Enhancement of the capacity of a healthcare team through real-time information-sharing using a wireless intercom system: a prospective simulation study.
Observational study in BMJ open, 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
objectivesRising patient numbers and limited resources are creating a challenging environment for healthcare providers recently. Anaesthesiologists are also increasingly faced with complex situations, requiring high adaptability in the operating room. To enhance team adaptability during emergencies, effective communication methods are essential. This study aimed to compare the impact of mobile phones and intercoms on the response time and effectiveness of anaesthesiologist teams in emergency situations.
designProspective, observational and simulation study.
settingAnaesthesiology and Critical Care, Yokohama City University Medical Center, Yokohama, Japan. PARTICIPANTS AND
methodsThis study, conducted at Yokohama City University Medical Center (Yokohama, Japan), evaluated how communication methods (intercoms vs mobile phones) impact the efficiency of anaesthesiologists in the simulation setting. Two scenarios were tested: (1) retrieving a video laryngoscope during a difficult intubation and (2) gathering support during cardiac arrest. PRIMARY AND SECONDARY OUTCOME MEASURES: Outcomes measured included time to secure equipment, time for assistance to arrive and staff numbers gathered. The Wilcoxon signed-rank test was used to compare the outcomes between the intercom and mobile phone groups.
resultsIn scenario 1, the time to secure the video laryngoscope was significantly shorter with intercom use compared with mobile phones (intercom vs mobile phone, median (IQR): 29 (25-33) s vs 50 (39-62) s; p=0.013, effect size 20 (95% CI 7 to 31)). In scenario 2, the time from the request for assistance until the first supporting staff member reached the operating room was significantly shorter in using the intercoms (intercom vs mobile phone, median (IQR): 16 (14-18) s vs 35 (31-38) s; p=0.04, effect size 17 (95% CI 6 to 24)), and more personnel were available in the intercom group (intercom vs mobile phone, median (IQR): 3 (3-3.5) persons vs 2 (1-2) persons; p=0.04, effect size 1.5 (95% CI 1 to 3)).
conclusionReal-time information sharing through intercoms improved the ability of the anaesthesiologist team to respond more rapidly and effectively in emergency situations, enhancing overall team adaptability. This approach may improve patients' outcomes by shortening response times and increasing team coordination.
