Beyond the Cancellation: Identifying Avoidable and Non-avoidable Causes of Elective Operation Theatre Cancellations in a Tertiary Care Hospital.
Article in Cureus, 2026. 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
Background Elective operation theatre (OT) cancellations are an important indicator of perioperative quality and healthcare efficiency. Most studies describe the frequency and causes of cancellations without distinguishing between avoidable and non-avoidable events, limiting the identification of actionable targets for quality improvement. This study aimed to classify elective OT cancellations according to avoidability and identify the major modifiable causes. Methods This retrospective observational study was conducted at the All India Institute of Medical Sciences (AIIMS), Nagpur, Maharashtra, India. All elective surgical procedures cancelled after formal OT scheduling between December 2024 and June 2025 were included. Data were obtained from the OT cancellation registry, electronic medical records, anaesthesia records and patient case files. Cancellations were classified as avoidable, non-avoidable or unclassified using predefined criteria. Pareto analysis was performed to identify the principal modifiable causes of avoidable cancellations. Results Of 2,744 scheduled elective procedures, 247 were cancelled, resulting in an overall cancellation rate of 9.0%. Among the cancelled cases, 153 (61.9%) were classified as avoidable, 42 (17.0%) as non-avoidable, and 52 (21.1%) as unclassified because of insufficient documentation. Administrative and scheduling-related factors accounted for the largest proportion of cancellations (46.6%). Lack of OT time was the leading avoidable cause (59.5%), followed by inadequate preoperative preparation (9.2%), OT scheduling/admission-related issues (7.2%), and unavailability of intensive care unit beds (5.2%). Pareto analysis showed that these four factors accounted for over 80% of avoidable cancellations. Conclusion Most elective OT cancellations were attributable to potentially preventable system-related factors. Targeted interventions focusing on OT scheduling, preoperative assessment, multidisciplinary communication and resource planning may reduce avoidable cancellations, improve OT utilization and enhance perioperative care.
