Cost-effectiveness analysis of screening three-year old for social-emotional problems

Abstract Aim To assesses the long-term cost-effectiveness of a population-based screening to detect social-emotional problems at 3-years-old combined with an evidence-based intervention to prevent mental health problems. Methods A decision-analytic Markov model compares two alternatives 1) all 3-years-old get screened for social-emotional problems, and parents for children at a high risk receive a generic targeting parenting intervention 2) no screening and no intervention. The cohort of 3-year-old is modeled until they are 19 years old. The screening test is the ASQ:SE and the intervention was given to children with scores that suggest social-emotional problems. The model considered development of anxiety, conduct problems, and ADHD, over the 16 years. The analyses were done from a societal and healthcare perspectives. Health outcomes were assessed with DALYs averted. Results Results suggest that the probability of population-based screening for social-emotional problems combined with the parenting intervention to high risk-children being cost-effective is high, adopting a societal and healthcare perspective, 98% and 97% each. From a societal perspective, the likelihood of cost saving is high, 85 %. The combination of screening and intervention strongly dominated the comparator. Conclusions The findings align with previous research; prevention aimed at children’s mental health disorders will likely yield high investment returns. Successful implementation of population-based screening for social-emotional problems combined with an effective evidence-based parenting intervention might be an important way to contribute to sustainable and efficient mental health care. Key messages • The impact of combining population-based screening with intervention is encouraging when considering a long-term view. • Prevention aimed at children’s mental health will likely yield high investment return.
