IntroductionSince the emergence of the novel coronavirus disease (COVID-19), the world has faced a pandemic with consequences at all levels. In many countries, the health systems collapsed and healthcare professionals had to be on the front line of this crisis. The adverse effects on the mental health of healthcare professionals have been widely reported. This research focuses on identifying the main factors associated with adverse psychological outcomes. MethodsDescriptive, cross-sectional study based on surveys, applying the PHQ-9, GAD-7, ISI and EIE-R tests to healthcare professionals from Ecuador during the COVID-19 pandemic. Results1028 participants, distributed in: 557 physicians (54.18%), 349 nurses (33.94%), 29 laboratory workers (2.82%), 27 paramedics (2.62%), 52 psychologists (5.05%) and 14 respiratory therapists (1.36%), from 16 of the 24 provinces of Ecuador. Of these, 27.3% presented symptoms of depression, 39.2% anxiety symptoms, 16.3% insomnia and 43.8% symptoms of PTSD, with the 4 types of symptoms ranging from moderate to severe. The most relevant associated factors were: working in Guayas (the most affected province) (OR = 2.18 for depressive symptoms and OR = 2.59 for PTSD symptoms); being a postgraduate doctor (OR = 1.52 for depressive symptoms and OR = 1.57 for insomnia), perception of not having the proper protective equipment (OR = 1.71 for symptoms of depression and OR = 1.57 for symptoms of anxiety) and being a woman (OR = 1.39 for anxiety). ConclusionsHealthcare professionals can suffer a significant mental condition that may require psychiatric and psychological intervention. The main associated factors are primarily related to living and working in cities with a higher number of cases and the characteristics of the job, such as being a postgraduate doctor, as well as the perception of security. The main risk factors are primarily related to geographical distribution and job characteristics, such as being a resident physician and self-perception of safety. Further studies are required as the pandemic evolves.
