SESSION TITLE: Critical Care Management of COVID-19 SESSION TYPE: Original Investigations PRESENTED ON: 10/17/2022 01:30 pm - 02:30 pm PURPOSE: Superimposed bacterial co-infection is common among patients with Coronavirus disease-19 (COVID-19) pneumonia. Incidence of any superimposed infection ranges from 0% to 40%. Up to 50% of COVID-19 patients who died, had concomitant bacterial or fungal infection. Steroids are recommended for the treatment of acute hypoxemic respiratory failure (AHRF) due to COVID-19 and are thought to mitigate inflammatory organ injury. This retrospective study explores a subset of COVID-19 patients receiving Epoprostenol (iEPO) for AHRF and compared two different steroid treatment strategies and the impact on patient outcomes. METHODS: This is a retrospective study of 101 COVID-19 patients with AHRF receiving iEPO and systemic steroids. Patients in the high dose steroid group (n=59) received a minimum of dexamethasone 20mg daily or solumedrol 100mg daily while the standard dose steroid group (n=52) were those who received any lower dose. Patients that were DNR/I were excluded from the study. The primary outcome of the study was the rate of bacterial co-infection defined by positive cultures. Secondary outcome was mortality. RESULTS: Results showed that patients treated with high dose steroids were older (66.77±11.17 vs 60.33±14.49, p0.006) and received a longer treatment course (18 days (12-25) vs 12.5 days (10-17), p 0.004). Univariate and Multivariate analysis showed that higher dose steroids were not associated with increased risk of superimposed bacterial infection (OR 0.96, CI (0.34-2.66), p0.93). The duration of steroids, regardless of the dose, was associated with increased risk of superimposed bacterial infection (OR 1.06, CI (1.01-1.13), p0.033). When adjusted for comorbidities and inflammatory state, there was no significant difference in mortality between patients treated with high dose compared to standard dose steroids (OR 3.60, CI (0.65-19.93), p0.14). A longer duration of steroids was associated with a trend towards improved mortality (OR 0.93, CI (0.87-1.00), p0.072). CONCLUSIONS: Our study suggests that the duration of steroids, rather than dosage, had an effect on patient outcomes. There was no difference in bacterial co-infection rates between the two groups, but infection rates were increased among those who received a longer course of steroid treatment. There was a trend towards lower mortality with increased steroid duration, however, this did not reach statistical significance. Given this trend towards lower mortality, future prospective studies should investigate steroid duration to determine if a longer course of treatment leads to better outcomes in patients with COVID-19 pneumonia and refractory AHRF. CLINICAL IMPLICATIONS: Based on our study, patients should not receive a higher dose or longer duration of steroid treatment given the increased risk of bacterial infection with no definitive improvement in mortality.
