An observational study of the direct costs related to hospital admissions, mortality and premature death associated with liver disease in Portugal

Prior hospital attendances in deceased Australian patients with alcohol-related liver disease: a multicentre project

BACKGROUND AND AIMS

To establish the hospital visit history of patients who die with alcohol-related liver disease (ArLD). To determine if patients with ArLD present to hospital early or in the terminal phase of their disease.

METHODS

Retrospective cohort study of patients with a history of ArLD who died as an inpatient at three tertiary Western Australian hospitals from February 2015 to February 2017. Hospital records were reviewed to identify the number and cause of emergency department (ED), inpatient and outpatient attendances in all Western Australian public hospitals in the 10 years prior to death.

RESULTS

One hundred fifty-nine patients (23% female) had a total of 753 ED, 3535 outpatient appointments, 1602 hospital admissions and 10 755 admission days. Twelve months prior to death, 82% of patients had a public hospital contact and 74% an admission. Patients who had their first hospital contact within 12 months prior to death were significantly more likely to have a liver-related cause of death (P < 0.01). Aboriginal and Torres Strait Islander patients (15% of cohort) died at a significantly younger age (M = 49.2, SD = 10.5 years) than non-Aboriginal and Torres Strait Islander patients (M = 59.9, SD = 10.2 years, P < 0.01). Despite having more ED attendances and hospital admissions, Aboriginal and Torres Strait Islander patients had significantly less (P = 0.04) outpatient appointments (Mdn = 5.5, interquartile range [IQR] = 1-18 vs Mdn = 11, IQR = 3-33).

CONCLUSIONS

Most patients with ArLD have multiple early attendances, which present an opportunity for early interventions. There are missed opportunities for Aboriginal and Torres Strait Islander patients for outpatient hospital engagement.

Alcohol-associated liver disease: Epidemiology and management

Alcohol is the leading cause of preventable liver morbidity and mortality worldwide, as it is also the most frequent cause of advanced liver disease. Alcohol-associated liver disease (ALD) covers different phenotypes ranging from steatosis to the development of inflammation (steatohepatitis), fibrosis and ultimately, in a proportion of patients, the development of liver cirrhosis and its associated complications. ALD has a complex pathogenesis that includes the interplay of both genetic and environmental factors, yet the precise mechanisms are largely unknown. Alcohol-associated hepatitis (AH) is a severe clinical presentation of ALD, which is characterized by abrupt jaundice and clinical decompensations of liver disease. AH occurs in a percentage of patients with underlying ALD and active alcohol consumption. Currently, there are no approved targeted therapies able to interfere in the pathogenesis of ALD and halt the progression of the disease, therefore alcohol abstinence is the most effective measure to improve prognosis in this patient population. In this regard, alcohol cessation remains the first-line treatment in all stages of alcohol disease. In patients with advanced ALD nonresponding to medical therapy, liver transplantation is the only approach that improves prognosis, and it should be considered in patients with decompensated cirrhosis. In the last years, AH has emerged as a new indication of early liver transplantation in non-responders to medical therapy, with promising results in highly selected patients. In this review, we provide an update on the epidemiology, risk factors, natural history, diagnosis, pathogenesis, and current treatments for ALD, taking into account the importance of assessing and managing alcohol consumption as the etiological factor and the main driver of prognosis in patients with ALD.

Differences in healthcare expenditure estimates according to statistical approach: A nationwide claims database study on patients with hepatocellular carcinoma

AIM

Disease-associated healthcare expenditures are generally calculated using matched comparisons or regression-based analyses, but little is known about their differences in estimates. This aim of this study was to compare the differences between disease-associated healthcare expenditures estimated using these 2 methods.

METHODS

In this retrospective cohort study, a matched comparison was first conducted by matching cases with controls using sex, age, and comorbidities to estimate disease-associated expenditures. The cases were then used in a fixed-effects analysis that compared expenditures before and after disease occurrence. The subjects were adults (≥20 years) with primary hepatocellular carcinoma (HCC) who underwent treatment (including surgical resection, locoregional therapy, transcatheter arterial chemoembolization, and transarterial embolization) at a Japanese hospital between April 2010 and March 2018. We calculated the total healthcare expenditures per patient per month according to treatment and disease phase (initial, continuing, and terminal).

RESULTS

There were 14,923 cases in the initial/continuing phases and 15,968 cases in the terminal phase. In the initial/continuing phases, 3,552 patients underwent surgical resection only, with HCC-associated expenditures of $5,555 according to the matched comparison and $5,889 according to the fixed-effects analysis (proportional difference: 94.3%). The initial phase expenditures were approximately 9% higher in the fixed-effects analysis, whereas the continuing phase expenditures were approximately 7% higher in the matched comparison. The expenditures in the terminal phase were 93.1% higher in the fixed-effects analysis.

CONCLUSIONS

The 2 methods produced similar estimates of HCC-associated healthcare expenditures in the initial/continuing phases. However, terminal phase expenditures were substantially different between the methods.

Alcohol Consumption Influences Clinical Outcome in Patients Admitted to a Referral Center for Liver Disease

INTRODUCTION AND AIM

Excessive alcohol consumption is a public health concern worldwide and has been associated with high mortality rates. This study aimed to determine the prevalence of alcohol consumption and its influence on the prognosis of hospitalized cirrhotic patients in a tertiary care hospital.

MATERIAL AND METHODS

We reviewed the medical records of all patients with hepatic cirrosis admitted between January 2009 and December 2014, in a referral center for liver disease in southern Brazil. Data on clinical outcomes, associated conditions, infections, and mortality were collected and compared between alcoholic and nonalcoholic patients.

RESULTS

The sample consisted of 388 patients; 259 (66.7%) were men. One hundred fifty-two (39.2%) were classified as heavy use of alcohol. Most alcoholic patients were men (n = 144; 94.7%). Mean age was 55.6 ± 8.9 years. Hepatic decompensations and infections were more prevalent in alcoholic patient. Spontaneous bacterial peritonitis and respiratory tract infection accounted for most of the infections. Excessive alcohol consumption was associated with mortality (P = 0.009) in multivariate analysis.

CONCLUSION

On the present study, the prevalence of heavy use of alcohol was high and associated with a poorer prognosis in hospitalized cirrhotic patients, increasing the risk of infection and death.

β-Thalassemia heterozygote state detrimentally affects health expectation

BACKGROUND

Thalassemia minor (Tm) individuals, are generally considered healthy. However, the prognosis of Tm individuals has not been extensively studied. The aim of this study was to evaluate the prognosis of Tm versus controls without β-thalassemia carrier state.

METHODS

A total of 26,006 individuals seeking thalassemia screening at the AOOR Villa Sofia-V. Cervello, Palermo (Italy) were retrospectively studied. Logistic penalised regression model was used to estimate risk of potential complications and survival techniques were used to study mortality.

RESULTS

We identified a total of 4943 Tm and 21,063 controls. Tm was associated with significantly higher risks of hospitalisation for cirrhosis (OR 1·94, 95% CI 1·30 to 2·90, p = 0·001), kidney disorders (OR 2·11, 95% CI 1·27 to 3·51, p = 0·004), cholelithiatis (OR 1·39, 95% CI 1·08 to 1·79, p = 0·010), and mood disorders (OR 2·08, 95% CI 1·15 to 3·75, p = 0·015). No statistically difference in life expectancy between thalassemia minor and control group was found (HR 1·090, 95% CI 0·777 to 1·555, p < 0·590; log-rank test p = .426).

CONCLUSION

This study shows that Tm affects the prognosis of Tm carriers regarding health expectation. Probably, iron overload and anaemia for several years may be at the basis of these effects.

Mortality Associated with Hepatobiliary Disease in Portugal between 2006 and 2012

INTRODUCTION

Hepatobiliary disease is becoming a major public health problem, and recent data suggest that the burden of liver disease is higher than previously thought. Our aim was to quantify the mortality from hepatobiliary disease in Portugal and to compare this with the mortality related o other causes over a 7-year period (2006-2012).

MATERIALS AND METHODS

A statistical analysis of mortality data according to cause, sex, age, and region from the National Statistics Institute in Portugal was carried out. The data related to 14 causes of death, the most frequent of which were alcoholic liver disease (ALD) (International Classification of Diseases code K70), unspecified cirrhosis of liver (UCL) (K74.6), hepatocellular carcinoma (HCC) (C22.0), unspecified malignant neoplasm of liver (C22.9), and cholangiocarcinoma (C22.1).

RESULTS

Between 2006 and 2012, 18,279 deaths (24.5/100,000) from hepatobiliary disease were registered in Portugal, constituting the 8th leading cause of death. The main causes of death from hepatobiliary disease were ALD (7.1/100,000), UCL (5.5/100,000), and HCC (4.3/100,000), with a male predominance (72%). ALD was the main aetiology in younger age groups (40-65 years), while primary neoplasms of the liver and the intrahepatic bile ducts were predominant in the elderly (>80 years). The mortality related to HCC increased by 66% between 2006 and 2012.

CONCLUSION

These data outline the burden of hepatobiliary disease in Portugal (8th cause of death) and highlight a potential impact on economic productivity.

Economic burden of cirrhosis in Catalonia: a population-based analysis

BACKGROUND

Cirrhosis is a chronic disease with high morbidity and mortality. Few studies have evaluated healthcare resource use in patients with cirrhosis.

OBJECTIVE

We aimed to describe the point prevalence of cirrhosis on 31 December 2012 and the population-level distribution of healthcare resource use and expenditures in a non-selected population of patients with cirrhosis, stratified by whether their disease was compensated or decompensated, and by comorbidity burden.

METHODS

This population study included all known patients aged >18 years with cirrhosis (according to International Classification of Diseases, ninth revision) in Catalonia, Spain, on 31 December 2012. We evaluated healthcare resource use and expenditure during 2013, taking into account the presence of decompensation before or during 2012.

RESULTS

We documented 34 740 patients diagnosed with cirrhosis (58.7% men; mean age 61.8±14 years), yielding a point prevalence of 460 per 100 000 inhabitants on 31 December 2012. Annual mortality was 9.1%. During 2013, healthcare expenditures on patients with cirrhosis totalled €142.1 million (€4234 per patient), representing 1.8% of the total 2013 healthcare budget of Catalonia. Hospitalisation costs accounted for 35.1% of the total expenditure and outpatient care accounted for 22.4%. MultivariateMultivariate logistic regression identified morbidity burden, HIV infection, hospitalisation and emergency room visits during 2012 as independent predictors of expenditure above the 85th centile (area under the receiver operating curve, 0.88 (95% CI 0.883 to 0.893, P<0.001)).

CONCLUSIONS

Cirrhosis accounts for a high proportion of healthcare resource usage and expenditures; hospitalisation accounted for the highest expenditures.

Cost of illness of non-alcoholic liver cirrhosis in Japan: A time trend analysis and future projections

AIM

Liver cirrhosis is a preneoplastic condition to hepatocellular carcinoma that is an important worldwide public health concern, and its economic burden has been estimated in some countries. The objective of this study was to estimate and predict the cost of illness (COI) associated with non-alcoholic liver cirrhosis in Japan.

METHODS

Using a COI method on available data from government statistics, we estimated the economic burden in 3-year intervals from 1996 to 2014. We then predicted the COI in 3-year intervals from 2017 to 2029 using fixed and variable model estimations. With fixed model estimation, only the estimated future population was used as a variable. Variable model estimation considered the time trends of health-related indicators throughout the past 18 years.

RESULTS

The estimated COI of non-alcoholic liver cirrhosis was ¥208.1bn in 2014. The COI of non-alcoholic liver cirrhosis had a downward trend from 1996 to 2014. The predicted future COI of non-alcoholic liver cirrhosis was ¥144.3-210.5bn, ¥106.0-213.8bn, ¥88.6-213.4bn, ¥76.7-215.5bn, and ¥66.4-214.3bn in 2017, 2020, 2023, 2026, and 2029, respectively.

CONCLUSIONS

The results of this study suggest that the COI of non-alcoholic liver cirrhosis in Japan has steadily decreased and will continue to decrease. Treatment of patients with hepatitis C virus infection with newly introduced technologies has high therapeutic effectiveness, which will affect the future prevalence of non-alcoholic liver cirrhosis. When interpreting the results of long-term estimation, it should be noted that the results of this study were based on present conditions.

Predictive formula of coma onset and prothrombin time to distinguish patients who recover from acute liver injury

BACKGROUND AND AIM

Acute liver failure (ALF) is defined as acute liver injury (ALI) associated with coagulopathy. A follow-up strategy for ALI and characterization of ALI patients with a risk of progressing to ALF have never been established. To establish predictive markers for progression from ALI to ALF, this study compared the clinical characteristics and laboratory data on the day of registration to data from a regional referral system of patients with ALI.

METHODS

This prospective, observational study enrolled 365 consecutive patients with ALI/ALF between 2007 and 2016. We evaluated 109 ALI patients, 27 of whom satisfied the ALF criteria during observation and another 82 patients who recovered without progression to ALF.

RESULTS

Four patients died; all were in the ALF group. The variables of age, incidence of autoimmune hepatitis, model of end-stage liver disease score, values for total bilirubin and prothrombin time (PT)-international ratio, and Japan Hepatic Encephalopathy Prediction Model (JHEPM) probability at registration were significantly higher in ALF patients than in ALI patients. In multivariate analysis, PT and JHEPM were identified as risk factors for progression to ALF. The cut-off values of 13%, 4.9%, 65%, and 1.32% for the model of end-stage liver disease score, JHEPM probability, PT, and PT-international ratio values, respectively, had high negative predictive values. Furthermore, among patients whose JHEPM was underestimated, none died due to ALF.

CONCLUSION

The JHEPM probability is a predictive parameter that can be used to decide a follow-up treatment strategy for ALI patients.

Hepatitis C in a Mobile Low-Threshold Methadone Program

INTRODUCTION

Data on the epidemiology of hepatitis C among individuals who use drugs in low-threshold settings are lacking, although crucial to assess the burden of disease and aid in the design of treatment strategies.

OBJECTIVE

The aim of this study was to characterize the epidemiology and disease related to hepatitis C in a population attending a low-threshold methadone program.

MATERIALS AND METHODS

A cross-sectional study in the population attending the Mobile Low-Threshold Methadone Program in Lisbon, Portugal, was carried out. The survey included assessment of risk factors for infection with hepatitis C virus (HCV) and liver disease, HCV serology and RNA detection, HCV genotyping, and liver disease staging.

RESULTS

A total of 825 participants were enrolled, 81.3% men, mean age 44.5 years. Injecting drug use (IDU) was reported by 58.4% - among these, 28.2% were people who inject drugs. Excessive drinking and HIV coinfection were reported by 33.4 and 15.9%, respectively. Among participants with active infection, 16.9% were followed up in hospital consultation. The overall seroprevalence for HCV was 67.6% (94.2% in IDU, 30.0% in non-IDU, 97.1% in people who inject drugs, and 75.6% in excessive drinkers). Among seropositives for HCV, active infection was present in 68.4%. Among individuals with active infection, the most common genotypes were 1a (45.3%) and 3a (28.7%), whereas 30% had severe liver fibrosis or cirrhosis. Age 45 years or older, HCV genotype 3, and coinfection with HIV were significant predictors of cirrhosis.

CONCLUSION

This population has a high burden of hepatitis C and several characteristics that favor dissemination of infection. Healthcare strategies are urgently needed to address hepatitis C in this setting.
