Clinical Differences Between Survivors and Non-Survivors of Ventilator-Associated Pneumonia: The Roles of Sulbactam/Ampicillin and Methicillin-Resistant .

BACKGROUND

Ventilator-associated pneumonia (VAP) is one of the most lethal complications in intensive care unit (ICU) patients. However, critical issues of non-survivors vary and are still unclear in VAP patients.

METHODS

The clinical differences between survivors and non-survivors of VAP were retrospectively analyzed in patients hospitalized from April 2023 to March 2024.

RESULTS

Of a total of 42 VAP patients, 22 (52.4%) survived, and 20 died. Survivors were significantly younger (69.1 vs 71.7 years, p < 0.01) and received sulbactam/ampicillin (SAM) as the initial antibiotics, significantly more (45.5% vs 10%, p = 0.006) than non-survivors. The male/female ratio and wards where they were managed were similar in both groups, but methicillin-resistant (MRSA) was detected significantly more frequently in non-survivors (4/4 = 100%).

CONCLUSION

These data suggest that VAP patients who survived were younger and received treatment with narrow-spectrum antibiotics, such as SAM. Isolation of MRSA might be critical. These findings could influence antibiotic protocols and ICU management strategies to prevent infection with resistant bacteria to improve the prognosis of patients with VAP.
