RESUMEN

The novel coronavirus has significantly impacted healthcare systems worldwide, exposing healthcare professionals (HCPs) to work-related stressors to prevent the spread of SARS-CoV-2. This study aimed to assess the occupational stress of HCPs in Lagos State, Nigeria, using a qualitative approach. The study involved nine HCPs from various departments, including doctors, nurses, and medical laboratory technicians. The main causes of stress were workload, policy changes, and extended use of personal protective gear. The study found high levels of occupational stress among HCPs, with workload being the main cause. The impact of the disease outbreak crisis on HCPs' lives and work demands was observed, with occupational demands categorized into safety risk at work and public perceptions. Employers and unions must respond to HCPs' needs for workplace protection and appropriate help to address stressors.

RESUMEN

Objective: To assess the factors affecting the transition of dental students from pre-clinical to clinical courses in an outcome-based curriculum. Methods: This cross-sectional study surveyed dental students in the third and fourth academic years of the Bachelor of Dental and Oral Surgery (BDS) program at the College of Dentistry, Jouf University. Ethically approved and powered by the G Power software, the study employed a modified questionnaire validated through a pilot test to assess five domains. Likert scale responses were analyzed using SPSS v.25, revealing insights into clinical workload, patient interaction, and learning experiences. Multiple regression analysis was used to assess the impact of clinical skill application, workload, transition to clinics, and patient interaction on learning experience as well as CGPA. The Mann-Whitney U test compared the ranks of two independent samples, making it less sensitive to outliers and more suitable for data with non-normal distributions. Results: In this study, the response rate of the participants was 70%. A total of 44 dental students in their third and fourth years of the program completed the survey. The multiple regression analysis showed that the predictors collectively explained 36.1% of the variance in the learning experience (Adjusted R2 = 0.361). "Transition to Clinics" had a significant positive effect on learning experience (ß = 0.292, p = 0.012), "Workload" (ß = -0.203, p = 0.393) and "Patient Interaction" (ß = 0.443, p = 0.168) were not significant predictors. The Mann-Whitney U test revealed no significant gender differences in transition to clinics, workload, patient interaction, application of clinical skills, and learning experience (U = 33.09 to -40.33, p > 0.05), but a significant difference in transition to clinics between third- and fourth-year students (U = 31.56 to -43.24, p < 0.05). Conclusion: The results of this study demonstrate that the transition to clinical training can be intricate, and that multiple elements have an impact on this process. It is crucial to have support systems that facilitate the transition into the clinical learning environment.

RESUMEN

BACKGROUND: Too high or too low patient volumes and work amounts may overwhelm health care professionals and obstruct processes or lead to inadequate personnel routine and process flow. We sought to evaluate, whether an association between current caseload, current workload, and outcomes exists in intensive care units (ICU). METHODS: Retrospective cohort analysis of data from an Austrian ICU registry. Data on patients aged ≥ 18 years admitted to 144 Austrian ICUs between 2013 and 2022 were included. A Cox proportional hazards model with ICU mortality as the outcome of interest adjusted with patients' respective SAPS 3, current ICU caseload (measured by ICU occupancy rates), and current ICU workload (measured by median TISS-28 per ICU) as time-dependent covariables was constructed. Subgroup analyses were performed for types of ICUs, hospital care level, and pre-COVID or intra-COVID period. RESULTS: 415 584 patient admissions to 144 ICUs were analysed. Compared to ICU caseloads of 76 to 100%, there was no significant relationship between overuse of ICU capacity and risk of death [HR (95% CI) 1.06 (0.99-1.15), p = 0.110 for > 100%], but for lower utilisation [1.09 (1.02-1.16), p = 0.008 for ≤ 50% and 1.10 (1.05-1.15), p < 0.0001 for 51-75%]. Exceptions were significant associations for caseloads > 100% between 2020 and 2022 [1.18 (1.06-1.30), p = 0.001], i.e., the intra-COVID period. Compared to the reference category of median TISS-28 21-30, lower [0.88 (0.78-0.99), p = 0.049 for ≤ 20], but not higher workloads were significantly associated with risk of death. High workload may be associated with higher mortality in local hospitals [1.09 (1.01-1.19), p = 0.035 for 31-40, 1.28 (1.02-1.60), p = 0.033 for > 40]. CONCLUSIONS: In a system with comparably high intensive care resources and mandatory staffing levels, patients' survival chances are generally not affected by high intensive care unit caseload and workload. However, extraordinary circumstances, such as the COVID-19 pandemic, may lead to higher risk of death, if planned capacities are exceeded. High workload in ICUs in smaller hospitals with lower staffing levels may be associated with increased risk of death.

RESUMEN

Working memory (WM) is crucial for adequate performance execution in effective decision-making, enabling individuals to identify patterns and link information by focusing on current and past situations. This work explored behavioral and electrophysiological (EEG) WM correlates through a novel decision-making task, based on real-life situations, assessing WM workload related to contextual variables. A total of 24 participants performed three task phases (encoding, retrieval, and metacognition) while their EEG activity (delta, theta, alpha, and beta frequency bands) was continuously recorded. From the three phases, three main behavioral indices were computed: Efficiency in complex Decision-making, Tolerance of Decisional Complexity, and Metacognition of Difficulties. Results showed the central role of alpha and beta bands during encoding and retrieval: decreased alpha/beta activity in temporoparietal areas during encoding might indicate activation of regions related to verbal WM performance and a load-related effect, while decreased alpha activity in the same areas and increased beta activity over posterior areas during retrieval might indicate, respectively, active information processing and focused attention. Evidence from correlational analysis between the three indices and EEG bands are also discussed. Integration of behavioral and metacognitive data gathered through this novel task and their interrelation with EEG correlates during task performance proves useful to assess WM workload during complex managerial decision-making.

RESUMEN

While individuals fail to assess their mental health subjectively in their day-to-day activities, the recent development of consumer-grade wearable devices has enormous potential to monitor daily workload objectively by acquiring physiological signals. Therefore, this work collected consumer-grade physiological signals from twenty-four participants, following a four-hour cognitive load elicitation paradigm with self-chosen tasks in uncontrolled environments and a four-hour mental workload elicitation paradigm in a controlled environment. The recorded dataset of approximately 315 hours consists of electroencephalography, acceleration, electrodermal activity, and photoplethysmogram data balanced across low and high load levels. Participants performed office-like tasks in the controlled environment (mental arithmetic, Stroop, N-Back, and Sudoku) with two defined difficulty levels and in the uncontrolled environments (mainly researching, programming, and writing emails). Each task label was provided by participants using two 5-point Likert scales of mental workload and stress and the pairwise NASA-TLX questionnaire. This data is suitable for developing real-time mental health assessment methods, conducting research on signal processing techniques for challenging environments, and developing personal cognitive load assistants.

RESUMEN

AIM: Despite the serious consequences of exposure to high job demands for nursing staff, few studies have identified pathways that could reduce the influence of high job demands on burnout. The current study aimed to exaime whether a stress mindset mitigates the positive relationship between job demands and burnout. DESIGN: A cross-sectional survey was adopted and data were collected employing self-report questionnaires. METHODS: A convenience sample of 676 nurses recruited from six regional hospitals in China were invited to complete a demographic questionnaire, the Psychological Job Demand Scale, the Stress Mindset Scale and the Burnout Scale. Hierarchical multiple regression analysis and simple slope analysis were used to examine the moderating role of stress mindset. RESULTS: Higher job demands were positively linked to burnout, and stress mindset was negatively linked to burnout. Stress mindset moderated the positive relationship between job demands and burnout. Specifically, compared to nurses with a stress-is-debilitating mindset, the relationship will be smaller for nurses holding a stress-is-enhancing mindset. PATIENT OR PUBLIC CONTRIBUTIONS: Based on these findings, nursing leaders should foster nurses' stress-is-enhancing mindset, which can ameliorate the adverse effect of job demands.

RESUMEN

The main purpose of this longitudinal study was to investigate football players' recovery status, through hormonal response, in relation to accumulated workload at two comparable time points of the first (T1) and second half (T2) of the competitive season. Moreover, this study investigated athletes' hormonal response to a typical weekly conditioning session (5 days before match: MD-5), at T1 and T2, to detect changes in players' recovery capability over time. Salivary cortisol (sC) and testosterone (sT) of 24 professional players (27.8 ± 4.1 years of age) were collected before, after, and 24 hours following MD-5 in two comparable microcycles of T1 and T2. GPS training data (total and high-intensity distance) of the 7 and 28 days before sampling were used to obtain athletes' acute and chronic workloads. Results showed a pre-training significant decrease of sT and an increase of sC (p<0.05) in T2, compared to T1. Moreover, athletes showed high sC and low sT levels before, after and 24 hours following MD-5 in T2. Workload analysis revealed significant correlations of chronic load with sC (r = 0.45, p = 0.056) and T/C ratio (r = -0.59; p = 0.007). These results suggested that, in professional football, chronic workload has a greater impact on players' recovery time than acute workload over the sport season. Moreover, athletes' hormonal response to the weekly conditioning session at T2 revealed an altered anabolic/catabolic balance, highlighting the key role of continuous internal and external workload monitoring during the season.

RESUMEN

BACKGROUND: Mentoring in academic nursing facilitates the acclimation of nurse faculty into academia, supports career development, and improves faculty satisfaction and retention. While studies have examined the characteristics of effective mentors, few have examined institutional influences on academic mentoring for faculty. PURPOSE: To identify institutional factors that support or hinder faculty-to-faculty academic mentoring from the perspectives of experienced nurse faculty mentors. METHOD: A qualitative descriptive approach was used to identify institutional factors that impact academic mentoring. Semi-structured interviews were conducted with experienced nurse faculty (n = 24) about their mentoring experiences. Remarks related to institutional factors were analyzed using conventional content analysis. RESULTS: Five institutional factors that supported mentoring were identified: (1) support of unit leaders, (2) established processes and policies, (3) mentoring development opportunities, (4) faculty-to-faculty support, and (5) faculty rewards. Six institutional factors that hindered mentoring were identified: (1) lack of support of unit leaders, (2) limited mentoring development opportunities, (3) heavy workloads that restrict mentoring, (4) limited pool of mentors, (5) inadequate faculty rewards for mentoring, and (6) limited oversight of faculty mentoring. CONCLUSION: The identification of institutional factors that support or hinder mentoring can inform academic leaders and program administrators in their efforts to strengthen mentoring.

RESUMEN

BACKGROUND: Little is known about factors contributing to burnout and intent to leave in cardiologists and other cardiology health care workers. METHODS AND RESULTS: The Coping With COVID survey assessed work conditions, burnout, and intent to leave among physicians, nurses, advanced practice providers, and other clinical staff (OCS) from April 2020 to December 2020. Single-item measures assessed work conditions, burnout (emotional exhaustion), and intent to leave. Multilevel logistic regression examined work life variables' relationships to burnout among role types and feeling valued as a mediator. Open-ended comments analyzed via grounded theory contributed to a conceptual model. Coping With COVID was completed by 1199 US cardiology health care workers (354 physician/520 nurses/198 advanced practice providers/127 OCS). Nurses were most likely to report burnout (59% nurses, 57% OCS, 46% advanced practice providers, 40% physicians, P<0.0001). Workload correlated with burnout in all groups (adjusted odds ratios [aORs], 4.1-17.4; Ps<0.005), whereas anxiety/depression related to burnout in all except OCS (aORs, 3.9-8.3; Ps≤0.001). Feeling valued was related to lower burnout in most groups. Intent to leave was common (23%-45%) and was lower in physicians and advanced practice providers who felt valued (aORs, 0.26 and 0.22, respectively; Ps<0.05). Burnout was highest for nurses in practice 16 to 20 years, and intent to leave was highest for OCS in practice 16 to 20 years. Themes contributing to burnout included personal and patient safety, leadership, and financial issues. CONCLUSIONS: Burnout was prevalent among cardiology health care workers and highest in nurses and OCS. Addressing factors associated with burnout in different role types may improve work life sustainability for all cardiology health care workers.

RESUMEN

BACKGROUND: Individuals working excessive hours is a worldwide phenomenon. In Indonesia, over 32 million people work more than 40 h per week, contributing to around 26% of the workforce. Excessive working may affect health, increasing the risk of cardiovascular diseases such as hypertension. Hypertension affected around 34% of Indonesian adults, approximately 63.3 million people and led to about 427,000 deaths in 2018, and the prevalence remains high at 29.2% in 2023. This study aims to analyze the relationship between work hours and the risk of hypertension among working individuals in Indonesia. METHODS: This study used a pooled cross-sectional data from the Indonesian Family Life Survey (IFLS) wave 4 (2007) and wave 5 (2014) and performed a logit regression analysis to examine the likelihood of a working individual having hypertension based on the individual's work hours. A dummy variable of hypertension is created based on the result of blood pressure measurement. The sample consists of 22,500 working individuals in Indonesia. This study controlled for job characteristics, sociodemographic status and health-behavioral risk factors such as BMI and smoking behavior, and performed additional regression analyses for alternative models to check for robustness. RESULTS: Our findings showed that there is a higher probability of having hypertension for workers who work longer hours by 0.06% points for each additional hour of work (p < 0.01). Other factors such as physical activity and smoking behavior have also been demonstrated to be significantly correlated to the risk of hypertension. CONCLUSIONS: This study revealed a positive relationship between work hours and hypertension. Although this study cannot suggest causality, the strongly significant correlation may provide an idea and an overview regarding the risk of hypertension among working individuals in Indonesia. The Indonesian government could consider conducting further studies to implement and promote flexible working arrangements initiatives and incentive programs to improve workers' health outcomes.

RESUMEN

BACKGROUND: The COVID-19 pandemic posed an enormous challenge on the public health workforce, leading to the hiring of much temporary staff. Temporary staff may experience poorer working conditions compared to permanent staff. From a public health perspective, we need to know how working conditions are experienced when there is an acute pressure on recruiting sufficient public health care staff. This study aimed to investigate differences in job demands and work functioning between temporary and permanent public health care staff, during the fourth wave of the COVID-19 pandemic in the Netherlands and compare it with available pre-pandemic data from the general working population. METHODS: This cross-sectional study included temporary (n = 193) and permanent (n = 98) public health care staff from a municipal health care service in the north of the Netherlands. The participants completed a questionnaire with items about quantitative, cognitive, emotional demands (Copenhagen PsychoSOcial Questionnaire, COPSOQ, range 1-100) and work functioning (Work Role Functioning Questionnaire, WRFQ, range 1-100). The participants' scores were compared to the general working population and differences between temporary and permanent staff were investigated using linear regression analysis. In addition, explorative analyses were conducted with temporary staff stratified by task and permanent staff by department. RESULTS: Permanent staff had relatively high scores on job demands compared to the general working population, whereas temporary staff had relatively low scores. On work functioning, permanent staff had similar scores as the general working population and temporary staff had better scores. Compared to permanent staff, temporary staff had lower, i.e. better, scores on quantitative (regression coefficient (B)=-26.7; 95% Confidence Interval (CI) -30.8 to -22.5), cognitive (B=-24.4; 95% CI -29.0 to -19.9), and emotional demands (B=-11.8; 95% CI -16.0 to -7.7), and better scores on work functioning (B = 7.8; 95% CI 4.5 to 11.3). CONCLUSIONS: Temporary staff experienced lower job demands and reported better work functioning than permanent staff. The acute expansion of the public health workforce did not seem to negatively impact the job demands and work functioning of temporary public health care staff.

RESUMEN

Robot-assisted surgery (RAS) differs from traditional OR set-ups in several ways such as operation of technology and obstructed team communication that potentially affect surgical staff's stress experiences. The current study investigates the effects of key intraoperative job demands and resources on mental workload and perceived stress in RAS. We focused on the role of intraoperative teamwork as a resource that potentially reduces occupational stress. Combining standardized expert observations in the OR with healthcare providers' self-reports, the study involved two types of robot-assisted, urological interventions. The sample consisted of 73 observed surgeries and included 242 post-operative surveys on perceived stress and mental workload from surgeons and surgical nurses. Multilevel regression analyses reveal differential effects for stress and workload. Importantly, whereas better surgical teamwork was associated with lower stress, it was unrelated to workload. Our findings provide a nuanced picture of occupational stress in RAS, particularly regarding the role of intraoperative teamwork.

RESUMEN

Understanding the operator's cognitive workload is crucial for efficiency and safety in human-machine systems. This study investigated how cognitive workload modulates cardiac autonomic regulation during a standardized military simulator flight. Military student pilots completed simulated flight tasks in a Hawk flight simulator. Continuous electrocardiography was recorded to analyze time and frequency domain heart rate variability (HRV). After the simulation, a flight instructor used a standardized method to evaluate student pilot's individual cognitive workload from video-recorded flight simulator data. Results indicated that HRV was able to differentiate flight phases that induced varying levels of cognitive workload; an increasing level of cognitive workload caused significant decreases in many HRV variables, mainly reflecting parasympathetic deactivation of cardiac autonomic regulation. In conclusion, autonomic physiological responses can be used to examine reactions to increased cognitive workload during simulated military flights. HRV could be beneficial in assessing individual responses to cognitive workload and pilot performance during simulator training.

RESUMEN

Based on the signaling and conservation of resources theories, this study aims to identify different strategic organizational profiles related to occupational health and well-being (OHWB). Additionally, this study explores how these various organizational profiles impact employees' well-being, specifically in relation to absenteeism, emotional exhaustion, work overload, intention to quit, and job satisfaction. Data were collected from 59 organizations and 2828 employees. The first phase of this study presents the latent profile analysis carried out to identify OHWB organizational profiles. This analysis reveals four organizational profiles that are metaphorically named according to the growth stages of plants (i.e., wasteland, sprouting, budding, and blooming OHWB profiles). The second phase of this study investigates the associations between the latent profiles assigned to the organizations with absenteeism, intention to quit, emotional exhaustion, feelings of work overload, and job satisfaction among their employees using MANOVA. The results show that organizational profiles influence employees' health and well-being. Employees working in organizations with a low OHWB profile, known as the "wasteland profile", tend to report more days of absenteeism, higher levels of emotional exhaustion, greater work overload, and lower job satisfaction. Employees are also more likely to express a greater intention to quit their jobs than those working in organizations with a higher OHWB profile (a "blooming profile"). This study is useful for organizations and practitioners seeking to understand how investing in a health and well-being strategy can benefit their employees.

RESUMEN

Pilot behavior is crucial for aviation safety. This study aims to investigate the EEG characteristics of pilots, refine training assessment methodologies, and bolster flight safety measures. The collected EEG signals underwent initial preprocessing. The EEG characteristic analysis was performed during left and right turns, involving the calculation of the energy ratio of beta waves and Shannon entropy. The psychological workload of pilots during different flight phases was quantified as well. Based on the EEG characteristics, the pilots' psychological workload was classified through the use of a support vector machine (SVM). The study results showed significant changes in the energy ratio of beta waves and Shannon entropy during left and right turns compared to the cruising phase. Additionally, the pilots' psychological workload was found to have increased during these turning phases. Using support vector machines to detect the pilots' psychological workload, the classification accuracy for the training set was 98.92%, while for the test set, it was 93.67%. This research holds significant importance in understanding pilots' psychological workload.

RESUMEN

The assessment of the cognitive workload experienced by air traffic controllers is a complex and prominent issue in the research community. This study introduces new indicators related to gamma waves to detect controllers' workload and develops experimental protocols to capture their EEG data and NASA-TXL data. Then, statistical tests, including the Shapiro-Wilk test and ANOVA, were used to verify whether there was a significant difference between the workload data of the controllers in different scenarios. Furthermore, the Support Vector Machine (SVM) classifier was employed to assess the detection accuracy of these indicators across four categorizations. According to the outcomes, hypotheses suggesting a strong correlation between gamma waves and an air traffic controller's workload were put forward and subsequently verified; meanwhile, compared with traditional indicators, the indicators associated with gamma waves proposed in this paper have higher accuracy. In addition, to explore the applicability of the indicator, sensitive channels were selected based on the mRMR algorithm for the indicator with the highest accuracy, ß + θ + α + γ, showcasing a recognition rate of a single channel exceeding 95% of the full channel, which meets the requirements of convenience and accuracy in practical applications. In conclusion, this study demonstrates that utilizing EEG gamma wave-associated indicators can offer valuable insights into analyzing workload levels among air traffic controllers.

RESUMEN

The effective management of human resources in nursing is fundamental to ensuring high-quality care. The necessary staffing levels can be derived from the nursing-related health status. Our approach is based on the use of artificial intelligence (AI) and machine learning (ML) to recognize key workload-driving predictors from routine data in the first step and derive recommendations for staffing levels in the second step. The precedent analysis was a multi-center study with data provided by three hospitals. The SPI (Self Care Index = sum score of 10 functional/cognitive items of the epaAC (epaAC = nursing assessment tool for AcuteCare (abbreviated from the German-language effiziente Pflege-Analyse AcuteCare))) was identified as a strong predictor of nursing workload. The SPI alone explains the variance in minutes with an adjusted R2 of 40% to 66%. With the addition of further predictors such as "fatigue" or "pain intensity", the adjusted R2 can be increased by up to 17%. The resulting model can be used as a foundation for data-based personnel controlling using AI-based prediction models.

RESUMEN

In May 2022, Hyogo Medical University Hospital introduced protocol-based pharmacotherapy management(PBPM), which is jointly planned by doctors and pharmacists, for certain cancer drug therapies. Colorectal cancer patients who underwent outpatient cancer chemotherapy in the Department of Lower Gastrointestinal Surgery from October to December 2021(before the introduction of PBPM)and from May to August 2022(after the introduction of PBPM)were retrospectively studied. The proportion of clinical examinations performed, number of prescription questions, and time taken by pharmacists to solve the prescription questions before and after the introduction of PBPM were compared. Additionally, the number of modifications made in the medical record by pharmacists on behalf of doctors in response to the prescription questions was assessed. The proportion of clinical examinations performed(clinical examinations actually performed/clinical examinations that should have been performed)improved from 93.2%(260/279)before to 98.8%(405/410)after the introduction of PBPM(p<0.001). The number of prescription questions decreased from an average of 64.7(±11.9)per month before to an average of 29.5(±3.4)per month after the introduction of PBPM. The average number of modifications made in the medical record by pharmacists on behalf of the doctors in response to the prescription questions was 25.8(±5.4)per month after the introduction of PBPM. There was no significant difference before and after the introduction of PBPM in regard to the median(interquartile range)time taken by pharmacists to solve the prescription questions (before PBPM: 1.88 minutes per case[1.70-2.28 minutes]; after PBPM: 1.71 minutes per case[1.61-2.06 minutes][p= 0.75]). The increased proportion of clinical examinations performed after the implementation of PBPM may have improved the safety of cancer drug management, and the decreased number of prescription questions is speculated to have led to a reduction in physician workload.

RESUMEN

Objective: The study aimed to compare the differences in the performance of seven session-rating of perceived exertion (RPE)-derived metrics (coupled and uncoupled acute: chronic workload ratio (ACWR), weekly ratio of workload change, monotony, standard deviation of weekly workload change, exponentially weighted moving average (EWMA), and robust exponential decreasing index (REDI)) in classifying the performance of an injury prediction model after taking into account the time series (no latency, 5-day latency, and 10-day latency). Design: The study documented the RPE of eight curlers in their daily training routine for 211 days prior to the Olympic Games. Methods: Seven Session-RPE (sRPE)-derived metrics were used to build models at three time series nodes using logistic regression and multilayer perceptron. Receiver operating characteristic plots were plotted to evaluate the model's performance. Results: Among the seven sRPE-derived metrics multilayer perceptron models, the model without time delay (same-day load corresponding to same-day injury) exhibited the highest average classification performance (86.5%, AUC = 0.773). EMWA and REDI demonstrated the best classification performance (84.4%, p < 0.001). Notably, EMWA achieved the highest classifying accuracy in the no-delay time series (90.0%, AUC = 0.899), followed by the weekly load change rate under the 5-day delay time series (88.9%, AUC = 0.841). Conclusion: EWMA without delay is a more sensitive indicator for detecting injury risk.

RESUMEN

Study purpose: To assess the prevalence of burnout among radiographers, and whether demographic variables and work-related factors had any influence on burnout and perceived stress among them. Methods: A cross-sectional quantitative survey design is adopted in this study. The participants included radiographers from Saudi Arabia. Both Maslach Burnout Inventory (MBI) and Perceived Stress Scale (PSS) were used for data collection. Participation was voluntary, and the survey was conducted online, resulting in 322 final responses considered for the data analysis. Results: The mean emotional exhaustion (EE) score achieved was 26.01, representing medium burnout risk. However, the mean depersonalization (DP: µ = 25.25) and personal accomplishment (PA: µ = 23.65) represented high burnout risk among radiographers. Statistically significant differences (p < 0.05) were observed among the participants grouped by genders, age groups, nature of work type, and work experience. The mean perceived stress score for radiographers was identified to be 27.8, indicating high. Conclusion: The findings underscore the critical need for targeted interventions and support mechanisms within the radiology profession, particularly focusing on younger radiographers and those with extensive work experience.
