Weekend admissions with ascites are associated with delayed paracentesis: A nationwide analysis of the 'weekend effect'.

INTRODUCTION AND OBJECTIVES: Weekend admissions has previously been associated with worse outcomes in conditions requiring specialists. Our study aimed to determine in-hospital outcomes in patients with ascites admitted over the weekends versus weekdays. Time to paracentesis from admission was studied as current guidelines recommend paracentesis within 24h for all patients admitted with worsening ascites or signs and symptoms of sepsis/hepatic encephalopathy (HE). PATIENTS: We analyzed 70 million discharges from the 2005-2014 National Inpatient Sample to include all adult patients admitted non-electively for ascites, spontaneous bacterial peritonitis (SBP), and HE with ascites with cirrhosis as a secondary diagnosis. The outcomes were in-hospital mortality, complication rates, and resource utilization. Odds ratios (OR) and means were adjusted for confounders using multivariate regression analysis models. RESULTS: Out of the total 195,083 ascites/SBP/HE-related hospitalizations, 47,383 (24.2%) occurred on weekends. Weekend group had a higher number of patients on Medicare and had higher comorbidity burden. There was no difference in mortality rate, total complication rates, length of stay or total hospitalization charges between the patients admitted on the weekend or weekdays. However, patients admitted over the weekends were less likely to undergo paracentesis (OR 0.89) and paracentesis within 24h of admission (OR 0.71). The mean time to paracentesis was 2.96 days for weekend admissions vs. 2.73 days for weekday admissions. CONCLUSIONS: We observed a statistically significant "weekend effect" in the duration to undergo paracentesis in patients with ascites/SBP/HE-related hospitalizations. However, it did not affect the patient's length of stay, hospitalization charges, and in-hospital mortality.

Optimal treatment strategies for hepatic portal venous gas: A retrospective assessment.

BACKGROUND: Hepatic portal venous gas (HPVG) generally indicates poor prognoses in patients with serious intestinal damage. Although surgical removal of the damaged portion is effective, some patients can recover with conservative treatments. AIM: To establish an optimal treatment strategy for HPVG, we attempted to generate computed tomography (CT)-based criteria for determining surgical indication, and explored reliable prognostic factors in non-surgical cases. METHODS: Thirty-four cases of HPVG (patients aged 34-99 years) were included. Necessity for surgery had been determined mainly by CT findings (i.e. free-air, embolism, lack of contrast enhancement of the intestinal wall, and intestinal pneumatosis). The clinical data, including treatment outcomes, were analyzed separately for the surgical cases and non-surgical cases. RESULTS: Laparotomy was performed in eight cases (surgical cases). Seven patients (87.5%) survived but one (12.5%) died. In each case, severe intestinal damage was confirmed during surgery, and the necrotic portion, if present, was removed. Non-occlusive mesenteric ischemia was the most common cause (n = 4). Twenty-six cases were treated conservatively (non-surgical cases). Surgical treatments had been required for twelve but were abandoned because of the patients' poor general conditions. Surprisingly, however, three (25%) of the twelve inoperable patients survived. The remaining 14 of the 26 cases were diagnosed originally as being sufficiently cured by conservative treatments, and only one patient (7%) died. Comparative analyses of the fatal (n = 10) and recovery (n = 16) cases revealed that ascites, peritoneal irritation signs, and shock were significantly more frequent in the fatal cases. The mortality was 90% if two or all of these three clinical findings were detected. CONCLUSION: HPVG related to intestinal necrosis requires surgery, and our CT-based criteria are probably useful to determine the surgical indication. In non-surgical cases, ascites, peritoneal irritation signs and shock were closely associated with poor prognoses, and are applicable as predictors of patients' prognoses.

Oral midodrine is comparable to albumin infusion in cirrhotic patients with refractory ascites undergoing large-volume paracentesis: results of a pilot study.

BACKGROUND AND AIMS: Albumin infusion reduces the incidence of postparacentesis circulatory dysfunction among patients with cirrhosis and tense ascites compared with no treatment. Less costly treatment alternatives such as vasoconstrictors have been investigated, but the results are controversial. Midodrine, an oral α1-adrenergic agonist, increases effective circulating blood volume and renal perfusion by increasing systemic and splanchnic blood pressure. Our aim is to assess whether or not morbidity in terms of renal dysfunction, hyponatremia, systemic, or portal hemodynamics derangement or mortality differed in patients receiving albumin versus midodrine. PATIENTS AND METHODS: Seventy-five patients with cirrhosis and refractory ascites were randomized to receive albumin infusion, oral midodrine for 2 days, or oral midodrine for 30 days after therapeutic large volume paracentesis (LVP). The primary endpoints were development of renal impairment or hyponatremia, change in systemic and portal hemodynamics, cost, and mortality in the short-term and long-term follow-up. RESULTS: No significant difference was found between groups in the development of renal impairment, hyponatremia, or mortality 6 and 30 days after LVP. A significant increase in 24-h urine sodium excretion was noted in the midodrine 30-day group. Renal perfusion improved significantly with the midodrine intake for 30 days only. The cost of midodrine therapy was significantly lower than albumin. CONCLUSION: Midodrine is as effective as albumin in reducing morbidity and mortality among patients with refractory ascites undergoing LVP at a significantly lower cost. Long-duration midodrine intake can be more useful than shorter duration intake in terms of improvement of renal perfusion and sodium excretion.

Cost-Effectiveness of Transjugular Intrahepatic Portosystemic Shunt versus Large-Volume Paracentesis in Refractory Ascites: Results of a Markov Model Incorporating Individual Patient-Level Meta-Analysis and Nationally Representative Cost Data.

PURPOSE: To compare relative cost-effectiveness of serial large-volume paracentesis (LVP) and transjugular intrahepatic portosystemic shunt (TIPS) creation for treatment of refractory ascites. MATERIALS AND METHODS: A decisional Markov model was developed to estimate payer cost and quality-adjusted life-ears (QALYs) associated with LVP and TIPS treatment strategies for cirrhotic patients with refractory ascites. Survival estimates were derived from an individual patient-level meta-analysis of prospective randomized clinical trials. Health utilities for potential health states were derived from a prospective study of patients with cirrhosis. Cost data were derived from national representative claims databases (MarketScan and Medicare) and included reimbursement amounts for relevant procedures, hospitalizations, and outpatient pharmaceutical costs. One-way and probabilistic sensitivity analyses were performed. RESULTS: LVP resulted in 1.72 QALYs gained at a cost of $41,391, whereas TIPS resulted in 2.76 QALYs gained at a cost of $100,538. Incremental cost-effectiveness ratio of TIPS versus LVP was $57,003/QALY. At a willingness-to-pay ratio of $100,000/QALY, TIPS has a 62% probability of being acceptable compared with LVP. CONCLUSIONS: This study suggests that TIPS should be considered cost-effective in a country that places a relatively high value on health improvements but less so in countries with lower levels of health care resources.

Cirrhosis with ascites in the last year of life: a nationwide analysis of factors shaping costs, health-care use, and place of death in England.

BACKGROUND: Liver disease mortality increased by 400% in the UK between 1970 and 2010, resulting in rising pressures on acute hospital services, and an increasing need for end-of-life care. We aimed to assess the effect of demographic, clinical, and health-care factors on costs, patterns of health-care use, and place of death in a national cohort of patients with cirrhosis and ascites in their last year of life. METHODS: We did a retrospective, nationwide analysis of all patients who died from cirrhosis in England between 2013 and 2015, who required large-volume paracentesis in their last year of life. The outcomes measured were health-care costs accrued in the last year of life, number of inpatient days in last year of life, 30-day readmission rate, and occurrence of unplanned hospital death (probability of dying in hospital after unplanned admission). Using generalised linear and logistic regression models, we examined the effect of 12 independent variables on each outcome: sex, ethnicity, age at death, index of multiple deprivation quintile, year of death, liver disease causing death, place of death, time from index presentation in last year of life to death, whether enrolled in a day-case paracentesis service (care group), paracentesis ratio (number of day-case large-volume paracentesis procedures as a proportion of the total number of procedures in the last year of life), number of hospital episodes in the last year of life (not involving large-volume paracentesis), and number of large-volume paracentesis procedures in the last year of life. FINDINGS: Between Jan 1, 2013, and Dec 31, 2015, 13 818 people in England died from liver disease and had large-volume paracentesis within their last year of life. For all patients, mean cost of the last year of life was £21 113 (SD 16 881), 17 888 (52·5%) of 34 068 readmissions occurred within 30 days of discharge, and 10 341 (74·8%) of 13 818 deaths occurred in hospital, of which 10 045 (97·1%) followed an emergency hospital admission. Patients who attended a day-case large-volume paracentesis service within their last year of life had significant reductions in cost (-£4240, 95% CI -4829 to -3651; p<0·0001), number of inpatient bed days (-16·98 days, -18·45 to -15·51; p<0·0001), probability of early readmission (odds ratio [OR] 0·35, 95% CI 0·31 to 0·40; p<0·0001), and probability of dying in hospital after unplanned admission (0·31, 0·27 to 0·34; p<0·0001), compared with patients who had unplanned care. For patients enrolled in day-case services, improvements in outcomes correlated with the proportion of large-volume paracentesis procedures done in a day-case (vs unplanned) setting. INTERPRETATION: The use of day-case large-volume paracentesis services in the last year of life was associated with lower costs, reduced pressure on acute hospital services, and a lower probability of dying in hospital, compared with patients who received exclusively unplanned care in their last year of life. Wider adoption of day-case models of care could reduce costs and improve outcomes in the last year of life. FUNDING: David Telling Charitable Trust.

The benefit of paracentesis on hospitalized adults with cirrhosis and ascites.

BACKGROUND AND AIM: The aim of this study is to assess paracentesis utilization and outcomes in hospitalized adults with cirrhosis and ascites. METHODS: The 2011 Nationwide Inpatient Sample was used to identify adults, non-electively admitted with diagnoses of cirrhosis and ascites. The primary endpoint was in-hospital mortality. Variables included patient and hospital demographics, early (Day 0 or 1) or late (Day 2 or later) paracentesis, hepatic decompensation, and spontaneous bacterial peritonitis. RESULTS: Out of 8 023 590 admissions, 31 614 met inclusion criteria. Among these hospitalizations, approximately 51% (16 133) underwent paracentesis. The overall in-hospital mortality rate was 7.6%. There was a significantly increased mortality among patients who did not undergo paracentesis (8.9% vs 6.3%, P < 0.001). Patients who did not receive paracentesis died 1.83 times more often in the hospital than those patients who did receive paracentesis (95% confidence interval 1.66-2.02). Patients undergoing early paracentesis showed a trend towards reduction in mortality (5.5% vs 7.5%) compared with those undergoing late paracentesis. Patients admitted on a weekend demonstrated less frequent use of early paracentesis (50% weekend vs 62% weekday) and demonstrated increased mortality (adjusted odds ratio 1.12 95% confidence interval 1.01-1.25). Among patients diagnosed with spontaneous bacterial peritonitis, early paracentesis was associated with shorter length of stay (7.55 vs 11.45 days, P < 0.001) and decreased hospitalization cost ($61 624 vs $107 484, P < 0.001). CONCLUSION: Paracentesis is under-utilized among cirrhotic patients presenting with ascites and is associated with decreased in-hospital mortality. These data support the use of paracentesis as a key inpatient quality measure among hospitalized adults with cirrhosis. Future studies are needed to investigate the barriers to paracentesis use on admission.

A Standardized Assessment of Functional Disability Predicts 1-year Mortality in Patients Undergoing Transjugular Intrahepatic Portosystemic Shunt for Refractory Ascites.

GOALS: To determine the association between functional disability and mortality after transjugular intrahepatic portosystemic shunt (TIPS). BACKGROUND: TIPS is a common therapeutic procedure for cirrhotic patients with refractory ascites. The conventional metric for periprocedure risk stratification is the model for end-stage liver disease (MELD), which uses biochemical parameters to predict post-TIPS mortality. It does not account for functional disability. STUDY: This is a retrospective cohort study of 83 patients admitted at an academic liver transplant center with cirrhosis and refractory ascites for the purpose of TIPS placement. We assessed the association of patients' reported activities of daily living (ADL) on a scale of 1 to 21 before TIPS with a primary outcome of 1-year mortality. Multivariable regression to adjust for MELD and Child class was performed. RESULTS: A higher ADL score or functional independence, was associated with decreased 1-year mortality when modeled as both a continuous variable [odds ratio (OR), 0.80; 95% confidence interval (CI), 0.66-0.97; P=0.02) and a dichotomous variable (ADL 21 vs. <21; OR, 0.21; 95% CI, 0.05-0.70; P=0.01). After adjusting for MELD and Child class, functional independence was associated with decreased 1-year transplant-free mortality (OR, 0.22; 95% CI, 0.05-0.77; P=0.02). An ADL score consistent with dependence (<21) was significantly associated with a 3.40-day (95% CI, 1.76-5.04) longer hospital stay, adjusting for MELD and Child class (P<0.0001). CONCLUSIONS: Functional disability is a predictor of post-TIPS mortality and length of stay after controlling for MELD.

Prognostic accuracy of staging systems in patients with primary liver cancer undergoing transarterial chemoembolization.

BACKGROUND/AIMS: To compare the performance of the Child-Turcotte-Pugh (CTP), the Okuda, the Cancer of Liver Italian Program (CLIP), the Barcelona Clinic Liver Cancer (BCLC), the Chinese staging (CS), Chinese university prognostic index (CUPI), Japan integrated staging (JIS), the Tokyo and the French staging systems, in predicting the survival of patients with primary liver cancer (PLC) receiving transarterial chemoembolization (TACE). METHODOLOGY: The clinical data of patients undergoing TACE in our department were retrospectively analyzed and compared with the 9 staging systems based on survival after TACE. RESULTS: A cohort of 60 patients was involved. The survival curves showed that Okuda, BCLC, CS and JIS had better discriminatory ability. By the Cox regression model, Okuda, CS and JIS showed a stronger significance on prognosis. The staging systems with smaller value of -2Ln(L), Akaike Information criterion (AIC) and Schwarz-Bayesian criterion (SBC) were CS, JIS, CLIP and BCLC. An analysis involving 11 factors by Cox model indicated that ascites and vascular invasion were independent prognostic factors. CONCLUSIONS: JIS provides better prognostic stratification for a cohort of the patients with PLC receiving TACE. However, studies with larger samples are still required.

Prognosis assessment of patients with refractory ascites treated with a peritoneovenous shunt.

BACKGROUND/AIMS: We investigated the postoperative outcome and risk factors for DIC and mortality in cases of implanted PVS. METHODOLOGY: We reviewed the cases of 65 patients implanted with PVS from 2000 to 2010. Of these patients, 32 were diagnosed with peritonitis carcinomatosa, 21 had liver cirrhosis with hepatocellular carcinoma (HCC), and 12 had liver cirrhosis without HCC. RESULTS: The postoperative morbidity rate was 18.8%, 76.2%, and 58.3% in cases of peritonitis carcinomatosa, liver cirrhosis with HCC, and liver cirrhosis without HCC, respectively. Early death (within 7 days of surgery) was 7.7% (5/65), and the cause of death in all cases was DIC. Underlying disease, low platelet count, prolongation of prothrombin time (PT), and hyperbilirubinemia were the risk factors for development of DIC, whereas underlying disease, prolongation of PT, hypoalbuminemia, and hyperbilirubinemia were risk factors for early death. Multivariate analysis showed that liver cirrhosis with HCC and prolonged PT were the risk factors for DIC. CONCLUSIONS: Patients with refractory ascites due to liver cirrhosis with HCC and those with prolonged PT should not be considered for PVS.

Prognostic assessment in patients with hepatic encephalopathy.

Hepatic encephalopathy (HE) is a common complication of liver failure that is associated with poor prognosis. However, the prognosis is not uniform and depends on the underlying liver disease. Acute liver failure is an uncommon cause of HE that carries bad prognosis but is potentially reversible. There are several prognostic systems that have been specifically developed for selecting patients for liver transplantation. In patients with cirrhosis the prognosis of the episode of HE is usually dictated by the underlying precipitating factor. Acute-on-chronic liver failure is the most severe form of decompensation of cirrhosis, the prognosis depends on the number of associated organ failures. Patients with cirrhosis that have experienced an episode of HE should be considered candidates for liver transplant. The selection depends on the underlying liver function assessed by the Model for End-stage Liver Disease (MELD) index. There is a subgroup that exhibits low MELD and recurrent HE, usually due to the coexistence of large portosystemic shunts. The recurrence of HE is more common in patients that develop progressive deterioration of liver function and hyponatremia. The bouts of HE may cause sequels that have been shown to persist after liver transplant.

Survival in patients with pancreatic cancer after the diagnosis of malignant ascites or liver metastases by EUS-FNA.

BACKGROUND: The expected survival after the EUS-FNA diagnosis of malignant ascites or liver metastases from pancreatic cancer is not known. OBJECTIVE: To report overall and 1-year survival in these patients. DESIGN: Retrospective cohort series. SETTING: Tertiary referral hospital. PATIENTS: Consecutive subjects with newly diagnosed pancreatic cancer from June 1998 and March 2008 in whom EUS-FNA of the liver or ascitic fluid confirmed hepatic metastases or malignant ascites. INTERVENTIONS: Calculation of survival after diagnosis by using the Social Security Death Index. MAIN OUTCOME MEASUREMENTS: Survival after EUS-FNA diagnosis of stage IV pancreatic cancer. RESULTS: EUS-FNA identified liver metastases and malignant ascites from primary pancreatic cancer in 75 and 13 patients, respectively, and all 88 died during follow-up. For all 88 patients, the 1-year survival rate and median survival were 3.4% (95% CI, 1.1%-10.4%) and 82 days (range 2-754 days), respectively. The 1-year survival rates for those with liver metastases (4.0% [95% CI, 1.3%-12.1%]) and for those with malignant ascites (0% [95% CI, 0-24.7%]) were similar (P = 1.0). The median survival for patients with liver metastases of 83 days (range 2-754 days) was similar to that for those with malignant ascites (64 days; range 2-153 days) (P = .13). No clinical variable considered predicted survival of more than, less than, or 3 months. LIMITATIONS: Retrospective series with variable treatment for malignancy. CONCLUSIONS: In patients with pancreatic cancer, identification of malignant ascites or liver metastases by EUS-FNA is associated with a very poor prognosis.

Transjugular intrahepatic portosystemic shunt in the management of ascites and hepatorenal syndrome.

Ascites is the most common complication of liver cirrhosis and when it develops mortality is 50% at 5 years, apart from liver transplantation. Large volume paracentesis has been the only option for ascites refractory to medical treatment. The role of transjugular intrahepatic portosystemic shunt in the management of diuretic-resistant ascites has been evaluated in many cohort studies and five randomized trials up to now, clearly showing improvement in natriuresis and clinical efficacy. It, however, remains unclear how transjugular intrahepatic portosystemic shunt affects survival and quality of life, because hospital admissions owing to worsening encephalopathy may counterbalance the reduced need of paracentesis. What is clear is that the patient selection is critical. About 30% of patients with ascites develop hepatorenal syndrome at 5 years, leading to high mortality in its severe and progressive form. As its main pathogenetic factor is derangement of circulatory function owing to portal hypertension, these patients may benefit from transjugular intrahepatic portosystemic shunt, but this has been shown only in small series, in which mortality remains very high, owing to the underlying poor liver function.

Comparison between handgrip strength, subjective global assessment, and prognostic nutritional index in assessing malnutrition and predicting clinical outcome in cirrhotic outpatients.

OBJECTIVE: This study compared three methods of assessing malnutrition in cirrhotics and correlated nutritional status with clinical outcome. METHODS: This cross-sectional study evaluated nutritional status by subjective global assessment (SGA), prognostic nutritional index (PNI), and handgrip strength (HG) in outpatients with cirrhosis (n = 50) and two control groups with hypertension (n = 46) and functional gastrointestinal disorders (n = 49). Patients with cirrhosis were followed for 1 y to verify the incidence of major complications, the need for transplantation, and death. RESULTS: Among patients with cirrhosis, 88% were Child-Pugh A and only 12% were Child-Pugh B. Among these, prevalences of malnutrition were 28% by SGA, 18.7% by PNI, and 63% by HG (P < 0.05). HG, but not SGA or PNI, predicted a poorer clinical outcome in patients with cirrhosis because major complications such as uncontrolled ascites, hepatic encephalopathy, spontaneous bacterial peritonitis, and hepatorenal syndrome developed in 65.5% of malnourished patients versus 11.8% of well-nourished ones (P < 0.05). No significant differences by any method were seen between the two groups regarding liver transplantation or death. CONCLUSIONS: There was a high prevalence of malnutrition in cirrhotic outpatients, especially when assessed by HG, which was superior to SGA and PNI in this study. HG was the only technique that predicted a significant incidence of major complications in 1 y in undernourished cirrhotic patients.

Persistent ascites and low serum sodium identify patients with cirrhosis and low MELD scores who are at high risk for early death.

Despite the adoption of "sickest first" liver transplantation, pretransplant death remains common, and many early deaths occur despite initially low Model for End-stage Liver Disease (MELD) scores. From 1997-2003, we studied 507 cirrhotic United States veterans referred for consideration of liver transplantation to identify additional predictors of early mortality. Most of the patients were male (98%) with cirrhosis caused by hepatitis C and/or alcohol (88%). Data for 296 patients referred prior to February 27, 2002 (training group), were analyzed; findings were validated in 211 patients referred subsequently (validation group). In the training group, 61 patients (21%) died within 180 days without transplantation; their median initial MELD score was 21. MELD score, persistent ascites, and low serum sodium (<135 meq/L) were independent predictors of early mortality. In patients with a MELD score of less than 21, only low serum sodium and persistent ascites were independent predictors of mortality; for MELD scores above 21, only MELD was independently predictive. Prognostic significance of persistent ascites and low serum sodium for low MELD score patients was confirmed in the validation group. Risk varied continuously with worsening hyponatremia. Modifying MELD, by including points for persistent ascites and low serum sodium, improved prediction of early pretransplant mortality in low MELD score patients. In conclusion, persistent ascites and low serum sodium identify patients with cirrhosis with high mortality risk despite low MELD scores. Ascites, hyponatremia, and other findings indicative of hemodynamic decompensation merit further prospective study as prognostic indicators in patients awaiting liver transplantation, and should be considered in setting minimal listing criteria.

Peritoneovenous shunts in patients with intractable ascites: palliation at what price?

Intractable ascites carries great morbidity by affecting appetite, mobility, and quality of life. Peritoneovenous shunts (PVSs) are utilized to abate intractable ascites, although long-term efficacy is unestablished. Thirty male and 18 female cirrhotics, 55 +/- 12 (standard deviation) years of age, failed multiple large-volume paracenteses and diuretic therapy before undergoing PVS. Data were collected until death or the present time. Nine patients (19%) are alive and palliated, four with working shunts [average follow-up (ave. f/u), 30 months] and five without shunts (ave. f/u, 19 months). Thirty-two (67%) patients died: 18 palliated with functional shunts (survival time, 4.4 +/- 5.7 months), 8 unpalliated with dysfunctional shunts (ave. f/u, 3.9 +/- 4.5 months), 4 unpalliated with shunts removed (ave. f/u 5.5 +/- 4.7 months), and 2 with unknown shunt function at death. Function was lost to occlusion in 26 patients, infection in 9, and ligation for disseminated intravascular coagulation in 3. Thirteen patients underwent 18 shunt replacements. At death/present time, 22 (46%) patients were palliated with functioning shunts. Seven patients were lost to follow-up. PVSs provide palliation for intractable ascites short term, but commonly occlude within 1 year. Despite palliation, complications with PVSs are high, and survival is limited.

Salt or no salt in the treatment of cirrhotic ascites: a randomised study.

To compare the effect of diet, cirrhotic patients with ascites were randomised into two treatment groups: (1) a low sodium diet (21 mmol) per day or (2) an unrestricted sodium intake. Both groups received effective doses of diuretics (spironolactone or, if necessary, spironolactone and furosemide. One hundred and forty patients from 12 liver units were included according to well defined criteria (group 1: 76; group 2: 64). After an initial four to seven day period of bed rest and salt restriction (21 mmol sodium pd), randomisation was done in each centre. We saw no significant difference between the two groups with respect to clinical and biochemical data; mortality or withdrawal (definitive or temporary) because of biochemical disturbances (group 1: 34%, group 2: 22%); the time for complete disappearance of ascites was significantly shorter (p = 0.014) for the salt restricted patients actuarial survival (curves plotted up to the 120th day) was not statistically different (p = 0.18), but division into subgroups using various prognostic factors showed that survival was significantly better for salt restricted patients without previous gastrointestinal bleeding (p = 0.02); hospitalisation time and costs were identical in both groups. We conclude that the advantage of a normal salt diet was not shown in this study.
