Program

In-person AND virtual! – We are pioneering a new conference format that will connect in-person and virtual audiences to create a unique experience. Matching the innovation that comes through our members’ work, ISPOR is pushing the boundaries of innovation to design an event that works in today’s quickly changing environment. 

In-person registration included the full virtual experience, and virtual-only attendees will be able to tune into live in-person sessions and/or watch captured in-person sessions on-demand in addition to having a variety of virtual-only sessions to attend.

Objectives: To examine cost-effectiveness for payers, with respect to quality-adjusted life years (QALYs), of a digital wellness intervention (DWI) for managing depression and anxiety relative to psychoeducation.

Methods: A Markov model of 10,000 hypothetical individuals was created to estimate costs (2019 USD) and QALYs for a DWI (Happify Health) vs. psychoeducation. Four depression-related health states (none, mild, moderate, severe) were used, with a subdistribution of anxiety levels (none, mild/moderate, severe) within each state. Efficacy data from a RCT that compared a DWI to psychoeducation in people with moderate to severe depression (PHQ>9) was used. Direct treatment costs were estimated from the Kantar 2019 National Health and Wellness Survey (NHWS) for each depression and concurrent anxiety level. Health utility estimates based on NHWS Short Form (SF)-6D responses for corresponding health states were converted into QALYs. Individuals were cycled through each intervention over six months, with cycle lengths of two months. Incremental cost-effectiveness ratios (ICER) and net monetary benefit (NMB) were determined at a willingness-to-pay threshold of $150,000. One-way sensitivity analysis (SA) examined individual parameter uncertainty. Two-way SA explored the impact of varying intervention costs. Deterministic SA was used to examine the impact of dropout rates. Data were analyzed in TreeAge Pro 2021 (TreeAge Software, Williamstown, MA).

Results: The DWI and psychoeducation incurred mean costs of $3604 and $3602 and mean QALYs of 0.852 and 0.849, respectively. The ICER was $7543 per QALY gained. The most sensitive parameters were the cost of the DWI and the probabilities of moving from moderate to severe and from severe to mild depression. The DWI was cost-effective when costs were $100-$230. NMB was favorable for the DWI in 46% of simulations.

Conclusion: With respect to QALYs, the DWI was cost-effective vs. psychoeducation and its introduction at a population level could benefit payers.
