Multimorbidity in Patients with Chronic Liver Disease: A Population-Based Study in the EpiChron Cohort, Spain.

: Chronic liver disease (CLD) is highly relevant in clinical practice due to its increasing incidence and associated mortality. We aimed to exhaustively characterize the multimorbidity of patients with CLD. : This is a retrospective observational study of patients aged 18 years and older with a diagnosis of CLD in 2015 in the EpiChron Cohort (Spain). We analyzed the prevalence of comorbidities according to sex and age, conducted a logistic regression analysis with CLD as the independent variable and each of the comorbidities as dependent variables to obtain odds ratios (OR) adjusted for age and sex, and performed an exploratory factor analysis to identify the presence of multimorbidity patterns. : A total of 6836 adults had a diagnosis of CLD (mean age 61.6 years; 62.5% women), with an average of 13 co-existing chronic conditions. Arterial hypertension, lipid metabolism disorders, diabetes, obesity, and musculoskeletal diseases were the most frequent diseases. From the list of 110 chronic conditions analyzed, 75 were systematically associated with CLD, including (OR, 95% confidence interval) chronic pancreatitis (41.2, 33.5-50.6) and inherited metabolic disorders (14.9, 11.8-18.8). Three multimorbidity patterns were identified in both men and women, including cardiovascular, metabolic-geriatric, and mental-substance use, with some differences by sex. : Multimorbidity is the norm in patients with CLD. Our results reveal that a comprehensive and integral approach based on person-centered care, which should take into account their entire spectrum of multimorbidity, is necessary during the care of this type of patient in clinical practice.
