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 identi- fying 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 involving 110 cardiorespiratory failure survivors.
Our specific aims will: (1) Optimize the usability of a self-directed mobile app (mCST) and an automated post-discharge distress screening system; (2) Test two promising iterations of mCST vs. usual care in a pilot 3-arm RCT with 3- month follow up, and (3) Explore facilitators and barriers to mCST implementation, using these data to inform any necessary final revisions to the mCST app. Our team has the proven expertise to conduct this R34, which is both necessary and sufficient to inform a next-step efficacy-focused multicenter RCT that could advance the field with a personalizable yet scalable therapy. Innovations include mCST?s paradigm-shifting approach to automated screening, therapy, and outcomes assessment. Overall, mCST could significantly improve access to psychosocial therapies and augment any hospital- or clinic-based intervention. Last, this R34 addresses current research priorities outlined by the NIH, the National Academy of Medicine, and professional societies.
STATEMENT Millions of patients experience cardiorespiratory failure requiring treatment in an intensive care Unit (ICU) each year. Less commonly appreciated is the fact that afterward, they commonly suffer from serious symptoms of depression, anxiety, and post-traumatic stress disorder (PTSD)?often for years. Because patients have few therapies relevant to their experience, we proposal testing an innovative self-directed app-based coping skills training program to see how well it reduces symptoms among patients with high levels of distress after arriving home from the hospital.
