Clinical Pearls
4 pearls-
Do not stop treatment planning at the end of the 4-week esketamine index course; acute benefit was modest, with a mean MADRS change of −14.1 points (SD = 11.1), a response rate of 26.5%, and a remission rate of 10.8% at week 5.
-
If you are tracking suicidal ideation after esketamine, use more than the C-SSRS ideation subscale; CBT separated from TAU on BSSI at week 18 (−6.01 vs −4.10; mean difference of −1.91, 95% CI, −3.57 to −0.24, P=.025) but not on the C-SSRS (−0.80 vs −0.93; group difference 0.13, 95% CI −0.39 to 0.65, P=.623).
-
A structured 16-week CBT course is deliverable even in patients with MDSI during and after esketamine treatment; 72/93 (77.4%) were retained through week 18, CBT session completion was 80.7%, and completion of the 9 computer-assisted modules was 76.7%.
-
When designing or interpreting suicide-focused trials, remember that risk clusters in hospitalized patients; 14/19 suicide-related events occurred in those hospitalized at enrollment, and the authors estimate that detecting a moderate treatment effect would require 200–300 participants from hospitals or similar settings.
