The self-reported ISAR tool did not discriminate well between older adults with or without 30-day hospital revisit or death. An optimum score of ≥2 would identify many older adults at no apparent increased risk of poor outcomes at 30 days. Using objective ISAR-related risk factors did not improve overall discrimination.

Appropriate influenza testing and treatment increased to 90% in children with ILI during the 2014-2015 season. Improvements were sustained in a subsequent influenza season. Our initiative improved recognition of influenza and likely increased treatment opportunities. Future work should be focused on wider implementation and further reducing variation.
