Risk factors for mortality and complications in peripheral venous catheter-associated Staphylococcus aureus bacteraemia: a large multicentre cohort study
Background
Peripheral venous catheter-associated Staphylococcus aureus bacteraemia (PVC-SAB) is a potentially life-threatening nosocomial infection.
Aim
This cohort study aims to identify the risk factors associated with its mortality and complications.
Methods
Retrospective analysis of a prospective cohort study conducted at two tertiary-care hospitals in Spain. Adult patients admitted between January 2011 and July 2019 which developed PVC-SAB during their hospital stay were included. Primary outcome was all-cause 30- and 90-day mortality. Secondary outcomes were sepsis or septic shock at the onset of bacteraemia, metastatic infection and length of hospital stay. Univariate and multivariate analyses were performed.
Findings
A total of 256 PVC-SAB were diagnosed in 243 patients between 2011 and 2019. Thirty-day and 90-day all-cause mortality were 18.3% and 24.2%, respectively. Lack of susceptible antibiotic administration the day after blood culture collection (odds ratio: 4.14; 95% confidence interval: 1.55–11.03; P = 0.005), sepsis and complicated bacteraemia were identified as independent risk factors for 30- and 90-day mortality; meticillin-resistant S. aureus bacteraemia was identified as an independent risk factor only for 30-day mortality and functional dependence only for 90-day mortality. Persistent bacteraemia and sepsis were associated with septic metastases, which significantly increased hospital stay, and endocarditis. A greater proportion of patients experiencing septic shock were subsequently institutionalized compared to those without.
Conclusion
PVC-SAB remains linked to high mortality rates. Prompt administration of appropriate antibiotics is crucial for lowering mortality. A comprehensive diagnostic approach is essential, especially in patients with persistent bacteraemia and implanted cardiovascular devices, to rule out metastatic complications and endocarditis.
