Effect of Noise Exposure During Orthopedic Surgery on Nurses' Information Processing: Analysis of Reaction Delays and Errors in Judgment.

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
Objective Orthopedic surgeries generate high noise levels that exceed recommended thresholds, thereby posing risks to surgical safety. Nurses play a critical role in instrument preparation and intraoperative monitoring. However, evidence of noise-induced cognitive impairment in this population remains limited. This study evaluated the effects of intraoperative noise exposure on nurses' reaction times and error rates during orthopedic procedures.
methodsThis retrospective study analyzed data from 200 orthopedic surgeries conducted in a tertiary hospital over 12 months. Noise levels in the operating rooms (ORs) were recorded using calibrated noise meters. Nurses' cognitive performance was assessed by measuring reaction time and error rate. Baseline demographic and clinical data, such as age, experience, gender, and surgery type, were included. Correlation analysis and multivariate regression were performed to assess the relationships among noise levels, reaction time, and error rates.
resultsThe average noise level in the ORs was 89.73 ± 11.52 dB (range: 60-120 dB). Noise levels showed significant positive correlations with reaction delays (r = 0.54, P < 0.01) and error rates (r = 0.68, P < 0.01). Nurses exposed to noise levels exceeding 100 dB had an average reaction time of 274.82 ± 45.80 ms, compared with 261.48 ± 47.63 ms in quieter environments. Error rates increased sharply beyond 100 dB, with a mean of 0.91% ± 0.05%, compared with 0.61% ± 0.04% at lower noise levels. Multivariate logistic regression analysis confirmed noise as an independent risk factor for delayed reaction time and increased error rate.
conclusionNoise exposure during orthopedic surgeries significantly affects nurses' information processing, increasing reaction times and error rates. Noise mitigation strategies are essential to enhance OR safety and nursing performance.
