Publication Exploring Voice Barriers And Subsequent Practices Among Frontline Healthcare Workers In Pakistan: A Comprehensive Mixed-methods Analysis(Springer Nature, 2025) ;Noreen Kanwal ;Ahmad Shahrul Nizam Isha ;Al-baraa Abdulrahman Al-MekhlafRao Irfan Ali HaiderBackground Voice barriers among frontline healthcare workers hinder safety related to work and patients. Understanding these barriers and practices is crucial to improve voice behavior in healthcare settings. Therefore, this study aims to identify the voice barriers and practices among healthcare workers in Pakistan. Research method The study has adopted a mixed-method research design. Data was collected from 15 frontline healthcare workers through semi-structured interviews to achieve study objectives. Descriptives and content analysis were conducted to explore voice barriers and alternative practices to solve their concerns. After that, a quantitative study was conducted to determine the statistical significance of the identified voice barriers and the magnitude of their effect. For this purpose, data was collected from 480 frontline healthcare workers in the primary, secondary, and territory healthcare units. A questionnaire survey was used for data collection. Then, multistage hierarchical regression analysis was employed for data analysis. Results Study findings highlight the determinants of two key factors: withholding patient safety concerns and withholding worker safety concerns. First, the study identifies several factors that increase the likelihood of healthcare workers withholding concerns about patient safety. These factors include professional designation, work experience, blackmailing, overconfidence, longer work tenure, feelings of insult, early career stage, fear of patient reactions, bad past experiences, job insecurity, and uncooperative management. Fear of increased workload also plays a significant role. Second, when it comes to work-related safety concerns, factors such as gender, shyness, lack of confidence, fear of duty changes, management issues, interpersonal conflicts, and resource shortages contribute to the withholding of concerns. To navigate these challenges, healthcare workers often resort to strategies such as seeking political connections, personal settlements, transfers, union protests, quitting, using social media, engaging in private practice, or referring patients to other hospitals. Conclusion Findings demonstrates that healthcare workers in Pakistan often withhold safety concerns due to hierarchical pressures, personal insecurities, and fear of repercussions. Their reliance on external mechanisms, such as political influence or social media, underscores the need for significant reforms to improve safety culture and management support. Addressing these issues is crucial for ensuring both patient and worker safety. - Some of the metrics are blocked by yourconsent settings
Publication Implementation of a Psychomotor Vigilance Test to Investigate the Effects of Driving Fatigue on Oil and Gas Truck Drivers’ Performance(Frontiers, 2023) ;Al-Baraa Abdulrahman Al-Mekhlafi ;Ahmad Shahrul Nizam Isha ;Maged S. Al-QuraishiNoreen KanwalIntroduction: Driving fatigue has been shown to increase the risk of accidents and potentially fatal crashes. Fatigue is a serious risk that some drivers do not take seriously. Previous studies investigated the effects of driving fatigue in the Malaysian oil and gas transportation industry by employing survey questionnaires. However, they did not explain the behavior of fatigue. Besides, these results required validation by a more reliable method that can describe how fatigue occurs. Methods: Thus, in this study, we used the Psychomotor Vigilance Test (PVT-192) and a short survey to address driving fatigue behavior and identify the influences of driving fatigue on driving performance in real life (on the road) with actual oil and gas tanker drivers. The total participants in the experimental study were 58 drivers. Results: For the analysis, a Wilcoxon Signed Ranks Test, Z value and Spearman’s rho were used to measure the significant difference between the pre and post-tests of PVT and the correlation between the fatigue variables and driving performance. Discussion: During the experiment’s first and second days, this study’s results indicated that driving fatigue gradually escalated. Likewise, there was a negative correlation based on the test of the relationship between the PVT data and the driving performance survey data. Additionally, the drivers suffer from accumulative fatigue, which requires more effort from the transportation company management to promote the drivers awareness of fatigue consequences.7 23 - Some of the metrics are blocked by yourconsent settings

These results highlight the substantial contribution of the work environment to driving performance, with an effect of 63%. Consequently, the study emphasizes the importance of considering the work environment as a potential factor when assessing and enhancing tanker drivers’ driving abilities during oil and gas transportation. - Some of the metrics are blocked by yourconsent settings
Publication Risk Assessment of Driver Performance in the Oil and Gas Transportation Industry: Analyzing the Relationship Between Driver Vigilance, Attention, Reaction Time, and Safe Driving Practices(Cell press in collaboration with Elsevier, 2024) ;Al-Baraa Abdulrahman Al-Mekhlafi ;Ahmad Shahrul Nizam Isha ;Nicholas Chileshe ;Ahmed Farouk Kineber ;Muhammad Ajmal ;Abdullah O. BaarimahAl-Hussein M.H. Al-AidrousThe increasing use of road traffic for land transportation has resulted in numerous road accidents and casualties, including those involving oil and gas tanker vehicles. Despite this, little empirical research has been conducted on the factors influencing tanker drivers' performance. This study aims to address this knowledge gap, particularly in the energy transportation industry, by examining the driving performance factors that affect tanker drivers and incorporating risk assessment measures. The model variables were identified from the literature and used to develop a survey questionnaire for the study. A total of 307 surveys were collected from Malaysian oil and gas tanker drivers, and the driving performance factors were contextually adjusted using the Exploratory Factor Analysis (EFA) approach. The driving performance model was developed using partial least squares structural equation modeling (PLS-SEM). The EFA results categorized driving performance into two constructs: 1) drivers' reaction time with β = 0.320 and 2) attention and vigilance with β value = 0.749. The proposed model provided full insight into how drivers’ reaction time, attention, and vigilance impact drivers' performance in this sector, which can help identify potential risks and prevent accidents. The findings are significant in understanding the factors that affect oil and gas drivers' performance and can aid in enhancing oil and gas transportation management by including effective risk assessment measures to prevent fatal crashes.7 29 - Some of the metrics are blocked by yourconsent settings
