Undergraduate occupational medicine education in European Medical Schools: better training to meet today's challenges.

BACKGROUND: Occupational medicine (OM) faces considerable challenges today, one of them related to the university training of future physicians considered suboptimal at a global level as it has been pointed out in many studies. The aim of this study is to update the state of OM medical education in European universities. METHODS: Between March and August 2022, an e-mail survey regarding OM training to undergraduate medical students was conducted among OM professors at European universities in 28 countries (n = 347). RESULTS: Of the 347 universities, 53 medical schools from 19 countries responded (response rate = 15.3%). In 89% of cases, OM was taught. The average number of hours per academic year was 24.3, with significant variation within the same country. Lectures were the most popular teaching technique (98%), with a considerable use of modern approaches such as problem-based learning (61%), and e-learning (57%). While occupational diseases and principles of prevention were covered, other subjects such as the environmental impact or collaboration with an OM physician were poorly represented in the educational program. CONCLUSION: According to data, several European medical schools may provide insufficient OM education and training to their students. The education of undergraduate occupational medicine students in European medical schools should be designed to equip them with the knowledge and skills required to meet today's challenges. It is critical that undergraduate OM education in European medical schools be enhanced, harmonized, and standardized.

Precision and Recall of Search Strategies for Identifying Studies on Work-Related Psychosocial Risk Factors in PubMed.

PURPOSE: This study aims to report on the effectiveness of various search strategies and keywords to find studies on work-related psychosocial risk factors (PRF) in the PubMed bibliographic database. METHODS: We first selected by hand-searching 191articles published on PRF and indexed in PubMed. We extracted 30 relevant MeSH terms and 38 additional textwords. We then searched PubMed combining these 68 keywords and 27 general keywords on work-related factors. Among the 2953 articles published in January 2020, we identified 446 articles concerning exposure to PRF, which were gathered in a Gold Standard database. We then computed the Recall, Precision, and Number Needed to Read of each keyword or combination of keywords. RESULTS: Overall, 189 search-words alone or in combination were tested. The highest Recall with a single MeSH term or textword was 43% and 35%, respectively. Subsequently, we developed two different search strings, one optimizing Recall while keeping Precision acceptable (Recall 98.2%, Precision 5.9%, NNR 16.9) and one optimizing Precision while keeping Recall acceptable (Recall 73.1%, Precision 25.5%, NNR 9.7). CONCLUSIONS: No single MeSH term is available to identify relevant studies on PRF in PubMed. Locating these types of studies requires the use of various MeSH and non-MeSH terms in combination to obtain a satisfactory Recall. Nevertheless, enhancing the Recall of search strategies may lead to lower Precision, and higher NNR, although with a non-linear trend. This factor must be taken into consideration when searching PubMed.

Occupational stressors in healthcare workers in France.

OBJECTIVES: To describe psychosocial constraints and mental health of hospital workers, and to identify the psychosocial constraints significantly associated with mental health difficulties, especially in two groups: caregivers and other hospital workers. METHOD: Data about working conditions and health status collected by the Evrest National observatory in 2018-2019 during occupational health consultation were used. Psychosocial constraints and mental health among caregivers, other hospital workers and non-hospital workers were described. RESULTS: There were 1251 hospital workers (843 caregivers, 408 other hospital workers) and 25 129 other workers. Intensity and working time (time pressure, extra working time, missing or shortening a meal), and ethical dilemmas (not having the means to ensure high-quality work, too rapidly handling a procedure that would require more painstaking care) were significantly more reported by the caregivers than by the other hospital workers (50.8% vs 44.2%, 43.4% vs 32.5%, 47.2% vs 17.2%, 21.4% vs 16.4% and 41.5% vs 29.0% respectively). Prevalence of psychological distress was not significantly higher for caregivers (12.3%) than for other hospital workers (12.4%) but was significantly higher than for other workers (7.3%). For caregivers, factors significantly associated with psychological distress were time pressure (Odds Ratio adjusted on sociodemographic factors (OR) = 2.33 CI95% [1.35-4.04]), "difficulties to reconcile private life and work life" (OR = 2.95 [1.54-5.69]), "work not recognized in the professional setting" (OR = 1.89 [1.08-3.31]) and "fear of losing one's job" (OR = 2.98 [1.53-5.8]). For other hospital workers, they were "difficulties to reconcile private life and work life (OR = 2.76 [1.04-7.30]), "insufficient possibilities of mutual aid" (OR = 2.85 [1.24-6.53] and "not having the means to ensure high-quality work" (OR = 3.42 [1.62-7.21]). CONCLUSION: Factors significantly associated with psychological distress were not the same for caregivers and other hospital workers, nor were they the most frequently reported. Detailed description of the constraints according to group of workers could help to develop a high-priority preventive program regarding psychosocial risk factors.

Influence of author's affiliation and funding sources on the results of cohort studies on occupational cancer.

BACKGROUND: Reliability and credibility of research conducted by industry have been questioned, including in the field of occupational health. METHODS: Cohort studies on occupational cancer published between 2000 and 2010 were compared according to their results, their conclusions, their funding, and the affiliation of their authors. RESULTS: Overall, 510 articles were included. Studies published by authors with public affiliation or funded by public grants concluded that their study showed an excess of cancer more frequently (P = 0.01) than studies published by authors with private affiliation or funded by private grants (88% [95%CI = 85-91] vs. 73% [95%CI = 56-88] and 92% [95%CI = 86-97] vs. 71% [95%CI = 57-84], respectively). Discrepancies between statistical results and conclusion occurred more frequently in articles written by authors from the private sector than from the public sector (42% [IC95% = 26-60] vs. 23% [IC95% = 18-26], P = 0.02). CONCLUSIONS: Industry affiliations of authors or industry support of studies are associated with the results of published studies on occupational cancer. The underlying mechanisms warrant further investigation.

Association of occupational exposure with features of systemic sclerosis.

BACKGROUND: Occupational exposure is reported as playing a substantial causative role in systemic sclerosis (SSc). OBJECTIVE: We sought to compare the characteristics of SSc in patients with and without occupational exposure to crystalline silica/solvents. METHODS: In all, 142 patients with SSc were enrolled in this prospective study. An expert committee performed blind evaluation of occupational exposure to crystalline silica/solvents. RESULTS: Patients exposed to crystalline silica more often exhibited: diffuse cutaneous SSc (P = .02), digital ulcers (P = .05), interstitial lung disease (P = .0004), myocardial dysfunction (P = .006), and cancer (P = .06). Patients exposed to solvents more frequently developed: diffuse cutaneous SSc (P = .001), digital ulcers (P = .01), interstitial lung disease (P = .02), myocardial dysfunction (P = .04), and cancer (P = .003); in addition, these patients were more frequently anti-Scl 70 positive and anticentromere negative. Under multivariate analysis, significant factors for SSc associated with exposure to silica/solvents were: male gender (odds ratio 19.31, 95% confidence interval 15.34-69.86), cancer (odds ratio 5.97, 95% confidence interval 1.55-23.01), and digital ulcers (odds ratio 2.42, 95% confidence interval 1.05-5.56). LIMITATIONS: The cohort originated from a single geographic region. CONCLUSION: Occupational exposure to crystalline silica/solvents is correlated with more severe forms of SSc characterized by: diffuse cutaneous involvement, interstitial lung disease, general microangiopathy (digital ulcers and myocardial dysfunction), and association with cancer. Occupational exposure should be systematically checked in all patients with SSc, as exposed patients seem to develop more severe forms of SSc.

[Occupational medicine in France: the current situation in 2024]. / Médecine du travail en France, état des lieux en 2024.

OCCUPATIONAL MEDICINE IN France : THE CURRENT SITUATION IN 2024. Occupational medicine has evolved since its creation in 1946. Occupational medicine services have become Occupational health services (OHS) and medical examination in nowadays only a part of their missions, which include helping the employers to perform risk assessment, patients to stay at work, and implementing health promotion in the workplaces in order to prevent disabilities. To fulfill those missions, OHS can rely on health specialists (occupational physicians and nurses) but also on a wide range of competencies, from toxicologists to ergonomists, and from psychologists to occupational hygiene specialists, all gathered in multidisciplinary teams, leaded by the occupational physician. Optimizing cooperation between general practitioners and occupational health physicians is still needed to improve the worker journey, to facilitate his ability to return to work and to ameliorate his long-term health follow-up according to his previous occupational exposures.

MÉDECINE DU TRAVAIL EN FRANCE, ÉTAT DES LIEUX EN 2024. La médecine du travail a peu à peu évolué, depuis sa création en 1946. Les services médicaux du travail sont devenus des services de prévention et de santé au travail, et le suivi de santé ne représente désormais qu'une partie de leur activité. L'aide à l'évaluation des risques, le maintien en emploi, les actions de promotion de la santé dans une perspective de prévention de la désinsertion professionnelle ont pris une place grandissante. Cela s'est accompagné d'une évolution des compétences au sein de ces services. Outre la compétence santé représentée par le binôme médecin-infirmier, des ergonomes, psychologues et toxicologues sont désormais présents ; ils interviennent en prévention des risques professionnels et constituent des équipes pluridisciplinaires, animées et coordonnées par le médecin du travail. Une meilleure collaboration entre médecin du travail et médecin traitant reste nécessaire pour améliorer le parcours du travailleur, son maintien en emploi et son suivi de santé au long cours en fonction de ses expositions professionnelles passées.

Assessment of search strategies in Medline to identify studies on the impact of long COVID on workability.

Objectives: Studies on the impact of long COVID on work capacity are increasing but are difficult to locate in bibliographic databases, due to the heterogeneity of the terms used to describe this new condition and its consequences. This study aims to report on the effectiveness of different search strategies to find studies on the impact of long COVID on work participation in PubMed and to create validated search strings. Methods: We searched PubMed for articles published on Long COVID and including information about work. Relevant articles were identified and their reference lists were screened. Occupational health journals were manually scanned to identify articles that could have been missed. A total of 885 articles potentially relevant were collected and 120 were finally included in a gold standard database. Recall, Precision, and Number Needed to Read (NNR) of various keywords or combinations of keywords were assessed. Results: Overall, 123 search-words alone or in combination were tested. The highest Recalls with a single MeSH term or textword were 23 and 90%, respectively. Two different search strings were developed, one optimizing Recall while keeping Precision acceptable (Recall 98.3%, Precision 15.9%, NNR 6.3) and one optimizing Precision while keeping Recall acceptable (Recall 90.8%, Precision 26.1%, NNR 3.8). Conclusions: No single MeSH term allows to find all relevant studies on the impact of long COVID on work ability in PubMed. The use of various MeSH and non-MeSH terms in combination is required to recover such studies without being overwhelmed by irrelevant articles.

Is the coverage of Google Scholar enough to be used alone for systematic reviews.

BACKGROUND: In searches for clinical trials and systematic reviews, it is said that Google Scholar (GS) should never be used in isolation, but in addition to PubMed, Cochrane, and other trusted sources of information. We therefore performed a study to assess the coverage of GS specifically for the studies included in systematic reviews and evaluate if GS was sensitive enough to be used alone for systematic reviews. METHODS: All the original studies included in 29 systematic reviews published in the Cochrane Database Syst Rev or in the JAMA in 2009 were gathered in a gold standard database. GS was searched for all these studies one by one to assess the percentage of studies which could have been identified by searching only GS. RESULTS: All the 738 original studies included in the gold standard database were retrieved in GS (100%). CONCLUSION: The coverage of GS for the studies included in the systematic reviews is 100%. If the authors of the 29 systematic reviews had used only GS, no reference would have been missed. With some improvement in the research options, to increase its precision, GS could become the leading bibliographic database in medicine and could be used alone for systematic reviews.
