that rewards patient-oriented outcomes and cost savings. Moreover, in the context of solid organ transplantation, physicians and surgeons conduct many activities that are neither billable nor accounted for in the wRVU models. New compensation models for transplant professionals must (1) justify payments for nonbillable work related to transplant activity/procedures; (2) capture the entire academic, clinical, and relationship-building work effort as part of RVU determination; and (3) move toward a value-based compensation scheme that aligns the incentives for physicians, surgeons, transplant center, payers, and patients. In this review, we provide an example of redesigning RVUs to address these challenges in compensating transplant physicians and surgeons. We define a customized RVU (cRVU) for activities that typically do not generate wRVUs and create an outcome value unit (OVU) measure that incorporates outcomes and cost savings into RVUs to include value-based compensation.

Use of Community Health Workers and Patient Navigators to Improve Cancer Outcomes Among Patients Served by Federally Qualified Health Centers: A Systematic Literature Review

Introduction: In the United States, disparities in cancer screening, morbidity, and mortality are well documented, and often are related to race/ethnicity and socioeconomic indicators including income, education, and healthcare access. Public health approaches that address social determinants of health have the greatest potential public health benefit, and can positively impact health disparities. As public health interventions, community health workers (CHWs), and patient navigators (PNs) work to address disparities and improve cancer outcomes through education, connecting patients to and navigating them through the healthcare system, supporting patient adherence to screening and diagnostic services, and providing social support and linkages to financial and community resources. Clinical settings, such as federally qualified health centers (FQHCs) are mandated to provide care to medically underserved communities, and thus are also valuable in the effort to address health disparities. We conducted a systematic literature review to identify studies of cancer-related CHW/PN interventions in FQHCs, and to describe the components and characteristics of those interventions in order to guide future intervention development and evaluation.

Method: We searched five databases for peer-reviewed CHW/PN intervention studies conducted in partnership with FQHCs with a focus on cancer, carried out in the United States, and published in English between January 1990 and December 2013.

Results: We identified 24 articles, all reporting positive outcomes of CHW/PNs interventions in FQHCs. CHW/PN interventions most commonly promoted breast, cervical, or colorectal cancer screening and/or referral for diagnostic resolution. Studies were supported largely through federal funding. Partnerships with academic institutions and community-based organizations provided support and helped develop capacity among FQHC clinic leadership and community members.

Discussion: Both the FQHC system and CHW/PNs were borne from the need to address persistent, complex health disparities among medically underserved communities. Our findings support the effectiveness of CHW/PN programs to improve completion and timeliness of breast, cervical, and colorectal cancer screening in FQHCs, and highlight intervention components useful to design and sustainability.

Access to Quaternary Care Surgery: Implications for Accountable Care Organizations

BACKGROUND

Accountable care organizations (ACOs) attempt to provide the most efficient and effective care to patients within a region. We hypothesized that patients who undergo surgery closer to home have improved survival due to proximity of preoperative and post-discharge care.

STUDY DESIGN

All (17,582) institutional American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) patients with a documented ZIP code and predicted risk, who underwent surgery at our institution (2005 to 2014), were evaluated. Google Maps calculated travel times, and patients were stratified by 1 hour of travel (local vs regional). Multivariable logistic regression and Cox proportional hazard models were used to evaluate the NSQIP risk-adjusted effects of travel time on operative morbidity, mortality, and long-term survival.

RESULTS

Median travel time was 65 minutes, with regional patients demonstrating significantly higher rates of ascites, hypertension, diabetes, disseminated cancer, >10% weight loss, higher American Society of Anesthesiologists (ASA) score, higher predicted risk of morbidity and mortality, and lower functional status (all p < 0.01). After adjusting for ACS NSQIP-predicted risk, travel time was not significantly associated with 30-day mortality (odds ratio [OR] 1.06; p = 0.42) or any major morbidities (all p > 0.05). However, survival analysis demonstrated that travel time is an independent predictor of long-term mortality (OR 1.24; p < 0.001).

CONCLUSIONS

Patients traveling farther for care at a quaternary center had higher rates of comorbidities and predicted risk of complications. Additionally, travel time predicts risk-adjusted long-term mortality, suggesting a major focus of ACOs will need to be integration of care at the periphery of their region.

Health Insurance Trajectories and Long-Term Survival After Heart Transplantation

BACKGROUND

Health insurance status at heart transplantation influences recipient survival, but implications of change in insurance for long-term outcomes are unclear.

METHODS AND RESULTS

Adults aged 18 to 64 receiving first-time orthotopic heart transplants between July 2006 and December 2013 were identified in the United Network for Organ Sharing registry. Patients surviving >1 year were categorized according to trajectory of insurance status (private compared with public) at wait listing, transplantation, and 1-year follow-up. The most common insurance trajectories were continuous private coverage (44%), continuous public coverage (27%), and transition from private to public coverage (11%). Among patients who survived to 1 year (n=9088), continuous public insurance (hazard ratio =1.36; 95% confidence interval 1.19, 1.56; P<0.001) and transition from private to public insurance (hazard ratio =1.25; 95% confidence interval 1.04, 1.50; P=0.017) were associated with increased mortality hazard relative to continuous private insurance. Supplementary analyses of 11 247 patients included all durations of post-transplant survival and examined post-transplant private-to-public and public-to-private transitions as time-varying covariates. In these analyses, transition from private to public insurance was associated with increased mortality hazard (hazard ratio =1.25; 95% confidence interval 1.07, 1.47; P=0.005), whereas transition from public to private insurance was associated with lower mortality hazard (hazard ratio =0.78; 95% confidence interval 0.62, 0.97; P=0.024).

CONCLUSIONS

Transition from private to public insurance after heart transplantation is associated with worse long-term outcomes, compounding disparities in post-transplant survival attributed to insurance status at transplantation. By contrast, post-transplant gain of private insurance among patients receiving publicly funded heart transplants was associated with improved outcomes.

Medicaid enrollment after liver transplantation: Effects of medicaid expansion

Liver transplantation (LT) recipients in the United States have low rates of paid employment, making some eligible for Medicaid public health insurance after transplant. We test whether recent expansions of Medicaid eligibility increased Medicaid enrollment and insurance coverage in this population. Patients of ages 18-59 years receiving first-time LTs in 2009-2013 were identified in the United Network for Organ Sharing registry and stratified according to insurance at transplantation (private versus Medicaid/Medicare). Posttransplant insurance status was assessed through June 2015. Difference-in-difference multivariate competing-risks models stratified on state of residence estimated effects of Medicaid expansion on Medicaid enrollment or use of uninsured care after LT. Of 12,837 patients meeting inclusion criteria, 6554 (51%) lived in a state that expanded Medicaid eligibility. Medicaid participation after LT was more common in Medicaid-expansion states (25%) compared to nonexpansion states (19%; P < 0.001). Multivariate analysis of 7279 patients with private insurance at transplantation demonstrated that after the effective date of Medicaid expansion (January 1, 2014), the hazard of posttransplant Medicaid enrollment increased in states participating in Medicaid expansion (hazard ratio [HR] = 1.5; 95% confidence interval [CI] = 1.1-2.0; P = 0.01), but not in states opting out of Medicaid expansion (HR = 0.8; 95% CI = 0.5-1.3; P = 0.37), controlling for individual characteristics and time-invariant state-level factors. No effects of Medicaid expansion on the use of posttransplant uninsured care were found, regardless of private or government insurance status at transplantation. Medicaid expansion increased posttransplant Medicaid enrollment among patients who had private insurance at transplantation, but it did not improve overall access to health insurance among LT recipients.

The Impact of Redistricting Proposals on Health Care Expenditures for Liver Transplant Candidates and Recipients

Redistricting, which means sharing organs in novel districts developed through mathematical optimization, has been proposed to reduce pervasive geographic disparities in access to liver transplantation. The economic impact of redistricting was evaluated with two distinct data sources, Medicare claims and the University HealthSystem Consortium (UHC). We estimated total Medicare payments under (i) the current allocation system (Share 35), (ii) full regional sharing, (iii) an eight-district plan, and (iv) a four-district plan for a simulated population of patients listed for liver transplant over 5 years, using the liver simulated allocation model. The model predicted 5-year transplant volumes (Share 35, 29,267; regional sharing, 29,005; eight districts, 29,034; four districts, 28,265) and a reduction in overall mortality, including listed and posttransplant patients, of up to 676 lives. Compared with current allocation, the eight-district plan was estimated to reduce payments for pretransplant care ($1638 million to $1506 million, p < 0.001), transplant episode ($5607 million to $5569 million, p < 0.03) and posttransplant care ($479 million to $488 million, p < 0.001). The eight-district plan was estimated to increase per-patient transportation costs for organs ($8988 to $11,874 per patient, p < 0.001) and UHC estimated hospital costs ($4699 per case). In summary, redistricting appears to be potentially cost saving for the health care system but will increase the cost of performing liver transplants for some transplant centers.

Compensating the transplant professional: time for a model change

Compensation models for physicians are currently based primarily on the work relative value unit (wRVU) that rewards productivity by work volume. The value-based payment structure soon to be ushered in by the Centers for Medicare and Medicaid Services rewards clinical quality and outcomes. This has prompted changes in wRVU value for certain services that will result in reduced payment for specialty procedures such as transplantation. To maintain a stable and competent workforce and achieve alignment between clinical activity, growth imperatives, and cost effectiveness, compensation of transplant physicians must evolve toward a matrix of measures beyond the procedure-based activity. This personal viewpoint proposes a redesign of transplant physician compensation plans to include the "virtual RVU" to recognize and reward meaningful clinical integration defined as hospital-physician commitment to specified and measurable metrics for current non-RVU-producing activities. Transplantation has been a leader in public outcomes reporting and is well suited to meet the challenges ahead that can only be overcome with a tight collaboration and alignment between surgeons, other physicians, support staff, and their respective institution and leadership.

Cancer screening at a federally qualified health center: a qualitative study on organizational challenges in the era of the patient-centered medical home

Federally Qualified Health Centers (FQHCs) serve uninsured and minority populations, who have low cancer screening rates. The patient-centered medical home (PCMH) model aims to provide comprehensive preventive services, including cancer screening, to these populations. Little is known about organizational factors influencing the delivery of cancer screening in this context. We conducted 18 semi-structured interviews with clinic personnel at four FQHC clinics in Washington State. All interviews were recorded and transcribed verbatim and analyzed by two bilingual coders to identify salient themes. We found that screening on-site, scheduling separate visits for preventive care, and having non-provider staff recommend and schedule screening services facilitated the delivery of cancer screening. We found work overload to be a barrier to screening. To successfully implement screening strategies within the PCMH model, FQHCs must enhance facilitators and address organizational gaps in their cancer screening processes.

Opportunities for improving cancer prevention at federally qualified health centers

As the Affordable Care Act unfolds, federally qualified health centers (FQHCs) will likely experience an influx of newly insured, low-income patients at disparate risk for cancer. Cancer-focused organizations are seeking to collaborate with FQHCs and the Primary Care Associations (PCAs) that serve them, to prevent cancer and reduce disparities. To guide this collaboration, we conducted 21 interviews with representatives from PCAs and FQHCs across four western states. We asked about: FQHC priorities, barriers and facilitators to cancer prevention, the PCA-FQHC relationship, and collaboration opportunities for external organizations. FQHC priorities include medical home transformation, electronic health records, and clinical care; prevention efforts must integrate with these. Barriers to cancer prevention include competing priorities, inadequate patient insurance, and lack of reimbursement, while facilitators are the presence of patient navigators and cancer-related performance measures. Collaboration opportunities for external organizations include dissemination of culturally appropriate educational materials and support for patient navigators.

The transplant center and business unit as a model for specialized care delivery

Transplant centers are valuable assets to a transplantation hospital and essential to organize the delivery of patient care. A transplant center defined around physicians and activities of caring for patients with organ failure creates a team better equipped to manage care across the continuum of the diseases treated by transplantation. Through monitoring of clinical and financial outcomes, the transplant center can better respond to the changing regulatory and financial landscape of health care. This article seeks to explain the major organizational challenges facing the transplant center and how a transplant center can best serve its patients and parent organization.

Factors predictive of medication nonadherence after renal transplantation: a French observational study

BACKGROUND

There have been few prospective studies on the natural history of nonadherence (NA) in kidney transplant recipients (KTRs) over time. The objective of this study was to prospectively evaluate the rate of and risk factors for NA in a French cohort of KTRs.

METHOD

A total of 312 KTRs from eight French transplantation centers were included in this prospective, noninterventional cohort study. A computer-learning software package (the Organ Transplant Information System) was made available to all patients.

RESULTS

Using the four-item Morisky scale, we showed that 17.3%, 24.1%, 30.7%, and 34.6% of patients were nonadherent at posttransplant month 3 (M3), M6, M12, and M24, respectively. Young age was predictive of NA at M6, M12, and M24. Surprisingly, simple treatment regimens including a small number of doses per day and a small number of tablets per day were associated with NA at M3 and M12, respectively. Other factors predictive of NA included failure to use the Organ Transplant Information System software package at M6 and patient reports of adverse events at M12 and M24. Importantly, we observed that physicians underestimated the prevalence of adverse events when compared to patient self-reporting.

CONCLUSION

Our observed rate of medication NA in France is consistent with rates reported in previous studies. We found variability in NA risk factors over time as well as an unexpected risk factor (simple treatment regimens). These findings will be useful in developing effective adherence-promoting interventions.

Centre volume and resource consumption in liver transplantation

BACKGROUND

Using SRTR/UNOS data, it has previously been shown that increased liver transplant centre volume improves graft and patient survival. In the current era of health care reform and pay for performance, the effects of centre volume on quality, utilization and cost are unknown.

METHODS

Using the UHC database (2009-2010), 63 liver transplant centres were identified that were organized into tertiles based on annual centre case volume and stratified by severity of illness (SOI). Utilization endpoints included hospital and intensive care unit (ICU) length of stay (LOS), cost and in-hospital mortality.

RESULTS

In all, 5130 transplants were identified. Mortality was improved at high volume centres (HVC) vs. low volume centres (LVC), 2.9 vs. 3.4%, respectively. HVC had a lower median LOS than LVC (9 vs. 10 days, P < 0.0001), shorter median ICU stay than LVC and medium volume centres (MVC) (2 vs. 3 and 3 days, respectively, P < 0.0001) and lower direct costs than LVC and MVC ($90,946 vs. $98,055 and $101,014, respectively, P < 0.0001); this effect persisted when adjusted for severity of illness.

CONCLUSIONS

This UHC-based cohort shows that increased centre volume results in improved long-term post-liver transplant outcomes and more efficient use of hospital resources thereby lowering the cost. A better understanding of these mechanisms can lead to informed decisions and optimization of the pay for performance model in liver transplantation.

Acute Care Nurse Practitioners in Transplantation: Adding Value to Your Program

Nurse practitioners are nurses who are prepared at the graduate level. They exercise autonomy in clinical decision making, perform physical examinations and obtain health histories, diagnose and treat a variety of illnesses, provide education and counseling to patients, perform procedures, and ultimately provide cost-effective care. The role of the nurse practitioner evolved in the 1960s, when nurse practitioners filled a void in response to the nationwide shortage of physicians. Today, nurse practitioners specialize both by degree and by certification examination. There are several types of nurse practitioners, including acute care, adult, family practice, and pediatric. The incorporation of acute care nurse practitioners (ACNPs) in transplant programs is an emerging field and varies across the country from center to center. The goals of this article are to (1) identify implications for ACNPs in transplant, (2) discuss the value of using ACNPs in practice, and (3) explore billing and regulatory aspects of ACNPs in transplant programs.

The crossroads of evidence-based medicine and health policy: implications for urology

As healthcare spending in the United States continues to rise at an unsustainable rate, recent policy decisions introduced at the national level will rely on precepts of evidence-based medicine to promote the determination, dissemination, and delivery of "best practices" or quality care while simultaneously reducing cost. We discuss the influence of evidence-based medicine on policy and, in turn, the impact of policy on the developing clinical evidence base with an eye to the potential effects of these relationships on the practice and provision of urologic care.

The economic implications of broader sharing of liver allografts

Liver transplantation has evolved over the past four decades into the most effective method to treat end-stage liver failure and one of the most expensive medical technologies available. Accurate understanding of the financial implication of recipient severity of illness is crucial to assessing the economic impact of allocation policies. A novel database of linked clinical data from the Organ Procurement and Transplantation Network with cost accounting data from the University HealthSystem Consortium was used to analyze liver transplant costs for 15,813 liver transplants. This data was then utilized to consider the economic impact of alternative allocation systems designed to increase sharing of liver allografts using simulation results. Transplant costs were strongly associated with recipient severity of illness as assessed by the MELD score (p < 0.0001); however, this relationship was not linear. Simulation analysis of the reallocation of livers from low MELD patients to high MELD using a two-tiered regional sharing approach (MELD 15/25) resulted in 88 fewer deaths annually at estimated cost of $17,056 per quality-adjusted life-year saved. The results suggest that broader sharing of liver allografts offers a cost-effective strategy to reduce the mortality from end stage liver disease.
