Prevalence of and risk factors for intravenous catheter infection in hospitalized cattle, goats, and sheep.

Abstract

BACKGROUND: Intravenous catheter (IVC) use in hospitalized ruminants is a common procedure. Limited information is available describing complications associated with IVCs. HYPOTHESES: Prevalence of IVC infections in hospitalized ruminants is >50%. Intravenous catheters maintained for >5&#x2009;days are more likely to be infected than those maintained for <5&#x2009;days. Intravenous catheters placed non-aseptically have a higher risk for infection than those placed aseptically. ANIMALS: Thirty-four cattle, 39 goats, and 33 sheep were hospitalized in a university teaching hospital. METHODS: Prospective observational study. The IVCs from cattle, goats, and sheep admitted for medical and surgical procedures were randomly selected and submitted for bacteriological culture and susceptibility testing. RESULTS: Prevalence values (95% confidence interval) of infected catheters were 61.8 (45.5, 78.1), 51.3 (35.3, 66.7), and 42.4% (25.2, 58.8) in cattle, goats, and sheep, respectively. Coagulase-negative Staphylococcus spp was the most frequently isolated bacterium. Catheter type/placement technique was a significant (P = .03) predictor of IVC infection in goats but not in cattle (P = .65) and sheep (P = .47). Antibiotic use and reason for catheter placement were not significant predictors of IVC infection in all species. Catheters maintained for >4&#x2009;days had a higher likelihood of being infected than those maintained for <4&#x2009;days in all species. CONCLUSIONS AND CLINICAL IMPORTANCE: Clinicians should consider replacing catheters maintained for >4&#x2009;days to reduce IVC infection.
