Organizational and Implementation Factors Associated with Cirrhosis Care in the Veterans Health Administration. Dig Dis Sci 2024:10.1007/s10620-024-08409-6. [PMID: 38616215 DOI: 10.1007/s10620-024-08409-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Accepted: 03/25/2024] [Indexed: 04/16/2024]
Abstract
BACKGROUND The Veterans Health Administration provides care to more than 100,000 Veterans with cirrhosis. AIMS This implementation evaluation aimed to understand organizational resources and barriers associated with cirrhosis care. METHODS Clinicians across 145 Department of Veterans Affairs (VA) medical centers (VAMCs) were surveyed in 2022 about implementing guideline-concordant cirrhosis care. VA Corporate Data Warehouse data were used to assess VAMC performance on two national cirrhosis quality measures: HCC surveillance and esophageal variceal surveillance or treatment (EVST). Organizational factors associated with higher performance were identified using linear regression models. RESULTS Responding VAMCs (n = 124, 86%) ranged in resource availability, perceived barriers, and care processes. In multivariable models, factors independently associated with HCC surveillance included on-site interventional radiology and identifying patients overdue for surveillance using a national cirrhosis population management tool ("dashboard"). EVST was significantly associated with dashboard use and on-site gastroenterology services. For larger VAMCs, the average HCC surveillance rate was similar between VAMCs using vs. not using the dashboard (47% vs. 41%), while for smaller and less resourced VAMCs, dashboard use resulted in a 13% rate difference (46% vs. 33%). Likewise, higher EVST rates were more strongly associated with dashboard use in smaller (55% vs. 50%) compared to larger (57% vs. 55%) VAMCs. CONCLUSIONS Resources, barriers, and care processes varied across diverse VAMCs. Smaller VAMCs without specialty care achieved HCC and EVST surveillance rates nearly as high as more complex and resourced VAMCs if they used a population management tool to identify the patients due for cirrhosis care.

Refractory hepatic hydrothorax is associated with increased mortality with death occurring at lower MELD-Na compared to cirrhosis and refractory ascites. Hepatology 2024; 79:844-856. [PMID: 37625139 DOI: 10.1097/hep.0000000000000577] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/04/2023] [Accepted: 08/15/2023] [Indexed: 08/27/2023]
Abstract
BACKGROUND AND AIMS Although refractory hepatic hydrothorax (RH) is a serious complication of cirrhosis, waitlisted patients do not receive standardized Model for End-stage Liver Disease (MELD) exemption because of inadequate evidence suggesting mortality above biochemical MELD. This study aimed to examine liver-related death (LRD) associated with RH compared to refractory ascites (RA). APPROACH AND RESULTS This was a retrospective cohort study of Veterans with cirrhosis. Eligibility criteria included participants with RH or RA, followed from their first therapeutic thoracentesis/second paracentesis until death or transplantation. The primary outcome was LRD with non-LRD or transplantation as competing risk. Of 2552 patients with cirrhosis who underwent therapeutic thoracentesis/paracentesis, 177 met criteria for RH and 422 for RA. RH was associated with a significantly higher risk of LRD (adjusted HR [aHR] 4.63, 95% CI 3.31-6.48) than RA overall and within all MELD-sodium (MELD-Na) strata (<10 aHR 4.08, 95% CI 2.30-7.24, 10-14.9 aHR 5.68, 95% CI 2.63-12.28, 15-24.9 aHR 4.14, 95% CI 2.34-7.34, ≥25 aHR 7.75, 95% CI 2.99-20.12). LRD was higher among participants requiring 1 (aHR 3.54, 95% CI 2.29-5.48), 2-3 (aHR 4.39, 95% CI 2.91-6.63), and ≥4 (aHR 7.89, 95% CI 4.82-12.93) thoracenteses relative to RA. Although participants with RH and RA had similar baseline MELD-Na, LRD occurred in RH versus RA at a lower MELD-Na (16.5 vs. 21.82, p =0.002) but higher MELD 3.0 (27.85 vs. 22.48, p <0.0001). CONCLUSIONS RH was associated with higher risk of LRD than RA at equivalent MELD-Na. By contrast, MELD 3.0 may better predict risk of LRD in RH.

Liver Stiffness Measurement and Risk Prediction of Hepatocellular Carcinoma After HCV Eradication in Veterans With Cirrhosis. Clin Gastroenterol Hepatol 2024; 22:778-788.e7. [PMID: 38061410 PMCID: PMC10960676 DOI: 10.1016/j.cgh.2023.11.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Revised: 11/05/2023] [Accepted: 11/17/2023] [Indexed: 01/04/2024]
Abstract
BACKGROUND & AIMS Patients with cirrhosis secondary to chronic hepatitis C virus (HCV) are at risk for hepatocellular carcinoma (HCC) despite a sustained virological response (SVR). We examined whether post-SVR liver stiffness measurement (LSM) could be used to stratify HCC risk. METHODS This was a retrospective cohort study of 1850 participants identified from the Veterans Health Administration, with HCV cirrhosis and SVR, followed up over 5099 person-years, from the time of post-SVR elastography until death, HCC, or the end of the study. RESULTS The risk of HCC increased by 3% with every 1-kPa increase in LSM (adjusted hazard ratio [aHR], 1.03, 95% confidence interval [CI], 1.01-1.04; P < .001) and decreased with the number of years from SVR (aHR, 0.79; 95% CI, 0.70-0.90; P = .0003). The adjusted annual risk of HCC was 2.03% among participants with post-SVR LSM <10 kPa, 2.48% in LSM 10-14.9 kPa (aHR, 1.71; 95% CI, 1.01-2.88; P = .046), 3.22% for LSM 15-19.9 kPa (aHR, 1.59; 95% CI, 0.78-3.20; P = .20), 5.07% among LSM 20-24.9 kPa (aHR, 2.55; 95% CI, 1.30-5.01; P = .01), and 5.44% in LSM ≥25 kPa (aHR, 3.03; 95% CI, 1.74-5.26; P < .0001). The adjusted annual risk of HCC was < 0.4% in participants with LSM <5 kPa and without diabetes mellitus. CONCLUSIONS LSM predicts rates of HCC in patients with HCV cirrhosis after SVR at multiple cutoff levels and offers a single test to predict portal hypertension-related complications and HCC. Patients with LSM <5 kPa in the absence of diabetes mellitus had a low risk of HCC in which surveillance could be discontinued.

Systemic Therapy for Advanced Hepatocellular Carcinoma: ASCO Guideline Update. J Clin Oncol 2024:JCO2302745. [PMID: 38502889 DOI: 10.1200/jco.23.02745] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2023] [Accepted: 12/28/2023] [Indexed: 03/21/2024] Open
Abstract
PURPOSE To update an evidence-based guideline to assist in clinical decision-making for patients with advanced hepatocellular carcinoma (HCC). METHODS ASCO convened an Expert Panel to update the 2020 guideline on systemic therapy for HCC. The panel updated the systematic review to include randomized controlled trials (RCTs) published through October 2023 and updated recommendations. RESULTS Ten new RCTs met the inclusion criteria and were added to the evidence base. RECOMMENDATIONS Atezolizumab + bevacizumab (atezo + bev) or durvalumab + tremelimumab (durva + treme) may be offered first-line for patients with advanced HCC, Child-Pugh class A liver disease, and Eastern Cooperative Oncology Group performance status 0-1. Where there are contraindications to these therapies, sorafenib, lenvatinib, or durvalumab may be offered first-line. Following first-line treatment with atezo + bev, second-line therapy with a tyrosine kinase inhibitor (TKI), ramucirumab (for patients with alpha-fetoprotein [AFP] ≥400 ng/mL), durva + treme, or nivolumab + ipilimumab (nivo + ipi) may be recommended for appropriate candidates. Following first-line therapy with durva + treme, second-line therapy with a TKI is recommended. Following first-line treatment with sorafenib or lenvatinib, second-line therapy options include cabozantinib, regorafenib for patients who previously tolerated sorafenib, ramucirumab (AFP ≥400 ng/mL), nivo + ipi, or durvalumab; atezo + bev or durva + treme may be considered for patients who did not have access to these therapies in the first-line setting, and do not have contraindications. Pembrolizumab or nivolumab are also options for appropriate patients following sorafenib or lenvatinib. Third-line therapy may be considered in Child-Pugh class A patients with good PS, using one of the agents listed previously that has a nonidentical mechanism of action with previously received therapy. A cautious approach to systemic therapy is recommended for patients with Child-Pugh class B advanced HCC. Further guidance on choosing between options is included within the guideline.Additional information is available at www.asco.org/gastrointestinal-cancer-guidelines.

Accuracy of blood-based biomarkers for staging liver fibrosis in chronic liver disease: A systematic review supporting the AASLD Practice Guideline. Hepatology 2024:01515467-990000000-00805. [PMID: 38489517 DOI: 10.1097/hep.0000000000000842] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Accepted: 02/19/2024] [Indexed: 03/17/2024]
Abstract
BACKGROUND AND AIMS Blood-based biomarkers have been proposed as an alternative to liver biopsy for non-invasive liver disease assessment (NILDA) in chronic liver disease (CLD). Our aims for this systematic review were to evaluate the diagnostic utility of selected blood-based tests either alone, or in combination, for identifying significant fibrosis (F2-4), advanced fibrosis (F3-4) and cirrhosis (F4), as compared to biopsy in CLD. APPROACH AND RESULTS We included a comprehensive search of databases including Ovid MEDLINE(R), EMBASE, Cochrane Database, and Scopus through to April 2022. Two independent reviewers selected 286 studies with 103,162 patients. The most frequently identified studies included the simple aminotransferase-to-platelet ratio index (APRI) and fibrosis (FIB)-4 markers (with low-to-moderate risk of bias) in hepatitis B virus (HBV) and C virus (HCV), HIV-HCV/HBV co-infection, and nonalcoholic fatty liver disease (NAFLD). Positive (LR+) and negative (LR) likelihood ratios across direct and indirect biomarker tests for HCV and HBV for F2-4, F3-4, or F4 were 1.66-6.25 and 0.23-0.80, 1.89-5.24 and 0.12-0.64, and 1.32-7.15 and 0.15-0.86 respectively; LR+ and LR for NAFLD F2-4, F3-4 and F4 were 2-65-3.37 and 0.37-0.39, 2.25-6.76 and 0.07-0.87, and 3.90 and 0.15 respectively. Overall, proportional odds ratio indicated FIB-4 <1.45 was better than APRI <0.5 for F2-4. FIB-4 >3.25 was also better than APRI >1.5 for F3-4 and F4. There was limited data for combined tests. CONCLUSIONS Blood-based biomarkers are associated with small-to-moderate change in pre-test probability for diagnosing F2-4, F3-4, and F4 in viral hepatitis, HIV-HCV co-infection, and NAFLD, with limited comparative or combination studies for other CLD.

Abstract
OBJECTIVES Clinical text processing offers a promising avenue for improving multiple aspects of healthcare, though operational deployment remains a substantial challenge. This case report details the implementation of a national clinical text processing infrastructure within the Department of Veterans Affairs (VA). METHODS Two foundational use cases, cancer case management and suicide and overdose prevention, illustrate how text processing can be practically implemented at scale for diverse clinical applications using shared services. RESULTS Insights from these use cases underline both commonalities and differences, providing a replicable model for future text processing applications. CONCLUSIONS This project enables more efficient initiation, testing, and future deployment of text processing models, streamlining the integration of these use cases into healthcare operations. This project implementation is in a large integrated health delivery system in the United States, but we expect the lessons learned to be relevant to any health system, including smaller local and regional health systems in the United States.

Community-Level Factors Associated with Hepatocellular Carcinoma Incidence and Mortality: An Observational Registry Study. Cancer Epidemiol Biomarkers Prev 2024; 33:270-278. [PMID: 38059831 PMCID: PMC10872555 DOI: 10.1158/1055-9965.epi-23-0902] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2023] [Revised: 10/23/2023] [Accepted: 12/05/2023] [Indexed: 12/08/2023] Open
Abstract
BACKGROUND Hepatocellular carcinoma (HCC) incidence and outcomes vary across populations in the United States, but few studies evaluate local drivers of observed disparities. We measured HCC incidence at the community level and assessed community-level HCC risk factors with the goal of informing resource allocation to improve early case detection, which is associated with improved outcomes. METHODS Clinical and demographic data including census tract of residence for all adults diagnosed with HCC in the Connecticut Tumor Registry between 2008 and 2019 were combined with publicly available U.S. Census and Centers for Disease Control and Prevention (CDC) data at the ZIP Code tabulation area (ZCTA) level. The average annual incidence of HCC was calculated for each ZCTA and associations between community-level characteristics, HCC incidence, stage at diagnosis, and survival were evaluated. RESULTS Average annual HCC incidence during the study period was 8.9/100,000 adults and varied from 0 to 97.7 per 100,000 adults by ZCTA. At the community level, lower rates of high school graduation, higher rates of poverty, and rural community type were associated with higher HCC incidence. Persons with HCC living in the highest incidence ZCTAs were diagnosed at a younger age and were less likely to be alive at 1, 2, and 5 years after diagnosis. CONCLUSIONS Community-level socioeconomic factors are strongly associated with HCC incidence and survival in Connecticut. IMPACT This reproducible geo-localization approach using cancer registry, Census, and CDC data can be used to identify communities most likely to benefit from health system investments to reduce disparities in HCC.

The Association Between Homelessness and Key Liver-Related Outcomes in Veterans With Cirrhosis. Am J Gastroenterol 2024; 119:297-305. [PMID: 37782293 DOI: 10.14309/ajg.0000000000002535] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Accepted: 09/06/2023] [Indexed: 10/03/2023]
Abstract
INTRODUCTION Homelessness adversely affects patient outcomes in broad cohort studies; however, its impact on key liver-related outcomes in patients with cirrhosis is understudied. We aimed to address this knowledge gap using data from the Veterans Health Administration, a cohort disproportionately affected by homelessness. METHODS This was a retrospective cohort study of the Veterans Health Administration patients with incident cirrhosis diagnosis between January 2008 and February 2022. Homeless status was classified at baseline and as time-updating variable during follow-up. Inverse probability treatment weighted Cox regression was performed to evaluate the association between homelessness and outcomes of all-cause mortality, cirrhosis decompensation, and hepatocellular carcinoma. RESULTS A total of 117,698 patients were included in the cohort, of whom 14,243 (12.1%) were homeless at baseline. In inverse probability treatment weighted Cox regression, homelessness was associated with a 24% higher hazard of all-cause mortality (hazard ratio [HR] 1.24, 95% confidence interval [CI] 1.22-1.26, P < 0.001). However, in competing risk regression models, homelessness was associated with a reduced subhazard of decompensation (subhazard ratio 0.86, 95% CI 0.84-0.88, P < 0.001) and hepatocellular carcinoma (subhazard ratio 0.86, 95% CI 0.83-0.89, P < 0.001). In cause-specific mortality analysis, homeless patients had significantly increased non-liver-related and liver-related mortality; however, the magnitude of effect size was greater for non-liver-related mortality (csHR 1.38, 95% CI 1.35-1.40, P < 0.001). DISCUSSION Homelessness in veterans with cirrhosis is associated with increased all-cause mortality; however, this is likely mediated primarily through non-liver-related factors. Future studies are needed to explore drivers of mortality and improve mitigation strategies in these patients.

Abstract
BACKGROUND & AIMS The coronavirus disease-2019 pandemic profoundly disrupted preventative health care services including cancer screening. As the largest provider of cirrhosis care in the United States, the Department of Veterans Affairs (VA) National Gastroenterology and Hepatology Program aimed to assess factors associated with hepatocellular carcinoma (HCC) stage at diagnosis, treatment, and survival. METHODS Veterans with a new diagnosis of HCC in 2021 were identified from electronic health records (N = 2306). Structured medical record extraction was performed by expert reviewers in a 10% random subsample of Veterans with new HCC diagnoses. Factors associated with stage at diagnosis, receipt of treatment, and survival were assessed using multivariable models. RESULTS Among 199 patients with confirmed HCC, the average age was 71 years and most (72%) had underlying cirrhosis. More than half (54%) were at an early stage (T1 or T2) at diagnosis. Less-advanced liver disease, number of imaging tests adequate for HCC screening, HCC diagnosis in the VA, and receipt of VA primary care were associated significantly with early stage diagnosis. HCC-directed treatments were administered to 145 (73%) patients after a median of 37 days (interquartile range, 19-54 d) from diagnosis, including 70 (35%) patients who received potentially curative treatments. Factors associated with potentially curative (vs no) treatments included HCC screening, early stage at diagnosis, and better performance status. Having fewer comorbidities and better performance status were associated significantly with noncurative (vs no) treatment. Early stage diagnosis, diagnosis in the VA system, and receipt of curative treatment were associated significantly with survival. CONCLUSIONS These results highlight the importance of HCC screening and engagement in care for HCC diagnosis, treatment, and survival while demonstrating the feasibility of developing a national quality improvement agenda for HCC screening, diagnosis, and treatment.

Abstract
BACKGROUND Diabetes is associated with HCC; however, the impact of longitudinal blood glucose (BG) control on HCC risk in cirrhosis is not well known. We investigated this knowledge gap in a cohort of United States Veterans with cirrhosis from 2015 to 2021. METHODS We used repeated hemoglobin A1c measurements to categorize follow-up time according to BG control (defined as hemoglobin A1c < 7%) state over time: uncontrolled, nonsustained control (≤2 y), or sustained control (>2 y). We performed a sensitivity analysis using hemoglobin A1c < 8% to define BG control. We used Fine and Gray Cox proportional hazards regression with death and transplant as competing events to compare rates of incident HCC. RESULTS Our study included 81,907 individuals, 56.2% of whom had diabetes at baseline. There were 8,002 incident HCCs. The rate of HCC was 18% higher in diabetes (95% CI: 13% - 24%), and the relative increase in the rate of HCC varied by etiology of cirrhosis from nonsignificant (HCV) to an increase of 120% (HBV). Uncontrolled and nonsustained BG control was associated with 1.80 (95% CI: 1.70-1.91) and 2.34 (95% CI: 2.21-2.48) times the rate of HCC compared to sustained BG control, respectively. Using Hgb A1c < 8% to define BG control, HCC rates in uncontrolled and nonsustained BG control were 2.43 (2.28-2.58) and 2.23 (2.11-2.36) times that observed in sustained BG control. CONCLUSIONS Associations between diabetes and HCC in cirrhosis vary according to the longitudinal BG control state. Inadequate BG control is consistently associated with a higher risk of HCC, and long-term BG control should be considered in comprehensive cirrhosis care.

Performance of an automated deep learning algorithm to identify hepatic steatosis within noncontrast computed tomography scans among people with and without HIV. Pharmacoepidemiol Drug Saf 2023; 32:1121-1130.

Abstract
PURPOSE Hepatic steatosis (fatty liver disease) affects 25% of the world's population, particularly people with HIV (PWH). Pharmacoepidemiologic studies to identify medications associated with steatosis have not been conducted because methods to evaluate liver fat within digitized images have not been developed. We determined the accuracy of a deep learning algorithm (automatic liver attenuation region-of-interest-based measurement [ALARM]) to identify steatosis within clinically obtained noncontrast abdominal CT images compared to manual radiologist review and evaluated its performance by HIV status. METHODS We performed a cross-sectional study to evaluate the performance of ALARM within noncontrast abdominal CT images from a sample of patients with and without HIV in the US Veterans Health Administration. We evaluated the ability of ALARM to identify moderate-to-severe hepatic steatosis, defined by mean absolute liver attenuation <40 Hounsfield units (HU), compared to manual radiologist assessment. RESULTS Among 120 patients (51 PWH) who underwent noncontrast abdominal CT, moderate-to-severe hepatic steatosis was identified in 15 (12.5%) persons via ALARM and 12 (10%) by radiologist assessment. Percent agreement between ALARM and radiologist assessment of absolute liver attenuation <40 HU was 95.8%. Sensitivity, specificity, positive predictive value, and negative predictive value of ALARM were 91.7% (95%CI, 51.5%-99.8%), 96.3% (95%CI, 90.8%-99.0%), 73.3% (95%CI, 44.9%-92.2%), and 99.0% (95%CI, 94.8%-100%), respectively. No differences in performance were observed by HIV status. CONCLUSIONS ALARM demonstrated excellent accuracy for moderate-to-severe hepatic steatosis regardless of HIV status. Application of ALARM to radiographic repositories could facilitate real-world studies to evaluate medications associated with steatosis and assess differences by HIV status.

Multidisciplinary teams, efficient communication, procedure services, and telehealth improve cirrhosis care: A qualitative study. Hepatol Commun 2023; 7:e0157. [PMID: 37219845 PMCID: PMC10208700 DOI: 10.1097/hc9.0000000000000157] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Accepted: 03/29/2023] [Indexed: 05/24/2023] Open
Abstract
BACKGROUND Cirrhosis care and outcomes are improved with access to subspecialty gastroenterology and hepatology care. In qualitative interviews, we investigated clinicians' perceptions of factors that optimize or impede cirrhosis care. METHODS We conducted 24 telephone interviews with subspecialty clinicians at 7 Veterans Affairs medical centers with high- and low-complexity services. Purposive sampling stratified Veterans Affairs medical centers on timely post-hospitalization follow-up, a quality measure. We asked open-ended questions about facilitators and barriers of care coordination, access to appointments, procedures, transplantation, management of complications, keeping up to date with medical knowledge, and telehealth use. RESULTS Key themes that facilitated care were structural: multidisciplinary teams, clinical dashboards, mechanisms for appointment tracking and reminders, and local or virtual access to transplant and liver cancer specialists through the "specialty care access network extension for community health care outcomes" program. Coordination and efficient communication between transplant and non-transplant specialists and between transplant and primary care facilitated timely care. Same-day access to laboratory, procedural, and clinical services is an indicator of high-quality care. Barriers included lack of on-site procedural services, clinician turnover, patient social needs related to transportation, costs, and patient forgetfulness due to HE. Telehealth enabled lower complexity sites to obtain recommendations for complex patient cases. Barriers to telehealth included lack of credit (eg, VA billing equivalent), inadequate staff, lack of audiovisual technology support, and patient and staff discomfort with technology. Telehealth was optimal for return visits, cases where physical examination was nonessential, and where distance and transportation precluded in-person care. Rapid telehealth uptake during the COVID-19 pandemic was a positive disruptor and facilitated use. CONCLUSIONS We identify multi-level factors related to structure, staffing, technology, and care organization to optimize cirrhosis care delivery.

Using Telemedicine to Facilitate Patient Communication and Treatment Decision-Making Following Multidisciplinary Tumor Board Review for Patients with Hepatocellular Carcinoma. J Gastrointest Cancer 2023; 54:623-631.

Abstract
BACKGROUND AND AIMS A rapid increase in the use of telemedicine for delivering healthcare has occurred since the onset of the Covid-19 pandemic. There is evidence for using telemedicine to facilitate cancer care delivery for patients with hepatocellular carcinoma (HCC). Examining how telemedicine can be used to communicate multidisciplinary tumor board (MTB) recommendations for HCC has not been studied. This study has two specific aims: (1) to evaluate the patient perspective of the MTB review process and identify best strategies for communicating treatment recommendations for HCC and (2) to pilot test a telemedicine intervention following MTB review to assess patient feasibility and satisfaction with using telemedicine to facilitate treatment decision-making and treatment referral. METHODS We conducted a mixed-methods study. First, semi-structured qualitative interviews were conducted among patients diagnosed with HCC who were discussed in MTB review at one of three VA Medical Centers (VAMC). We collected information about the MTB process from the patient perspective and identified strategies for improving communication and delivery of care. Rapid qualitative analysis was used to inform intervention development. Using our qualitative data, a MTB telemedicine pilot intervention was developed and implemented to assess the feasibility of using this approach for patients with HCC. RESULTS Almost all patients (94%) in the pilot study would recommend telemedicine to other patients with HCC, and half of the patients (50%) preferred telemedicine over in-person visits. Many patients (81%) found communication through telemedicine an acceptable platform to deliver difficult cancer information. Overall, patients felt they understood their treatment recommendations and found them clear and useful. Further, patients reported that they enjoyed being included in the decision-making process and appreciated being able to have family members easily join them for the telemedicine visit. CONCLUSIONS Using telemedicine to communicate treatment recommendations following MTB review was found to be feasible and an acceptable alternative to an in-person visit for patient with HCC. Future studies could include expanding this approach for communicating MTB recommendations to patients with other types of cancers.

Adherence to Tumor Board Recommendations in the Treatment of Patients with Hepatocellular Carcinoma. J Multidiscip Healthc 2023; 16:1531-1540. [PMID: 37283950 PMCID: PMC10239642 DOI: 10.2147/jmdh.s407908] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2023] [Accepted: 04/06/2023] [Indexed: 06/08/2023] Open
Abstract
Background Hepatocellular carcinoma (HCC) is a heterogeneous disease that typically arises in the setting of chronic liver disease, making treatment selection complex. Multidisciplinary liver tumor boards (MDLTB) have been shown to improve outcomes in patients with HCC. However, in many cases, patients evaluated by MDLTBs ultimately do not receive the board's recommended treatment. Purpose This study aims to assess adherence to MDLTB recommendations for the treatment of HCC, the reasons for non-adherence, and the survival of Barcelona Clinic Liver Cancer (BCLC) Stage A patients treated with curative treatment compared to palliative locoregional therapy. Patients and Methods A single-site, retrospective cohort study was conducted of all patients with treatment-naïve HCC who were evaluated by an MDLTB at a tertiary care center in Connecticut between 2013 and 2016, of which 225 patients met inclusion criteria. Investigators conducted a chart review and recorded adherence to the MDLTB's recommendations, and in cases of discordance, evaluated and recorded the underlying cause; investigators assessed MDLTB recommendations' compliance with BCLC guidelines. Survival data was accrued through February 1st of 2022 and analyzed via Kaplan-Meier analysis and multivariate Cox regression. Results Treatment adherent to MDLTB recommendations occurred in 85.3% of patients (n=192). The majority of non-adherence occurred in the management of BCLC Stage A disease. In cases where adherence was possible but the recommendation was not followed, most discrepancies were whether to treat with curative or palliative intent (20/24), with almost all discrepancies occurring in patients (19/20) with BCLC Stage A disease. For patients with Stage A unifocal HCC, those who received curative therapy lived significantly longer than patients who received palliative locoregional therapy (5.55 years vs 4.26 years, p=0.037). Conclusion Most forms of non-adherence to MDLTB recommendations were unavoidable; however, treatment discordance in the management of patients with BCLC Stage A unifocal disease may present an opportunity for clinically significant quality improvement.

Abstract
BACKGROUND AND AIMS Studies have demonstrated that reducing farnesoid X receptor activity with ursodeoxycholic acid (UDCA) downregulates angiotensin-converting enzyme in human lung, intestinal and cholangiocytes organoids in vitro, in human lungs and livers perfused ex situ, reducing internalization of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) into the host cell. This offers a potential novel target against coronavirus disease 2019 (COVID-19). The objective of our study was to compare the association between UDCA exposure and SARS-CoV-2 infection, as well as varying severities of COVID-19, in a large national cohort of participants with cirrhosis. METHODS In this retrospective cohort study among participants with cirrhosis in the Veterans Outcomes and Costs Associated with Liver cohort, we compared participants with exposure to UDCA, with a propensity score (PS) matched group of participants without UDCA exposure, matched for clinical characteristics, and vaccination status. The outcomes included SARS-CoV-2 infection, symptomatic, at least moderate, severe, or critical COVID-19, and COVID-19-related death. RESULTS We compared 1607 participants with cirrhosis who were on UDCA, with 1607 PS-matched controls. On multivariable logistic regression, UDCA exposure was associated with reduced odds of developing SARS-CoV-2 infection (adjusted odds ratio [aOR] 0.54, 95% confidence interval [CI] 0.41-0.71, p < 0.0001). Among patients who developed COVID-19, UDCA use was associated with reduced disease severity, including symptomatic COVID-19 (aOR 0.54, 95% CI 0.39-0.73, p < 0.0001), at least moderate COVID-19 (aOR 0.51, 95% CI 0.32-0.81, p = 0.005), and severe or critical COVID-19 (aOR 0.48, 95% CI 0.25-0.94, p = 0.03). CONCLUSIONS In participants with cirrhosis, UDCA exposure was associated with both a decrease in SARS-CoV-2 infection, and reduction in symptomatic, at least moderate, and severe/critical COVID-19.

Abstract
As the third most common cause of cancer-related death worldwide with significant mortality rates in the United States, hepatocellular carcinoma has strong association with cirrhosis and chronic hepatitis B virus (HBV) with a growing at-risk population from the rise in chronic liver disease from alcohol use and nonalcoholic fatty liver disease. Despite this, progress in identifying at-risk individuals and early detection of HCC in these populations have lagged behind treatment advances.The lack of consensus may undermine widespread adoption of surveillance programs, thus preventing HCC detection at a curable stage. This public policy corner piece focuses on opportunities for prevention of HCC by focusing on its principal risk factors: viral hepatitis, NAFLD, and alcohol-related liver disease, and three key action points to reverse the course of this public health crisis: 1) Awareness and education; 2) Screening and diagnosis, and 3) Partnerships and advocacy.

Abstract
BACKGROUND Mental health diagnoses are common and known to impact key outcomes in patients with chronic illnesses including cirrhosis. However, the independent impact of psychiatric comorbidities on mortality in these patients and potential mitigating effects of outpatient mental health-related care has not been well characterized. METHODS This was a retrospective cohort study of patients with cirrhosis in the Veterans Health Administration between 2008 and 2021. Adjusted Cox regression was performed to evaluate the association between mental health-related diagnoses [groups: alcohol use disorder (AUD)/substance use disorder (SUD) alone, non-AUD/SUD alone, and any mental health diagnosis (AUD/SUD or non-AUD/SUD)] and all-cause mortality. In subgroup analyses, the impact of regular outpatient mental health visits was also assessed. RESULTS We identified 115,409 patients, 81.7% of whom had any mental health diagnosis at baseline. During the study window there was a significant increase in the number of mental health clinic visits per person-year (β=0.078, 95% CI: 0.065-0.092, p < 0.001), but a decrease in AUD/SUD clinic utilization (p < 0.001). In regression models, there was a 54% increased hazard in all-cause mortality for any mental health diagnosis, 11% for non-AUD/SUD, and 44% for AUD/SUD (each p < 0.001). Regular mental health visits resulted in a 21% decreased risk in all-cause mortality for AUD/SUD diagnosis, compared with 3% and 9% for any mental health diagnosis and non-AUD/SUD diagnosis, respectively (each p < 0.001). CONCLUSIONS Mental illness is associated with an increased risk of all-cause mortality in veterans with cirrhosis. Regular outpatient mental health care may be protective against all-cause mortality, particularly among patients with AUD/SUD. Future studies should focus on relevant clinical practice changes, including implementing integrated care programs.

Abstract
BACKGROUND Collection of accurate Hispanic ethnicity data is critical to evaluate disparities in health and health care. However, this information is often inconsistently recorded in electronic health record (EHR) data. OBJECTIVE To enhance capture of Hispanic ethnicity in the Veterans Affairs EHR and compare relative disparities in health and health care. METHODS We first developed an algorithm based on surname and country of birth. We then determined sensitivity and specificity using self-reported ethnicity from the 2012 Veterans Aging Cohort Study survey as the reference standard and compared this to the research triangle institute race variable from the Medicare administrative data. Finally, we compared demographic characteristics and age-adjusted and sex-adjusted prevalence of conditions in Hispanic patients among different identification methods in the Veterans Affairs EHR 2018-2019. RESULTS Our algorithm yielded higher sensitivity than either EHR-recorded ethnicity or the research triangle institute race variable. In 2018-2019, Hispanic patients identified by the algorithm were more likely to be older, had a race other than White, and foreign born. The prevalence of conditions was similar between EHR and algorithm ethnicity. Hispanic patients had higher prevalence of diabetes, gastric cancer, chronic liver disease, hepatocellular carcinoma, and human immunodeficiency virus than non-Hispanic White patients. Our approach evidenced significant differences in burden of disease among Hispanic subgroups by nativity status and country of birth. CONCLUSIONS We developed and validated an algorithm to supplement Hispanic ethnicity information using clinical data in the largest integrated US health care system. Our approach enabled clearer understanding of demographic characteristics and burden of disease in the Hispanic Veteran population.

Abstract
BACKGROUND Acute-on-chronic liver failure (ACLF) is a syndrome in patients with cirrhosis with high short-term mortality. Infection is a frequent precipitant of ACLF; however, it is unclear if prognosis varies by difference infectious sources. To address this knowledge gap, we utilized a large national database of patients with cirrhosis. METHODS This was a retrospective cohort study of patients with cirrhosis in the Veterans Health Administration between 2008 and 2016. First ACLF hospitalizations were identified and infections were classified using validated algorithms, categorized as bacteremia, fungal, spontaneous bacterial peritonitis (SBP), pyelonephritis/urinary tract infection, or skin and soft tissue/musculoskeletal infection (SST/MSK). Inverse probability treatment weighing for infection-associated ACLF followed by multivariable logistic regression was used to evaluate the association between infection type and 90-day mortality. RESULTS A total 22,589 ACLF hospitalizations were included, 3998 (17.7%) of which had ACLF grade 3. Infection was associated with 12,405 (54.9%) of ACLF hospitalizations. In regression models, SBP was associated with a 1.79-fold increased odds of 90-day mortality vs. no infection (95% confidence interval [CI] 1.58-2.02, p < 0.001), whereas SST/MSK infections had a lower relative odds of mortality (odds ratio 0.48, 95% CI 0.42-0.53, p < 0.001). There was a significant interaction between infection category and ACLF grade on the outcome of 90-day mortality (p < 0.001). CONCLUSIONS The impact of infection on short-term mortality in ACLF varies depending on the source of infection. This has relevance for ACLF prognostication and challenges previous notions that bacterial infection invariably worsens prognosis among all patients with ACLF.

Abstract
INTRODUCTION We studied longitudinal trends in mortality, outpatient, and inpatient care for cirrhosis in a national cohort in the first 2 years of the coronavirus disease-2019 pandemic. We evaluated trends in hepatocellular carcinoma (HCC) surveillance and factors associated with completion. METHODS Within the national cirrhosis cohort in the Veterans Administration from 2020 to 2021, we captured mortality, outpatient primary care provider, gastroenterology/hepatology (GI/HEP) visits, and hospitalizations. HCC surveillance was computed as percentage of time up to date with surveillance every 6 months (PTUDS). Multivariable models for PTUDS were adjusted for patient demographics, clinical factors, and facility-level variables. RESULTS The total cohort was 68,073; 28,678 were eligible for HCC surveillance. Outpatient primary care provider and GI/HEP appointment rates initially dropped from 30% to 7% with a rebound 1 year into the pandemic and steady subsequent use. Telemedicine monthly visit rates rose from less than 10% to a peak of 20% with a steady gradual decline. Nearly 70% of Veterans were up to date with HCC surveillance before the pandemic with an early pandemic nadir of approximately 50% and 60% PTUDS 2 years into the pandemic. In adjusted models, use of a population-based cirrhosis dashboard (β 8.5, 95% CI 6.9-10.2) and GI/HEP visits both in-person (β 3.2, 95% CI 2.9-3.6) and telemedicine (β 2.1, 95% CI 1.9-2.4) were associated with a higher PTUDS. DISCUSSION Outpatient utilization and HCC surveillance rates have rebounded but remain below at baseline. Population-based approaches and specialty care for cirrhosis were associated with a higher completion of HCC surveillance.

Abstract
BACKGROUND AND AIMS Little is known about the effectiveness of nonselective beta blockers (NSBBs) in preventing hepatic decompensation in routine clinical settings. We investigated whether NSBBs are associated with hepatic decompensation or liver-related mortality in a national cohort of veterans with Child-Turcotte-Pugh (CTP) A cirrhosis with no prior decompensations. APPROACH AND RESULTS In an active comparator, new user (ACNU) design, we created a cohort of new users of carvedilol ( n = 123) versus new users of selective beta blockers (SBBs) ( n = 561) and followed patients for up to 3 years. An inverse probability treatment weighting (IPTW) approach balanced demographic and clinical confounders. The primary analysis simulated intention-to-treat ("pseudo-ITT") with IPTW-adjusted Cox models; secondary analyses were pseudo-as-treated, and both were adjusted for baseline and time-updating drug confounders. Subgroup analyses evaluated NSBB effects by HCV viremia status, CTP class, platelet count, alcohol-associated liver disease (ALD) etiology, and age. In pseudo-ITT analyses of carvedilol versus SBBs, carvedilol was associated with a lower hazard of any hepatic decompensation (HR 0.59, 95% CI 0.42-0.83) and the composite outcome of hepatic decompensation/liver-related mortality (HR 0.56, 95% CI 0.41-0.76). Results were similar in pseudo-as-treated analyses (hepatic decompensation: HR 0.55, 95% CI 0.33-0.94; composite outcome: HR 0.62, 95% 0.38-1.01). In subgroup analyses, carvedilol was associated with lower hazard of primary outcomes in the absence of HCV viremia, higher CTP class and platelet count, younger age, and ALD etiology. CONCLUSIONS There is an ongoing need to noninvasively identify patients who may benefit from NSBBs for the prevention of hepatic decompensation.

Abstract
BACKGROUND AND AIMS Immunity to SARS-CoV-2 can be infection or vaccine-induced. Cirrhosis is associated with vaccine hyporesponsiveness, but whether there is decreased immunity after SARS-CoV-2 infection in unvaccinated patients with cirrhosis is unknown.The objective of our study was to compare infection-induced and vaccine-induced immunity against COVID-19 among patients with cirrhosis. METHODS This was a retrospective cohort study among US Veterans with cirrhosis between November 27, 2020, and November 16, 2021, comparing a vaccine-induced immunity group, defined as participants without a documented SARS-CoV-2 infection but fully vaccinated with two doses of an mRNA vaccine, and infection-associated immunity group, defined as unvaccinated participants who had a positive SARS-CoV-2 polymerase chain reaction (PCR). Both groups were propensity score matched for observed characteristics, including location, and the date of the immunity acquiring event, to control for the community prevalence of COVID-19 variants. The outcome was a positive SARS-CoV-2 PCR more than 60 days after previous infection in the infection-induced, or after full vaccination in the vaccine-induced immunity group. RESULTS We compared 634 participants in the infection-induced immunity group with 27,131 participants in the vaccine-induced immunity group using inverse propensity of treatment weighting. Vaccine-induced immunity was associated with a reduced odds of developing SARS-CoV-2 infection (adjusted hazard ratio [aHR], 0.18; 95% confidence interval [CI], 0.16-0.20, p < 0.0001). On multivariable logistic regression, vaccine-induced immunity was associated with reduced odds of developing symptomatic (adjusted odds ratio [aOR], 0.36; 95% CI, 0.33-0.41, p < 0.0001), moderate/severe/critical (aOR, 0.27; 95% CI, 0.22-0.31, p < 0.0001), and severe or critical COVID-19 (aOR, 0.20; 95% CI, 0.16-0.26, p < 0.001), compared with infection-induced immunity. CONCLUSIONS In participants with cirrhosis, vaccine-induced immunity is associated with reduced risk of developing COVID-19, compared with infection-induced immunity.

Abstract
Hepatocellular carcinoma (HCC) is a common complication in patients with chronic liver disease and leads to significant morbidity and mortality. Liver disease and liver cancer are preventable by mitigating and managing common risk factors, including chronic hepatitis B and C infection, alcohol use, diabetes, obesity and other components of the metabolic syndrome. The management of patients with HCC requires treatment of the malignancy and adequate control of the underlying liver disease, as preserving liver function is critical for successful cancer treatment and may have a relevant prognostic role independent of HCC management. Hepatologists are the ideal providers to guide the care of patients with HCC as they are trained to identify patients at risk, apply appropriate surveillance strategies, assess and improve residual liver function, evaluate candidacy for transplant, provide longitudinal care to optimize and preserve liver function during and after HCC treatment, survey for cancer recurrence and manage its risk factors, and prevent and treat decompensating events. We highlight the need for a team-based holistic approach to the patient with liver disease and HCC and identify necessary gaps in current care and knowledge.

[PMID: 36181987 PMCID: PMC9519143 DOI: 10.1016/j.jhep.2022.07.036] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2022] [Revised: 07/05/2022] [Accepted: 07/06/2022] [Indexed: 02/06/2023]
Abstract
BACKGROUND & AIMS Cirrhosis is associated with immune dysregulation and hyporesponsiveness to several vaccines including those against COVID-19. Our aim was to compare outcomes between patients with cirrhosis who received 3 doses of either the Pfizer BNT162b2 mRNA or Moderna mRNA-1273 vaccines to a propensity-matched control group of patients at similar risk of infection who received 2 doses. METHODS This was a retrospective cohort study of patients with cirrhosis who received 2 or 3 doses of a COVID-19 mRNA vaccine at the Veterans Health Administration. Participants who received 3 doses of the vaccine (n = 13,041) were propensity score matched with 13,041 controls who received 2 doses, and studied between July 18, 2021 and February 11, 2022, when B.1.617.2 (delta) and B.1.1.529 (omicron) were the predominant variants. Outcomes were aggregated as all cases with COVID-19, symptomatic COVD-19, with at least moderate COVID-19, or severe or critical COVID-19. RESULTS Receipt of the third dose of a COVID-19 mRNA vaccine was associated with an 80.7% reduction in COVID-19 (95% CI 39.2-89.1, p <0.001), an 80.4% reduction in symptomatic COVID-19, an 80% reduction in moderate, severe or critical COVID-19, (95% CI 34.5-87.6%, p = 0.005), a 100% reduction in severe or critical COVID-19 (95% CI 99.2-100.0, p = 0.01), and a 100% reduction in COVID-19-related death (95% CI 99.8-100.0, p = 0.007). The magnitude of reduction in COVID-19 was greater with the third dose of BNT 162b2 than mRNA-1273 and among participants with compensated rather than decompensated cirrhosis. CONCLUSIONS Administration of a third dose of a COVID-19 mRNA vaccine was associated with a more significant reduction in COVID-19 in patients with cirrhosis than in the general population, suggesting that the third dose can overcome vaccine hyporesponsiveness in this population. LAY SUMMARY Cirrhosis is associated with decreased responsiveness to several vaccines, including those against COVID-19. In this study of 26,082 participants with cirrhosis during the delta and omicron surge, receipt of the third dose of the vaccine was associated with an 80% reduction in COVID-19, a 100% reduction in severe/critical COVID-19, and a 100% reduction in COVID-19-related death. These findings support the importance of a third dose of mRNA vaccine among patients with cirrhosis.

Impact of NAFLD on clinical outcomes in hepatocellular carcinoma treated with sorafenib: an international cohort study. Therap Adv Gastroenterol 2022; 15:17562848221100106. [PMID: 36199289 PMCID: PMC9527996 DOI: 10.1177/17562848221100106] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2021] [Accepted: 04/21/2022] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND The impact of nonalcoholic fatty liver disease (NAFLD) on overall survival (OS), treatment response and toxicity in patients with hepatocellular carcinoma (HCC) treated with sorafenib is unknown. We examined the impact of NAFLD on survival and toxicity in an international cohort of patients receiving sorafenib. METHODS Clinical and demographic data were collected from patients consecutively treated at specialist centres in Europe and North America. The impact of NAFLD on OS, sorafenib-specific survival and toxicity compared with other aetiologies of liver disease using multivariable Cox-proportional hazards and logistic regression modelling was assessed. RESULTS A total of 5201 patients received sorafenib; 183 (3.6%) had NAFLD-associated HCC. NAFLD-associated HCC patients were more likely to be older women (median age 65.8 versus 63.0 years, p < 0.01 and 10.4% versus 2.3%, < 0.01), with a median body mass index (BMI) of 29.4. After controlling for known prognostic factors, no difference in OS in patients with or without NAFLD was observed [hazard ratio (HR): 0.99, 95% confidence interval (CI): 0.84-1.18, p = 0.98]. NAFLD-associated patients had more advanced stage HCC when they commenced sorafenib [Barcelona Clinic Liver Class (BCLC) C/D 70.9% versus 58.9%, p < 0.01] and were more likely to be commenced on a lower starting dose of sorafenib (51.4 versus 36.4%, p < 0.01). There was no difference in sorafenib-specific survival between NAFLD and other aetiologies (HR: 0.96, 95% CI: 0.79-1.17, p = 0.96). Adverse events were similar between NAFLD and non-NAFLD HCC groups, including rates of greater than grade 2 hypertension (6.3% versus 5.8%, p = 1.00). CONCLUSION Survival in HCC does not appear to be influenced by the presence of NAFLD. NAFLD-associated HCC derive similar clinical benefit from sorafenib compared with other aetiologies.

Cancer tracking system improves timeliness of liver cancer care at a Veterans Hospital: A comparison of cohorts before and after implementation of an automated care coordination tool. PLOS DIGITAL HEALTH 2022; 1:e0000080. [PMID: 36812575 PMCID: PMC9931271 DOI: 10.1371/journal.pdig.0000080] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/15/2022] [Accepted: 06/26/2022] [Indexed: 12/24/2022]
Abstract
INTRODUCTION Hepatocellular carcinoma (HCC) requires complex care coordination. Patient safety may be compromised with untimely follow-up of abnormal liver imaging. This study evaluated whether an electronic case-finding and tracking system improved timeliness of HCC care. METHODS An electronic medical record-linked abnormal imaging identification and tracking system was implemented at a Veterans Affairs Hospital. This system reviews all liver radiology reports, generates a queue of abnormal cases for review, and maintains a queue of cancer care events with due dates and automated reminders. This is a pre-/post-intervention cohort study to evaluate whether implementation of this tracking system reduced time between HCC diagnosis and treatment and time between first liver image suspicious for HCC, specialty care, diagnosis, and treatment at a Veterans Hospital. Patients diagnosed with HCC in the 37 months before tracking system implementation were compared to patients diagnosed with HCC in the 71 months after its implementation. Linear regression was used to calculate mean change in relevant intervals of care adjusted for age, race, ethnicity, BCLC stage, and indication for first suspicious image. RESULTS There were 60 patients pre-intervention and 127 post-intervention. In the post-intervention group, adjusted mean time from diagnosis to treatment was 36 days shorter (p = 0.007), time from imaging to diagnosis 51 days shorter (p = 0.21), and time from imaging to treatment 87 days shorter (p = 0.05). Patients whose imaging was performed for HCC screening had the greatest improvement in time from diagnosis to treatment (63 days, p = 0.02) and from first suspicious image to treatment (179 days, p = 0.03). The post-intervention group also had a greater proportion of HCC diagnosed at earlier BCLC stages (p<0.03). CONCLUSIONS The tracking system improved timeliness of HCC diagnosis and treatment and may be useful for improving HCC care delivery, including in health systems already implementing HCC screening.

Postvaccination COVID-19 infection is associated with reduced mortality in patients with cirrhosis. Hepatology 2022; 76:126-138. [PMID: 35023206 PMCID: PMC9015228 DOI: 10.1002/hep.32337] [Citation(s) in RCA: 45] [Impact Index Per Article: 22.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/06/2021] [Revised: 12/12/2021] [Accepted: 01/08/2022] [Indexed: 02/03/2023]
Abstract
BACKGROUND AND AIMS Patients develop breakthrough COVID-19 infection despite vaccination. The aim of this study was to identify outcomes in patients with cirrhosis who developed postvaccination COVID-19. METHODS We performed a retrospective cohort study among US veterans with cirrhosis and postvaccination or unvaccinated COVID-19. Patients were considered fully vaccinated if COVID-19 was diagnosed 14 days after the second dose of either the Pfizer BNT162b2, the Moderna 1273-mRNA, or the single-dose Janssen Ad.26.COV2.S vaccines and partially vaccinated if COVID-19 was diagnosed 7 days after the first dose of any vaccine but prior to full vaccination. We investigated the association of postvaccination COVID-19 with mortality. RESULTS We identified 3242 unvaccinated and 254 postvaccination COVID-19 patients with cirrhosis (82 after full and 172 after partial vaccination). In a multivariable analysis of a 1:2 propensity-matched cohort including vaccinated (n = 254) and unvaccinated (n = 508) participants, postvaccination COVID-19 was associated with reduced risk of death (adjusted HR [aHR], 0.21; 95% CI, 0.11-0.42). The reduction was observed after both full (aHR, 0.22; 95% CI, 0.08-0.63) and partial (aHR, 0.19; 95% CI, 0.07-0.54) vaccination, following the 1273-mRNA (aHR, 0.12; 95% CI 0.04-0.37) and BNT162b2 (aHR, 0.27; 95% CI, 0.10-0.71) vaccines and among patients with compensated (aHR, 0.19; 95% CI, 0.08-0.45) and decompensated (aHR, 0.27; 95% CI, 0.08-0.90) cirrhosis. Findings were consistent in a sensitivity analysis restricted to participants who developed COVID-19 after vaccine availability. CONCLUSIONS Though patients with cirrhosis can develop breakthrough COVID-19 after full or partial vaccination, these infections are associated with reduced mortality.

The Association Between Proton Pump Inhibitor Exposure and Key Liver-Related Outcomes in Patients With Cirrhosis: A Veterans Affairs Cohort Study. Gastroenterology 2022; 163:257-269.e6. [PMID: 35398042 PMCID: PMC10020994 DOI: 10.1053/j.gastro.2022.03.052] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/09/2021] [Revised: 03/24/2022] [Accepted: 03/29/2022] [Indexed: 12/13/2022]
Abstract
BACKGROUND & AIMS The impact of proton pump inhibitory (PPI) medications on adverse outcomes in cirrhosis remains controversial. We aimed to evaluate the association between PPI exposure and all-cause mortality, infection, and decompensation in a large national cohort. METHODS This was a retrospective study of patients with cirrhosis in the Veterans Health Administration. PPI exposure was classified as a time-updating variable from the index time of the cirrhosis diagnosis. Inverse probability treatment weighting-adjusted Cox regression was performed with additional adjustment for key time-varying covariates, including cardiovascular comorbidities, gastrointestinal bleeding (GIB), and statin exposure. RESULTS The study included 76,251 patients, 23,628 of whom were on a PPI at baseline. In adjusted models, binary (yes/no) PPI exposure was associated with reduced hazard of all-cause mortality in patients with hospitalization for GIB (hazard ratio [HR], 0.88; 95% confidence interval [CI], 0.84-0.91; P < .001) but had no significant association in all others (HR, 0.99; 95% CI, 0.97-1.02; P = .58). However, cumulative PPI exposure was associated with increased mortality in patients without hospitalization for GIB (HR, 1.07 per 320 mg-months [omeprazole equivalents]; 95% CI, 1.06-1.08; P < .001). PPI exposure was significantly associated with severe infection (HR, 1.21; 95% CI, 1.18-1.24; P < .001) and decompensation (HR, 1.64; 95% CI, 1.61-1.68; P < .001). In a cause-specific mortality analysis, PPI exposure was associated with increased liver-related mortality (HR, 1.23; 95% CI, 1.19-1.28) but with decreased nonliver-related mortality (HR, 0.88; 95% CI, 0.85-0.91). CONCLUSIONS PPI exposure is associated with increased risk of infection and decompensation in cirrhosis, which may mediate liver-related mortality. However, PPI use was associated with reduced all-cause mortality in those with prior GIB, suggesting benefit in the presence of an appropriate indication.

Abstract
BACKGROUND Little is known about use of specialty care among patients admitted with cirrhosis complications. AIMS We sought to characterize the use and impact of gastroenterology/hepatology (GI/HEP) consultations in hospitalized patients with cirrhosis. We studied two national cohorts-the Veterans Affairs Costs and Outcomes in Liver Disease (VOCAL) and a nationally representative database of commercially insured patients (Optum Clinformatics™ DataMart). METHODS Cirrhosis-related admissions were classified by ICD9/10 codes for ascites, hepatic encephalopathy, alcohol-associated hepatitis, spontaneous bacterial peritonitis, or infection related. We included 20,287/222,166 index admissions from VOCAL/Optum from 2010 to 2016. Propensity-matched analyses were conducted to balance clinical characteristics. Mortality and readmission were evaluated using competing risk regression (subhazard ratios, sHR), and length of stay (LOS) was assessed using negative binomial regression. RESULTS GI/HEP consultations were completed among 37% and 42% patients in VOCAL and Optum, respectively. In propensity-matched analyses for VOCAL, GI/HEP consultation was associated with adjusted estimates of increased LOS (1.55 + 1.03 additional days), 90-day mortality (sHR 1.23, 95% CI 1.14-1.36), and lower 30-day readmissions (sHR 0.82, 95% CI 0.75-0.89). In Optum, inpatient consultation was associated with higher LOS (1.13 + 1.01 additional days), higher 90-day mortality (sHR 1.57, 95% CI 1.43-1.72), and higher 30-day readmission risk (sHR 1.04, 95% CI 1.02-1.05). Post-discharge primary and specialty care was higher among admissions receiving GI/HEP consultation in both cohorts. CONCLUSIONS Use of GI/HEP consultation for cirrhosis-related admissions was low. Patients who received consultation had higher disease severity, and consultation was not associated with lower mortality but was associated with lower 30-day readmissions in the VA cohort only.

Risk Prediction Models for Postoperative Decompensation and Infection in Patients With Cirrhosis: A Veterans Affairs Cohort Study. Clin Gastroenterol Hepatol 2022; 20:e1121-e1134. [PMID: 34246794 PMCID: PMC8741885 DOI: 10.1016/j.cgh.2021.06.050] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2021] [Revised: 06/08/2021] [Accepted: 06/18/2021] [Indexed: 02/07/2023]
Abstract
BACKGROUND AND AIMS Patients with cirrhosis have an increased risk of postoperative mortality for a range of surgeries; however, they are also at risk of postoperative complications such as infection and cirrhosis decompensation. To date, there are no prediction scores that specifically risk stratify patients for these morbidities. METHODS This was a retrospective study using data of patients with cirrhosis who underwent diverse surgeries in the Veterans Health Administration. Validated algorithms and/or manual adjudication were used to ascertain postoperative decompensation and postoperative infection through 90 days. Multivariable logistic regression was used to evaluate prediction models in derivation and validation sets using variables from the recently-published Veterans Outcomes and Costs Associated with Liver Disease (VOCAL)-Penn cirrhosis surgical risk scores for postoperative mortality. Models were compared with the Mayo risk score, Model for End-stage Liver Disease (MELD)-sodium, and Child-Turcotte-Pugh (CTP) scores. RESULTS A total 4712 surgeries were included; patients were predominantly male (97.2 %), white (63.3 %), and with alcohol-related liver disease (35.3 %). Through 90 postoperative days, 8.7 % of patients experienced interval decompensation, and 4.5 % infection. Novel VOCAL-Penn prediction models for decompensation demonstrated good discrimination for interval decompensation (C-statistic 0.762 vs 0.663 Mayo vs 0.603 MELD-sodium vs 0.560 CTP; P < .001); however, discrimination was only fair for postoperative infection (C-statistic 0.666 vs 0.592 Mayo [P = .13] vs 0.502 MELD-sodium [P < .001] vs 0.503 CTP [P < .001]). The model for interval decompensation had excellent calibration in both derivation and validation sets. CONCLUSION We report the derivation and internal validation of a novel, parsimonious prediction model for postoperative decompensation in patients with cirrhosis. This score demonstrated superior discrimination and calibration as compared with existing clinical standards, and will be available at www.vocalpennscore.com.

Abstract
BACKGROUNDS & AIMS There is a need to identify therapies that prevent the development of acute-on-chronic liver failure (ACLF) in patients with cirrhosis. This study sought to evaluate the association between statin exposure and the risk of developing ACLF in a large national cohort of patients with cirrhosis. METHODS We performed a retrospective cohort study of patients diagnosed with cirrhosis within the Veterans Health Administration from 2008 and 2018. Patients were stratified into 3 groups based on statin exposure (statin naïve, existing statin user, and new statin initiator). Cox proportional hazards regression models with inverse probability treatment weighting and marginal structural models were utilized to comprehensively address potential confounding in estimating the association between time-updated statin exposure and first occurrence of high-grade ACLF. RESULTS The cohort included 84,963 patients, of whom 26.9% were on a statin at baseline. A total of 8,558 (10.1%) patients with cirrhosis were hospitalized with high-grade ACLF over a median follow-up time of 51.6 months (IQR 27.5-81.4). Time-updated statin use was associated with a significant reduction in the hazard of developing ACLF (hazard ratio [HR] 0.62, 95% CI 0.59-0.65, p <0.001). Increasing doses of statin were associated with progressively reduced hazard of developing ACLF (HR 0.75, 95% CI 0.66-0.86, p <0.001 for <20 mg vs. 0 mg of time-updated statin exposure, in simvastatin equivalents; HR 0.61, 95%, CI 0.58-0.64, p <0.001 for >20 mg vs. 0 mg statin exposure). Furthermore, every additional 5 months of statin exposure was associated with a 9% reduced hazard of high-grade ACLF (HR 0.91, 95% CI 0.90-0.92, p <0.001). CONCLUSIONS In this large, retrospective, cohort study in patients with cirrhosis, statin use was significantly associated with reduced development of high-grade ACLF. LAY SUMMARY Statin therapy has been shown to have numerous beneficial effects in patients with chronic liver disease. This study demonstrated a strong association between statin therapy and a reduced risk of acute-on-chronic liver failure development in patients with cirrhosis. The results of this study support the promising role that statins may play in future prevention of acute-on-chronic liver failure in patients with cirrhosis.

Race Adjustment in eGFR Equations Does Not Improve Estimation of Acute Kidney Injury Events in Patients with Cirrhosis. Dig Dis Sci 2022; 67:1399-1408.

Abstract
BACKGROUND Accuracy of glomerular filtration rate estimating (eGFR) equations has significant implications in cirrhosis, potentially guiding simultaneous liver kidney allocation and drug dosing. Most equations adjust for Black race, partially accounted for by reported differences in muscle mass by race. Patients with cirrhosis, however, are prone to sarcopenia which may mitigate such differences. We evaluated the association between baseline eGFR and incident acute kidney injury (AKI) in patients with cirrhosis with and without race adjustment. METHODS We conducted a retrospective national cohort study of veterans with cirrhosis. Baseline eGFR was calculated using multiple eGFR equations including Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI), both with and without race adjustment. Poisson regression was used to investigate the association between baseline eGFR and incident AKI events per International Club of Ascites criteria. RESULTS We identified 72,267 patients with cirrhosis, who were 97.3% male, 57.8% white, and 19.7% Black. Over median follow-up 2.78 years (interquartile range 1.22-5.16), lower baseline eGFR by CKD-EPI was significantly associated with higher rates of AKI in adjusted models. For all equations this association was minimally impacted when race adjustment was removed. For example, removal of race adjustment from CKD-EPI resulted in a 0.1% increase in the association between lower eGFR and higher rate of AKI events per 15 mL/min/1.73 m2 change (p < 0.001). CONCLUSIONS Race adjustment in eGFR equations did not enhance AKI risk estimation in patients with cirrhosis. Further study is warranted to assess the impacts of removing race from eGFR equations on clinical outcomes and policy.

Abstract
BACKGROUND The natural history of patients with anti-mitochondrial antibody (AMA)-negative Primary Biliary Cholangitis (PBC) cirrhosis has not been well defined, with prior studies showing discordant results. Furthermore, most studies of AMA-negative PBC have limited numbers of patients with cirrhosis and liver-related outcomes. METHODS We investigated the association of AMA-negative PBC and the development of death, liver-related death, decompensation and hepatocellular carcinoma (HCC), in a large cohort of predominantly male patients with PBC cirrhosis assembled from the Veterans Health Administration. RESULTS In a cohort of 521 patients with PBC cirrhosis (65 AMA-negative) with a total follow-up of 2504.3 person-years (PY) from cirrhosis diagnosis, patients with AMA-negative PBC were younger and more likely to be black but had similar rates of UDCA response. AMA-negative PBC cirrhosis was associated with similar unadjusted rates of liver-related death (4.6 vs 5.9 per 100 PY, P = .44), overall death (7.7 vs 9.6 per 100 PY, P = .31), decompensation (7.3 vs 5.1 per 100 PY, P = .12) and HCC (0.6 vs 1.0 per 100 PY, P = .63) to AMA-positive PBC. After adjusting for confounders, AMA-negative PBC cirrhosis was associated with similar rates of liver-related death (sub-Hazard Ratio [sHR] 1.27, 95% CI 0.71-2.28, P = .42, death [sHR] 1.24, 95% CI 0.81-1.90, P = .32), decompensation (sHR 1.05, 95% CI 0.56-1.98, P = .87) and HCC (sHR 0.48, 95% CI 0.11-2.10, P = .33) to AMA-positive patients. CONCLUSION In a cohort of predominantly male patients, AMA-negative PBC cirrhosis was associated with similar rates of overall or liver-related death, HCC or decompensation compared with AMA-positive disease.

Abstract
BACKGROUND Successful liver transplantation offers the possibility of improved survival among patients with decompensated cirrhosis. However, there is wide variability in access to care and promptness of the transplant evaluation process in the United States. METHODS We performed a multicenter retrospective study of 1118 patients who underwent evaluation for liver transplantation at the 6 Veterans Affairs' transplant centers from 2013 to 2018. Of these, 832 patients were evaluated within 30 d and 286 > 30 d after referral. We studied the differential effects of the time from referral to evaluation on pretransplant and posttransplant mortality and transplant list dropout and explored predictors of early transplant evaluation. RESULTS Patients in the early evaluation group had a shorter adjusted time from referral to listing by 29.5 d (95% confidence interval [CI] -50.4, -8.5, P < 0.006), and referral to transplantation by 115.1 d (95% CI -179.5, -50.7, P < 0.0001). On a multivariable Cox hazard model, evaluation within 30 d of referral was associated with a significantly lower pretransplant mortality (adjusted hazard ratio [aHR] 0.70, 95% CI 0.54-0.91, P < 0.01), but not associated with transplant list dropout (aHR 0.95, 95% CI 0.65-1.39, P = 0.79) or posttransplant death (aHR 1.88, 95% CI 0.72-4.9, P = 0.20). An early evaluation within 30 d was positively associated with a higher MELD at referral (aHR 1.03, 95% CI 1.01-1.06, P = 0.006) and negatively associated with distance from the transplant center (aHR 0.99, 95% CI 0.99-0.99, P = 0.045). CONCLUSIONS Evaluation of patients referred for liver transplantation within 30 d is associated with a reduction in pretransplant mortality.

Oral Cyanobacteria and Hepatocellular Carcinoma. Cancer Epidemiol Biomarkers Prev 2022; 31:221-229. [PMID: 34697061 PMCID: PMC8755591 DOI: 10.1158/1055-9965.epi-21-0804] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Revised: 09/22/2021] [Accepted: 10/14/2021] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND Gut microbial alterations have been linked to chronic liver disease and hepatocellular carcinoma (HCC). The role of the oral microbiome in liver cancer development has not been widely investigated. METHODS Bacterial 16S rRNA sequences were evaluated in oral samples from 90 HCC cases and 90 controls who were a part of a larger U.S. case-control study of HCC among patients diagnosed from 2011 to 2016. RESULTS The oral microbiome of HCC cases showed significantly reduced alpha diversity compared with controls (Shannon P = 0.002; Simpson P = 0.049), and beta diversity significantly differed (weighted Unifrac P = 0.004). The relative abundance of 30 taxa significantly varied including Cyanobacteria, which was enriched in cases compared with controls (P = 0.018). Cyanobacteria was positively associated with HCC [OR, 8.71; 95% confidence interval (CI), 1.22-62.00; P = 0.031] after adjustment for age, race, birthplace, education, smoking, alcohol, obesity, type 2 diabetes, Hepatitis C virus (HCV), Hepatitis B virus (HBV), fatty liver disease, aspirin use, other NSAID use, laboratory batch, and other significant taxa. When stratified by HCC risk factors, significant associations of Cyanobacteria with HCC were exclusively observed among individuals with negative histories of established risk factors as well as females and college graduates. Cyanobacterial genes positively associated with HCC were specific to taxa producing microcystin, the hepatotoxic tumor promotor, and other genes known to be upregulated with microcystin exposure. CONCLUSIONS Our study provides novel evidence that oral Cyanobacteria may be an independent risk factor for HCC. IMPACT These findings support future studies to further examine the causal relationship between oral Cyanobacteria and HCC risk.

Protease inhibitor-based direct-acting antivirals are associated with increased risk of aminotransferase elevations but not hepatic dysfunction or decompensation. J Hepatol 2021; 75:1312-1322. [PMID: 34333102 PMCID: PMC8604762 DOI: 10.1016/j.jhep.2021.07.021] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2020] [Revised: 07/14/2021] [Accepted: 07/18/2021] [Indexed: 12/04/2022]
Abstract
BACKGROUND & AIMS Cases of acute liver injury (ALI) have been reported among chronic HCV-infected patients receiving protease inhibitor (PI)-based direct-acting antiviral (DAA) regimens, but no analyses have compared the risk of ALI in patients receiving PI- vs. non-PI-based DAAs. Thus, we compared the risk of 3 ALI outcomes between patients (by baseline Fibrosis-4 [FIB-4] group) receiving PI-based or non-PI-based DAAs. METHODS We conducted a cohort study of 18,498 patients receiving PI-based DAA therapy (paritaprevir/ritonavir/ombitasvir±dasabuvir, elbasvir/grazoprevir, glecaprevir/pibrentasvir) matched 1:1 on propensity score to those receiving non-PI-based DAAs (sofosbuvir/ledipasvir, sofosbuvir/velpatasvir) in the 1945-1965 Veterans Birth Cohort (2014-2019). During exposure to DAA therapy, we determined development of: i) alanine aminotransferase (ALT) >200 U/L, ii) severe hepatic dysfunction (coagulopathy with hyperbilirubinemia), and iii) hepatic decompensation. We used Cox regression to determine hazard ratios (HRs) with 95% CIs for each ALI outcome within groups defined by baseline FIB-4 (≤3.25; >3.25). RESULTS Among patients with baseline FIB-4 ≤3.25, those receiving PIs had a higher risk of ALT >200 U/L (HR 3.98; 95% CI 2.37-6.68), but not severe hepatic dysfunction (HR 0.67; 95% CI 0.19-2.39) or hepatic decompensation (HR 1.01; 95% CI 0.29-3.49), compared to those receiving non-PI-based regimens. For those with baseline FIB-4 >3.25, those receiving PIs had a higher risk of ALT >200 U/L (HR, 2.15; 95% CI 1.09-4.26), but not severe hepatic dysfunction (HR, 1.23 [0.64-2.38]) or hepatic decompensation (HR, 0.87; 95% CI 0.41-1.87), compared to those receiving non-PI-based regimens CONCLUSION: While risk of incident ALT elevations was increased in those receiving PI-based DAAs in both FIB-4 groups, the risk of severe hepatic dysfunction and hepatic decompensation did not differ between patients receiving PI- or non-PI-based DAAs in either FIB-4 group. LAY SUMMARY Cases of liver injury have been reported among patients treated with protease inhibitor-based direct-acting antivirals for hepatitis C infection, but it is not clear if the risk of liver injury among people starting these drugs is increased compared to those starting non-protease inhibitor-based therapy. In this study, patients receiving protease inhibitor-based treatment had a higher risk of liver inflammation than those receiving a non-protease inhibitor-based treatment, regardless of the presence of pre-treatment advanced liver fibrosis/cirrhosis. However, the risk of severe liver dysfunction and decompensation were not higher for patients treated with protease inhibitor-based regimens.

Palliative Care Always: Hepatology-Virtual Primary Palliative Care Training for Hepatologists. Hepatol Commun 2021; 6:920-930. [PMID: 34719137 PMCID: PMC8948550 DOI: 10.1002/hep4.1849] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/06/2021] [Revised: 09/22/2021] [Accepted: 10/10/2021] [Indexed: 01/08/2023] Open
Abstract
Palliative care (PC) benefits patients with serious illness including end-stage liver disease (ESLD). As part of a cluster randomized trial, hepatologists were trained to deliver primary palliative care to patients with ESLD using an online course, Palliative Care Always: Hepatology (PCA:Hep). Here we present a multimethod formative evaluation (feasibility, knowledge acquisition, self-efficacy, and practice patterns) of PCA:Hep. Feasibility was measured by completion of coursework and achieving a course grade of >80%. Knowledge acquisition was measured through assessments before and throughout the course. Pre/post-course surveys were conducted to determine self-efficacy and practice patterns. The hepatologists (n = 39) enrolled in a 12-week online course and spent 1-3 hours on the course weekly. The course was determined to be feasible as 97% successfully completed the course and 100% passed. The course was acceptable to participants; 91.7 % reported a positive course experience and satisfaction with knowledge gained (91.6%). The pre/post knowledge assessment showed an improvement of 6.0% (pre 85.9% to post 91.9%, 95% CI [2.8, 9.2], P = 0.001). Self-efficacy increased significantly (P < 0.001) in psychological symptom management, hospice, and psychosocial support. A year after training, over 80% of the hepatologists reported integrating a variety of PC skills into routine patient care. Conclusion: PCA:Hep is feasible, acceptable, and improves learner knowledge and confidence in palliative care skills. This is a viable method to teach primary PC skills to specialists caring for patients with ESLD.

Abstract
IMPORTANCE Two mRNA-based vaccines against coronavirus disease 2019 (COVID-19) were found to be highly efficacious in phase 3 clinical trials in the US. However, patients with chronic illnesses, including cirrhosis, were excluded from clinical trials. Patients with cirrhosis have immune dysregulation that is associated with vaccine hyporesponsiveness. OBJECTIVE To study the association of receipt of the Pfizer BNT162b2 mRNA or the Moderna mRNA-1273 vaccines in patients with cirrhosis compared with a propensity-matched control group of patients at similar risk of infection and severe disease from COVID-19. DESIGN, SETTING, AND PARTICIPANTS We performed a retrospective cohort study of patients with cirrhosis who received at least 1 dose of a COVID-19 mRNA vaccine at the Veterans Health Administration. Patients who received at least 1 dose of the vaccine (n = 20 037) were propensity matched with 20 037 controls to assess the associations of vaccination with new COVID-19 infection and COVID-19 hospitalization and death. EXPOSURES Receipt of at least 1 dose of the BNT162b2 mRNA or the mRNA-1273 vaccines between December 18, 2020, and March 17, 2021. MAIN OUTCOMES AND MEASURES COVID-19 infection as documented by a positive result for COVID-19 by polymerase chain reaction, hospitalization, and death due to COVID-19 infection. RESULTS The median (interquartile range) age of the vaccinated individuals in the study cohort was 69.1 (8.4) years and 19 465 (97.2%) of the participants in each of the vaccinated and unvaccinated groups were male, consistent with a US veteran population. The mRNA-1273 vaccine was administered in 10 236 (51%) and the BNT162b2 mRNA in 9801 (49%) patients. Approximately 99.7% of patients who received the first dose of either vaccine with a follow-up of 42 days or more received a second dose. The number of COVID-19 infections in the vaccine recipients was similar to the control group in days 0 to 7, 7 to 14, 14 to 21, and 21 to 28 after the first dose. After 28 days, receipt of 1 dose of an mRNA vaccine was associated with a 64.8% reduction in COVID-19 infections and 100% protection against hospitalization or death due to COVID-19 infection. The association of reduced COVID-19 infections after the first dose was lower among patients with decompensated (50.3%) compared with compensated cirrhosis (66.8%). Receipt of a second dose was associated with a 78.6% reduction in COVID-19 infections and 100% reduction in COVID-19-related hospitalization or death after 7 days. CONCLUSIONS AND RELEVANCE This cohort study of US veterans found that mRNA vaccine administration was associated with a delayed but modest reduction in COVID-19 infection but an excellent reduction in COVID-19-related hospitalization or death in patients with cirrhosis.
