Overview

Economic evaluation reveals early intervention for psychosis likely cost-effective in Chile, suggesting good value for resources.

Key Points

  • To estimate the cost-effectiveness of early intervention for psychosis services in Chile compared to community mental health teams.
  • Developed a six-state Markov model for cost-effectiveness analysis
  • Compared early intervention for psychosis services against community mental health teams
  • Used data from a Chilean EIP cohort and published literature
  • Conducted probabilistic sensitivity analysis
  • Calculated value of information to analyze uncertainty in outcomes.
  • EIP was found to be cost-effective with an ICER of 5,550,044 Chilean pesos per QALY
  • 80% probability of EIP services being the most cost-effective option at a willingness-to-pay threshold of USD 15,923
  • Results sensitive to intervention effectiveness and cost, indicating need for further trials
