# A Retrospective Analysis of Hepatic Disease Burden and Progression in a Hospital-Based Romanian Cohort Using Integrated Cross-Sectional and Longitudinal Data (2019–2023)

## TL;DR

This study analyzed liver disease patterns in Romania, finding that disease type, age, and sex strongly influence hospitalization and complications.

## Contribution

The study provides insights into how etiology, sex, and age shape liver disease progression and healthcare use in a Romanian cohort.

## Key findings

- CHC patients were predominantly female and older, while ALH and ALC were male-dominated and younger.
- Cirrhotic patients had longer hospital stays, with alcohol-related cirrhosis showing the longest durations.
- Males experienced more severe complications like portal hypertension and ascites compared to females.

## Abstract

Objective: To analyze demographic traits, clinical complications, and healthcare use in patients with chronic liver disease across major etiologies in a large Romanian cohort. Methods: A retrospective study (2019–2023) of 2359 patients with chronic hepatitis C (CHC), hepatitis associated with alcohol (ALH), cirrhosis associated with alcohol (ALC), or non-alcoholic cirrhosis (NALC). Data on demographics, clinical outcomes, and hospitalizations were analyzed using descriptive statistics, regression modeling, and clustering in IBM SPSS 27.0.1. Results: CHC patients were oldest (mean 67.5 ± 12.3 years), while ALH patients were youngest (56.0 ± 11.0 years). CHC prevalence increased with age (10.0% in ≤30-year-olds to 87.1% in ≥81-year-olds; γ = 0.535, p < 0.001). Females comprised 60–70% of CHC cases, males > 85% of ALH and >78% of ALC. Mean hospitalization duration decreased from 13.80 days (2019) to 9.10 days (2023), yet cirrhotic patients had the longest stays (NALC: 16.37 ± 14.34; ALC: 17.66 ± 12.96) versus CHC (10.38 ± 10.14). Etiology was the strongest predictor of hospitalization length. Portal hypertension (PH) was the most common complication (54.3%), with males bearing more severe hepatic complications (ascites—38.3%; PH—66.8%). Conclusions: Hospital-based Romanian cohort analysis revealed that patient presentation and outcomes are fundamentally shaped by the interplay of etiology, sex, and age. We found a distinct female predominance in CHC, a pronounced male predominance in alcohol-related diseases, and evolving trends in non-alcoholic cirrhosis. These determinants dictate specific epidemiological patterns, hospitalization burdens, and complication risks, underscoring the critical need for a paradigm shift toward personalized, etiology-driven, and sex-tailored clinical management.
