All acute care hospitals in Kentucky were invited to participate in the project. A case of sCAP was defined as a patient admitted to an ICU with the physician diagnosis of CAP. Upon patient identification, demographic and clinical characteristics were entered into an Internet-based data collection form. All patients had a nasopharyngeal swab sent to the University of Louisville Infectious Diseases Reference Laboratory for identification of viral pathogens. The Luminex xTAG respiratory viral panel multiplex PCR was used for viral identification. Clinical cultures were utilized to identify bacterial and fungal causes of sCAP. Statistical Process Control (SPC) charts were used to identify outbreaks. Chloropleth maps were used for spatial analysis. Each analytical mechanism was provided in real-time via the study website.
