Braverman A. Improving Team Members' Attention During the OR Briefing or Time Out. AORN J 2024; 119:421-427. [PMID: 38804746 DOI: 10.1002/aorn.14144] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Revised: 09/25/2023] [Accepted: 11/05/2023] [Indexed: 05/29/2024]
Abstract
Effective coordination among health care professionals is crucial to achieving optimal outcomes. In the OR, even minor errors can have catastrophic consequences. To mitigate the risk of error, health care professionals have adopted a briefing culture like that used in the aviation industry. Briefings are essential to ensure that everyone involved in a procedure knows the plan and potential risks and is prepared to perform their duties safely and effectively. The fundamental human sense involved in briefings is auditory perception; although important, hearing alone does not equate to focused attention. To enhance the efficacy of briefings, engaging the use of a second sense by adding a visual checklist may increase attentiveness and the chances of early error detection and prevention. Using a projection device may enhance all team members' engagement and participation during the briefing or time-out process and can be an effective tool for improving communication and reducing errors.

Abstract
Introduction Distractions in operating theatres prevent team members from concentrating on the complex tasks required for a successful operation. This can be a potential hazard to care for, and previously, correlations have been made between increased theatre distractions and adverse events. However, it remains unclear how frequently such events occur during routine care in theatres. The present study aims to quantify distractions and analyse any differences between staff groups, operative stages, and modes of operation. Methods A single-centre prospective study was conducted to assess disruptions in general surgical theatres. Events were recorded using a previously described categorization system on a proforma by a single researcher. The source and severity of distraction were recorded, as well as the mode of operation (elective/emergency), stage of operation, and staff team (scrubbed/floor). Results A total of 4,219 minutes of surgery were observed over four weeks, and 1,095 distraction events were recorded. Of the 14 elective and nine emergency procedures recorded, there was a mean of 54.8 distractions per procedure and a frequency of one distraction every three minutes and 51 seconds (15.6 hr-1). Irrelevant communication relating to the patient's case was the most common source, accounting for 24.7% of all distractions. The most frequently disrupted stage of the procedure for scrubbed staff was during anastomosis/resection for both elective and emergency procedures, with 16.9 and 32.6 distractions occurring per hour, respectively. Scrubbed staff were significantly more susceptible to distraction in emergency procedures than the floor staff. Discussion Our study reflects previous assessments with irrelevant communications and emergency procedures yielding the highest prevalence of distraction. This investigation provides novel information about the different stages of general surgery and the frequency of distractions that occur.

Br J Anaesth 2024; 132:911-917. [PMID: 38336517 PMCID: PMC11103169 DOI: 10.1016/j.bja.2023.12.033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Revised: 12/20/2023] [Accepted: 12/29/2023] [Indexed: 02/12/2024] Open
Abstract
BACKGROUND Anaesthetic drug administration is complex, and typical clinical environments can entail significant cognitive load. Colour-coded anaesthetic drug trays have shown promising results for error identification and reducing cognitive load. METHODS We used experimental psychology methods to test the potential benefits of colour-coded compartmentalised trays compared with conventional trays in a simulated visual search task. Effects of cognitive load were also explored through an accompanying working memory-based task. We hypothesised that colour-coded compartmentalised trays would improve drug-detection error, reduce search time, and reduce cognitive load. This comprised a cognitive load memory task presented alongside a visual search task to detect drug errors. RESULTS All 53 participants completed 36 trials, which were counterbalanced across the two tray types and 18 different vignettes. There were 16 error-present and 20 error-absent trials, with 18 trials presented for each preloaded tray type. Syringe errors were detected more often in the colour-coded trays than in the conventional trays (91% vs 83%, respectively; P=0.006). In signal detection analysis, colour-coded trays resulted in more sensitivity to the error signal (2.28 vs 1.50, respectively; P<0.001). Confidence in response accuracy correlated more strongly with task performance for the colour-coded tray condition, indicating improved metacognitive sensitivity to task performance (r=0.696 vs r=0.447). CONCLUSIONS Colour coding and compartmentalisation enhanced visual search efficacy of drug trays. This is further evidence that introducing standardised colour-coded trays into operating theatres and procedural suites would add an additional layer of safety for anaesthetic procedures.

Abstract
PURPOSE The purpose of the study was to evaluate the psychometric properties of the Disruptions in Surgery Index (DiSI) in operating room health care professionals and to determine the frequency of distractions DESIGN: Methodological study. METHODS The sample consisted of 152 health care professionals. Data were collected online using the DiSI scale. The language validity was ensured, and the data were analyzed with the content validity index, Cronbach α coefficient, and item-total score correlation. Data on distractions of health care workers were given as percentages and averages. FINDINGS The mean age of health care professionals was 27.3 ± 6.0 years, and 77.0% of them were operating room nurses. The content validity index of the scale was found to be 0.95. The Cronbach α coefficient of the scale was 0.953 for frequency, 0.967 for contribution to error, and 0.971 for obstruction of goals. The correlation between the item and the total item was positive and significant (p < .001). Tiredness was determined as the most common distraction factor, causing errors and making it difficult to achieve goals. CONCLUSIONS The DiSI was found to be a valid and reliable tool. The most common distractions, contributing to errors and obstructing to goals, were related to individuals' skills, performance, and personality. Health care professionals perceived the distractions related to the surgical processes and the situations of the team members in the coordination and situational awareness subdimension as the least distracting factor.

Abstract
Pediatric anesthesia requires the rapid creation, communication, and execution of anesthesia orders, and there is a risk of human error. The authors developed an order-assisted mobile application (app) to reduce human error during pediatric anesthesia preparation. The authors conducted an observational study that compared the effects of the application by comparing anesthesiologists' errors, nurses' errors, nurses leaving the operating room, and delays in surgery, between the Conventional group (n = 101) and the App group (n = 101). The app was associated with reduced human error by anesthesiologists and nurses, and it lowered the frequency and duration of nurses leaving the operating room during anesthesia. In addition, the authors surveyed anesthesia nurses regarding the effectiveness of the app. The nurses confirmed that the app was convenient and reduced human error. This study revealed that the order-assisted mobile app developed by a pediatric anesthesiologist could reduce human errors by anesthesiologists and nurses during pediatric anesthesia preparation.

Abstract
Healthcare relies on high levels of human performance, as described by the 'human as the hero' concept. However, human performance varies and is recognised to fall in high-pressure situations, meaning that it is not a reliable method of ensuring safety. Other safety-critical industries embed human factors principles into all aspects of their organisations to improve safety and reduce reliance on exceptional human performance; there is potential to do the same in anaesthesia. Human factors is a broad-based scientific discipline which aims to make it as easy as possible for workers to do things correctly. The human factors strategies most likely to be effective are those which 'design out' the chance of an error or adverse event occurring. When errors or adverse events do happen, barriers are in place to trap them and reduce the risk of progression to patient and/or worker harm. If errors or adverse events are not trapped by these barriers, mitigations are in place to minimise the consequences. Non-technical skills form an important part of human factors barriers and mitigation strategies and include: situation awareness; decision-making; task management; and team working. Human factors principles are not a substitute for proper investment and appropriate staffing levels. Although applying human factors science has the potential to save money in the long term, its proper implementation may require investment before reward can be reaped. This narrative review describes what is known about human factors in anaesthesia to date.

Abstract
BACKGROUND Anaesthetic procedures are complex and subject to human error. Interventions to alleviate medication errors include organised syringe storage trays, but no standardised methods for drug storage have yet been widely implemented. METHODS We used experimental psychology methods to explore the potential benefits of colour-coded compartmentalised trays compared with conventional trays in a visual search task. We hypothesised that colour-coded compartmentalised trays would reduce search time and improve error detection for both behavioural and eye-movement responses. We recruited 40 volunteers to identify syringe errors presented in pre-loaded trays for 16 trials in total: 12 error present and four error absent, with eight trials presented for each tray type. RESULTS Errors were detected faster when presented in the colour-coded compartmentalised trays than in conventional trays (11.1 s vs 13.0 s, respectively; P=0.026). This finding was replicated for correct responses for error-absent trays (13.3 s vs 17.4 s, respectively; P=0.001) and in the verification time of error-absent trays (13.1 s vs 17.2 s, respectively; P=0.001). On error trials, eye-tracking measures revealed more fixations on the drug error for colour-coded compartmentalised trays (5.3 vs 4.3, respectively; P<0.001), whilst more fixations on the drug lists for conventional trays (8.3 vs 7.1, respectively; P=0.010). On error-absent trials, participants spent longer fixating on the conventional trials (7.2 s vs 5.6 s, respectively; P=0.002). CONCLUSIONS Colour-coded compartmentalisation enhanced visual search efficacy of pre-loaded trays. Reduced fixations and fixation times for the loaded tray were shown for colour-coded compartmentalised trays, indicating a reduction in cognitive load. Overall, colour-coded compartmentalised trays were associated with significant performance improvements when compared with conventional trays.

Abstract
Introduction In demanding work situations (e.g., during a surgery), the processing of complex soundscapes varies over time and can be a burden for medical personnel. Here we study, using mobile electroencephalography (EEG), how humans process workplace-related soundscapes while performing a complex audio-visual-motor task (3D Tetris). Specifically, we wanted to know how the attentional focus changes the processing of the soundscape as a whole. Method Participants played a game of 3D Tetris in which they had to use both hands to control falling blocks. At the same time, participants listened to a complex soundscape, similar to what is found in an operating room (i.e., the sound of machinery, people talking in the background, alarm sounds, and instructions). In this within-subject design, participants had to react to instructions (e.g., "place the next block in the upper left corner") and to sounds depending on the experimental condition, either to a specific alarm sound originating from a fixed location or to a beep sound that originated from varying locations. Attention to the alarm reflected a narrow attentional focus, as it was easy to detect and most of the soundscape could be ignored. Attention to the beep reflected a wide attentional focus, as it required the participants to monitor multiple different sound streams. Results and discussion Results show the robustness of the N1 and P3 event related potential response during this dynamic task with a complex auditory soundscape. Furthermore, we used temporal response functions to study auditory processing to the whole soundscape. This work is a step toward studying workplace-related sound processing in the operating room using mobile EEG.

Abstract
BACKGROUND Operating theatres (OTs) are complex environments where team members complete difficult tasks under stress. Distractions in these environments can lead to errors that compromise patient safety. A range of potential distractions exist in OTs and previous research suggests they are common. This study assesses the nature, frequency and impact of distracting events in the OT at a tertiary New Zealand hospital. METHODS Prospective observational study of the frequency, type and impact of OT distractions during a 3-month period. Two observational methods - the frequency of door openings and a validated tool - were used to categorize OT distractions for a range of acute and elective, paediatric and adult surgical procedures according to their cause and effect. RESULTS There were 57 procedures (2037 intraoperative minutes) observed. During this time, 721 door openings and 1152 other distracting events were recorded. On average, either a door opening or other distracting event was recorded 56 times per hour of intraoperative time. The frequency of distractions did not vary in relation to acute versus elective or paediatric versus adult procedures but were more common in the morning. Communication unrelated to the case was the most common distracting event: these and equipment issues had the greatest effect on the entire surgical team, usually by causing some interruption to operative flow. CONCLUSION Distractions in OTs were common, occurring nearly every minute. Most were trivial, but some had the potential to disrupt the operative procedure and result in patient harm. Reducing distractions in surgery could reduce patient harm and improve resource use.
