Abstract
OBJECTIVE: Posttraumatic stress disorder (PTSD) symptoms (PTSS) are common after minor injuries and can impair recovery. We sought to understand whether an evidence-based mobile phone application with self-help tools (PTSD Coach) could be useful to improve recovery after acute trauma among injured emergency department (ED) patients. This pilot study examined the feasibility, acceptability, and potential benefit of using PTSD Coach among acutely injured motor vehicle crash (MVC) patients. METHODS: From September 2017 to September 2018, we recruited adult patients within 24 hours post-MVC from the EDs of two Level I trauma centers in the United States. We randomly assigned 64 injured adults to either the PTSD Coach (n = 33) or treatment as usual (TAU; n = 31) condition. We assessed PTSS and associated symptoms at 1 month (83% retained) and 3 months (73% retained) postenrollment. RESULTS: Enrollment was feasible (74% of eligible subjects participated) but usability and engagement were low (67% used PTSD Coach at least once, primarily in week 1); 76% of those who used it rated the app as moderately to extremely helpful. No differences emerged between groups in PTSS outcomes. Exploratory analyses among black subjects (n = 21) indicated that those in the PTSD Coach condition (vs. TAU) reported marginally lower PTSS (95% CI = -0.30 to 37.77) and higher PTSS coping self-efficacy (95% CI = -58.20 to -3.61) at 3 months. CONCLUSIONS: We demonstrated feasibility to recruit acutely injured ED patients into an app-based intervention study, yet mixed evidence emerged for the usability and benefit of PTSD Coach. Most patients used the app once and rated it favorably in regard to satisfaction with and helpfulness, but longitudinal engagement was low. This latter finding may explain the lack of overall effects on PTSS. Additional research is warranted regarding whether targeting more symptomatic patients and the addition of engagement and support features can improve efficacy.
