The impact of time-restricted eating on health-related quality of life: a systematic literature review.

Time-restricted eating (TRE) is a novel dietary intervention shown to facilitate weight loss and improve metabolic health. However, like any dietary intervention, long-term success largely depends on individual adherence, which can be influenced by whether the intervention impacts the individual's health-related quality of life (HR-QoL). Despite the growing body of research investigating TRE as a dietary approach and its potential impact on HR-QoL in adults, to date there has been no systematic review to summarize these findings. To examine the impact of TRE on HR-QoL in adults. All randomized controlled trials, pre-post and pilot/feasibility studies were searched in PubMed, EMBASE via Ovid, CINAHL, Cochrane Library, and PsycINFO via Ovid until March 20, 2023. Two researchers were involved in the screening and paper selection process. A single researcher extracted all relevant data from eligible studies. Overall, 10 studies were eligible for inclusion in this systematic review. Four studies reported improvements in overall HR-QoL scores among participants with type 2 diabetes, middle-aged women with obesity, generally healthy adults, and generally healthy adult employees. Three studies reported significant and nonsignificant improvements in some domains of HR-QoL assessment tools among overweight, sedentary older adults, overweight or obese adults, and 24-hour shift workers. No studies reported that TRE adversely affected HR-QoL. Improvements in HR-QoL appeared to occur primarily at 12 weeks/3 months. There was no clear relationship between HR-QoL scores and TRE protocol, additional study outcomes, participant health status, age, or adherence. Although further research is required to elucidate the impact of TRE on HR-QoL, the findings reveal that no studies show that TRE adversely affects HR-QoL.

Frontiers in Operations: Valuing Nursing Productivity in Emergency Departments.

We quantify the increase in productivity in emergency departments (ED) from increasing nurse staff. We then estimate the associated revenue gains for the hospital and the associated welfare gains for society. The United States is over a decade into the worst nursing shortage crisis in history, fueled by chronic under-investment. To demonstrate to hospital managers and policymakers the benefits of investing in nursing, we clarify the positive downstream effects of doing so in the ED setting. We use a high-resolution data set of patient visits to the ED of a major U.S. academic hospital. Time-dependent hazard estimation methods (nonparametric and parametric) are used to study how the realtime service speed of a patient varies with the state of the ED, including the time-varying workloads of the assigned nurse. A counterfactual simulation is used to estimate the gains from increasing nurse staff in the ED. We find that lightening a nurse's workload by one patient is associated with a 14% service speedup for every patient under the nurse's care. Simulation studies suggest that adding one more nurse to the busiest 12-hour shift of each day can shorten stays and avert $160,000 in lost patient wages per 10,000 visits. The reduction in service times also frees up capacity for treating more patients and generate $470,000 in additional net revenues for the hospital per 10,000 visits. Extensive sensitivity analyses suggest that our key message-investing in nursing will more than pay for itself-is likely to hold across a wide range of EDs. In determining whether to invest in more nursing resources, hospital managers need to look beyond whether payer reimbursements alone are sufficient to cover the upfront costs, to also account for the resulting downstream benefits.

Sleep quality according to chronotype in nurses working 8-hour shifts.

To date, studies have been focused on sleep disturbances of nurses working during night shifts. There is a lack of understanding regarding the sleep quality of nurses working in the rapid rotation system for each type of shift work. To determine the relationship between chronotype and sleep quality according to shift type (i.e. day, evening and night shifts) in nurses working 8-hour rotating shifts. A cross-sectional, descriptive study was conducted from two tertiary hospitals in South Korea from December 2021 to September 2022, including nurses working 8-hour rotating shifts (N = 74). They completed questionnaires to measure general, occupational and sleep-related characteristics, chronotype, insomnia severity and daytime sleepiness. Additionally, sleep parameters were collected from actigraphy and sleep diaries for 7 days. A total of 64% of nurses had an evening chronotype and 37% of nurses had an intermediate chronotype. Nurses had significantly less total sleep time and worsened sleep latency and efficiency during the day shift compared to other shift types. Compared to nurses with an intermediate chronotype, those with an evening chronotype had poorer sleep quality during day shift work. Strategies to enhance nurses' sleep quality during day shifts should consider a two-level approach: individual approaches, such as improving sleep hygiene, and administrative approaches, such as establishing a chronotype-based shift system for scheduling.

Job Satisfaction, Occupational Stress, and Attitudes Toward Older Adults Among Nursing Home Employees

Aim: The quality of care provided in long-term nursing homes is affected by numerous factors such as ageism and the employees’ job satisfaction and occupational stress levels. This study was aimed to investigate nursing home employees’ occupational stress, job satisfaction, and attitudes toward older adults. Materials and Methods: This research was a descriptive study. The study population comprised five nursing homes that agreed to participate in the study. Workers were included in the study regardless of their position. A total of 107 employees were included. Data were collected using a personal information form, the Ageism Attitude Scale, Perceived Job Stress Scale, and Minnesota Job Satisfaction Questionnaire. Results: The mean age of the participants was 39.9 years and their mean duration of employment was 4.5 years. Of the workers, 61.7% were female, 31.8% were university graduates, 41.1% were care staff, 50.5% worked 8-hour shifts, 74.8% were satisfied with their job, and 80.4% were not considering job departure. There was a significant moderate negative correlation between occupational stress and overall job satisfaction (p

Professional attractiveness among long-term care workers in nursing homes in China: a cross-sectional study

BackgroundThe population aging trend and the shortage of elderly care workers require the long-term care profession to become more attractive. However, the professional attractiveness among long-term care workers has yet to be extensively studied. This study aims to identify the factors that influence the attractiveness of the long-term care profession for nursing home (NH) care workers..MethodsA cross-sectional study was conducted in more than 50 NHs. Perception of professional attractiveness among long-term care workers and potential associated factors were measured using the Attractive Work Questionnaire (AWQ) and structural instruments including the Fraboni Scale of Ageism (FSA) and the Maslach Burnout Inventory (MBI). A multiple linear regression method was employed to explore the influence of potential independent variables on professional attractiveness.ResultsThe overall response rate was 99%. The results showed the score of professional attractiveness (185.37 ± 20.034), as well as the scores of each component (99.26 ± 11.258 for work condition, 30.13 ± 3.583 for work content, and 55.99 ± 7.074 for job satisfaction). Findings of multiple linear regression analysis indicated that age(β = 0.129, p<.05), years of work(β = 0.156, p<.05), 12-hour shifts(β = 0.185, p<.05), and training times per year(β = 0.148, p<.05) positively associated with long-term care workers perceived professional attractiveness. Whereas only ageism(β=-0.267, p<.05) significantly and negatively influenced professional attractiveness.ConclusionsThe perceived professional attractiveness of long-term care workers in NHs was acceptable. Age, years of work, shifts, training opportunities, and ageism contributed to the professional attractiveness of nursing home care workers in China. Target intervention measures should be taken to enhance the attractiveness of long-term care careers so as to avoid the shortage of long-term care workers.

The Influence of Emergency Call Volume on Occupational Workload and Sleep Quality in Urban Firefighters.

The aim of the study is to determine the impact of emergency call volume on exertion, autonomic activity, and sleep among urban structural firefighters. Thirty-four firefighters wore a wrist-based monitor to track sleep and autonomic parameters and rated their level of perceived exertion (Borg Rating of Perceived Exertion) and subjective sleepiness after a 24-hour shift. Predictive variables included total run time and total run time after 11:59 PM. Total run time and sleep duration accounted for Borg Rating of Perceived Exertion and subjective sleepiness, while total run time and total run time after 11:59 PM accounted for sleep durations on-duty. The current results suggest that emergency call volume is associated with indicators of exertion and sleep. As such, call volume tracking is an important consideration for departments to ensure personnel readiness and wellness and provide a method of tracking the occupational demands experienced by firefighters on-duty.

Exploring the impact of 12-hour shifts on police officers' personal lives: a case study in the City of Tshwane, South Africa

Shift work has become a necessity in various professions, including law enforcement, to ensure the continuous operation of essential services. The implementation of 12-hour shifts has become common practice in police departments, aiming to meet the demands of public safety. However, the implications of such extended work periods on the personal lives of police officers are significant and warrant exploration. This study focuses on examining the effects of a 12-hour shift schedule on police officers within the South African Police Service (SAPS) stationed in the City of Tshwane, Gauteng province, South Africa. Through qualitative research methods, data was collected from eight police officers with a minimum of two years of experience through face-to-face interviews. Thematic content analysis was used to analyse the data systematically. Findings reveal that the 12-hour shift system presents challenges in maintaining a healthy work-life balance, impacting officers' social and familial responsibilities, participation in cultural and religious activities, and overall well-being. Officers expressed concerns about fatigue, limited time for family and leisure activities, and conflicts with personal commitments. Addressing these challenges is crucial for enhancing the health and effectiveness of police personnel and ensuring a positive work-life balance. This study contributes to the existing body of knowledge by shedding light on the nuanced effects of the 12-hour shift system on police officers' personal lives, particularly in the South African context. Recommendations were also made to address the effects of the shift system on officer’s personal life.

Evaluating Reception Center Models for Radiation Response Screening Capacity and Throughput Predictions.

Introduction: The current fleet of nuclear reactors in the United States is mandated to provide evidence that surrounding jurisdictions can screen their populations should an incident occur. Capacity can be measured as throughput in reception centers used for screening. Due to the significant staffing and resources required to exercise screening capacity, most jurisdictions typically perform smaller exercises and use models to estimate their overall throughput. Objective: To evaluate the applicability and realism of current throughput models and practices. Methods: Throughput capacity for radiation screening is estimated with a mathematical model derived by the Federal Emergency Management Agency (FEMA). The Centers for Disease Control and Prevention developed a discrete event simulation model as a tool, SimPLER, to evaluate capacity and make throughput predictions. Model estimates will be compared and evaluated using timing data collected at a large-scale exercise. Results: The FEMA model estimated a throughput 41.2% higher than the actual radiation screening throughput, while the SimPLER model provided identical values. The FEMA and SimPLER models' predicted throughputs were 50% and 3.8%, respectively, higher than total exercise throughput. Applying each model to the throughput projections for a 12-hour shift, the FEMA model estimates ranged from 665 to 6,646 people and the SimPLER model yielded an estimated throughput of 1,809 people with a standard deviation of 74.6. Conclusion: Discrete event simulation models, such as SimPLER, may provide more realistic and accurate predictions of radiation screening and throughput capacity of reception centers than mathematical models such as the FEMA model.

A Pilot Study in Fatigue Risk Management Among Obstetrics and Gynaecology Residents at the University of Alberta

ObjectivesCombatting fatigue is an ongoing challenge in surgical residency programs impacting both patient care and resident well-being. There is a gap in understanding the nuances of fatigue perpetuation, especially where it relates to specific on-call duties. This pilot study seeks to explore the extent of sleep deprivation among Obstetrics and Gynecology (OBGYN) residents and identify obstacles to obtaining adequate rest. MethodsA survey was sent out to all OBGYN residents at the University of Alberta, collecting demographic and baseline sleep information and assessing perceived barriers to sleep. Residents then self-selected for participation in the second portion which involved recording all pages in a 12-hour shift and assigning an acuity rating to them. Mixed methods were used including thematic analysis of the page acuity survey and descriptive statistics for the primary survey. ResultsIn total, 21 residents completed the initial survey (67.7%) and 17 12-hour shifts were recorded. While junior residents (postgraduate year 1–2) and those carrying the low-risk pager slept less on call and had less sleep on days without call, barriers to sleep were not different when compared to senior residents and those carrying the high-risk pager. While low-risk and high-risk shifts had different primary contributors to fatigue (volume and acuity, respectively) both groups attributed fatigue to non-urgent pages. On review of pages, 49.4% were perceived as non-urgent. A total of 81% of residents supported the development of problem boards to reduce the number of non-urgent pages. ConclusionsThis pilot study demonstrated residents, regardless of seniority or shift, found non-urgent pages to be a significant contributor to on-call fatigue and supported the use of problem boards to reduce pages. Our approach can provide a framework for other institutions to learn more about resident fatigue and non-urgent paging in their program.

Saving ambulance resources: a service evaluation of the identification of non-viable out-of-hospital cardiac arrest in London by advanced paramedic practitioners in critical care.

Advanced paramedic practitioners in critical care (APPCCs) are advanced clinical practitioners focused on the delivery of pre-hospital critical care. While working in an ambulance control room setting, APPCCs seek to identify emergency calls appropriate for operational APPCCs to attend. These would include out-of-hospital cardiac arrest (OHCA). Through interrogation of incoming emergency calls they are also able to identify OHCA calls where resuscitation may be futile. In these cases, and within a governance framework, they stand down multiple ambulance responders, leaving only the closest responding resource to attend, thereby 'saving resources' that can be re-directed to other waiting emergency calls. It is believed that this is the first initiative of this nature in the United Kingdom. A three-year retrospective service evaluation of data was undertaken. The aim was to quantify the number of 'saved resources', including both double crewed ambulances (DCAs) and solo (single-person) responders, and furthermore to equate those savings into potential hours saved, using average known job cycle times (JCTs). Additionally, safety was assessed by searching all mandated incident reports for occasions where, despite cancellation of resources by an APPCC, resuscitation was commenced by the first response to scene. A total of 13,356 ambulance resources were saved. Of these, 6593 (49.4%) were DCAs and 6763 (50.6%) were solo responders. Using the average JCT for deceased patients of 104.8 minutes, the total time saving equated to 23,328.48 hours of work or 1944.04 12-hour shifts. When considering DCAs alone, the average JCT for obviously deceased patients was 110.9 minutes. This equates to 12,186.1 hours of work or 1015.5 12-hour shifts. A total of 15 incident reports were identified. All had been investigated, revealing appropriate decision making in cancelling ambulance resources. No patient harm was identified. APPCCs working within a governance framework safely saved a significant number of ambulance resources over a three-year period. Perceived benefits include 'freeing up' DCA and solo responders, allowing them to be redirected to other emergency calls, leading to potential improvement in response times for patients waiting for an ambulance resource.

Validation of a scale to measure the workload of midwives

Objective: To validate the design of a scale to measure the workload of the midwives based on Classification of Nursing Interventions (NIC), through their multicentric application in different delivery units. Methods: Quantitative, longitudinal, study multicentric character, conducted in three general university hospitals of the public system of health. The sample consisted of fifty midwives, who examined the validity of the construct of the designed scale, for a total of 370 births. Data collection began through the scale designed ad hoc by the research team, accounting for the time and average number of NIC interventions, performed at each birth. Results: The midwives of the study, are subject to an increase in their workload regarding the number and average time spent conducting interventions NIC in each attended delivery. In their working day (12-hour shift) they allocate 960.61 minutes (16 hours in day shift) and 840.29 minutes (14 hours in night shift), to execute their roles in childbirth attendance. Conclusion: The data indicate the validity of the scale designed ad hoc, as this instrument reflects the actual workload experienced by the midwives of the study.

A nationwide cross-sectional study investigating adherence to the Mediterranean diet, smoking, alcohol and work habits, hormonal dynamics between breast cancer cases and healthy subjects

Background & AimsDespite substantial efforts in promoting prevention and the advancements in surgical and minimally invasive techniques, breast cancer remains a leading cause of mortality among women worldwide. Genetics and risk factors, including diet and lifestyle, play a critical role in determining the susceptibility to this neoplasm. The primary objective of this study is to investigate the pivotal role of adherence to the Mediterranean diet in breast cancer prevention. Additionally, we assessed differences in diet, Body Mass Index (BMI), smoking and alcohol habits, work shifts, exposure to environmental pollutants, and hormonal factors between patients with previously diagnosed breast cancer and healthy subjects. MethodsThe validated CREA questionnaire, alongside additional inquiries, was administered to the Italian population. Adherence to the Mediterranean diet was examined, and respondents were categorized into two groups: the general population and patients with a previous cancer diagnosis. Descriptive and inferential statistics were applied to assess all risk factors among these groups. ResultsResults revealed low adherence to the Mediterranean diet, particularly among less educated individuals, those engaged in 24-hour shift work, smokers, and those with a high BMI. Furthermore, significant differences in working time distribution, consumption of meat, milk, and alcohol, as well as significant differences in hormonal factors such as age of menarche and menopause, age of first pregnancy, number of children and abortions, breastfeeding time, and contraceptive use were observed among these groups. ConclusionsThese findings underscore the importance of targeted interventions and personalized strategies to address specific risk factors and enhance preventive measures for individuals at risk.

Emergency physician personnel crisis: a survey on attitudes of new generations in Slovenia

BackgroundEmergency departments globally are overburdened, and emergency medicine residency is losing popularity among students and physicians. This raises concerns about the collapse of a life-saving system. Our goal was to identify the key workforce reasoning and question medical staff employment behavior.MethodsThis was a prospective cross-sectional study. In December 2022, medical students and pre-residency doctors in Slovenia were invited to complete a web-based questionnaire. The data were analyzed using T-test, chi-square test, Mann‒Whitney-Wilcoxon tests, and principal component analysis. Open-ended questions were hand-categorized.ResultsThere were 686 participatns who clicked on the first page and 436 of those finished the survey. 4% of participants gave a clear positive response, while 11% responded positively regarding their decision to pursue emergency medicine residency. The popularity of emergency medicine decreases significantly among recent medical school graduates upon their initial employment. People who choose emergency medicine are less concerned about its complexity and pressure compared to others. Most respondents preferred 12-hour shift lengths. The preferred base salary range for residents was I$ 3623–4529, and for specialists, it was I$ 5435–6341. The sample’s primary personal priorities are achieving a satisfactory work-life balance, earning respect from colleagues, and engaging in academic activities. Factors that attract individuals to choose emergency medicine include high hourly wages, establishment of standards and norms, and reduced working hours.ConclusionsOur findings indicate that enhancing compensation, establishing achievable standards and norms, facilitating a beneficial work-life equilibrium, providing assistance with initial property acquisition, stimulating participation in deficit residency programs, fostering collegiality among peers, restricting the duration of shifts, and enabling pension accrual may be imperative in attracting more individuals to pursue emergency medicine residency.

(346) Simultaneous Bladder Drainage via Suprapubic and Urethral Catheters: Which Drains More Completely and Why?

Abstract Introduction Reconstructive urologists often place both a urethral and suprapubic catheter intraoperatively to prevent extravasation of undrained urine across anastomosis sutures. As no consensus exists on which catheter drains the bladder more completely, many surgeons leave one catheter to gravity drainage and cap the other postoperatively. Objective We sought to identify differences in catheter urine outflow during dual bladder drainage with suprapubic and urethral catheters in postoperative urology patients. Methods Urine output (UOP) from transgender men who underwent Stage II Phalloplasty with urethral lengthening was retrospectively reviewed. Both 16 French urethral and suprapubic catheters were placed to gravity drainage postoperatively. UOP from each catheter was recorded separately, twice daily. Mixed model regression modeling tested for differences in urine output by time of day (day/night) and activity status (Bedrest: Postop Day 0-2, Ambulatory: Postop Day 3+). Results The aggregate number of 12-hour shift UOP observations was 250 (125 for urethral and 125 for suprapubic catheters) across 14 inpatients. Suprapubic catheters had a mean 410 ml higher output than urethral catheters per 12-hour shift (p=0.002; 95% CI: 185, 636 ml). During daytime, suprapubic catheters demonstrated higher UOP than urethral catheters per 12-hour shift (Estimated Difference: 464 ml; p=0.002; 95% CI: 211, 718 ml). During nighttime, a similar phenomenon was observed (Estimated Difference: 356 ml; p=0.009; 95% CI: 104, 606 ml). When comparing mean UOP from each catheter during the Bedrest Phase, suprapubic catheters averaged an estimated 295 ml higher UOP compared to urethral catheters per 12-hour shift with a trend toward statistical significance (p=0.052; 95% CI -3, 594 ml). During the Ambulatory Phase, mean suprapubic catheter UOP was an estimated 472 ml higher than urethral catheters per 12-hour shift (p=0.009; 95% CI 142, 802 ml) (Table 1). Conclusions Simultaneous bladder drainage with urethral and suprapubic catheters shows greater drainage from the suprapubic catheter (35% vs 65%). The difference in urinary drainage is likely explained by the suprapubic catheter tip and drainage inlet residing in a more gravity-dependent location, within the funnel-shaped bladder neck (Figure 1). When using two catheters, both can be placed to gravity to maximize bladder drainage as the suprapubic catheter can drain residual urine not adequately drained by the urethral catheter.

Would you like to be a general practitioner? Baseline findings of a longitudinal survey among Danish medical trainees

BackgroundRecruiting and securing primary care physician workforce has been the center of international attention for decades. In Denmark, the number of general practitioners has decreased by 8.5% since 2013. However, a rising population age and increasing prevalence of chronic diseases and multimorbidity place an even greater future need for general practitioners in Denmark. The choice of general practice as specialty has been associated with a range of both intrinsic and extrinsic factors, however, few studies have examined the recruitment potential that lies within medical trainees’ who are undecided about general practice specialization. The aim of this study was, therefore, to explore how medical trainees who are undecided about general practice specialization (GP-positive/undecided) differ from medical trainees who are either committed (GP-committed) or not committed to a general practice career (GP-non-committed) regarding factors related to future work life.MethodsThe present study concerns baseline findings from a longitudinal survey study. An online questionnaire was e-mailed to a national cohort of medical trainees during their transition from under- to postgraduate education. The associations between orientations towards general practice specialization and work-related factors and potential influencing factors, respectively, were analyzed using uni- and multivariable modified Poisson regression models.ResultsOf 1,188 invited participants, 461 filled out key study variables concerning specialty preferences and rejections, corresponding to a response rate of 38.8%. We found significant positive associations between GP-positive/undecided orientation and valuing a good work/life balance and the opportunity to organize own working hours when compared to GP-non-committed respondents. Compared to the GP-committed orientations, the GP-positive/undecided orientation was associated with a positive attitude towards technology, working shift hours, and an openness towards several career paths. Across all orientations, undergraduate exposure to the specialties was found to be highly influential on the specialty preferences.ConclusionGP-positive/undecided medical trainees value autonomy over their working hours more than the GP-non-committed, but less than the GP-committed. However, the GP-positive/undecided respondents present more openness to different career opportunities and the use of technology in daily work. We suggest using this knowledge in the planning of recruitment strategies aiming to increase interest in general practice specialization.

Association Between Nurse Copatient Illness Severity and Mortality in the ICU.

In the context of traditional nurse-to-patient ratios, ICU patients are typically paired with one or more copatients, creating interdependencies that may affect clinical outcomes. We aimed to examine the effect of copatient illness severity on ICU mortality. We conducted a retrospective cohort study using electronic health records from a multihospital health system from 2018 to 2020. We identified nurse-to-patient assignments for each 12-hour shift using a validated algorithm. We defined copatient illness severity as whether the index patient's copatient received mechanical ventilation or vasoactive support during the shift. We used proportional hazards regression with time-varying covariates to assess the relationship between copatient illness severity and 28-day ICU mortality. Twenty-four ICUs in eight hospitals. Patients hospitalized in the ICU between January 1, 2018, and August 31, 2020. None. The main analysis included 20,650 patients and 84,544 patient-shifts. Regression analyses showed a patient's risk of death increased when their copatient received both mechanical ventilation and vasoactive support (hazard ratio [HR]: 1.30; 95% CI, 1.05-1.61; p = 0.02) or vasoactive support alone (HR: 1.82; 95% CI, 1.39-2.38; p < 0.001), compared with situations in which the copatient received neither treatment. However, if the copatient was solely on mechanical ventilation, there was no significant increase in the risk of death (HR: 1.03; 95% CI, 0.86-1.23; p = 0.78). Sensitivity analyses conducted on cohorts with varying numbers of copatients consistently showed an increased risk of death when a copatient received vasoactive support. Our findings suggest that considering copatient illness severity, alongside the existing practice of considering individual patient conditions, during the nurse-to-patient assignment process may be an opportunity to improve ICU outcomes.
