Sleep disturbances and psychological well-being among military medical doctors of the Swiss Armed Forces: study protocol, rationale and development of a cross-sectional and longitudinal interventional study

Background

Compared to civilians and non-medical personnel, military medical doctors are at increased risk for sleep disturbances and impaired psychological well-being. Despite their responsibility and workload, no research has examined sleep disturbances and psychological well-being among the medical doctors (MDs) of the Swiss Armed Forces (SAF). Thus, the aims of the proposed study are (1) to conduct a cross-sectional study (labeled 'Survey-Study 1') of sleep disturbances and psychological well-being among MDs of the SAF; (2) to identify MDs who report sleep disturbances (insomnia severity index >8), along with low psychological well-being such as symptoms of depression, anxiety and stress, but also emotion regulation, concentration, social life, strengths and difficulties, and mental toughness both in the private/professional and military context and (3) to offer those MDs with sleep disturbances an evidence-based and standardized online interventional group program of cognitive behavioral therapy for insomnia (eCBTi) over a time lapse of 6 weeks (labeled 'Intervention-Study 2').

Method

All MDs serving in the SAF (N = 480) will be contacted via the SAF-secured communication system to participate in a cross-sectional survey of sleep disturbances and psychological well-being ('Survey-Study 1'). Those who consent will be provided a link to a secure online survey that assesses sleep disturbances and psychological well-being (depression, anxiety, stress, coping), including current working conditions, job-related quality of life, mental toughness, social context, family/couple functioning, substance use, and physical activity patterns. Baseline data will be screened to identify those MDs who report sleep disturbances (insomnia severity index >8); they will be re-contacted, consented, and randomly assigned either to the eCBTi or the active control condition (ACC) ('Intervention-Study 2'). Individuals in the intervention condition will participate in an online standardized and evidence-based group intervention program of cognitive behavioral therapy for insomnia (eCBTi; once the week for six consecutive weeks; 60-70 min duration/session). Participants in the ACC will participate in an online group counseling (once the week for six consecutive weeks; 60-70 min duration/session), though, the ACC is not intended as a bona fide psychotherapeutic intervention. At the beginning of the intervention (baseline), at week 3, and at week 6 (post-intervention) participants complete a series of self-rating questionnaires as for the Survey-Study 1, though with additional questionnaires covering sleep-related cognitions, experiential avoidance, and dimensions of self-awareness.

Expected outcomes

Survey-Study 1: We expect to describe the prevalence rates of, and the associations between sleep disturbances (insomnia (sleep quality); sleep onset latency (SOL); awakenings after sleep onset (WASO)) and psychological well-being among MDs of the SAF; we further expect to identify specific dimensions of psychological well-being, which might be rather associated or non-associated with sleep disturbances.Intervention-Study 2: We expect several significant condition-by-time-interactions. Such that participants in the eCBTi will report significantly greater improvement in sleep disturbances, symptoms of depression, anxiety, stress reduction both at work and at home (family related stress), and an improvement in the overall quality of life as compared to the ACC over the period of the study.

Conclusion

The study offers the opportunity to understand the prevalence of sleep disturbances, including factors of psychological well-being among MDs of the SAF. Further, based on the results of the Intervention-Study 2, and if supported, eCBTi may be a promising method to address sleep disturbances and psychological well-being among the specific context of MDs in the SAF.

Hydration and meal habits of physicians and medical learners: a literature review

PURPOSE

Nutrition and hydration are important components of physician and medical learner well-being; meal-skipping and insufficient hydration are known to negatively impact cognition. Existing data on these phenomena are sparse and rarely considered together; furthermore, there is a lack of literature on interventions to address these problems. We therefore aimed to characterize existing literature on this topic.

METHODS

We conducted a literature review of existing literature on the prevalence of and reasons for meal-skipping and insufficient hydration in physicians and medical learners.

RESULTS

Reported prevalences varied widely, as did the ways in which the data were collected. Reasons for meal-skipping and insufficient hydration are less studied, but a lack of time is the most commonly reported reason, among a variety of other barriers.

CONCLUSION

Further research is required to better characterize the prevalences and reasons for meal-skipping in physicians and medical learners. By consolidating the state of current knowledge on this topic in this work, we establish the groundwork for future studies and allow intervention studies to be based on a broader data set.

Nutritional Wellness for the Busy Health Care Provider: Small Everyday Wins

When describing health care provider wellness, diet and nutrition are typically not addressed. This, in combination with the lack of decent food and diet resources typically available to the typically busy health care provider, exposes a significant gap in the road to advancing clinician wellness. This article aims to describe the relationship between nutrition and well-being, and potential barriers to optimal nutrition encountered by health care providers in the workplace. Readily available and practical strategies to improve physician diet and nutrition include: mindful eating practices, home meal preparation, food journaling, and mobile applications. From an organizational level, once physicians are making more informed food choices it is the hospital's responsibility to make nutritional options available in the workplace.

A Cross-Sectional Examination of the Association Between Social Media Use and Sleep Among a Sample of U.S. Army Soldiers

INTRODUCTION

In the United States (U.S.), approximately 35% of adults sleep less than 7 hours per night. The relationship between social media use and insufficient sleep has not thoroughly been examined among adults. The purpose of this study was to determine if social media use is associated with insufficient sleep among a sample of U.S. Army Soldiers.

METHODS

This study surveyed 9,052 U.S. Soldiers in 2018 via a self-administered online questionnaire. Using multivariable logistic regression, we examined the association between social media use (<38 hours vs. ≥38 hours per week) and insufficient sleep, controlling for demographic and behavioral covariates.

RESULTS

Overall, 54.9% of Soldiers reported insufficient sleep. There was no significant relationship between excessive social media use and insufficient sleep in the multivariable logistic regression (OR: 1.03; CI: 0.87-1.23). The covariates of sex, race/ethnicity, rank, hazardous alcohol consumption, anxiety, and depression were significantly associated with insufficient sleep. Soldiers who reported symptoms of anxiety were more than twice as likely (OR: 2.11; CI: 1.65-2.70) to report insufficient sleep than Soldiers without signs of anxiety. Additionally, Soldiers who reported depressive symptoms were 85% (OR: 1.85; CI: 1.44-2.37) more likely to experience insufficient sleep than Soldiers without signs of depression.

CONCLUSION

Sufficient sleep is essential to ensuring mission readiness and preventing accidental morbidity and mortality among Soldiers. The findings of this analysis do not suggest a link between extended social media use and insufficient sleep. However, though previously uninvestigated, Soldiers reporting symptoms of anxiety and depression were more likely to experience insufficient sleep compared to unafflicted Soldiers. Therefore developing a culture that encourages Soldiers to seek necessary behavioral health screening and care could be a key primary strategy to promote adequate sleep.

Association of Burnout, Professional Fulfillment, and Self-care Practices of Physician Leaders With Their Independently Rated Leadership Effectiveness

IMPORTANCE

Although leadership behavior of physician supervisors is associated with the occupational well-being of the physicians they supervise, the factors associated with leadership behaviors are poorly understood.

OBJECTIVE

To evaluate the associations between burnout, professional fulfillment, and self-care practices of physician leaders and their independently assessed leadership behavior scores.

DESIGN, SETTING, AND PARTICIPANTS

This survey study of physicians and physician leaders at Stanford University School of Medicine (n = 1924) was conducted from April 1 to May 13, 2019. The survey included assessments of professional fulfillment, self-valuation, sleep-related impairment, and burnout. Physicians also rated the leadership behaviors of their immediate physician supervisors using a standardized assessment. Leaders' personal well-being metrics were paired with their leadership behavior scores as rated by the physicians they supervised. All assessment scores were converted to a standardized scale (range, 0-10). Data were analyzed from October 20, 2019, to March 10, 2020.

MAIN OUTCOMES AND MEASURES

Association between leaders' own well-being scores and their independently assessed leadership behavior.

RESULTS

Of 1924 physicians invited to participate, 1285 (66.8%) returned surveys, including 67 of 117 physician leaders (57.3%). Among these respondents, 651 (50.7%) were women and 729 (56.7%) were 40 years or older. Among the 67 leaders, 57 (85.1%) had their leadership behaviors evaluated by at least 5 physicians (median, 11 [interquartile range, 9-15]) they supervised. Overall, 9.8% of the variation in leaders' aggregate leadership behavior scores was associated with their own degree of burnout. In models adjusted for age and sex, each 1-point increase in burnout score of the leaders was associated with a 0.19-point decrement in leadership behavior score (β = -0.19; 95% CI, -0.35 to -0.03; P = .02), whereas each 1-point increase in their professional fulfillment and self-valuation scores was associated with a 0.13-point (β = 0.13; 95% CI, 0.01-0.26; P = .03) and 0.15-point (β = 0.15; 95% CI, 0.02-0.29; P = .03) increase in leadership behavior score, respectively. Each 1-point increase in leaders' sleep-related impairment was associated with a 0.15-point increment in sleep-related impairment among those they supervised (β = 0.15; 95% CI, 0.02-0.29; P = .03). The associations between leaders' well-being scores in other dimensions and the corresponding well-being measures of those they supervised were not significant.

CONCLUSIONS AND RELEVANCE

In this survey study, burnout, professional fulfillment, and self-care practices of physician leaders were associated with their independently assessed leadership effectiveness. Training, skill building, and support to improve leader well-being should be considered a dimension of leadership development rather than simply a dimension of self-care.

Organizational strategies to reduce physician burnout and improve professional fulfillment

Burnout is highly prevalent among physicians and has been associated with negative outcomes for physicians, patients, staff, and health-care organizations. Reducing physician burnout and increasing physician well-being is a priority. Systematic reviews suggest that organization-based interventions are more effective in reducing physician burnout than interventions targeted at individual physicians. This consensus review by leaders in the field across multiple institutions presents emerging trends and exemplary evidence-based strategies to improve professional fulfillment and reduce physician burnout using Stanford's tripartite model of physician professional fulfillment as an organizing framework: practice efficiency, culture, and personal resilience to support physician well-being. These strategies include leadership traits, latitude of control and autonomy, collegiality, diversity, teamwork, top-of-license workflows, electronic health record (EHR) usability, peer support, confidential mental health services, work-life integration and reducing barriers to practicing a healthy lifestyle. The review concludes with evidence-based recommendations on establishing an effective physician wellness program.

The Mismatch of Nutrition and Lifestyle Beliefs and Actions Among Physicians: A Wake-Up Call

Background. There is a notable lack of education on nutrition and physical activity guidelines in medical schools and postgraduate training. The purpose of this study is to assess the nutrition and exercise knowledge and personal health behaviors of physicians in the Department of Medicine at a large academic center. Methods. We conducted a survey study in the Department of Medicine at the University of Florida in 2018. The survey instrument included questions on demographics, medical comorbidities, baseline perception of health and fitness, and knowledge of nutrition concepts. The Duke Activity Status Index assessed activity/functional capacity and the validated 14-point Mediterranean Diet Survey evaluated dietary preferences. Data were analyzed using descriptive statistics and the χ² test was used to perform comparisons between groups. Statistical significance was determined at P < .05. Results. Out of 331 eligible physicians, 303 (92%) participated in the study. While all respondents agreed that eating well is important for health, less than a fourth followed facets of a plant-based Mediterranean diet. Only 25% correctly identified the American Heart Association recommended number of fruit and vegetable servings per day and fewer still (20%) were aware of the recommended daily added sugar limit for adults. Forty-six percent knew the American Heart Association physical activity recommendations and 52% reported more than 3 hours of personal weekly exercise. Reported fruit and vegetable consumption correlated with perceived level of importance of nutrition as well as nutrition knowledge. Forty percent of physicians (102/253) who considered nutrition at least somewhat important reported a minimum of 2 vegetable and 3 fruit servings per day, compared with 7% (3/44) of those who considered nutrition less important ("neutral," "not important," or "important, but I don't have the time to focus on it right now"; P < .0001). Conclusions. This study highlights the need for significant improvement in education of physicians about nutrition and physical activity and need for physicians to focus on good personal health behaviors, which may potentially improve with better education.
