Post-traumatic stress disorder, depression and anxiety symptoms in COVID-19 outpatients with different levels of respiratory and ventilatory support in the acute phase undergoing three months follow up

Background: The well-known COVID-19 pandemic totally transformed people's lives, paving the way to various psychopathological symptoms. In particular, patients may experience a short- and long-term decreasing in their wellbeing. In this vein, the aim of this paper is to assess the COVID-19 patients' psychopathological profile (Post Traumatic Stress Disorder, distress, anxiety and depression symptoms), detecting possible differences linked to the ventilatory treatments. Methods: Outpatients who recovered from COVID-19 were asked to provide socio-demographic and clinical information, and to complete a brief psychological screening evaluation (Impact of Event Scale-Revised - IES-R, Depression Anxiety Stress Scale - DASS-21). Results: Overall, after informed consent, 163 Italian patients took part in this research. Of them, 31,9% did not undergo any ventilatory therapy, 27,6% undertook oxygen therapy; 28,2% underwent noninvasive mechanical ventilation and 12.3% received invasive mechanical ventilation. Although no statistically significant differences were revealed among patients stratified by spontaneous breathing or ventilatory therapies, they reported statistically significant more depression (4.5+5.2 vs 3.5+3.2; p=.017) and anxiety (4.3+4.5 vs 2.4+2.6; p<.00001) symptoms than normative groups. Moreover, patients experiencing COVID-19 disease as a trauma, complained statistically significant higher levels of depression, anxiety and stress symptoms than who did not describe a clinically relevant traumatic experience (p<0.001). Conclusions: Thus, this study suggests to healthcare professionals to consider COVID-19 experience as a potential real trauma for patients and underlines the necessity to define patients' psychopathological profile in order to propose tailored and effective preventive and supportive psychological interventions.
