Utilisation and costs of mental health-related service use among adolescents.

ABSTRACT

BACKGROUND: The high level of care needs for adolescents with mental health conditions represents a challenge to the public sector, especially in low and middle-income countries. We estimated the costs to the public purse of health, education, criminal justice and social care service use associated with psychiatric conditions among adolescents in Brazil; and examined whether the trajectory of psychopathology and its impact on daily life, and parental stigma towards mental illness, was associated with service utilisation and costs. METHODS: Data on reported service use among adolescents from a prospective community cohort (n = 1,400) were combined with Brazilian unit costs. Logistic regression and generalised linear models were used to examine factors associated with service use and associated costs, respectively. RESULTS: Twenty-two percent of those who presented with a psychiatric disorder used some type of service for their mental health in the previous twelve months. Higher odds of service use were associated with having a diagnosed mental disorder (either incident, [OR = 2.49, 95%CI = 1.44-4.30, p = 0.001], remittent [OR = 2.16, 95%CI = 1.27-3.69, p = 0.005] or persistent [OR = 3.01, 95%CI = 1.69-5.36, p<0.001]), higher impact of symptoms on adolescent's life (OR = 1.32, 95%CI = 1.19-1.47, p<0.001) and lower parental stigma toward mental illness (OR = 1.12, 95%CI = 1.05-1.20, p = 0.001). Average annual cost of service use was 527.14 USD (s.d. = 908.10). Higher cost was associated with higher disorder impact (ß = 0.25, 95%CI = 0.12-0.39, p<0.001), lower parental stigma (ß = 0.12, 95%CI = 0.02-0.23, p = 0.020) and white ethnicity (ß = 0.55, 95%CI = 0.04-1.07, p = 0.036). CONCLUSION: The impact of mental health problems on adolescents' daily lives and parental stigmatising attitudes toward mental illness were the main predictors of both service use and costs.
