The transition from Child and Adolescent Mental Health Services (CAMHS) to Adult Mental Health Services (AMHS) can be challenging for youth, their families, and healthcare providers. The purpose of this study was to identify, summarize, and assess evidence found in scholarly literature regarding the economic impact on youth and their families during the transition from CAMHS to AMHS. Relevant studies were identified through a search of 7 electronic platforms. The search identified 829 articles; 5 of which met all inclusion criteria. Evidence from the included studies suggests that, when continuity of care is lacking, transitions from CAMHS to AMHS have substantial impacts on the financial demands of youth and their families. These demands are due to increases in the cost of care, loss of employment income and productivity, and changes in insurance coverage. However, there remains limited information in this area, which highlights the need for further research.
