Which of the following statements about infection surveillance in nursing homes are true?

The statement that the surveillance plan should include standard definitions and data collection methods is true because a well-structured surveillance system is essential for accurately identifying and monitoring infections within a nursing home setting. Standard definitions ensure consistency in identifying infections, which helps in comparing data over time and across different facilities. Having clear data collection methods is equally important, as it ensures that the information gathered is reliable and valid, enabling effective analysis and interpretation. This structured approach is crucial for identifying trends, understanding epidemiological patterns, and implementing appropriate infection control measures.

The other options do not align with best practices for infection surveillance. Relying solely on staff feedback may lead to biases and incomplete data. Limiting surveillance to only twice a year can result in missed opportunities to identify infection outbreaks or trends that could inform timely interventions. Furthermore, stating that surveillance data is unnecessary undermines the foundational purpose of infection control, which is to protect residents and staff by using data to inform decision-making and action.
