Understanding the Changing Landscape of Health Disparities in Chronic Liver Diseases and Liver Cancer

Validity of patient-reported information: agreement rate between patient reports and registry data

BACKGROUND

The accuracy of patient-reported clinical information, including cancer stage, is not well understood. This study aims to evaluate the agreement between patient-reported survey data and clinical information recorded in hospital-based cancer registries (HBCR).

METHODS

A total of 730 patients from 166 hospitals in Japan were randomly selected and informed that their survey responses would be validated against HBCR data. Demographic details, including age, sex, cancer stage, and cancer site, were recorded and compared with clinical data from the HBCR. Agreement rates between patients' self-reported demographic and clinical data and the corresponding HBCR records were analyzed. Logistic regression analysis was conducted to identify factors associated with accurate reporting of cancer stage information.

RESULTS

Agreement rates for age, sex, and cancer site were 99.4%, 99.8%, and over 90% across all cancer sites, respectively. The agreement rate for cancer stage reporting was 49.9%. Patients with stage IV cancer had the highest agreement rate at 68.4%. Patients under 75 years of age and those with specific cancer types demonstrated higher odds of reporting data consistent with HBCR records.

CONCLUSIONS

For cancer stage data, relying on more credible sources, such as cancer registries, is recommended over patient-reported information to ensure accuracy.

Alcohol-Related Liver Disease, Followed by Metabolic Dysfunction-Associated Steatotic Liver Disease, Emerges as the Fastest-Growing Aetiologies for Primary Liver Cancer in the United States

OBJECTIVE

Primary liver cancer (PLC) is projected to be the third leading cause of cancer mortality in the United States in 2040. We examine the burden of PLC in the United States, stratified by sex, state and aetiological risk factors.

METHODS

Data on PLC prevalence, incidence, death and disability-adjusted life years (DALYs) were extracted from the Global Burden of Disease Study 2021. Changes in these parameters were calculated using the Joinpoint regression model.

RESULTS

There were 47,970 cases, 31,450 incident cases, 24,770 deaths and 576,920 DALYs from PLC in the United States. The highest prevalence (16,980), incidence (12,040), death (9840) and DALYs (213,410) from PLC were due to chronic hepatitis C virus infection. From 2000 to 2021, PLC incidences increased by 141%, and PLC deaths increased by 136%. Age-standardised incidence rates (ASIRs) and death rates (ASDRs) per 100,000 population for PLC increased, primarily driven by alcohol-related liver disease (ALD) (ASIR: annual percent change [APC]: +2.40%; ASDR: APC: +2.22%) and metabolic dysfunction-associated steatotic liver disease (MASLD) (ASIR: APC: +2.32%; ASDR: APC: +2.04%).

CONCLUSION

The burden of PLC in the United States has risen in the past two decades, driven mainly by ALD and followed by MASLD. These findings offer policymakers an accurate assessment of the PLC burden and emphasise the need for targeted risk factor mitigation, especially regarding alcohol related policy.

Poverty Traps and Mortality From Liver Diseases in the United States

INTRODUCTION

Poverty traps, locations with multigenerational poverty, result from structural and economic factors that can affect health of residents within these locations. The aim of this study was to define poverty traps within the contiguous United States and their impact on outcomes from liver diseases or cancers.

METHODS

A systematic census-tract level analysis was used to spatially define regions that encompassed poverty traps. Clusters of prevalent poverty and mortality from chronic liver diseases or liver cancers were identified. Temporal trends and the relationship between race and ethnicity, type of space and escape from poverty traps on disease mortality within hot spots were determined.

RESULTS

The proportion of census tracts enduring multigenerational poverty within counties was strongly associated with mortality from liver disease or cancer. There was a highly significant clustering of persistent poverty and increased mortality. Hot spots of high-mortality areas correlated with factors related to income, ethnicity, and access to health care. Location or noneconomic individual factors such as race and ethnicity were important determinants of disparities within hot spots. Distinct groups of poverty traps were defined. The highly characteristic demographics and disease outcomes within each of these groups underscored the need for location-specific interventions.

DISCUSSION

Poverty traps are a major and important spatially determined risk factor for mortality from liver diseases and cancers. Targeted location-specific interventions and economic development aimed at addressing the underlying causes of poverty and enhancing prosperity will be required to reduce mortality from liver diseases within poverty traps.

Food inequity and insecurity and MASLD: burden, challenges, and interventions

Liver disease prevalence, severity, outcomes and hepatic risk factors (for example, unhealthy diet) are heavily affected by socioeconomic status and food insecurity. Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most prevalent liver disease globally and is likely to co-occur with other liver diseases associated with food insecurity. Though weight reduction and adopting a healthy diet can reverse the course of MASLD, gaps between recommendations and practice transcend individual responsibility and preference. Broader sociocultural determinants of food choices (social nutrition) include food insecurity, community and social norms and the local environment, including commercial pressures that target people experiencing poverty, ethnic minorities and children. Food insecurity is a barrier to a healthy diet, as a low-quality diet is often less expensive than a healthy one. Consequently, food insecurity is an 'upstream' risk factor for MASLD, advanced fibrosis and greater all-cause mortality among patients with liver disease. Intervening on food insecurity at four major levels (environment, policy, community and health care) can reduce the burden of liver disease, thereby reducing social and health inequities. In this Review, we report on the current research in the field, the need for implementing proven interventions, and the role liver specialists can have.

Barriers and Strategies to Effective Serious Illness Communication for Patients with End-Stage Liver Disease in the Intensive Care Setting

Background: Patients with end-stage liver disease (ESLD) often require Intensive Care Unit (ICU) admission during the disease trajectory, but aggressive medical treatment has not resulted in increased quality of life for patients or caregivers. Methods: This narrative review synthesizes relevant data thematically exploring the current state of serious illness communication in the ICU with identification of barriers and potential strategies to improve performance. We provide a conceptual model underscoring the importance of providing comprehensible disease and prognosis knowledge, eliciting patient values and aligning these values with available goals of care options through a series of discussions. Achieving effective serious illness communication supports the delivery of goal concordant care (care aligned with the patient's stated values) and improved quality of life. Results: General barriers to effective serious illness communication include lack of outpatient serious illness communication discussions; formalized provider training, literacy and culturally appropriate patient-directed serious illness communication tools; and unoptimized electronic health records. ESLD-specific barriers to effective serious illness communication include stigma, discussing the uncertainty of prognosis and provider discomfort with serious illness communication. Evidence-based strategies to address general barriers include using the Ask-Tell-Ask communication framework; clinician training to discuss patients' goals and expectations; PREPARE for Your Care literacy and culturally appropriate written and online tools for patients, caregivers, and clinicians; and standardization of documentation in the electronic health record. Evidence-based strategies to address ESLD-specific barriers include practicing with empathy; using the "Best-Case, Worst Case" prognostic framework; and developing interdisciplinary solutions in the ICU. Conclusion: Improving clinician training, providing patients and caregivers easy-to-understand communication tools, standardizing EHR documentation, and improving interdisciplinary communication, including palliative care, may increase goal concordant care and quality of life for critically ill patients with ESLD.

Disparities in hepatocellular carcinoma incidence among Hispanic and non-Hispanic adults in Arizona: Trends between 2009-2017

BACKGROUND

Hepatocellular carcinoma (HCC) is a highly lethal cancer with few treatment options available to patients. Most HCC cases in Arizona, a state with a high proportion of Hispanic adults, have not been included in recent reports of HCC incidence. This study describes trends in HCC incidence and stage at diagnosis among Arizona residents between 2009-2017 and reports on racial and ethnic disparities for these outcomes.

METHODS

The Arizona Cancer Registry was used to identify Arizonans aged 19 or older diagnosed with liver cell carcinoma diagnosed between 2009-2017. A total of 5043 cases were examined. Adjusted annual and 3-year HCC incidence rates (per 100,000) were examined for non-Hispanic White (NHW) and Hispanic adults.

RESULTS

The total age-adjusted HCC incidence rate increased significantly between 2009-2012 and then declined significantly between 2012-2017. Across nearly all years, age-adjusted HCC incidence in Hispanic adults was twice that of NHW adults. Hispanic adults were more likely to be diagnosed at a later stage across all time periods. The disparity in 3-year age-adjusted HCC incidence rate between NHW and Hispanic adults decreased between 2009-2017.

CONCLUSION

Whe total age-adjusted HCC incidence rate increased significantly between 2009-2012 and then declined significantly between 2012-2017. Across nearly all years, age-adjusted HCC incidence in Hispanic adults was twice that of NHW adults. Hispanic adults were more likely to be diagnosed at a later stage across all time periods. The disparity in 3-year age-adjusted HCC incidence rate between NHW and Hispanic adults decreased between 2009-2017.

Geographic disparities in access to liver transplant for advanced cirrhosis: Time to ring the alarm!

Decompensated cirrhosis and hepatocellular cancer are major risk factors for mortality worldwide. Liver transplantation (LT), both live-donor LT or deceased-donor LT, are lifesaving, but there are several barriers toward equitable access. These barriers are exacerbated in the setting of critical illness or acute-on-chronic liver failure. Rates of LT vary widely worldwide but are lowest in lower-income countries owing to lack of resources, infrastructure, late disease presentation, and limited donor awareness. A recent experience by the Chronic Liver Disease Evolution and Registry for Events and Decompensation consortium defined these barriers toward LT as critical in determining overall survival in hospitalized cirrhosis patients. A major focus should be on appropriate, affordable, and early cirrhosis and hepatocellular cancer care to prevent the need for LT. Live-donor LT is predominant across Asian countries, whereas deceased-donor LT is more common in Western countries; both approaches have unique challenges that add to the access disparities. There are many challenges toward equitable access but uniform definitions of acute-on-chronic liver failure, improving transplant expertise, enhancing availability of resources and encouraging knowledge between centers, and preventing disease progression are critical to reduce LT disparities.
