mobile coping skills training to improve cardiorespiratory failure survivors' psychological distress

Conditions: Cardiorespiratory Failure

Summary: this is a pilot randomized clinical trial involving adult survivors of cardiorespiratory failure treated in intensive care units (icus) that is designed to test the acceptability, feasibility, and clinical impact of a coping skills training intervention (blueprint) delivered via a mobile app. this trial will allow us to determine if new changes to intervention delivery, inclusion criteria, and other factors are successful. it will also inform the development of a next-step efficacy focused trial.

as survival has improved for the 2 million people with cardiorespiratory failure managed annually in us intensive care units (icus), research has clarified how these survivors suffer from severe and persistent symptoms of psychological distress-depression, anxiety, and post-traumatic stress disorder (ptsd)-after discharge. however, few interventions exist that are relevant to patients' experiences and that also accommodate their many physical, social, and financial barriers to personalized care. to fill this gap, we developed a telephone- and web-based coping skills training (cst) program. cst is an empirically-supported psychosocial intervention that targets the use of the adaptive coping skills to decrease psychological distress and improve quality of life. we conducted a multicenter randomized clinical trial (rct) called cstep that compared cst to an education program (ep) among a general sample of icu survivors who received mechanical ventilation for cardiorespiratory failure. cst reduced depression symptoms and improved quality of life at 6 months in a pre-specified subgroup with elevated baseline distress. this rct also identified key questions regarding best practices for identifying patients who are highly distressed yet whose physical illness is manageable, as well as delivering the intervention in a more convenient, and scalable manner. in a recent rct testing a mindfulness intervention (lift), we found that a self-directed mobile app approach increased dose, adherence, and retention. however, many patients reported low enthusiasm for a meditation-based intervention. what is needed before a second multicenter rct is to apply the promising cst content to a lift-inspired mobile app-based delivery system, and then to test it within a targeted patient population with a high likelihood of response (i.e., high baseline psychological distress). therefore, we propose a 2-year r34 mixed-methods project that includes a pilot rct in which we will randomize 45 cardiorespiratory failure / insufficiency survivors to one of three arms in equal ratios: intervention plus therapist for non-responders (n \~15), intervention without a therapist (n \~15), and usual care control (n \~15). randomization will be stratified by icu service (medical vs. surgical), baseline hads score (\<14 vs. ≥14), and age (\<50 vs. ≥50). our specific aims will: (1) optimize the usability of a self-directed mobile app (blueprint) and an automated post-discharge distress screening system; (2) test two promising iterations of blueprint vs. usual care in a pilot 3-arm rct with 3-month follow up, and (3) explore facilitators and barriers to blueprint implementation, using these data to inform any necessary final revisions to the blueprint app.
