Distractions in the Anesthesia Work Environment: Impact on Patient Safety? Report of a Meeting Sponsored by the Anesthesia Patient Safety Foundation

The use of smart glasses in nursing education: A scoping review

AIM

The aim of this scoping review was to give an overview of the usability and feasibility of smart glasses in nursing education. In addition, this study will highlight nursing students' experiences of using smart glasses in learning situations.

BACKGROUND

Healthcare is becoming increasingly complex and technological and so is nursing education. Technology enhanced learning aims to enhance the teaching-learning process through use of technology, for example through smart glasses.

DESIGN AND METHODS

A literature review using a scoping review methodology was conducted. Qualitative content analysis was performed to analyse data. 14 references were included in the analysis. References were found using the databases PubMed, SCOPUS and ERIC.

RESULTS

The analysis resulted in three categories; (1) Situations in which smart glasses have been used in nursing education, (2) Learning experiences from using smart glasses in nursing education, and (3) User experiences from using smart glasses in nursing education. Smart glasses were used in different learning situations and were in general positively evaluated by nursing students. Although, drawbacks of using smart glasses were noted which could negatively effect student learning.

CONCLUSIONS

Smart glasses have been used in a variety of learning situations in nursing education and enabled new learning situations. Students found smart glasses beneficial for their learning and smart glasses motivated and engaged students in the learning situation. Although, this was both user- and situation dependent. Technical issues could cause students to lose focus and there is need for technical support to facilitate the learning curve. By learning from others' experiences unnecessary drawbacks can be avoided.

Physicians' perceptions of two ways of algorithm presentation: graphic versus text-based approach

Acute bleeding during surgery or after trauma harms patients, and challenges involved physicians. Protocols and cognitive aids can help in such situations. This dual-centre study investigated physicians' opinions regarding two ways to present cognitive aids, graphic 'Haemostasis Traffic Light' and text-based, using the example of a coagulation management algorithm to identify the strengths and limitations of both presentation modalities. Using qualitative research methods, we identified recurring answer patterns and derived major topics and subthemes through inductive coding. Eighty-four physicians participated. We assigned each half randomly to one of the cognitive aids (graphic/text-based) and determined 447 usable statements. We qualitatively deduced the importance of having a cognitive aid for physicians. Furthermore, it is noticeable that the graphic group made more positive comments (154 of 242 (64%) statements), while the text-based participants made more negative annotations (126 of 205 (61%) statements), suggesting a generally stronger approval of this cognitive aid. Practitioner summary: This qualitative study provides an overview of physicians` positive and negative perceptions regarding two presentation ways for a coagulation management algorithm. Participants perceived the graphic method created according to user-centred design principles more positively. The analysis reveals components that an ideal algorithm should have to help streamline the decision-making process.

Nurse anesthetists' experiences using smart glasses to monitor patients' vital signs during anesthesia care: A qualitative study

PURPOSE

To describe nurse anesthetists' experiences using smart glasses to monitor patients' vital signs during anesthesia care.

METHODS

Data was collected through individual semi-structured interviews with seven nurse anesthetists who had used smart glasses, with a customized application for monitoring vital signs, during clinical anesthesia care. Data was analyzed using thematic content analysis.

RESULTS

An overarching theme became evident during analysis; Facing and embracing responsibility. Being a nurse anesthetist entails a great responsibility, and the participants demonstrated that they shouldered this responsibility with pride. The theme was divided in two sub-themes. The first of these, A new way of working, comprised the categories Adoption and Utility. This involved incorporating smart glasses into existing routines in order to provide safe anesthesia care. The second sub-theme, Encountering side effects, consisted of the categories Obstacles and Personal affect. This sub-theme concerned the possibility to use smart glasses as intended, as well as the affect on nurse anesthetists as users.

CONCLUSION

Smart glasses improved access to vital signs and enabled continuous monitoring regardless of location. Continued development and improvement, both in terms of the application software and the hardware, are necessary for smart glasses to meet nurse anesthetists' needs in clinical practice.

The Effect of Noise Levels in the Operating Room on the Stress Levels and Workload of the Operating Room Team

PURPOSE

The research was conducted to evaluate the noise levels and the effect of noise on the workload and stress levels of the operating room (OR) staff of a public hospital.

DESIGN

Descriptive and cross-sectional study.

METHODS

The data were obtained by measuring ambient noise during 403 orthopaedic, urological, and general surgeries on weekdays between July and October 2019. We measured the noise by dividing the surgery into three phases. These phases are as follows: from the entry of the patient, induction of anesthesia, and preparation of the surgical area until the start of the procedure (Phase I), from the incision until the completion of closure and dressing application (Phase II), from the completion of closure and dressing application until the exit of the patient (Phase III). Furthermore, the workload and stress levels of 45 OR staff who work in the general surgery, orthopaedics, and urology ORs were measured. Data were collected using a CA 834 noise measurement device, State-Trait Anxiety Inventory (STAI Form TX-I), the National Aeronautics and Space Administration (NASA) Task Load Index Workload Scale, and Information form related to surgery and ORs.

FINDINGS

The noise in the OR was higher than 35 dB, A-weighted [dB(A)], the limit proposed by the World Health Organization for hospitals. Phase I average noise level was 63.00 ± 3.50, Phase II average noise level was 62.94 ± 3.75, and Phase III average noise level was 63.67 ± 2.81. The mean anxiety score was 34.50 ± 6.09. The total workload level was found to be 56.91 ± 15.67. Anxiety scores and workload scores had positive weak and moderate correlations with noise levels (P < .01).

CONCLUSIONS

The noise in the OR was high, and anxiety scores and workload scores correlated positively with noise levels.

Distraction in the operating room: A narrative review of environmental and self-initiated distractions and their effect on anesthesia providers

The operating room (OR) is a busy environment with multiple opportunities for distraction. A well-trained anesthesiologist or certified registered nurse anesthetist (CRNA) should remain focused on providing excellent patient care despite these potential distractions. The purpose of this narrative review is to present the multiple types of OR distractions and evaluate each for their level of distraction and their likely impact on patient safety. Distractions in the OR are common and numerous types of distractions exist. Loud OR background noise can lead to miscommunication within the OR team. In several studies, OR noise has been shown to decrease vigilance and possibly delay recognition of non-routine events. The most commonly observed distracting events are "small talk" and staff entering and exiting the OR and most intense distracting events are faulty or unavailable equipment. Phone and pager use can be particularly distracting. Self-initiated distractions can be seen as unprofessional and can negatively impact patient safety. The impact of OR distractions on patient outcomes deserves more vigorous investigation. We must provide anesthesia trainees with the skills to remain vigilant despite numerous and varied OR distractions while also attempting to reduce such OR distractions to improve patient safety. Further research is needed to inform the institution of policies to lessen unnecessary OR distractions.

Smart Glasses for Anesthesia Care: Initial Focus Group Interviews with Specialized Health Care Professionals

PURPOSE

Smart glasses are a kind of wearable technology that gives users sustained, hands-free access to data and can transmit and receive information wirelessly. Earlier studies have suggested that smart glasses have the potential to improve patient safety in anesthesia care. Research regarding health care professionals' views of the potential use of smart glasses in anesthesia care is limited. The purpose of this study was to describe anesthesia health care professionals' views of smart glasses before clinical use.

DESIGN

A qualitative descriptive study.

METHODS

Data were collected from focus group interviews and analyzed using thematic content analysis.

FINDINGS

Three categories of participants' views of smart glasses were created during the analysis: views of integrating smart glasses in clinical setting; views of customized functionality of smart glasses; and views of being a user of smart glasses. One theme, striving for situational control, was identified in the analysis.

CONCLUSIONS

Smart glasses were seen as a tool that can impact and improve access to patient-related information, and aid health care professionals in their struggle to gain situational control during anesthesia care. These are factors related to increased patient safety.

Situation Awareness-Oriented Patient Monitoring with Visual Patient Technology: A Qualitative Review of the Primary Research

Visual Patient technology is a situation awareness-oriented visualization technology that translates numerical and waveform patient monitoring data into a new user-centered visual language. Vital sign values are converted into colors, shapes, and rhythmic movements-a language humans can easily perceive and interpret-on a patient avatar model in real time. In this review, we summarize the current state of the research on the Visual Patient, including the technology, its history, and its scientific context. We also provide a summary of our primary research and a brief overview of research work on similar user-centered visualizations in medicine. In several computer-based studies under various experimental conditions, Visual Patient transferred more information per unit time, increased perceived diagnostic certainty, and lowered perceived workload. Eye tracking showed the technology worked because of the way it synthesizes and transforms vital sign information into new and logical forms corresponding to the real phenomena. The technology could be particularly useful for improving situation awareness in settings with high cognitive demand or when users must make quick decisions. This comprehensive review of Visual Patient research is the foundation for an evaluation of the technology in clinical applications, starting with a high-fidelity simulation study in early 2020.

Noise as a risk factor in the delivery room: A clinical study

Introduction

We aimed to investigate whether noise in delivery rooms is associated with impaired performance of obstetric teams managing major (≥1000 mL) postpartum hemorrhage.

Material and methods

We included video recordings of 96 obstetric teams managing real-life major postpartum hemorrhage. Exposure was noise defined as the occurrence of sound level pressures (SPL) above 90 dB. The outcome was high clinical performance assessed through expert ratings using the TeamOBS-PPH tool.

Results

The 23 teams unexposed to noise had a significantly higher chance of high clinical performance than the 73 teams exposed to noise: 91.3% (95% CI; 72.0–98.9) versus 58.9% (95% CI; 46.8–70.3) (p < 0.001). The results remained significant when adjusting for the following possible confounders: team size, non-technical performance, bleeding velocity, hospital type, etiology of bleeding, event duration and time of day. Typical sources of noise above 90 dB SPL were mother or baby crying, dropping of instruments, and slamming of cupboard doors.

Conclusion

Noise in delivery rooms may be an independent source of impaired clinical performance.

Prevalence of Potentially Distracting Noncare Activities and Their Effects on Vigilance, Workload, and Nonroutine Events during Anesthesia Care

Background

When workload is low, anesthesia providers may perform non–patient care activities of a clinical, educational, or personal nature. Data are limited on the incidence or impact of distractions on actual care. We examined the prevalence of self-initiated nonclinical distractions and their effects on anesthesia workload, vigilance, and the occurrence of nonroutine events.

Methods

In 319 qualifying cases in an academic medical center using a Web-based electronic medical chart, a trained observer recorded video and performed behavioral task analysis. Participant workload and response to a vigilance (alarm) light were randomly measured. Postoperatively, participants were interviewed to elicit possible nonroutine events. Two anesthesiologists reviewed each event to evaluate their association with distractions.

Results

At least one self-initiated distraction was observed in 171 cases (54%), largely during maintenance. Distractions accounted for 2% of case time and lasted 2.3 s (median). The most common distraction was personal internet use. Distractions were more common in longer cases but were not affected by case type or American Society of Anesthesiologists physical status. Workload ratings were significantly lower during distraction-containing case periods and vigilance latencies were significantly longer in cases without any distractions. Three distractions were temporally associated with, but did not cause, events.

Conclusions

Both nurse anesthetists and residents performed potentially distracting tasks of a personal and/or educational nature in a majority of cases. Self-initiated distractions were rarely associated with events. This study suggests that anesthesia professionals using sound judgment can self-manage nonclinical activities. Future efforts should focus on eliminating more cognitively absorbing and less escapable distractions, as well as training in distraction management.
