Introduction. Frontline COVID-19 healthcare workers (FLHCWs) are at a high-risk of suffering occupational stress- and trauma-related mental health problems, including burnout and compassion fatigue (B&CF). Given the time limitations (due to their heavy workloads) and need to minimize face-to-face interventions (in order to avoid contagions), psychological interventions for FHCWs should be as brief and remote as possible. Objective. To evaluate the usability and clarity of evidence-based psycho-educational videos to prevent B&CF, to deal with uncooperative, hostile, and anxious patients and relatives, and to use personal protective equipment (PPE), from the perspective of Mexican FLHCWs. Method. Based on a convenience sampling by intensity approach, videos were distributed requesting feedback based on specific questions through WhatsApp to FLHCWs. Field notes were used to triangulate the information. Results. Content analysis of feedback from a final sample of 24 participants ‒75% women, 42 ± 8.4 years old‒ yielded three general thematic categories and seven subthemes: 1. content evaluation, which included three subthemes: utility, pertinence, and practicality; 2. dissemination and other needs, with two subcategories: willingness to share and receive more videos (other needs); and 3. format aspects, also comprising two subthemes: attractiveness and duration. All participants found the videos content very beneficial, relevant, and applicable to the workplace and even in their everyday personal and family life, and were willing to share them and to receive more videos on other issues, including strategies to manage problems related to isolation. Discussion and conclusion. Escalation of this remote preventive intervention to other COVID-19 centers and future similar epidemics is recommended.
