In-Hospital Outcomes of Patients with Acute Decompensated Heart Failure and Cirrhosis: An Analysis of the National Inpatient Sample

Outcomes in Acute Decompensated Congestive Heart Failure Admissions with Chronic Liver Disease: A Nationwide Analysis Using the National Inpatient Sample

AIM

The aim of our study was primarily to analyze hospital outcomes for acute decompensated heart failure (ADHF) admissions with a comorbid diagnosis of chronic liver disease (CLD).

METHODS

The NIS was used to select ADHF admissions. The population characteristics of general ADHF admissions were compared with ADHF admissions with a comorbid diagnosis of CLD. Multivariate probit logistic regression was used to analyze the association between a documented diagnosis of CLD/alcoholic liver disease and all-cause mortality in ADHF admissions. Confounders were accounted for. Propensity scoring and nearest neighbor matching were conducted to select a matched cohort with and without CLD from ADHF admissions to further look at mortality outcomes.

RESULTS

ADHF admissions with a comorbid diagnosis of CLD had a significantly higher proportion of all-cause mortality, 0.054 (0.053-0.057), a higher length of hospital stay, 6.95 days (6.84-7.06), and a higher mean of total hospital charges, USD 88,068.1, when compared to ADHF admissions without a comorbid diagnosis of CLD: all-cause mortality, 0.045 (0.044-0.046); length of hospital stay, 6.18 days (6.13-6.23); and mean total hospital charges, USD 79,946.21. A comorbid diagnosis of CLD had a significant association with all-cause mortality in ADHF admissions: OR 1.23 (1.17-1.29) after accounting for confounders. In the propensity-matched cohorts, the cohort with a diagnosis of CLD from the ADHF admissions had a higher proportion of all-cause mortality, 0.042 (0.036-0.049), when compared to the cohort without a diagnosis of chronic liver disease, 0.027 (0.022-0.033).

CONCLUSIONS

In analyzing the mortality and healthcare utilization outcomes for ADHF admissions, the comorbid diagnosis of CLD is shown to have significantly higher all-cause mortality, higher length of hospital stay, and higher mean total charges when compared to ADHF admissions without a diagnosis of CLD. A documented diagnosis of CLD had a statistically significant association with all-cause mortality in ADHF admissions after accounting for confounding factors.

Accuracy and correlation of bed and standing scale weights in monitoring volume status in heart failure patients

Introduction: Accurate volume status monitoring is crucial for effective diuretic therapy in patients with acute decompensated heart failure (ADHF). While guidelines recommend daily standing body weight measurement as an indicator of volume status, bed scales are commonly used in healthcare facilities.Methods: A method-comparison design was used to compare bed and standing scale weights among adults hospitalized with ADHF at Los Angeles County-University of Southern California Medical Center between March and April 2023.Results & Conclusion: Among 51 weight pairs from 43 participants, a clinically significant mean difference of 1.42 ± 1.18 kg was observed, exceeding the recommended threshold. Inaccuracies, with 71% showing differences >0.6 kg, highlight potential fluid management errors when relying on bed scales in ADHF hospitalizations.

Retrospective analyses of the outcomes among hospitalized liver cirrhosis patients with heart failure and COVID-19 infection: Insight from the National Inpatient Sample

Background

There is paucity of data regarding the impact of Coronavirus Disease 2019 (COVID-19) infection on the outcomes of hospitalized liver cirrhosis (LC) patients with heart failure (HF).

Methods

Utilizing the 2020 National Inpatient Sample (NIS) Database, we conducted a retrospective cohort study to investigate the outcomes of hospitalized LC patients with HF and COVID-19 infection, looking at its impact on in-hospital mortality, risk for acute kidney injury (AKI) and length of stay (LOS).

Results

We identified a total of 10,810 hospitalized LC patients with HF, of which 1.39 % (n = 150/10,810) had COVID-19 infection. Using a stepwise survey multivariable logistic regression model that adjusted for patient and hospital level confounders, COVID-19 infection among hospitalized LC patients with HF was found to be an independent predictor of overall in-hospital mortality (aOR 3.73; 95 % CI, 1.58-8.79; p = 0.00) and risk for AKI (aOR 3.06; 95 % CI, 1.27-7.37; p = 0.01) compared to those without COVID-19 infection. However, there were comparable rates of LOS among LC patients with HF regardless of COVID-19 infection status. Moreover, AKI was found to be an independent predictor of longer LOS (coefficient 4.40, 95 % CI 3.26-5.38; p = 0.00). On subgroup analysis, diastolic HF was found to be associated with increased risk for in-hospital mortality (aOR 6.54; 95 % CI, 2.02-21.20; p = 0.00), development of AKI (aOR 3.33; 95 % CI, 1.12-9.91; p = 0.03) and longer LOS (coefficient 4.30, 95 % CI 0.79-9.45; p = 0.03).

Conclusion

Concomitant COVID-19 infection among hospitalized LC patients with HF was associated with higher risk for in-hospital mortality and AKI but did not significantly affect hospital LOS.

Association Between Cirrhosis and 30-Day Rehospitalization After Index Hospitalization for Heart Failure

There are limited data on clinical outcomes in patients re-admitted with decompensated heart failure (HF) with concomitant liver cirrhosis. We conducted a cross sectional analysis of the Nationwide Readmissions Database (NRD) years 2010 thru 2012. An Index admission was defined as a hospitalization for decompensated heart failure among persons aged ≥ 18 years with an alive discharge status. The main outcome was 30 - day all-cause rehospitalization. Survey logistic regression provided the unadjusted and adjusted odds of 30 - day rehospitalization among persons with and without cirrhosis, accounting for age, gender, kidney dysfunction and other comorbidities. There were 2,147,363 heart failure (HF) hospitalizations among which 26,156 (1.2%) had comorbid cirrhosis. Patients with cirrhosis were more likely to have a diagnosis of acute kidney injury (AKI) during their index hospitalization (18.4% vs 15.2%). There were 469,111 (21.9%) patients with readmission within 30 - days. The adjusted odds of a 30 - day readmission was significantly higher among patients with cirrhosis compared to without after adjusting for comorbid conditions (adjusted Odds Ratio [aOR], 1.3; 95% Confidence Interval [CI}: 1.2 to 1.4). The relative risk of 30 - day readmission among those with cirrhosis but without renal disease (aOR, 1.3; 95% CI: 1.3 to 1.3) was lower than those with both cirrhosis and renal disease (aOR, 1.8; 95% CI: 1.6 to 2.0) when compared to persons without either comorbidities. Risk of 30 - day rehospitalization was significantly higher among patients with heart failure and underlying cirrhosis. Concurrent renal dysfunction among patients with cirrhosis hospitalized for decompensated HF was associated with a greater odds of rehospitalization.

In-Hospital Outcomes of Patients With Pulmonary Hypertension and Cirrhosis: A 6-Year Population Cohort Study of Over One Million Patients

INTRODUCTION

There is a paucity of data on the influence of sex, race, insurance, pulmonary hypertension-related complications, and cirrhosis-related complications on mortality, hospital length of stay (LOS), and total hospital charges. The aim of this study was to identify risk factors in a national population cohort (in the USA) admitted to hospital between 2012 and 2017.

METHODS

All patients aged > 18 years with pulmonary hypertension and cirrhosis, who had been admitted to hospital between 2012 and 2017, were identified from the US Nationwide Inpatient Sample (NIS), a large publicly available all-payer inpatient care database in the USA. Multivariate regression analysis was used to estimate the odds ratios of in-hospital mortality, average length of hospital stay, and hospital charges, after adjusting for age, gender, race, primary insurance payer status, hospital type and size (number of beds), hospital region, hospital teaching status, and other demographic characteristics.

RESULTS

Our study identified 1,111,594 patients who had been discharged from hospital from 2012 to 2017. Of these patients, 355,455 were admitted with pulmonary hypertension, with 9.8% having cirrhosis as a complication (n = 34,986). The analysis revealed that patients with both pulmonary hypertension and cirrhosis compared to patients with only pulmonary hypertension experience increased mortality, hospital LOS, total hospital charges, and pulmonary hypertension-related and cirrhosis-related complications. Independent positive predictors of mortality were Asian/Pacific Islander race and "other" insurance status (worker's compensation; other US health benefits plans [CHAMPUS/TRICARE, CHAMPVA, Title V]). Independent positive predictors of increased hospital LOS were black race and "other" patients (more than one race/mixed). Independent positive predictors of increased total hospital charges were male gender, Hispanic ethnicity, Asian/Pacific Islander race, and other insurance status. Pulmonary hypertension-related complications (cor pulmonale, pulmonary embolism, hemoptysis, cardiac arrest, atrial fibrillation, ventricular tachycardia) and cirrhosis-related complications (ascites, hepatorenal syndrome, hepatic encephalopathy, variceal bleeding, portal hypertension) were independent positive predictors of mortality, hospital LOS, and total hospital charges.

CONCLUSIONS

Patients with pulmonary hypertension and cirrhosis have increased mortality and hospital utilization compared to patients with only pulmonary hypertension. We identified key drivers for these outcomes. Targeted interventions, such as novel medications, right-to-left shunts, more evaluations for lung transplantation, and reversal of pulmonary vacular remodeling, are needed for the subgroups identified in this study in order to improve outcomes.
