Racial Differences in Behavioral Inpatient Diagnosis: Examining the Mechanisms using the 2004 Florida Inpatient Discharge Data

This study used the 2004 Florida Inpatient Discharge Data to examine the existence and the underlying mechanisms of the African American (AA)/white differences in behavioral inpatient diagnosis across a diverse patient population. Findings suggest that discharges of AA patients in Florida were at least twice as likely to have received a primary psychotic vs. affective or substance-related diagnosis, and this held true after between-hospital differences were controlled for. Furthermore, AA (vs. white) race was associated with a ratio of 3.3 in the population rate of hospitalization with a primary psychotic diagnosis, as compared to a ratio of 0.8 and 0.7 for affective and substance-related disorders, respectively. These findings demonstrated the wide existence of racial differences in behavioral inpatient diagnosis and the important role of clinician diagnostic behaviors as opposed to systems-level factors (such as racial differences in access to care and care-seeking behaviors) in leading to observed differences.
