sleep performance workload

Jagdeep Johal, Andrew Dodd
BACKGROUND: With the introduction of resident duty hour restrictions and the resulting in-house trainee shortages, a long-term solution to ensure safe and efficient patient care is needed. One solution is the integration of nurse practitioners (NPs) and physician assistants (PAs) in a variety of health care settings. We sought to examine the use of NPs and PAs on surgical/trauma services and their effect on patient outcomes and resident workload. METHODS: We performed a systematic review of EMBASE, Medline, CINAHL, and the Cochrane Central Register of Controlled Trials...

Sleep has tremendous importance to organizations because of its relationship with employee performance, safety, health, and attitudes. Moreover, sleep is a malleable behavior that may be improved by individual and organizational changes. Despite the consequential and modifiable nature of sleep, little consensus exists regarding its conceptualization, and how the choice of conceptualization may impact relationships with organizational antecedents and outcomes. To offer a stronger foundation for future theory and research about employee sleep, this study calculated meta-analytic correlations of sleep quality and sleep quantity from 152 primary studies of sleep among workers in organizations...

The lack of sleep, both in quality and quantity, is an increasing problem in modern society, often related to workload and stress. A number of studies have addressed the effects of acute (total) sleep deprivation on postural control. However, up to date, the effects of chronic sleep deficits, either in quantity or quality, have not been analyzed. Thirty healthy adults participated in the study that consisted of registering activity with a wrist actigraph for more than a week before performing a series of postural control tests...

The timing of morning endurance competition may limit proper pre-race fueling and resulting performance. A nighttime, pre-sleep nutritional strategy could be an alternative method to target the metabolic and hydrating needs of the early morning athlete without compromising sleep or gastrointestinal comfort during exercise. Therefore, the purpose of this investigation was to examine the acute effects of pre-sleep chocolate milk (CM) ingestion on next-morning running performance, metabolism, and hydration status...

Night shifts expose anaesthesia trainees to the risk of fatigue and, potentially, fatigue-related performance impairment. This study examined the workload, fatigue and coping strategies of anaesthesia trainees during night shifts. A blinded survey-based study was undertaken at a major single centre metropolitan teaching hospital in Australia. All ten anaesthesia trainees who worked night shifts participated. The survey collected data on duration of night shifts, workload, and sleep patterns. Fatigue was assessed using the Karolinska Sleepiness Scale (KSS)...

Objective: This study sought to determine if mindfulness training (MT) has a measurable impact on stress and attentional control as measured by objective physiological and psychological means. Background: Periods of persistent, intensive work demands are known to compromise recovery and attentional capacity. The effects of 4-month MT on salivary cortisol and performance on 2 computer-based cognitive tasks were tested on a military helicopter unit exposed to a prolonged period of high workload. Methods: MT participants were compared to a wait list control group on levels of saliva cortisol and performance on a go-no go test and a test of stimulus-driven attentional capture...

A large proportion of crashes in road driving can be attributed to driver fatigue. Several types of fatigue are discussed, comprising sleep-related fatigue, active task-related fatigue (as a consequence of workload in demanding driving situations) as well as passive task-related fatigue (as related to monotonous driving situations). The present study investigated actual states of fatigue in a monotonous driving situation, using EEG measures and a long-lasting driving simulation experiment, in which drivers had to keep the vehicle on track by compensating crosswind of different strength...

BACKGROUND: Despite a gradual reduction in the workload during residency, 24-hour calls are still an integral part of most training programs. While sleep deprivation increases the risk propensity, the impact on medical risk taking has not been studied. OBJECTIVE: This study aimed to assess the clinical decision making and psychomotor performance of pediatric residents following a limited nap time during a 24-hour call. METHODS: A neurocognitive battery (IntegNeuro) and a medical decision questionnaire were completed by 44 pediatric residents at 2 time points: after a 24-hour call and following 3 nights with no calls (sleep ≥5 hours)...

Prior research shows that work on board vessels of the Royal Norwegian Navy (RNoN) is associated with noise exposure levels above recommended standards. Further, noise exposure has been found to impair cognitive performance in environmental, occupational, and experimental settings, although prior research in naval and maritime settings is sparse. The aim of this study was to evaluate cognitive performance after exposure to noise among personnel working on board vessels in the RNoN. Altogether 87 Navy personnel (80 men, 7 women; 31 ± 9 years) from 24 RNoN vessels were included...

Workers' fatigue is a significant problem in modern industry, largely because of high demand jobs, long duty periods, disruption of circadian rhythms, and accumulative sleep debt that are common in many industries. Fatigue is the end result of integration of multiple factors such as time awake, time of day, and workload. Then, the full understanding of circadian biologic clock, dynamics of transient and cumulative sleep loss, and recovery is required for effective management of workplace fatigue. It can be more investigated in a new field of sleep medicine called occupational sleep medicine...

Some heart failure (HF) patients develop ventilatory oscillation which is composed of exercise periodic breathing (EPB) and sleep apnea. The ventilatory oscillation is associated with exercise intolerance. This study employed an integrated monitoring system to elucidate the way of central and peripheral hemodynamic adaption responding to exercise. This study recruited 157 HF patients to perform exercise testing using a bicycle ergometer. A noninvasive bio-reactance device was adopted to measure cardiac hemodynamics, whereas a near-infrared spectroscopy (NIRS) was used to assess perfusion and O2 extraction in the frontal cerebral lobe (FC) and vastus lateralis muscle (VL) during exercise respectively...

OBJECTIVE: Shift workers regularly report sleep problems, fatigue, and the need for recuperative rest between shifts (intershift recovery). We sought to characterize intershift recovery among emergency medical services (EMS) workers and the role of worker demographics and work-related factors. METHODS: We combined cross-sectional survey data from two studies of EMS shift workers who completed standardized instruments, including the Occupational Fatigue Exhaustion Recovery (OFER) scale...

Sleep deprivation and/or a high workload situation can adversely affect driving performance, decreasing a driver's capacity to respond effectively in dangerous situations. In this context, to provide useful feedback and alert signals in real time to the drivers physiological and brain activities have been increasingly investigated in literature. In this study, we analyze the increase of cerebral workload and the insurgence of drowsiness during car driving in a simulated environment by using high resolution electroencephalographic techniques (EEG) as well as neurophysiologic variables such as heart rate (HR) and eye blinks rate (EBR)...

Disruption in police officers. In recent years there has been a widespread growth in services, available regardless of time or day organization (24/7 service) and a diffuse increase in their use, both in work and private lives, generally ignoring the importance of a regular sleep organization. Police officers - often need to work extended shifts and long hours under highly stressful conditions, which results in reduced levels of safety and operational effectiveness. In numerous studies, perceived stress has been found to correlate with both subjective and objective disturbances in sleep...

OBJECTIVE: It is unknown if aerobic exercise overloads or improves the cardiovascular system among workers with high occupational physical activity. This was investigated in a worksite randomized controlled trial (RCT) of aerobic exercise among cleaners. METHODS: We randomized 116 cleaners between 18-65 years. The aerobic exercise group (N=57) performed worksite aerobic exercise (30 minutes twice a week) and the reference group (N=59) received lectures. Cardiorespiratory fitness, blood pressure (BP) and diurnal heart rate (HR) for measuring aerobic workload [% HR reserve (% HRR)] were collected at baseline and after four months...

Work should be a source of health, pride, and happiness, in the sense of enhancing motivation and strengthening personal development. Healthy and motivated employees perform better and remain loyal to the company for a longer time. But, when the person constantly experiences high workload over a longer period of time and is not able to recover, then work may lead to prolonged negative effects and might cause serious illnesses like chronic stress disease. In this work, we present a solution for assessing the stress experience of people, using features derived from smartphones and wearable chest belts...

BACKGROUND: More than 15 years ago, the Institute of Medicine (IOM) identified medical error as a problem worthy of greater attention; in the wake of the IOM report, numerous changes were made to regulations to limit residents' duty hours. However, the effect of resident work-hour changes remains controversial within the field of orthopaedics. QUESTIONS/PURPOSES: We performed a systematic review to determine whether work-hour restrictions have measurably influenced quality-of-life measures, operative and technical skill development, resident surgical education, patient care outcomes (including mortality, morbidity, adverse events, sentinel events, complications), and surgeon and resident attitudes (such as perceived effect on learning and training experiences, personal benefit, direct clinical experience, clinical preparedness)...

INTRODUCTION: Flight timing is expected to influence pilot fatigue because it determines the part of the circadian body clock cycle that is traversed during a flight. However the effects of flight timing are not well-characterized because field studies typically focus on specific flights with a limited range of departure times and have small sample sizes. The present project combined data from four studies, including 13 long-range and ultra-long range out-and-back trips across a range of departure and arrival times (237 pilots in 4-person crews, 730 flight segments, 1-3 d layovers)...
