A chronic disease management model for chronic liver failure

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.

The Chronic Liver Disease Nurse Role in Australia: Describing 10 Years of a New Role in Cirrhosis Management

Cirrhosis of the liver is increasing, with growing patient numbers in hospital outpatient departments, as well as increasing admissions due to decompensated liver disease. Decompensated cirrhosis of the liver is a common and debilitating illness causing disability, readmissions to hospital, and decreased quality of life, and can lead to liver cancer. The advent of the chronic liver disease nurse (CLDN) position in our hospital in 2009 was the first role in Australia dedicated to providing care to patients with cirrhosis. The role incorporates the care of patients with stable compensated disease, case management of patients with complications of decompensated disease, and hepatocellular carcinoma coordination. After a pilot randomized controlled trial and almost 10 years of service, this article describes the role of the CLDN and presents key performance indicators that will assist other centers considering introducing the role or elements of it into their service.

Medication-Related Problems in Outpatients With Decompensated Cirrhosis: Opportunities for Harm Prevention

People with decompensated cirrhosis are often prescribed a complex regimen of therapeutic and prophylactic medications. In other chronic diseases, polypharmacy increases the risk of medication misadventure and medication-related problems (MRPs), with associated increased morbidity, mortality, and health care costs. This study examined MRPs in a cohort of ambulatory patients with a history of decompensated cirrhosis who were enrolled in a randomized controlled trial of a pharmacist-led, patient-oriented medication education intervention and assessed the association between MRPs and patient outcomes. A total of 375 MRPs were identified among 57 intervention patients (median, 6.0; interquartile range, 3.5-8.0 per patient; maximum 17). Nonadherence (31.5%) and indication issues (29.1%) were the most prevalent MRP types. The risk of potential harm associated with MRPs was low in 18.9% of instances, medium in 33.1%, and high in 48.0%, as categorized by a clinician panel using a risk matrix tool. Patients had a greater incidence rate of high-risk MRPs if they had a higher Child-Pugh score (incidence rate ratio [IRR], 1.31; 95% confidence interval [CI], 1.09-1.56); greater comorbidity burden (IRR, 1.15; 95% CI, 1.02-1.29); and were taking more medications (IRR, 1.12; 95% CI, 1.04-1.22). A total of 221 MRPs (58.9%) were resolved following pharmacist intervention. A greater proportion of high-risk MRPs were resolved compared to those of low and medium risk (68.9% versus 49.7%; P < 0.001). During the 12-month follow-up period, intervention patients had a lower incidence rate of unplanned admissions compared to usual care (IRR, 0.52; 95% CI, 0.30-0.92). Conclusion: High-risk MRPs are prevalent among adults with decompensated cirrhosis. Pharmacist intervention facilitated identification and resolution of high-risk MRPs and was associated with reduced incidence rate of unplanned hospital admissions in this group.

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

BACKGROUND AND AIMS

In this follow-up study to a randomized controlled trial of a chronic disease management (CDM) model in cirrhosis, our aim was to assess the relative cost-effectiveness of this model compared with usual care during the 12-month study period, using incremental costs per death avoided as the primary outcome.

METHODS

Mean differences in hospitalization costs, deaths avoided, and change in Chronic Liver Disease Questionnaire (CLDQ) total scores were presented with 95% non-parametric bootstrapped confidence intervals. Results were also presented using a cost-effectiveness plane (CEP) and cost-effectiveness acceptability curve.

RESULTS

The CDM intervention was more expensive, by 18 521 AUD per participant, but more effective (% of deaths at 12 months: 10% vs 15% and 0.67 units increase per patient in CLDQ total scores). The resultant incremental cost-effectiveness ratios were 370 425 AUD per death avoided (95% confidence interval: -14 564 AUD to 2 059 373 AUD) and 27 547 AUD per unit improvement in the CLDQ total score (95% CI: 7455 AUD to 143 874 AUD). The CEPs demonstrated some uncertainty around cost-effectiveness. The cost-effectiveness acceptability curves demonstrated that at willingness to pay values of 400 000 AUD per additional death avoided and 40 000 AUD per unit improvement in the CLDQ, there was at least a 70% probability of CDM being more cost-effective than usual care. At 24 months, CDM was much more effective (12% less deaths but now also cheaper by 985 AUD per patient).

CONCLUSIONS

The analysis of data from a randomized controlled trial suggests that the CDM intervention used is likely to be cost-effective, relative to usual care, due to fewer patient deaths.

Frailty as Tested by Gait Speed is an Independent Risk Factor for Cirrhosis Complications that Require Hospitalization

OBJECTIVES

Frailty is a known risk factor for major life-threatening liver transplant complications, deaths, and waitlist attrition. Whether frailty indicates risk for adverse outcomes in cirrhosis short of lethality is not well defined. We hypothesized that clinical measurements of frailty using gait speed and grip strength would indicate the risk of subsequent hospitalization for the complications of cirrhosis.

METHODS

We assessed frailty as gait speed and grip strength in a 1-year prospective study of 373 cirrhotic patients evaluated for or awaiting liver transplantation. We determined its association with the outcome of subsequent hospital days/100 days at risk for 7 major complications of cirrhosis. We tested potential covariate influences of Model for Endstage Liver Disease (MELD) and Child-Turcotte-Pugh (CTP) scores, age, sex, height, depression, narcotic use, vitamin D deficiency, and hepatocellular carcinoma using multivariable modeling.

RESULTS

Patients experienced 2.14 hospital days/100 days at risk, or 7.81 days/year. Frailty measured by gait speed was a strong risk factor for hospitalization for all cirrhosis complications. Each 0.1 m/s gait speed decrease was associated with 22% greater hospital days (P<0.001). Grip strength showed a similar but nonsignificant association. Gait speed remained independently significant when adjusted for MELD, CTP, and other covariates. At hospital costs of $4,000/day, patients with normal 1 m/s gait speed spent 6.2 days and $24,800/year; patients with 0.5 m/s speed spent 21.2 days and $84,800/year; and patients with 0.25 m/s speed spent 40.2 days and $160,800/year.

CONCLUSIONS

Frailty as measured by gait speed is an independent and potentially modifiable risk factor for cirrhosis complications requiring hospitalization. The potential clinical value of frailty measurements to help define such risk merits broader evaluation.

Population-representative Incidence of Acute-On-Chronic Liver Failure: A Prospective Cross-Sectional Study

BACKGROUND

Acute-on-chronic liver failure (ACLF) is a major cause of hepatic death in the world, but no population-based studies have evaluated the incidence of ACLF. This study was conducted to determine the incidence and short-term outcomes of ACLF in a region of Eastern China.

METHODS

In this prospective cross-sectional study, we collected data from public hospitals in Nantong city between January 1, 2005, and December 31, 2014. All hospitals with admission potential for ACLF patients were included. The primary outcome was ACLF defined as severe jaundice and coagulopathy with underlying chronic liver disease, according to diagnostic and laboratory criteria suggested by Chinese Society for Hepatology (CSH).

RESULTS

During the 10-year period, a consecutive sample of 1934 ACLF patients was included in this study. The overall ACLF incidence rate over the 10-year period was 2.53 (95% confidence interval, 2.16-2.91) per 100,000 population per year, decreasing from 3.35 in 2005 to 2.06 in 2014. Chronic hepatitis B virus (HBV) infection was the leading cause of chronic liver disease and HBV reactivation was the most common cause of acute hepatic event. The 28-day mortality for the ACLF patients had a clear decline during the study period, form 50.39% in 2005 to 35.44% in 2014.

CONCLUSIONS

In the Eastern China population, the incidence of ACLF is decreasing and the prognosis improving. Short-term mortality was associated with the presence of cirrhosis and growing age. While ACLF remains a life-threatening disorder, our findings suggest that nationwide and long-term cohorts should be conducted for the natural history of ACLF.
