Background: Hepatic encephalopathy (HE) is an adverse prognostic indicator of liver cirrhosis, often triggered by various precipitating factors, with gastrointestinal bleeding being the most common. Comparing the Child–Pugh and Model for End-Stage Liver Disease (MELD) scores to predict the severity and outcome of complications in patients with cirrhosis could help establish an accurate prognosis.
Methods: We retrospectively reviewed the records of patients with cirrhosis aged 18 and older who were referred to the Gastroenterology Department at Imam Khomeini Hospital in Ahvaz from April to September 2023. A statistical analysis was conducted to compare MELD and Child-Pugh score (CPS) in 95 patients with cirrhosis.
Results: The in-hospital mortality rate was strongly correlated with certain complications of cirrhosis. Gastrointestinal bleeding and HE showed statistical significance (P < 0.05). Additionally, the co-occurrence of cirrhosis complications, particularly HE in conjunction with others, was associated with increased mortality rates. Abnormal levels of the international normalized ratio, prothrombin time, partial thromboplastin time, bilirubin, and liver enzymes (alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase) were also associated with mortality (P < 0.05). Specific laboratory factors in ascites fluid, namely total cell count and red blood count, were linked to the 6-month survival rate (P < 0.05). Furthermore, CPS was identified as a more specific and sensitive independent predictor of 6-month in-hospital survival than the MELD score (logistic regression: odds ratio, 2.3; standard error, 0.0189; P < 0.05).
Conclusion: We recommend continuing to use the CPS for predicting in-hospital mortality in patients with cirrhosis and for the individual evaluation of liver disease in daily clinical practice.

Cirrhosis represents the final stage of chronic liver disease. As the disease progresses from the compensation phase to the decompensation phase, patients experience a range of complications that significantly worsen their life expectancy.1 Clinically, cirrhosis is categorized into two phases: the early or compensated phase, which is often asymptomatic, and the subsequent decompensated phase.2 Due to the poor survival rates among patients with decompensated cirrhosis and the worsening prognosis associated with complications such as hepatic encephalopathy (HE), gastrointestinal bleeding (GIB), spontaneous bacterial peritonitis (SBP), hepatorenal syndrome (HRS), and ascites, researchers are motivated to develop reliable tools for predicting outcomes in patients with chronic liver disease.3–5
The Child-Pugh score (CPS) and the Model for End-Stage Liver Disease (MELD) score are widely used disease severity scoring systems in patients with cirrhosis.6,7 Introduced in 1964, the CPS has become a reliable tool for the clinical evaluation of liver dysfunction.8 The MELD score, introduced in 2002 in the USA, initially included the etiology of liver cirrhosis in its calculations. However, the current version of the MELD score utilizes paraclinical parameters such as serum bilirubin, creatinine levels, and prothrombin time (PT) or international normalized ratio (INR).9,10 Originally developed to predict mortality in patients undergoing transjugular intrahepatic portosystemic shunt (TIPSS) procedures, the MELD score is now primarily used to prioritize organ allocation for liver transplantation candidates.11,12
Given the rising number of patients with cirrhosis experiencing poor survival rates during the decompensated phase, as well as increased hospital admissions due to overt HE and GIB, it is clear that these complications are common and associated with high resource use and significant mortality. Consequently, establishing an accurate prognosis for these patients continues to be a challenging issue.13,14 Therefore, we aimed to investigate this issue by comparing the accuracy of the CPS and the MELD scoring systems in predicting in-hospital mortality in patients with complications from liver cirrhosis.
After receiving approval from the Ethics Committee of Ahvaz Jundishapur University of Medical Sciences (Ethics Committee number: IR.AJUMS.REC.A/1402), 95 patients aged 18 years and older with liver cirrhosis were retrospectively included in this study. These patients were referred to the Gastroenterology Department of Imam Khomeini Hospital in Ahvaz between April and September 2023. Since the current investigation was a retrospective study, written informed consent to participate in this study was waived by the Ahvaz Jundishapur University of Medical Sciences ethics committee.
Each hospital record was meticulously reviewed to confirm the diagnosis of liver cirrhosis and to gather all pertinent data, which was derived from a well-established combination of laboratory, clinical, anatomopathological, and radiological features.
1. Standard parameters of liver and kidney function were evaluated.
2. The CP and MELD scores (the MELD score was calculated according to the standard formula) were assessed and compared.
The etiology of liver disease varied, with cases attributed to cryptogenic factors, hepatitis C virus, hepatitis B virus, alcohol abuse, and potentially other reasons.
The data recorded at admission included demographic data (age, sex), the natural history of cirrhosis {etiology, the presence of ascites, upper GIB, hepatocellular carcinoma (HCC), SBP, HRS, and HE, the cause of admission and laboratory measurements (platelet and leukocyte count, bilirubin, hemoglobin, hematocrit, creatinine, albumin, and levels of liver enzymes; alanine aminotransferase [ALT], aspartate aminotransferase [AST], alkaline phosphatase [ALK-P], PT, and INR)}.
All biochemical evaluations were conducted by the same laboratory. Prothrombin activity was initially assessed by a single operator and expressed as a percentage. It was then converted to the PT and INR using the laboratory’s internal standards.
We also collected endoscopic findings from 61% of patients with cirrhosis, at the discretion of their physicians. The most frequently recorded endoscopic parameter was esophageal varices. Additionally, we documented in-hospital deaths and their causes. The endpoint of this 6-month study was either the discharge of the patient or death, which was used to predict in-hospital mortality among hospitalized patients with decompensated cirrhosis.
The severity of liver cirrhosis was assessed using both the CPS and the MELD scoring systems. The calculation of the CPS took into account the severity of ascites, HE, INR, total bilirubin, and albumin levels.15 The MELD score was calculated according to the following standard formula:
3.8 × loge [bilirubin (mg/dL)] + 11.2 × loge (INR) + 9.6 × loge [creatinine (mg/dL)] + 6.4 × (etiology: 0 if cholestatic or alcoholic, 1 otherwise).16
Both the MELD and CPS scores were calculated based on parameters obtained at the time of referral. The areas under the receiver operating characteristic (ROC) curves, along with 95% confidence intervals (CI), were reported for these two scoring systems.
Categorical variables were reported as frequency (percentage), and Fisher’s exact test or the chi-square test was used to compare these variables. Statistical differences and the analysis of quantitative data were determined using the independent-sample
All patients with cirrhosis admitted to the Gastroenterology Department of Imam Hospital between April and September 2023 were enrolled in the study.
The mean age of the population was 56 years, with 62 individuals (65%) being male and 33 female (35%). The predominant etiology was cryptogenic, accounting for 48% of cases. The characteristics of the patients included in this study are summarized in Table 1.

Ninety-five individuals were diagnosed with cirrhosis. Following a six-month observation period, 18 of these patients died (18.9%). The occurrence of complications related to liver cirrhosis, particularly the co-occurrence of HE with other complications, was associated with the in-hospital mortality rate (Table 3).

Among the 66 patients who underwent endoscopy, esophageal varices were the most frequently observed condition, accounting for 73.3% of cases. The incidences of high-grade and low-grade varices were roughly equal. Nevertheless, there was no evidence of a relation between endoscopic findings and the in-hospital mortality rate.
An analysis of the background of the 77 patients who survived and 18 who died reveals that smoking is a significant risk factor affecting the survival of patients with cirrhosis (
According to Table 7, the current results demonstrate a strong correlation between CPS and MELD scores and the in-hospital mortality rate. The accuracy of CPS and MELD in predicting in-hospital mortality among hospitalized patients showed no statistically significant difference.

Receiving blood, plasma, packed cells (PCs), and fresh frozen plasma (FFP), as well as requiring admission to the intensive care unit (ICU), all displayed correlations with the in-hospital mortality rate. However, the total duration of hospital admission did not influence the survival outcomes of patients with cirrhosis (
In the ROC analysis, the CPS had a cut-off value 10.5, with a specificity of 71.1% and a sensitivity of 86.6% (Fig. 1A). The MELD score had a cut-off value of 22, with a specificity of 68% and a sensitivity of 79% (Fig. 1B).
Logistic regression analysis identified CPS as a single independent predictor of 6-month in-hospital survival, demonstrating greater specificity and sensitivity than the MELD score (Logistic regression: OR = 2.3, standard error = 0.0189;
HE and GIB are among the most severe complications associated with liver cirrhosis, potentially leading to death if not properly managed.17,18
HE, a major complication of cirrhosis, can manifest in a range from subclinical alterations to coma. It is classified into three types: Type A results from acute liver failure; Type B is caused by portal-systemic shunting without intrinsic liver disease; and Type C occurs in patients with underlying cirrhosis.19,20
The development of a GIB episode significantly contributes to morbidity and mortality among patients with liver cirrhosis. This may be associated with various factors including the degree of liver dysfunction (as indicated by CPS and MELD scores), the bleeding source (such as esophageal or gastric varices, gastric or duodenal ulcers, hemorrhagic gastritis, esophagitis, or Mallory-Weiss syndrome), characteristics of the bleeding (including severity and presentation form), compensated status, concurrent HCC, and the presence of other underlying conditions.21,22
This study analyzed the complications most closely associated with mortality, including HE and GIB, in patients with liver cirrhosis. It focused on the relationship between these complications and the severity of liver dysfunction, as assessed by the CPS and MELD scoring systems.
This study included 95 patients with cirrhosis aged over 18 years; among them, 25.30% exhibited HE, and 38.90% experienced GIB. During the 6-month study period, 18 patients (19%) died. The most significant finding was the strong correlation between the in-hospital mortality rate and certain complications of cirrhosis, such as HE (42.90% mortality,
The cause of death for all patients was linked to the occurrence of three simultaneous liver cirrhosis complications, resulting in a mortality rate of 100%. The concurrent presence of HE, GIB, and HRS in patients was notably infrequent, likely reflecting advancements in prevention and improved management of these complications.26 However, when these complications do co-occur, they can lead to catastrophic outcomes in patients with cirrhosis, with a mortality rate of 100%. The current study indicated that ascites (73.70%), SBP (57.9%), and GIB (38.90%) were the most prevalent complications observed in patients with cirrhosis. The co-occurrence of these complications with HE is particularly lethal, with a mortality rate of 100%. GIB creates an environment conducive to bacterial infections in ascitic fluid, thereby establishing a connection between GIB and SBP. SBP, an infection of the ascitic fluid, is now recognized as a severe bacterial infection that can lead to renal failure in patients with cirrhosis.27 Renal failure development is strongly associated with a very poor short-term prognosis.28 Factors independently predictive of renal failure include the severity of bleeding, as evidenced by hypovolemic shock and high blood transfusion requirements.27,29
Another important finding was the relationship between laboratory markers in ascitic fluid (total cell and RBC count) and the in-hospital mortality rate in patients with cirrhosis. Previous studies have indicated that a RBC count of 10,000 cells/mL or greater characterizes hemorrhagic ascites, which is associated with increased morbidity and mortality. In patients with liver cirrhosis, hemorrhagic ascites may result from acute or chronic hemorrhage due to ruptured lymphatics or varices, a ruptured HCC lesion, or leakage from the splanchnic vascular bed. Consequently, the occurrence of hemorrhagic ascites often necessitates extensive blood transfusions.30,31 Over time, these conditions can lead to patient death. Our findings concur with these observations and demonstrate that the volume of blood, plasma, PCs, and FFP received, along with the need for ICU admission, all correlated positively with the in-hospital mortality rate. It is likely that the need for blood is driven by severe complications such as renal failure or hemorrhagic ascites. Therefore, our results, although seemingly promising, actually reflect critical conditions and fatal outcomes in surviving patients with cirrhosis.
This study also demonstrated positive correlations between INR, PT, PTT, bilirubin, liver enzymes (ALT, AST, and ALK-P), and the in-hospital mortality rate. These findings are reasonable based on the definition of the MELD and CPS32,33 and the fact that these serum markers are considered to be criteria for assessing the severity of liver cirrhosis.34,35
A prognostic evaluation of patients with liver cirrhosis is crucial for the decision-making process in clinical settings, but it presents a significant challenge for clinicians. In this context, the CPS and the MELD offer tools to more accurately assess the severity of liver disease and identify patients with cirrhosis at risk of mortality.8,9 The CPS is a vital prognostic scoring system for patients with cirrhosis and plays a key role in the current organ allocation policy. However, the traditional model has several limitations, including the subjectivity of some parameters and its inadequate ability to discriminate in long-term prognosis.36 Subsequently, the MELD scoring system was developed to assess the prognosis of patients undergoing TIPSS procedures and was later extended to evaluate short-term survival in patients at various stages of liver cirrhosis.
Several studies have shown that the MELD score performs at least as well as the CPS in predicting patient outcomes.37–39 However, other investigations have produced contrasting results. One prospective study enrolled 110 consecutive patients with decompensated cirrhosis of the liver, identified either clinically or radiologically. The hospital monitored these patients throughout their stay. Initially, patients were categorized into groups A, B, and C based on the CPS. The MELD score was also calculated for each patient. The study’s endpoints were the length of hospital stay and the rate of in-hospital mortality. The findings indicated that the MELD score did not surpass the CPS in predicting the short-term prognosis of patients with cirrhosis.40 Consistent with these findings, another prospective study assessed the CPS and recalibrated CPS, along with the MELD score at admission, to evaluate their effectiveness in distinguishing between rebleeding and death in the hospital. This study found that the recalibrated CPS, original CPS, and MELD score were effective indicators for predicting in-hospital mortality among patients with bleeding esophageal varices due to alcoholic cirrhosis.41 In a recent study conducted by a tertiary healthcare center in India, the CPS, MELD, and MELD-Na scores of 171 patients with end-stage liver disease were obtained upon admission. The C-statistics of the three scores for predicting 3-month mortality were evaluated and compared. The results demonstrated that the CPS, MELD, and MELD-Na scores all had excellent predictive power for mortality at 3 months. Among these, the CPS was found to be the most accurate in predicting 3-month mortality.42
In this study, we compared the prognostic abilities of the CPS and the MELD score in assessing the 6-month survival prognosis for patients with cirrhosis. The CPS demonstrated discriminative ability between patients who survived and those who died within the 6-month study period, exhibiting excellent diagnostic accuracy in predicting short-term survival. In contrast, some studies have suggested that the MELD scoring system has greater prognostic ability for the survival of patients with liver cirrhosis.43 The rationale for this claim is that the MELD model lacks many of the limitations of the CPS and is a well-recognized predictor of survival in patients with liver disease44 and outcomes post-liver transplantation.45 Additionally, it includes the serum creatinine level, which measures renal function in patients with liver disease.44 However, some researchers advocate for further improvements to the MELD model, such as the inclusion of sodium levels — termed “Sodium-MELD” or “MELD-Na” — which may provide a distinct advantage over the CPS.46–48 Moreover, some studies question whether MELD is superior to CPS in predicting survival in patients with chronic liver disease. They propose that using both MELD and CPS as complementary tools could be beneficial in evaluating the progressive worsening of the clinical condition in patients with cirrhosis.38,43,49
In Conclusion, the MELD scoring system utilizes bilirubin, INR, and creatinine levels, whereas the CPS incorporates clinical complications such as HE and ascites, along with para-clinical findings. Indeed, both the CPS and MELD scores have their own significance. However, our results indicate that the CPS is a more accurate predictor of in-hospital mortality in patients with cirrhosis. The CPS also demonstrates greater effectiveness as a tool for assessing long-term prognosis, especially in a broad context. Therefore, we advocate for the continued use of the CPS in the routine clinical assessment of individual liver diseases. Furthermore, the predictive accuracy of both the CPS and the Meld score could be enhanced by including variables that reflect the circulatory dysfunction seen in cirrhotic liver disease. This could lead to the development of a new scoring system that offers a more precise and reliable method for evaluating the prognosis of patients with liver disease.
