Insights

The Baby Steps Wellbeing online program is a cost-effective intervention for parents, showing slightly improved health outcomes and cost savings compared to a basic information program.

Area of Science:

  • Mental Health
  • Digital Health Interventions
  • Health Economics

Background:

  • Internet-based parental programs can enhance parental wellbeing and reduce mental health burdens during the perinatal period.
  • Limited research exists on the cost and clinical impacts of such digital interventions.
  • This study evaluates the cost-effectiveness of an online cognitive behaviour therapy (CBT) program for parents.

Purpose of the Study:

  • To assess the cost-effectiveness of the Baby Steps Wellbeing online CBT intervention compared to an information-only program (Baby Care).
  • To analyze direct healthcare costs and indirect costs from income loss.
  • To determine the impact on quality-adjusted life years (QALYs) from a societal perspective.

Main Methods:

  • A randomized clinical trial with alongside-trial cost-effectiveness analysis.
  • Inclusion of direct healthcare and indirect income loss costs.
  • Utilized the Assessment of Quality of Life-8 Dimensions for utility measures and calculated QALYs.
  • Employed incremental cost-effectiveness ratios (ICERs) and a societal perspective.

Main Results:

  • 496 parents were randomized; no significant differences in costs (-$27) or QALYs (0.051) were found between groups.
  • Bootstrapped analysis indicated the Baby Steps Wellbeing program was cost-saving and health-improving in 38% of simulations.
  • The program was found to be cost-effective in an additional 37% of simulations.

Conclusions:

  • The Baby Steps Wellbeing program demonstrated slight cost savings and improved health outcomes compared to the Baby Care control.
  • Bootstrapped results suggest the Baby Steps Wellbeing program is cost-effective in 75% of simulations.
  • The online Baby Steps Wellbeing program is concluded to be a cost-effective intervention for parental mental health.
