Post-Traumatic Stress Disorder and Burnout in Healthcare Professionals During the SARS-CoV-2 Pandemic: a Cross-Sectional Study.

INTRODUCTION: Healthcare professionals who are directly involved in the diagnosis, treatment, and general care of patients with SARS-CoV-2 are at risk of developing adverse psychological reactions. A cross-sectional study of healthcare professionals aimed to determine the impact of the SARS-CoV-2 pandemic on the mental health of healthcare professionals in two of the largest referral hospitals in Athens, Greece. METHODS: The study was conducted in the two largest SARS-CoV-2 referral hospitals in Athens, Greece. An assessment and the interrelationship of post-traumatic stress disorder, using the Impact of Event Scale-Revised [IES-R]) and burnout, using the Maslach Burnout Inventory [MBI]) was carried out. RESULTS: A total of 162 subjects were enrolled in the study. Fifty-six (35%) had an IES-R score > 33, suggesting post-traumatic stress disorder. Forty-nine (30%) had an MBI score > 27. Seventy-five (46%) had a personal accomplishment score of < 33 and 46 (28%) had a depersonalization score >10. Stepwise backward logistic regression revealed that the only independent variable that was retained regarding the presence of post-traumatic stress disorder was the emotional exhaustion score of the MBI (at a cut-off of 24 in this scale, the 95% CI of the odds ratio for the presence of post-traumatic stress disorder was 1.077-1.173). CONCLUSIONS: In this sample of first-line Greek healthcare professionals against SARS-CoV-2, most of them were proven to be quite resilient to this challenge. One-third of them had post-traumatic stress disorder, which depended on their degree of emotional exhaustion. Healthcare professionals, as represented by this study, performed their duties without feeling helpless and developing adverse psychological reactions.

Hospital Resources May Be an Important Aspect of Mortality Rate among Critically Ill Patients with COVID-19: The Paradigm of Greece.

For critically ill patients with coronavirus disease 2019 (COVID-19) who require intensive care unit (ICU) admission, extremely high mortality rates (even 97%) have been reported. We hypothesized that overburdened hospital resources by the extent of the pandemic rather than the disease per se might play an important role on unfavorable prognosis. We sought to determine the outcome of such patients admitted to the general ICUs of a hospital with sufficient resources. We performed a prospective observational study of adult patients with COVID-19 consecutively admitted to COVID-designated ICUs at Evangelismos Hospital, Athens, Greece. Among 50 patients, ICU and hospital mortality was 32% (16/50). Median PaO2/FiO2 was 121 mmHg (interquartile range (IQR), 86-171 mmHg) and most patients had moderate or severe acute respiratory distress syndrome (ARDS). Hospital resources may be an important aspect of mortality rates, since severely ill COVID-19 patients with moderate and severe ARDS may have understandable mortality, provided that they are admitted to general ICUs without limitations on hospital resources.

Lactate Kinetics Reflect Organ Dysfunction and Are Associated with Adverse Outcomes in Intensive Care Unit Patients with COVID-19 Pneumonia: Preliminary Results from a GREEK Single-Centre Study.

Coronavirus disease-19 (COVID-19) continues to be a health threat worldwide. Increased blood lactate is common in intensive care unit (ICU) patients; however, its association with outcomes in ICU COVID-19 patients remains currently unexplored. In this retrospective, observational study we assessed whether lactate is associated with outcomes in COVID-19 patients. Blood lactate was measured on ICU admission and thereafter daily up to day 14 in 45 patients with confirmed COVID-19 pneumonia. Acute physiology and chronic health evaluation (APACHE II) was calculated on ICU admission, and sequential organ failure assessment (SOFA) score was assessed on admission and every second day. The cohort was divided into survivors and non-survivors based on 28-day ICU mortality (24.4%). Cox regression analysis revealed that maximum lactate on admission was independently related to 28-day ICU mortality with time in the presence of APACHE II (RR = 2.45, p = 0.008). Lactate's area under the curve for detecting 28-day ICU mortality was 0.77 (p = 0.008). Mixed model analysis showed that mean daily lactate levels were higher in non-survivors (p < 0.0001); the model applied on SOFA scores showed a similar time pattern. Thus, initial blood lactate was an independent outcome predictor in COVID-19 ICU patients. The time course of lactate mirrors organ dysfunction and is associated with poor clinical outcomes.
