Feasibility of Mobile App-based Coping Skills Training for Cardiorespiratory Failure Survivors: The Blueprint Pilot Randomized Controlled Trial.

Psychological distress symptoms are common among patients recently hospitalized with cardiorespiratory failure, yet there are few effective postdischarge therapies that are relevant to their experiences. To determine the feasibility and clinical impact of two different versions of a month-long self-guided mobile app-based coping skills program called Blueprint in comparison to usual care (UC) control. Patients hospitalized with a serious cardiopulmonary diagnoses were recruited from adult intensive care units and stepdown units at a large academic medical center. Participants with elevated psychological distress symptoms just after discharge were randomized in a 1:1:1 ratio to Blueprint with a therapist (BP/therapist), Blueprint without a therapist (BP/no therapist), or UC control. All study procedures were conducted remotely. Blueprint is a self-guided, symptom-responsive, mobile app-based adaptive coping skills program with 4 themed weeks with different daily audio, video, and text content. Participants completed surveys via the app platform at baseline and 1 and 3 months later. The primary outcome was feasibility. Additional outcomes included the HADS (Hospital Anxiety and Depression Scale) total score, the PTSS (Post-Traumatic Stress Scale), and a 100-point quality of life visual analog scale. Of 63 patients who consented, 45 (71%) with elevated distress were randomized to BP/therapist ( = 16 [36%]), BP/no therapist ( = 14 [31%]), and UC ( = 15 [33%]). Observed rates were similar to target feasibility benchmarks, including consented patients who were randomized (71.4%), retention (75.6%), and intervention adherence (97% with weekly use). Estimated mean differences (95% confidence intervals) at 1 month compared with baseline included: HADS total (BP/therapist, -3.8 [-6.7 to -0.6]; BP/no therapist, -4.2 [-7.6 to -0.0]; UC, -3.4 [-6.6 to 0.2]); PTSS (BP/therapist, -6.7 [-11.3 to -2.1]; BP/no therapist, -9.1 [-14.4 to -3.9]; UC, -4.2 [-10.8 to 2.3]); and quality of life (BP/therapist, -4.5 [-14.3 to 4.6]; BP/no therapist, 14.0 [-0.9 to 29.0]; UC, 8.7 [-3.5 to 20.9]). Among survivors of cardiorespiratory failure, a mobile app-based postdischarge coping skills training intervention demonstrated evidence of feasibility and clinical impact compared with UC control. A larger trial is warranted to test the efficacy of this approach. Clinical trial registered with ClinicalTrials.gov (NCT04329702).
