Second-generation antipsychotic use among stimulant-using children, by organization of medicaid mental health.

ABSTRACT: Reducing overuse of second-generation antipsychotics among Medicaid-enrolled children is a national priority, yet little is known about how service organization affects use. This study compared differences in second-generation antipsychotic utilization among Medicaid-enrolled children across fee-for-service, integrated managed care, and managed behavioral health carve-out organizational structures.Organizational structures of Medicaid programs in 82 diverse counties in 34 states were categorized and linked to child-level cross-sectional claims data from the Medicaid Analytic Extract covering fiscal years 2004, 2006, and 2008. To approximate the population at risk of antipsychotic treatment, the sample was restricted to stimulant-using children ages three to 18 (N=419,226). The sample was stratified by Medicaid eligibility group, and logistic regression models were estimated for probability of second-generation antipsychotic use. Models included indicators of county-level organizational structure as main predictors, with sequential adjustment for personal and county-level covariates.With adjustment for person-level covariates, second-generation antipsychotic use was 31% higher among youths in foster care in fee-for-service counties than for youths in counties with carve-outs (odds ratio [OR]=1.69, 95% confidence interval [CI]=1.26-2.27). Foster care youths in integrated counties had the second highest adjusted odds (OR=1.31, CI=1.08-1.58). Similar patterns of use also were found for youths eligible for Supplemental Security Income but not for those eligible for Temporary Assistance for Needy Families. Differences persisted after adjustment for county-level characteristics.Carve-outs, versus other arrangements, were associated with lower second-generation antipsychotic use. Future research should explore carve-out features (for example, tighter management of inpatient or restricted access, as well as care coordination) contributing to lower second-generation antipsychotic use.

Project description:BackgroundTo examine the baseline metabolic monitoring (MetMon) for second generation antipsychotics (SGA) among patients with schizophrenia in the Veterans Integrated Service Network (VISN) 16 of the Veterans Health Administration (VHA).MethodsVISN16 electronic medical records for 10/2002-08/2005 were used to identify patients with schizophrenia who received a new episode of SGA treatment after 10/2003, in which the VISN 16 baseline MetMon program was implemented. Patients who underwent MetMon (MetMon+: either blood glucose or lipid testing records) were compared with patients who did not (MetMon-), on patient characteristics and resource utilization in the year prior to index treatment episode. A parsimonious logistic regression was used to identify predictors for MetMon+ with adjusted odds ratios (OR) and 95% confidence intervals (CI).ResultsOut of 4,709 patients, 3,568 (75.8%) underwent the baseline MetMon. Compared with the MetMon- group, the MetMon+ patients were found more likely to have baseline diagnoses or mediations for diabetes (OR [CI]: 2.336 [1.846-2.955]), dyslipidemia (2.439 [2.029-2.932]), and hypertension (1.497 [1.287-1.743]), substance use disorders (1.460 [1.257-1.696]), or to be recorded as obesity (2.052 [1.724-2.443]). Increased likelihood for monitoring were positively associated with number of antipsychotics during the previous year (FGA: 1.434 [1.129-1.821]; SGA: 1.503 [1.290-1.751]). Other significant predictors for monitoring were more augmentation episodes (1.580 [1.145-2.179]), more outpatient visits (1.007 [1.002-1.013])), hospitalization days (1.011 [1.007-1.015]), and longer duration of antipsychotic use (1.001 [1.001-1.001]). Among the MetMon+ group, approximately 38.9% patient had metabolic syndrome.DiscussionThis wide time window of 180 days, although congruent with the VHA guidelines for the baseline MetMon process, needs to be re-evaluated and narrowed down, so that optimally the monitoring event occurs at the time of receiving a new episode of SGA treatment. Future research will examine whether or not patients prescribed an SGA are assessed for metabolic syndrome following the index episode of antipsychotic therapy, and whether or not such baseline and follow-up monitoring programs in routine care are cost-effective.ConclusionThe baseline MetMon has been performed for a majority of the VISN 16 patients with schizophrenia prior to index SGA over the study period. Compared with MetMon- group, MetMon+ patients were more likely to be obese and manifest a more severe illness profile.
