Work stress and burnout among emergency physicians: a systematic review of last 10 years of research

AIM OF THE STUDY

First, to provide a synthesis and analysis of available scientific literature regarding the level of work stress and burnout among emergency physicians. Second, to identify the effect of the specific work situation-related factors.

METHODS

A systematic search was performed in NCBI PubMed and Embase. Comparative primary studies, both systematic review and cross-sectional, quantifying burnout in emergency physicians were included. Only studies published between 2011 and 2022 were retained. Synonym sets were compiled for the search key for 'burnout & stress', 'emergency', 'physician' and 'burnout & posttraumatic stress disorder'.

RESULTS

Thirty-five papers were retained for further research. Emergency physicians scored significantly higher for all dimensions of burnout compared to other healthcare professions. Significant correlations for burnout were found with work characteristic and organizational factors. Critical incidents and aggression were identified as the most important acute work characteristics and organizational factors impacting emergency physician's mental wellbeing including the development of posttraumatic stress disorder. Moreover, personal factors such as age, personality, and coping strategies also play an important role in the development of burnout as well as work-related trauma.

CONCLUSION

Available studies show that emergency physicians report higher scores of emotional exhaustion and depersonalization when compared to other healthcare professionals. Work characteristics contribute to this, but work-related traumatic incidents and aggression are important determinants. Personal characteristics such as age, personality type D, previous experiences and coping strategies seem to be determining factors likewise. Emergency physicians showed a high risk for developing burnout and work stress-related problems.

Gender-specific characteristics of alcohol use in community-dwelling older adults in Belgium

OBJECTIVES

Gender has been identified as an important social determinant for health. This study investigates gender-specific characteristics for alcohol use (AU) among community-dwelling older adults.

METHODS

This is a retrospective cross-sectional study in 1.406 community-dwelling older adults. We used standardized questionnaires to collect self-reported data on alcohol use behavior, mental health, drinking motives and resilience by using, respectively, the Alcohol Use Identification Test (AUDIT), the Brief Symptom Inventory (BSI), the Drinking Motives Questionnaire (DMQ), and the Connor-Davidson Resilience Scale (CD-RISC). Multiple linear regression was used to identify the joint contribution of those factors on AU. Hierarchical regression was used to investigate the influence of the interaction between gender and those factors on AU.

RESULTS

Linear regression analyses showed different associations with AU in men and women. Hierarchical regression analyses showed that gender presented a two-way interaction effect with enhancement and anxiety variables related to AU.

CONCLUSIONS

Different characteristics were found as predictors for AU among older men and women.

CLINICAL IMPLICATIONS

Clinicians and health-care providers should be aware of these differences in order to provide tailored screening and intervention programs to reduce AU in older adults.

Resilience, depression and anxiety and hazardous alcohol use behaviour among community dwelling older adults

INTRODUCTION

We examined the psychometric properties of the CD-RISC, including factor structure. Secondly, we examined if resilience factors moderate the association between negative affect and hazardous alcohol use.

METHOD

The sample population consisted of 1,368 community-dwelling older adults. We used standardized questionnaires to collect self-reported data on alcohol use behaviour, depression and anxiety and resilience by using respectively the Alcohol Use Identification Test (AUDIT), the Brief Symptom Inventory (BSI) and the Connor-Davidson Resilience Scale (CD-RISC).

RESULTS

Of the total sample (N 1.368), 80.1% reported using alcohol. The total sample and the drinking sample reported, respectively, a mean of 65.75 (SD 15.40) and 65.79 (SD 15.90) on the CD-RISC. Concerning the CD-RISC, exploratory factor analysis presents four factors of which three with a good reliability. Moderation analyses reflects that older adults with higher levels of resilient characteristics didn't report an association between negative affect and hazardous drinking. Alternatively, low resilient older adults did report an positive and significant association between negative affect and hazardous drinking.

CONCLUSION

The CD-RISC appeared to be a reliable instrument, containing three factors. In our sample, high resilience moderated the association between negative affect and hazardous drinking and may serve as a buffer against hazardous drinking.

The Risk of Malnutrition in Community-Living Elderly on Admission to Hospital for Major Surgery

BACKGROUND

With prevalence rates varying from 10 to 60%, malnutrition in acute hospitals has been acknowledged as a persistent problem in older adults worldwide. This publication is to describe the nutritional condition and associated risk factors of malnutrition in free living elderly on admission to the hospital for major elective surgery.

METHODS

A cross sectional, multi-center study in eight surgical wards in three Belgian hospitals. A total of 204 free living elderly, aged 74.8 ± 6.6 years (Mean ± SD), on admission to the hospital for major elective surgery and requiring at least 3 days of hospitalization, were consecutively recruited to the study. The nutritional status was assessed on admission and before surgery using the recommended NRS-2002. Data on possible associated factors were collected during post-operative stay using a structured questionnaire.

RESULTS

A total of 107 patients (51.4%) were at high risk of malnutrition. In patients older than 70 years (n 150) the risk of malnutrition increased up to 66%. None of the included patients reported preoperative referral to a dietician or nutritional advice nor any prescribed preoperative nutritional supplement. In a multivariate regression analysis it appeared that none of the possible associated factors were significantly associated with malnutrition.

CONCLUSIONS

This study confirms the high risk of malnutrition in community living elderly on admission to hospital for elective surgery. According to the NRS-2002 these patients might benefit from nutritional support. However, it appears that nutritional support is not yet commonly implemented in preoperative care for this population at risk.

Mechanism of edge localized mode mitigation by resonant magnetic perturbations

A possible mechanism of edge localized modes (ELMs) mitigation by resonant magnetic perturbations (RMPs) is proposed based on the results of nonlinear resistive magnetohydrodynamic modeling using the jorek code, realistic JET-like plasma parameters and an RMP spectrum of JET error-field correction coils (EFCC) with a main toroidal number n=2 were used in the simulations. Without RMPs, a large ELM relaxation is obtained mainly due to the most unstable medium-n ballooning mode. The externally imposed RMP drives nonlinearly the modes coupled to n=2 RMP which produce small multimode relaxations, mitigated ELMs. The modes driven by RMPs exhibit a tearinglike structure and produce additional islands. Mitigated ELMs deposit energy into the divertor mainly in the structures ("footprints") created by n=2 RMPs, however, slightly modulated by other nonlinearly driven even harmonics. The divertor power flux during a ELM phase mitigated by RMPs is reduced almost by a factor of 10. The mechanism of ELM mitigation by RMPs proposed here reproduces generic features of high collisionality RMP experiments, where large ELMs are replaced by small, much more frequent ELMs or magnetic turbulence. Total ELM suppression was also demonstrated in modeling at higher RMP amplitude.

Clinical and immunological effects of immunotherapy with alum-absorbed grass allergoid in grass-pollen-induced hay fever

A double-blind, placebo-controlled study of immunotherapy was conducted in 19 patients with grass-pollen hay fever to evaluate the efficacy and safety of a formalinized depot grass allergoid. The patients were assessed before and during IT by clinical (symptom-medication scores during the grass- pollen season, specific nasal and skin reactivity) and immunological (specific IgE, IgG, IgG1 and IgG4 antibodies) parameters. High doses of grass allergoid, corresponding to a cumulative pre-seasonal dosage of 46,050 PNU, were administered, with only one systemic reaction. The actively treated patients had significantly lower symptom-medication scores than placebo (p less than 0.01) during the month of May and showed a significant decrease in specific skin (p less than 0.01) and nasal (p less than 0.05) reactivity, and a significant early increase in specific IgE (p less than 0.01), IgG (p less than 0.0005), IgG1 (p less than 0.001) and IgG4 (p less than 0.05), with a subsequent decrease of IgE and IgG1. No differences were detected in any of these parameters in the placebo group. A correlation was found between high IgG4/IgG1 ratio and the specific skin reactivity decrease (r = 0.691, p less than 0.05), whereas a high IgG4/IgG1 ratio was associated with higher symptom-medication scores (r = 0.654, p less than 0.05). Possible explanations of these apparent discrepancies are proposed.
