Figure 2. Study Inclusion Flowcharts.

^aAn immediate hospital admission occurring on the same day as the index visit (or 1 day after an emergency department [ED] index visit) did not allow for adequate time to communicate the respiratory syncytial virus (RSV) diagnosis to the patient and consider outpatient management.

^bContinuous enrollment for at least 180 days before the visit date and at least 28 days continuous enrollment after the visit date (censored for death) was required for inclusion into the study.

^cOnly the first outpatient visit for RSV per person per RSV season was included as an index visit for this study.
