OPTN/SRTR 2019 Annual Data Report: Liver
Abstract
This year was notable for changes to exception points determined by the geographic median allocation Model for End-Stage Liver Disease (MELD) and implementation of the National Liver Review Board, which took place on May 14, 2019. The national acuity circle liver distribution policy was also implemented but reverted to donor service area- and region-based boundaries after 1 week. In 2019, growth continued in the number of new waiting list registrations (12,767) and transplants performed (8,896), including living-donor transplants (524). Compared with 2018, living-donor liver transplants increased 31%. Women continued to have a lower deceased-donor transplant rate and a higher pretransplant mortality rate than men. The median waiting time for candidates with a MELD of 15-34 decreased, while the number of transplants performed for patients with exception points decreased. These changes may have been related to the policy changes that took effect in May 2019, which increased waiting list priority for candidates without exception status. Hepatitis C continued to decline as an indication for liver transplant, as the proportion of liver transplant recipients with alcohol-related liver disease and clinical profiles consistent with non-alcoholic steatohepatitis increased. Graft and patient survival have improved despite changing recipient demographics including older age, higher MELD, and higher prevalence of obesity and diabetes.
Adult Transplant
Waiting List Registration
There were 13,093 candidates on the liver transplant waiting list at the start of the year and 12,767 new registrations and 13,298 removals during the year, leaving 12,562 candidates waiting as of December 31, 2019 (Figure LI 1, Table LI 4).
The proportion of older (aged ≥65 years) candidates continued to increase, representing 20.8% of the adult waiting list in 2019, compared with 8.9% in 2009 (Figure LI 3). The number of candidates aged 50-64 years has decreased steadily over the past 6 years, although this age-group continued to make up over half (53.8%) of adults on the waiting list. The sex and racial composition of the waiting list has remained relatively unchanged: 61.8% male and 38.2% female, 68.9% white, 7.0% black, 17.5% Hispanic, and 5.0% Asian (Figure LI 4, Figure LI 5).
The proportion of candidates with a primary diagnosis of hepatitis C virus (HCV) continued to decline, making up 12.6% of new registrations, compared with 30.6% 10 years before. Meanwhile, the proportions with alcohol-related liver disease and other/unknown diagnosis continued to increase (to 31.3% and 35.6%, respectively) (Figure LI 6). The other/unknown category likely represents candidates with liver disease due to non-alcoholic steatohepatitis. The proportion of candidates with acute liver failure and cholestatic liver disease have also declined in the past 10 years, making up only 2.1% and 7.8% of new registrations, respectively, in 2019. Candidates with a primary diagnosis of hepatocellular carcinoma (HCC) comprised 10.6% of new waiting list registrations.
The severity of liver disease, based on the first active laboratory Model for End-Stage Liver Disease (MELD) during the calendar year, has increased (Figure LI 7). Most patients had an initial MELD <15 (47.1%), but an increasing proportion had an initial MELD 15-24 (36.3%), MELD 25-34 (11.3%), and MELD 40+ (2.4%). Candidates with body mass index (BMI) ≥35 kg/m2 comprised 17.3% of the waiting list, representing the only BMI category with a steadily increasing trend (Figure LI 8). Candidates with a previous liver transplant made up only 3.1% of the waiting list, down from 4.5% in 2009 (Figure LI 10).
The proportion of adults willing to accept HCV-positive donors now has surpassed those unwilling to accept them (51.4% v. 48.6%, respectively), reflecting a distinct shift in attitudes compared with just 5 years before and the willingness of HCV-uninfected patients to accept HCV-positive donors in the direct-acting antiviral (DAA) era (Figure LI 11).
Waiting List Outcomes
The overall deceased-donor transplant rate among adult waiting list candidates was 61.3 per 100 waiting list-years, continuing the upward trend that started in 2013 (Figure LI 12). The increase occurred regardless of age category, sex, blood type, or place of residence (metropolitan versus non-metropolitan) (Figure LI 13, Figure LI 15, Figure LI 17, Figure LI 18). Women had a lower deceased-donor transplant rate than men (55.8 v. 64.9 per 100 waiting list-years, respectively).
The deceased-donor transplant rate for candidates with HCC exception points remained higher than those without HCC exception (94.3 vs. 58.3 per 100 waiting list-years). Nonetheless, the transplant rate for patients with HCC exception is over 50% lower than it was 10 years before (193.4 per 100 waiting list-years). During this time period, multiple adjustments to the assignment of HCC exception points have been implemented, including standardized size and serum alpha-fetoprotein criteria, a mandatory 6-month waiting period after the initial application, a 34-point exception cap, and replacement of the “point escalator” with a static score based on median allocation MELD at transplant updated every 6 months. Compared with 2018, the deceased-donor transplant rate among patients without HCC exception increased from 50.5 to 58.3 per 100 waiting list-years (Figure LI 16).
The median waiting time (time from listing to transplant) remained low for candidates listed with the greatest medical urgency: 0.23 months for those with MELD ≥35, and 0.16 months for those listed as status 1A (Figure LI 20). The median waiting time for candidates with MELD 15-34 dropped from 8.5 to 5.6 months. Of waiting list registrants listed in 2018, 49.0% received a deceased-donor liver transplant within 1 year (Figure LI 21). Figure LI 19 shows 3-year outcomes for adults listed for liver transplant in 2016: 56.0% received a transplant (including 2.2% from a living donor), 11.3% died, and 23.3% were removed from the list without undergoing transplant, leaving 9.4% still waiting.
Geographic differences in deceased-donor transplant rates persisted, ranging from 35% to 90% at 3 years by donation service area (DSA) (Figure LI 22) and 31% to 86% by state of residence (Figure LI 23). DSA-level pretransplant mortality rates also varied, with a median of 13.3 per 100 waiting list-years (IQR 10.8-16.1) (Figure LI 33).
The overall pretransplant mortality rate in 2019 was 12.3 per 100 waiting list-years, down from a peak of 17.9 per 100 waiting list-years 5 years before (Figure LI 24). Higher rates of pretransplant mortality were observed among older age groups and those listed with higher initial laboratory MELD (Figure LI 25, Figure LI 30). Differences remained in pretransplant mortality rate by sex (11.4 per 100 waiting list-years for men, versus 13.8 for women) and by candidate residence (12.0 per 100 waiting list-years for metropolitan, versus 13.9 for non-metropolitan) (Figure LI 27, Figure LI 29). Pretransplant mortality among patients with HCV dropped from 16.8 to 8.5 per 100 waiting list-years over the past 5 years, reflecting the efficacy of DAA therapy, even among waiting list registrants (Figure LI 28). Pretransplant mortality among candidates with alcohol-related liver disease and HCC also dropped by a similar margin during that period. Candidates with acute liver failure and other/unknown etiology (usually non-alcoholic steatohepatitis) had higher rates of pretransplant mortality than other etiologies (22.4 and 15.4 per 100 waiting list years, respectively). Pretransplant mortality rate was similar between candidates with and without HCC exception, as well as between those with active and inactive status (Figure LI 31, Figure LI 32).
The most common reason for waiting list removal was deceased- or living-donor transplant (62.4%), followed by death or being too sick for transplant (18.1%), other reasons (12.0%), and condition improved and transplant no longer needed (6.7%) (Table LI 5). Deaths within 6 months after removal among waiting list candidates increased to 21.1%, compared with 16.9% in 2018, regardless of age or medical urgency category (Figure LI 34, Figure LI 35, Figure LI 36).
Donation
The number of deceased-donor livers recovered reached an all-time high of 9151 in 2019. Compared with previous years, there were no major differences in age, sex, or race (Figure LI 40, Figure LI 41, Figure LI 42). The availability of HCV-positive organs continued to increase, representing 9.7% of deceased-donor livers in 2019 (Figure LI 39, Figure LI 43).
Over the past decade, fewer pediatric (aged <18 years) livers were used for adult liver transplants, from 11.7% in 2009 to 7.7% in 2019 (Figure LI 40). This may decline further with the implementation of acuity circles and increased priority for pediatric donor livers to be allocated to pediatric recipients. Depending on the donor-specific antibodies, the allocation of pediatric donor livers to adults was 23.9% to 76.0% (Figure LI 44).
The organ discard rate (percentage of organs recovered for transplant and not transplanted) increased from 8.6% in 2018 to 9.6% in 2019 (Figure LI 45). This was driven by increased discard of grafts from donors aged ≥55 years and, to a lesser extent, those of donors aged 30-54 years. As expected, deceased-donor livers from older donors were less likely to be transplanted (Figure LI 46). As has been true since 2016, HCV-positive donors were not discarded more often than HCV-negative donors (Figure LI 50). Livers recovered from donors after circulatory death remained four times more likely to be discarded than livers recovered from donors after brain death (29.9% versus 7.1%, respectively) (Figure LI 52).
Amid the ongoing opioid epidemic in the United States, the proportion of donors with anoxic brain injury continued to rise, representing the leading cause of death among deceased donors (43.8%) (Figure LI 53). Head trauma and cerebrovascular accidents, respectively, were the second and third most common causes of death.
In 2019, 524 living-donor liver transplants were performed, a 31% increase over the year before (Figure LI 55, Figure LI 62). Most living donors were aged 18-54 years (Figure LI 56). An increasing proportion of living donors met criteria for obesity with a BMI ≥30 kg/m2 (20.5%), although fewer than 1% of living donors had a BMI ≥35 (Figure LI 60). Right-lobe donation represented most living-donor liver transplants (71.3%) (Figure LI 59). The readmission rate for living liver donors who donated between 2014-2018 was 10.5% at 6 months and 12.5% at 12 months (Figure LI 54). Reported complications among living liver donors who donated between 2015-2019 included biliary complications (2.8%), vascular complications requiring intervention (0.8%), re-operation (2.0%), and other complications requiring intervention (6.2%) (Table LI 6). Of these same donors, 1.0% experienced Clavien Grade 1 complications, 1.5% had Clavien Grade 2, and 0.4% had Clavien Grade 3.
Transplants
In 2019, 8896 liver transplants were performed in the United States, more than in any previous year (Figure LI 61). This represented a 7.8% increase over the previous year and a 40.8% increase from 10 years earlier. The proportion of living-donor liver transplants continued to increase, making up 5.3% of all transplants in 2019 (Figure LI 62, Table LI 5). Most liver transplant recipients (69.6%) were aged >50 years, while 21.6% were ≥65 years (Figure LI 63); 8345 were adults (≥18 years), 442 (5.3%) of whom received living-donor transplants.
The number of liver transplants performed for alcohol-related liver disease and other/unknown disease (often non-alcoholic steatohepatitis) continued to rise in 2019, representing the two most common diagnoses and most transplants (65.1%) (Figure LI 66). Liver transplants for HCC, the third most common diagnosis, decreased from 16.0% to 14.0% compared with 2018. The proportion of liver transplants performed for HCV continued to fall, representing only 7.3% of transplants, down from 24.0% in 2014. Patients with HCV may still be represented among transplant recipients with a primary diagnosis of HCC.
Of adult liver transplant recipients, 63.7% were male; additionally, 70.7% were white, 16.0% were Hispanic, and 7.3% were black (Figure LI 64, Figure LI 65, Table LI 8). Coincident with the increased prevalence of non-alcoholic steatohepatitis, 37.7% were obese (BMI ≥30 kg/m2), and 30.0% had diabetes, compared with 33.6% and 25.6%, respectively, in 2009 (Table LI 9). From 2009 to 2019, the proportion of adult liver transplants covered by public insurance increased (22.4% to 30.0% for Medicare; 13.8% to 15.4% for Medicaid), while fewer transplants were covered by private insurance (59.4% to 50.8%) (Table LI 8). Regarding medical urgency, 20.4% of adults were transplanted with MELD ≥35, 18.4% with MELD 30-34, 53.0% with MELD 15-29, 5.6% with MELD <15, and 2.5% as status 1A (Table LI 9). Among adult liver transplant recipients, 34.9% waited fewer than 31 days on the waiting list, and 83.5% waited less than 1 year; 10.5% waited 1-2 years, 2.6% waited 2-3 years, and 3.4% waited ≥3 years (Table LI 10).
In 2019, 28.0% of adult liver transplant recipients had exception points, compared with 33.3% in 2018, potentially related to the policy change implemented mid-year, which changed the exception review structure and assigned fewer points for most exceptions. Of adult liver transplant recipients, 17.7% had MELD exception points for HCC, a decrease from 24.1% in 2009 and 20.4% in 2018 (Table LI 9).
Only 301 (3.6%) of adult liver transplant recipients had a previous liver transplant in 2019, compared with 414 (7.2%) in 2009 (Table LI 10). Of all liver transplants, 787 (9.4%) were multi-organ, most of which were simultaneous liver-kidney transplants (704, compared with 347 in 2009, Figure LI 67). There were 96 split livers (1.2%), unchanged from previous years, and 712 (8.5%) livers donated after circulatory death, an increase from 285 (5.0%) in 2009 and 531 (6.9%) in 2018.
From 2017 to 2019, 9.0% of livers transplanted to adults were from donors with positive HCV antibodies, and 5.9% were positive on HCV nucleic acid testing. Of adult liver transplant recipients without a history of HCV based on a negative antibody test, 4.2% received a liver from an HCV antibody-positive donor, while 2.5% received one from a donor positive for HCV on nucleic acid testing (Table LI 11).
Geographic variability in terms of median allocation MELD among adult deceased-donor liver transplant recipients was 19 to 36 across 52 DSAs (Figure LI 70). The highest was reported in New York (NYFL), and the lowest in Arkansas (AROR). The median DSA-level MELD at transplant was 26, down from 28 in the preceding 3 years (Figure LI 71). The interquartile range was wider (IQR 24.0-29.5), suggesting persistent geographic variability.
The National Liver Review Board was recently established to better standardize exceptions. As of May 2019, each center’s median allocation MELD at transplant now determines the number of MELD exception points given to qualifying candidates. In 2019, the median proportion of patients given exception points was 25.5% at the DSA-level (IQR 21.1-33.4%) (Figure LI 72).
In 2019, 127 programs performed adult liver transplants, and the median transplant program volume increased to 55 transplants per year (IQR 24-104) (Figure LI 74). Induction therapy was used in only 28% of adult liver transplants, and 71.0% of adult liver transplant recipients received steroid-containing immunosuppressive regimens (Figure LI 68, Figure LI 69).
Outcomes
Long-term outcomes after liver transplant continued to improve. Graft failure occurred in 6.6% of deceased-donor liver transplant recipients at 6 months and 8.9% at 1 year for transplants performed in 2018, in 15.2% at 3 years for transplants performed in 2016, in 21.6% at 5 years for transplants performed in 2014, and in 42.6% at 10 years for transplants performed in 2009 (Figure LI 76). Outcomes were similar, if not better, for living-donor liver transplant recipients, with graft failure occurring in 5.9% at 6 months, 7.1% at 1 year, 13.8% at 3 years, 23.7% at 5 years, and 32.1% at 10 years (Figure LI 77). Patient survival demonstrated similar patterns, with 5.3% mortality at 6 months, 7.4% at 1 year, 13.1% at 3 years, 19.7% at 5 years, and 39.5% at 10 years (Figure LI 78).
Five-year graft survival rates among deceased-donor liver transplant recipients exceeded 75% for all age groups except those aged ≥65 years (72.3%) and for all BMI categories except <18.5 kg/m2 (Figure LI 79, Figure LI 84). Five-year graft survival rates were lower for recipients of livers donated after circulatory death than for those receiving livers donated after brain death (72.6% v. 77.1%) and comparable between those with and without HCC exception points (76.6% v. 77.0%) (Figure LI 82, Figure LI 83). Whereas deceased-donor liver transplant recipients with a primary diagnosis of HCC had 5-year survival rates comparable to other disease etiologies (75.2%), living-donor liver transplant recipients with HCC demonstrated worse 5-year survival rates (61.8%) (Figure LI 80, Figure LI 88). Five-year graft survival rates for deceased-donor liver transplant recipients with HCV were comparable to other etiologies of liver disease, which may point to the effectiveness of oral DAA agents for HCV introduced in 2013. Adult patient survival after deceased-donor liver transplant largely mirrored that of graft survival (Figure LI 95, Figure LI 96, Figure LI 97, Figure LI 98).
As of June 30, 2019, 93,761 liver transplant recipients were alive with a functioning graft, 82,304 of whom received a liver transplant as adults (Figure LI 91). Within 1 year, 12.3% of liver transplant recipients in 2017-2018 experienced at least one episode of acute rejection, most often among younger recipients (Figure LI 92). About 1% of adult liver recipients developed posttransplant lymphoproliferative disorder over 5 years (Figure LI 94).
Pediatric Transplant
Summary
As has been true in the past, 60% of all children listed for liver transplant in 2019 were aged 5 years or younger, and the highest rate of pretransplant mortality persisted for children aged younger than 1 year. This rate was persistently higher than rates for all adults, despite use of split and other technical variant grafts, high rates of exception scores, and living donation. Children are undergoing transplant at higher acuity than in the past, as evidenced by higher MELD/pediatric end-stage liver disease (PELD) scores and listings at status 1A and 1B. Higher acuity at transplant is likely due to lack of access to suitable donor organs, as dictated by current policy, which has been compensated for by persistent trends toward use of partial or split liver grafts and ABO-incompatible grafts. Despite higher illness severity scores at transplant, graft and patient survival posttransplant have improved over time.
Waiting List
In 2019, 686 new candidates were added to the pediatric liver transplant waiting list (Figure LI 104). The number of prevalent candidates (on the list on December 31 of the given year) continued a slow decrease to 462 overall (Table LI 16). Children aged younger than 1 year (29.9%) and 1-5 years (29.9%) made up the largest age groups, followed by ages 12-17 (24.4%) and 6-11 years (15.8%) (Figure LI 106). White candidates continued to make up the largest racial/ethnic group on the waiting list in 2019 (48.7%), followed by Hispanic (24.3%), Black (16.1%), and Asian candidates (7.6%) (Figure LI 107). For pediatric liver waitlist candidates from 2009 to 2019, sex, race, diagnosis, and geographic distributions changed little (Table LI 13, Table LI 14). Medical urgency has changed over time, with an increase in the proportions listed as status 1A and 1B. The proportion of candidates on the waiting list with exception status increased notably, to 27.6% in 2019, compared with 13.9% a decade earlier (Table LI 14). Waiting time shifted such that 55.0% of candidates waited less than 1 year in 2019, compared with 45.1% in 2009 (Table LI 15). Proportions of candidates listed for multi-organ transplants including liver have increased over time. Proportions of liver-kidney transplant candidates have increased from 1.3% to 3.1% over the past decade. The proportion of liver-pancreas-intestine transplant candidates increased from 7.9% in 2009 to 13.3% in 2019 (Table LI 15). Among candidates removed from the waiting list in 2019, 65.2% underwent deceased donor transplant, 11.1% underwent living donor transplant, 3.9% died, 11.7% were removed from the list because their condition improved, and 2.0% were considered too sick to undergo transplant (Table LI 17). Among newly listed candidates in 2016, 67% underwent deceased donor transplant within 3 years, 9% underwent living donor transplant, 5% died, 14% were removed from the list, and 5% were still waiting (Figure LI 109). In 2019, the rate of deceased donor transplants among pediatric candidates continued to increase, reaching 100.2 per 100 waitlist-years compared with 67.5 in 2008 (Figure LI 110). Transplant rates were highest for candidates aged younger than 1 year, 148.4 per 100 waitlist-years. The lowest rates were for candidates aged 12 to 17 years, 57.8 per 100 waitlist-years (Figure LI 111). Regarding medical urgency status, as expected, transplant rates were highest for status 1A (516.8 per 100 waitlist-years) and status 1B candidates (480.4 per 100 waitlist-years) (Figure LI 114). Among candidates listed with MELD/PELD scores, rates were similar for those with MELD/PELD 35 or higher and MELD/PELD 30-34, 154.6 and 172.3 transplants per 100 waitlist years, respectively, compared with 78.1 for those with MELD/PELD below 15 (Figure LI 113). Pretransplant mortality remained stable at 6.9 deaths per 100 waitlist-years in 2019 (Figure LI 116). The pretransplant mortality rate was highest for candidates aged younger than 1 year at 12.1 deaths per 100 waitlist-years in 2019, and lowest for candidates aged 1-5 years, at 3.9 deaths per 100 waitlist-years (Figure LI 117).
Transplant
The number of pediatric liver transplants has remained remarkably stable, with 551 transplants in 2019 (Figure LI 120), of which 79 (14.3%) were living donor liver transplants (Figure LI 121). Recipients aged younger than 6 years underwent the highest proportion of transplants from living donors, 18.1% (Figure LI 124). In 2019, 22 programs were performing pediatric-only liver transplants, compared with 88 performing adult-only transplants and 33 performing transplants in both adults and children (Figure LI 125). In 2019, 6.2% of transplants in candidates aged 0-10 years, 7.8% in those aged younger than 15 years, and 8.9% in those aged younger than 18 years were performed at programs with volumes of five or fewer pediatric transplants in that year (Figure LI 126). In 2019, 20.3% of liver transplants in pediatric recipients were split-liver transplants, compared with 14.4% a decade ago (Figure LI 127). The proportion of pediatric transplant recipients who underwent transplant by exception was 74.7%, compared with 28.7% among adult recipients (Figure LI 128). Among pediatric transplant recipients 2017-2019, percentages with exception points by DSA ranged from 28.6% to 100% (Figure LI 129). Despite use of exception scores, split grafts, and living donors, rates of pretransplant mortality were highest of all age groups for candidates aged younger than 1 year.
Over the past decade, recipient age, sex, and racial distributions have changed little, although fewer recipients were aged younger than 1 year (25.8% in 2017-2019 compared with 30.3% in 2007-2009) (Table LI 18). Cholestatic biliary atresia remained the leading cause of liver failure (33.5%) (Table LI 19). Most pediatric liver transplant recipients were not hospitalized before transplant (64.3%) and fewer were in the intensive care unit, 17.4% in 2017-2019 versus 25.6% in 2007-2009. Regarding medical urgency status, over the past decade, proportions of recipients undergoing transplant at status 1B increased. The proportion undergoing transplant with a MELD/PELD of 30 or higher increased from 29.1% to 44.4% over the past 10 years. MELD/PELD exception use increased from 27.5% in 2007-2009 to 47.9% in 2017-2019. Types of liver transplant procedures in pediatric recipients changed little over the past decade; 61.2% of patients received a whole liver in 2017-2019 and 19.5% received a partial liver (i.e., less than a whole liver was transplanted, possibly from a living donor, and the remainder of the liver was discarded) (Table LI 20). Use of split livers increased from 15.5% in 2007-2009 to 19.3% in 2017-2019. ABO-incompatible liver transplants occurred in 5.4% of recipients in 2017-2019, increased from 3.5% in the earlier era. Over the past decade, proportions of pediatric liver transplant recipients undergoing a liver-alone transplant increased from 84.2% in 2007-2009 to 91.5% in 2017-2019 (Table LI 20).
Immunosuppression and Outcomes
In 2019, 61% of pediatric liver transplant recipients received no induction therapy (Figure LI 130). The most commonly used initial immunosuppression regimens were tacrolimus, MMF, and steroids (39.4%) and tacrolimus and steroids (33.9%) (Figure LI 131).
Graft survival continued to improve over the past decade among pediatric recipients of deceased donor and living donor livers. Graft failure occurred in 6.2% at 6 months and in 7.8% at 1 year among deceased donor liver transplants performed in 2018, in 13.9% at 3 years for transplants performed in 2016, in 15.9% at 5 years for transplants performed in 2014, and in 24.8% at 10 years for transplants performed in 2009 (Figure LI 133). Graft failure occurred in 6.5% of recipients at 6 months and in 6.5% at 1 year posttransplant among living donor transplants performed in 2018, in 6.5% at 3 years for transplants performed in 2016, in 9.6% at 5 years for transplants performed in 2014, and in 17.6% at 10 years for transplants performed in 2009 (Figure LI 134). By age, 5-year graft survival was 81.1% for recipients aged younger than 1 year, 82.4% for ages 1-5 years, 85.3% for ages 6-10 years, and 85.5% for ages 11-17 years (Figure LI 135). Five-year graft survival was 83.5% for recipients who underwent transplant with MELD/PELD below 15 (Figure LI 137). In 2017-2018, incidence of acute rejection by 1 year posttransplant was 25.4% overall, varying from 21.3% in recipients aged younger than 1 year to 29.4% in those aged 1-5 years (Figure LI 139). Incidence of posttransplant lymphoproliferative disorder was 4.7% at 5 years posttransplant for recipients who were EBV negative and 3.1% for those who were positive (Figure LI 140). Among pediatric liver transplants 2012-2014, overall 5-year patient survival was 89.3% with little variation by age at transplant (Figure LI 142, Figure LI 143). By primary diagnosis, 5-year patient survival ranged from 93% for those with acute liver failure and biliary atresia to 81% for those with hepatoblastoma (Figure LI 144). Patient death occurred in 3.7% of recipients at 6 months and in 4.6% at 1 year posttransplant for transplants performed in 2018, in 9.4% at 3 years for transplants performed in 2016, in 9.2% at 5 years for transplants performed in 2014, and in 18.2% at 10 years for transplants performed in 2009 (Figure LI 141).
