Chronic Liver Disease-Associated Hospitalizations among Adults with Diabetes,National Inpatient Sample,2001–2012

Abstract

Objective.

Many people with diabetes have a variety of diabetes-related complications. Among the variety of conditions associated with diabetes, however, liver diseases are less well recognized. As such, we aimed to describe chronic liver disease (CLD)-associated hospitalization rates among U.S. adults with diabetes from 2001–2012.

Methods.

We used a nationally representative database of hospitalizations, the National Inpatient Sample, to determine CLD-associated hospitalization rates among U.S. adults aged ≥18 years with and without diabetes, from 2001–2012. Hospitalizations listing an International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) code for CLD on the discharge record were selected for analysis and were further classified by diabetes status based on concurrent presence of a diabetes ICD-9-CM code. We calculated average annual age-adjusted hospitalization rates and 95% confidence intervals (CIs), and conducted a test for trend.

Results.

For 2001–2012, the total age-adjusted CLD-associated hospitalization rate among adults with diabetes (1,680.9 per 100,000 population; 95% CI 1,577.2, 1,784.6) was approximately four times the rate of adults without diabetes (424.2 per 100,000 population; 95% CI 413.4, 435.1). Total age-adjusted hospitalization rates of adults with and without diabetes increased 59% and 48%, respectively, from 2001–2002 to 2011–2012 (p<0.001). Hepatitis C- and chronic hepatitis and cirrhosis-associated hospitalizations comprised the largest proportion of total CLD-associated hospitalizations among adults with and without diabetes.

Conclusion.

Providers should be aware of the potential existence of CLD among adults with diabetes and counsel patients on preventive methods to avoid progressive liver damage.
