OBJECTIVES: This is an exploratory analysis of ambulatory and inpatient services utilization by older persons with type I bipolar disorder experiencing elevated mood. The association between type of treatment setting and the person''s characteristics is explored within a framework that focuses upon predisposing, enhancing, and need characteristics. METHOD: Baseline assessments were conducted with the first 51 inpatients and 49 outpatients 60 years of age and older, meeting criteria for type I bipolar disorder, manic, hypomanic, or mixed episode enrolled in the geriatric bipolar disorder study (GERI-BD) study. We compared participants recruited from inpatient versus outpatient settings in regard to the patients'' predisposing, enabling, and need characteristics. RESULTS: Being treated in an inpatient rather than an outpatient setting was associated with the predisposing characteristic of being non-Hispanic caucasian (odds ratio [OR]: 0.1; P = .005) and past history of treatment with first-generation antipsychotics (OR: 6.5; P < .001), and the need characteristic reflected in having psychotic symptoms present in the current episode (OR: 126.08; P < .001). CONCLUSION: Ethnicity, past pharmacologic treatment, and current symptom severity are closely associated with treatment in inpatient settings. Clinicians and researchers should investigate whether closer monitoring of persons with well-validated predisposing and need characteristics can lead to their being treated in less costly but equally effective ambulatory rather than inpatient settings.
