Surgical interruptions and preventable delays in the operating rooms of academic teaching hospitals.

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
backgroundOperating rooms are complex environments prone to delays and interruptions, which are linked to human error and adverse patient outcomes. Since more than half of the hospitals in Iran are teaching hospitals, understanding these delays and interruptions is crucial to prevent them. This observational study aimed to assess the lost time and causes for surgical interruptions and delays in Iranian academic teaching hospitals.
methodsThis cross-sectional observational study was conducted in five teaching hospitals in Iran during July and August of 2025. A total of 251 surgeries were randomly observed using full-case non-participant observation. Data were collected using a chronometer and standardized forms. Causes of delays and interruptions were categorized through directed content analysis. Quantitative data were analyzed with statistical package for social science (SPSS) version 24. The primary outcome was total lost time per surgery. The secondary outcomes were frequency and duration of interruptions and delays, as well as the distribution of causes.
resultsOut of 50,675 observed minutes, 7,920 min (16.83%, Confidence Interval 95%: 14.62–19.04) were lost due to interruptions and delays. A total of 281 delays with 319 causes were recorded and classified into five categories: operating room staff (172 times), staff outside the operating room (21), instruments and devices (60), patients (33), and managerial issues (33). Notably, 14.1% of causes were related to the educational nature of the hospitals, involving residents and trainees.
conclusionsSurgical interruptions and delays happen frequently and may reduce operating room efficiency and threaten patient safety. Delays related to residents and trainees require further investigation considering overall operating room efficiency. Educational, managerial, and instrument-related interventions may reduce lost operating room time. The findings may be generalizable to academic teaching hospitals.
