Fly rounds: Validation and pilot of a novel epidemiologic tool to guide infection control response to an infestation of Sarcophagidae flies in a community hospital's perioperative department.

During an outbreak of Sarcophagidae, or flesh flies, in a community hospital's perioperative department, the infection prevention and control (IPC) department developed, validated, and piloted a novel epidemiologic tool to track hourly fly prevalence by room. Interrater reliability of the tool was measured as 0.88 and hourly point prevalence counts were superimposed on floor plans to create heat maps. Such surveillance tools allowed more timely decision making in conjunction with the operations of the hospital incident command system.
