To analyze the associations between Axis II (A2) disorders and two measures of health care utilization with relatively high cost: emergency department () episodes and hospital admissions.
Wave I (2001/2002) and Wave II (2004/2005) of the National Longitudinal Survey on Alcohol and Related Conditions ().
A national probability sample of adults. Gender‐stratified regression analysis adjusted for a range of covariates associated with health care utilization.
The target population of the is the civilian noninstitutionalized population aged 18 years and older residing in the United States. The cumulative survey response rate is 70.2 percent with a response rate of 81 percent ( = 43,093) in Wave I and 86.7 percent ( = 34,653) in Wave II.
Both men and women with A2 disorders are at elevated risk for episodes and hospital admissions. Associations are robust after adjusting for a rich set of confounding factors, including Axis I (clinical) psychiatric disorders. We find evidence of a dose–response relationship, while antisocial and borderline disorders exhibit the strongest associations with both measures of health care utilization.
This study provides the first published estimates of the associations between A2 disorders and high‐cost health care utilization in a large, nationally representative survey. The findings underscore the potential implications of these disorders on health care expenditures.
