Application of Eye Tracking Technology in Aviation, Maritime, and Construction Industries: A Systematic Review.

Most accidents in the aviation, maritime, and construction industries are caused by human error, which can be traced back to impaired mental performance and attention failure. In 1596, Du Laurens, a French anatomist and medical scientist, said that the eyes are the windows of the mind. Eye tracking research dates back almost 150 years and it has been widely used in different fields for several purposes. Overall, eye tracking technologies provide the means to capture in real time a variety of eye movements that reflect different human cognitive, emotional, and physiological states, which can be used to gain a wider understanding of the human mind in different scenarios. This systematic literature review explored the different applications of eye tracking research in three high-risk industries, namely aviation, maritime, and construction. The results of this research uncovered the demographic distribution and applications of eye tracking research, as well as the different technologies that have been integrated to study the visual, cognitive, and attentional aspects of human mental performance. Moreover, different research gaps and potential future research directions were highlighted in relation to the usage of additional technologies to support, validate, and enhance eye tracking research to better understand human mental performance.

Effects of a Brief Team Training Program on Surgical Teams' Nontechnical Skills: An Interrupted Time-Series Study.

BACKGROUND: Up to 60% of adverse events in surgery are the result of poor communication and teamwork. Nontechnical skills in surgery (NOTSS) are critical to the success of surgery and patient safety. The study aim was to evaluate the effect of a brief team training intervention on teams' observed NOTSS. METHODS: Pretest-posttest interrupted time-series design with statistical process control analysis was used to detect longitudinal changes in teams' NOTSS. We evaluated NOTSS using the revised NOTECHS weekly for 20 to 25 weeks before and after implementation of a team training program. RESULTS: We observed 179 surgical procedures with cardiac, vascular, upper gastrointestinal, and hepatobiliary teams. Mean posttest NOTECHS scores increased across teams, showing special cause variation. There were also significant before and after improvements in NOTECHS scores in respect to professional role and in the use of the Surgical Safety Checklist. CONCLUSIONS: Our results suggest associated improvements in teams' NOTSS after implementation of the team training program.

Ambient Intelligence to Improve Construction Site Safety: Case of High-Rise Building in Thailand.

The relatively high rate of injuries in construction is not surprising, as site work by its very nature ranks highly on fundamental risk factors. Working at heights often magnifies these risk factors. The literature reveals that falls from heights accounts for a large percentage of injuries in construction worldwide. Thailand is no exception, where fall accidents constitute the majority of high-rise construction accidents despite preventive measures being implemented. This paper examines how the use of a simple Ambient Intelligence (AmI) system-a device comprising a microcontroller, microwave sensors, Light Emitting Diode (LED) and audio alarm-could help to affect safety behavioural change of on-site construction workers in order to decrease the potential for fall accidents. An experiment was conducted at a high-rise building construction site in Bangkok, Thailand to examine the effectiveness of the AmI in helping workers mitigate the risk of falling from heights. The analysis of the data collected over two work weeks from the pre- and post-AmI application using X-bar charts and one-way analysis of variance (ANOVA) revealed a significant reduction of about 78% in the number of workers passing through the fall hazard zones. The finding established the potential of a simple AmI for reducing the risk of fall accidents.

Influence of safety motivation and climate on safety behaviour and outcomes: evidence from the Saudi Arabian construction industry.

PURPOSE: Over the last three decades, safety literature has focused on safety climate and its role in forecasting injuries and accidents. However, research findings regarding the relationships between safety climate and other key outcome constructs are somewhat inconsistent. Recent safety climate literature suggests that examining the role of safety motivation may help provide a better explanation of such relationships. The research presented in this article aimed to empirically analyse the relationships among safety motivation, safety climate, safety behaviour and safety outcomes within the context of the Saudi Arabian construction industry. METHOD: A conceptual model was developed to examine the relationships among four main constructs: safety motivation, safety climate, safety behaviour and safety outcomes. Based on the survey data collected in Saudi Arabia from site engineers and project managers (n = 295), statistical analyses were carried out, including confirmatory and exploratory factor analysis, and structural equation modelling to assess the model and test the hypotheses. RESULTS: The main results indicated that safety motivation could positively influence safety behaviour through safety climate, which plays a mediating role for this mechanism. The results also confirmed that safety behaviour could predict safety outcomes within the context of the Saudi Arabian construction industry.

Determining the causal relationships among balanced scorecard perspectives on school safety performance: case of Saudi Arabia.

In the public schools of many developing countries, numerous accidents and incidents occur because of poor safety regulations and management systems. To improve the educational environment in Saudi Arabia, the Ministry of Education seeks novel approaches to measure school safety performance in order to decrease incidents and accidents. The main objective of this research was to develop a systematic approach for measuring Saudi school safety performance using the balanced scorecard framework philosophy. The evolved third generation balanced scorecard framework is considered to be a suitable and robust framework that captures the system-wide leading and lagging indicators of business performance. The balanced scorecard architecture is ideal for adaptation to complex areas such as safety management where a holistic system evaluation is more effective than traditional compartmentalised approaches. In developing the safety performance balanced scorecard for Saudi schools, the conceptual framework was first developed and peer-reviewed by eighteen Saudi education experts. Next, 200 participants, including teachers, school executives, and Ministry of Education officers, were recruited to rate both the importance and the performance of 79 measurement items used in the framework. Exploratory factor analysis, followed by the confirmatory partial least squares method, was then conducted in order to operationalise the safety performance balanced scorecard, which encapsulates the following five salient perspectives: safety management and leadership; safety learning and training; safety policy, procedures and processes; workforce safety culture; and safety performance. Partial least squares based structural equation modelling was then conducted to reveal five significant relationships between perspectives, namely, safety management and leadership had a significant effect on safety learning and training and safety policy, procedures and processes, both safety learning and training and safety policy, procedures and processes had significant effects on workforce safety culture, and workforce safety culture had a significant effect on safety performance.

Redesigning the ICU nursing discharge process: a quality improvement study.

PURPOSE: To evaluate the impact of a redesigned intensive care unit (ICU) nursing discharge process on ICU discharge delay, hospital mortality, and ICU readmission within 72 hours. METHODS: A quality improvement study using a time series design and statistical process control analysis was conducted in one Australian general ICU. The primary outcome measure was hours of discharge delay per patient discharged alive per month, measured for 15 months prior to, and for 12 months after the redesigned process was implemented. The redesign process included appointing a change agent to facilitate process improvement, developing a patient handover sheet, requesting ward staff to nominate an estimated transfer time, and designing a daily ICU discharge alert sheet that included an expected date of discharge. RESULTS: A total of 1,787 ICU discharges were included in this study, 1,001 in the 15 months before and 786 in the 12 months after the implementation of the new discharge processes. There was no difference in in-hospital mortality after discharge from ICU or ICU readmission within 72 hours during the study period. However, process improvement was demonstrated by a reduction in the average patient discharge delay time of 3.2 hours (from 4.6 hour baseline to 1.0 hours post-intervention). CONCLUSIONS: Involving both ward and ICU staff in the redesign process may have contributed to a shared situational awareness of the problems, which led to more timely and effective ICU discharge processes. The use of a change agent, whose ongoing role involved follow-up of patients discharged from ICU, may have helped to embed the new process into practice.

Quantifying the influence of environmental and water conservation attitudes on household end use water consumption.

Within the research field of urban water demand management, understanding the link between environmental and water conservation attitudes and observed end use water consumption has been limited. Through a mixed method research design incorporating field-based smart metering technology and questionnaire surveys, this paper reveals the relationship between environmental and water conservation attitudes and a domestic water end use break down for 132 detached households located in Gold Coast city, Australia. Using confirmatory factor analysis, attitudinal factors were developed and refined; households were then categorised based on these factors through cluster analysis technique. Results indicated that residents with very positive environmental and water conservation attitudes consumed significantly less water in total and across the behaviourally influenced end uses of shower, clothes washer, irrigation and tap, than those with moderately positive attitudinal concern. The paper concluded with implications for urban water demand management planning, policy and practice.

Transforming care strategies and nursing-sensitive patient outcomes.

AIM: This paper is a report of the effects of implementing 13 Transforming Care At the Bedside improvement strategies on medication errors, patient falls and pressure ulcers. BACKGROUND: A number of international reports and research studies have led to a focus on safety and quality in health care. Transforming Care At the Bedside involves nursing managers and front-line staff together contributing to practice improvement. METHOD: An observational, time series study in two medical units in one Australian hospital was conducted. Statistical process control analysis was used to identify changes in the outcomes. Routinely collected, anonymous clinical incident reports were used to calculate the proportion of reported clinical incidents that were reported to result in patient harm in the 15 months prior to and 18 months after Transforming Care At the Bedside strategies were implemented, between February, 2005 and December, 2007. RESULTS: The proportion of reported medication errors, falls and pressure ulcers that resulted in harm as reported in clinical incident reports were reduced from 46.3% to 17.1%, 97.0% to 51.0% and 91.3% to 46.6% respectively, representing an absolute reduction by about one half. Consistent, sustained improvement in the first two was demonstrated, but analysis showed wide variation in the third--pressure ulcers--which meant that the differences in this outcome may have occurred by chance. CONCLUSION: A rapid change management cycle such as Transforming Care At the Bedside can be a useful process when implementing numerous clinical changes in short succession.
