Real-world data–driven insights into the clinical and economic burden of serious infections in routine practice

Hospital-onset infections place a substantial and often underestimated burden on patients and healthcare systems. For hospital-onset methicillin-resistant Staphylococcus aureus non-ventilator-associated pneumonia (MRSA NVAP), real-world evidence (RWE) on clinical and economic impact has been limited, particularly given changes in hospital practice patterns and patient complexity since 2020.
A new study from Premier Applied Sciences, selected as a Research Podium presentation at ISPOR 2026, draws on data from more than 1400 US hospitals via the Premier Healthcare Database to quantify that burden across 2023 to 2025.
Compared with other non-ventilator-associated pneumonias, patients with MRSA NVAP experienced more than three times the length of stay, were over four times more likely to require ICU admission, and incurred excess costs of more than $75,000 per hospitalization. Around one in five patients did not survive their initial admission. Among those who did, nearly half were readmitted within 180 days, with most readmissions occurring within the first month after discharge.
In this interview, study authors Chendi Cui, Laura Curry, and Ning An Rosenthal of Premier Applied Sciences discuss:
- What the findings reveal about clinical burden and ongoing resource use beyond the initial admission
- Gaps in post-discharge care and the factors driving readmission
- How hospitals can better identify patients at higher risk
- Planned next steps
Read the full interview to explore the findings and their implications for clinical practice.
