What should the threshold rate for infection surveillance be?

The threshold rate for infection surveillance should be high enough to incorporate natural variation because this approach allows for a more accurate representation of infection rates within a facility. Infection rates can naturally fluctuate due to seasonal trends, changes in resident population, or variations in healthcare practices. By setting a threshold that accounts for these natural variations, healthcare providers can better distinguish between true outbreaks and routine fluctuations in infection rates. This aids in prioritizing interventions and resources effectively while ensuring that the focus remains on significant and actionable data rather than being influenced by minor, inconsequential variations that could lead to misdirected efforts or unnecessary alarms. Balancing sensitivity and specificity in surveillance metrics is crucial for effective infection control and the overall health of residents.
