Abstract:
Examine differences in treatment patterns among Blacks and non-Blacks in the U.S. Schizophrenia Care and Assessment Program. Baseline data from medical record abstraction, participant self-report and clinical assessment used to examine differences by race (race-gender pairings) (n = 2,239). Descriptive and multivariate (logistic) analysis employed. More Blacks were diagnosed with paranoid subtype. Blacks exhibited a more negative PANSS composite score, lower quality of life scores, and higher AIMS scores than non-Blacks. There was no statistically significant difference in the number of outpatient visits or inpatient admissions between Blacks and non-Blacks. Blacks had lower medication adherence and received less second-generation agents and more antiparkinson/anticholinergic agents. Proportion of Black males receiving depot was greater than other race-gender pairings. Regression results indicate Blacks more likely to be prescribed only first-generations after controlling for depot (OR = 1.64; CI = 1.27-2.12; p = 0.0002). Schizophrenia is, on average, accompanied by different diagnoses and symptoms in Blacks. Symptom profiles indicate that second-generation antipsychotics may be underprescribed to Black patients.

Crossover Experiments
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.
