Psychotherapy Claims Surrounding Pharmacotherapy Initiation in Children and Adolescents with Anxiety Disorders

Patterns of mental health service use among Medicaid-insured youths treated by nurse practitioners and physicians: A retrospective cohort study

BACKGROUND

Despite the growing involvement of nurse practitioners in mental health services for children and adolescents, little is known about the patterns of mental health service use among youths treated by nurse practitioners compared to those by physicians.

OBJECTIVES

To identify new users of psychotropic medications initiated by nurse practitioners and physicians among Medicaid-insured youths and to assess if receiving psychosocial services prior to or concurrent with medication initiation differs among youths treated by provider and specialty type.

DESIGN

A retrospective cohort study.

SETTINGS

We used Medicaid-insurance claims data in one mid-Atlantic state in the US.

PARTICIPANTS

A total 12,991 Medicaid-insured youths aged 0-20 years who started psychotropic medications prescribed by nurse practitioners or physicians with primary care or psychiatric specialty during 2013-2014.

METHODS

Providers were grouped into nurse practitioners and physicians and into primary care and psychiatric specialty. Descriptive statistics were performed to compare each class of psychotropic medications initiated and psychiatric diagnoses of enrollees according to provider type within each specialty. Using multinomial logistic regression with psychiatrists as a reference group, we estimated the odds of having a type of prescriber for psychotropic medication initiation for youths who received psychosocial services prior to a new start of the medication and concurrently, compared to that for those who did not, after adjusting for patients' demographic characteristics and diagnosis.

RESULTS

Youths served by nurse practitioners resided in small and non-metropolitan areas significantly more often than those served by their physician counterparts. There was no major difference in a class of psychotropic medications initiated by nurse practitioners and physicians within each specialty type, except a higher proportion of antidepressants (13.5% versus 10.5%) and a lower proportion of attention deficit hyperactivity disorder medications prescribed (68.8% versus 74.0%) by primary care nurse practitioners compared to their physician counterparts. Youths who received psychosocial services prior to medication initiation were less likely to have primary care physicians (Adjusted odds ratio=0.15, 95% confidence interval=0.82, 1.33) or primary care nurse practitioners (Adjusted odds ratio=0.16, 95% confidence interval=0.12, 0.20) as their initiating prescriber than those who did not.

CONCLUSIONS

Youths treated by nurse practitioners and physicians with or without psychiatric specialty showed unique patterns of mental health service use. Our findings can be used to build effective collaborations among provider and specialty type for quality of mental health services delivered to targeted populations in need.

Novel pharmacological treatments for generalized anxiety disorder: Pediatric considerations

BACKGROUND

Pediatric anxiety disorders such as generalized anxiety disorder (GAD) are common, impairing, and often undertreated. Moreover, many youth do not respond to standard, evidence-based psychosocial or psychopharmacologic treatment. An increased understanding of the gamma-aminobutyric acid (GABA) and glutamate neurotransmitter systems has created opportunities for novel intervention development for pediatric GAD.

METHODS

This narrative review examines potential candidates for pediatric GAD: eszopiclone, riluzole, eglumegad (LY354740), pimavanserin, agomelatine.

RESULTS

The pharmacology, preclinical data, clinical trial findings and known side effects of eszopiclone, riluzole, eglumegad (LY354740), pimavanserin, agomelatine, are reviewed, particularly with regard to their potential therapeutic relevance to pediatric GAD.

CONCLUSION

Notwithstanding numerous challenges, some of these agents represent potential candidate drugs for pediatric GAD. Further treatment development studies of agomelatine, eszopiclone, pimavanserin and riluzole for pediatric GAD also have the prospect of informing the understanding of GABAergic and glutamatergic function across development.

Provider-Level Caseload of Psychosocial Services for Medicaid-Insured Children

OBJECTIVE

We estimated the caseload of providers, practices, and clinics for psychosocial services (including psychotherapy) to Medicaid-insured children to improve the understanding of the current supply of such services and to inform opportunities to increase their accessibility.

METHODS

We used 2012-2013 Medicaid claims data and data from the 2013 National Plan and Provider Enumeration System to identify and locate therapists, psychiatrists, and mental health centers along with primary, rehabilitative, and developmental care providers in the United States who provided psychosocial services to Medicaid-insured children. We estimated the per-provider, per-location, and state-level caseloads of providers offering these services to Medicaid-insured children in 34 states with sufficiently complete data to perform this analysis, by using the most recent year of Medicaid claims data available for each state. We measured caseload by calculating the number of psychosocial visits delivered by each provider in the selected year. We compared caseloads across states, urbanicity, provider specialty (eg, psychiatry, psychology, primary care), and practice setting (eg, mental health center, single practitioner).

RESULTS

We identified 63 314 providers, practices, or centers in the Medicaid claims data that provided psychosocial services to Medicaid-insured children in either 2012 or 2013. The median provider-level per-year caseload was <25 children and <250 visits across all provider types. Providers with a mental health center-related taxonomy accounted for >40% of visits for >30% of patients. Fewer than 10% of providers and locations accounted for >50% of patients and visits.

CONCLUSIONS

Psychosocial services are concentrated in a few locations, thereby reducing geographic accessibility of providers. Providers should be incentivized to offer care in more locations and to accept more Medicaid-insured patients.
