Cost-effectiveness of a chronic disease management model for cirrhosis: Analysis of a randomized controlled trial

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.

A home-based, multidisciplinary liver optimisation programme for the first 28 days after an admission for acute-on-chronic liver failure (LivR well): a study protocol for a randomised controlled trial

Background

Acute-on-chronic liver failure (ACLF) represents a rising global healthcare burden, characterised by increasing prevalence among patients with decompensated cirrhosis who have a 28-day transplantation-free mortality of 33.9%. Due to disease complexity and a high prevalence of socio-economic disadvantage, there are deficits in quality of care and adherence to guideline-based treatment in this cohort. Compared to other chronic conditions such as heart failure, those with liver disease have reduced access to integrated ambulatory care services. The LivR Well programme is a multidisciplinary intervention aimed at improving 28-day mortality and reducing 30-day readmission through a home-based, liver optimisation programme implemented in the first 28 days after an admission with either ACLF or hepatic decompensation. Outcomes from our feasibility study suggest that the intervention is safe and acceptable to patients and carers.

Methods

We will recruit adult patients with chronic liver disease from the emergency departments, in-patient admissions, and an ambulatory liver clinic of a multi-site quaternary health service in Melbourne, Australia. A total of 120 patients meeting EF-Clif criteria will be recruited to the ACLF arm, and 320 patients to the hepatic decompensation arm. Participants in each cohort will be randomised to the intervention arm, a 28-day multidisciplinary programme or to standard ambulatory care in a 1:1 ratio. The intervention arm includes access to nursing, pharmacy, physiotherapy, dietetics, social work, and neuropsychiatry clinicians. For the ACLF cohort, the primary outcome is 28-day mortality. For the hepatic decompensation cohort, the primary outcome is 30-day re-admission. Secondary outcomes assess changes in liver disease severity and quality of life. An interim analysis will be performed at 50% recruitment to consider early cessation of the trial if the intervention is superior to the control, as suggested in our feasibility study. A cost-effectiveness analysis will be performed. Patients will be followed up for 12 weeks from randomisation. Three exploratory subgroup analyses will be conducted by (a) source of referral, (b) unplanned hospitalisation, and (c) concurrent COVID-19. The trial has been registered with the Australian New Zealand Clinical Trials Registry.

Discussion

This study implements a multidisciplinary intervention for ACLF patients with proven benefits in other chronic diseases with the addition of novel digital health tools to enable remote patient monitoring during the COVID-19 pandemic. Our feasibility study demonstrates safety and acceptability and suggests clinical improvement in a small sample size. An RCT is required to generate robust outcomes in this frail, high healthcare resource utilisation cohort with high readmission and mortality risk. Interventions such as LivR Well are urgently required but also need to be evaluated to ensure feasibility, replicability, and scalability across different healthcare systems. The implications of this trial include the generalisability of the programme for implementation across regional and urban centres.

Differences in the pattern and cost of hospital care between Indigenous and non-Indigenous Australians with cirrhosis: an exploratory study

BACKGROUND

Liver diseases are important contributors to the mortality gap between Indigenous and non-Indigenous Australians.

AIMS

This cohort study examined factors associated with hospital admissions and healthcare outcomes among Indigenous Australians with cirrhosis.

METHODS

Patient-reported outcomes were obtained by face-to-face interview (Chronic Liver Disease Questionnaire and Short Form 36 (SF-36)). Clinical data were extracted from medical records and through data linkage for 534 patients (25 indigenous). Cumulative overall survival (Kaplan-Meier), rates of hospital admissions and emergency presentations, and costs were assessed by indigenous status. Incidence rate ratios (IRR; Poisson regression) were reported.

RESULTS

Indigenous Australians admitted to hospital with cirrhosis had lower educational status compared with non-indigenous patients (79.2% vs 43.4%; P < 0.001). The two groups had, in general, similar clinical characteristics including disease severity (P = 0.78), presence of cirrhosis complications (P = 0.67), comorbidities (P = 0.62), rates of cirrhosis-related admissions (P = 0.86) and 5-year survival (P = 0.30). However, indigenous patients had a lower score in the SF-36 domain related to bodily pain (P = 0.037), more cirrhosis admissions via the emergency department (IRR = 1.42, 95% confidence interval (CI) 1.10-1.83) and fewer planned cirrhosis admissions (IRR = 0.32, 95% CI 0.14-0.72). The total cost for cirrhosis-related hospital admissions for 534 patients over 6 years (July 2012 to June 2018) was A$13.7 million. The cost of cirrhosis-related hospital admissions was double for indigenous patients (cost ratio = 2.04, 95% CI 2.04-2.05).

CONCLUSIONS

Our data highlight the disparities in health service use and patient-reported outcomes, despite having similar clinical profiles. Integration between primary care, Aboriginal Community Controlled Health Organisations and liver specialists is critical for appropriate health service delivery and effective use of resources. Chronic liver disease costs the community dearly.

Rising Healthcare Costs and Utilization among Young Adults with Cirrhosis in Ontario: A Population-Based Study

OBJECTIVES

Chronic diseases account for the majority of healthcare spending. Cirrhosis is a chronic disease whose burden is rising, especially in young adults. This study aimed at describing the direct healthcare costs and utilization in young adults with cirrhosis compared to other chronic diseases common to this age group.

METHODS

Retrospective population-based study of routinely collected healthcare data from Ontario for the fiscal years 2007-2016 and housed at ICES. Young adults (aged 18-40 years) with cirrhosis, inflammatory bowel disease (IBD), and asthma were identified based on validated case definitions. Total and annual direct healthcare costs and utilization were calculated per individual across multiple healthcare settings and compared based on the type of chronic disease. For cirrhosis, the results were further stratified by etiology and decompensation status.

RESULTS

Total direct healthcare spending from 2007 to 2016 increased by 84% for cirrhosis, 50% for IBD, and 41% for asthma. On a per-patient basis, annual costs were the highest for cirrhosis ($6,581/year) compared to IBD ($5,260/year), and asthma ($2,934/year) driven by acute care in cirrhosis and asthma, and drug costs in IBD. Annual costs were four-fold higher in patients with decompensated versus compensated cirrhosis ($20,651/year vs. $5,280/year). Patients with cirrhosis had greater use of both ICU and mental health services.

CONCLUSION

Healthcare costs in young adults with cirrhosis are rising and driven by the use of acute care. Strategies to prevent the development of cirrhosis and to coordinate healthcare in this population through the development of chronic disease prevention and management strategies are urgently needed.

Colonic vitamin D receptor expression is inversely associated with disease activity and jumonji domain-containing 3 in active ulcerative colitis

BACKGROUND

The expression of jumonji domain-containing 3 (Jmjd3) and trimethylated H3 lysine 27 (H3K27me3) in active ulcerative colitis (UC) and the correlation between vitamin D receptor (VDR) and the Jmjd3 pathway are unknown.

AIM

To study the relationship between VDR, Jmjd3 and H3K27me3 in patients with active UC.

METHODS

One hundred patients with active UC and 56 healthy controls were enrolled in this study. The patients with active UC were divided into groups according to mild (n = 29), moderate (n = 32) and severe (n = 29) disease activity based on the modified Mayo score. Vitamin D levels were measured by radioimmunoassay. Colonic mucosal tissues from UC patients and controls were collected by colonoscopy. The expression of VDR, Jmjd3 and H3K27me3 in the intestinal mucosa was determined by immunohistochemistry staining.

RESULTS

Patients with active UC had lower levels of serum vitamin D (13.7 ± 2.8 ng/mL, P < 0.001) than the controls (16.2 ± 2.5 ng/mL). In the UC cohort, serum vitamin D level was negatively correlated with disease activity (r = -0.323, P = 0.001). VDR expression in the mucosa of UC patients was reduced compared to that in normal tissues (P < 0.001) and negatively correlated with disease activity (r = -0.868, P < 0.001). Similar results for VDR expression were noted in the most serious lesion (defined as UC diseased) and 20 cm proximal to the anus (defined as UC normal) (P < 0.05). Simultaneously, Jmjd3 expression significantly increased in UC patients (P < 0.001), but no difference was found between the different sites in UC patients. H3K27me3 expression in UC patients was significantly down-regulated when compared with normal tissues (P < 0.001), but up-regulated in the mild disease activity group in comparison with the moderate disease activity group of UC patients (P < 0.05). Jmjd3 Level was negatively correlated with the level of VDR (r = -0.342, P = 0.002) and H3K27me3 (r = -0.341, P = 0.002), while VDR level was positively correlated with H3K27me3 (r = 0.473, P < 0.001).

CONCLUSION

Serum vitamin D and VDR were inversely correlated with disease activity in active UC. Jmjd3 expression increased in the colonic mucosa of active UC patients and was negatively associated with VDR and H3K27me3 level.

Enhancing the hepatitis B care cascade in Australia: A cost-effectiveness model

If Australia is to successfully eliminate hepatitis B as a public health threat, it will need to enhance the chronic hepatitis B (CHB) care cascade. This study used a Markov model to assess the impact, cost and cost-effectiveness of scaling up CHB diagnosis, linkage to care and treatment to reach national and international elimination targets for hepatitis B in Australia. Compared to continued current trends, the model calculated the difference in care cascade projection, disability-adjusted life years (DALYs), costs and the incremental cost-effectiveness ratio (ICER), of scaling up CHB diagnosis, linkage to care and treatment to reach: (a) Australia's 2022 national targets and (b) the WHO's 2030 global targets. Achieving the national and WHO targets had ICERs of A$13 435 (A$10 236-A$21 165) and A$14 482 (A$13 031-A$25 641) per DALY averted between 2016 and 2030 in Australia, respectively. However, this excluded implementation and demand generation costs. The ICER for the National Strategy and WHO Strategy remained under A$50 000 per DALY averted if Australia spent up to A$328 or A$538 million, respectively, per annum (for 2016-2030) on implementation and demand generation activities. Sensitivity analysis showed that cost-effectiveness was predominately driven by the cost of CHB treatment and influenced by disease progression rates. Hence for Australia to reach the National Hepatitis B Strategy 2022 targets and WHO Strategy 2030 targets, it requires an improvement in the CHB care cascade. We estimated it is cost-effective to spend up to A$328 million or A$538 million per year to reach the National and WHO Strategy targets, respectively.
