Impact of Early Telemedicine Follow-up on 30-Day Hospital Readmissions

Telemedicine is increasing in popularity but the impact of this shift on patient outcomes has not been well described. Prior data has shown that early post-discharge office visits can reduce readmissions. However, it is unknown if routine use of telemedicine visits for this purpose is similarly beneficial.


During the COVID pandemic the landscape of ambulatory care changed. Routine appointments transitioned from traditional in-person visits to a combination of telehealth and in-person in order to decrease the spread of disease. However, the effect of this transition on clinical outcomes is still emerging.

Material and Methods:

Data extraction and patient sample

After approval by the Columbia University Institutional Review Board (IRB), we queried our EHR (Epic Systems, Verona, Wisconsin, 2020) to identify all adult, non-obstetric, and non-Covid related discharges from Columbia University Irving Medical Center (CUIMC) and NewYork-Presbyterian Allen Hospital between 6/1/2020 to 11/30/2020.

Outcomes definition

We included for analysis all discharges to home setting that also had a completed or cancelled in-person or telemedicine (including video and telephone-only) primary care (defined as an internal medicine or family medicine visit) or cardiology visit within 7 days of discharge; discharges that had readmissions prior to the scheduled follow-up visit or represented a 30-day readmission event were excluded.


In our study of patients discharged from an academic medical center during the period immediately following the widespread telemedicine adoption, we found that those who used telemedicine follow-up visits early after discharge were no more likely to be admitted within 30 days than those whose early follow-up utilized in-person visits.
