Sleep and fatigue management strategies: How nurses, midwives and paramedics cope with their shift work schedules-a qualitative study.

AIMS: To understand the benefits and challenges of shift work, and the coping strategies used by nurses, midwives and paramedics to manage the impact of shift work on sleep and fatigue from shift work. DESIGN: A single case study with embedded units. METHODS: Twenty-seven participants were interviewed exploring their shift work experiences, coping strategies used to improve sleep, and what their recommendations are for improving shift work management. Interviews were completed between November and December 2022. RESULTS: Participants enjoyed the lifestyle, flexibility and financial rewards offered by working shift work. However, fatigue and sleep deprivation undermined these benefits, as it impacted their ability to enjoy social and family events. There were also concerns of long-term health consequences of shift work and delivery of care. Changes to rostering practices and sleep and shift work education were common recommendations. CONCLUSION: This study provides insights on how healthcare professionals manage sleep and fatigue due to shift work and the inadequate support. There is absence of adequate policies, processes and training at an organizational, academic and personal level on how to best manage sleep and fatigue when working shift work. Future research is needed to explore how to equip healthcare shift workers with the skills to successfully manage their schedules to mitigate the negative impact that poor sleep and fatigue has on the health and safety of themselves and their patients. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Understanding the specific challenges of shift work and how workers manage their shift work schedules is critical for improving the health and safety of themselves and their patients. This study identified that there is insufficient training regarding sleep and shift work management strategies, potentially leading to occupational health and safety concerns. Further education and training to equip staff with the necessary information, training and guidance to staff on how to reduce fatigue risk is required. PATIENT OR PUBLIC CONTRIBUTION: This study involved healthcare shift workers in semi-structured interviews. Data gathered from a previous survey that participants were involved in helped shape the interview topics and the study design.

[Sleep Strategies for Shift Work Nurses].

To meet the demands of a 24/7 society, shift work is necessary. Shift work is outside the traditional regular 9-to-5 work schedule, is characterized by irregular working hours, and exists in various industries. However, this abnormal working time can disrupt the natural day and night rhythm, and if poorly adjusted, it can lead to shift work sleep disorder (SWSD). SWSD is associated with multiple health risks, including impaired cognitive function, increased risk of accidents, and various metabolic and cardiovascular diseases. The frontline nurses typically work shifts to provide comprehensive patient care. This article aims to discuss sleep physiology, apply existing literature to discuss the impact on nurses resulting from shift work, and further offer strategies to regulate sleep to promote physical and mental health. These strategies range from organizational interventions (e.g., optimizing shift schedules) to individual interventions (e.g., lifestyle changes) and the use of chronobiological techniques (e.g., light therapy) to promote the adjustment of circadian rhythms, etc.

Night shift work and risk of aggressive prostate cancer in the Norwegian Offshore Petroleum Workers (NOPW) cohort.

BACKGROUND: Night shift work may acutely disrupt the circadian rhythm, with possible carcinogenic effects. Prostate cancer has few established risk factors though night shift work, a probable human carcinogen, may increase the risk. We aimed to study the association between night shift work and chlorinated degreasing agents (CDAs) as possible endocrine disrupters in relation to aggressive prostate cancer as verified malignancies. METHODS: We conducted a case-cohort study on 299 aggressive prostate cancer cases and 2056 randomly drawn non-cases in the Norwegian Offshore Petroleum Workers cohort (1965-98) with linkage to the Cancer Registry of Norway (1953-2019). Work history was recorded as years with day, night, and rollover (rotating) shift work, and CDA exposure was assessed with expert-made job-exposure matrices. Weighted Cox regression was used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for aggressive prostate cancer, adjusted for education and year of first employment, stratified by 10-year birth cohorts, and with 10, 15, and 20 years of exposure lag periods. RESULTS: Compared with day work only, an increased hazard of aggressive prostate cancer (HR = 1.86, 95% CI 1.18-2.91; P-trend = 0.046) was found in workers exposed to ≥19.5 years of rollover shift work. This persisted with longer lag periods (HR = 1.90, 95% CI 0.92-3.95; P-trend = 0.007). The exposure-hazard curve for a non-linear model increased linearly (HRs ≥1.00) for 18-26 years of rollover shift work. No association was found with CDA exposure. CONCLUSIONS: Long-term exposure to rollover shift work may increase the hazard of aggressive prostate cancer in offshore petroleum workers.

The association between circadian rhythm of cortisol and shift work regularity among midwives-A multicenter study in Southeast China.

Objective: This article aims to explore the association between the trends of cortisol rhythm and the regularity of shift work among midwives. Methods: Midwives from six Southeast Chinese hospitals were recruited through cluster sampling in a multi-center cross-sectional study. Urine samples were collected half an hour after waking up, at 11:00, 19:00, and 23:00 on two consecutive days in a longitudinal cohort. The urinary cortisol was assayed by the chemiluminescence method. Results: A total of 86 midwives were included in this study, contributing 688 cortisol samples. The midwives displayed a circadian rhythm in cortisol secretion, with zeniths in the morning and nadirs in the evening. The trend of the first day was repeated on the second day. Although the total working hours per week of the two groups, namely the regular shift group (N = 43) and the irregular shift group (N = 43), were the same, significant main effects of groups (F = 62.569, p < 0.001), time (F = 45.304, p < 0.001), and group-by-time interaction (F = 226.695, p < 0.001) were indicated through linear mixed models. The main effect of day was not statistically significant, with F = 0.105 and p = 0.746. The fluctuation range of cortisol curve in the group with irregular schedules was slightly lower than that in the group with regular schedules. Conclusion: Our results may indicate that cortisol was more inhibited in midwives with irregular shift patterns than those with regular shift patterns. It is necessary to further study the relationship between cortisol rhythm and patterns of midwives' shifts in future so as to lay a foundation for hospital managers to develop a more reasonable scheduling system for midwives with the further purpose to minimize their occupational fatigue and ensure the safety of mothers and infants.

A Cross-Sectional, Exploratory Study on the Impact of Night Shift Work on Midwives' Reproductive and Sexual Health.

BACKGROUND: Shift work is the basis for health care system functioning. The non-standard schedules enforce abrupt changes in the timing of sleep and light-dark exposure. It can contribute to the increased risk of various medical conditions, including reproductive and sexual health issues. The purpose of the study was to assess the impact of shift work with night shifts on midwives' reproductive and sexual health. METHODS: This cross-sectional, exploratory study included 520 midwives. A descriptive questionnaire was distributed in person (414) and online (106) from July 2019 to May 2020. We used the Female Sexual Function Index (PL-FSFI) standardized questionnaire and proprietary research tools (applicable to demographic and social data and reproductive health). All statistical calculations were performed with the IBM SPSS 23 statistical package. RESULTS: Shift work affects midwives' reproductive and sexual health. Midwives working night shifts are more likely to experience reproductive problems and sexual dysfunctions. The most pronounced differences are observed in the experience of infertility and the number of miscarriages. PL-FSFI results clearly showed the adverse impact of working shifts including night shifts on functioning in various dimensions of sexual health. CONCLUSION: Shift work negatively affects reproductive and sexual health and causes work-life conflict experience. It is necessary to develop procedures that minimize shift rotation and implement work schedules that allow for recuperation or rest and ensure proper family and social life.

Beyond the limits of circadian entrainment: Non-24-h sleep-wake disorder, shift work, and social jet lag.

While the vast majority of humans are able to entrain their circadian rhythm to the 24-h light-dark cycle, there are numerous individuals who are not able to do so due to disease or societal reasons. We use computational and mathematical methods to analyze a well-established model of human circadian rhythms to address cases where individuals do not entrain to the 24-h light-dark cycle, leading to misalignment of their circadian phase. For each case, we provide a mathematically justified strategy for how to minimize circadian misalignment. In the case of non-24-h sleep-wake disorder, we show why appropriately timed bright light therapy induces entrainment. With regard to shift work, we explain why reentrainment times following transitions between day and night shifts are asymmetric, and how higher light intensity enables unusually rapid reentrainment after certain transitions. Finally, with regard to teenagers who engage in compensatory catch-up sleep on weekends, we propose a rule of thumb for sleep and wake onset times that minimizes circadian misalignment due to this type of social jet lag. In all cases, the primary mathematical approach involves understanding the dynamics of entrainment maps that measure the phase of the entrained rhythm with respect to the daily onset of lights.

Assessment of Stress Salivary Markers, Perceived Stress, and Shift Work in a Cohort of Fishermen: A Preliminary Work.

Due to work-related stress, today, work itself represents a daily challenge that must be faced in many occupations. While, in the past, the scientific community has focused on the helping professions, since, an increasing number of professions have since been investigated. Therefore, different approaches exist in order to assess this disorder, representing a scientific field wherein biological and psychological dimensions both need to be evaluated. In this paper, we consider three biological salivary markers: interleukin 1 beta (IL-1ß), cortisol, and melatonin. The choice derives from recent contributions to the literature in which the interplay between these markers has been verified. Briefly, such interplay could explain how the central nervous, endocrine, and immune systems communicate with each other, supporting a holistic concept of person. In 30 marine fishermen from the Apulia region of Italy, perceived stress was measured using the Professional Stress Scale (PSS) and sleep disturbances were assessed through the Pittsburgh Sleep Quality Index (PSQI). Salivary markers were collected at 8:00 a.m. and 2:00 p.m. Those subjects reporting sleep disturbance and having altered scores in two PSS subclasses, home-work conflict and self-esteem, presented inverted salivary melatonin and cortisol nictemeral rhythms (with regard to melatonin levels at 8:00 a.m., those workers reporting values higher than the median showed 64.1% versus 48.6% home-work conflict with respect to cortisol levels, subjects having an inverted circadian rhythm showed 69.9% versus 52.5% home-work conflict, and these values resulted 47.7% versus 25.3% when the self-esteem was considered). As regards melatonin, PSQI score is statistically different in the two groups of subjects as identified by median melatonin at 8:00 a.m.; specifically, the subjects who had mean values higher than the median shared higher PSQI scores (10.8 versus 9.8). The same subjects reported more frequent home-work conflict and more sleep disorders. We found a negative correlation between IL-1ß at 8:00 a.m. and Cortdiff (the difference between cortisol at 8:00 a.m.-cortisol at 2:00 p.m.), and that high IL-1ß at 8:00 a.m. was associated with low Cortdiff. Based on our results we would like to propose this approach in health surveillance, in order to prevent mental and/or physical disorders, however our study is surely preliminary. The interesting perspectives and hypotheses cited in this paper, in which the roles of IL-1ß and norepinephrine appear central and important, could remain hypothetical if not supported by more robust observation in order to produce, truly, new knowledge. In the future we will deepen this study with a larger sample, and if these results will be confirmed, this approach could allow preventing, not only mental and physical disorders, but also immuno-mediated diseases, and, perhaps, cancer.

Night shift work, chemical coexposures and risk of female breast cancer in the Norwegian Offshore Petroleum Workers (NOPW) cohort: a prospectively recruited case-cohort study.

OBJECTIVES: This study examined the association between night shift work and risk of breast cancer, overall and by hormone receptor subtype, among females in the Norwegian Offshore Petroleum Workers (NOPW) cohort. We also examined the association of coexposure (chlorinated degreasers and benzene) and breast cancer risk, and possible interaction with work schedule. DESIGN: Prospectively recruited case-cohort study within the NOPW cohort. SETTING: Female offshore petroleum workers active on the Norwegian continental shelf. PARTICIPANTS: 600 female workers (86 cases and 514 non-cases) were included in the study. We excluded workers that died or emigrated before start of follow-up, had missing work history, were diagnosed with breast cancer or other prior malignancy (except non-melanoma skin cancer) before start of follow-up. RESULTS: No overall association was found between breast cancer risk and work schedule (HR 0.87, 95% CI 0.52 to 1.46 for work schedule involving night shift vs day shift only). There was no significant association between work schedule and risk of any breast cancer subtype. No significant interactions were found between work schedule and chemical coexposures (breast cancer overall Pinteraction chlorinated degreasers=0.725 and Pinteraction benzene=0.175). CONCLUSIONS: Our results did not provide supporting evidence that work schedule involving night shift affects breast cancer risk in female offshore petroleum workers, but should be considered cautiously due to few cases. Further studies with larger sample sizes are warranted.

The Effect of Shift Work on the Overall Health Status of Hospital-Employed Nursing Staff in Bosnia and Herzegovina: A Cross-Sectional Study.

BACKGROUND: Nursing is a profession frequently organized around shift work in order to guarantee the continuity of care throughout the 24 hours. However, working in shifts is coupled with the desynchronization of circadian rhythms and may result in adverse effects on nurses' health. Our previous work has demonstrated the presence of increased stress levels, reduced coping abilities and diminished life enjoyment in shift work nurses in comparison to those working only in accordance with the daily schedule. Here we aimed to appraise the effects of shift work on their overall health status. SUBJECTS AND METHODS: We used a comparative cross-sectional approach on a sample of 157 hospital nursing professionals at the University Clinical Hospital Mostar. Study subjects were divided into two groups: a total of 51% study subjects were included in a specific type of shift work (i.e., 12-hour day shift / 24 hours off / 12-hour night shift / 48 hours off), while the remaining 49% adhered to the conventional 7-hour daily schedule. The instrument used was a Standard Shiftwork Index (SSI), together with a comprehensive appraisal of participants' socio-demographic characteristics. Descriptive and inferential statistical methods were applied, and statistical significance was set at p≤0.05 (two-sided). RESULTS: The results have shown that nurses in shift work were significantly more burdened with gastrointestinal disturbances (p<0.001); more specifically, there was a higher frequency of appetite loss (p=0.003), heartburn (p=0.03), nausea (p<0.01) and weight gain (p=0.05) when compared to nursing professionals in the day shift. Conversely, there were no statistically significant differences in cardiovascular health between these two groups. In addition, nurses in shift work more frequently presented with headaches (p=0.001) and varicose veins of lower extremities (p=0.037) in comparison to nurses working only in accordance with the daily schedule. CONCLUSIONS: Shift work can adversely influence psychophysical homeostasis, resulting not only in substandard performance of nursing staff, but also potentially hazardous effects on their overall health status. More specifically, we recognized shift work as a substantial risk factor for gastrointestinal and metabolic disorders in nurses; likewise, the increased prevalence of headaches may consequently have a detrimental effect on social and family relationships. All of this should be tackled in a holistic and organized way, together with any additional psychological/sleep issues.

Light entrainment of the SCN circadian clock and implications for personalized alterations of corticosterone rhythms in shift work and jet lag.

The suprachiasmatic nucleus (SCN) functions as the central pacemaker aligning physiological and behavioral oscillations to day/night (activity/inactivity) transitions. The light signal entrains the molecular clock of the photo-sensitive ventrolateral (VL) core of the SCN which in turn entrains the dorsomedial (DM) shell via the neurotransmitter vasoactive intestinal polypeptide (VIP). The shell converts the VIP rhythmic signals to circadian oscillations of arginine vasopressin (AVP), which eventually act as a neurotransmitter signal entraining the hypothalamic-pituitary-adrenal (HPA) axis, leading to robust circadian secretion of glucocorticoids. In this work, we discuss a semi-mechanistic mathematical model that reflects the essential hierarchical structure of the photic signal transduction from the SCN to the HPA axis. By incorporating the interactions across the core, the shell, and the HPA axis, we investigate how these coupled systems synchronize leading to robust circadian oscillations. Our model predicts the existence of personalized synchronization strategies that enable the maintenance of homeostatic rhythms while allowing for differential responses to transient and permanent light schedule changes. We simulated different behavioral situations leading to perturbed rhythmicity, performed a detailed computational analysis of the dynamic response of the system under varying light schedules, and determined that (1) significant interindividual diversity and flexibility characterize adaptation to varying light schedules; (2) an individual's tolerances to jet lag and alternating shift work are positively correlated, while the tolerances to jet lag and transient shift work are negatively correlated, which indicates trade-offs in an individual's ability to maintain physiological rhythmicity; (3) weak light sensitivity leads to the reduction of circadian flexibility, implying that light therapy can be a potential approach to address shift work and jet lag related disorders. Finally, we developed a map of the impact of the synchronization within the SCN and between the SCN and the HPA axis as it relates to the emergence of circadian flexibility.

Exogenous melatonin decreases circadian misalignment and body weight among early types.

Shift workers experience chronic circadian misalignment, which can manifest itself in reduced melatonin production, and has been associated with metabolic disorders. In addition, chronotype modulates the effect of night shift work, with early types presenting greater circadian misalignment when working night shift as compared to late types. Melatonin supplementation has shown positive results reducing weight gain in animal models, but the effect of exogenous melatonin in humans on body weight in the context of shift work remains inconsistent. The aim of this study was thus to evaluate the effects of exogenous melatonin on circadian misalignment and body weight among overweight night shift workers, according to chronotype, under real-life conditions. We conducted a double-blind, randomized, placebo-controlled, crossover trial where melatonin (3 mg) or placebo was administered on non-night shift nights for 12 weeks in 27 female nurses (37.1 yo, ±5.9 yo; BMI 29.9 kg/m2 , ±3.3 kg/m2 ). Melatonin (or placebo) was only taken on nights when the participants did not work night shifts, that is, on nights when they slept (between night shifts and on days off). Composite Phase Deviations (CPD) of actigraphy-based mid-sleep timing were calculated to measure circadian misalignment. The analyses were performed for the whole group and by chronotype. We found approximately 20% reduction in circadian misalignment after exogenous melatonin administration considering all chronotypes. Moreover, melatonin supplementation in those who presented high circadian misalignment, as observed in early chronotypes, reduced body weight, BMI, waist circumference, and hip circumference, without any change in the participants' calorie intake or physical activity levels.

Evaluación de una intervención para mejora en la administración segura de medicación en el turno de noche / An Intervention to Improve Safe Administration of Medication in the Night Shift

Introducción: Uno de cada siete pacientes hospitalizados experimenta un evento adverso relacionado con la administración de medicación. Los errores de medicación son una de las causas más importantes de mortalidad y morbilidad prevenible. Objetivo: Evaluar la eficacia de una intervención formativa sobre la población de enfermeras de turno de noche de un hospital de agudos para mejorar el cumplimiento del protocolo de administración segura de medicación. Métodos: Ensayo experimental, pre-post intervención formativa, realizado en Hospital Clínic de Barcelona, durante 2015-2016. Población: 268 enfermeras en dos turnos de noche, muestra: 177 participantes (88 Grupo Control y 89 Grupo Experimental). La intervención consistió en sesiones informativas y acceso a Procedimiento escrito. El instrumento de medida fue el Procedimiento Normalizado de Trabajo de la institución mediante check-list de cumplimiento. Se realzó estudio uni-bivariable, mediante Chi2 y test de Fisher con significancia para p < 0,05. Resultados: Se realizaron 219 observaciones en Grupo Control y 207 en Grupo Experimental. De 17 variables analizadas, solo tres mostraron diferencias significativas: en Grupo Experimental mejoró el conocimiento del Procedimiento; se incrementó el uso del agua y jabón sobre la solución hidroalcohólica; y empeoró la identificación normalizada de fármacos pendientes de administrar. Ninguna de las 14 variables restantes mostró diferencias significativas. De 426 observaciones, solo se produjeron 3 errores de medicación en Grupo control, subsanados antes de su administración, y 0 en Grupo Experimental. Conclusiones: Las intervenciones formativas clásicas con receptores pasivos pueden no ser eficaces para mejorar la práctica enfermera en administración segura de medicación(AU)

Introduction: One in seven hospitalized patients experiences an adverse event related to administration of medication. Medication errors are one of the most important causes of preventable mortality and morbidity. Objective: To assess the efficacy of a training intervention with the population of night shift nurses in an acute care hospital, in order to improve compliance with the protocol for the safe administration of medication. Methods: Experimental trial, pre-post training intervention, carried out at Hospital Clínic of Barcelona, during 2015-2016. The population consisted of 268 nurses in two night shifts. The sample consisted of 177 participants (88 from the control group and 89 from the experimental group). The intervention consisted in information sessions and access to a written procedure. The measurement instrument was the Institution's Standard Work Procedure by means of a compliance check-list. Uni-bivariate study was performed, using chi-square and Fisher's test with a significance of P < 0.05. Results: 219 observations were carried out in the control group and 207, in the experimental group. Of seventeen variables analyzed, only three showed significant differences: in the experimental group, knowledge of the procedure improved, increase in the use of soap and water over hydroalcoholic solution, and worsening of standardized identification of drugs pending from being administered. None of the fourteen remaining variables showed significant differences. Of 426 observations, only three medication errors occurred in the control group, corrected before its administration, and zero occurred in the experimental group. Conclusions: Classic training interventions with passive receptors may not be effective to improve nursing practice in safe administration of medication(AU)

Improved Sleep Quality and Work Performance Among Shift Workers Consuming a "Foods with Function Claims" Containing Asparagus Extract.

The purpose of this study was to examine whether Foods with Function Claims (FFC) containing asparagus extract effectively improved sleep quality and work performance in shift workers. An intervention study with a before-and-after intervention design was conducted on nurses engaged in two-shift work at a hospital, ingesting a FFC containing asparagus extract. The evaluation period lasted at least two weeks, including three nights shifts during the period. Before and after ingestion, Pittsburgh Sleep Questionnaire Index (PSQI), Utrecht Work Engagement Scale (UWES), Sleep quality (VAS-rated), impaired work functioning, and psychiatric symptoms were evaluated. A diary record, wearing of an activity meter, and a Psychomotor vigilance test were also performed at baseline and after intervention. Data were analyzed by the paired t-test or the Wilcoxon rank sum test. Among 34 participants, 33 completed the study. The results of the primary outcome measures showed significant improvements in PSQI and Sleep Quality in the night of the day after a night shift (PSQI total score: base line 7.41/ post intervention 6.03: P < 0.001; sleep quality: base line 4.48/post intervention 6.00: P < 0.001). The results of the secondary outcome measures showed significant improvements in UWES and feeling of fatigue. There was also trend of improvement in sleep efficiency and the reaction time. There was no significant improvement in impaired work functioning. This study showed that regular consumption of an FFC containing asparagus extract could improve sleep quality, feeling of fatigue, and work engagement among shift workers. Some caution, however, is needed when interpreting the results because of the before-and-after intervention design without a control group.

Environmental factors associated with biological use and surgery in inflammatory bowel disease.

BACKGROUND AND AIM: While major efforts were made studying the complex etiology of inflammatory bowel disease (IBD) including environmental factors, less is known about underlying causes leading to the heterogeneous and highly variable course of disease. As cigarette smoking cessation is the best-known environmental factor with beneficial effect in Crohn's disease (CD), more exposome factors are likely involved. Further insights into the role of the exposome in heterogeneity of disease might not only further knowledge of underlying pathways, but also allow for better risk stratification. METHODS: Seven hundred twenty-eight IBD patients completed the validated Groningen IBD Environmental Questionnaire, collecting exposome data for 93 exposome factors. Associations with disease course, that is, for need for surgery or biological therapy, were evaluated using univariate and multivariate-adjusted logistic regression modeling. RESULTS: No significant associations were seen after Bonferroni correction. However, 11 novel exposome factors were identified with P < 0.05. Two factors were associated with course of CD and ulcerative colitis (UC): beer (CD OR0.3/UC OR0.3) and cannabis (0.5/2.2). While in CD, carpet flooring (0.5) was associated with biological use, and four factors were associated with surgery: working shifts (1.8), appendectomy (2.4), frequent tooth brushing (2.8), and large household size (0.1). For UC, migrants more often required biologicals (10.2). Childhood underweight (3.4), amphetamine use (6.2), and cocaine use (4.8) were associated with surgery. Five factors were replicated. CONCLUSIONS: We identified 16 environmental factors nominally associated with biological use and surgery in established IBD. These new insights form an important stepping stone to guide research on biological pathways involved, risk stratification, tailor-made interventions, and preventive strategies in IBD.

A quasi-experimental study into the effects of naps and therapy glasses on fatigue and well-being.

AIM: To investigate the effects of a napping facility and therapy glasses on fatigue and well-being at the end of the night shift. BACKGROUND: Night shift work has adverse effects on fatigue and well-being. METHODS: A quasi-experimental study was conducted, and data were collected on 243 night shifts of 95 nurses who had either access to a napping facility, therapy glasses, both facilities or no facilities. Multilevel analyses were conducted to predict fatigue and well-being. RESULTS: Night shifts of nurses having access to both facilities were associated with less fatigue and more well-being. The use of therapy glasses related negatively to fatigue and positively to well-being. The use of the napping facility was not associated with fatigue and well-being. However, having slept while napping and sleeping time during napping were negatively associated with fatigue and positively associated with well-being. CONCLUSION: Therapy glasses and sleeping in a napping facility can be effective interventions in reducing the adverse effects of night shift work. IMPLICATIONS FOR NURSING MANAGEMENT: Therapy glasses seem an effective investment to facilitate the well-being of nurses. To enhance sleeping during napping, it is worthwhile to let nurses get accustomed to the napping facility and customize settings to personal preferences.

Individual Circadian Preference, Shift Work, and Risk of Medication Errors: A Cross-Sectional Web Survey among Italian Midwives.

BACKGROUND: In order to explore the possible association between chronotype and risk of medication errors and chronotype in Italian midwives, we conducted a web-based survey. The questionnaire comprised three main components: (1) demographic information, previous working experience, actual working schedule; (2) individual chronotype, either calculated by Morningness-Eveningness Questionnaire (MEQ); (3) self-perception of risk of medication error. RESULTS: Midwives (n = 401) responded "yes, at least once" to the question dealing with self-perception of risk of medication error in 48.1% of cases. Cluster analysis showed that perception of risk of medication errors was associated with class of age 31-35 years, shift work schedule, working experience 6-10 years, and Intermediate-type MEQ score. CONCLUSIONS: Perception of the risk of medication errors is present in near one out of two midwives in Italy. In particular, younger midwives with lower working experience, engaged in shift work, and belonging to an Intermediate chronotype, seem to be at higher risk of potential medication error. Since early morning hours seem to represent highest risk frame for female healthcare workers, shift work is not always aligned with individual circadian preference. Assessment of chronotype could represent a method to identify healthcare personnel at higher risk of circadian disruption.

The impact of sleep deprivation and alcohol on driving: a comparative study.

BACKGROUND: There is concern about the detrimental effects of shift-workers' increasing working hours particularly when driving sleep deprived. The approach to measuring the magnitude of driving impairment caused by sleep deprivation was by comparing it to alcohol. The study compared driving performance after 24-h of wakefulness to performance with a BrAC of just over 22 µg/100mls of breath which is equal to 50 mg of alcohol per 100mls of blood (Scottish drink-drive limit). The effectiveness of coffee as a countermeasure for driver fatigue and the association between subjective impairment and actual performance was also investigated. METHODS: A study of 30 participants (11 male and 19 female; mean age 21) was conducted. Subjects were tested under three conditions: fully rested, sleep deprived, and alcohol intoxicated - BrAC mean [SD] 25.95 µg [2.78]. Under each condition, subjects were tested before and after coffee ingestion. This involved driving simulation (Lane Change Task and Reaction Test) and subjective Likert scales (Karolinska Sleepiness Scale and driver impairment scale). Outcome measures included lane tracking adaptive mean deviation, reaction time, and subjective sleepiness and impairment ratings. RESULTS: Compared to alcohol, sleep deprived mean reaction times were slower (2.86 s vs. 2.34 s) and lateral control of the vehicle was reduced (lane tracking adaptive mean deviation: 0.5 vs. 0.3). Coffee did not produce an improvement when sleep deprived, and instead, performance deteriorated. Females were less impaired following sleep deprivation than males. Following prolonged wakefulness, the correlation between subjective impairment and actual performance was significant. CONCLUSIONS: It was concluded that sleep deprivation has a greater impact on driving performance than a BrAC of 22 µg/100mls of breath, as measured by driving simulation. Coffee is not an effective countermeasure for sleep deprived driving and drivers' ability to judge this impairment is suggested to be limited.

Shift length and working practices in UK hospital settings: An online survey of heads of midwifery.

OBJECTIVE: There is currently a lack of data that records how midwives are expected to work in hospital settings. The aim of this study was to determine the prevalence of 12-h shifts and current working practices of hospital-based midwives. DESIGN: An online survey conducted between December 2018 and March 2019. Descriptive data are summarised regionally and nationally. SETTING: NHS Trusts providing maternity services in hospital settings in the UK PARTICIPANTS: The link to the survey was emailed to Heads of Midwifery in 155 NHS Trusts FINDINGS: Responses were received from 94 of the 155 NHS Trusts (60.65%). Some responses included data for more than one hospital, so results are summarised for 97 hospitals. 12-h shifts were the most prevalent shift length, with only 4.1% of hospitals still routinely operating shorter shifts. 55% of hospitals limit the maximum number of consecutive shifts to three, but this can be influenced by different factors. More than half of midwives (55.67%) will be rostered to start a day shift within 24-h of finishing a night shift. 70% of hospitals do not currently record the number of midwives working beyond their contracted hours but 68% report formal methods of recording missed rest breaks. Regional differences were seen in the use of other personnel to support the midwifery workforce. CONCLUSIONS: Shift schedules and the lack of formal methods to record the number of midwives working beyond their contracted hours may be a cause for concern due to the potential impact on recovery times. Further research is required to explore how working practices may affect midwives and their ability to provide care for women and their babies.
