The weighted mean difference in cost savings vs. TAU derived after the provision of DBT vs. non-DBT studies was: $1,228.43 (SE = $251.13; 95% confidence interval $735.63 to $1,721.30). This resulted in a significant weigthed mean difference (t(953.33.) = 4.892, p = .000). Although the difference per patient is significant, it is important to recognise that treatments themselves begin from different cost bases–and DBT standard includes weekly 2.5 hours of group, one hour of individual and ancillary care and phone coaching–which is generally more intensive that the comparative treatments which are typically up to two hours individual per week. In addition, crisis care, because it diverts from hospitalisation, has a large cost-offset. Although there are many potential interpretations for this significant finding, it could suggest that there is a greater cost-benefit of non-DBT vs DBT approaches compared to TAU. However, caution should be used when interpreting these results.
