ABSTRACT
OBJECTIVE:
To compare characteristics, healthcare resource utilization and costs of Medicaid bipolar disorder (BPD) type I (BP-I) patients with and without frequent psychiatric intervention (FPI).METHODS:
Adults with BP-I, ≥ 1 prescription claim for a mood stabilizer/atypical antipsychotic and 24 months' continuous medical/prescription coverage were identified (MarketScan* Medicaid database). Patients with ≥ 2 clinically significant events (CSEs) during a 12-month identification period had FPI. CSEs included emergency department (ED) visits or hospitalizations with a principal diagnosis of BPD, addition of a new medication to the first observed treatment regimen or ≥ 50% increase in BPD medication dose. Demographic and clinical characteristics were evaluated for the identification period, and healthcare utilization and costs for the 12-month follow-up. Multivariate generalized linear modeling and multivariate logistic regression, respectively, were used to evaluate the impact of FPI on all-cause and psychiatric-related costs and risk of psychiatric-related hospitalization and ED visit during follow-up.RESULTS:
Of 5,527 BP-I patients, 53% had FPI. Relative to patients without FPI, those with FPI were younger and more likely to be female, had higher adjusted all-cause (+US$3,232, p < 0.001) and psychiatric-related (+US$2,519, p < 0.001) costs and higher risk of hospitalization (adjusted odds ratio [OR] = 3.681, 95% confidence interval [CI] = 2.85-4.75) and ED visit (OR = 3.094, 95% CI = 2.55-3.76).LIMITATIONS:
Analysis used a convenience sample of Medicaid enrollees in several geographically dispersed states, limiting generalizability. Analyses of administrative claims data depend on accurate diagnoses and data entry.CONCLUSION:
BP-I patients with FPI incurred significantly higher healthcare resource utilization and costs during the follow-up period than those without FPI.
