Burnout, stress and Type D personality amongst hospital/emergency physicians.

INTRODUCTION: In previous studies, physicians have been identified as a high-risk group for burnout. Although the work environment has received more attention than specific determinants of personality traits, the latter might contribute to burnout. STUDY OBJECTIVE: We aimed to investigate the association of Type D personality, job and organizational determinants with burnout, stress and work engagement as outcome factors among emergency physicians and hospital physicians working in intensive care and surgery departments. We specifically focused on our group of emergency physicians. METHODS: In this cross-sectional study, self-report questionnaires were distributed via social media using a specific survey link to 531 Belgian hospital physicians working at the Emergency Department, Intensive Care, and Surgery Department between October 21, 2018, and April 11, 2019. The survey instrument included questions about sociodemographic characteristics, job characteristics, organizational factors, job satisfaction, social support by supervisors and colleagues (Leiden Quality of Work Questionnaire for Medical Doctors) and Type D personality (Distress Scale-14) and as outcomes burnout (Oldenburg Burnout Inventory) and work engagement (Utrecht Work Engagement Scale). A multiple regression analysis was used to examine the associations between the determinants and each of the outcomes with emergency physicians as the study population. RESULTS: Eligible data were available for 436 questionnaires and involved 212 emergency physicians, 162 other hospital physicians (Intensive Care and Surgery Department) and 62 residents concerning both groups of physicians. Type D personality ranged from 28.5 to 29.1% in emergency physicians and other hospital physicians. Additionally, even after correcting for job-related and organizational factors, emergency physicians with Type D personality were seven times more likely to have a high risk for burnout. CONCLUSION: As a result, this study offers a new perspective on the associations between burnout, stress and Type D personality. Type D personality might be a personality-related risk factor for burnout among emergency physicians. Therefore, we recommend enhanced prevention measures that take into account this individual factor in the further development of coaching programs. Improving the professional well-being of emergency physicians is necessary, especially in the scope of the recent COVID-19 pandemic, which has put a high demand on acute and emergency care departments.

The Role of Psychological Distress in the Relationship between Drinking Motives and Hazardous Drinking in Older Adults.

INTRODUCTION: Drinking motives seem to be the most proximal predictors of alcohol outcomes. Consequently, these are an essential factor to consider as they may influence the extent to which alcohol is used in a risky way, even in older adults. OBJECTIVE: We studied the moderating effect of distress on the relationship between drinking motives and drinking behaviour in a community-dwelling older adult sample. METHOD: In a retrospective cross-sectional research study, participants were community-dwelling older adults aged 65 years and older. All respondents completed a questionnaire covering the Drinking Motives Questionnaire (DMQ), the Alcohol Use Disorders Identification Test (AUDIT), and the General Severity Index (GSI) of the Brief Symptom Inventory (BSI). RESULTS: In this sample of 1,148 older adults, drinking motives and hazardous alcohol use were associated (enhancement motives r = 0.478, p < 0.001; coping motives r = 0.367, p < 0.001; and social motives r = 0.235, p < 0.001). Furthermore, moderation analysis showed that older adults drinking predominantly for enhancement or coping motives (respectively, ß = 0.433, CI [95%] = 2.557-3.222 and ß = 0.327, CI [95%] = 1.077-1.491, p < 0.001), and older adults who had higher levels of psychological distress (ß = 2.518, CI [95%] = 2.017-3.019, p < 0.001) were more likely to report higher degree of hazardous alcohol use. CONCLUSION: The relations between coping drinking motives and enhancement drinking motives on hazardous drinking depended on the level of distress. The associations between drinking for coping and drinking for enhancement were stronger in high levels of distress. Although causality cannot be interpreted from cross-sectional data, tackling psychological distress and drinking to cope with negative affect or to enhance positive affect might have strong effects on reducing hazardous drinking behaviour among older adults.

Leadership in Nursing Excellence: The Magnet Recognition® Journey Experiences in Europe.

Improving work conditions and the provision of high-quality care and patient safety is an issue in European hospitals. Inspired by a US program for nursing excellence, Magnet Recognition, a Belgian hospital shared their experiences by organizing a summer school in 2019 with nurses of 21 hospitals from 9 countries. This article explains the hospital's research program, the link between the journey and the content of the summer school, lessons learned, and the extent to which participants of European hospitals were interested in nursing excellence and Magnet designation.

Staff empowerment and engagement in a magnet® recognized and joint commission international accredited academic centre in Belgium: a cross-sectional survey.

BACKGROUND: A substantial number of studies linked aspects of a balanced, healthy and supportive nurse practice environment with quality and patient safety. To what extent balanced work characteristics such as social capital, decision latitude and workload are relevant for all staff engaged in patient care including healthcare and medical staff in a Magnet Recognized and Joint Commission International accredited academic centre is unclear. The study aim is to investigate associations between work characteristics such as social capital, decision latitude and workload, work engagement and feelings of burnout as explanatory variables and job satisfaction, turnover intentions and perceived quality of care as dependent variables in a study population of nursing, healthcare and medical staff taken in account generation differences. METHODS: Hierarchical regression analysis estimated strength of associations with demographic characteristics (block-1), professional category (block-2), work characteristics (block-3) and work engagement or burnout dimensions (block-4) as explanatory variables of job satisfaction and turnover intention and quality of care as outcome variables. RESULTS: The study confirmed and extended previous study findings demonstrating positive impact on staff' job outcomes and assessed quality of care by balanced work characteristics such as social capital, decision latitude and workload in nursing staff (N = 864), healthcare staff (N = 131) and medical staff (N = 241). Generational characteristics and professional category were associated with turnover intentions and less favorable assessed quality of care, respectively. Explained variances of studied models ranged from 14.4 to 45.7%. CONCLUSION: Engaging and committing staff to promote excellent patient outcomes in daily interdisciplinary practice works through clear frameworks, methods and resources supported by governance and policy structure that makes outcomes visible and accountable.

Vulnerability to burnout within the nursing workforce-The role of personality and interpersonal behaviour.

AIMS AND OBJECTIVES: To study the combination of personality and interpersonal behaviour of staff nurses in general hospitals in relation to burnout and its separate dimensions. BACKGROUND: More research on the individual factors contributing to the development of burnout is needed to improve the risk profile of nursing staff. Therefore, a combination of Leary's interpersonal circumplex model, which depicts the interpersonal behaviour trait domain, and the five-factor model was considered in the study at hand. DESIGN: A cross-sectional research method was applied using self-report questionnaires. METHODS: A total of 880 Belgian general hospital nurses were invited to participate in the study. Data were collected from November 2012-July 2013. The questionnaire consisted of three validated self-report instruments: the NEO five-factor inventory, the Dutch Interpersonal Behaviour Scale and the Maslach Burnout Inventory. RESULTS: Of the 880 nurses invited to participate, 587 (67%) returned the questionnaire. Sex, neuroticism, submissive-friendly behaviour, dominant-friendly behaviour and vector length were found to be predictive factors for emotional exhaustion. For depersonalisation, sex, neuroticism, conscientiousness, friendly behaviour, submissive-friendly behaviour, dominant-hostile behaviour and vector length were predictive factors. Finally, personal accomplishment was determined by neuroticism, openness, conscientiousness, and hostile behaviour. CONCLUSIONS: This study confirmed the influence of the Big Five personality factors on the separate dimensions of burnout. Interpersonal behaviour made a significant contribution to the predictive capacity of the regression models of all three dimensions of burnout. Additional longitudinal research is required to confirm the causal relationship between these individual factors and burnout. RELEVANCE TO CLINICAL PRACTICE: The results of this study can help to achieve a better understanding of which vulnerabilities an individual prevention programme for burnout should target. In addition, hospitals could use assessment instruments to identify nurses who are prone to burnout and thus would benefit from additional support or stress reduction programmes.

Predictors of burnout, work engagement and nurse reported job outcomes and quality of care: a mixed method study.

BACKGROUND: High levels of work-related stress, burnout, job dissatisfaction, and poor health are common within the nursing profession. A comprehensive understanding of nurses' psychosocial work environment is necessary to respond to complex patients' needs. The aims of this study were threefold: (1) To retest and confirm two structural equation models exploring associations between practice environment and work characteristics as predictors of burnout (model 1) and engagement (model 2) as well as nurse-reported job outcome and quality of care; (2) To study staff nurses' and nurse managers' perceptions and experiences of staff nurses' workload; (3) To explain and interpret the two models by using the qualitative study findings. METHOD: This mixed method study is based on an explanatory sequential study design. We first performed a cross-sectional survey design in two large acute care university hospitals. Secondly, we conducted individual semi-structured interviews with staff nurses and nurse managers assigned to medical or surgical units in one of the study hospitals. Study data was collected between September 2014 and June 2015. Finally, qualitative study results assisted in explaining and interpreting the findings of the two models. RESULTS: The two models with burnout and engagement as mediating outcome variables fitted sufficiently to the data. Nurse-reported job outcomes and quality of care explained variances between 52 and 62%. Nurse management at the unit level and workload had a direct impact on outcome variables with explained variances between 23 and 36% and between 12 and 17%, respectively. Personal accomplishment and depersonalization had an explained variance on job outcomes of 23% and vigor of 20%. Burnout and engagement had a less relevant direct impact on quality of care (≤5%). The qualitative study revealed various themes such as organisation of daily practice and work conditions; interdisciplinary collaboration, communication and teamwork; staff nurse personal characteristics and competencies; patient centeredness, quality and patient safety. Respondents' statements corresponded closely to the models' associations. CONCLUSION: A deep understanding of various associations and impacts on studied outcome variables such as risk factors and protective factors was gained through the retested models and the interviews with the study participants. Besides the softer work characteristics - such as decision latitude, social capital and team cohesion - more insight and knowledge of the hard work characteristic workload is essential.

Impact of childhood trauma on postpartum depression: a prospective study.

Studies on the impact of childhood trauma on postpartum depression show inconsistencies and methodological limitations. The present study examines the effect of childhood trauma on depression 12 and 24 weeks after childbirth, while controlling for history of depression, depression symptoms during pregnancy and type D personality. During the third trimester of pregnancy, 210 women completed self-report questionnaires assessing depression (current and/or past episodes), childhood trauma and type D personality, of whom 187 participated in the postpartum follow-up, with depression symptoms being reassessed at 12 and 24 weeks after delivery with three depression outcome measures. Eventually, 183 participants were retained for analysis. Results indicated no predictive value of childhood trauma on postpartum depression in the univariate analyses, nor after controlling for previous depression, depression symptoms during pregnancy and type D personality. However, past depression and depression symptoms during pregnancy did independently and convincingly predict postpartum depression, especially at 12 weeks and to a lesser extent at 24 weeks following childbirth. Overall, we found no significant association between childhood trauma and postpartum depression. Past depression and depression symptoms during pregnancy are more relevant factors to assess before childbirth.

Interpersonal behaviour in relation to burnout.

Organisational and work-related challenges faced by midwives make them vulnerable to burnout, but individual factors, such as interpersonal behaviour, can also contribute. A study in eight hospitals in the Dutch-speaking part of Belgium investigated the prevalence of burnout among Flemish midwives, assessed their interpersonal behaviour, and explored the relationship between interpersonal behaviour, burnout, job satisfaction and intention to leave. This article describes the study and reports the findings.

Combining the Nurse Intuition Patient Deterioration Scale with the National Early Warning Score provides more Net Benefit in predicting serious adverse events: A prospective cohort study in medical, surgical, and geriatric wards.

OBJECTIVES: This prospective cohort study aimed to assess the predictive value of the Nurse Intuition Patient Deterioration Scale (NIPDS) combined with the National Early Warning Score (NEWS) for identifying serious adverse events in patients admitted to diverse hospital wards. RESEARCH METHODOLOGY/DESIGN: Data was collected between December 2020 and February 2021 in a 350-bed acute hospital near Brussels, Belgium. The study followed a prospective cohort design, employing NIPDS alongside NEWS for risk assessment. Patients were monitored for 24 h post-registration, with outcomes recorded. SETTING: The study was conducted in a hospital with a Rapid Response System (RRS) and electronic patient record wherein NEWS was routinely collected. Patients admitted to two medical, two surgical, and two geriatric wards were included. MAIN OUTCOME MEASURES: The primary outcome included death, urgent code calls, or unplanned ICU transfers within 24 h after NIPDS registration. The secondary outcome comprised rapid response team activations or changes in Do-Not-Resuscitate codes. RESULTS: In a cohort of 313 patients, 10/313 and 31/313 patients reached the primary and secondary outcome respectively. For the primary outcome, NIPDS had a sensitivity of 0.900 and specificity of 0.927, while NEWS had a sensitivity of 0.300 and specificity of 0.974. Decision Curve Analysis demonstrated that NIPDS provided more Net Benefit across various Threshold Probabilities. Combining NIPDS and NEWS showed potential for optimizing rapid response systems. Especially in resource-constrained settings, NIPDS could be used as a calling criterion. CONCLUSION: The NIPDS displayed strong predictive capabilities for adverse events. Integrating NIPDS into existing rapid response systems can objectify nurse intuition, enhancing patient safety. IMPLICATIONS FOR CLINICAL PRACTICE: The Nurse Intuition Patient Deterioration Scale (NIPDS) is a valuable tool for detecting patient deterioration. Implementing NIPDS alongside traditional scores such as NEWS can improve patient care and safety. The optimal NIPDS threshold to activate rapid response is ≥5.

Personalized pulmonary rehabilitation program for patients with post-acute sequelae of COVID-19: A proof-of-concept retrospective study.

Long-COVID patients present with a decline in physical fitness. The aim of this study is to reveal the impact of pulmonary rehabilitation (PR) on physical fitness, quality of life (QoL), and parameters of quantified thorax CT. Long-COVID patients enrolled in a 3-month PR program were retrospectively studied. PR included endurance and resistance training three times a week. Assessments pre- and post-rehabilitation included quantified chest CT, pulmonary function tests (PFT), six-minute walk test (6MWT), cardiopulmonary exercise test, and questionnaires: Hospital Anxiety and Depression Scale, post-COVID-19 Functional Status scale, Borg score, and EuroQol. Seventeen subjects (5M/12F), mean age 42 ± 13 years, were included. PR improved all questionnaires' results significantly. Only significant difference in PFT parameters was correlation between baseline total lung capacity (TLC) and difference in TLC pre- and post-rehabilitation (p = 0.002). 6MWT increased from 329 to 365 m (p < 0.001), VO2max changed from 21 to 24 mL/kg/min (p = 0.007), peak load increased from 116 to 141 Watt (p < 0.001). Blood volume in small pulmonary vessels of 1.25 to 5 mm2 in cross-sectional area (BV5%) was higher than observed in patients with acute COVID-19 infection. After rehabilitation, BV5% decreased from 65% to 62% (p = 0.020). These changes correlated directly with changes in TLC (p = 0.039). Quantified CT airway volume increased after rehabilitation (p = 0.013). After rehabilitation, TLC tended to normalize due to (re)opening of small airways, with decline in air trapping and recruitment of alveoli. Furthermore, this study revealed that pulmonary rehabilitation can improve QoL and physical fitness in long-COVID patients.

Dissociative symptoms and sleep parameters--an all-night polysomnography study in patients with insomnia.

BACKGROUND: Dissociative disorders encompass a range of symptoms varying from severe absent-mindedness and memory problems to confusion about one's own identity. Recent studies suggest that these symptoms may be the by-products of a labile sleep-wake cycle. METHODS: In the current study, we explored this issue in patients suffering from insomnia (N=46). We investigated whether these patients have raised levels of dissociative symptoms and whether these are related to objective sleep parameters. Patients stayed for at least one night in a specialized sleep clinic, while sleep EEG data were obtained. In addition, they completed self-report measures on dissociative symptoms, psychological problems, and sleep characteristics. RESULTS: Dissociative symptom levels were elevated in patients suffering from insomnia, and were correlated with unusual sleep experiences and poor sleep quality. Longer REM sleep periods and less time spent awake during the night were predictive of dissociation. CONCLUSIONS: This is the first study to show that insomnia patients have raised dissociative symptom levels and that their dissociative symptoms are related to objective EEG parameters. These findings are important because they may inspire sleep-related treatment methods for dissociative disorders.

Weight during the postpartum period: what can health care workers do?

To describe the gestational month-to-month weight change, obstetric and lifestyle factors influencing postpartum weight retention (PPWR) and to suggest possible interventions to prevent PPWR. This study was part of a larger research project concerning maternal weight change after childbirth. 343 women were recruited on five maternity wards in the Antwerp region, Belgium. Weight and height were assessed by the researchers during two home visits at 3 and 14 months postpartum and participants completed a questionnaire investigating obstetric and lifestyle factors during the first home visit. The monthly weights in between the home visits were self-reported by the participants. Full data were available for 75 women. One year after childbirth 52.0 % of the women faced postpartum weight retention. The different monthly weight points within the changes differed significantly from each other up to sixth months postpartum. Prepregnancy weight, exceeding the recommendations from the Institute of Medicine (IOM) concerning weight gain during pregnancy, smoking behaviour and exercising during pregnancy significantly influenced the postpartum weight change. The amount of weight gained during pregnancy, breastfeeding, possible postpartum depression and experiencing a shortage of information concerning the weight change after childbirth significantly influenced postpartum weight retention. Weight gain during pregnancy, exceeding IOM-criteria, breastfeeding, depression and lack of information determine PPWR and can be modulated by interventions such as routine weighing or screening of pregnant women. Several of these influencing factors can be preventively influenced by health care workers. Overall, we believe women could benefit from more guidance before, during and after pregnancy. Moreover, we recommend to reintroduce routine weighing of pregnant women as weight gain during pregnancy seems one of the most important factors involved in PPWR.

Predicting patient deterioration by nurse intuition: The development and validation of the nurse intuition patient deterioration scale.

INTRODUCTION: Early warning scores based on vital signs are used in hospitals to estimate patient deterioration and to initiate an adequate and timely response when necessary. These scores show acceptable performance in predicting patient outcomes. However, they tend to generate many false positives leading to an increased workload in clinical practice. Additionally, nurses feel a tension between the application of an early warning score and their own clinical judgement. Nurse intuition is often included as an extra call criterion next to an early warning score. It is therefore important to investigate its predictive value. The aim of this study was to develop and validate a Nurse Intuition Patient Deterioration Scale (NIPDS). METHODS: The NIPDS was developed using the latest evidence after which relevant items were selected by an expert panel. The scale was tested in a prospective observational study in 2 surgical and 2 medical wards in a Belgian hospital. Data were collected from December 1st, 2019 until March 31st, 2020. A NIPDS registration was done at each patient admission and whenever the attending nurse felt worried. The studied outcomes were urgent physician assistance call, resuscitation team call, patient death, and unplanned transfer to intensive/medium care. Psychometric analyses and scale optimisation were carried out using Rasch modelling techniques. Finally, the scale's accuracy and an optimal threshold were determined. RESULTS: The scale item content validity index is 0.88 indicating that the selected items should be included in the instrument according to the expert panel. Item-total score correlation coefficients range between 0.573 (item 9 - pain) and 0.874 (item 6 - behaviour). The Person Separation Index is 0.814 indicating satisfactory discriminatory power. An overall fit of the NIPDS data to the Rasch model was confirmed. Rasch modelling showed that the item 'pain' signalled misfit. Furthermore, the person-item map showed disordered items which were corrected in the final model. The AUROC to predict an event within 24 h after registration was 0.957 (95% CI 0.932-0.982; p < 0.001) indicating excellent model performance. DISCUSSION: The results showed that the NIPDS is a valid and accurate instrument to predict events in surgical and medical patients. It showed better performance compared to an existing score estimating nurse intuition. In practice, the NIPDS could be used by nurses to estimate clinical deterioration in addition to an early warning score. It remains unclear if the combination of NIPDS with an early warning score could reduce workload without losing accuracy and this should be explored in future research. TWEETABLE ABSTRACT: Newly developed nurse intuition scale, which uses clinical cues to estimate deterioration in hospitalised patients, is brief and performs well in predicting physician assistance, resuscitation team calls, patient death and unplanned transfer to intensive or medium care.

Unraveling pathophysiologic mechanisms contributing to symptoms in patients with post-acute sequelae of COVID-19 (PASC): A retrospective study.

Patients with post-acute sequelae of COVID-19 (PASC) present with a decrease in physical fitness. The aim of this paper is to reveal the relations between the remaining symptoms, blood volume distribution, exercise tolerance, static and dynamic lung volumes, and overall functioning. Patients with PASC were retrospectively studied. Pulmonary function tests (PFT), 6-minute walk test (6MWT), and cardiopulmonary exercise test were performed. Chest CT was taken and quantified. Patients were divided into two groups: minor functional limitations (MFL) and severe functional limitations (SFL) based on the completed Post-COVID-19 Functional Status scale (PCFS). Twenty one patients (3 M; 18 FM), mean age 44 (IQR 21) were studied. Eighteen completed the PCFS (8 MFL; 10 SFL). VO2 max was suboptimal in both groups (not significant). 6MWT was significantly higher in MFL-group (p = 0.043). Subjects with SFL, had significant lower TLC (p = 0.029). The MFL-group had more air trapping (p = 0.036). Throughout the sample, air trapping correlated significantly with residual volume (RV) in L (p < 0.001). An increase in air trapping was related to an increase in BV5 (p < 0.001). Mean BV5 was 65% (IQR 5%). BV5% in patients with PASC was higher than in patients with acute COVID-19 infection. This increase in BV5% in patients with PASC is thought to be driven by the air trapping in the lobes. This study reveals that symptoms are more driven by occlusion of the small airways. Patients with more physical complaints have significantly lower TLC. All subjects encounter physical limitations as indicated by suboptimal VO2 max. Treatment should focus on opening or re-opening of small airways by recruiting alveoli.

Self-reported body weight and height on admission to hospital: a reliable method in multi-professional evidence-based nutritional care?

Screening patients' nutritional status on admission to hospital is recommended by evidence-based guidelines on malnutrition. In practice, self-reported values for body weight and height are often used by nurses and dieticians. This study assessed the accuracy of self-reported body weight and height and whether these self-reported values might be influenced by the nature of the health-care worker involved. Patients (n = 611) on admission reported their body weight and height to a nurse and a dietician. Reported values were analysed and compared with the measured values. Self-reported values for body weight and height on admission are not always accurate. Patients do report different values to different health-care workers. Self-reported values for body weight to nurses were more accurate as compared with dieticians. Self-reported values for body weight and height are subject to observer bias and should be used with caution in nutritional screening and multi-professional nutritional care.

Sufficient personal protective equipment training can reduce COVID-19 related symptoms in healthcare workers: A prospective cohort study.

BACKGROUND: The association between inadequate personal protective equipment during the COVID-19 pandemic and an increased risk of SARS-CoV-2 infection in frontline healthcare workers has been proven. However, frontline healthcare workers with an adequate supply of personal protective equipment still showed an increased risk of contracting COVID-19. Research on the use of personal protective equipment could provide insight into handling present and future pandemics. OBJECTIVES: This study aims to investigate the impact of the availability, training and correct selection of personal protective equipment on the incidence of SARS-CoV-2 infection or positive suspect cases in healthcare workers during the COVID-19 pandemic in Belgium. DESIGN: This was a prospective cohort study involving Belgian healthcare workers: nurses, nursing aides, and midwives working in hospitals, home care services, and residential care services. METHODS: Respondents were invited from May to July 2020 (period 1) followed by a second time in October 2020 (period 2) to complete a digital survey on personal protective equipment availability, training, personal protective equipment selection, screening ability, COVID-19 testing and status, and symptoms corresponding with the COVID-19 suspect case definition. The main outcome was a composite of COVID-19 status change (from negative to positive) during the study or a positive suspect case definition in period 2. RESULTS: Full data were available for 617 participants. The majority of respondents were nurses (93%) employed in a hospital (83%). In total, 379 respondents provided frontline care for COVID-19 patients (61%) and were questioned on personal protective equipment availability and personal protective equipment selection. Nurses were more likely to select the correct personal protective equipment compared with nursing aides and midwives. Respondents working in residential care settings were least likely to choose personal protective equipment correctly. Of all healthcare workers, 10% tested positive for COVID-19 during the course of the study and a composite outcome was reached in 54% of all respondents. Working experience and sufficient personal protective equipment training showed an inverse relation with the composite outcome. The relationship between personal protective equipment availability and the composite outcome was fully mediated by personal protective equipment training (-0.105 [95% confidence interval -0.211 - -0.020]). CONCLUSIONS: Proper training in personal protective equipment usage is critical to reduce the risk of COVID infection in healthcare workers. During a pandemic, rapid dissemination of video guidelines could improve personal protective equipment knowledge in practitioners. Tweetable abstract: Proper training in personal protective equipment usage is critical to reduce the risk of COVID infection in healthcare workers.

CT-derived measurements of pulmonary blood volume in small vessels and the need for supplemental oxygen in COVID-19 patients.

Throughout the COVID-19 pandemic, a portion of those affected have evolved toward acute hypoxic respiratory failure. Initially, this was hypothesized to result from acute lung injury leading to acute respiratory distress syndrome (ARDS). In previous research, a novel quantitative CT post-processing technique was described to quantify the volume of blood contained within pulmonary blood vessels of a given size. We hypothesized that patients with lower BV5 blood flow would have higher supplemental oxygen needs and less favorable arterial blood gas profiles. From the initial data analysis, 111 hospitalized COVID-19 patients were retrospectively selected based on the availability of CT scans of the lungs with a slice thickness of 1.5 mm or less, as well as PCR-confirmed SARS-CoV2 infection. Three-dimensional (3-D) reconstructions of the lungs and pulmonary vasculature were created. Further analysis was performed on 50 patients. Patients were divided into groups based on their need for oxygen at the time of CT scan acquisition. Eighteen out of 50 patients needed >2 L/min supplemental oxygen and this group demonstrated a significantly lower median percentage of total blood flow in the BV5 vessels compared with the 32 patients who needed <2 L/min supplemental oxygen (41.61% vs. 46.89%, P = 0.023). Both groups had significantly less blood as a proportion in BV5 vessels compared with healthy volunteers. These data are consistent with the hypothesis that reduced blood volume within small (BV5) pulmonary vessels is associated with higher needs for supplemental oxygen and more severe gas exchange anomalies in COVID-19 infections.NEW & NOTEWORTHY This research provides, by using new imaging analysis on CT imaging, an insight into the pathophysiology of patients with COVID-19 infection. By visualizing and quantifying the blood in small vessels in the lung, we can link these results to the clinical need for oxygen in patients with COVID-19 infection.

Role of resilience in healthcare workers' distress and somatization during the COVID-19 pandemic: A cross-sectional study across Flanders, Belgium.

AIM: To evaluate the impact and the possible role of psychological resilience in the COVID-19 pandemic outbreak on healthcare workers' mental and physical well-being in Belgium. DESIGN: This cross-sectional, survey-based study enrolled 1376 healthcare workers across Belgium from 17 April 2020 to 24 April 2020. METHODS: The study sample consisted of direct care workers (nurses and doctors), supporting staff and management staff members. The main outcomes are resilience, distress and somatization. RESULTS: Higher educational level was associated with lower symptoms of distress and somatization. Physicians exhibited the lowest risk of experiencing heightened levels of distress and somatization. Controlling for confounding factors, higher levels of resilience were associated with a 12% reduced chance of increased distress levels and 5% lower chance of increased somatization levels. Our results suggest the potentially buffering role of mental resilience on those working on the frontline during the COVID-19 pandemic outbreak.

Work stress-related problems in physicians in the time of COVID-19.

OBJECTIVES: Healthcare workers in the emergency department are exposed to a wide range of physical and psycho-social risks or hazards in the workplace. The aim of this study was to investigate the impact of exposure to, the occurrence and perceived risks of, and the worry about, occupational hazards among emergency and hospital physicians in the time of COVID. MATERIAL AND METHODS: Based on the review of occupational hazards in emergency physicians, a questionnaire already used and validated in another study, conducted in 2016, was constructed. The questionnaire consisted of both socio-demographic questions and questions regarding the exposure to, the occurrence and perceived risks of, and the worry about, the following occupational hazards: infectious diseases, COVID-19, physical hazards, violence at work, and stressful situations at work that can cause burnout. A total of 497 questionnaires were distributed to Belgian emergency and hospital physicians in April 20-May 26, 2020. RESULTS: Overall, 319 responses (out of 497 questionnaires) were collected, of which 196 were eligible for statistical analysis. Of the respondents, 32% stated to be confronted with violence and 54% to suffer from health problems related to their work. The exposure to, and the occurrence and perceived risks of, occupational hazards and, more specifically, the exposure to COVID-19 (88%) and its occurrence (10%), and also the worry about these hazards, appear to be high in physicians working in the emergency department. The worry about each of these outcomes is predicted by the supposed exposure, occurrence, and perceived risks. CONCLUSIONS: The exposure to, and the occurrence and perceived risks of, physical hazards, violence and burnout are generally high in physicians in the time of COVID-19. Emergency and hospital physicians in Belgium worry the most about the impact of violence, burnout and COVID-19. Int J Occup Med Environ Health. 2021;34(3):373-83.

Vulnerability and Stressors for Burnout Within a Population of Hospital Nurses: A Qualitative Descriptive Study.

BACKGROUND: The multitude of negative consequences of nurse burnout calls for interventions to protect the well-being of the individual nurses, patients, and hospital organizations. However, much is still to be discovered about the development of this complex psychological syndrome. PURPOSE: This study aimed to describe the development of nurse burnout for a population of Flemish hospital nurses while considering vulnerability and situational stressors as indicated by the vulnerability-stress model. METHODS: Ten registered nurses were enlisted for semistructured interviews through purposive sampling. All selected nurses were currently suffering from burnout, showed a burnout risk, or had gone through a burnout in the past. A descriptive thematic analysis was performed with themes inductively emerging from the data. RESULTS: Four main themes emerged: "being passionate about doing well or being good," "teamwork," "manager," and "work and personal circumstances." More specifically, it was the discrepancy between the first individual vulnerability factor and the three situational stressors that led to feelings of stress and burnout. CONCLUSIONS: The essence of the development of nurse burnout was found in the discrepancy between individual vulnerability and situational stressors. Therefore, we recommend burnout prevention to target both factors.
