Background

Same-day surgery cancellation results in decreased operating room (OR) utilization, reduced productivity, and inconvenience for patients. We aim to assess the cancellation rates of elective surgeries, identify common causes, and evaluate changes due to the COVID pandemic.

Methods

A retrospective cohort study was conducted identifying all same-day surgery cancellations at a tertiary pediatric academic hospital from 1/1/2015 to 12/31/2017 (pre-COVID) and from 4/1/2020 to 3/31/2021 (post-COVID). Statistical analysis was performed using generalized regression with cancellation as the dependent variable. Period, age, ethnicity, gender, preferred language, and insurance were independent variables.

Results

There were 55465 scheduled cases (41670 before and 13795 after COVID), with 1508 cancellations (2.7%). Of those, 1247 (3.0%) were before COVID and 261 (1.9%) after COVID (p < .001). Of all cases, 56.7% (31475) were male, 55.1% (30595) were non-Hispanic/Latinx whites, 82.3% (45638) spoke English, and 45.5% (25237) had public insurance. The mean age was 8.5 years (SD = 6.03).The decrease in the probability of cancellation was most significant in patients with public insurance, < 1 year-of-age, Hispanic/Latinx who spoke Spanish (pre-pandemic = 4.9% [CI = 4.2%-5.8%]; pandemic = 2.8% [95% CI = 1.9%-4.0%]. Regardless of the period, Hispanic/Latinx patients and those with public insurance had higher rates of surgery cancellations (p < .001).

Conclusion

There was a significant decrease in same-day cancellations post-pandemic. We hypothesize that the required pre-operative COVID test helped to minimize same-day cancellations. Increased communication and education enhanced family engagement and was critical for improved OR metrics, including cancellation rates.
