Impact of the COVID-19 pandemic on a pediatric cardiovascular surgery program of a public hospital from Argentina.

Objective To describe the impact of the COVID-19 pandemic on a pediatric cardiovascular surgery program and estimate the necessary time to reduce the surgery waiting list. Methods Retrospective, descriptive study. Surgical outcomes from the pre-COVID-19 period and COVID-19 period were compared. A mathematical model was used to estimate the time necessary to reduce the waiting list. Results Between March 23rd and August 31st, 2020, 83 patients underwent surgery, accounting for a 60 % reduction compared to the pre-COVID-19 period. Their median age was 6 months (interquartile range [IQR]: 25-75, 1.8 months to 2.9 years; p = 0.0023). The time necessary to eliminate the waiting list ranges from 10 to 19 months. Conclusions There was a 60 % reduction in the program. The time required to clear the backlog of cases may range from, at least, 10 to 19 months.
