ObjectiveTo estimate the prospective relationships between exposure to psychosocial risks dimensions included in the COPSOQ-Istas21 and the deterioration of general and mental health and sleep problems among workers residing in Spain.MethodCohort whose baseline corresponds to the 2016 Psychosocial Risks Survey with a new measurement after one year.ResultsSocial capital and interpersonal relations and leadership dimensions, as well as work?life conflict, were related to all health variables. Dimensions of work organization and job contents did it especially with the mental health, the quantitative demands with the general health and the emotional ones with the mental health. The dimensions related to job insecurity did not show relationships with health.ConclusionsThe results obtained reinforce the role of the COPSOQ-Istas21 as a useful instrument for the evaluation and prevention of psychosocial risks at work.  相似文献

BackgroundObstructive sleep apnea–hypopnea syndrome (OSAHS) is present in 80% of patients evaluated for bariatric surgery (BS). Extensive evaluation is not widely available, but treatment is mandatory for severe cases. The Snore, Tiredness, Observed apneas and Pressure - Body mass index, Age, Neck circumference and Gender (STOP-Bang) and Epworth questionnaires and neck-to-height ratio (NHtR) are accessible clinical tools to screen for sleep and metabolic disturbances, but their utility to detect severe OSAHS in patients with severe obesity has not been determined.ObjectivesTo evaluate the cutoff point of those clinical tools that may predict severe OSAHS, confirmed by polysomnography in patients referred for BS.SettingTertiary referral center in Mexico City.MethodsWe applied the STOP-Bang and Epworth questionnaires, evaluated anthropometric characteristics, and collected samples for arterial gasometry and metabolic parameters from 68 patients with severe obesity, who were then referred for polysomnography before their evaluation for BS.ResultsOf the 68 patients participating in the study, 67.7% were female, with a median age of 43 years (35–49 years) and a body mass index (BMI) of 45.5 kg/m2 (42.4–50.9 kg/m2; 28.3% had a BMI ≥ 50 kg/m2). A STOP-Bang cutoff >5 points had a sensitivity of 60% and specificity of 90% for detecting severe OSAHS (area under the curve [AUC] = .962); meanwhile, an NHtR >.25 had a sensitivity of 90% and specificity of 52.5% (AUC = .759). The Epworth scale score >11 points had a sensitivity of 57.1% and specificity of 83.3% (AUC = .802).ConclusionClinical data may be useful to detect severe sleep apnea in high-risk populations, allowing for rapid referral and better use of resources.  相似文献

BackgroundDespite the promotion of international osteopathic recommendations and registration guidelines, relational competencies and patient education practices present a challenge in the clinical setting due to lack of training. In France, the latest national osteopathic standards for education and practice defined a relational competency that includes patient education. Little is known about its integration in curricula and how French osteopathic practitioners are subsequently trained for relational competency.ObjectiveTo determine teaching, learning, and assessment methods related to relational competency in French initial osteopathic training programs and identify the role of patient education in this relational competency.MethodsAn online questionnaire was designed and sent to all initial training institutes in France (n = 28). Eight institutes answered the survey.ResultsThe relational competencies appeared in various courses, enhanced by clinical learning. However, the courses were not specific to this competency and the volume of hours was relatively low. Patient education was seen as part of relational competency but was poorly implemented. This competency-based approach is still considered an emerging practice in these institutes.ConclusionsThere is a misalignment among intended learning outcomes, teaching, and assessment. Current educational practices are not sufficient to support relational competency, specifically regarding patient education. Further research is needed on how French standards are understood, how they are assimilated by educators, and how they are translated into educational practice. In addition, the adequacy of educators' training for effective implementation of the competency-based approach should be questioned.  相似文献

AimsTo validate a translated and culturally adapted version of the Morisky Medication Adherence Scale for use in Spanish population, and to examine the psychometric properties of this scale in patients with type 2 diabetes mellitus in Spain.DesignThis cross-sectional study was conducted in a single university hospital in Spain. Patients diagnosed with type 2 diabetes mellitus at least 1 year before inclusion, being treated with anti-diabetic medication were included.InterventionWe used the Spanish version of the scale to measure treatment adherence.Principal measurementsthree level categorical scale is broken down into low adherence (score of <6), medium adherence (score of 6 to <8) and high adherence (score of 8). To validate the questionnaire, we measured internal consistency through Cronbach's α, confirmed construct validity through an exploratory principal component analysis and assessed test–retest reliability.Results232 patients met the inclusion criteria. The Cronbach's α coefficient was 0.40 (95% CI 0.28–0.52). The exploratory principal component analysis showed three components. The intraclass correlation coefficient was 0.718 (95% CI 0.564–0.823).Conclusionsthe Spanish version of the Morisky Medication Adherence scale showed low internal consistency, the exploratory factor analysis identified three dimensions, and the test–retest reliability was acceptable, therefore, psychometric properties of MMAS-8 are not suitable for measuring medication adherence in type 2 diabetes mellitus patients from Spain.  相似文献

Isolation and loneliness have become buzz words when discussing older adults during the coronavirus disease pandemic; yet, these are age-old problems. Both have been studied extensively, yet there currently is no rapid or succinct tool that can be used in the emergency department to screen for either, or a consensus of evidence-based ways to correct these issues. This is of concern because both loneliness and social isolation have been linked to poor health. Poor health, in turn, can lead to worse isolation and loneliness. These health problems may lead to the older adult seeking care in the emergency department where screening and initial treatment could be initiated. Suggestions for questions that emergency nurses can ask to identify an older adult who is lonely or suffers from social isolation, as well as steps to consider when encountering the older adult with complaints of loneliness and/or social isolation, are provided, with the realization that these are only the first steps of many that would need to be taken. The purpose of this article is to bring forward updated information that discusses loneliness and social isolation in older adults, a timely priority during the coronavirus disease pandemic and often listed as a factor in older adult deaths. A review of relevant screening tools for use in the emergency department are provided.  相似文献

BackgroundIncreasing prevalence of overweight and obesity represents a global pandemic. As the largest occupational group in international healthcare systems nurses are at the forefront of health promotion to address this pandemic. However, nurses own health behaviours are known to influence the extent to which they engage in health promotion and the public's confidence in advice offered. Estimating the prevalence of overweight and obesity among nurses is therefore important. However, to date, prevalence estimates have been based on non-representative samples and internationally no studies have compared prevalence of overweight and obesity among nurses to other healthcare professionals using representative data.ObjectivesTo estimate overweight and obesity prevalence among nurses in Scotland, and compare to other healthcare professionals and those working in non-heath related occupations.DesignCross-sectional study using a nationally representative sample of five aggregated annual rounds (2008–2012) of the Scottish Health Survey.SettingScotland.Participants13,483 adults aged 17–65 indicating they had worked in the past 4 weeks, classified in four occupational groups: nurses (n = 411), other healthcare professionals (n = 320), unqualified care staff (n = 685), and individuals employed in non-health related occupations (n = 12,067).Main outcome measuresPrevalence of overweight and obesity defined as Body Mass Index  25.0.MethodsEstimates of overweight and obesity prevalence in each occupational group were calculated with 95% confidence intervals (CI). A logistic regression model was then built to compare the odds of being overweight or obese with not being overweight or obese for nurses in comparison to the other occupational categories. Data were analysed using SAS 9.1.3.Results69.1% (95% CI 64.6, 73.6) of Scottish nurses were overweight or obese. Prevalence of overweight and obesity was higher in nurses than other healthcare professionals (51.3%, CI 45.8, 56.7), unqualified care staff (68.5%, CI 65.0, 72.0) and those in non-health related occupations (68.9%, CI 68.1, 69.7). A logistic regression model adjusted for socio-demographic composition indicated that, compared to nurses, the odds of being overweight or obese was statistically significantly lower for other healthcare professionals (Odds Ratio [OR] 0.45, CI 0.33, 0.61) and those in non-health related occupations (OR 0.78, CI 0.62, 0.97).ConclusionsPrevalence of overweight and obesity among Scottish nurses is worryingly high, and significantly higher than those in other healthcare professionals and non-health related occupations. High prevalence of overweight and obesity potentially harms nurses’ own health and hampers the effectiveness of nurses’ health promotion role. Interventions are therefore urgently required to address overweight and obesity among the Scottish nursing workforce.  相似文献
