Missed and Delayed Diagnoses of Chronic Liver Disease in Primary Care Patients with Cirrhosis.

ABSTRACT

BACKGROUND: Chronic liver diseases (CLD), cirrhosis, and hepatocellular carcinoma (HCC) cause significant morbidity and mortality. Unfortunately, patients with CLD often go undiagnosed until progression to cirrhosis and HCC. We aimed to determine the proportion of primary care patients with severe liver disease outcomes that had missed or delayed CLD diagnoses. METHODS: This retrospective cohort study evaluated primary care patients with a diagnosis of cirrhosis, HCC, or other severe liver disease outcome between 2012 and 2021. The outcomes of interest were missed and delayed diagnoses of CLD, defined as the absence of a CLD diagnosis (missed) or first appearance of CLD on the same day as the cirrhosis diagnosis (delayed). Univariate analyses were performed to describe the cohort. Multivariable logistic regression models analyzed the association of aminotransferase elevations with the outcomes of interest. RESULTS: Of 667 patients with cirrhosis or HCC, 133 (20%) had a missed CLD diagnosis, and 243 (36%) had a delayed CLD diagnosis. Alcohol-related liver disease was the most common etiology among patients with missed/delayed diagnoses. A lower proportion of patients with missed/delayed diagnoses had an elevation in ALT or AST compared to patients with timely diagnoses (61% vs. 77%, p < 0.001). Elevated aminotransferase values were associated with lower odds of a missed/delayed diagnosis (OR 0.47; 95%CI 0.34-0.66). CONCLUSIONS: Most patients with cirrhosis or HCC had missed or delayed diagnoses of CLD in the context of probable overreliance on aminotransferase elevation for CLD detection. Enhanced screening for high prevalence CLD, especially alcohol, in primary care is needed.
