Highlights
ONS use among 1181 older patients with COVID-19 was retrospectively studied.
ONS use was associated with a lower risk of in-hospital death.
Early ONS could also reduce hospital length of stay and days of viral clearance.
Timely nutritional support is important for COVID-19 geriatrics.

Abstract
Background: The effect of and optimal timing for initiating oral nutritional supplement (ONS) on
hospitalized older patients with the Omicron variant infection remain unclear.
Methods: We collected data from confirmed COVID-19 patients between April 2022 to June 2022 at
Shanghai Fourth People’s Hospital, one of the designated medical centers for COVID-19 in Shanghai,
China. Patients were identified as ONS users or non-ONS users, and the former was further defined as
early ONS (ONS initiated within 48h from hospital admission), and late ONS (ONS initiated after 48 h)
users. We conducted a retrospective cohort design as primary analysis and a case-control design as
sensitivity analysis to explore the associations between ONS and clinical outcomes.
Results: A total of 1181 hospitalized patients ≥60 years old were included in our study. The mean age of
the entire cohort was 78.0, and most patients were female (57.7%). The mortalities after PSM were 1.2%
and 4.3% in the ONS group and non-ONS groups, respectively (P = 0.032). Subgroup analysis results
showed that patients with early-ONS had significantly shorter hospital..
