SESSION TITLE Not the Normal Host Infections Still Matter SESSION TYPE Rapid Fire Original Inv PRESENTED ON 10/17/2022 1215 pm - 115 pm

PURPOSE:

The purpose of this study is to determine the incidence of hospital acquired and ventilator associated pulmonary infections in patients on ECMO for SARS-CoV-2 related ARDS in relation to steroids and ECMO cannulation days.

METHODS:

A retrospective analysis of COVID19 patients treated with ECMO admitted to a tertiary care academic medical center from January 2020 until July 2021 was conducted. Data including baseline patient characteristics, type, and duration of ECMO support, type and days of steroids use and sputum culture results were collected. An institutional review board (IRB) approval was obtained prior to data collection. A two-tailed T-test was used to calculate the P-value, P-value of <0.05 was considered significant.

RESULTS:

A total of 34 patients were included in the analysis, of which 3 of them were on (Veno-Arterial) VA-ECMO and 31 were on (Veno-Venous) VV-ECMO. 32 out of 34 (94%) patients received steroids during their hospital course. Total of 20 patients had positive sputum cultures (59%) and average steroid days for patients with positive sputum cultures was 20.75 days as compared to 10.75 days for patients with negative sputum cultures (P-Value 0.01). Average ECMO days for patients with positive sputum cultures was 26 days as compared to 14.4 days for patients with negative sputum cultures (P Value 0.0003). Amongst the patients with positive sputum cultures, pseudomonas aeruginosa and methicillin-sensitive staphylococcus aureus (MSSA) were the most isolated organisms (25% of positive cultures), methicillin-resistant staphylococcus aureus (MRSA) and Serratia Marcescens were isolated in 20% of positive cultures, Klebsiella aerogenes was isolated in 15% of positive cultures.

CONCLUSIONS:

Hospital acquired and ventilator associated pulmonary infections are common in patients on ECMO for SARS-CoV2 related ARDS. Longer ECMO days and a longer duration of steroid use were found to be associated with higher rates of bacterial growth in sputum cultures. Common organisms included Pseudomonas, MSSA, and MRSA. CLINICAL IMPLICATIONS Our analysis describes the most common bacterial organisms isolated on sputum cultures in this study population. It may also serve as a guide for empiric antibiotics choice when bacterial pneumonia is suspected in similar patients while awaiting sputum culture results.
