Brief Summary

Psychological and existential distress are a common cause of suffering among patients nearing the end of life, and a major reason for requesting medical aid in dying. Existing treatments for psychological and existential suffering have low efficacy and are challenging to use in a palliative context. There is a need to develop scalable, brief, and rapidly effective therapeutic approaches that can reduce psychological and existential distress in patients nearing the end of life. Repetitive Transcranial Magnetic Stimulation is an effective treatment for refractory depression, and new protocols and increasing availability of rTMS may make this therapy feasible and acceptable for patients who suffer from psychological or existential distress near the end of life. Among patients with advanced illness followed by a PC provider, the study objectives are to:

  1. 1.Identify the lowest and range of therapeutic rTMS dose to relieve psychological distress, including an analysis of clinical predictors of response.
  2. 2.Test the feasibility and preliminary efficacy of rTMS for the treatment of psychological distress including: 1) ease of recruitment; 2) completion of follow-up; 3) effect size and variance estimates of treatment for primary and secondary outcomes; and 4) patient satisfaction with treatment.

Outcome Measures

Primary Outcomes (7)

  • Change in Psychological Distress, Depression

    17-Item Hamilton Rating Scale for Depression (HRSD); scores 0-52; higher score is more severe depression

    Baseline (1 day prior to treatment start); after each day of rTMS treatment; 2 weeks, 4, and 8 weeks after intervention completion, if participant is alive

  • Change in Psychological Distress, Depression and Anxiety

    The Hospital Anxiety and Depression Scale (HADS); scores 0-21; higher score is more severe anxiety/depression

    Baseline (1 day prior to treatment start); after each day of rTMS treatment; 2 weeks, 4, and 8 weeks after intervention completion, if participant is alive

  • Recruitment Rate

    Total number of participants divided by the total number of eligible patients approached

    Measured upon study enrollment termination (estimated at 8 months for dose-finding study)

  • Recruitment Rate

    Total number of participants divided by the total number of eligible patients approached

    Measured upon study enrollment termination (estimated at 12 months for feasibility randomized clinical trial)

  • Completion of Intervention

Study Arms (1)

rTMS Intervention Group

EXPERIMENTAL
Device: repetitive Transcranial Magnetic Stimulation (rTMS)

Interventions

The rTMS intervention will be performed in a dedicated rTMS patient room on the PC unit, where the patient can remain in their bed seated upwards at a 45 degree angle, or seated in a chair. The stimulation intensity for treatment will be determined by measuring the resting and active motor threshold (rMT and aMT) using single pulse TMS over the motor cortex using standard techniques as in previous trials. Investigators will use left-sided intermittent theta burst stimulation (iTBS). The trained team member will locate the left DLPFC using the BeamF3 technique. For the open-label dose-finding study, this region will be stimulated intermittently at 3 TMS pulses every 200 milliseconds for 2 seconds (i.e. 30 stimulations). This procedure is repeated every 10 seconds for a total duration of 3 minutes during which 600 total pulses are delivered. Participants will receive up to 8 3-minute sessions daily at 45 minute intervals for 5 days (consecutively or in a seven-day window if need be).
