Lower prevalence of elevated liver stiffness measurements in people with type 2 diabetes taking sodium-glucose co-transporter 2 inhibitors or glucagon-like peptide-1 receptor agonists.

INTRODUCTION AND OBJECTIVES: Among people with type 2 diabetes (T2D), non-alcoholic fatty liver disease (NAFLD) is very common and has an increased risk of clinically significant liver disease. The use of sodium-glucose co-transporter 2 (SGLT2i) inhibitors and glucagon-like peptide-1 (GLP-1a) receptor agonists is endorsed to reduce major cardiovascular events and/or progression of chronic kidney disease. Their prevalence of use in people with T2D and co-existent NAFLD remains unclear. We sought to determine the prevalence of use of these medications at two different time periods, and their association with prevalence of clinically significant liver disease. MATERIALS AND METHODS: Consecutive people with type 2 diabetes (T2D) and non-alcoholic fatty liver disease (NAFLD) were recruited from diabetes clinics between Jun-2021 and Jun-2022 ('current' cohort). Liver stiffness measurements (LSM) using FibroScan were performed. Medication data were collected prospectively at recruitment and verified with the dispensing pharmacy or general practitioner medical records. Data for a historical cohort with NAFLD and T2D recruited from the same clinics during 2015-2017 ('historical' cohort) were available. Logistic regression was used to evaluate factors associated with LSM <8.0 or ≥8 kPa (clinically significant fibrosis). RESULTS: There were 292 participants, 177 in the historical cohort and 115 in the current cohort. In the current cohort, 57.4% of patients with T2D and NAFLD were taking a GLP-1a and 42.6% were taking a SGLT2i; a 2.6 to 3.4-fold higher prevalence than in 2015-2017. A lower proportion of the current cohort (23.9% compared to 38.4%) had clinically significant fibrosis (LSM ≥8 kPa; p = 0.012). When the cohorts were pooled and differences adjusted for in multivariable logistic regression analysis, patients taking a GLP-1a or a SGLT2i were 2 times more likely to have a lower LSM (<8 kPa) compared to patients not taking these drugs (OR=2.05, 95%CI 1.07-3.94, p = 0.03 and OR 2.07 95%CI 1.04-4.11, p = 0.04, respectively). CONCLUSIONS: The observation of a lower LSM in people taking SGLT2i and/or GLP-1a following adjustment for other relevant clinico-demographic variables provides support for clinical trials to assess their efficacy in reducing the progression of NAFLD.

An exploration of barriers and facilitators to implementing a nonalcoholic fatty liver disease pathway for people with type 2 diabetes in primary care.

AIMS: We explored barriers and facilitators to the implementation of nonalcoholic fatty liver disease (NAFLD) pathway for people with diabetes to identify determinants of behaviour surrounding the diagnosis, assessment and management of NAFLD. METHODS: Health practitioners (n = 24) recruited from multidisciplinary diabetes clinics in primary care (n = 3) and hospital (n = 1) settings participated in four focus group discussions, and common themes were identified using thematic analysis. RESULTS: Lack of knowledge and access to resources were key factors that underpinned an inconsistent approach by clinicians to NAFLD diagnosis and risk stratification and impacted their confidence to discuss the diagnosis with patients. Participants often prioritised other medical issues above NAFLD due to lack of concern about liver-related consequences, reluctance to overburden patients with information, lack of time and perceived absence of accessible fibrosis tests. All participants agreed that implementation of a NAFLD pathway would improve patient care and the general practitioners proposed that screening for NAFLD could be incorporated into routine review cycles for type 2 diabetes. A consistent message from participants was that educating patients about their liver disease needs to be implemented in an integrated care pathway. CONCLUSIONS: From the perspectives of health practitioners, there is a gap in clinical practice for the implementation of clear, evidence-based guidelines for NAFLD in people with T2D. By focusing on comorbidity prevention and integrating NAFLD as a diabetes complication to be addressed during established cycles of care, many barriers to implementing a NAFLD pathway in primary care could be overcome.

Poor disease knowledge is associated with higher healthcare service use and costs among patients with cirrhosis: an exploratory study.

BACKGROUND: Optimal management of cirrhosis is complex, and patients often lack knowledge and skills, which can affect self-management. We assessed patient knowledge about cirrhosis and examined whether knowledge was associated with clinical outcomes, healthcare service use, and healthcare costs. A cross-sectional 'knowledge survey' was conducted during 2018-2020. We assessed patient knowledge about cirrhosis and explore whether knowledge was associated with clinical outcomes, healthcare service use, and costs. METHODS: Patients with cirrhosis (n = 123) completed a 'knowledge survey'. We calculated the proportion of correct answers to eight questions deemed to be "key knowledge" about cirrhosis by an expert panel, and dichotomized patients as 'good knowledge'/'poor knowledge'. Clinical data, healthcare costs, and health-related quality of life (SF-36) were available. RESULTS: 58.5% of patients had 'good knowledge' about cirrhosis. Higher education level was associated with higher odds of having 'good knowledge' about cirrhosis (adjusted-OR = 5.55, 95%CI 2.40-12.84). Compared to patients with 'poor knowledge', those with 'good knowledge' had a higher health status in the SF-36 physical functioning domain (p = 0.011), fewer cirrhosis-related admissions (adjusted incidence rate ratio [IRR] = 0.59, 95%CI 0.35-0.99) and emergency presentations (adj-IRR = 0.34, 95%CI 0.16-0.72), and more planned 1-day cirrhosis admissions (adj-IRR = 3.96, 95%CI 1.46-10.74). The total cost of cirrhosis admissions was lower for patients with 'good knowledge' (adj-IRR = 0.30, 95%CI 0.29-0.30). CONCLUSION: Poor disease knowledge is associated with increased use and total cost of healthcare services. Targeted educational interventions to improve patient knowledge may be an effective strategy to promote a more cost-effective use of healthcare services.

Towards collaborative management of non-alcoholic fatty liver disease: a 'real-world' pathway for fibrosis risk assessment in primary care.

BACKGROUND: The optimal strategy to support primary care practitioners (PCP) to assess fibrosis severity in non-alcoholic fatty liver disease (NAFLD) and thereby make appropriate management decisions remains unclear. AIMS: To examine the feasibility of using a two-step pathway that combined simple scores (NAFLD Fibrosis Score and Fibrosis-4 Index) with transient elastography (FibroScan) to streamline NAFLD referrals from a 'routine' primary care population to specialist hepatology management clinics (HMC). METHODS: The two-step 'Towards Collaborative Management of NAFLD' (TCM-NAFLD) fibrosis risk assessment pathway was implemented at two outer metropolitan primary healthcare practices in Brisbane. Patients aged ≥18 years with a new or established PCP-diagnosis of NAFLD were eligible for assessment. The pathway triaged patients at 'high risk' of clinically significant fibrosis to HMC for specialist review, and 'low risk' patients to receive ongoing management and longitudinal follow up in primary care. RESULTS: A total of 162 patient assessments between June 2019 and December 2020 were included. Mean age was 58.7 ± 11.7 years, 30.9% were male, 54.3% had type 2 diabetes or impaired fasting glucose, and mean body mass index was 34.2 ± 6.9 kg/m2 . A total 122 patients was considered 'low risk' for clinically significant fibrosis, two patients had incomplete assessments and 38 (23.5%) were triaged to HMC. Among 31 completed HMC assessments to date, 45.2% were considered to have clinically significant (or more advanced) fibrosis, representing 9.2% of 153 completed assessments. CONCLUSION: Implementation of the two-step TCM-NAFLD pathway streamlined hepatology referrals for NAFLD and may facilitate a more cost-effective and targeted use of specialist hepatology resources.

Implementing the right care in the right place at the right time for non-alcoholic fatty liver disease (NAFLD-RRR study): a study protocol for a community care pathway for people with type 2 diabetes.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is an emerging epidemic that affects approximately half of all people with type 2 diabetes. Those with type 2 diabetes are a high-risk NAFLD subgroup because of their increased risk of clinically significant liver-related outcomes from NAFLD which include hepatocellular carcinoma, cirrhosis-related complications and liver disease mortality. They may benefit from early detection of disease as this would allow at risk patients to access hepatocellular carcinoma surveillance, emerging drug trials for NAFLD and specialist hepatology care prior to emergence of liver-related complications. METHODS: This is a prospective cohort study aimed at incorporating and assessing a community care pathway for liver fibrosis screening into routine care for type 2 diabetes. Patients undergo a point of care assessment of hepatic steatosis and stiffness using FibroScan at the time of the routine diabetes appointment or when attending the clinic for blood tests in preparation for this appointment. DISCUSSION: We propose that implementation of a community-based NAFLD diagnosis, risk-stratification, and referral pathway for people with type 2 diabetes is feasible, will provide earlier, targeted detection of advanced fibrosis, and reduce unnecessary referrals to hepatology outpatients for fibrosis risk assessment. Our study will provide important information about the feasibility of establishing a NAFLD pathway for people with type 2 diabetes in primary care. Ultimately, our findings will help direct spending and resource allocation for NAFLD in a high-risk population. Regular evaluation by stakeholders during implementation will help to create a reliable and sustainable community care pathway and establish a perpetual cycle of learning in primary care.

Managing medicines in alcohol-associated liver disease: a practical review.

People with alcohol-associated liver disease often take medicines to manage complications of liver disease and comorbidities. However, patients may be at increased risk of drug-related harm Assessing the severity of liver disease is fundamental to management, as disease staging (steatosis, early fibrosis, cirrhosis) affects medication safety and guides treatment While clinically significant pharmacokinetic and pharmacodynamic changes predominantly occur in cirrhosis, people with early alcohol-associated liver disease may still experience adverse events with potentially inappropriate medicines such as proton pump inhibitors, opioids and benzodiazepines Regular medication review is essential to ensure ongoing appropriateness and safety Alcoholic hepatitis and cirrhosis require specialist gastroenterology or hepatology management. However, general practitioners will remain the cornerstone of day-to-day medication management.

Clinically Significant Fibrosis Is Associated With Longitudinal Increases in Fibrosis-4 and Nonalcoholic Fatty Liver Disease Fibrosis Scores.

BACKGROUND & AIMS: There is limited knowledge regarding the longitudinal utility of biomarkers of fibrosis, such as the nonalcoholic fatty liver disease (NAFLD) fibrosis score (NFS) or the fibrosis-4 score (FIB-4) score. We examined longitudinal changes in the NFS and the FIB-4 score in patients with NAFLD, with and without clinically significant fibrosis (CSF). METHODS: We performed a retrospective study of 230 patients with NAFLD, collecting clinical and laboratory records to calculate NFS and FIB-4 scores at 6 monthly intervals for 5 years before hepatology assessment of fibrosis. Linear mixed models with random intercept and slope and adjusted for age at baseline were used to assess the progression of NFS and log-transformed FIB-4 scores over time in subjects with and without CSF, determined by liver stiffness measurements of 8.2 kPa or greater. RESULTS: Patients had a median of 11 (minimum, 10; maximum, 11) retrospective observations over a median time period of 5 years (minimum, 4.5 y; maximum, 5 y). Of patients with low baseline NFS and FIB-4 scores, 31.11% and 37.76%, respectively, had CSF at the time of hepatology assessment. There was a correlation between NFS and log10 FIB-4 over time (repeated measure r = 0.55; 95% CI, 0.52-0.59). The rate of increase in NFS and log10 FIB-4 was significantly higher in patients with than without CSF (both P < .001). Predicted NFS increased by 0.17 and 0.06 units per year in subjects with and without CSF, respectively. Predicted log10 FIB-4 score increased by 0.032 and 0.0003 units per year in subjects with and without CSF, respectively. CONCLUSIONS: Noninvasively measured fibrosis scores increase progressively in patients with NAFLD and CSF. Further studies are needed to determine whether repeated measurements can identify patients at risk for CSF.

Effectiveness of patient-oriented education and medication management intervention in people with decompensated cirrhosis.

People with chronic disease often have poor comprehension of their disease and medications, which can negatively affect health outcomes. In a randomised-controlled trial, we found that patients with decompensated cirrhosis who received a pharmacist-led, patient-oriented education and medication management intervention (n = 57) had greater knowledge of cirrhosis and key self-care tasks compared with usual care (n = 59). Intervention patients also experienced improved quality of life. Dedicated resources are needed to support implementation of evidence-based measures at local centres to improve outcomes.

Underappreciation of non-alcoholic fatty liver disease by primary care clinicians: limited awareness of surrogate markers of fibrosis.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is a common cause of incidental liver test abnormalities. General practitioners (GP) have a key role in identifying people with NAFLD at risk of significant liver disease. Recent specialist guidelines emphasise the use of fibrosis algorithms or serum biomarkers rather than routine liver tests, to assess advanced fibrosis. AIM: To evaluate primary care clinicians' current approach to diagnosis, management and referral of NAFLD. METHODS: A cross-sectional survey of primary care clinicians was undertaken through a structured questionnaire about NAFLD. A convenience sample of general practice clinics and general practice conferences in Metropolitan Brisbane and regional south east Queensland was selected. RESULTS: A total of 108 primary care clinicians completed the survey (participation rate 100%). Fifty-one percent of respondents considered the prevalence of NAFLD in the general population to be ≤10%. Twenty-four percent of respondents felt that liver enzymes were sufficiently sensitive to detect underlying NAFLD. Most respondents were unsure whether the Fibrosis 4 score (62.7% unsure) or Enhanced Liver Fibrosis score (63.7% unsure) could help to identify advanced fibrosis or cirrhosis. Although 47% of respondents said they would refer a patient to a Gastroenterologist/Hepatologist if they suspect the patient has NAFLD, 44.1% do not make any referrals. Of concern, 70.6% of clinicians said they were unlikely to refer a patient to Hepatology unless liver function tests are abnormal. CONCLUSION: Our findings demonstrate that many primary care clinicians underestimate the prevalence of NAFLD and under-recognise the clinical spectrum of NAFLD and how this is assessed.

Optimising care of patients with chronic disease: patient-oriented education may improve disease knowledge and self-management.

Many patients with chronic disease do not possess the knowledge and skills required to access and interpret appropriate health information. A pilot study in people with liver cirrhosis (n = 50) identified that only 54% of patients could recall being given written information by a clinician and 64% had self-sought information, most commonly using the Internet. Many patients reported difficulties understanding the material and the majority wanted more accessible information. A pilot chronic disease educational booklet was well received by the study participants with 85% reporting it was helpful and 78% using it in between clinic appointments.

Exploratory study into the unmet supportive needs of people diagnosed with cirrhosis in Queensland, Australia.

BACKGROUND: Many patients with cirrhosis follow complex medication and dietary regimens, and those with decompensated cirrhosis suffer debilitating complications. These factors impact activities of daily living and quality of life. AIMS: To explore the concerns and challenges of people with cirrhosis and their use of support services and to also describe health professionals' (HP) perspectives of patients' concerns. METHODS: This is a cross-sectional study at a tertiary liver clinic involving 50 patients and 54 HP. Data were collected using structured questionnaires. The study includes patients' report of their challenges/problems now that they have cirrhosis ('patient-volunteered concerns') and HP' report of patients' concerns. Both also ranked a list of 10 potential concerns. RESULTS: Patients were, on average, 58 years old (SD = 10.2), mostly male (78%), Caucasian (86%) and with compensated cirrhosis (60%). The patients' most common volunteered concerns related to managing symptoms, emotional issues and disease. Most ranked 'developing liver cancer' (79%), 'losing ability to do daily tasks for yourself' (76%), 'fear of dying' (64%) and 'fear of the unknown' (64%) as priority concerns. Regarding the use of support services, 24% of patients had accessed a dietician, 20% a pharmacist and 18% a psychologist. From the HP' perspective, the patients' most significant challenges related to managing disease (65%) and symptoms (48%), access to healthcare (56%) and information/knowledge (48%). CONCLUSIONS: Our findings demonstrate that cirrhosis (its symptoms, complications and treatment) is associated with significant concerns for patients. The discrepancies between the views of HP and patients suggest that we may not be measuring or addressing patients' needs appropriately.

Can paracetamol (acetaminophen) be administered to patients with liver impairment?

Although 60 years have passed since it became widely available on the therapeutic market, paracetamol dosage in patients with liver disease remains a controversial subject. Fulminant hepatic failure has been a well documented consequence of paracetamol overdose since its introduction, while short and long term use have both been associated with elevation of liver transaminases, a surrogate marker for acute liver injury. From these reports it has been assumed that paracetamol use should be restricted or the dosage reduced in patients with chronic liver disease. We review the factors that have been purported to increase risk of hepatocellular injury from paracetamol and the pharmacokinetic alterations in different pathologies of chronic liver disease which may affect this risk. We postulate that inadvertent under-dosing may result in concentrations too low to enable efficacy. Specific research to improve the evidence base for prescribing paracetamol in patients with different aetiologies of chronic liver disease is needed.

Prevalence of medication discrepancies in patients with cirrhosis: a pilot study.

BACKGROUND: Cirrhosis patients are prescribed multiple medications for their liver disease and comorbidities. Discrepancies between medicines consumed by patients and those documented in the medical record may contribute to patient harm and impair disease management. The aim of the present study was to assess the magnitude and types of discrepancies among patient-reported and medical record-documented medications in patients with cirrhosis, and examine factors associated with such discrepancies. METHODS: Fifty patients who attended a hospital hepatology outpatient clinic were interviewed using a questionnaire composed of mixed short-response and multiple-choice questions. Patients' reported medication use was compared with documentation in the hospital medical records and pharmacy database. Medication adherence was assessed using the 8-question ©Morisky Medication Adherence Scale (MMAS-8). The multivariate logistic regression model was constructed using clinically relevant and/or statistically significant variables as determined by univariate analysis. All p-values were 2-sided (α = 0.05). RESULTS: Twenty-seven patients (54.0 %) had ≥1 discrepancy between reported and documented medicines. Patients with ≥1 discrepancy were older (p = 0.04) and multivariate analysis identified taking ≥5 conventional medicines or having a 'low' or 'medium' adherence ranking as independent predictors of discrepancy (adjusted OR 11.0 (95 % CI 1.8-67.4), 20.7 (95 % CI 1.3-337.7) and 49.0 (95 % CI 3.3-718.5) respectively). Concordance was highest for liver disease medicines (71.9 %) and lowest for complementary and alternative medicines (14.5 %) and respiratory medicines (0 %). CONCLUSION: There is significant discrepancy between sources of patient medication information within the hepatology clinic. Medication reconciliation and medicines-management intervention may address the complex relationship between medication discrepancies, number of medications and patient adherence identified in this study.

Implementing E-Cigarettes as an Alternate Smoking Cessation Tool during Pregnancy: A Process Evaluation at Two UK Sites.

Smoking during pregnancy increases the risk of adverse maternal and foetal health outcomes, with effective smoking cessation support important. E-cigarette use in the general population has increased rapidly in recent years, with their use viewed as an alternate, additional offer to nicotine-replacement therapy and behavioural support. However, their use in pregnancy has limited investigation. This study aimed to understand how two e-cigarette pilots for pregnant women were delivered and implemented. Referrals to the general stop smoking in pregnancy service, as well as pilot enrolment, engagement and outcomes were recorded. Seven professionals involved in pilot 2 design, setup and/or delivery took part in semi-structured interviews informed by the Consolidated Framework for Implementation Research (CFIR). Transcripts were deductively coded into CFIR. In total, 124 of 296 women accessed at least one visit after being contacted and offered the e-cigarette pilot (Pilot 1: N = 99, Pilot 2: N = 25). In Pilot 2, 13 (of 25) reached 4 weeks, and common reasons for withdrawal by 12 weeks included relapse, loss of contact and no further support wanted. Forty-five (36.3%) validated quits were reported (Pilot 1: 32 of 99 (32.3%); Pilot 2: 13 of 25 (52%)). Facilitators included regular communication and the advisors physically taking e-cigarettes to home visits. Barriers included misalignment between the pilot and the standard treatment offer and availability of the staff resource. Enrolment to both pilots was demonstrated, with greater enrolment in one pilot and notable quit rates among women across both pilots. The perceived role of e-cigarettes for pregnant women varied, and a lack of staff resources explained some challenges. Adaptations may be needed during scale-up, including additional resources and the alignment of the e-cigarette provision to standard treatment.

Provision of E-Cigarettes for Smoking Cessation in Pregnancy: Perceptions and Experiences of Pregnant Women from Two UK Sites.

INTRODUCTION: Smoking in pregnancy is associated with negative health outcomes for both mothers and babies; e-cigarettes, which contain nicotine without hazardous tobacco, may offer an additional smoking cessation strategy for pregnant women. Although e-cigarettes are being increasingly offered within services, there is limited understanding about whether e-cigarettes can improve smoking cessation support for pregnant individuals. This study aimed to explore service users' experiences of using e-cigarettes as a tool for smoking cessation during pregnancy. METHODS: Semi-structured interviews were conducted with 14 women who had accepted one of two pilots and were analysed using inductive reflexive thematic analysis. The findings from each site were integrated to develop qualitative insight. RESULTS: Participants largely had positive perceptions of the free and easy-to-use e-cigarette, preferring it to nicotine replacement therapies. The desire to have a healthy pregnancy and baby and the inclusion of non-judgemental behavioural support facilitated motivation to quit. Many participants reduced or quit tobacco use, with positive social and health implications reported. However, numerous barriers to quitting were present and intentions about long-term quitting of combustible cigarettes and e-cigarettes were mixed and uncertain. CONCLUSIONS: Providing e-cigarettes within smoking cessation services was indicated to be a positive and effective strategy for pregnant women trying to quit tobacco. However, numerous barriers to quitting and staying quit remained, suggesting scope for further improvements to smoking cessation support for pregnant women.

Changing Prevalence of Medication Use in People with Cirrhosis: A Retrospective Cohort Study Using Pharmaceutical Benefits Scheme Data.

BACKGROUND: Safe and appropriate use of medicines is essential to improve health outcomes in cirrhosis. However, little is known about the number and type of medicines dispensed to people with cirrhosis in Australia, as this predominantly occurs in the community. We aimed to characterise the prescriptions dispensed to people with cirrhosis and explore changes in the use of medication groups over time. METHODS: Pharmaceutical Benefits Scheme data between 1 January 2016 and 30 June 2020 was extracted for consenting CirCare participants (multi-site, prospective, observational study). Prescriptions dispensed from cirrhosis diagnosis until liver transplant or death were included. Safety classifications for dispensed medicines were defined using published evidence-based recommendations. The pattern of medication use was analysed in 6-monthly time intervals. Generalised estimating equations models were used to estimate the change in consumption of medicines over time. RESULTS: Five hundred twenty-two patients (mean age 60 years, 70% male, 34% decompensated at recruitment) were dispensed 89,615 prescriptions during the follow-up period, representing a median of 136 [interquartile range (IQR) 62-237] prescriptions and a median of 16 (IQR 11-23) unique medicines per patient (total n = 9306 medicines). The most commonly used medicines were proton pump inhibitors (PPIs) (dispensed at least once to 73% of patients), opioids (68%) and antibiotics (89%). Polypharmacy was prevalent, with 59-69% of observed participants in each time period dispensed five or more unique medicines. Prescription medication use increased over time (p < 0.001) independently of age, comorbidity burden and liver disease aetiology. The likelihood of taking PPIs, opioids, antidepressants and inhaled medicines also increased with each successive time period. Use of angiotensin therapies, metformin and statins differed over time between patients with compensated versus decompensated cirrhosis. General practitioners prescribed 69% of dispensed medicines, including a higher proportion of 'unsafe' and 'safety unknown' medicines compared with consultants/specialists (p < 0.001). CONCLUSIONS: Polypharmacy is common in people with cirrhosis and some medication groups may be overused. Pharmacovigilance is required and future medication safety efforts should target high-risk prescribing practices and promote medication rationalisation in the community.

Predicting Liver-Related Outcomes in People With Nonalcoholic Fatty Liver Disease: The Prognostic Value of Noninvasive Fibrosis Tests.

It remains unclear whether screening for advanced fibrosis in the community can identify the subgroup of people with nonalcoholic fatty liver disease (NAFLD) at higher risk for development of liver-related complications. We aimed to determine the prognostic value of baseline noninvasive fibrosis tests for predicting liver-related outcomes and mortality in patients with NAFLD from type 2 diabetes (T2D) clinics or primary care. Patients (n = 243) who were screened for NAFLD with advanced fibrosis by using NAFLD fibrosis score (NFS), fibrosis 4 score (FIB-4), enhanced liver fibrosis (ELF) test, and liver stiffness measurements (LSMs) were followed up for clinical outcomes by review of electronic medical records. During a median follow-up of 50 months, decompensated liver disease or primary liver cancer occurred in 6 of 35 (17.1%) patients with baseline LSM > 13 kPa, 1 of 17 (5.9%) patients with LSM 9.5-13 kPa, and in no patients with LSM < 9.5 kPa. No patient with low-risk NFS developed liver decompensation or liver-related mortality. Following repeat NFSs at the end of follow-up, all patients with a liver-related complication were in the high-risk NFS category. Patients who developed liver-related complications were also more likely to have baseline high-risk FIB-4 scores or ELF test ≥9.8 compared to patients who did not develop liver outcomes. Conclusion: Liver fibrosis risk stratification in non-hepatology settings can identify the subset of patients at risk of liver-related complications. Although the rate of development of a decompensation event or hepatocellular carcinoma was low (2.1% per year) in our patients with compensated cirrhosis (LSM > 13 kPa), these events are projected to lead to a substantial increase in NAFLD-related disease burden over the next decade due to the high prevalence of NAFLD in people with obesity and T2D.

Detecting non-alcoholic fatty liver disease and risk factors in health databases: accuracy and limitations of the ICD-10-AM.

OBJECTIVE: The prevalence of non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) cirrhosis is often underestimated in healthcare and administrative databases that define disease burden using International Classification of Diseases (ICD) codes. This retrospective audit was conducted to explore the accuracy and limitations of the ICD, Tenth Revision, Australian Modification (ICD-10-AM) to detect NAFLD, metabolic risk factors (obesity and diabetes) and other aetiologies of chronic liver disease. DESIGN/METHOD: ICD-10-AM codes in 308 admitted patient encounters at two major Australian tertiary hospitals were compared with data abstracted from patients' electronic medical records. Accuracy of individual codes and grouped combinations was determined by calculating sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and Cohen's kappa coefficient (κ). RESULTS: The presence of an ICD-10-AM code accurately predicted the presence of NAFLD/NASH (PPV 91.2%) and obesity (PPV 91.6%) in most instances. However, codes underestimated the prevalence of NAFLD/NASH and obesity by 42.9% and 45.3%, respectively. Overall concordance between clinical documentation and 'grouped alcohol' codes (κ 0.75) and hepatitis C codes (κ 0.88) was high. Hepatitis B codes detected false-positive cases in patients with previous exposure (PPV 55.6%). Accuracy of codes to detect diabetes was excellent (sensitivity 95.8%; specificity 97.6%; PPV 94.9%; NPV 98.1%) with almost perfect concordance between codes and documentation in medical records (κ 0.93). CONCLUSION: Recognition of the utility and limitations of ICD-10-AM codes to study the burden of NAFLD/NASH cirrhosis is imperative to inform public health strategies and appropriate investment of resources to manage this burgeoning chronic disease.
