Longitudinal Trends in the Diagnosis of Attention-Deficit/Hyperactivity Disorder and Stimulant Use in Preschool Children on Medicaid.

OBJECTIVES: To describe trends in the diagnosis of attention-deficit/hyperactivity disorder (ADHD) and prescribing of stimulants in preschool-age children receiving Medicaid and to identify factors associated with the receipt of psychosocial care. STUDY DESIGN: Data were extracted from 2012-2016 Kentucky Medicaid claims for children aged <6 years. ADHD was identified using International Classification of Diseases, Tenth Revision codes F90.0, F90.1, F90.2, F90.8, and F90.9. Psychosocial therapy was defined as having at least 1 relevant Current Procedural Terminology code in a claim within the year. A generalized linear model with a logit link and binomial distribution was used to assess factors associated with receipt of psychosocial treatment in 2016. RESULTS: More than 2500 (1.24%) preschool-aged children receiving Medicaid had a diagnosis of ADHD in 2016, with 988 (38.2%) of those receiving a stimulant medication. Children in foster care were diagnosed with and/or treated for ADHD 4 times more often than other Medicaid recipients. Of the 1091 preschoolers receiving stimulants, 99 (9%) did not have a diagnosis of ADHD. There were no significant differences in diagnoses by race/ethnicity, but children reported to be black, Hispanic, or other race/ethnicity received stimulants at a lower rate than white children. Positive predictors for receiving psychosocial therapy in 2016 included having the diagnosis but not receiving a stimulant, having at least 1 prescription written by a psychiatrist, having comorbidities, and age. The use of stimulants in children aged <6 years declined from 0.9% in 2012 to 0.5% in 2016. CONCLUSIONS: Promising trends demonstrate a decreasing use of stimulants in preschoolers; however, continued vigilance is needed to promote the optimal use of psychosocial interventions.

Analysis of Patient Visits and Collections After Opening a Satellite Pediatric Emergency Department.

OBJECTIVE: Satellite pediatric emergency departments (PEDs) have emerged as a strategy to increase patient capacity. We sought to determine the impact on patient visits, physician fee collections, and value of emergency department (ED) time at the primary PED after opening a nearby satellite PED. We also illustrate the spatial distribution of patient demographics and overlapping catchment areas for the primary and satellite PEDs using geographical information system. METHODS: A structured, financial retrospective review was conducted. Aggregate patient demographic data and billing data were collected regarding physician fee charges, collections, and patient visits for both PEDs. All ED visits from January 2009 to December 2013 were analyzed. Geographical information system mapping using ArcGIS mapped ED patient visits. RESULTS: Patient visits at the primary PED were 53,050 in 2009 before the satellite PED opened. The primary PED visits increased after opening the satellite PED to 55,932 in 2013. The satellite PED visits increased to 21,590 in 2013. Collections per visit at the primary PED decreased from $105.13 per visit in 2011 to $86.91 per visit in 2013. Total collections at the satellite PED decreased per visit from $155.41 per visit in 2011 to $128.53 per visit in 2013. CONCLUSIONS: After opening a nearby satellite PED, patient visits at the primary PED did not substantially decrease, suggesting that there was a previously unrecognized demand for PED services. The collections per ED visit were greater at the satellite ED, likely due to a higher collection rate.

Psychotropic Polypharmacy Among Children and Youth Receiving Medicaid, 2012-2015.

BACKGROUND: The rates of mental health diagnoses in children have increased. Children in poverty have the highest rates. The use of psychotropic medication for children has been increasing, which is concerning because of the unknown long-term effects and the increased burden on the health care system. The state of Kentucky ranks among the highest in the United States for children with mental health problems, children living in poverty, and children receiving psychotropic medication. OBJECTIVE: To examine recent trends and determinants of interclass psychotropic polypharmacy (PP) use for children and youth receiving Medicaid to inform intervention development. METHODS: A retrospective cohort study was conducted using 2012-2015 Kentucky Medicaid claims for children aged 0-17 years, with continuous enrollment for ≥ 90 days with at least 1 behavioral health diagnosis (N = 237,393). Interclass PP was defined as the presence of at least 2 psychotropic medication prescription fills for at least 2 different classes of medication that, if taken as directed, would be used concurrently for at least 90 consecutive days (allowing for a single 15-day lag). The outcome variables were the presence of any interclass PP and the number of months a child received interclass PP. We conducted a descriptive analysis and developed 2 separate generalized linear regression models to test for associations between individual characteristics of children treated with psychotropic medication for ≥ 90 days (n = 75,639) and each outcome of interest. RESULTS: For the sample of children with at least 90 days of psychotropic medication treatment, 38% had at least 3 covered months of PP over the 4 years studied. Children in foster care received alpha agonists (116 vs. 69 per 1,000 children) or antidepressants (225 vs. 176 per 1,000) at a higher rate than other children receiving Medicaid but received stimulants at a lower rate (403 vs. 638 per 1,000). The primary 2-drug class combinations were stimulants with either alpha agonists or antidepressants. Children in foster care (OR = 1.7, 95% CI = 1.58, 1.84, P < 0.001), with a bipolar disorder (OR = 2.24, 95% CI = 2.10, 2.38, P < 0.001), mood disorder not otherwise specified (OR = 1.11, 95% CI = 1.04, 1.17, P < 0.001), or autism spectrum disorders (OR = 1.17, 95% CI = 1.08, 1.26, P < 0.001) had increased the odds of ever receiving PP. Black children had lower odds (OR = 0.72, 95% CI = 0.67, 0.77, P < 0.001) of ever receiving PP. Children aged 6-11 years (beta = 3.08, 95% CI = 2.87, 3.29) and 12-17 years (beta = 1.61, 95% CI = 1.38, 1.83) had more covered months with PP compared with those aged 0-5 years. Black children had fewer covered months of PP compared with white children (beta = -1.36, 95% CI = -1.61, -1.11]. Children in foster care (beta = 1.83, 95% CI = 1.53, 2.13) had more covered months with PP. Children residing in nonurban areas had fewer months with PP (beta = -0.4, 95% CI = -0.54, -0.26) compared with those residing in urban areas, as did those children with depression (beta = -3.32, 95% CI = -3.55, -3.1), impulse control disorder (beta = -2.07, 95% CI = -2.28, -1.85), and conduct disorder (beta = -1.34, 95% CI = -1.64, -1.05). Children with bipolar disorder (beta = 3.62, 95% CI = 3.38, 3.86) and autism (beta = 2.04, 95% CI = 1.75, 2.33) had more covered months with PP. As comorbidity increased, the duration of PP treatment increased (beta = 2.49, 95% CI = 2.36, 2.62). CONCLUSIONS: The rates of PP are concerning, especially for children in foster care and children aged 6-11 years. Efforts to safeguard medication use are needed, as well as future exploration of racial differences in PP.

Unintentional, non-fatal drowning of children: US trends and racial/ethnic disparities.

OBJECTIVE: The current study aimed to better understand trends and risk factors associated with non-fatal drowning of infants and children in the USA using two large, national databases. METHODS: A secondary data analysis was conducted using the National Inpatient Sample and the Nationwide Emergency Department Sample databases. The analytic sample (n=19,403) included children <21 years of age who had a diagnosis code for near-drowning/non-fatal drowning. Descriptive, χ(2) and analysis of variance techniques were applied, and incidence rates were calculated per 100,000 population. RESULTS: Non-fatal drowning incidence has remained relatively stable from 2006 to 2011. In general, the highest rates of non-fatal drowning occurred in swimming pools and in children from racial/ethnic minorities. However, when compared with non-Hispanic Caucasian children, children from racial/ethnic minorities were more likely to drown in natural waterways than in swimming pools. Despite the overall lower rate of non-fatal drowning among non-Hispanic Caucasian children, the highest rate of all non-fatal drowning was for non-Hispanic Caucasian children aged 0-4 years in swimming pools. Children who were admitted to inpatient facilities were younger, male and came from families with lower incomes. CONCLUSIONS: Data from two large US national databases show lack of progress in preventing and reducing non-fatal drowning admissions from 2006 to 2011. Discrepancies are seen in the location of drowning events and demographic characteristics. New policies and interventions are needed, and tailoring approaches by age and race/ethnicity may improve their effectiveness.
