    Patients receiving virtual transition of care (VToC) follow-up had a significantly lower 30-day readmission rate compared to those without follow-up.

  • 2

    Survivor treatment selection bias may affect the observed association between VToC follow-up and reduced readmissions.

  • 3

    Early readmissions were disproportionately categorized in the non-VToC group, leading to an overestimation of readmissions in that group.

  • 4

    Conventional risk adjustment methods cannot fully correct for bias caused by outcome-dependent exposure assignment.

  • 5

    Temporal concordance is essential when assessing exposure and outcome in studies of virtual or postdischarge interventions.
