This is a good example of when “virtual” locations is the best option for mapping.  If there are beds designated for pediatric patients, we recommend a virtual pediatric location be mapped for the pediatric beds (one location) and the other beds mapped as the most appropriate adult unit (second location).  Data is collected and reported to NHSN separately.  If your facility can operationalize this option, it offers the most appropriate data collection and reporting.  If the facility is unable to operationalize this type of data collection in this unit, the unit should be mapped as the appropriate type for the age group (specifically, pediatric or adult) that holds the majority in that unit.
