- Presenter: Katie Lee, PhD, EIS officer assigned to the California Department of Public Health (ID), Division of Communicable Disease Control
What did we do?
- We examined demographic characteristics, morbidity, and risk factors for mortality among adults, excluding pregnant women, hospitalized with listeriosis in California to guide prevention efforts.
What did we find?
- We identified 1,791 hospitalizations with listeriosis; median patient age was 69 years and 52.3% were female.
- The most frequently reported race and ethnicity were Non-Hispanic White (49%) and Hispanic (24%).
- Median length of hospitalization was 8 days. In total, 884 (49%) patients required mechanical ventilation or blood pressure support.
- The proportion of patients who died (14%) increased with age. Patients with cardiovascular, liver or chronic kidney disease, or immunocompromised status had significantly higher odds of death than those who did not.
Why does it matter?
- Listeriosis led to severe morbidity and mortality among older adults in California.
- Death during hospitalization for listeriosis was associated with certain underlying conditions.
- Enhancing efforts to prevent listeriosis among people with these risk factors could decrease in-hospital deaths.
