Abstract

Abstract: Background: During the coronavirus disease 2019 (COVID-19) pandemic, healthcare facilities (HCFs) were overwhelmed with increasing patient volumes and limited resources. Reports of disruptions in routine practices at HCFs have emerged. We evaluated changes in policies, practices, and programs for antimicrobial stewardship (AMS), infection prevention and control (IPC), and clinical microbiology across six HCF in South America following the onset of the COVID-19 pandemic. Methods: We conducted a survey in 6 HCFs in Argentina, Brazil, and Chile; 2 HCFs in each country. Data on 5 components (facility characteristics, antibiotic procurement and distribution, AMS activities, IPC activities, and clinical microbiology) were collected from designated specialists within each HCF from March 2018 – February 2021. We compared observations within these 5 components pre-pandemic (March 2018 – February 2020) to during pandemic (March 2020 – February 2021.) Results: During the pandemic, the number of ICU beds increased across all the 6 HCFs by 57-633%, and the number of ventilators increased by 15-317% in 5 out of the 6 HCFs. Healthcare personnel shortages were observed in all 6 HCFs, notably common for nurses and laboratory personnel (Table 1). Extended use of N95 respirators was reported across all 6 HCFs with 2 doing extended use of gowns and medical masks. The only PPE reused was N95 respirators in 2 HCFs. Difficulties in cohorting patients with multi-drug resistance organism (MDRO) was reported by one of the HCFs. Three HCFs reported shortages in drugs with coverage for MRSA, gram-negative bacteria, and fungal pathogens despite no reports of interruption in AMS activities in these HCFs. Two hospitals reported delays on microbiology results. Facility characteristics and reported changes during COVID-19 pandemic (March 2020-February 2021) Conclusion: The COVID-19 pandemic led to substantial increases in ICU beds, number of ventilators, and extended use of PPE suggesting increases in admission of severe patients and suboptimal IPC practices in HCFs in South America. It is unclear if shortages in agents commonly used to treat MDRO was related to overuse or access difficulties. Additional evaluation is needed to determine the impact of these findings on antimicrobial resistance and antimicrobial use. Disclosures: Matias Salomao, MD, Cepheid: Lecture.
