How patient preferences relate to outcomes in a study comparing electroconvulsive therapy and ketamine for hard-to-treat depression

Updated

Abstract

Ketamine was preferred by more trial participants than ECT.

  • Preference for ketamine was linked to a higher likelihood of treatment response for all patients, regardless of their assigned treatment.
  • Receiving the preferred treatment (preference-matching) increased the likelihood of treatment response specifically for ketamine.
  • Preference-matching was associated with fewer adverse events in patients treated with ECT.
  • There was a trend suggesting that preference-matching could influence treatment adherence.
