Foster care, externalizing disorders, and antipsychotic use among Medicaid-enrolled youths.

ABSTRACT: The authors investigated the extent to which clinical diagnoses of externalizing disorders explain higher rates of antipsychotic use by foster care youths.Medicaid claims data from 44 states for 2009 for youths in foster care (N=301,894) and those not in foster care (N=5,092,574) were analyzed, excluding those with schizophrenia, bipolar disorder, autism, and major depressive disorder. Logistic regressions assessed the relationship between foster care, externalizing disorders, and antipsychotic use.Foster care youths had higher rates of externalizing disorders than the comparison group (attention-deficit hyperactivity disorder, 17.3% versus 6.5%; disruptive behavior disorder, 7.2% versus 2.5%; conduct disorder, 2.3% versus .5%) and greater antipsychotic use (7.4% versus 1.4%). Foster care remained a significant predictor of antipsychotic use after control for demographic and diagnostic covariates, including externalizing disorders (adjusted odds ratio=2.59, 95% confidence interval=2.54-2.63).High rates of externalizing disorder diagnoses only partially explained elevated levels of antipsychotic use in this vulnerable population.

Project description:Importance:Urgent care (UC) centers are a growing option to address children's acute care needs, which may cause unanticipated changes in health care use. Objectives:To identify factors associated with high UC reliance among children enrolled in Medicaid and examine the association between UC reliance and outpatient health care use. Design, Setting, and Participants:A retrospective cohort study used deidentified data on 4?133?238 children from the Marketscan Medicaid multistate claims database to calculate UC reliance and outpatient health care use. Children were younger than 19 years, with 11 months or more of continuous Medicaid enrollment and 1 or more UC, emergency department (ED), primary care provider (PCP; physician, advanced practice nurse, or physician assistant; well-child care [WCC] or non-WCC), or specialist outpatient visit during the 2017 calendar year. Statistical analysis was conducted from November 11 to 26, 2019. Exposures:Urgent care, ED, PCP (WCC and non-WCC), and specialist visits based on coded location of services. Main Outcomes and Measures:Urgent care reliance, calculated by the number of UC visits divided by the sum of total outpatient (UC, ED, PCP, and specialist) visits. High UC reliance was defined as UC visits totaling more than 33% of all outpatient visits. Results:Of 4?133?238 children in the study, 2?090?278 (50.6%) were male, with a median age of 9 years (interquartile range, 4-13 years). A total of 223?239 children (5.4%) had high UC reliance. Children 6 to 12 years of age were more likely to have high UC reliance compared with children 13 to 18 years of age (adjusted odds ratio, 1.07; 95% CI, 1.06-1.09). Compared with white children, black children (adjusted odds ratio, 0.81; 95% CI, 0.81-0.82) and Hispanic children (adjusted odds ratio, 0.61; 95% CI, 0.60-0.61) were less likely to have high UC reliance. Adjusted for age, sex, race/ethnicity, and presence of chronic or complex conditions, children with high UC reliance had significantly fewer PCP encounters (WCC: adjusted rate ratio, 0.60; 95% CI, 0.60-0.61; and non-WCC: adjusted rate ratio, 0.41; 95% CI, 0.41-0.41), specialist encounters (adjusted rate ratio, 0.31; 95% CI, 0.31-0.31), and ED encounters (adjusted rate ratio, 0.68; 95% CI, 0.67-0.68) than children with low UC reliance. Conclusions and Relevance:High UC reliance occurred more often in healthy, nonminority, school-aged children and was associated with lower health care use across other outpatient settings. There may be an opportunity in certain populations to ensure that UC reliance does not disrupt the medical home model.

Project description:ObjectiveTo examine the relationship between federally qualified health center (FQHC) use and hospital-based care among individuals dually enrolled in Medicare and Medicaid.Data sourcesData were obtained from 2012 to 2018 Medicare claims.Study designWe modeled hospital-based care as a function of FQHC use, person-level factors, a Medicare prospective payment system (PPS) indicator, and ZIP code fixed effects. Outcomes included emergency department (ED) visits (overall and nonemergent), observation stays, hospitalizations (overall and for ambulatory care sensitive conditions), and 30-day unplanned returns. We stratified all models on the basis of eligibility and rurality.Data extraction methodsOur sample included individuals dually enrolled in Medicare and Medicaid for at least two full consecutive years, residing in a primary care service area with an FQHC. We excluded individuals without primary care visits, who died, or had end-stage renal disease.Principal findingsAfter the Medicare PPS was introduced, FQHC use in rural counties was associated with fewer ED and nonemergent ED visits per 100 person-years among both age-eligible (-14.8 [-17.5, -12.1]; -6.6 [-7.5, -5.6]) and disability-eligible duals (-11.3 [-14.4, -8.3]; -6 [-7.4, -4.6]) as well as a lower probability of observation stays (-0.8 pp age-eligible; -0.4 pp disability-eligible) and unplanned returns (-2.1 pp age-eligible; -1.9 pp disability-eligible). In urban counties, FQHC use was associated with more ED and nonemergent ED visits per 100 person-years (10.6 [8.4, 12.8]; 4.0 [2.6, 5.4]) among disability-eligible duals (a decrease of more than 60% compared with the pre-PPS period) and increases in the probability of hospitalization (1.1 pp age-eligible; 0.8 pp disability-eligible) and ACS hospitalization (0.5 pp age-eligible; 0.3 pp disability-eligible) (a decrease of roughly 50% compared with the pre-PPS period).ConclusionsFQHC use is associated with reductions in hospital-based care among dual enrollees after introduction of the Medicare PPS. Further research is needed to understand how FQHCs can tailor care to best serve this complex population.
