Introduction:
Surveillance is necessary for bloodstream infection control. Daily monitoring of the central venous catheter (CVC) use, a time-demanding process, is the standard denominator to calculate the infection rate; surveillance of only one day per week has been proposed as alternative.
Objective:
To determine whether surveillance of one day per week is similar to daily monitoring in a second-level hospital.
Material And Methods:
Daily monitoring of CVC utilization ratio was done during nine weeks in four locations of a second-level hospital. For each day, proportional differences respect to the global CVC utilization ratio was estimated. An ANOVA test was done to find differences between each weekday.
Results:
CVC usage surveillance was performed for 9 weeks, so nine determinations were obtained for each weekday. No significant differences were found between each day (F = 2.20, p = 0.056). The lowest sampling discrepancy was found on Wednesdays.
Conclusions:
According to previous studies, and our own data, monitoring the CVC use one day per week is a reasonable alternative to the daily surveillance.
Insights
Weekly central venous catheter (CVC) use surveillance is a viable alternative to daily monitoring for bloodstream infection control. This method reduces time demands while maintaining accuracy in infection rate calculations.
Area of Science:
- Infection Control and Hospital Epidemiology
- Public Health Surveillance
Context:
- Bloodstream infections (BSIs) necessitate robust surveillance systems.
- Central venous catheter (CVC) utilization is a key metric for BSI rate calculation.
- Daily monitoring of CVC use is resource-intensive.
Purpose:
- To evaluate the efficacy of weekly CVC use surveillance compared to daily monitoring.
- To determine if a reduced surveillance frequency impacts BSI rate accuracy.
- To assess the feasibility of alternative surveillance strategies in healthcare settings.
Summary:
- A nine-week study monitored CVC utilization ratios across four locations in a second-level hospital.
- Statistical analysis (ANOVA) revealed no significant differences in CVC utilization between weekdays.
- Wednesday emerged as the weekday with the lowest sampling discrepancy for CVC use.
Impact:
- Weekly CVC surveillance offers a practical and efficient alternative to daily monitoring.
- This approach can optimize resource allocation in infection control programs.
- Findings support the adoption of less frequent surveillance without compromising BSI control efforts.
