Abstract

Objective: We aimed to identify the risk factors associated with 30-day mortality in patients with methicillin-resistant Staphylococcus spp. (MRS) pneumonia.
Material and Methods: From March 2021 to March 2023, we conducted a prospective, observational study at Cho Ray Hospital, Viet Nam, in hospitalized patients aged ≥18 years with pneumonia due to MRS. To assess the risk factors for 30-day mortality, we performed univariable and multivariable logistic regression analyses.
Results: The 30-day mortality was 39.1% (36 out of 92 patients with MRS pneumonia). The risk factors for death within 30 days in cases with MRS pneumonia were severe pneumonia, being overweight, respiratory failure, shock, or having a medical device (a tracheostomy or endotracheal tube, a central venous catheter, a urinary catheter, or a nasogastric tube). The 30-day mortality increased proportionally with the number of risk factors.
Conclusion: Pre-existing factors were associated with the 30-day mortality risk of MRS pneumonia. Therefore, comprehensive therapy, including initial anti-MRS treatment, might be important for improving outcomes in patients with the studied risk factors.
