RESUMO

This work is directed to an understanding as to how the knowledge of, and the application of human factors and ergonomics (HF/E) can save lives. To achieve this, the paper features an assessment of the achievements of one particular scientist, Neville Anthony Stanton, and how his body of contributions has impacted the realm of ground transportation and, in particular, driver behavior assessment. On the widest scale, it is objectively and obviously the case that Stanton is one of the most fecund scientists of our discipline ever. His impact is evident globally and results not simply from the sum total of his written and published works but through an extensive record of international scientific presentations, mutual investigative collaborations across the globe, and mentoring at all levels of the Academy and beyond. As well as mastering and elucidating the HF/E dimensions of a number of content domains, he has generated vital, and even unique tools and methods through which we can explore and understand the problem space of HF/E. Placing those attainments in context permits us a wider window upon how the discipline itself exerts practical and positive influences across the wide swath of real-world systems.

RESUMO

Head Mounted Display (HMD) based Augmented Reality (AR) is being increasingly used in manufacturing and maintenance. However, limited research has been done to understand user interaction with AR interfaces, which may lead to poor usability, risk of occupational hazards, and low acceptance of AR systems. This paper uses a theoretically-driven approach to interaction design to investigate the impact of different AR modalities in terms of information mode (i.e. video vs. 3D animation) and interaction modality (i.e. hand-gesture vs. voice command) on user performance, workload, eye gaze behaviours, and usability during a maintenance assembly task. The results show that different information modes have distinct impacts compared to paper-based maintenance, in particular, 3D animation led to a 14% improvement over the video instructions in task completion time. Moreover, insights from eye gaze behaviours such as number of fixations and transition between Areas of Interest (AOIs) revealed the differences in attention switching and task comprehension difficulty with the choice of AR modalities. While, subjective user perceptions highlight some ergonomic issues such as misguidance and overreliance, which must be considered and addressed from the joint cognitive systems' (JCSs) perspective and in line with the predictions derived from the Multiple Resources Model.

RESUMO

In this paper, we discuss the ways in which Neville Stanton has challenged himself, his research colleagues, PhD students, the many co-authors and contributors to his publications, and the entire Ergonomics community to determine what it means for there to be 'consistent standards for how [Ergonomics] methods are described and reported.' Only in this way, can it be possible to make claims about whether or not a method in Ergonomics is effective. Given that he is Chartered as both an Occupational Psychologist and an Ergonomist, it is not surprising that he has been concerned with the question of the reliability and validity of Ergonomics methods. In Occupational Psychology, psychometric and personnel selection methods are expected to exhibit acceptable levels of reliability, but this is an expectation which is still somewhat alien to Ergonomics. Neville's work has been instrumental in raising this issue and in providing approaches which can be used to critically evaluate the methods we use. We think that, despite his ground-breaking work, there is still much to do in the Ergonomics community to create the situation for which he has long argued.

RESUMO

The high prevalence of work-related musculoskeletal disorders (WRMSDs) has been a concern in the meat-processing industry, owing to the manual nature of the work and the high upper-limb and neck exposure to movements that can lead to WRMSD. The ability to perform an accurate and fast assessment of WRMSDs remains a challenge in industrial environments. Most assessment methodologies rely on standard survey-based methods, which are time- and labor-intensive. In this paper, we present an application of inertial measurement units (IMUs) to measure human activity, and the use of artificial intelligence and machine learning techniques to perform task classification and ergonomic assessments in workplace settings. We present the results obtained by using simple low-cost IMUs worn on slaughterhouse worker wrists to capture information on their movements. We describe the use of this information to detect the risk factors of the wrists/hands that can lead to WRMSDs. The results indicate that by using low-cost IMU-based sensors on the wrists of slaughterhouse workers, we can accurately classify the sharpness of the knife and predict the worker RULA score.

RESUMO

BACKGROUND: Previous evidence indicated that musculoskeletal disorders (MSDs) are highly prevalent among dentists. However, limited data are available on the prevalence and predictors for cervical and lumbar pain, the two most common subtypes of MSDs reported internationally. AIM AND OBJECTIVE: The aim and objective of this nationwide cross-sectional study was to assess the prevalence and predictors of cervical and lumbar pain among dental interns in Saudi Arabia. MATERIALS AND METHODS: Data were collected using an online survey that was distributed to dental interns who graduated during the 2018-2019 academic year from all dental schools in Saudi Arabia. The survey included questions related to sociodemographic characteristics, symptoms of MSDs, and ergonomic preventive practices. Bivariate and multivariate logistic regression analyses were performed to assess several predictors of cervical and lumbar pain among our sample population. RESULTS: Of the 1,552 eligible interns, 889 (57%) completed the survey (mean age: 24.8 years, 55% female), with 65% enrolled at public universities. The overall prevalence of cervical pain was 41%, and the corresponding prevalence for lumbar pain was 32%. Female participants had significantly higher odds of reporting cervical pain [odds ratio (OR): 2.02, p <0.001]. Participants who typically avoid excessive bending and twisting were significantly less likely to report cervical pain and lumbar pain (OR: 0.51, p <0.001, and 0.46, p <0.0001, respectively). CONCLUSION: Cervical pain and lumbar pain are highly prevalent among Saudi dental interns. Female sex was identified as a potential risk factor for cervical pain, and avoiding bending and twisting during dental work was identified as a protective factor for cervical and lumbar pain. CLINICAL SIGNIFICANCE: Our results indicate that cervical and lumbar pain represent relevant health issues for dental students. Our data add further support to the notion that dental schools should consider enhancing training on dental ergonomics, enabling healthier careers for future dentists in Saudi Arabia.

RESUMO

Objective: To analyze the detection and influencing factors of work-related musculoskeletal disorders (WMSDs) of workers in an automobile manufacturing enterprise in Guangzhou City. Methods: In April 2020, a total of 7065 workers of an automobile manufacturing enterprise in Guangzhou City were selected as research subjects using cluster sampling method. The Nordic Musculoskeletal Questionnaire (NMQ) was used to investigate the detection of WMSDs. Multiple logistic regression analysis was used to analyze the influencing factors of WMSDs. Results: The detection rate of WMSDs was 43.9% (3102/7065) , among which the detection rate of multiple WMSDs was 31.4%. The detection rates of WMSDs in different parts from high to low were as follows: neck (24.5%) , shoulder (21.1%) and ankle (20.1%) . Multivariate logistic regression analysis showed that working experience of 3-8 years, >8 years, age>30 years old, repetitive work every day, multiple repetitions per minute, uncomfortable work posture, frequent overtime work and lack of staff in the department were risk factors for multi-site WMSDs (P<0.05) . Adequate rest time was a protective factor for multi-site WMSDs (P<0.05) . Conclusion: The detection rates of WMSDs in neck, shoulder, ankle, and multisite in automobile manufacturing enterprise are relatively high. The primary risk factors include adverse ergonomic factors and unreasonable organization of labour factors, optimize the work breaks can effectively reduce the risk of disease, effective ergonomic interventions should be carried out to prevent the occurrence of WMSDs among workers in the automobile manufacturing industry.

RESUMO

Studies demonstrate that there is a lack of effective ergonomic principles for adopting a neutral posture during the execution of dental procedures. ISO 11.226:2000 Standard, Corr. 1:2006 has been thoroughly evaluated and adapted to the way that dentists work by the European Society of Dental Ergonomics (ESDE). However, after 15 years, no studies that showed strong evidence of effectiveness in reducing the prevalence of awkward posture in applying its parameters within the scope of dental practice were found. The aim of this study was to verify the effectiveness of applying the ergonomic parameters proposed by the European Society of Dental Ergonomics (ESDE) and ISO 11226 in reducing the prevalence of the main awkward postures adopted by female dental surgeons during the execution of dental scaling on a dental mannequin. A randomized clinical trial was carried out with sixty dental surgeons randomly assigned to two groups: the intervention group, who received instructions and theoretical and practical ergonomic training; and the control group, who received the same training only at the end of the study. For data analysis, Software IBM SPSS 27 and RStudio was used. Descriptive statistics were performed to verify the effectiveness of the intervention, and generalized linear models (specifically, generalized estimated equation models) were used. Poisson distribution was carried out with log link function and network analyses. Sixty female dental surgeons participated in the study. Twenty-two were distributed in the intervention group and thirty-eight in the control group. It was found that ergonomic training enabled a 63% reduction in the prevalence of awkward postures and that there was a statistically significant difference (p < 0.001) only in the intervention group. The analyses showed that the estimated marginal means of postures not recommended in the groups' initial control, final control, initial intervention, and final intervention were 8.6, 8.2, 9.0, and 3.4, respectively. The relationship of networks analyses of the variables is shown with different profiles in the control and intervention groups, but the same pattern between the groups only vary in the strength and direction of the correlations. It was concluded that the ergonomic training based on the parameters of ISO 11226 and DIN EN 1005-4, and its adaptations to the dental practice provided by the European Society of Dental Ergonomics, as well as recent studies, contributed significantly to reducing the prevalence of awkward postures adopted by female dentists during the simulation of the basic periodontal procedures; however, it was not effective enough to improve the posture of the head and neck.

RESUMO

Measuring muscle fatigue is one essential and standard method to quantify the ergonomic risks associated with prolonged low-load exposure. However, measuring muscle fatigue using EMG-based methods has shown conflicting results under low-load but sustained work conditions, e.g., prolonged sitting. Muscle stimulation technology provides an alternative way to estimate muscle fatigue development during such work conditions by monitoring the stimulation-evoked muscle responses, which, however, could be restricted by the accessibility and measurability of targeted muscles. This study proposes a computer vision-based method to overcome such potential restrictions by visually quantifying the muscle belly displacement caused by muscle stimulation. The results demonstrate the ability of the developed computer vision-based stimulation method to detect muscle fatigue from prolonged low-load tasks. Current results can be used as a foundation to develop a sensitive and reliable method to quantify the adverse effects of the daily low-load sustained condition in occupational and nonoccupational settings.

RESUMO

When the inventory is arranged in a dental practice, a distinction can be made between four different dental workplace concepts (DWCs). Since the prevalence of musculoskeletal diseases in dental professionals is very high, preventive solution need to be investigated. As the conventionally used DWCs have, to date, never been studied in terms of their ergonomics, this study aims to investigate the ergonomic risk when working at the four different DWCs. In total, 75 dentists (37 m/38 f) and 75 dental assistants (16 m/59 f) volunteered to take part in this study. Standardized cooperative working procedures were carried out in a laboratory setting and kinematic data were recorded using an inertial motion capture system. The data were applied to an automated version of the Rapid Upper Limb Assessment (RULA). Comparisons between the DWCs and between the dentists and dental assistants were calculated. In all four DWCs, both dentists and dental assistants spent 95-97% of their working time in the worst possible RULA score. In the trunk, DWCs 1 and 2 were slightly favorable for both dentists and dental assistants, while for the neck, DWC 4 showed a lower risk score for dentists. The ergonomic risk was extremely high in all four DWCs, while only slight advantages for distinct body parts were found. The working posture seemed to be determined by the task itself rather than by the different inventory arrangements.

RESUMO

INTRODUCTION: Surgical procedures with loupe magnification, headlights, and microscopes expose craniofacial surgeons to mechanical stress that can increase risk of long-term musculoskeletal pain and injury. Identifying the prevalence and cause of work-related musculoskeletal discomfort may guide preventative strategies to prolong well-being, job satisfaction, and greater duration of surgical careers. METHODS: A 29-question online survey was distributed to the surgeon members of the American Cleft Palate-Craniofacial Association. Eight hundred seventy-three surveys were distributed, and the anonymous responses were recorded using Google forms. RESULTS: One hundred ninety-six unique responses were recorded (22.5% response rate). A total of 64.2% reported experiencing musculoskeletal symptoms during their career, with neck, lower back, and shoulders being the most common problem areas. Multivariate analysis demonstrated surgical loupes (odds ratio 2.36, P = 0.03) and length of surgical practice >15 years (odds ratio 1.95, P = 0.04) were independently associated with greater odds of developing symptoms. Headlights (median pain = 3, P < 0.001), loupes (median pain = 3.5, P < 0.001), and operative microscope use (median pain = 2, P = 0.02) were all associated with higher pain while operating. A total of 52.5% respondents sought medical treatments, 50.5% were concerned musculoskeletal discomfort would affect their careers, 56.6% reported a colleague that required an operation, and 30.2% reported a colleague on temporary or permanent disability. CONCLUSIONS: Craniofacial surgery often involves long procedures, use of surgical adjuncts, and ergonomically straining postures, which can lead to musculoskeletal discomfort and injury. This under-reported and important phenomenon merits candid conversation and active preventative strategies to prolong surgical careers, improve professional satisfaction, and maximize patient safety.

RESUMO

BACKGROUND: The match between classroom furniture and students' anthropometry is an important factor in students' academic performance. OBJECTIVE: Our aim was to investigate the ergonomic suitability of the classroom furniture to the students, and to propose design suggestions for both desks and chairs. METHODS: We analyzed the ergonomics of classroom furniture that students aged 10-14 years old in Turkey currently use. To this end, we selected Maltepe Primary Education School, one of the largest schools in the Çankaya district of Turkey's capital city, Ankara, in which to conduct the study. A sample of 119 students was selected, and seven anthropometric measurements were taken for each of these students. We then calculated five relationships between the dimensions of the furniture and the students' anthropometric measures. RESULTS: We observed high levels of mismatch rates, with an average of 66.6%and high values of over 95%for the relations of two furniture measures, seat depth (related with buttock-popliteal length) and seat-to-desk height (related with elbow height, sitting). Each anthropometric measure was applied a fit probability distribution, and based on those distributions; we suggested the most appropriate classroom furniture dimensions in order to maximize suitability of the furniture to the anthropometric measures in terms of fixed-size (i.e., non-adjustable) classroom furniture. CONCLUSIONS: High mismatch rates can be reduced by 52.0%on average based on the classroom furniture dimensions suggested in this study.

RESUMO

BACKGROUND: In Bangladesh, workers typically spend at least eight hours a day at garment factories in sitting and/or standing position. Prolonged sitting on ergonomically unfit furniture causes back, neck, and shoulder pain, which reduces the working efficiency and leading to low productivity. OBJECTIVE: The aim of this study is to design ergonomically correct furniture for Bangladeshi garment workers considering multivariate analysis on the anthropometric data. METHODS: Twelve anthropometric measures and five furniture dimensions were measured. The sample comprised of 600 volunteer workers from different garment industry. The furniture dimensions were compared with the relevant anthropometric characteristics and found a high level of mismatch (e.g. seat height (male 18%, female 94.25%), seat depth (male 96%, female 63.50%), seat width (male 9.50%, female 36.25%), sewing table height (male 56.50%, female 50%), and desk height for inspection, cutting and ironing table (male 100%, female 100%). RESULTS: New design specifications were proposed of the worker which improved the match percentage. The multivariate anthropometric analysis generated 8 cases and for each case the ranges of anthropometric measurements have been identified. CONCLUSION: The results will help to design robust ergonomic garments furniture.

RESUMO

BACKGROUND: Musculoskeletal disorders are one of the major health hazards among farmers. Pre-adolescents are mainly associated with agricultural work due to poor socioeconomic conditions. OBJECTIVES: This study aims to implement a new ergonomics aid for the betterment of job procedures and improvement of productivity, health, and safety of the preadolescent farmers. METHODS: 100 male and 100 female preadolescent farmers were randomly selected from the villages of Tarakeswar, West Bengal, India, to evaluate and reduce work-related musculoskeletal disorders, physiological stress. Modified Nordic questionnaires, Body Part Discomfort (BPD) scale, and handgrip strength were assessed before and after using the ergonomics aid. RESULTS: The results of the study show that there was a significant change (decrease) in discomfort in the lower back, wrists, shoulder, and hands among preadolescent farmers when using the newly designed ergonomic aid. Handgrip strength increased and physiological stress was decreased among preadolescent farmers in post-intervention than pre-intervention in just after work conditions. Productivity has been increased in farming by decreasing absenteeism from work with the use of ergonomic aid. CONCLUSION: This study concludes that productivity has been increased in farming by decreasing absenteeism from work as well as by using the ergonomic aid the discomfort feeling has been decreased markedly.

RESUMO

The aim of the presented work is to analyze the ergonomics-related disorders in online education using the fuzzy AHP approach. A group dialogue with online education academicians, online education students, biotechnologists, and sedentary computer users has been performed to spot ergonomics-related disorders in online education. Totally eight ergonomics-related disorders in online education have been identified, and the weight of each disorder has been computed with triangle-shaped fuzzy numbers in pairwise comparison. Furthermore, the ergonomics-related disorders in online education are kept in four major categories such as afflictive disorders, specific disorders, psychosocial disorders, and chronic disorders. These four categories of ergonomics-related disorders in online education are evaluated and compared using fuzzy analytical hierarchical process methodology to get ranked in terms of priorities. The results may be instrumental for taking appropriate corrective actions to prevent ergonomics-related disorders.

RESUMO

Musculoskeletal disorder (MSD) is already prevalent in dental students despite their young age and the short duration of dental practice. The current findings state that the causes of MSD are related to posture during dental work. This study aims to investigate the ergonomic risk of dental students. In order to analyze the ergonomic risk of dental students, 3D motion analyses were performed with inertial sensors during the performance of standardized dental activities. For this purpose, 15 dental students and 15 dental assistant trainees (all right-handed) were measured in a team. Data were analyzed using the Rapid Upper Limb Assessment (RULA), which was modified to evaluate objective data. Ergonomic risk was found for the following body parts in descending order: left wrist, right wrist, neck, trunk, left lower arm, right lower arm, right upper arm, left upper arm. All relevant body parts, taken together, exhibited a posture with the highest RULA score that could be achieved (median Final Overall = 7), with body parts in the very highest RULA score of 7 for almost 80% of the treatment time. Dental students work with poor posture over a long period of time, exposing them to high ergonomic risk. Therefore, it seems necessary that more attention should be paid to theoretical and practical ergonomics in dental school.

RESUMO

BACKGROUND: Many organizational interventions aim to improve working conditions to promote and protect worker safety, health, and well-being. The Workplace Organizational Health Study used process evaluation to examine factors influencing implementation of an organizational intervention. This paper examines the extent to which the intervention was implemented as planned, the dose of intervention implemented, and ways the organizational context hindered or facilitated the implementation of the intervention. METHODS: This proof-of-concept trial was conducted with a large, multinational company that provides food service through contractual arrangements with corporate clients. The 13-month intervention was launched in five intervention sites in October 2018. We report findings on intervention implementation based on process tracking and qualitative data. Qualitative data from 25 post-intervention interviews and 89 process tracking documents were coded and thematically analyzed. RESULTS: Over the 13-month intervention, research team representatives met with site managers monthly to provide consultation and technical assistance on safety and ergonomics, work intensity, and job enrichment. Approximately two-thirds of the planned in-person or phone contacts occurred. We tailored the intervention to each site as we learned more about context, work demands, and relationships. The research team additionally met regularly with senior leadership and district managers, who provided corporate resources and guidance. By assessing the context of the food service setting in which the intervention was situated, we explored factors hindering and facilitating the implementation of the intervention. The financial pressures, competing priorities and the fast-paced work environment placed constraints on site managers' availability and limited the full implementation of the intervention. CONCLUSIONS: Despite strong support from corporate senior leadership, we encountered barriers in the implementation of the planned intervention at the worksite and district levels. These included financial demands that drove work intensity; turnover of site and district managers disrupting continuity in the implementation of the intervention; and staffing constraints that further increased the work load and pace. Findings underscore the need for ongoing commitment and support from both the parent employer and the host client. TRIAL REGISTRATION: This study was retrospectively registered with the Clinical Trials. Gov Protocol and Results System on June 2, 2021 with assigned registration number NCT04913168 .

RESUMO

OBJECTIVE: Human factors and ergonomics (HF/E) frameworks and methods are becoming embedded in the health informatics community. There is now broad recognition that health informatics tools must account for the diverse needs, characteristics, and abilities of end users, as well as their context of use. The objective of this review is to synthesize the current nature and scope of HF/E integration into the health informatics community. METHODS: Because the focus of this synthesis is on understanding the current integration of the HF/E and health informatics research communities, we manually reviewed all manuscripts published in primary HF/E and health informatics journals during 2020. RESULTS: HF/E-focused health informatics studies included in this synthesis focused heavily on EHR customizations, specifically clinical decision support customizations and customized data displays, and on mobile health innovations. While HF/E methods aimed to jointly improve end user safety, performance, and satisfaction, most HF/E-focused health informatics studies measured only end user satisfaction. CONCLUSION: HF/E-focused health informatics researchers need to identify and communicate methodological standards specific to health informatics, to better synthesize findings across resource intensive HF/E-focused health informatics studies. Important gaps in the HF/E design and evaluation process should be addressed in future work, including support for technology development platforms and training programs so that health informatics designers are as diverse as end users.

RESUMO

BACKGROUND: Musculoskeletal disorders are common worldwide. Several factors are suggested in their aetiology, one of which is ergonomics alongside other individual factors. This study aims at investigating the prevalence of musculoskeletal disorders among administrative office workers at a large university in Saudi Arabia. METHODS: This cross-sectional study recruited office workers at a Saudi university. A questionnaire was used that involved three sections, the first section consisted of sociodemographic questions, the second included the Rapid Office Strain Assessment (ROSA) checklist to assess ergonomic factors possibly involved, and the third included the Nordic Musculoskeletal Questionnaire to measure the outcome. Bi-variate analyses were performed by Chi-Squared tests and T-tests where appropriate, and a multivariable logistic regression was done to yield odds ratios (OR) and 95% confidence intervals (CIs). RESULTS: The prevalence of musculoskeletal symptoms in any region during the past 12 months preceding the study was 84.5%, and only 30% have sought medical advice. The most common area of complaint was the lower back (54.5%). After adjustment, age and years of experience were positively associated with musculoskeletal symptoms (OR = 1.04, 95% CI = 1.01-1.09 and OR = 1.10, 95% CI = 1.05-1.15). Normal weight was associated with a significant reduction in risk (OR = 0.10, 95% CI = 0.05-0.18). ROSA score was an independent risk factor (OR = 1.77, 95% CI = 1.05-2.96). CONCLUSIONS: Musculoskeletal symptoms were highly prevalent in the current sample. Identified predictors may support the need for interventions to reduce risk.

RESUMO

Total Worker Health® (TWH) interventions that utilize integrated approaches to advance worker safety, health, and well-being can be challenging to design and implement in practice. This may be especially true for the food service industry, characterized by high levels of injury and turnover. This paper illustrates how we used TWH Implementation Guidelines to develop and implement an organizational intervention to improve pain, injury, and well-being among low-wage food service workers. We used the Guidelines to develop the intervention in two main ways: first, we used the six key characteristics of an integrated approach (leadership commitment; participation; positive working conditions; collaborative strategies; adherence; data-driven change) to create the foundation of the intervention; second, we used the four stages to guide integrated intervention planning. For each stage (engaging collaborators; planning; implementing; evaluating for improvement), the Guidelines provided a flexible and iterative process to plan the intervention to improve safety and ergonomics, work intensity, and job enrichment. This paper provides a real-world example of how the Guidelines can be used to develop a complex TWH intervention for food service workers that is responsive to organizational context and addresses targeted working conditions. Application of the Guidelines is likely transferable to other industries.

BACKGROUND: This study aims to present two system models widely used in Human Factors and Ergonomics (HF/E) and evaluate whether the models are adoptable to England's national patient safety team in improving the exploration and understanding of multiple incident reports of an active patient safety issue and the development of the remedial actions for a potential National Patient Safety Alert. The existing process of examining multiple incidents is based on inductive thematic analysis and forming the remedial actions is based on barrier analysis of intelligence on potential solutions. However, no formal systems models evaluated in this study have been used. METHODS: AcciMap and Systems Engineering Initiative for Patient Safety (SEIPS) were selected, applied and evaluated to the analysis of two different sets of patient safety incidents: (i) incidents concerning ingestion of superabsorbent polymer granules and (ii) incidents concerning the interruption in use of High Nasal Flow Oxygen. The first set was analysed by the first author and the utility and usability were reflected. The second set was analysed collectively by a purposeful sample of patient safety team members, who create the National Patient Safety Alerts from incident-level data and information. All of them attended a 30-min video-based training and a 1.5 h case-based online workshop. Post-workshop individual interviews were conducted to evaluate their perceived utility and usability of each model. RESULTS: The patient safety team showed overwhelming support for the utility of the system models as a 'framework' that provides a systematic, structured way of looking at an issue and examining the causes, whilst also sharing concerns regarding their usability. AcciMap was viewed useful particularly in providing a visual comprehensive overview of the issue but considered chaotic by some participants due to many arrows between factors. SEIPS was perceived easier to understand due to the familiarity of the structure (Donbedian's model), but the non-hierarchical format of SEIPS was considered less useful. CONCLUSIONS: The participants of the study agreed with the high level of utility of both models for their unique strengths, but shared some concern for the usability of them in terms of complexity and further training/coaching time would be required to adopt these models in their daily practices. It is recommended that the gap between HF/E practitioners and patient safety practitioners can be narrowed by strengthening education, and coaching and mentoring relationships between the two groups, led by the increasing number of healthcare practitioners who embrace their membership to HF/E practice.
