The most effective strategies to reduce the burden of cirrhosis are those which address the underlying aetiology of cirrhosis. In this section, as summarised in Figure 1, we review the evidence for multiple chronic liver diseases.
Aetiology directed therapies to prevent decompensations of cirrhosis. Patients with cirrhosis may have multiple disease aetiologies. Efforts to address alcohol use, lifestyle change and elimination or control of viral hepatitis are essential
Eradication of hepatitis C virus (HCV) is associated with a reduced risk of incident cirrhosis and its complications. Even for patients with decompensated cirrhosis, HCV eradication is associated with marked improvement in liver function. HCV eradication may lead to clinical recompensation with the resolution of HE.[6–9] Combining the trials of the direct-acting antivirals indicated for patients with decompensated cirrhosis—ledipasvir/sofosbuvir and velpatisvir/sofosbuvir—many patients returned to Child A, particularly those with single decompensations. In general, antiviral therapy is indicated for all patients with HCV. However, treatment may be best deferred to after liver transplantation for waitlisted patients with model for end-stage liver disease (MELD) scores >27 to avoid the risk of reduced MELD with persistent decompensation (MELD purgatory).[11,12] HCV eradication also reduces the risk of HCC,[13,14] but the risk of HCC can remain elevated, particularly among older persons with low platelets or albumin, high liver stiffness or fibrosis-4 indices, and those who are actively drinking alcohol.[13,15]
Similarly, control of hepatitis B is associated with substantial benefits. It is likely that antiviral therapy for hepatitis B prevents the development of cirrhosis. Antiviral therapy is also indicated for patients with chronic hepatitis B and cirrhosis. Therapy is associated with improved Child–Pugh scores and reduced risk of HCC. There is a small 5%–9% risk of increased serum creatinine >0.5 mg/dl, one which is potentially limited by the use of Tenofovir alafenamide, and, rarely, lactic acidosis. The patients at lowest risk of complications including HCC appear to be those who achieve a functional cure or loss of surface antigen >1 year. There are numerous therapies under investigation which aim to improve the rate of functional cure or complete cure (elimination of cccDNA or DNA integration). These include immunomodulators, viral entry inhibitors, core protein modulators, nucleic acid polymers, anti-sense oligonucleotides, CRISPR-Cas9, nucleases and interfering RNA.
Alcohol-related Liver Disease
The most effective therapy for alcohol-related liver disease (ALD) is abstinence and harm reduction. Psychotherapy is widely recommended and most effective when integrated with medical care. When successfully linked to care, residential or outpatient psychotherapy and counselling are associated with a reduced risk of hospital readmission. There are several pharmacotherapeutic options that are associated with reduced alcohol consumption and abstinence. Though none are specifically approved in the setting of cirrhosis, their use is associated with a reduced risk of decompensation and death. Baclofen is notable for having been studied among patients with decompensated cirrhosis and successfully reducing alcohol consumption in a small study where patients were hospitalised for the initiation of therapy. Most evidence, therefore, needs to be cautiously applied from data involving patients with alcohol use disorder without decompensated cirrhosis. The most effective therapies in alcohol use disorder are naltrexone (daily/oral or intramuscular/long-acting)[28,29] and gabapentin.[30,31] Naltrexone has a label warning is associated with transiently elevated liver enzymes based on experience in a trial of 26 obese patients; however, no liver injury has been observed in trials enrolling patients with alcohol use disorder or cholestatic liver disease (where it has been used for pruritis).[32,33] Gabapentin is unique as an agent that is effective for persons with or at risk for alcohol withdrawal symptoms.[30,34]
Non-alcoholic Steatohepatitis Cirrhosis
Weight Loss in Obese/Overweight. Weight loss through dietary and lifestyle modification is the current cornerstone of treatment for patients with non-alcoholic steatohepatitis (NASH) among overweight and obese patients (not specific to cirrhosis).[35–37] A prospective study of 261 patients with biopsy-proven NASH were encouraged to adopt recommended lifestyle changes, followed by a repeat liver biopsy. The degree of NASH and fibrosis resolution correlated with the degree of weight loss, with the greatest improvements among patients who lost ≥10% of their body weight. However, patients with cirrhosis were excluded from this study, and it is unclear if the findings of this study can be generalised to patients with cirrhosis.
Bariatric surgery appears to be effective in improving NASH among patients with severe obesity especially those with significant comorbidities. A prospective French study conducted among 180 severely obese patients with biopsy-proven NASH who underwent bariatric surgery revealed that 84% of patients had resolution of NASH 5 years after surgery. A retrospective U.S. study of 1158 patients with biopsy-proven NASH compared 650 patients who underwent bariatric surgery with 508 patients who were managed non-surgically and determined that bariatric surgery was associated with a lower risk of major adverse liver outcomes defined by diagnostic codes (adjusted absolute risk difference 12.4%). Owing to the exclusion of large numbers of patients with cirrhosis, data are insufficient for bariatric surgery to be routinely recommended for patients with NASH cirrhosis and obesity. Additional data to define the population most likely to benefit are urgently needed.
Pharmacological Therapies. To date, there are no approved pharmacological therapies for NASH, with regulatory approval hindered by challenges with clinical trials including slow disease progression, the requirement for repeat liver biopsies, and heterogenous patient populations. Several clinical trials studying candidates specifically for the treatment of NASH cirrhosis are summarised in Table 1. A recent phase 3 placebo-controlled trial of selonsertib, a selective inhibitor of apoptosis signal-regulating kinase 1 (ASK1) and a phase 2b placebo-controlled trial of simtuzumab, a humanised monoclonal antibody directed against lysyl oxidase-like 2 (LOXL2) were conducted in patients with compensated NASH cirrhosis.[41,42] Both studies were halted at week 48 and week 96 respectively due to lack of efficacy. A randomised phase 2b trial of belapectin, an inhibitor of galectin 3, among patients with NASH cirrhosis failed to reduce portal pressure. However, in a subgroup analysis of patients without varices, belapectin reduced hepatic venous pressure gradient and improved fibrosis. Therefore, another phase 2b/3 trial of belapectin specifically in patients with NASH cirrhosis and signs of portal hypertension but without baseline varices is ongoing (NCT04365868, Table 1). A placebo-controlled trial of Emricasan, a pan-caspase inhibitor, among 217 participants with decompensated NASH cirrhosis did not meet the primary endpoints (mortality, new decompensation event or rise in MELD-NA score ≥ 4 points). FALCON 2, a phase 2, randomised study of pegbelfermin, a PEGylated fibroblast growth factor 2 analogue, reported that the study failed to meet the primary endpoint of fibrosis improvement without worsening of NASH. A phase 2b trial of combination therapies (selonsertib, cilofexor or firsocostat) among 392 participants with NASH (56% with cirrhosis) demonstrated that participants treated with cilofexor/firsocostat had improvements in NASH activity, although the primary endpoint (fibrosis improvement without worsening of NASH) of the study was not met. Phase 2 trials of the glucagon-like peptide 1 (GLP-1) receptor agonists liraglutide and semaglutide (which did not include patients with cirrhosis) showed a higher resolution of NASH compared with placebo.[47,48] The PIVENs clinical trial demonstrated that Vitamin E improves liver histology in non-diabetic patients with biopsy-proven NASH. However, patients with cirrhosis were excluded from the PIVENs study.[35,49] Additional ongoing trials are summarised in Table 1.
Complications of Cirrhosis
Therapeutics for the treatment and prevention of the complications of cirrhosis are summarised in Figure 2.

Variceal Haemorrhage. Based on guidance from Baveno VI to VII, patients with compensated cirrhosis may avoid a screening oesophagogastroduodenoscopy (EGD) if their liver stiffness on vibration controlled transient elastography is <20 kPa and the platelet count is >150,000. However, recent data has emerged refining the thresholds for patients with NASH cirrhosis, with a platelet count >110,000/mm3 and LSM < 30 kPa for M probe, and platelet count >110,000/mm3 and LSM < 25 kPa for XL probe as the updated threshold beyond which a screening EGD may be avoided.
Hepatic Encephalopathy. Current best-practice for the management of HE includes nutritional support as well as therapeutic agents that mitigate the effects of factors in the causal pathway for the disease process. Given that muscle is critical for the metabolism of systemic ammonia, all patients with HE are recommended to consume 1 g dietary protein per kilogram actual bodyweight. As patients with cirrhosis often have inadequate hepatic gluconeogenesis, fasting should be avoided and all patients should consume high-calorie/high-protein night-time or early-morning snack. Branch-chain amino acids are specifically required and are frequently supplemented but may not be required in the setting of adequate protein supplementation.
Lactulose titrated to produce soft stools—specifically 2–3 bowel movements with Bristol stool scale—remains first-line and is the only agent shown to improve quality of life and sleep quality among persons with covert HE. Rifaximin has been approved for breakthrough episodes of HE on lactulose and its use is associated with reduced mortality and hospitalisations after incident HE.[57,58] Ammonia scavengers have had mixed results. Glycerol phenylbutyrate improves freedom from recurrent HE but is not available for this indication. Oral L-ornthine/L-aspartate (LOLA) is associated with improved cognitive function in small trials which do not compare to other therapies. Intravenous LOLA was recently associated with hastened recovery from overt HE compared to lactulose and rifaximin. While LOLA did not improve length of stay, it was associated with a reduction in 28-day mortality from 42% to 16%, which raises important questions about the population studied. Finally, the ammonia and glutamine scavenger, intravenous ornithine phenylacetate did not improve the resolution of overt HE compared to lactulose. Adjunctive therapies such as faecal microbiota transplantation and golexanolone (a neurosteroid antagonist) have been evaluated but not in phase 3 trials.[63,64] Case series have suggested a potential role for the closure of spontaneous portosystemic shunts, however, recurrence rates remain high.
Ascites. Ascites is a relatively neglected area of investigation. The standard of care for ascites management includes sodium restriction and combination loop and aldosterone antagonist diuretics. Sodium restriction can be efficacious but is only effective in 14% of patients. Adherence is limited and is often associated with unintended protein/calorie restriction.[66,67] This is likely due to gaps in patient education. Tapper et al. recently conducted a pilot 40-subject randomised trial of home-delivered medically-tailored sodium-restricted meals and observed lower paracentesis requirement as well as quality of life. Diuretics are often dosed in a 2:5 ratio starting with 40 mg of furosemide and 100 mg of spironolactone, escalating to a maximum of 400 mg spironolactone. Weight loss is gradual as ascites clearance occurs at a maximum of 1 L/day. Gynecomastia may worsen on spironolactone for which a switch to eplerenone (50 mg roughly equivalent to 100 mg spironolactone) or amiloride (10 mg/100 mg spironolactone) could be considered.
Hyponatremia and renal injury frequently limit the effectiveness of diuretics owing to the exacerbation of vascular underfilling and maladaptive neurohormonal activation. Advanced therapies like transjugular portosystemic intrahepatic shunts are reserved for persons with preserved liver and cardiac function. There are emerging reports regarding the role of Sodium-Glucose Cotransporter 2 (SGLT-2) inhibitors wherein patients with diabetes and refractory ascites can experience improvements in volume status with add-on SGLT-2 inhibitors. Controlled trials are needed.
Transjugular intrahepatic portosystemic shunts (TIPS) is a vital salvage therapy for ascites for appropriate candidates. In appropriate candidates, typically Child score <12 and bilirubin<5.8 g/dl with preserved cardiac function, TIPS increases the odds of freedom from paracentesis and even survival. The risk of HE is increased after TIPS but is not a contraindication. It is crucial to not stop HE therapy (ie, lactulose) if the patient is taking prior to TIPS. Beyond that, both under-dilation the TIPS (6 mm vs 8 mm) and rifaximin prior to TIPS may improve the risk of HE.[73,74]
Spontaneous bacterial peritonitis (SBP) is a frequent and morbid complication of ascites. Efforts to prevent SBP centre on identifying candidates for antibiotic prophylaxis. There are several unresolved issues. First, effectiveness is questionable. Trials in this space have had mixed results.[75,76] There are observational data suggesting that rifaximin may reduce the incidence of SBP, but these have not been confirmed in randomised trial. Data from a large randomised trial (ASEPTIC) enrolling British patients in a trial of trimethroprim-sulfamethoxazole or placebo is forthcoming. Second, there is increasing concern that long-term antibiotics may drive resistance. Third, it is unclear if the dominant method for patient selection (ascitic protein <1.5 g/dL) actually discriminates risk. Finally, one unblinded controlled study evaluated the impact of enoxaparin on the risk of portal vein thrombosis in persons with ascites. Anticoagulation was associated with decreased thrombosis and also SBP, likely by decreasing bacterial translocation.
Hepatorenal syndrome (HRS) is the most devastating complication of ascites. The standard of care varies with access to approved therapies. As HRS is defined by a lack of fluid responsiveness, first-line therapy is an albumin infusion. However, the optimal dose and duration of albumin infusion are unknown. In a recent trial (CONFIRM), there was clear evidence of harm (respiratory failure) attributed to high cumulative doses of albumin in the context of increased afterload caused by vasoconstrictor therapy. Elsewhere, it has been observed in trials of ultrasound-guided estimations of intravascular volume that many patients meet criteria for HRS without volume depletion and, in fact, benefit from early vasoconstrictors or paracentesis (to addresses abdominal compartment pressures). The preferred vasoconstrictor therapy in Europe is terlipressin[83,84] while octreotide and midodrine are typically used where terlipressin is unavailable. Terlipressin is superior compared to octreotide/midodrine and yields similar results in comparison to norepinephrine. Unfortunately, although terlipressin often reverses HRS, it has not been associated with a survival benefit. In fact, the outcomes after HRS have not changed over multiple decades.
Sarcopenia and Frailty. Sarcopenia, loss of muscle bulk and frailty, diminished physiologic reserve, are well-established sequelae of cirrhosis.[53,86] These conditions result from malnutrition, hyperammonemia, negative energy balance (particularly due to ascites or fasting), and are potent predictors of falls, HE and mortality.[87–89] The nutritional management of sarcopenia and frailty are summarised above and in recent AASLD guidance, focusing on late-night snacks, avoiding fasting, high (1 g/kg/day) protein and calorie (~30 kcal/kg/day) consumption, and increasing physical activity. Pharmacologic agents are limited. Patients with frailty owing to cognitive impairment may benefit from initiation or intensification of HE therapy. Beyond that, testosterone has been trialled and is a promising therapy for men with low testosterone without HCC or prostate cancer who have been counselled regarding cardiovascular risks. A trial of an oral testosterone ester is planned to address sarcopenia in patients with cirrhosis (NCT04874350). Finally, the EMPOWER trial (NCT04816916) is investigating a proprietary nutritional therapy consisting of 8 amino acids for the improvement of HE (and frailty).
Given dismal outcomes following the decompensation of cirrhosis, there is intense interest in developing therapies to forestall the progression of disease (Table 2). Few of such approaches have been examined in randomised trials with the exception of statins and non-selective beta-blockers (NSBB). NSBB reduce portal pressure, reducing the risk of variceal haemorrhage. The PREDESCI trial tested whether this reduction could translate to reduced risk of all-cause decompensation, randomising 201 compensated patients with manometry-confirmed portal hypertension to placebo or non-selective beta-blocker (propranolol or carvedilol). NSBB was associated with a reduced risk of the primary outcome, hazard ratio (HR) 0.51, 95% CI 0.26–0.97, driven by a reduced incidence of ascites, HR 0.44, 95% CI 0.20–0.97. As carvedilol is associated with a higher rate of portal pressure reduction and can be dosed daily, it may be the preferred NSBB. PREDESCI enrolled patients after portal manometry with predominantly undertreated HCV and as such further study is needed to determine whether similar effects can be observed in patients with NASH, ALD and those with elastography-based risk-assessments. Observational data regarding the impact of NSBB are less clear. A recent observational study at risk for survivorship bias suggests improved survival for patients with varices taking carvedilol compared to band-ligation (from 7.8 to 4.2 years). Another recent study of administrative data at risk for immortal time bias and confounding by indication showed a dramatic reduction in the risk of HCC with NSBB.
Statins are the subject of multiple trials. Two small randomised studies have shown short-term simvastatin reduces portal pressure.[95,96] An RCT of 158 patients found that simvastatin did not prevent variceal haemorrhage but did improve the underpowered outcome of overall survival. Observational data regarding the impact of statins suggests users are at lower risk of decompensation including bleeding, ascites and HE.[98,99] These studies are at risk of multiple biases. Similarly, a study of statins purported an implausible 50% reduction in the absolute risk of HCC. Four trials of statins are underway. First, LIVERHOPE is randomising 240 Europeans with decompensated cirrhosis to 20 mg simvastatin and rifaximin for the prevention of acute-on-chronic liver failure. Second, the European STAT-LIVER trial is randomising 162 patients with Child-Pugh <13 and portal hypertension to receive 10–20 mg of atorvastatin or placebo. The primary endpoint is overall survival. Third, the SACRED trial is hoping to randomise 500 US Veterans with compensated cirrhosis and portal hypertension who lack conventional statin indications to either 40 mg of simvastatin or placebo. Fourth, the NIDDK Liver Cirrhosis Network is also planning a trial of statins.
Beyond statins and NSBB, most data regarding chemoprevention for cirrhosis complications are derived from observational studies. As observational data are susceptible to biases, caution must be applied. For example, aspirin and statins have been associated with biologically implausible risk reductions for incident hepatocellular carcinoma that implicate immortal time bias or misclassification errors.[100,103] Metformin has also been associated with both improved and worsened outcomes, with the largest suggesting no difference in the risk of HCC or decompensation.[104,105] Meta-analyses suggest a large (~50%) reduction of HCC risk with metformin, an unreliable estimate owing to multiple biases, namely immortal time bias.[106–108] One large observational study has evaluated the potential benefits of oral anticoagulants, finding an association with a lower risk of mortality but not specific decompensations raising questions regarding the mechanism and the risk of residual confounding.
Symptom Management in Cirrhosis Care
Patients with cirrhosis experience many physical and psychological symptoms that are often underrecognised, under assessed and undertreated by their clinicians.[110,111] Following is an evidence-based review of pharmacotherapies for the management of common non-pain symptoms encountered in cirrhosis care: pruritus, muscle cramps, sleep disturbances, sexual dysfunction and fatigue (Table 3).
Pruritus. Cholestasis-associated pruritus is a common symptom experienced by patients with cirrhosis, with much of the evidence base for its management coming from trials conducted in patients with cholestatic liver disease.[112–114] Pharmacotherapeutic options for cholestatic pruritus that have been tested in clinical trials include cholestyramine, colesevelam, gabapentin, rifampin, naltrexone, sertraline and bezafibrate. Small randomised studies have established the effectiveness of cholestyramine, a bile acid sequestrant, as a first-line therapeutic agent for the treatment of cholestatic pruritus. While cholestyramine is generally well-tolerated, adverse effects of cholestyramine include drug-drug interactions and gastrointestinal side effects. Colesevelam is a newer bile sequestrant with improved GI tolerability, however, it failed to demonstrate effectiveness in the treatment of cholestatic pruritus in a randomised placebo-controlled trial. Gabapentin was associated with an increase in the perception of itching compared to placebo in a double-blind, randomised, placebo-controlled trial. Rifampin, through its action as a pregnane X receptor agonist, is a second-line therapy with proven effectiveness in treating cholestatic pruritus in multiple randomised controlled trials, however, its risk for hepatotoxicity limits its use in patients with decompensated cirrhosis.[114,118] Naltrexone, an opioid antagonist with established efficacy in treating cholestatic pruritus, can be used as third-line therapy.[33,119,120] Naltrexone should be used with caution in individuals receiving opioid therapy, as it can reduce analgesia or potentiate opioid withdrawal-like reactions. Bioavailability is altered in patients with severe hepatic dysfunction; efficacy and safety estimates may not generalise to multiply decompensated patients. Sertraline, a selective serotonin reuptake inhibitor, has been shown to be a safe and effective treatment for pruritus in a small randomised placebo-controlled trial of 12 patients with chronic liver disease. Lastly, the FITCH trial (fibrates for cholestatic ITCH) demonstrated the effectiveness of bezafibrate, a peroxisome proliferator-activated receptor (PPAR) agonist, in improving moderate to severe pruritus in patients with primary sclerosing cholangitis and primary biliary cholangitis. The effect of other fibrates (eg, fenofibrate) have been examined, albeit in smaller studies.
Muscle Cramps. Muscle cramps are frequently experienced by patients with cirrhosis, affecting over 1 in 3 patients and contributing to poor health-related quality of life.[110,125,126] Despite its high prevalence, there is a paucity of robust clinical trials for the treatment of muscle cramps in patients with cirrhosis, with many published trials limited by small sample sizes. Pharmacological treatments for muscle cramps in patients with cirrhosis include taurine, branched-chain amino acids, quinidine, muscle relaxants (baclofen, methocarbamol and orphenadrine), vitamin E, zinc and L-carnitine. A recently completed trial examined pickle juice sips as a therapy to abort muscle cramps (Clinicaltrials.gov identifier: NCT04650295).
Daily oral taurine supplementation in 30 patients with cirrhosis and muscle cramps led to a reduction in cramp severity, duration and frequency without any reported serious adverse effects in a crossover randomised controlled trial. A multicentre randomised controlled trial of daytime vs nighttime administration of branched-chain amino acids granules in 37 patients with compensated cirrhosis showed a significant reduction in muscle cramping in both groups. A small placebo-controlled randomised controlled trial showed that quinidine treatment improved muscle cramping in 31 patients with cirrhosis. However, the risk of severe hematologic adverse effects of quinidine has restricted its use in the United States.[129,130] Short-term trials of baclofen, methocarbamol and orphenadrine for the treatment of muscle cramps have shown promising efficacy data in single-centre randomised controlled studies, however, larger studies with longer-term follow-up data are needed.[131–133] Daily vitamin E supplementation did not improve muscle cramp symptoms compared to placebo in a pilot randomised controlled crossover trial of 9 patients with cirrhosis. Two open-label studies of L-carnitine supplementation and oral zinc sulphate therapy showed preliminary efficacy in reducing muscle cramps in patients with cirrhosis, however, these trials were limited by small sample sizes and uncontrolled, non-randomised study design.[134,135]
Sexual Dysfunction. Sexual dysfunction is estimated to affect 53%-93% of patients with cirrhosis, occurring in a higher frequency among those with more advanced disease. A randomised controlled trial of a 12-week course of tadalafil therapy for 140 men with cirrhosis (Child-Pugh Turcotte score <10) and erectile dysfunction showed that it enhanced erectile function and improved depression, anxiety and quality of life compared to placebo. Tadalafil was well-tolerated by patients in the trial; there were no significant differences in reproductive hormone levels or body composition between the two groups. There have been no clinical studies of pharmacological treatments for female sexual dysfunction in patients with cirrhosis.
Sleep Disturbances. Sleep disturbances, which include sleep-wake inversion, excessive daytime sleepiness and insomnia, affect 50%–80% of patients with cirrhosis.[110,138–140] Treatment of HE may help to improve sleep disturbances in patients with cirrhosis—an observational study and randomised controlled trial showed the benefit of using lactulose to improve sleep quality in patients with minimal HE.[141,142] Short courses of melatonin, zolpidem and hydroxyzine have also been shown to improve sleep quality in randomised trials of patients with Child Pugh A and B cirrhosis.[143–145] No pharmacological therapies for sleep disturbances have been trialed in patients with decompensated cirrhosis, likely due to the increased risk of cognitive dysfunction and falls in patients with more advanced disease. Similarly, benzodiazepines should be avoided for the management of sleep disturbances in this population given the risk of sedation and HE.[147,148]
Fatigue. Pharmacological therapies for fatigue have primarily been tested in patients with cholestatic liver disease. Fluvoxamine, an antidepressant, showed no beneficial effect on fatigue among patients with cholestatic liver disease in a placebo-controlled randomised clinical trial. Similarly, modafinil, a dopamine reuptake inhibitor, showed no significant impact on fatigue among patients with PBC.[150,151]
Future Directions. Many pharmacological symptom management trials in cirrhosis care have been limited by small sample sizes, single-centre recruitment, lack of long-term follow-up safety data, and non-randomised designs. Minimal data exist for the management of common symptoms such as pain, depression and anxiety in this population. Furthermore, efforts to enrol patients with decompensated cirrhosis are necessary to ensure generalisability of safety and efficacy data. There is also a role for expanding the evaluation of non-pharmacological interventions. For example, evidence-based behavioural therapies such as mindfulness-based stress reduction have shown promising preliminary efficacy for the treatment of sleep disturbances in patients with cirrhosis.
In oncology, routine symptom monitoring has been shown in prospective randomised trials to improve symptom control, quality of life, healthcare utilisation and even survival.[154–156] Routine symptom assessment may lead to early identification of and intervention for untreated symptoms, which may in turn improve health outcomes for patients with cirrhosis. As symptom science continues to expand in cirrhosis care, concurrent attention should be paid to examining the potential role of routine symptom monitoring in clinical care, developing algorithmic approaches to symptom management, and establishing collaborations with supportive care services such as pharmacy, palliative care, psychology, psychiatry and social work.
As the prevalence and complexity of cirrhosis have risen,[1–4] so has the standard of care, the tools available to improve clinical outcomes, and our awareness of gaps in patient-centred outcomes. The needs of patients with cirrhosis may outstrip the capacity of the hepatology workforce to them alone. In this context, in order to optimise the uptake and delivery of the therapies/approaches discussed above, several care delivery strategies must be embraced. First, collaborative models of care are needed. It may not be reasonable to expect generalists to manage the full breadth of cirrhosis-related concerns. Educational seminars and outreach may be helpful but their effect is limited and often fleeting. Instead, hepatology can increase its reach by training advance practice providers (APPs) to semi-specialise or develop shared-care models with hepatologists involved in diagnosis and clinical changes. Second, efforts to prevent cirrhosis complications may require early intervention to treat underlying conditions and initiate prophylactic therapies. The earlier that liver disease is detected, the simpler its management and the more likely its care can be centred within primary care clinics. This requires case finding strategies such as those pioneered by the Veterans Administration (outreach for hepatitis C screening and treatment and linkage to care for cirrhosis),[158,159] screening at-risk persons for hepatitis C, and population-based screening for advanced liver disease. Third, clinics should embrace the use of electronic reporting and monitoring of symptoms. Our group has integrated the assessment of PROs including ascites burden and alcohol use into the electronic record, pushing surveys to patients prior to all visits to objectively track the symptoms and enable early intervention. Others have begun pilots of remote monitoring to track symptoms and vital signs with the capacity to alert care teams when intervention is needed (eg, CirrhoCare: NCT05045924). Fourth, in order to optimise the outcomes of patients with unique needs, structural practice changes may be needed. As we are failing to meet the needs of patients with alcohol use disorder, the solutions are multifold: improve the cross-disciplinary training of hepatologists and co-localise clinics with or streamline referral pathways to addiction specialists. Additionally, given the growing subset of ageing patients with extrahepatic comorbidities, new cross-collaborations with geriatric medicine or palliative care are warranted.
