Trends in surgery and anesthesia practices during the COVID-19 pandemic: a nationwide analysis from South Korea's Health Insurance Database.
Article in Frontiers in medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: The coronavirus disease 2019 (COVID-19) pandemic has led to significant changes to global healthcare systems, particularly affecting surgical and anesthetic practices. This study investigated nationwide trend in anesthesia and surgery before and during the pandemic. Methods: This retrospective, population-based study analyzed confirmed COVID-19 cases in the Korean National Health Information Database from 2019 to 2021. Anesthesia procedures were categorized into general anesthesia, regional anesthesia, and monitored anesthesia care (MAC). COVID-19 positive patients were defined as those with a confirmed diagnosis within 30 days before and after surgery. We analyzed anesthesia modality, patient characteristics, hospital type and COVID-19 trends. Results: A total of 6,878,556 anesthesia procedures were recorded. The number of procedures decreased slightly in 2020 but increased in 2021. General anesthesia accounted for the majority of procedures. Regional anesthesia, especially brachial plexus block (BPB), and MAC showed an increasing trend. There was a positive correlation between monthly COVID-19 case counts and surgical volume. Most COVID-19 positive patients underwent surgery in general hospitals and received general anesthesia. Conclusion: Despite the pandemic, overall surgical volume in South Korea remained relatively stable compared to global trends. The shift toward regional techniques like BPB suggests adaptation to reduce aerosol-generating procedures. These findings highlight the need for strategic allocation of resources and preparedness planning in future pandemics.
