Waiting List Patients Research Articles

Longitudinal analysis of transplant candidates with primary sclerosing cholangitis in an Asian liver transplant center.

Primary sclerosing cholangitis (PSC) is a rare disease in Asia, and few studies have investigated the disease in this ethnicity, particularly in wait-listed patients for liver transplantation (LT). We aimed to investigate the prognostic factors and outcomes of wait-listed patients with PSC in an Asian transplant center. Survival was retrospectively analyzed. Eighteen (10 male and 8 female) wait-listed patients with PSC, with a median age at diagnosis of 44.5 years, were included. Compared with men, women had significantly higher aspartate aminotransferase to platelet ratio index scores (3.28 vs. 1.13; P = 0.012) and bilirubin levels (7.68 vs. 4.03 mg/dl; P = 0.043) and more often presented with decompensating events, including ascites [5 (63%) vs. 1 (10%); P = 0.043] and splenomegaly [8 (100%) vs. 4 (40%); P = 0.013]. Compared with the non-LT group, the LT group exhibited a superior survival rate for women ( P = 0.004) but not for men. In the univariable analysis, significant risk factors associated with overall survival included malignancies with a hazard ratio (95% confidence interval) of 5.53 (1.00-30.51) and esophageal varices (EV) [4.18 (1.05-16.61)], whereas female gender [25.00 (1.49-500.00)], LT [0.09 (0.01-0.80)] and EV [39.03 (2.92-521.96)] were indicated in the multivariable analysis. For Asian wait-listed patients with PSC, EV and female gender were the risk factors related to overall survival, and LT was the protective factor. Our experiences suggested that LT brings more benefits in female patients. Strategies are needed to provide equivalent transplant benefits.

Use of Kidneys from Anencephalic Donors to Offset Organ Shortage

Background: It is well recognized that patient survival and quality of life are superior with renal transplantation than with dialysis. Organ availability is far outweighed by the large number of wait-listed patients. Additional stratagems are sought to expand the donor pool, and kidneys from anencephalic infants can be considered a source of organs, until now unexplored. We plan to assess the feasibility of using the kidneys from anencephalic infants for transplantation. Material and Methods: Information about anencephaly, the characteristics of the infant kidneys, the ethical, social and medico-legal aspects raised by the use of these kidneys, their procurement and their transplantation are reviewed. Conclusions: En bloc kidney transplants from infants can provide long-term normal renal function after an accelerated catch up growth. They are not subjected to hyperfiltration since they have a full complement of nephrons. They can be transplanted using the techniques currently available.

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

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. 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. 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]). 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.

The Effect of Model for End-Stage Liver Disease 3.0 on Disparities between Patients with and without Hepatocellular Carcinoma in Korea.

The model for end-stage liver disease (MELD) 3.0 has recently been suggested for determining liver allocation. We aimed to apply MELD 3.0 to a Korean population and to discover differences between patients with and without hepatocellular carcinoma (HCC). This study is a retrospective study of 2203 patients diagnosed with liver cirrhosis at Severance Hospital between 2016-2022. Harrell's concordance index was used to validate the ability of MELD scores to predict 90-day survival. During a mean follow-up of 12.9 months, 90-day survival was 61.9% in all patients, 50.4% in the HCC patients, and 74.8% in the non-HCC patients. Within the HCC patients, the concordance index for patients on the waitlist was 0.653 using MELD, which increased to 0.753 using MELD 3.0. Among waitlisted patients, the 90-day survival of HCC patients was worse than that of non-HCC patients with MELD scores of 31-37 only (69.7% vs. 30.0%, p=0.001). Applying MELD 3.0, the 90-day survival of HCC patients was worse than that of non-HCC patients across a wider range of MELD 3.0 scores, compared to MELD, with MELD 3.0 scores of 21-30 and 31-37 (82.0% vs. 72.5% and 72.3% vs. 24.3%, p=0.02 and p<0.001, respectively). MELD 3.0 predicted 90-day survival of the HCC patients more accurately than original MELD score; however, the disparity between HCC and non-HCC patients increased, particularly in patients with MELD scores of 21-30. Therefore, a novel exception score is needed or the current exception score system should be modified.

Improving equity in kidney transplant allocation policies through a novel genetic metric: The Matched Donor Potential

The demand for donors’ kidneys continues to increase amid a shortage of available donors. Managing policies to thoughtfully allocate this scarce resource is a complex process. Although human leukocyte antigen (HLA) matching has been shown to prolong graft survival, its relative contribution to allocation schemes is empirically compromised owing to competing priorities. We explored using a new metric, Matched Donor Potential (MDP), to facilitate improved HLA matching while promoting equity. We interrogated all active kidney waitlist patients (N = 164 427), their corresponding unacceptable antigen files, and all effective donors in the Scientific Registry of Transplant Recipients (January 1, 2016-December 31, 2017). Cause-specific hazard functions were evaluated to assess the potential impact of the MDP metric on deceased donor transplant access rates for all candidates.Access was affected by ethnicity, blood group type, and calculated Panel Reactive Antibody (cPRA). Importantly, we show that access to transplantation is influenced by the patient’s own HLA makeup regardless of their ethnicity and by the HLA makeup of effective donors. The MDP metric demonstrates a high association with access to transplantation. Adjusting Cox models to include this new metric resulted in improved access to kidney transplantation for waitlist candidates of minority heritage while significantly promoting HLA matching. Thus, the MDP metric accounts for balanced, equitable organ allocation algorithms.

The impact of COVID-19 on liver transplantation: challenges and perspectives.

The coronavirus disease 2019 (COVID-19) pandemic presented unique challenges to patients with decompensated cirrhosis awaiting transplant, with respect to accessing medical facilities for routine clinic visits, imaging, laboratory workup, or endoscopies. There was a delay in organ procurement that led to a decrease in the number of liver transplants (LTs) and an increase in the morality of waitlisted patients at the beginning of the pandemic. LT numbers later equalized to pre-pandemic numbers due to combined efforts and adaptability of transplant centers as well as dynamic guidelines. Due to being immunosuppressed, the demographics of LT patients were at an increased risk of infection. Although there is a higher rate of mortality and morbidity in patients with chronic liver disease, LT itself is not a risk factor for mortality in COVID-19. There was no difference in overall mortality in LT patients compared to non-LT patients, and mortality risk factors were the same: age, hypertension, diabetes, obesity, and chronic kidney disease. The most common causes of death were respiratory complications. Liver-related deaths were reported in 1.6% of patients. The optimal timing of liver transplantation post-infection depends on various factors, such as the severity of liver injury, the presence of comorbidities, and the progression of the underlying liver disease. There is not enough data available on COVID-19 cholangiopathy and the number of cases that will be seen in the future that will require LT. There are some concerns of lower immunogenicity of COVID-19 vaccines in LT patients but available evidence suggests that the vaccines are safe and well-tolerated.

Continuous-flow left ventricular assist devices associated survival awaiting heart and heart-kidney transplant.

Improvement in continuous-flow left ventricular assist device (CF-LVAD) technology has translated to better outcomes for patients on CF-LVAD support as a bridge-to-transplant. However, data are lacking regarding the subset of CF-LVAD patients with renal failure awaiting simultaneous heart-kidney transplant (HKTx). We sought to better understand the characteristics and outcomes of patients in this group. The United Network for Organ Sharing (UNOS) database was used to identify adult patients listed for heart transplant (HTx) or HKTx from January 1, 2009 to March 31, 2017. Patients were followed from time on waitlist to either removal from waitlist or transplantation. Demographic and clinical data for HTx and HKTx patients were assessed. Kaplan-Meier analysis assessed waitlist and post-transplant survival. For waitlisted patients, both death and removal from the waitlist due to deteriorating medical condition were considered events. Overall, 26 638 patients registered for transplant were analyzed. 25 111 (94%) were listed for HTx, and 1527 (6%) for HKTx. 7683 (29%) patients listed for HTx had CF-LVAD support. For those listed for HKTx, 441 (28%) underwent dialysis alone, 256 (17%) had CF-LVAD support alone, and 85 (6%) were treated with both CF-LVAD and dialysis. 15 567 (58%) underwent HTx, and 621 (2%) underwent HKTx. In these groups, post-transplant survival was similar (p=0.06). Patients listed for HKTx treated with both dialysis and CF-LVAD had significantly worse waitlist survival compared to HKTx recipients (p < 0.001). Post-transplant survival is comparable between HTx and HKTx, and early survival is similar between HTx patients and those listed for HTx with CF-LVAD support. However, outcomes on the waitlist for HKTx in CF-LVAD patients on dialysis is significantly worse compared to HKTx recipients. This highlights the need to better account for this patient population when allocating organs.

Anxiety-depression levels and coping strategies among renal transplant waitlisted and non-waitlisted hemodialysis patients

Background/Aim: Although hemodialysis provides prolonged survival, patients face major challenges, including conflicts about life decisions, limited physical, mental, and lifestyle activities, psychological distress, high prevalence of anxiety and depression symptoms, and compromised health-related quality of life. This study aimed to compare anxiety-depression levels and coping strategies between renal transplant waitlisted and non-waitlisted hemodialysis patients. Methods: A total of 75 hemodialysis patients were enrolled in this case-control analytical study, including renal transplant waitlisted (n = 35) and non-waitlisted (n = 40) patients. Patients were asked to fill out a questionnaire including socio-demographic characteristics, duration of hemodialysis, the Hospital Anxiety and Depression Scale, and the Ways of Coping Questionnaire. Comparative analyses were performed via Student's t-test and Pearson Correlation test. Results: The mean age was 57.1 (15.3) years; 56% were males, and being under hemodialysis treatment was 7.3 (5.9) years. Waitlisted and non-waitlisted patients were matched. Overall, 28 patients (37.3%) had anxiety, and 34 patients (45.3%) had depression. There was no significant difference between the two groups regarding depression scores. Anxiety was more common among non-waitlisted than waitlisted patients (P = 0.043). The fatalistic approach was the most common coping strategy applied, and there was a significant negative correlation between anxiety scores and the problem-solving approach (P = 0.034) and a significant positive correlation between depression scores and the helplessness approach (r = 0.234, P = 0.043). Conclusion: Both waitlisted and non-waitlisted hemodialysis patients have significantly higher levels of depression, with anxiety being higher in non-waitlisted patients. Since coping strategies differed concerning anxiety and depression but not transplant candidacy, psychiatric evaluation and counseling would be essential in hemodialysis patients to control the stressors.

BS P04 Global Level of Harm experienced by Bariatric Surgeons for Bariatrics surgical interventions: An exploration of predictors

Abstract Background COVID-19 pandemic has taken the world by surprise with the depth and breadth of its effect on all walks of life, bariatric surgery being no exception. With the scientific literature hitherto unable to comment and ascertain the influence of the COVID-19 pandemic on bariatric surgery and the level of harm experienced by bariatric surgeons, we- TUGS ‘Level of Harm’ collaborative group- attempted to gauge the effect of the said pandemic on bariatrics surgery specifically vis a vis the level of harm experienced by bariatric surgeons due to the pandemic. Methods A virtual questionnaire- developed on both: Google forms and Survey Monkey- was circulated via TUGS social media platforms to reach bariatric consultant surgeons, fellows and residents practising throughout the world in a bid to explore the influence of the COVID-19 pandemic on their surgical practice including but not limited to the annual surgical volume including re-do surgeries volume and postoperative complications. Moreover, they were also requested to categorise their respective level of harm vis a vis bariatric surgical interventions they undertake. After de-identification of the data, SPSS (V.26) was adopted to undergo statistical analysis. After exploring the dataset by descriptive analyses, the Chi-square test was applied to pursue the association of categorical variables with the reported level of harm. A double-sided p-value of less than 0.05 was considered statistically significant. Results 16.8% of the respondents (21/125) indicated no harm vis a vis bariatrics surgery work whereas a comparative 18.4% of the respondents (23/125) reported moderate harm with significant worsening of symptoms. None of those who indicated less than 10% increase in surgery waitlisted patients being subjected to endoscopic interventions (0/14) reported Moderate Harm for bariatrics surgery work with significant worsening of symptoms whereas 1 in every 3 of those who indicated between 10% to 25% increase in surgery waitlisted patients being subjected to endoscopic interventions (5/15) reported such level of harm for bariatrics surgery work. (p &amp;lt; 0.001) Upon exhaustive sub-group analysis, it was uncovered that 33.6% of bariatrics surgical professionals perceived no harm (no evidence of change in clinical condition) during gastric band or related surgery work with only 4% perceiving Moderate Harm (significant worsening of symptoms/ comorbidities control/ minor increase in medications) for such surgical interventions. All of those who reported No harm for gastric band or related surgical work reported that Single anastomosis duodeno–ileal bypass (SADI-S) accounts for 10% of their practice whereas none of those who indicated that SADI-S accounts for more than 10% of their practice reported No harm for such surgical work. (p = 0.019) Conclusions The global snapshot illustrates a trend of low harm vis a vis bariatrics surgery work in surgical professionals practising in the private sector with a lesser number of patients developing COVID-19 postoperatively and no postoperative COVID-19 related mortality. The patient being subjected to endoscopic intervention portends a higher level of harm for bariatrics surgical work- strict adherence to criteria and safety protocols being a logical inference. For gastric band and related surgery work, preoperative COVID-19 testing appears to be influenced by confounders in its effect on the surgeon's level of harm for the said interventions warranting further exploration. SADI-S, at a cut-off of 10%, exhibits strong interaction with the surgeon's level of harm for gastric band insertion and relation surgery work. Women surgical professionals came out to exhibit equivalent mental resilience and technical prowess at par with their male colleagues when it came to bariatrics surgical intervention.

WAITING LIST FOR LIVER TRANSPLANTATION: CLINICAL AND ECONOMIC BURDEN.

Burden of disease is an indicator that relates to health status. United States and European epidemiological data have shown that the burden of chronic liver disease has increased significantly in recent decades. There are no studies evaluating the impact of complications of chronic liver disease on the waiting list for deceased donor liver transplantation (LTx). To determine the clinical and economic burden of complications of liver disease in wait-listed patients from the perspective of a transplant center. The study retrospectively analyzed medical records of 104 patients wait-listed for deceased donor LTx from October 2012 to May 2016 and whose treatment was fully provided at the study transplant center. Clinical data were obtained from electronic medical records, while economic data were collected from a hospital management software. To allocate all direct medical costs, two methods were used: full absorption costing and micro-costing. The most common complication was refractory ascites (20.2%), followed by portosystemic encephalopathy (12.5%). The mean number of admissions per patient was 1.37±3.42. Variceal hemorrhage was the complication with longest median length of stay (18 days), followed by hepatorenal syndrome (13.5 days). Hepatorenal syndrome was the costliest complication (mean cost of $3,565), followed by portosystemic encephalopathy ($2,576) and variceal hemorrhage ($1,530). The burden of chronic liver disease includes a great cost for health systems. In addition, it is likely to be even greater as a result of the insidious course of the disease.

The impact of COVID-19 on liver transplantation programs in Austria.

Coronavirus disease of 2019 (COVID-19) has affected liver disease management. The impact of the COVID-19 pandemic on the Austrian orthotopic liver transplantation (OLT) programs, however, has not been systematically investigated. All patients listed for OLT in Austria during 2020-2021 were studied. Data on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) testing, vaccinations, infections, mortality and the overall number of OLTs (vs. pre-COVID-19: 2015-2019) were analyzed. Overall, 490patients (median age: 58.0years, 70.4% men, hepatocellular carcinoma: 27.3%) were listed for OLT in Austria in 2020-2021. Alcohol-related cirrhosis (35.3%), cholestatic (16.7%) and viral liver disease (13.9%) were the main etiologies. Of the patients 61.2% underwent OLT and 8.8% died while on the waiting list. The number of OLTs performed during COVID-19 (2020: n = 150; 2021: n = 150) remained unchanged compared to pre-COVID-19 (median: n = 152). Among waiting list patients, 7.7% (n = 31/401) were diagnosed with COVID-19 and 7 (22.6%) of these patients died. By the end of 2021, 45.1% (n = 176/390; 82.8% mRNA vaccinations) and 28.8% (105/365) of patients received 2 and 3 SARS-CoV‑2 vaccinations, respectively. After two SARS-CoV‑2 vaccinations, antibodies more often remained undetectable in patients vaccinated post-OLT (25.6% vs. 6.5% in patients vaccinated pre-OLT; p = 0.034). Patients with three vaccinations after OLT had lower antibody titers than patients vaccinated pre-OLT (post-OLT: 513.5, IQR 44.4-2500.0 vs. pre-OLT: 2500.0, IQR 1462.0-2500.0 BAU/mL; p = 0.020). The number of OLTs in Austria remained unchanged during COVID-19. SARS-CoV‑2 infections were rare but associated with high mortality in patients on the Austrian OLT waiting lists. SARS-CoV‑2 vaccination rates at the end of 2021 were suboptimal, while serological response was better in patients vaccinated pre-OLT vs. post-OLT.

Abstract 11846: Factors Influencing Survival in Adult Patients With Congenital Heart Disease Considered for Transplant: A Single Center Study

Introduction: Adult congenital heart disease (ACHD) patients pose unique challenges in identifying time for transplantation and factors influencing outcomes. Hypothesis: Survival outcomes in ACHD patients depend on hemodynamic, functional, and laboratory parameters. Methods: We performed a retrospective chart review of adult patients (&gt;18y) with CHD evaluated for heart or heart+ transplant between November 2004 and July 2014 and evaluated outcomes until December 2020 at University of Pittsburgh Medical Center. Multiple clinical parameters were evaluated to identify factors influencing outcomes for up to 10 years after consideration for transplant. Kruskal-Wallis nonparametric analysis was conducted to compare differences between variables. Results: 58 adult patients with congenital heart disease (CHD), age range 20-55 years were evaluated. D-TGA with atrial switch operation (20.7%), tetralogy of Fallot/pulmonary atresia (15.5%) and tricuspid atresia (13.8%) were the most common diagnosis for transplant. Of the 58 patients, 5 (8.6%) were deferred, 42 (72.4%) were listed for transplant and 11 (18.9%) were declined for transplant. Statistically significant factors affecting listing decision are included in table 1. Declined patients showed the highest 1-year mortality (18.2%), whereas waitlisted patients showed the highest 10-year mortality (84.2%). In the post-transplantation period, 30 day survival was 87.0%, 1-yr was 82.6%, and 5-yr and 10 year was 69.6%. 1-year post-transplant survival was influenced by pre-transplant end diastolic pressures, use of advanced life support, and right atrial pressure. There was no significant difference in post-transplant survival between single ventricle versus bi-ventricular patients. Conclusions: We have identified clinical factors that influence survival outcomes in ACHD patients considered for transplantation, These can applied while making transplant decisions and improve outcomes

Diagnostic Yield Among Patients With Diabetic Nephropathy and/or Hypertension: Genetic Testing in Kidney Transplant Waitlist Patients

Diagnostic Yield Among Patients With Diabetic Nephropathy and/or Hypertension: Genetic Testing in Kidney Transplant Waitlist Patients

An ex-ante cost-utility analysis of the deemed consent legislation compared to expressed consent for kidney transplantations in Nova Scotia

BackgroundThis study was an ex-ante cost-utility analysis of deemed consent legislation for deceased organ donation in Nova Scotia, a province in Canada. The legislation became effective in January 2021. The study's objective was to assess the conditions necessary for the legislation change’s cost-effectiveness compared to expressed consent, focusing on kidney transplantation (KT).MethodWe performed a cost-utility analysis using a Markov model with a lifetime horizon. The study was from a Canadian payer perspective. The target population was patients with end-stage kidney disease (ESKD) in Atlantic Canada waitlisted for KT. The intervention was the deemed consent and accompanying health system transformations. Expressed consent (before the change) was the comparator. We simulated the minimum required increase in deceased donor KT per year for the cost-effectiveness of the deemed consent. We also evaluated how changes in dialysis and maintenance immunosuppressant drug costs and living donor KT per year impacted cost-effectiveness in sensitivity analyses.ResultsThe expected lifetime cost of an ESKD patient ranged from $177,663 to $553,897. In the deemed consent environment, the expected lifetime cost per patient depended on the percentage increases in the proportion of ESKD patients on the waitlist getting a KT in a year. The incremental cost-utility ratio (ICUR) increased with deceased donor KT per year. Cost-effectiveness of deemed consent compared to expressed consent required a minimum of a 1% increase in deceased donor KT per year. A 1% increase was associated with an ICUR of $32,629 per QALY (95% CI: − $64,279, $232,488) with a 81% probability of being cost-effective if the willingness-to-pay (WTP) was $61,466. Increases in dialysis and post-KT maintenance immunosuppressant drug costs above a threshold impacted value for money. The threshold for immunosuppressant drug costs also depended on the percent increases in deceased donor KT probability and the WTP threshold.ConclusionsThe deemed consent legislation in NS for deceased organ donation and the accompanying health system transformations are cost-effective to the extent that they are anticipated to contribute to more deceased donor KTs than before, and even a small increase in the proportion of waitlist patients receiving a deceased donor KT than before the change represents value for money.

S1237 Association of Liver Biopsy Pathology on Outcome of Patients Undergoing Heart Transplantation

Introduction: Patients with advanced heart failure needing heart transplant (HT) commonly have some degree of liver dysfunction. Liver biopsies are the gold-standard for evaluating the severity of liver disease and are commonly performed prior to listing a patient for HT. However, there is limited data on the impact of liver fibrosis on outcomes for HT candidates. The objective of this study was to determine the relationship between liver fibrosis severity and mortality rates for patients on the HT waitlist and post-HT. Methods: A retrospective cohort study of adults listed for HT who underwent a liver biopsy for evaluation of liver fibrosis from 08/12/2004-02/16/2022 at a large heart transplant center was performed. Degree of fibrosis was categorized as either early (only fibrosis expansion of portal areas with or without short fibrous septa or no fibrosis) or advanced (evidence of portal-to-portal bridging or cirrhosis). Trend analysis was performed on clinical, laboratory and mortality data using Cox proportional hazard model, controlling for MELD-XI. At-risk period starts at the time of waitlist and extends into the post-transplant phase. The end of the follow-up period was defined as mortality on the waitlist, mortality post-HT, or administrative censoring at the end of the study period. Results: Of 42 patients with liver biopsies, 14 (33%) had advanced fibrosis, 28 (67%) had early fibrosis, and 2 (5%) patients had cirrhosis. There was no significant difference in the survival of patients with advanced fibrosis and early fibrosis over time (HR 1.37, CI 0.47- 3.98, p = 0.56). Fifteen waitlisted patients did not eventually receive transplants, and there was no significant difference in survival within group (HR 0.65, CI 0.18-2.32, p = 0.51); 9 of these 15 patients died on the waitlist. Twenty-seven patients did eventually receive transplants, and there was no significant difference in survival within this group (HR 1.00, CI 0.09-11.43, p = 1.00). (Figure) Conclusion: There was no significant difference in the survival rates between HT candidates with and without advanced fibrosis on the waitlist and post-HT, suggesting that patients on the transplant waitlist may not need liver biopsy for heart transplant workup. However, our sample population was derived from patients who were already on the transplant waitlist. Therefore, our results cannot be extrapolated to the general advanced heart failure population undergoing HT evaluation, many of whom are not waitlisted due to cirrhosis (Table).

The impact of deprivation on patients awaiting planned care.

Deprivation underpins many societal and health inequalities. COVID-19 has exacerbated these disparities, with access to planned care falling greatest in the most deprived areas of the UK during 2020. This study aimed to identify the impact of deprivation on patients on growing waiting lists for planned care. Questionnaires were sent to orthopaedic waiting list patients at the start of the UK's first COVID-19 lockdown to capture key quantitative and qualitative aspects of patients' health. A total of 888 respondents were divided into quintiles, with sampling stratified based on the Index of Multiple Deprivation (IMD); level 1 represented the 'most deprived' cohort and level 5 the 'least deprived'. The least deprived cohort were older (mean 65.95 years (SD 13.33)) than the most deprived (mean 59.48 years (SD 13.85)). Mean symptom duration was lower in the least deprived areas (68.59 months (SD 112.26)) compared to the most deprived (85.85 months (SD 122.50)). Mean pain visual analogue scores (VAS) were poorer in the most compared to the least deprived cohort (7.11 (SD 2.01) vs 5.99 (SD 2.57)), with mean mood scores also poorer (6.06 (SD 2.65) vs 4.71 (SD 2.78)). The most deprived areas exhibited lower mean quality of life (QoL) scores than the least (0.37 (SD 0.30) vs 0.53 (SD 0.31)). QoL findings correlated with health VAS and Generalized Anxiety Disorder 2-item (GAD2) scores, with the most deprived areas experiencing poorer health (health VAS 50.82 (SD 26.42) vs 57.29 (SD 24.19); GAD2: 2.94 (SD 2.35) vs 1.88 (SD 2.07)). Least-deprived patients had the highest self-reported activity levels and lowest sedentary cohort, with the converse true for patients from the most deprived areas. The most deprived patients experience poorer physical and mental health, with this most adversely impacted by lengthy waiting list delays. Interventions to address inequalities should focus on prioritizing the most deprived.Cite this article: Bone Jt Open2022;3(10):777-785.
