Declining Cirrhosis Hospitalizations in the Wake of the COVID-19 Pandemic: A National Cohort Study

Cost of Care for Patients With Cirrhosis

INTRODUCTION

There are limited longitudinal data on the cost of treating patients with cirrhosis, which hampers value-based improvement initiatives.

METHODS

We conducted a retrospective cohort study of patients with cirrhosis seen in the Veterans Affairs health care system from 2011 to 2015. Patients were followed up through 2019. We identified a sex-matched and age-matched control cohort without cirrhosis. We estimated incremental annual health care costs attributable to cirrhosis for 4 years overall and in subgroups based on severity (compensated, decompensated), cirrhosis complications (ascites, encephalopathy, varices, hepatocellular cancer, acute kidney injury), and comorbidity (Deyo index).

RESULTS

We compared 39,361 patients with cirrhosis with 138,964 controls. The incremental adjusted costs for caring of patients with cirrhosis were $35,029 (95% confidence interval $32,473-$37,585) during the first year and ranged from $14,216 to $17,629 in the subsequent 3 years. Cirrhosis complications accounted for most of these costs. Costs of managing patients with hepatic encephalopathy (year 1 cost, $50,080) or ascites ($50,364) were higher than the costs of managing patients with varices ($20,488) or hepatocellular cancer ($37,639) in the first year. Patients with acute kidney injury or those who had multimorbidity were the most costly at $64,413 and $66,653 in the first year, respectively.

DISCUSSION

Patients with cirrhosis had substantially higher health care costs than matched controls and multimorbid patients had even higher costs. Cirrhosis complications accounted for most of the excess cost, so preventing complications has the largest potential for cost saving and could serve as targets for improvement.

COVID-19, Possible Hepatic Pathways and Alcohol Abuse-What Do We Know up to 2023?

The pandemic period due to coronavirus disease 2019 (COVID-19) revolutionized all possible areas of global health. Significant consequences were also related to diverse extrapulmonary manifestations of this pathology. The liver was found to be a relatively common organ, beyond the respiratory tract, affected by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Multiple studies revealed the essential role of chronic liver disease (CLD) in the general outcome of coronavirus infection. Present concerns in this field are related to the direct hepatic consequences caused by COVID-19 and pre-existing liver disorders as risk factors for the severe course of the infection. Which mechanism has a key role in this phenomenon-previously existing hepatic disorder or acute liver failure due to SARS-CoV-2-is still not fully clarified. Alcoholic liver disease (ALD) constitutes another not fully elucidated context of coronavirus infection. Should the toxic effects of ethanol or already developed liver cirrhosis and its consequences be perceived as a causative or triggering factor of hepatic impairment in COVID-19 patients? In the face of these discrepancies, we decided to summarize the role of the liver in the whole picture of coronavirus infection, paying special attention to ALD and focusing on the pathological pathways related to COVID-19, ethanol toxicity and liver cirrhosis.

Assessment of quality of care for hospitalized non-COVID-19 older adult patients with pneumonia before and after the COVID-19 pandemic

BACKGROUND

There is limited research into the clinical implications of the coronavirus disease 2019 (COVID-19) pandemic for non-COVID-19 pneumonia in older adults, as well as their quality of care or outcomes. This study aims to assess the process and outcome quality of care for hospitalized older adult patients with pneumonia before and after the pandemic.

METHODS

A retrospective cohort of older adult patients (age ≥ 65) hospitalized for non-COVID pneumonia were recruited from five Korean hospitals (January 20, 2019, to January 19, 2021). The quality of care before and after the COVID-19 pandemic was evaluated.

RESULTS

A total of 7356 hospitalization episodes of older adult pneumonia were identified, and 978 cases (552 pre-pandemic and 426 during the pandemic) were analyzed. The pneumonia severity score was higher during the pandemic, and the waiting time from the emergency room to admission was also longer. Furthermore, the pneumonia mortality rate during the pandemic was higher than that in the pre-pandemic period (in-hospital mortality: 10.1% vs. 18.1%; 90-day mortality: 11.6% vs. 22.3%). A significantly higher mortality risk was observed during the pandemic than in the period prior (adjusted odds ratio: 1.74, 95% confidence interval: 1.14-2.63).

CONCLUSIONS

While the quality of care for hospitalized pneumonia has been maintained during the pandemic, there has been an increase in mortality rates. Further investigations are needed to understand the underlying causes of this increase.

Mortality Increased Among Hospitalized Patients with Cirrhosis Before and Following Different Waves of the COVID-19 Pandemic

BACKGROUND

The Coronavirus disease 2019 (COVID-19) pandemic disrupted patient care and worsened the morbidity and mortality of some chronic diseases. The impact of the COVID-19 pandemic on hospitalizations and outcomes in patients with cirrhosis both before and during different time periods of the pandemic has not been evaluated.

AIMS

Describe characteristics of hospitalized patients with cirrhosis and evaluate inpatient mortality and 30-day readmission before and after the start of the COVID-19 pandemic.

METHODS

Retrospective single-center cohort study of all hospitalized patients with cirrhosis from 2018 to 2022. Time periods within the COVID-19 pandemic were defined using reference data from the World Health Organization and Centers for Disease Control. Adjusted odds ratios from logistic regression were used to assess differences between periods.

RESULTS

33,926 unique hospitalizations were identified. Most patients were over age 60 years across all time periods of the pandemic. More Hispanic patients were hospitalized during COVID-19 than before COVID-19. Medicare and Medicaid are utilized less frequently during COVID-19 than before COVID-19. After controlling for age and gender, inpatient mortality was significantly higher during all COVID-19 periods except Omicron compared to before COVID-19. The odds of experiencing a 30-day readmission were 1.2 times higher in the pre-vaccination period compared to the pre-COVID-19 period.

CONCLUSION

Inpatient mortality among patients with cirrhosis has increased during the COVID-19 pandemic compared to before COVID-19. Although COVID-19 infection may have had a small direct pathologic effect on the natural history of cirrhotic liver disease, it is more likely that other factors are impacting this population.

Association between alcohol-associated cirrhosis and inpatient complications among COVID-19 patients: A propensity-matched analysis from the United States

BACKGROUND

Alcohol-associated cirrhosis (AC) contributes to significant liver-related mortality in the United States. It is known to cause immune dysfunction and coagulation abnormalities. Patients with comorbid conditions like AC are at risk of worse clinical outcomes from coronavirus disease 2019 (COVID-19). The specific association between AC and COVID-19 mortality remains inconclusive, given the lack of robust clinical evidence from prior studies.

AIM

To study the predictors of mortality and the outcomes of AC in patients hospitalized with COVID-19 in the United States.

METHODS

We conducted a retrospective cohort study using the National Inpatient Sample (NIS) database 2020. Patients were identified with primary COVID-19 hospitalizations based on an underlying diagnosis of AC. A matched comparison cohort of COVID-19 patients without AC was identified after 1:N propensity score matching based on baseline sociodemographic characteristics and Elixhauser comorbidities. Primary outcomes included median length of stay, median inpatient charges, and in-hospital mortality. Secondary outcomes included a prevalence of systemic complications.

RESULTS

A total of 1325 COVID-19 patients with AC were matched to 1135 patients without AC. There was no difference in median length of stay and hospital charges in COVID-19 patients with AC compared to non-AC (P > 0.05). There was an increased prevalence of septic shock (5.7% vs 4.1%), ventricular fibrillation/ventricular flutter (0.4% vs 0%), atrial fibrillation (13.2% vs 8.8%), atrial flutter (8.7% vs 4.4%), first-degree atrioventricular nodal block (0.8% vs 0%), upper extremity venous thromboembolism (1.5% vs 0%), and variceal bleeding (3.8% vs 0%) in the AC cohort compared to the non-AC cohort (P < 0.05). There was no difference in inpatient mortality in COVID-19 patients with non-AC compared to AC, with an odds ratio of 0.97 (95% confidence interval: 0.78-1.22, P = 0.85). Predictors of mortality included advanced age, cardiac arrhythmias, coagulopathy, protein-calorie malnutrition, fluid and electrolyte disorders, septic shock, and upper extremity venous thromboembolism.

CONCLUSION

AC does not increase mortality in patients hospitalized with COVID-19. There is an increased association between inpatient complications among COVID-19 patients with AC compared to non-AC.

COVID-19 in patients with liver disease and liver transplant: clinical implications, prevention, and management

The coronavirus disease 2019 (COVID-19) pandemic has had enormous implications for the care of patients with chronic liver disease (CLD), cirrhosis, and liver transplant (LT). Clinical outcomes of COVID-19 vary in patients with CLD and cirrhosis compared to healthy controls, and in patients with LT compared to patients without LT. Several special considerations apply to the approach to vaccination and treatment in patients with CLD and LT. The practice of liver transplantation has also been heavily impacted by the pandemic, including persistent reductions in living donor LT and increases in LT for an indication of alcohol-related liver disease. Recent medical society guidelines strive to standardize severe acute respiratory syndrome coronavirus 2 testing in donors and recipients and the approach to transplantation after recovered from COVID-19 infection, but certain controversies remain.

COVID-19 and severity of liver diseases: Possible crosstalk and clinical implications

COVID-19-infected individuals and those who recovered from the infection have been demonstrated to have elevated liver enzymes or abnormal liver biochemistries, particularly with preexisting liver diseases, liver metabolic disorders, viral hepatitis, and other hepatic comorbidities. However, possible crosstalk and intricate interplay between COVID-19 and liver disease severity are still elusive, and the available data are murky and confined. Similarly, the syndemic of other blood-borne infectious diseases, chemical-induced liver injuries, and chronic hepatic diseases continued to take lives while showing signs of worsening due to the COVID-19 crisis. Moreover, the pandemic is not over yet and is transitioning to becoming an epidemic in recent years; hence, monitoring liver function tests (LFTs) and assessing hepatic consequences of COVID-19 in patients with or without liver illnesses would be of paramount interest. This pragmatic review explores the correlations between COVID-19 and liver disease severity based on abnormal liver biochemistries and other possible mechanisms in individuals of all ages from the emergence of the COVID-19 pandemic to the post-pandemic period. The review also alludes to clinical perspectives of such interactions to curb overlapping hepatic diseases in people who recovered from the infection or living with long COVID-19.

Global epidemiology of cirrhosis - aetiology, trends and predictions

Cirrhosis is an important cause of morbidity and mortality in people with chronic liver disease worldwide. In 2019, cirrhosis was associated with 2.4% of global deaths. Owing to the rising prevalence of obesity and increased alcohol consumption on the one hand, and improvements in the management of hepatitis B virus and hepatitis C virus infections on the other, the epidemiology and burden of cirrhosis are changing. In this Review, we highlight global trends in the epidemiology of cirrhosis, discuss the contributions of various aetiologies of liver disease, examine projections for the burden of cirrhosis, and suggest future directions to tackle this condition. Although viral hepatitis remains the leading cause of cirrhosis worldwide, the prevalence of non-alcoholic fatty liver disease (NAFLD) and alcohol-associated cirrhosis are rising in several regions of the world. The global number of deaths from cirrhosis increased between 2012 and 2017, but age-standardized death rates (ASDRs) declined. However, the ASDR for NAFLD-associated cirrhosis increased over this period, whereas ASDRs for other aetiologies of cirrhosis declined. The number of deaths from cirrhosis is projected to increase in the next decade. For these reasons, greater efforts are required to facilitate primary prevention, early detection and treatment of liver disease, and to improve access to care.

SARS-CoV-2 induced liver injury: Incidence, risk factors, impact on COVID-19 severity and prognosis in different population groups

Liver is unlikely the key organ driving mortality in coronavirus disease 2019 (COVID-19) however, liver function tests (LFTs) abnormalities are widely observed mostly in moderate and severe cases. According to this review, the overall prevalence of abnormal LFTs in COVID-19 patients ranges from 2.5% to 96.8% worldwide. The geographical variability in the prevalence of underlying diseases is the determinant for the observed discrepancies between East and West. Multifactorial mechanisms are implicated in COVID-19-induced liver injury. Among them, hypercytokinemia with "bystander hepatitis", cytokine storm syndrome with subsequent oxidative stress and endotheliopathy, hypercoagulable state and immuno-thromboinflammation are the most determinant mechanisms leading to tissue injury. Liver hypoxia may also contribute under specific conditions, while direct hepatocyte injury is an emerging mechanism. Except for initially observed severe acute respiratory distress syndrome corona virus-2 (SARS-CoV-2) tropism for cholangiocytes, more recent cumulative data show SARS-CoV-2 virions within hepatocytes and sinusoidal endothelial cells using electron microscopy (EM). The best evidence for hepatocellular invasion by the virus is the identification of replicating SARS-CoV-2 RNA, S protein RNA and viral nucleocapsid protein within hepatocytes using in-situ hybridization and immunostaining with observed intrahepatic presence of SARS-CoV-2 by EM and by in-situ hybridization. New data mostly derived from imaging findings indicate possible long-term sequelae for the liver months after recovery, suggesting a post-COVID-19 persistent live injury.

Patterns of Care Utilization and Hepatocellular Carcinoma Surveillance: Tracking Care Across the Pandemic

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.

Increasing Prevalence and Racial Disparity of Alcohol-Related Gastrointestinal and Liver Disease During the COVID-19 Pandemic: A Population-Based National Study

OBJECTIVES

One consequence of social distancing during the coronavirus disease 2019 (COVID-19) pandemic was an increase in alcohol use disorders. We postulated that this would be associated with a rise in alcohol-related gastrointestinal and liver disease.

METHODS

Using Explorys Inc., an aggregate of electronic health records from US health care systems from 1999 to June 2021, we identified patients with "alcoholic hepatitis," "inflammation of pancreas caused by alcohol," and "alcoholic gastritis," based on Systematized Nomenclature of Medicine-Clinical Terms (SNOMED-CT). We compared patients utilizing health care during the pandemic to those before it.

RESULTS

We identified 8,445,720 patients treated from June 21, 2020 to June 20, 2021 ("COVID cohort") and 65,587,860 patients treated before this ("pre-COVID cohort"). African American patients were more likely to be treated for all causes during COVID-19 [odds ratio (OR): 1.65; P <0.0001]. Alcoholic hepatitis (OR: 2.77), alcoholic pancreatitis (OR: 3.67), and alcoholic gastritis (OR: 1.70) (for each, P <0.0001) were more likely in all patients in the COVID cohort. African Americans in the COVID cohort were more likely to be diagnosed with alcoholic hepatitis (OR: 2.63), alcoholic pancreatitis (OR: 2.17), and alcoholic gastritis (OR: 3.09) [for each, P <0.0001].

CONCLUSIONS

The prevalence of alcohol-related liver and gastrointestinal disease increased during COVID-19. We suspect these increases are associated with increased alcohol use disorder resulting from the stress of social isolation. These data suggest COVID-19 disproportionately affected African Americans in overall health care utilization and increased burden of alcoholic gastrointestinal and liver disease.

Association of Heparin-Like Effect, Factor VII/XIII Deficiency and Fibrinolysis with Rebleeding Risk in Cirrhosis with Acute Variceal Bleeding

BACKGROUND

Hyperfibrinolysis and coagulation dysfunction may occur in cirrhotic patients with acute variceal bleed (AVB) despite successful endotherapy.

AIMS

To prospectively study the association of endogenous heparinoids and coagulation dysfunction with variceal rebleeding and outcome in cirrhosis.

METHODS

Consecutive patients were assessed with conventional coagulation tests, SONOCLOT™ [(global(gb) and heparinase(h) treated] and factors VII, VIII, XIII, X, tissue plasminogen activator, and plasminogen activator inhibitor ELISA assays in a university hospital. Heparin-like-effect (HLE) was defined as ≥ 20% difference in paired gb/h-SONOCLOT™ traces for activated clotting time (ACT).

RESULTS

Of 143 patients screened, 90 (46.4 ± 11.7 years, males 82.2%, ethanol-related 58.8%) were recruited, who bled from esophageal varices (81,90.0%), gastric varices (6,6.6%), or esophageal varices with portal hypertensive gastropathy (3,3.3%). Twenty (21.7%) had early rebleeding, mainly post-variceal ligation ulcer related (70%). Patients who rebled had low Factor XIII [1.6 (1.2-2.1) vs 2.4 ng/ml (2.0-2.8) P = 0.035] and Factor VII (94.1 ± 46.9 vs. 124.0 ± 50.4, P = 0.023). On receiver operating curve analysis, the gbACT > 252 s (sensitivity 86.8%, specificity 76.9%, P < 0.001), hACT > 215 s (sensitivity 71.1%, specificity 70.3%, P < 0.001), and HLE > 50% (sensitivity 69.5%, specificity 70.3%, P = 0.006) predicted rebleeding. Baseline Factor VIII (HR 1.26; 95% CI 1.17-1.34, P < 0.001), low factor VII (HR 0.89; 95% CI 0.76-0.98, P = 0.035), and lysis (HR 1.25, 95% CI 1.17-1.33, P < 0.001) predicted mortality. Endogenous heparinoids at baseline predicted sepsis (HR 1.8; 95% CI 1.4-6.5; P = 0.022), rebleeding events (HR 1.2; 95% CI 1.1-6.3; P = 0.030), and mortality (HR 1.1; 95% CI 1.0-4.6; P = 0.030).

CONCLUSIONS

Hyperfibrinolysis, Factor VII/XIII deficiency, and HLE are associated with rebleeding after AVB. Trial Registration NCT04111120 available from https://clinicaltrials.gov/ct2/show/NCT04111120 .

Trends in gastrointestinal disease hospitalizations and outcomes during the first year of the coronavirus pandemic

BACKGROUND

The impact of the coronavirus on hospitalizations for gastrointestinal (GI) disease, particularly at a population level is understudied.

AIM

To investigate trends in hospitalizations, inpatient endoscopy resource utilization, and outcomes during the first year of the coronavirus pandemic and subsequent lockdowns.

METHODS

Using the California State Inpatient Database for 2018-2020, we explored year-to-year and 2020 month-to-month trends in hospitalizations, length of stay, and inpatient mortality (all-cause & viral pneumonia-specific) for common inpatient GI diagnoses including acute pancreatitis, diverticulitis, cholelithiasis, non-infectious gastroenteritis, upper and lower GI bleeding (LGIB), Clostridium difficile, viral gastroenteritis, inflammatory bowel disease, and acute cholangitis.

RESULTS

Disease-specific hospitalizations decreased for all included conditions except nonvariceal upper GI bleeding (NVUGIB), LGIB, and ulcerative colitis (UC) (ptrend < 0.0001). All-cause inpatient mortality was higher in 2020 vs 2019, for acute pancreatitis (P = 0.029), diverticulitis (P = 0.04), NVUGIB (P = 0.003), and Crohn’s disease (P = 0.004). In 2020, hospitalization rates were lowest in April, November, and December. There was no significant corresponding increase in inpatient mortality except in UC (ptrend = 0.048). Viral pneumonia and viral pneumonia complicated by respiratory failure increased (P < 0.001) among GI hospitalizations. Endoscopy utilization within 24 h of admission was unchanged for GI emergencies except NVUGIB (P < 0.001).

CONCLUSION

Our findings suggest that hospitalization rates for common GI conditions significantly declined in California during the COVID pandemic, particularly in April, November and December 2020. All-cause mortality was significantly higher among acute pancreatitis, diverticulitis, NVUGIB, and Crohn’s disease hospitalizations. Emergency endoscopy rates were mostly comparable between 2020 and 2019.

Negative impact of the pandemic on hospital admissions, morbidity and early mortality for acute cirrhosis decompensation

INTRODUCTION

The global pandemic has diverted resources away from management of chronic diseases, including cirrhosis. While there is increasing knowledge on COVID-19 infection in liver cirrhosis, little is described on the impact of the pandemic on decompensated cirrhosis admissions and outcomes, which was the aim of this study.

METHODS

A single-centre, retrospective study, evaluated decompensated cirrhosis admissions to a tertiary London hepatology and transplantation centre, from October 2018 to February 2021. Patients were included if they had an admission with cirrhosis decompensation defined as new-onset jaundice or ascites, infection, encephalopathy, portal hypertensive bleeding or renal dysfunction.

RESULTS

The average number of admissions stayed constant between the pre-COVID-19 (October 2018-February 2020) and COVID-19 periods (March 2020-February 2021). Patients transferred in from secondary centres had consistently higher severity scores during the COVID-19 period (UK Model for End-Stage Liver Disease 58 vs 54; p=0.007, Model for End-Stage Liver Disease-Sodium 22 vs 18; p=0.006, EF-CLIF Acute Decompensation (AD) score 55.0 vs 51.0; p=0.055). Of those admitted to the intensive care without acute-on-chronic liver failure, there was a significant increase in AD scores during the COVID-19 period (58 vs 48, p=0.009). In addition, there was a trend towards increased hospital readmission rates during the COVID-19 period (29.5% vs 21.5%, p=0.067). When censored at 30 days, early mortality postdischarge was significantly higher during the COVID-19 period (p<0.001) with a median time to death of 35 days compared with 62 days pre-COVID-19.

DISCUSSION

This study provides a unique perspective on the impact that the global pandemic had on decompensated cirrhosis admissions. The findings of increased early mortality and readmissions, and higher AD scores on ICU admission, highlight the need to maintain resourcing for high-level hepatology care and follow-up, in spite of other disease pressures.

Global epidemiology of alcohol-associated cirrhosis and HCC: trends, projections and risk factors

Heavy alcohol consumption is a major cause of morbidity and mortality. Globally, alcohol per-capita consumption rose from 5.5 litres in 2005 to 6.4 litres in 2016 and is projected to increase further to 7.6 litres in 2030. In 2019, an estimated 25% of global cirrhosis deaths were associated with alcohol. The global estimated age-standardized death rate (ASDR) of alcohol-associated cirrhosis was 4.5 per 100,000 population, with the highest and lowest ASDR in Africa and the Western Pacific, respectively. The annual incidence of hepatocellular carcinoma (HCC) among patients with alcohol-associated cirrhosis ranged from 0.9% to 5.6%. Alcohol was associated with approximately one-fifth of global HCC-related deaths in 2019. Between 2012 and 2017, the global estimated ASDR for alcohol-associated cirrhosis declined, but the ASDR for alcohol-associated liver cancer increased. Measures are required to curb heavy alcohol consumption to reduce the burden of alcohol-associated cirrhosis and HCC. Degree of alcohol intake, sex, older age, obesity, type 2 diabetes mellitus, gut microbial dysbiosis and genetic variants are key factors in the development of alcohol-associated cirrhosis and HCC. In this Review, we discuss the global epidemiology, projections and risk factors for alcohol-associated cirrhosis and HCC.

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

Liver disease and liver cancer disparities in the U.S. are reflective of complex multiple determinants of health. This review describes the disproportionate burden of liver disease and liver cancer among racial, ethnic, sexual, and gender minority, rural, low socioeconomic status (SES) populations, and place-based contexts. The contributions of traditional and lifestyle-related risk factors (e.g., alcohol consumption, evitable toxin exposure, nutrition quality) and comorbid conditions (e.g., viral hepatitis, obesity, type II diabetes) to disparities is also explored. Biopsychosocial mechanisms defining the physiological consequences of inequities underlying these health disparities, including inflammation, allostatic load, genetics, epigenetics, and social epigenomics are described. Guided by the National Institute on Minority Health and Health Disparities (NIMHD) framework, integrative research of unexplored social and biological mechanisms of health disparities, appropriate methods and measures for early screening, diagnosis, assessment, and strategies for timely treatment and maintaining multidisciplinary care should be actively pursued. We review emerging research on adverse social determinants of liver health, such as structural racism, discrimination, stigma, SES, rising care-related costs, food insecurity, healthcare access, health literacy, and environmental exposures to pollutants. Limited research on protective factors of liver health is also described. Research from effective, multilevel, community-based interventions indicate a need for further intervention efforts that target both risk and protective factors to address health disparities. Policy-level impacts are also needed to reduce disparities. These insights are important, as the social contexts and inequities that influence determinants of liver disease/cancer have been worsened by the coronavirus disease-2019 pandemic and are forecasted to amplify disparities.

Covid-19 and alcohol associated liver disease

The COVID-19 pandemic is having substantial impacts on the health status of individuals with alcohol use disorder (AUD) and alcohol-associated liver disease (ALD). AUD and ALD have both been impacted throughout the pandemic, with increases in alcohol use during the early stages of the pandemic, reduced access to treatment during the mid-pandemic, and challenges in managing the downstream effects in the post-COVID era. This review will focus on how the COVID-19 pandemic has impacted AUD and ALD epidemiology and access to treatment, and will discuss to address this rising AUD and ALD disease burden.

COVID-19 and liver disease

Knowledge on SARS-CoV-2 infection and its resultant COVID-19 in liver diseases has rapidly increased during the pandemic. Hereby, we review COVID-19 liver manifestations and pathophysiological aspects related to SARS-CoV-2 infection in patients without liver disease as well as the impact of COVID-19 in patients with chronic liver disease (CLD), particularly cirrhosis and liver transplantation (LT). SARS-CoV-2 infection has been associated with overt proinflammatory cytokine profile, which probably contributes substantially to the observed early and late liver abnormalities. CLD, particularly decompensated cirrhosis, should be regarded as a risk factor for severe COVID-19 and death. LT was impacted during the pandemic, mainly due to concerns regarding donation and infection in recipients. However, LT did not represent a risk factor per se of worse outcome. Even though scarce, data regarding COVID-19 specific therapy in special populations such as LT recipients seem promising. COVID-19 vaccine-induced immunity seems impaired in CLD and LT recipients, advocating for a revised schedule of vaccine administration in this population.

Alcohol use disorder and liver injury related to the COVID-19 pandemic

Alcohol use disorder is a complex and heterogeneous phenomenon that can be studied from several points of view by focusing on its different components. Alcohol is a hepatotoxin whose metabolism creates profound alterations within the hepatocyte. The liver is the central organ in the metabolism of alcohol, a process that also involves other organs and tissues such as the brain, heart and muscles, but the most relevant organ is the liver. The anatomopathological alterations in the liver associated with the prolonged use of alcohol range from the simple accumulation of neutral fats in the hepatocytes, to cirrhosis and hepatocellular carcinoma. Alcohol abuse frequently leads to liver disease such as steatosis, steatohepatitis, fibrosis, cirrhosis, and tumors. Following the spread of coronavirus disease 2019 (COVID-19), there was an increase in alcohol consumption, probably linked to the months of lockdown and smart working. It is known that social isolation leads to a considerable increase in stress, and it is also recognized that high levels of stress can result in an increase in alcohol intake. Cirrhotic patients or subjects with liver cancer are immunocompromised, so they may be more exposed to COVID-19 infection with a worse prognosis. This review focuses on the fact that the COVID-19 pandemic has made the emergence of alcohol-induced liver damage a major medical and social problem.

Impact of COVID-19 on Intracranial Meningioma Resection: Results from California State Inpatient Database

Simple Summary

All fields of healthcare were adversely affected by the COVID-19 pandemic. In this study, we sought to understand the effects of COVID-19 on hospitalizations for intracranial meningioma resection using a large database. We compared hospitalization rates as well as hospital outcomes such as Clavien–Dindo grade IV complications, in-hospital mortality, and prolonged length of stay for intracranial meningioma resection during 2019 and 2020. Our findings showed that though hospitalization rates decreased slightly during the COVID-19 pandemic, hospital outcomes were not adversely affected. The findings of our study show that with adequate planning and preparations, better hospital outcomes could be sustained even during healthcare emergencies such as COVID-19 pandemic. Our findings assure that neurosurgery practice in the US ensured the best quality of care to their patients even during COVID-19 pandemic.

Abstract

Purpose: To assess the effects of COVID-19 on hospitalizations for intracranial meningioma resection using a large database. Methods: We conducted a retrospective analysis of the California State Inpatient Database (SID) 2019 and 2020. All adult (18 years or older) hospitalizations were included for the analysis. The primary outcomes were trends in hospitalization for intracranial meningioma resection between 2019 and 2020. Secondary outcomes were Clavien–Dindo grade IV complications, in-hospital mortality, and prolonged length of stay, which was defined as length of stay ≥75 percentile. Results: There were 3,173,333 and 2,866,161 hospitalizations in 2019 and 2020, respectively (relative decrease, 9.7%), of which 921 and 788 underwent intracranial meningioma resection (relative decrease, 14.4%). In 2020, there were 94,114 admissions for COVID-19 treatment. Logistic regression analysis showed that year in which intracranial meningioma resection was performed did not show significant association with Clavien–Dindo grade IV complications and in-hospital mortality (OR, 1.23, 95% CI: 0.78–1.94) and prolonged length of stay (OR, 1.05, 95% CI: 0.84–1.32). Conclusion: Our findings show that neurosurgery practice in the US successfully adapted to the unforeseen challenges posed by COVD-19 and ensured the best quality of care to the patients.

Algorithms to Identify Alcoholic Hepatitis Hospitalizations in Patients with Cirrhosis

BACKGROUND

Alcoholic hepatitis (AH) is a clinically diagnosed syndrome with high short-term mortality for which liver transplantation may be curative. A lack of validated algorithms to identify AH hospitalizations has hindered clinical epidemiology research.

METHODS

This was a retrospective cohort study of patients with cirrhosis using Veterans Health Administration (VHA) data from 2008 to 2015. We randomly sampled hospitalizations based upon abnormal liver tests and administrative codes for acute hepatitis or alcohol-associated liver disease (ALD). Hospitalizations were manually adjudicated for AH per society guidelines. A priori algorithms were evaluated to compute positive predicted value (PPV) and positive likelihood ratio (LR+), and were tested in an external University of Pennsylvania Health System (UPHS) cohort.

RESULTS

Of 368 hospitalizations, 142 (38.6%) were adjudicated as AH. AH patients were younger (55 vs. 58 years, p < 0.001), less likely to have prior cirrhosis decompensation (57% vs. 73.9%, p < 0.001), and had higher AST-to-ALT ratios (median 2.9 vs. 1.9 mg/dL, p < 0.001) and higher bilirubin levels (median 2.9 vs. 1.9 mg/dL, p < 0.001). Algorithms combining clinical laboratory criteria (AST > 85 U/L but < 450 U/L, AST-to-ALT ratio > 2, total bilirubin > 5 mg/dL) and administrative coding criteria yielded the highest PPV (96.4%, 95% CI 87.7-99.6) and the highest LR+ (43.0, 95% CI 10.6-173.5). Several algorithms demonstrated 100% PPV for definite AH in the UPHS external cohort.

CONCLUSION

We have identified algorithms for AH hospitalizations with excellent PPV and LR+. These high-specificity algorithms may be used in VHA datasets to identify patients with high likelihood of AH, but should not be used to study AH incidence.

Major Shifts in Outpatient Cirrhosis Care Delivery Attributable to the COVID-19 Pandemic: A National Cohort Study

The coronavirus disease 2019 (COVID-19) pandemic has disrupted health care delivery in the United States, with increased reliance on telemedicine visits as opposed to in-person outpatient appointments. We used national data to evaluate shifts in modes of hepatology outpatient care for patients with cirrhosis during the pandemic. This was a retrospective cohort study among U.S. veterans with cirrhosis. We used linear regression to evaluate absolute and percentage changes from baseline in hepatology in-person visits and telemedicine visits from January 1, 2020, to August 11, 2020. The proportion of in-person and telemedicine visits were plotted geographically to demonstrate state-level shifts in care delivery over time. Patient-level characteristics in the pre-COVID and during-COVID periods were also compared. We identified 5,618 in-person and 6,210 telemedicine hepatology visits among patients with cirrhosis. In-person visits significantly declined (-16.0% per week; 95% confidence interval [CI] -20.7, -11.2; P < 0.001), while telemedicine visits significantly increased (61.3% per week; 95% CI 45.1, 77.5; P < 0.001) in the early during-COVID period. At the U.S. state level, we found that nearly all states experienced a significant shift toward telemedicine over the course of several weeks. Patients over the age of 70 years and Black patients were less likely to receive telemedicine visits in the pre-COVID period (each P < 0.05), although these differences were eliminated in the during-COVID periods. Conclusion: Among patients with cirrhosis, hepatology outpatient care delivery has shifted heavily toward telemedicine due to COVID-19. This occurred across the United States, and changes have been sustained through August 2020. Expanded telemedicine visits among older patients and Black patients may reflect dedicated efforts to increased access to care among these groups.

Collateral impact of the COVID−19 pandemic on the use of healthcare resources among people with disabilities

Objective

We assessed the collateral impact of the COVID−19 pandemic on healthcare service use among people with disabilities.

Methods

We utilized the COVID−19 database from the Korean National Health Insurance Service claims from 2015 until June 2020. We included 5,850 people with disabilities and matched 5,850 without disabilities among those who were neither tested nor diagnosed with COVID−19. We used a quasi–experimental setting with a COVID−19 outbreak as an external event in a difference–difference estimation with matching controls.

Results

Participants with disabilities recorded a larger decrease in the number of claims for total services (2.1 claims per 5 months) upon the COVID−19 pandemic's onset compared to those without disabilities (1.6 claims), and the difference–in–difference estimates were statistically significant (0.46 claims). The decline was driven by outpatient and emergency visits. The extent of the decline was large for the severe disability group overall. By disability type, those with a physical disability showed a statistically significant decline in the number of claims.

Conclusion

The COVID−19 pandemic has had a collateral impact on people with disabilities' use of healthcare services. Continued assessment is needed regarding whether the collateral impact has been sustained or is following a different path.

Survey of the Impact of COVID-19 on Chronic Liver Disease Patient Care Experiences and Outcomes

Background

The COVID-19 pandemic has a secondary impact on the health of patients with chronic liver disease (CLD). Our objective was to study this impact on care provision, telemedicine, and health behaviours in CLD patients.

Methods

CLD patients of an urban gastroenterology clinic who attended a telemedicine appointment between March 17, 2020 and September 17, 2020, completed an online survey on care delays, health behaviours, and experience with telemedicine. Chart review was conducted in 400 randomly selected patients: 200 charts from during the pandemic were compared to 200 charts the previous year. Data were extracted for clinicodemographic variables, laboratory investigations, and clinical outcomes.

Results

Of 399 patients invited to participate, 135 (34%) completed the online survey. Fifty (39%) patients reported 83 care delays due to the COVID-19 pandemic, with the majority (71%) of delays persisting beyond 2 months. Ninety-five (75%) patients were satisfied with telemedicine appointments. There was a longer delay between lab work and appointments in patients seen during the pandemic compared to 2019 (P = 0.01). Compared to the year prior, during the COVID pandemic, there was a similar number of cases of cirrhosis decompensation (n = 26, 13% versus n = 22, 11%) and hospitalization (n = 12, 6% versus n = 5, 3%).

Conclusion

The COVID-19 pandemic has led to care delays for CLD outpatients, with most delays on the scale of months. These patient-reported experiences and clinical observations can direct optimization of CLD care as effects from the pandemic evolve.

Patient-centered care: Key elements applicable to chronic liver disease

Chronic liver disease (CLD) is a progressive illness with high symptom burden and functional and cognitive impairment, often with comorbid mental and substance use disorders. These factors lead to significant deterioration in quality of life, with immense burden on patients, caregivers, and healthcare. The current healthcare system in the United States does not adequately meet the needs of patients with CLD or control costs given the episodic, reactive, and fee-for-service structure. There is also a need for clinical and financial accountability for CLD care. In this context, we describe the key elements required to shift the CLD care paradigm to a patient-centered and value-based system built upon the Porter model of value-based health care. The key elements include (1) organization into integrated practice units, (2) measuring and incorporating meaningful patient-reported outcomes, (3) enabling technology to allow innovation, (4) bundled care payments, (5) integrating palliative care within routine care, and (6) formalizing centers of excellence. These elements have been shown to improve outcomes, reduce costs, and improve overall patient experience for other chronic illnesses and should have similar benefits for CLD. Payers need to partner with providers and systems to build upon these elements and help align reimbursements with patients' values and outcomes. The national organizations such as the American Association for Study of Liver Diseases need to guide key stakeholders in standardizing these elements to optimize patient-centered care for CLD.

Decreased Rate of Presentation, but Worsened Racial-Ethnic Disparity in Acute Gastrointestinal Bleeding During Coronavirus 2019 Shutdown: A Retrospective Cohort Study

Purpose

In spring 2020, Coronavirus Disease 2019 (COVID-19) "stay-at-home" orders may have led to later, more acute disease presentations of emergent conditions such as gastrointestinal bleeding (GIB). In this retrospective cohort study, we compared incidence and severity of GIB during the strictest COVID shutdown to pre-COVID periods.

Patients and methods

We compared weekly counts of emergency department (ED) visits for GIB between March 27 and May 7, 2020 (COVID period) and pre-COVID periods in 2019 and 2020 in a US statewide network of hospitals. We compared the severity of GIB presentations using incident rate ratios (IRR) of "severe" GIB (requiring ≥4 units of blood, endoscopic therapy, interventional radiology or surgical procedure), intensive care (ICU) admission and shock. We also looked for effect modification of demographic covariates on associations between year and GIB outcomes.

Results

Fewer patients presented to ED for GIB during COVID than during the same dates in 2019 (534 versus 904; IRR 0.59, 95% CI 0.53-0.66). A greater proportion of COVID-period ED visits required inpatient admission (73.6% vs 67.8%, p = 0.02) and had severe GIB (19.3% vs 14.9%, p = 0.03). Proportion of patients requiring transfusion (p < 0.001), with shock (p < 0.01), or with critical hemoglobin (p = 0.003) or lactate (p = 0.02) were worse during COVID. Non-white patients experienced disproportionately worse outcomes during COVID than in 2019, with greater absolute counts of shock (65 vs 62, p = 0.01 for interaction) or ICU admission (40 vs 35, p = 0.01 for interaction).

Conclusion

Fewer acute GIB presented during the pandemic period compared to the year prior. The severity of pandemic presentations was greater, driven by disproportionately worse outcomes in minorities.

Coronavirus disease 2019 and the liver

PURPOSE OF REVIEW

The objective of this review is to examine the epidemiology and pathogenesis of liver injury in coronavirus disease 2019 (COVID-19) and the impact of COVID-19 on patients with chronic liver disease (CLD) and liver transplant recipients.

RECENT FINDINGS

Abnormal liver chemistries occur in up to 60% of COVID-19 patients and are typically mild. COVID-19- associated liver injury may be because of direct viral cytopathic effect, immune-mediated damage, hypoxia, drug-induced liver injury (DILI), or exacerbation of CLD. COVID-19 patients with CLD and who are liver transplant recipients are at risk for severe disease and mortality. COVID-19 precipitated hepatic decompensation in 20-46% of cirrhotic patients. Alcohol consumption and cases of acute alcohol- associated hepatitis increased during the COVID-19 pandemic. Corticosteroids and calcineurin inhibitors are well tolerated to use during COVID-19 but immunomodulators have been associated with mortality. Less than 50% of transplant recipients produce adequate antibody titers after COVID-19 vaccination.

SUMMARY

COVID-19 patients with CLD should be monitored for liver injury and hepatic decompensation. Patients with CLD and liver transplant recipients should be considered for targeted COVID-19 pharmacotherapeutics and advised vaccination against COVID-19, including a third booster dose. CLD treatments and immunosuppression in liver transplant recipients could generally continue without interruption during COVID-19 infection, with the possible exception of immunomodulators.

Risk Prediction Models for Postoperative Decompensation and Infection in Patients With Cirrhosis: A Veterans Affairs Cohort Study

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.

Impact of the COVID-19 Pandemic on Hospitalizations for Alcoholic Hepatitis or Cirrhosis in Alberta, Canada

BACKGROUND & AIMS

Coronavirus disease 2019 (COVID-19) pandemic lockdown and restrictions had significant disruption to patient care. We aimed to evaluate the impact of COVID-19 restrictions on hospitalizations of patients with alcoholic and nonalcoholic cirrhosis as well as alcoholic hepatitis (AH) in Alberta, Canada.

METHODS

We used validated International Classification of Diseases (ICD-9 and ICD-10) coding algorithms to identify liver-related hospitalizations for nonalcoholic cirrhosis, alcoholic cirrhosis, and AH in the province of Alberta between March 2018 and September 2020. We used the provincial inpatient discharge and laboratory databases to identify our cohorts. We used elevated alanine aminotransferase or aspartate aminotransferase, elevated international normalized ratio, or bilirubin to identify AH patients. We compared COVID-19 restrictions (April-September 2020) with prior study periods. Joinpoint regression was used to evaluate the temporal trends among the 3 cohorts.

RESULTS

We identified 2916 hospitalizations for nonalcoholic cirrhosis, 2318 hospitalizations for alcoholic cirrhosis, and 1408 AH hospitalizations during our study time. The in-hospital mortality rate was stable in relation to the pandemic for alcoholic cirrhosis and AH. However, nonalcoholic cirrhosis patients had lower in-hospital mortality rate after March 2020 (8.5% vs 11.5%; P = .033). There was a significant increase in average monthly admissions in the AH cohort (22.1/10,000 admissions during the pandemic vs 11.6/10,000 admissions before March 2020; P < .001).

CONCLUSIONS

Before and during COVID-19 monthly admission rates were stable for nonalcoholic and alcoholic cirrhosis; however, there was a significant increase in AH admissions. Because alcohol sales surged during the pandemic, future impact on alcoholic liver disease could be detrimental.

Rates of timely paracentesis for patients admitted to hospital with cirrhosis and ascites remain low but are unaffected by the COVID-19 pandemic

For the first 6 months of the novel coronavirus-19 (COVID-19) pandemic, the hospital medicine procedure service at our center was temporarily unavailable. We assessed paracentesis rates and clinical outcomes for patients admitted with cirrhosis and ascites before and during the COVID-19 pandemic. Two hundred and twenty-four and 131 patients with cirrhosis and ascited were admitted to hospital before and during COVID-19 respectively. Approximately 50.9% and 49.6% of patients underwent a paracentesis within 24 h pre- and mid-pandemic, p = .83. No differences were observed for length-of-stay or 30-day readmissions. GI consultation was associated with higher rates of paracentesis in both eras (p < .001 pre-COVID-19, and p = .01 COVID-19). Changes due to the COVID-19 pandemic did not result in changes to rates of timely paracentesis in patients admitted with cirrhosis and ascites. While involvement of gastroenterology may increase rates of paracentesis, further efforts are needed to optimize rates of timely paracentesis to positively impact clinical outcomes.

Shifts in inpatient psychiatry utilization patterns at a U.S. Academic Medical Center during the COVID-19 pandemic

The COVID-19 pandemic has impacted utilization volumes and patterns for inpatient psychiatry, though reports have noted inconsistencies on small populations. We obtained demographic and diagnostic data from a retrospective cohort of admitted psychiatric patients at a single-site from March-July 2020 and the corresponding months in 2019. Despite controlling for the modest decrease in inpatient admissions, no statistically significant changes in demographics or utilization was found, except for an increase in patients with substance use disorder (p<0.001). These early findings highlight the demand and necessity for inpatient psychiatry services even during the first COVID-19 spike.

Effect of COVID-19 on presentations of decompensated liver disease in Scotland

BACKGROUND AND AIMS

SARS-CoV-2 and consequent pandemic has presented unique challenges. Beyond the direct COVID-related mortality in those with liver disease, we sought to determine the effect of lockdown on people with liver disease in Scotland. The effect of lockdown on those with alcohol-related disease is of interest; and whether there were associated implications for a change in alcohol intake and consequent presentations with decompensated disease.

METHODS

We performed a retrospective analysis of patients admitted to seven Scottish hospitals with a history of liver disease between 1 April and 30 April 2020 and compared across the same time in 2017, 2018 and 2019. We also repeated an intermediate assessment based on a single centre to examine for delayed effects between 1 April and 31 July 2020.

RESULTS

We found that results and outcomes for patients admitted in 2020 were similar to those in previous years in terms of morbidity, mortality, and length of stay. In the Scotland-wide cohort: admission MELD (Model for End-stage Liver Disease) (16 (12-22) vs 15 (12-19); p=0.141), inpatient mortality ((10.9% vs 8.6%); p=0.499) and length of stay (8 days (4-15) vs 7 days (4-13); p=0.140). In the Edinburgh cohort: admission MELD (17 (12-23) vs 17 (13-21); p=0.805), inpatient mortality ((13.7% vs 10.1%; p=0.373) and length of stay (7 days (4-14) vs 7 days (3.5-14); p=0.525)).

CONCLUSION

This assessment of immediate and medium-term lockdown impacts on those with chronic liver disease suggested a minimal effect on the presentation of decompensated liver disease to secondary care.

The Impact of the COVID-19 Pandemic on Burn Admissions at a Major Metropolitan Burn Center

The impact of the coronavirus disease 2019 (COVID-19) pandemic on admission patterns and outcomes at a burn center is still largely unknown. The aim of this study was to determine how the COVID-19 pandemic affected the epidemiology of burn admissions at a major metropolitan burn center. This retrospective cohort study examined how the COVID-19 pandemic affected burn volumes and time to presentation. All burn admissions were included from January 20 to August 31 for the years 2020, 2019, and 2018. The COVID-19 pandemic group included admissions from January 20, 2020 to August 31, 2020 and was compared to the nonpandemic group comprised of admissions from January 20 to August 31 in 2018 and 2019. Subgroup analysis was performed according to meaningful dates during the COVID-19 pandemic including the first U.S. COVID-19 case, shelter-in-place, and state reopening orders. Admission volumes were 403 patients in the COVID-19 pandemic group compared to a mean of 429 patients in the nonpandemic group, which correlated to a 5.8% decrease in volume during the pandemic. The pandemic group showed an increase in time to presentation of 1 day (P < .0001). Subgroup analysis demonstrated stable admission volumes and an increase in time to presentation of 1 day (P < .0001) at each time point. During shelter-in-place orders, there were higher rates of second/third-degree burns and operative burns (94.7 vs 56.3% and 45.6 vs 27%, P < .0001, P = .013). During the pandemic, there were stable admission volumes, delayed time to admission, and an increase in operative burns during shelter-in-place orders. This reinforces the need to maintain appropriate burn center staffing and resources during the COVID-19 pandemic.

The impact of COVID-19 pandemic on AMI and stroke mortality in Lombardy: Evidence from the epicenter of the pandemic

BACKGROUND

The first Covid-19 epidemic outbreak has enormously impacted the delivery of clinical healthcare and hospital management practices in most of the hospitals around the world. In this context, it is important to assess whether the clinical management of non-Covid patients has not been compromised. Among non-Covid cases, patients with Acute Myocardial Infarction (AMI) and stroke need non-deferrable emergency care and are the natural candidates to be studied. Preliminary evidence suggests that the time from onset of symptoms to emergency department (ED) presentation has significantly increased in Covid-19 times as well as the 30-day mortality and in-hospital mortality.

METHODS

We check, in a causal inference framework, the causal effect of the hospital's stress generated by Covid-19 pandemic on in-hospital mortality rates (primary end-point of the study) of AMI and stroke over several time-windows of 15-days around the implementation date of the State of Emergency restrictions for COVID-19 (March, 9th 2020) using two quasi-experimental approaches, regression-discontinuity design (RDD) and difference-in-regression-discontinuity (DRD) designs. Data are drawn from Spedali Civili of Brescia, one of the most hit provinces in Italy by Covid-19 during March and May 2020.

FINDINGS

Despite the potential adverse effects on expected mortality due to a longer time to hospitalization and staff extra-burden generated by the first wave of Covid-19, the AMI and stroke mortality rates are overall not statistically different during the first wave of Covid-19 than before the first peak. The obtained results provided by RDD models are robust also when we account for seasonality and unobserved factors with DRD models.

INTERPRETATION

The non-statistically significant impact on mortality rates for AMI and stroke patients provides evidence of the hospital ability to manage -with the implementation of a dual track organization- the simultaneous delivery of high-quality cares to both Covid and non-Covid patients.

Correct use of telemedicine in gastroenterology, hepatology, and endoscopy during and after the COVID-19 pandemic: Recommendations from the Italian association of hospital gastroenterologists and endoscopists (AIGO)

The purpose of the present document is to provide detailed information on the correct and optimal use of digital media to ensure continuity of care for gastroenterological patients in everyday clinical practice, in health emergencies and/or when the patient cannot reach the hospital for other reasons. During the recent COVID-19 pandemic, telemedicine has allowed many patients with chronic diseases to access remote care worldwide, proving to be the ideal solution to overcome restrictions and carry out non-urgent routine follow-ups on chronic patients. The COVID-19 pandemic has therefore made organizational and cultural renewal essential for the reorganization of healthcare in order to ensure greater continuity of care with a minimum risk of spreading the virus to users, practitioners and their families. These AIGO recommendations are intended to provide Italian gastroenterologists with a tool to use this method appropriately, in compliance with current legislation, in particular the proper approach and procedures for conducting a remote examination using a video conferencing tool, the so-called televisit. In the near future, telemedicine may contribute to a possible reorganization of healthcare systems, through innovative care models focusing on the citizen and facilitating access to services throughout the entire Country.

Impact of the COVID-19 pandemic on patients with liver cirrhosis-the experience of a tertiary center in Germany

BACKGROUND

The COVID-19 pandemic has caused a significant impact on the medical care of many diseases and has led to reduced presentations to the emergency department. Reduced presentations may be due to overwhelmed capacities of hospitals or collateral damage from fear of infection, lockdown regulations, or other reasons. The effect on patients with liver cirrhosis is not established.

OBJECTIVE

We aim to assess the impact on the care of patients with liver cirrhosis in a tertiary center in Northern Germany.

METHODS

All patients presenting to the emergency department with a diagnosis of cirrhosis between March 1 and May 31 from 2015-2020 were included. Reasons for presentation, duration of symptoms, the severity of liver disease, and 30-day mortality were assessed and compared between patients presenting during the COVID-19 pandemic and pre-COVID-19.

RESULTS

Overall, 235 patients were included. Despite an overall decline in presentations to the emergency department by 11.7%, the frequency of patients presenting with liver cirrhosis has remained stable (non-significant increase by 19.5%). No significant difference could be detected for the MELD score, the CLIF-organ failure subscores, and the 30-day mortality before and during the COVID-19 pandemic. Up to 75% of patients with liver cirrhosis had symptoms >24 h before presenting to the emergency department.

CONCLUSION

Despite the overall trend of reduced emergency presentations during the COVID-19 pandemic, the frequency of presentations of patients with liver cirrhosis did not decline. Morbidity and mortality were not affected in a setting of disposable healthcare resources. The late presentation to the emergency department in many cirrhotic patients may open opportunities for interventions (i.e., with early telemedicine intervention).

Alcohol-Associated Liver Disease Before and After COVID-19-An Overview and Call for Ongoing Investigation

The Coronavirus Disease 2019 (COVID-19) pandemic has exacted a heavy toll on patients with alcohol-associated liver disease (ALD) and alcohol use disorder (AUD). The collective burden of ALD and AUD was large and growing, even before the COVID-19 pandemic. There is accumulating evidence that this pandemic has had a large direct effect on these patients and is likely to produce indirect effects through delays in care, psychological strain, and increased alcohol use. Now a year into the pandemic, it is important that clinicians fully understand the effects of the COVID-19 pandemic on patients with ALD and AUD. To fill existing gaps in knowledge, the scientific community must set research priorities for patients with ALD regarding their risk of COVID-19, prevention/treatment of COVID-19, changes in alcohol use during the pandemic, best use of AUD treatments in the COVID-19 era, and downstream effects of this pandemic on ALD. Conclusion: The COVID-19 pandemic has already inflicted disproportionate harms on patients with ALD, and ongoing, focused research efforts will be critical to better understand the direct and collateral effects of this pandemic on ALD.

Strategies to Improve Delivery of Cirrhosis Care

Purpose of review

This review provides an overview of the current state of research around improving healthcare delivery for patients with cirrhosis in the outpatient, inpatient, and transitional care settings.

Recent findings

Recent studies have broadly employed changes to the model of care delivery, team composition, and technology to improve cirrhosis care. In the outpatient setting, approaches have included engaging caregivers, patient navigators, and non-physicians and using virtual care, smartphone applications, and wearables. Inpatient care approaches have focused on the role of interdisciplinary teams, education interventions, and changes to the medical record system, while post-discharge interventions have included day hospitals and care coordinator interventions. This review also describes the Veterans Health Administration's novel, population-level approach to delivery of cirrhosis care, and addressed how the pandemic has impacted the delivery of cirrhosis care.

Summary

Comprehensive, evidence-based approaches to delivering high-quality cirrhosis care continue to evolve to meet the needs of a growing population in an ever-changing healthcare environment.

Health, work, and contributing factors on life satisfaction: A study in Norway before and during the COVID-19 pandemic

Background

The COVID-19 outbreak has posed considerable challenges for people's health, work situations and life satisfaction. This article reports on a study of the relationship between self-reported health and life satisfaction before and during the COVID-19 pandemic in Norway, and examines the role of work in explaining the health-life satisfaction relationship.

Method

The study was based on survey data collected from 3185 Norwegian employees in 2019 and 3002 employees in 2020. Propensity score matching techniques were used to assess the mediating effects of work situations and income loss on the health-life satisfaction relationship. Skew-t regression models were further applied to estimate changes in life satisfaction before and during the pandemic, as well as to explore different underlying mechanisms for the health-life satisfaction association.

Results

The study found a negative association between ill health and life satisfaction. Compared to the healthy population, people with poor health were more likely to experience worsened work situations. A negative work situation is further associated with lower life satisfaction, and the pandemic aggravated life satisfaction for those who had worsened work situations. When exploring central contributing factors for life satisfaction, we found that health-related risks and work-life balance played predominant roles in predicting life satisfaction before the pandemic, while different types of household structure were among the most important predictors of life satisfaction during the pandemic.

Conclusion

A reduction in life satisfaction is explained by ill health, but different underlying mechanisms facilitated people's life satisfaction before and during the pandemic. While work situation and health risks were important predictors for life satisfaction in 2019, worries about more unstable work situations and less access to family support accentuated worsened life satisfaction in 2020. The findings suggest the necessity of labour market interventions that address the security and maintenance of proper and predictable work situations, especially in these more uncertain times.

COVID-19 and liver disease: mechanistic and clinical perspectives

Our understanding of the hepatic consequences of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and its resultant coronavirus disease 2019 (COVID-19) has evolved rapidly since the onset of the pandemic. In this Review, we discuss the hepatotropism of SARS-CoV-2, including the differential expression of viral receptors on liver cell types, and we describe the liver histology features present in patients with COVID-19. We also provide an overview of the pattern and relevance of abnormal liver biochemistry during COVID-19 and present the possible underlying direct and indirect mechanisms for liver injury. Furthermore, large international cohorts have been able to characterize the disease course of COVID-19 in patients with pre-existing chronic liver disease. Patients with cirrhosis have particularly high rates of hepatic decompensation and death following SARS-CoV-2 infection and we outline hypotheses to explain these findings, including the possible role of cirrhosis-associated immune dysfunction. This finding contrasts with outcome data in pharmacologically immunosuppressed patients after liver transplantation who seem to have comparatively better outcomes from COVID-19 than those with advanced liver disease. Finally, we discuss the approach to SARS-CoV-2 vaccination in patients with cirrhosis and after liver transplantation and predict how changes in social behaviours and clinical care pathways during the pandemic might lead to increased liver disease incidence and severity.

Frailty Is a Risk Factor for Postoperative Mortality in Patients With Cirrhosis Undergoing Diverse Major Surgeries

With a rising burden of cirrhosis surgeries, understanding risk factors for postoperative mortality is more salient than ever. The role of baseline frailty has not been assessed in this context. We evaluated the association between patient frailty and postoperative risk among diverse patients with cirrhosis and determined if frailty improves prognostication of cirrhosis surgical risk scores. This was a retrospective cohort study of U.S. veterans with cirrhosis identified between 2008 and 2016 who underwent nontransplant major surgery. Frailty was ascertained using the Hospital Frailty Risk Score (HFRS). Cox regression analysis was used to investigate the impact of patient frailty on postoperative mortality. Logistic regression was used to identify incremental changes in discrimination for postoperative mortality when frailty was added to the risk prediction models, including the Model for End-Stage Liver Disease (MELD), MELD-sodium (MELD-Na), Child-Turcotte-Pugh (CTP), Mayo Risk Score (MRS), and Veterans Outcomes and Costs Associated With Liver Disease (VOCAL)-Penn. A total of 804 cirrhosis surgeries were identified. The majority of patients (48.5%) had high-risk frailty at baseline (HFRS >15). In adjusted Cox regression models, categories of increasing frailty scores were associated with poorer postoperative survival. For example, intermediate-risk frailty (HFRS 5-15) conferred a 1.77-fold increased hazard relative to low-risk frailty (HFRS, <5; 95% confidence interval [CI], 1.06-2.95; P = 0.03). High-risk frailty demonstrated a similarly increased hazard (hazard ratio, 1.74; 95% CI, 1.05-2.88; P = 0.03), suggesting a threshold effect of frailty on postoperative mortality. The incorporation of frailty improved discrimination of MELD, MELD-Na, and CTP for postoperative mortality, but did not do so for the MRS or VOCAL-Penn score. Patient frailty was an additional important predictor of cirrhosis surgical risk. The incorporation of preoperative frailty assessments may help to risk stratify patients, especially in settings where the MELD-Na and CTP are commonly applied.
