Patterns of Mental Health Service Use During the Transition to Adulthood Among Autistic Adolescents and Young Adults

Community brief Why is this an important issue?Autistic adolescents and young adults often do not receive the mental health care services they need. As they transition into adulthood, they may lose important mental health services they relied on during childhood. Losing services may negatively affect their health and produce bad outcomes such as emergency department visits. Previous studies have suggested that autistic individuals often stop receiving important services as they leave school and lose access to school-based services. What was the purpose of this study?The purpose was to describe patterns of mental health service use during the transition to adulthood among autistic adolescents and young adults. Underutilized services might indicate areas where the health care system needs to improve. What did the researchers do?We used data from electronic health records from a large university health system in the southeastern United States. We identified autistic adolescents and young adults ages 11-27 in the data. We analyzed whether they received medication and/or psychotherapy for their mental health, and whether they had emergency department visits and adverse drug events. We also examined polypharmacy, meaning the use of multiple medications of different classes for mental health. What were the results of the study?Almost half of the 529 included patients experienced polypharmacy. The majority received medication only, whereas smaller percentages received medication plus psychotherapy or psychotherapy alone. Emergency department visits were most common in the 17-21 age group, and psychotropic medications and polypharmacy were most used in the 22-27 age group. Black individuals were more likely to receive psychotherapy and less likely to receive psychotropic polypharmacy than non-Hispanic Whites. What do these findings add to what was already known?These findings show that providers are relying heavily on medication, often including polypharmacy, to treat mental health issues in autistic adolescents and young adults. What are potential weaknesses of the study?The study used only one health care system in one state and may not reflect what happens in other states with different policies. Data may include a high number of patients with complex medical conditions, which may not reflect the typical patient's experience. Medications prescribed by providers outside this particular health system may not be captured. How will these findings help autistic adults now or in the future?These findings reveal potential areas for improvement for providers and health systems in treating autistic adults. Ensuring that autistic adolescents can continue to receive important mental health services as they age into adulthood can improve their health. Background: The time of transition into adulthood, especially when leaving school, is a time when many autistic adolescents and young adults (AYA) may stop receiving mental health services that they have relied on, leading to worse mental health outcomes. The purpose of this study was to describe patterns of mental health service use during transition to adulthood among autistic AYAs.Methods: We performed a cross-sectional study using electronic health records from years 2015 to 2019 from one large university health care system. We included autistic individuals ages 11-27 with at least one clinical encounter annually in the cohort. Outcomes included psychotropic medications and psychotherapy received, psychotropic polypharmacy, psychiatric emergency department (ED) visits, and adverse drug events.Results: Almost half of the 529 patients in the cohort received polypharmacy. The most common treatment was medication only (56.9%), followed by no treatment (22.7%), medication plus psychotherapy (18.7%), and psychotherapy only (data masked). The 17-21 age group had the highest odds of a psychiatric ED visit, whereas the 22-27 age group had the highest odds of receiving psychotropic medications and polypharmacy. Black AYA were more likely to receive psychotherapy and less likely to receive psychotropic polypharmacy than non-Hispanic Whites.Conclusion: Autistic individuals may benefit from more support from the health care system for their transition into adulthood to maintain use of beneficial mental health services as they leave school and to reduce the frequency of adverse outcomes. Access to providers experienced treating the complex needs of autistic individuals is important to reduce disparities.
