The Burden of Rehospitalization for Patients With Liver Cirrhosis

Trends in the burden of hospitalised patients with cirrhosis in Switzerland: a cross-sectional study of cirrhosis-related hospitalisations between 1998 and 2020

OBJECTIVE

Liver cirrhosis is an increasing cause of morbidity and mortality worldwide with a heavy load on healthcare systems. We analysed the trends in hospitalisations for cirrhosis in Switzerland.

DESIGN

Cross-sectional study.

SETTING

Large nationwide inpatient database, years between 1998 and 2020.

PARTICIPANTS

Hospitalisations for cirrhosis of adult patients were selected.

MAIN OUTCOMES AND MEASURES

Hospitalisations with either a primary diagnosis of cirrhosis or a cirrhosis-related primary diagnosis with a mandatory presence of cirrhosis as a secondary diagnosis were considered following the 10th revision of the International Statistical Classification of Diseases and Related Health Problems codes. Trends in demographic and clinical characteristics, in-hospital mortality and length of stay were analysed. Causes and costs of cirrhosis-related hospitalisations were available from 2012 onwards.

RESULTS

Cirrhosis-related hospitalisations increased from 1631 in 1998 to 4052 in 2020. Of the patients, 68.7% were men. Alcohol-related liver disease was the leading cause, increasing from 44.1% (95% CI, 42.4% to 45.9%) in 2012 to 47.9% (95% CI, 46.4% to 49.5%) in 2020. Assessed by exclusion of other coded causes, non-alcoholic fatty liver disease was the second cause at 42.7% (95% CI, 41.2% to 44.3%) in 2020. Hepatitis C virus-related cirrhosis decreased from 12.3% (95% CI, 11.2% to 13.5%) in 2012 to 3.2% (95% CI, 2.7% to 3.8%) in 2020. Median length of stay decreased from 11 to 8 days. Hospitalisations with an intensive care unit stay increased from 9.8% (95% CI, 8.4% to 11.4%) to 15.6% (95% CI, 14.5% to 16.8%). In-hospital mortality decreased from 12.1% (95% CI, 10.5% to 13.8%) to 9.7% (95% CI, 8.8% to 10.7%). Total costs increased from 54.4 million US$ (51.4 million €) in 2012 to 92.6 million US$ (87.5 million €) in 2020.

CONCLUSIONS

Cirrhosis-related hospitalisations and related costs increased in Switzerland from 1998 to 2020 but in-hospital mortality decreased. Alcohol-related liver disease and non-alcoholic fatty liver disease were the most prevalent and preventable aetiologies of cirrhosis-related hospitalisations.

A randomized controlled trial of a postdischarge nursing intervention for patients with decompensated cirrhosis

BACKGROUND

Few randomized trials have evaluated the effect of postdischarge interventions for patients with liver cirrhosis. This study assessed the effects of a postdischarge intervention on readmissions and mortality in patients with decompensated liver cirrhosis.

METHODS

We conducted a randomized controlled trial at a specialized liver unit. Adult patients admitted with complications of liver cirrhosis were eligible for inclusion. Participants were allocated 1:1 to standard follow-up or a family-focused nurse-led postdischarge intervention between December 1, 2019, and October 31, 2021. The 6-month intervention consisted of a patient pamphlet, 3 home visits, and 3 follow-up telephone calls by a specialized liver nurse. The primary outcome was the number of readmissions due to liver cirrhosis.

RESULTS

Of the 110 included participants, 93% had alcohol as a primary etiology. We found no significant differences in effects in the primary outcomes such as time to first readmission, number of patients readmitted, and duration of readmissions or in the secondary outcomes like health-related quality of life and 6- and 12-month mortality. A post hoc exploratory analysis showed a significant reduction in nonattendance rates in the intervention group (RR: 0.28, 95% CI: 0.13-0.54, p=0.0004) and significantly fewer participants continuing to consume alcohol in the intervention group (p=0.003). After 12 months, the total number of readmissions (RR: 0.76, 95% CI: 0.59-0.96, p=0.02) and liver-related readmissions (RR: 0.55, 95% CI: 0.36-0.82, p=0.003) were reduced in the intervention group.

CONCLUSIONS

A family-focused postdischarge nursing intervention had no significant effects on any of the primary or secondary outcomes. In a post hoc exploratory analysis, we found reduced 6-month nonattendance and alcohol consumption rates, as well as reduced 12-month readmission rates in the intervention group.

Risk factors for hospital readmission among patients with cirrhosis and ascites in China: a retrospective observational study

OBJECTIVE

In this investigation, we aimed to explore risk factors for 90-day hospital readmission among patients with cirrhosis and ascites in an Asian population.

METHODS

In this retrospective study, we included consecutive patients diagnosed with cirrhosis and ascites hospitalized in Renji Hospital between 2018 and 2022 to elucidate risk factors for 90-day readmission. We conducted multivariate logistic regression analysis to identify readmission risk factors.

RESULTS

We included 265 patients with cirrhosis and ascites. A 43% readmission rate was observed within 90 days. After adjustment for multiple covariates, we found that readmission within 90 days was independently linked to reduced levels of hemoglobin (odds ratio [OR] 0.96, 95% confidence interval [CI] 0.94-0.97) and serum albumin (OR 0.88, 95% CI 0.83-0.93), and higher Model for End-Stage Liver Disease and sodium (MELD-Na) scores (OR 1.04, 95% CI 1.01-1.07) at discharge.

CONCLUSIONS

Patients with cirrhosis who have ascites are frequently rehospitalized within 90 days after discharge. Lower hemoglobin or albumin and higher MELD-Na scores at discharge may be the main risk factors for hospital readmission.

Measuring Medication Use, Obstacles, and Knowledge in Individuals With Cirrhosis

BACKGROUND & AIMS

Although patient knowledge is modifiable, there are no widely accepted tools to measure patient understanding during cirrhosis care. We aimed to develop and validate "My Cirrhosis Coach" (MCC), a personalized, self-administered questionnaire to evaluate cirrhosis-related medication use, obstacles, and understanding.

METHODS

Adults with cirrhosis were prospectively enrolled at 3 tertiary centers from July 2016 through July 2020. Psychometrics including confirmatory factor analysis was used to develop and validate a final questionnaire. Content validity was measured via the content validity index and expert performance. Discriminant validity was assessed by comparing scores between groups hypothesized to have varying performance.

RESULTS

The MCC was tested in a diverse cohort (n = 713) with cirrhosis and its complications including ascites (45%) and hepatic encephalopathy (33%) with median Model for End-Stage Liver Disease-Sodium 10 (interquartile range, 9-15). A 6-factor model of the MCC fit the data well (root mean square error of approximation, 0.22; comparative fit index, 0.96; standardized root mean squared residual, 0.104; final domains: Medication Use & Accessibility, Medication Obstacles, Lactulose Use, Diuretic Use, Beta Blocker Use, and Dietary Sodium Use). The MCC had excellent content validity (content validity index, 81%-94%) and accuracy (91%-100%) ratings by experts. Mean domain scores ranged from 1.1 to 2.6 (range, 0-3; 3 indicating better performance). Those with a cirrhosis complication scored higher in the relevant medication domain (ie, diuretic use score in ascites). Compared with outpatients, inpatients scored higher in all knowledge domains except salt use and reported more medication obstacles. Scores differed by income, education level, and having an adult at home.

CONCLUSIONS

In a large, diverse cohort, we validated the MCC, which can serve to standardize medication use and knowledge measurement in clinical practice and education-based studies in cirrhosis.

Confusion assessment method accurately screens for hepatic encephalopathy and predicts short-term mortality in hospitalized patients with cirrhosis

Hepatic encephalopathy (HE), a subtype of delirium, is common in cirrhosis and associated with poor outcomes. Yet, objective bedside screening tools for HE are lacking. We examined the relationship between an established screening tool for delirium, Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) and short-term outcomes while comparing its performance with previously established measures of cognitive function such as West Haven criteria (WHC). Prospectively enrolled adults with cirrhosis who completed the CAM-ICU from 6/2014-6/2018 were followed for 90 days. Blinded provider-assigned West Haven Criteria (WHC) and other measures of cognitive function were collected. Logistic regression was used to test associations between CAM-ICU status and outcomes. Mortality prediction by CAM-ICU status was assessed using Area under the Receiver Operating Characteristics curves (AUROC). Of 469 participants, 11% were CAM-ICU( +), 55% were male and 94% were White. Most patients were Childs-Pugh class C (59%). CAM-ICU had excellent agreement with WHC (Kappa = 0.79). CAM-ICU( +) participants had similar demographic features to those CAM-ICU(-), but had higher MELD (25 vs. 19, p < 0.0001), were more often admitted to the ICU (28% vs. 7%, p < 0.0001), and were more likely to be admitted for HE and infection. CAM-ICU( +) participants had higher mortality (inpatient:37% vs. 3%, 30-day:51% vs. 11%, 90-day:63% vs. 23%, p < 0.001). CAM-ICU status predicted mortality with AUROC of 0.85, 0.82 and 0.77 for inpatient, 30-day and 90-day mortality, respectively. CAM-ICU easily screens for delirium/HE, has excellent agreement with WHC, and identifies a hospitalized cirrhosis cohort with high short-term mortality.

A Nurse-Led Outpatient Clinic for Patients With Decompensated Liver Cirrhosis: Staffing, Structure, and Patient Satisfaction

Patients with decompensated liver cirrhosis constitute a growing and vulnerable patient group with a particular need for easy outpatient access and close follow-up. By establishing a nurse-led clinic, we aimed to counter this need in a patient-centered manner within a multidisciplinary rehabilitating framework. This article presents the organization, staffing, and structure of this initiative as well as the patient population demographics and characteristics. Furthermore, patient satisfaction within the clinic was explored. Two complementary substudies are presented: a descriptive, registry-based journal audit, presenting data from the clinic's first years, 2017-2019, and a cross-sectional, descriptive survey, exploring patient satisfaction 2 years later. Different visit types with predefined content constitute an operable structure suitable for meeting patients' current needs. An increase in both the number of patients and visits from the first to second years indicates an existing need for nurse-led support. Data not only support the well-known characteristics of patients with cirrhosis but also add to a broader perspective with more nuances for this patient population. The survey shows an overall high score on satisfaction but also points out areas for improvement. The nurse-led clinic provides both structure and knowledge to facilitate patient-centered treatment and care for those suffering from liver cirrhosis.

Old age promotes retinal fibrosis in choroidal neovascularization through circulating fibrocytes and profibrotic macrophages

BACKGROUND

Retinal fibrosis affects 40-70% of neovascular age-related macular degeneration patients. This study investigated the effect of ageing on subretinal fibrosis secondary to choroidal neovascularization and the mechanism of action.

METHODS

Subretinal fibrosis was induced in young (2.5-month) and aged (15-16-month) C57BL/6J mice using the two-stage laser protocol. Five and 30 days later, eyes were collected and stained for CD45 and collagen-1 and observed by confocal microscopy. Fibrocytes (CD45+collagen-1+) were detected in the bone marrow (BM), blood and fibrotic lesions by flow cytometry and confocal microscopy, respectively. BM-derived macrophages (BMDMs) were cultured from young and aged mice with or without TGF-β1 (10 ng/mL) treatment. The expression of mesenchymal marker αSMA (Acta2), fibronectin (Fn1) and collagen-1 (Col1a1) was examined by qPCR and immunocytochemistry, whereas cytokine/chemokine production was measured using the Luminex multiplex cytokine assay. BM were transplanted from 22-month (Ly5.2) aged mice into 2.5-month (Ly5.1) young mice and vice versa. Six weeks later, subretinal fibrosis was induced in recipient mice and eyes were collected for evaluation of fibrotic lesion size.

RESULTS

Under normal conditions, the number of circulating fibrocytes (CD45+collagen-1+) and the expression levels of Tgfb1, Col1a1, Acta2 and Fn1 in BMDMs were significantly higher in aged mice compared to young mice. Induction of subretinal fibrosis significantly increased the number of circulating fibrocytes, enhanced the expression of Col1a1, Acta2 and Fn1 and the production of soluble urokinase plasminogen activator surface receptor (suPAR) but decreased the production of CXCL10 in BMDMs. BMDMs from aged subretinal fibrosis mice produced significantly higher levels of VEGF, angiopoietin-2 and osteopontin than cells from young subretinal fibrosis mice. The subretinal fibrotic lesion in 15-16-month aged mice was 62% larger than that in 2.5-month young mice. The lesion in aged mice contained a significantly higher number of fibrocytes compared to that in young mice. The number of circulating fibrocytes positively correlated with the size of subretinal fibrotic lesion. Transplantation of BM from aged mice significantly increased subretinal fibrosis in young mice.

CONCLUSIONS

A retina-BM-blood-retina pathway of fibrocyte/macrophage recruitment exists during retinal injury. Ageing promotes subretinal fibrosis through higher numbers of circulating fibrocytes and profibrotic potential of BM-derived macrophages.

Incidence and predictors of 30-day hospital readmissions for liver cirrhosis: insights from the United States National Readmissions Database

Background

Cirrhosis is associated with substantial inpatient morbidity and mortality. This study aimed to determine the trends in 30-day hospital readmission rates among patients with cirrhosis and identify factors associated with these readmissions.

Methods

We conducted a retrospective analysis of data retrieved from the Nationwide Readmissions Database to determine trends in 30-day readmission for patients discharged with a diagnosis of cirrhosis in 2010 through 2014. Multivariate logistic regression analysis was used to identify predictors of readmission.

Results

Among 303,346 patients identified from the database, the 30-day readmission rate for patients with a discharge diagnosis of cirrhosis was 31.4% (n=95,298). The trends in the readmission rates remained steady during the study period. On multivariate analysis, female sex, age 45 years or older, esophagogastroduodenoscopy (EGD) during admission, and disposition to a short-term care facility or skilled nursing facility protected against readmissions. In contrast, coverage by Medicaid insurance, admission during a weekend, nonalcoholic cause of cirrhosis, and history of hepatic encephalopathy and ascites were associated with readmission.

Conclusions

We found an exceptionally high 30-day readmission rate in patients with cirrhosis, although it remained stable during the study period. This study identified some modifiable factors such as disposition to a short-term care facility or skilled nursing facility and patients’ attendance of alcohol rehabilitation facilities that could decrease the likelihood of readmission and could inform local and national healthcare policymakers.

Lower household income is associated with an increased risk of hospital readmission in patients with decompensated cirrhosis

BACKGROUND AND AIM

The impact of household income, a surrogate of socioeconomic status, on hospital readmission rates for patients with decompensated cirrhosis has not been well characterized.

METHODS

The Nationwide Readmission Database from 2012 to 2014 was used to study the association of lower median household income on 30-, 90-, and 180-day hospital readmission rates for patients with decompensated cirrhosis.

RESULTS

From the 42 679 001 hospital admissions contained in the sample, there were 82 598 patients with decompensated cirrhosis who survived a hospital admission in the first 6 months of the year. During a uniform 6-month follow-up period, 25 914 (31.4%), 39 928 (48.3%), and 47 496 (57.5%) patients were readmitted at 30, 90, and 180 days, respectively. After controlling for demographic and clinical confounders, patients residing in the three lowest income quartiles were significantly more likely to be readmitted at 30 days than those in the fourth quartile (first quartile, odds ratio [OR] 1.32 [95% confidence interval, CI, 1.17-1.47, P < 0.01]; second quartile, OR 1.25 [95% CI 1.13-1.38, P < 0.01]; and third quartile, OR 1.08 [95% CI 0.97-1.20, P = 0.07]). The association between lower socioeconomic status and the higher risk of readmissions persisted at 90 days (first quartile, OR 1.21 [95% CI 1.14-1.30, P < 0.01]) and 180 days (first quartile, OR 1.32 [95% CI 1.20-1.44, P < 0.01]).

CONCLUSION

Patients with decompensated cirrhosis residing in the lowest income quartile had a 32% higher odds of hospital readmissions at 30, 90, and 180 days compared with those in the highest income quartile.

The Health Care Burden of Hepatic Encephalopathy

Hepatic encephalopathy is a major neuropsychiatric complication of liver disease that affects 30% to 40% of cirrhotic patients. Hepatic encephalopathy is characterized by a brain dysfunction that is associated with neurologic complications. Those complications are associated with cognitive impairments, which negatively impacts patients' physical and mental health. In turn, hepatic encephalopathy poses a substantial economic and use burdens to the health care system. This article reviews the multidimensional aspects of the health care burden posed by hepatic encephalopathy.

Palliative Care and Hospice Referrals in Patients with Decompensated Cirrhosis: What Factors Are Important?

Background: Palliative care (PC) and hospice care are underutilized for patients with end-stage liver disease, but factors associated with these patterns of utilization are not well understood. Objective: We examined patient-level factors associated with both PC and hospice referrals in patients with decompensated cirrhosis (DC). Design: Retrospective cohort study. Setting/Subjects: Patients with DC hospitalized at a single tertiary center and followed for one year. Measurements: We assessed PC and hospice referrals during follow-up and examined patient-level factors associated with the receipt of PC and/or hospice, as well as associated clinical outcomes. We also examined late referrals (within one week of death). Results: Of 397 patients, 61 (15.4%) were referred to PC, 71 (17.9%) were referred to hospice, and 99 (24.9%) were referred to PC and/or hospice. Two hundred patients (50.4%) died during the one-year follow-up. In multivariable logistic regression, referral to PC was associated with increased comorbidity burden, ascites, increased MELD (Model for End-Stage Liver Disease)-Na score, lack of listing for liver transplant, and unmarried status. Hospice referral was associated with increased comorbidities, portal vein thrombosis, and hepatocellular carcinoma. PC referrals were late in 68.5% of cases, and hospice referrals were late in 62.7%. Late PC referrals were associated with younger age and married status. Late hospice referrals were associated with younger age and recent alcohol use. Conclusions: PC and hospice is underutilized in patients with DC, and most referrals are late. Patient-level factors associated with these referrals differ between PC and hospice.

Association of Helicobacter pylori with the Risk of Hepatic Encephalopathy

BACKGROUND/OBJECTIVES

Hepatic encephalopathy is the common manifestation of decompensated cirrhosis. The association between Helicobacter pylori (H. pylori) infection and hepatic encephalopathy has been shown in many epidemiologic studies. This meta-analysis was conducted to summarize all available studies to estimate the association between H. pylori infection and hepatic encephalopathy.

METHODS

A comprehensive literature review was conducted using MEDLINE and EMBASE database through March 2017 to identify studies that reported the association between H. pylori infection and hepatic encephalopathy. Effect estimates from the individual study were extracted and combined using random-effect, generic inverse variance method of DerSimonian and Laird.

RESULTS

Of 15,233 studies, eleven studies (four cross-sectional, four case-control, and three cohort studies) met the eligibility criteria and were included in the meta-analysis. The pooled OR of hepatic encephalopathy in patients with H. pylori infection was 1.73 (95% CI 1.09-2.73) when compared with the patients without H. pylori infection. The association between H. pylori and hepatic encephalopathy was not statistically significant after the sensitivity analysis, excluding those using ELISA alone, with a pooled OR of 1.92 (95% CI 0.91-4.05, I ² = 62%). There was no publication bias of overall included studies assessed by the funnel plots and Egger's regression asymmetry test.

CONCLUSIONS

This study demonstrated a potential association between H. pylori infection and risk of hepatic encephalopathy. Future studies are required to assess the effect of chronicity of infection on the development of hepatic encephalopathy.

Impact of Cirrhosis on Resource Use and Inpatient Complications in Patients Undergoing Total Knee and Hip Arthroplasty

BACKGROUND

Cirrhosis is a major cause of morbidity and mortality and is an important risk factor for complications in surgical patients. The purpose of this study was to investigate the association of cirrhosis with postoperative complications, length of stay (LOS), and costs among patients who underwent total knee arthroplasty (TKA) or total hip arthroplasty (THA).

METHODS

Using the Nationwide Inpatient Sample between 2000 and 2011, we identified patients who had a primary TKA or primary THA. TKA patients were divided into 2 groups: (1) cirrhosis (n = 41,464) and (2) no cirrhosis (n = 5,721,297) and THA patients were divided into 2 groups: (1) cirrhosis (n = 27,401) and (2) no cirrhosis (n = 2,622,539). Patient demographics, comorbidities, perioperative complications, LOS, and incremental costs were analyzed. An additional subgroup analysis by cirrhosis etiology was performed.

RESULTS

Multivariable analysis revealed cirrhosis was associated with 1.55 (95% confidence interval: 1.47-1.63) times higher odds of any complication after TKA and 1.59 (1.50-1.69) higher odds after THA. Adjusted outcomes showed cirrhotic TKA patients had $1857 higher costs and 0.30 days longer LOS and THA cirrhotic patients had $1497 higher costs and 0.48 longer LOS. We found similar results for each cirrhosis subtype but alcohol-related had the highest resource use and complication rate.

CONCLUSION

Patients with cirrhosis who are undergoing TKA or THA are at a significantly increased risk for perioperative complications, increased LOS, and higher costs. The perioperative complications and costs were highest among patients with alcohol-related cirrhosis.
