Impact of COVID-19 on Oncologic Surgical Scheduling: A Retrospective Evaluation from 2017 to 2021 in Saltillo, Coahuila, Mexico

Abstract Background: The COVID-19 pandemic has disrupted healthcare systems worldwide, impacting elective and oncologic surgical services. This study evaluates the effect of the pandemic on oncologic surgery scheduling, volume, and outcomes in two major public hospitals in Saltillo, Coahuila, Mexico. Methods: A retrospective, cross-sectional analysis was conducted using data from 2017 to 2021 from the afternoon oncologic surgery schedules of the IMSS General Hospital and the ISSSTE High-Specialty Hospital in Saltillo. Surgical volume, patient demographics, waiting times, and cancellations were analyzed. Oncology surgeries were never suspended during the study period. Results: A total of 1,001 patients underwent surgery (833 IMSS, 168 ISSSTE; 801 women, 200 men). Breast cancer was the most common diagnosis (n = 472). Annual surgical volume decreased markedly during the pandemic (2020: 125; 2021: 120) compared with 2019 (296). Mean waiting times decreased slightly during the pandemic. Only a few surgeries were postponed or canceled, primarily due to patient-related factors. No perioperative COVID-19 infections were recorded. Conclusions: Despite decreased patient volume, oncologic surgeries continued safely during the COVID-19 pandemic. Strict protective measures enabled effective cancer care in hospitals designated for COVID-19, emphasizing the importance of maintaining essential oncology services during public health crises.
