      The population of older adults who live in long-term care facilities (LTCFs) is at a particularly high risk for influenza exposure and associated harms.

      Quantifying influenza exposure within California hospitals and nursing homes using administrative data.
      When influenza is detected within an LTCF, the Centers for Disease Control and Prevention recommends that antiviral chemoprophylaxis be initiated as soon as possible for all residents on affected wings and continued for a duration of 14 days or until at least 7 days after the last resident's onset of illness.

      Clinical practice guidelines by the Infectious Diseases Society of America: 2018 update on diagnosis, treatment, chemoprophylaxis, and institutional outbreak management of seasonal influenza A.
      To what degree LTCFs adhere to this national guideline during outbreaks is unknown. As part of facility-specific outbreak control protocols, LTCF staff may also develop their own antiviral chemoprophylaxis policies. Few data describe the existence of these policies or their alignment with national guidelines. Without this information, it is difficult to develop interventions to improve the use of antiviral chemoprophylaxis in response to influenza outbreaks to mitigate harm in this vulnerable population. To address this gap, we examined LTCF staff adherence to national guidelines, variation in self-established chemoprophylaxis policies, and LTCF staff adherence to these policies during influenza outbreaks.
