Detaljert beskrivelse
Frontline healthcare workers, first responders, and emergency medical personnel are repeatedly exposed to occupational stressors and potentially traumatic events, placing them at elevated risk for post-traumatic stress symptoms (PTSS), burnout, anxiety, and related impairments. Current stress-reduction approaches for healthcare workers often have limited evidence for efficacy or may be difficult to implement in high-demand emergency and healthcare settings. Therefore, rapid, low-burden interventions that are feasible, tolerable, and safe for this population are needed.
Floatation-REST, or Reduced Environmental Stimulation Therapy, is a non-pharmacological intervention that reduces sensory input to the nervous system through the act of floating supine in a pool of warm water saturated with Epsom salt. The float environment is designed to reduce visual, auditory, thermal, tactile, vestibular, and proprioceptive stimulation. Prior studies suggest that Floatation-REST may acutely reduce stress and anxiety-related symptoms, but it has not yet been systematically evaluated in frontline healthcare workers with elevated PTSS.
This single-site, double-arm pilot study will examine the feasibility, tolerability, and safety of two 60-minute sessions of Floatation-REST compared with a documentary-viewing condition in adults ages 18 to 64 with work-related post-traumatic stress symptoms. Up to 30 participants will be recruited, with the goal of retaining 15 completers randomized on a 2:1 basis to Floatation-REST versus comparator condition. Participants will complete two in-person study visits at the Laureate Institute for Brain Research, including self-report questionnaires, blood and saliva collection, functional magnetic resonance imaging scans, and either Floatation-REST or documentary viewing. Follow-up surveys will be completed virtually up to one week after final intervention session.
The primary aim is to evaluate the safety and tolerability of Floatation-REST in this population. Secondary aims will explore whether Floatation-REST is associated with acute changes in PTSS, perceived stress, anxiety, burnout, mood, mindfulness, and moral injury-related distress. Exploratory aims will examine whether changes in brain network connectivity, salivary cortisol, and blood-based proteomic markers may help explain symptom change. Results from this early-stage study will help determine whether Floatation-REST should be further studied as a potential intervention for post-traumatic stress symptoms in frontline healthcare and emergency personnel.

Adverse effects
Tidsramme: From baseline to post-intervention seven day follow-up
|
Safety will be assessed using adverse events reported directly to study staff and adverse effects reported on the Floatation-REST effects checklist after each Floatation-REST or comparator session.
As a proxy of safety, adverse effects will be calculated for each participant as the number of instances during the study in which the participant reports an increase above mild for any negatively experienced effect on the checklist.

Dropout Rate
Tidsramme: Baseline through seven day post-intervention follow up
|
As a proxy for tolerability, dropout rate for each arm = (# of subjects who are withdrawn from the study)/(# participants in specific arm).
