Implementing a 48 h EWTD-compliant rota for junior doctors in the UK does not compromise patients' safety: assessor-blind pilot comparison

The effects of resident work hours on well-being, performance, and education: A review from a Japanese perspective

This article examines the impact of working-hour restrictions on the well-being, performance, and education of medical residents in Japan. Despite Japan's plan to introduce new regulations for resident working hours by 2024, there is still an ongoing debate regarding their appropriateness. This review provides a comprehensive overview of the current regulations of resident working hours worldwide, with a specific focus on weekly hours. The varying regulations are highlighted, including the 80-hour-per-week regulation in the United States and the 48-h-per-week regulation in the European Union influencing other regions. The article also discusses the effectiveness of working-hour restrictions on residents' mental health, with shorter working hours having potentially greater benefits. However, the impacts on medical safety and resident education are mixed, and further reduction in working hours must be carefully considered to avoid adverse effects. The planned changes to working-hour limits for residents in Japan offer a unique opportunity to gain new evidence on the impact of such regulations, which will be of interest to policymakers and researchers worldwide.

Adapting shift work schedules for sleep quality, sleep duration, and sleepiness in shift workers

BACKGROUND

Shift work is associated with insufficient sleep, which can compromise worker alertness with ultimate effects on occupational health and safety. Adapting shift work schedules may reduce adverse occupational outcomes.

OBJECTIVES

To assess the effects of shift schedule adaptation on sleep quality, sleep duration, and sleepiness among shift workers.

SEARCH METHODS

We searched CENTRAL, PubMed, Embase, and eight other databases on 13 December 2020, and again on 20 April 2022, applying no language restrictions.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) and non-RCTs, including controlled before-after (CBA) trials, interrupted time series, and cross-over trials. Eligible trials evaluated any of the following shift schedule components. • Permanency of shifts • Regularity of shift changes • Direction of shift rotation • Speed of rotation • Shift duration • Timing of start of shifts • Distribution of shift schedule • Time off between shifts • Split shifts • Protected sleep • Worker participation We included studies that assessed sleep quality off-shift, sleep duration off-shift, or sleepiness during shifts.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened the titles and abstracts of the records recovered by the search, read through the full-text articles of potentially eligible studies, and extracted data. We assessed the risk of bias of included studies using the Cochrane risk of bias tool, with specific additional domains for non-randomised and cluster-randomised studies. For all stages, we resolved any disagreements by consulting a third review author. We presented the results by study design and combined clinically homogeneous studies in meta-analyses using random-effects models. We assessed the certainty of the evidence with GRADE.

MAIN RESULTS

We included 11 studies with a total of 2125 participants. One study was conducted in a laboratory setting and was not considered for drawing conclusions on intervention effects. The included studies investigated different and often multiple changes to shift schedule, and were heterogeneous with respect to outcome measurement. Forward versus backward rotation Three CBA trials (561 participants) investigated the effects of forward rotation versus backward rotation. Only one CBA trial provided sufficient data for the quantitative analysis; it provided very low-certainty evidence that forward rotation compared with backward rotation did not affect sleep quality measured with the Basic Nordic Sleep Questionnaire (BNSQ; mean difference (MD) -0.20 points, 95% confidence interval (CI) -2.28 to 1.89; 62 participants) or sleep duration off-shift (MD -0.21 hours, 95% CI -3.29 to 2.88; 62 participants). However, there was also very low-certainty evidence that forward rotation reduced sleepiness during shifts measured with the BNSQ (MD -1.24 points, 95% CI -2.24 to -0.24; 62 participants). Faster versus slower rotation Two CBA trials and one non-randomised cross-over trial (341 participants) evaluated faster versus slower shift rotation. We were able to meta-analyse data from two studies. There was low-certainty evidence of no difference in sleep quality off-shift (standardised mean difference (SMD) -0.01, 95% CI -0.26 to 0.23) and very low-certainty evidence that faster shift rotation reduced sleep duration off-shift (SMD -0.26, 95% CI -0.51 to -0.01; 2 studies, 282 participants). The SMD for sleep duration translated to an MD of 0.38 hours' less sleep per day (95% CI -0.74 to -0.01). One study provided very low-certainty evidence that faster rotations decreased sleepiness during shifts measured with the BNSQ (MD -1.24 points, 95% CI -2.24 to -0.24; 62 participants). Limited shift duration (16 hours) versus unlimited shift duration Two RCTs (760 participants) evaluated 80-hour workweeks with maximum daily shift duration of 16 hours versus workweeks without any daily shift duration limits. There was low-certainty evidence that the 16-hour limit increased sleep duration off-shift (SMD 0.50, 95% CI 0.21 to 0.78; which translated to an MD of 0.73 hours' more sleep per day, 95% CI 0.30 to 1.13; 2 RCTs, 760 participants) and moderate-certainty evidence that the 16-hour limit reduced sleepiness during shifts, measured with the Karolinska Sleepiness Scale (SMD -0.29, 95% CI -0.44 to -0.14; which translated to an MD of 0.37 fewer points, 95% CI -0.55 to -0.17; 2 RCTs, 716 participants). Shorter versus longer shifts One RCT, one CBA trial, and one non-randomised cross-over trial (692 participants) evaluated shorter shift duration (eight to 10 hours) versus longer shift duration (two to three hours longer). There was very low-certainty evidence of no difference in sleep quality (SMD -0.23, 95% CI -0.61 to 0.15; which translated to an MD of 0.13 points lower on a scale of 1 to 5; 2 studies, 111 participants) or sleep duration off-shift (SMD 0.18, 95% CI -0.17 to 0.54; which translated to an MD of 0.26 hours' less sleep per day; 2 studies, 121 participants). The RCT and the non-randomised cross-over study found that shorter shifts reduced sleepiness during shifts, while the CBA study found no effect on sleepiness. More compressed versus more spread out shift schedules One RCT and one CBA trial (346 participants) evaluated more compressed versus more spread out shift schedules. The CBA trial provided very low-certainty evidence of no difference between the groups in sleep quality off-shift (MD 0.31 points, 95% CI -0.53 to 1.15) and sleep duration off-shift (MD 0.52 hours, 95% CI -0.52 to 1.56).

AUTHORS' CONCLUSIONS

Forward and faster rotation may reduce sleepiness during shifts, and may make no difference to sleep quality, but the evidence is very uncertain. Very low-certainty evidence indicated that sleep duration off-shift decreases with faster rotation. Low-certainty evidence indicated that on-duty workweeks with shift duration limited to 16 hours increases sleep duration, with moderate-certainty evidence for minimal reductions in sleepiness. Changes in shift duration and compression of workweeks had no effect on sleep or sleepiness, but the evidence was of very low-certainty. No evidence is available for other shift schedule changes. There is a need for more high-quality studies (preferably RCTs) for all shift schedule interventions to draw conclusions on the effects of shift schedule adaptations on sleep and sleepiness in shift workers.

Work like a Doc: A comparison of regulations on residents' working hours in 14 high-income countries

BACKGROUND

Medical residents work long, continuous hours. Working in conditions of extreme fatigue has adverse effects on the quality and safety of care, and on residents' quality of life. Many countries have attempted to regulate residents' work hours.

OBJECTIVES

We aimed to review residents' work hours regulations in different countries with an emphasis on night shifts.

METHODS

Standardized qualitative data on residents' working hours were collected with the assistance of experts from 14 high-income countries through a questionnaire. An international comparative analysis was performed.

RESULTS

All countries reviewed limit the weekly working hours; North-American countries limit to 60-80 h, European countries limit to 48 h. In most countries, residents work 24 or 26 consecutive hours, but the number of long overnight shifts varies, ranging from two to ten. Many European countries face difficulties in complying with the weekly hour limit and allow opt-out contracts to exceed it.

CONCLUSIONS

In the countries analyzed, residents still work long hours. Attempts to limit the shift length or the weekly working hours resulted in modest improvements in residents' quality of life with mixed effects on quality of care and residents' education.

Impact of work schedules of senior resident physicians on patient and resident physician safety: nationwide, prospective cohort study

Objective

To determine whether long weekly work hours and shifts of extended duration (≥24 hours) are associated with adverse patient and physician safety outcomes in more senior resident physicians (postgraduate year 2 and above; PGY2+).

Design

Nationwide, prospective cohort study.

Setting

United States, conducted over eight academic years (2002-07, 2014-17).

Participants

4826 PGY2+ resident physicians who completed 38 702 monthly web based reports of their work hours and patient and resident safety outcomes.

Main outcome measures

Patient safety outcomes included medical errors, preventable adverse events, and fatal preventable adverse events. Resident physician health and safety outcomes included motor vehicle crashes, near miss crashes, occupational exposures to potentially contaminated blood or other bodily fluids, percutaneous injuries, and attentional failures. Data were analysed with mixed effects regression models that accounted for dependence of repeated measures and controlled for potential confounders.

Results

Working more than 48 hours per week was associated with an increased risk of self-reported medical errors, preventable adverse events, and fatal preventable adverse events as well as near miss crashes, occupational exposures, percutaneous injuries, and attentional failures (all P<0.001). Working between 60 and 70 hours per week was associated with a more than twice the risk of a medical error (odds ratio 2.36, 95% confidence interval 2.01 to 2.78) and almost three times the risk of preventable adverse events (2.93, 2.04 to 4.23) and fatal preventable adverse events (2.75, 1.23 to 6.12). Working one or more shifts of extended duration in a month while averaging no more than 80 weekly work hours was associated with an 84% increased risk of medical errors (1.84, 1.66 to 2.03), a 51% increased risk of preventable adverse events (1.51, 1.20 to 1.90), and an 85% increased risk of fatal preventable adverse events (1.85, 1.05 to 3.26). Similarly, working one or more shifts of extended duration in a month while averaging no more than 80 weekly work hours also increased the risk of near miss crashes (1.47, 1.32 to 1.63) and occupational exposures (1.17, 1.02 to 1.33).

Conclusions

These results indicate that exceeding 48 weekly work hours or working shifts of extended duration endangers even experienced (ie, PGY2+) resident physicians and their patients. These data suggest that regulatory bodies in the US and elsewhere should consider lowering weekly work hour limits, as the European Union has done, and eliminating shifts of extended duration to protect the more than 150 000 physicians training in the US and their patients.

Nurse rostering with fatigue modelling : Incorporating a validated sleep model with biological variations in nurse rostering

We use a real Nurse Rostering Problem and a validated model of human sleep to formulate the Nurse Rostering Problem with Fatigue. The fatigue modelling includes individual biologies, thus enabling personalised schedules for every nurse. We create an approximation of the sleep model in the form of a look-up table, enabling its incorporation into nurse rostering. The problem is solved using an algorithm that combines Mixed-Integer Programming and Constraint Programming with a Large Neighbourhood Search. A post-processing algorithm deals with errors, to produce feasible rosters minimising global fatigue. The results demonstrate the realism of protecting nurses from highly fatiguing schedules and ensuring the alertness of staff. We further demonstrate how minimally increased staffing levels enable lower fatigue, and find evidence to suggest biological complementarity among staff can be used to reduce fatigue. We also demonstrate how tailoring shifts to nurses' biology reduces the overall fatigue of the team, which means managers must grapple with the issue of fairness in rostering.

Nigerian resident doctors' work schedule: A national study

Background and Aim

The deleterious effects of Resident Doctors' (RDs') long duty hours are well documented. Driven by concerns over the physician's well-being and patient safety, the RDs' duty hours in many developed countries have been capped. However, in Nigeria and many African countries, there are no official regulations on work hours of RDs. This study evaluated the work schedule of Nigerian RDs and its impact on their wellbeing and patient safety.

Subjects and Methods

A national survey of 1105 Nigerian RDs from all specialties in 59 training institutions was conducted. With an electronic questionnaire designed using Google Forms, data on the work activities of RDs were obtained and analyzed using the IBM SPSS software version 24. The associations were compared using Chi-squared test with the level of significance set at < 0.05.

Results

The mean weekly duty hours (h) of the RDs was 106.5 ± 50.4. Surgical residents worked significantly longer hours than non-surgical residents (122.7 ± 34.2 h vs 100.0 ± 43.9 h; P < 0.001). The modal on-call frequency was two weekday on-calls per week (474, 42.9%) and two weekend on-calls per month (495, 44.8%), with the majority of RDs working continuously for up to 24 hours during weekday on-calls (854, 77.3%) and 48-72 hours during weekend on-calls (568, 51.4%), sleeping for an average of only four hours during these on-calls. The majority of RDs had post-call clinical responsibilities (975, 88.2%) and desired official regulation of duty hours (1,031, 93.3%).

Conclusion

The duty hours of Nigerian RDs are currently long and unregulated. There is an urgent need to regulate them for patient and physician safety.

Self in medicine: Determinants of physician well-being and future directions in improving wellness

CONTEXT

Medicine, a profession dedicated to the wellness of patients, is struggling with a crisis of physician and trainee wellness. Physicians and trainees are burning out at alarming rates. Historically, medicine has been characterised by challenging working conditions and inattention to physician wellness and self-care. Healthy physicians are better at promoting wellness to their patients, and physicians who are suffering from burnout can deliver compromised patient care.

DISCUSSION

In recent years, research has increasingly focused on the causes of unwellness among doctors, and a broad range of health determinants have been identified. Studies of interventions for improving trainee and physician wellness have identified individual-focused and organisational approaches that can address the root causes of burnout. Insights from the corporate workplace may help guide interventions. Strategies for addressing physician burnout and improving wellness will involve innovative and multifaceted approaches. Despite a growing emphasis of physician wellness in the literature, implementation of wellness interventions is lagging, and quality improvement methods can address these challenges.

CONCLUSION

Physician wellness is a shared responsibility among doctors, health care organisations and governing bodies. Addressing burnout and improving physician wellness will require transformational change and the embracement of a culture of wellness in medicine. Quality improvement methods are the next step in identifying effective wellness interventions and the targeted groups of physicians and trainees who will most benefit.

Trainee Experience in Simulation-Based Education of Open Vascular Surgery

BACKGROUND

Simulation continues to be an important adjunct to vascular surgery training, yet the optimal implementation of simulation to complement conventional surgical training continues to evolve. This study aims to find areas for improvement in current simulation-based training of open vascular skills by characterizing the experience of vascular trainees attending a national simulation-based course.

METHOD

This was a survey study conducted at the simulation course of the Annual UCLA/SVS Symposium: A Comprehensive Review and Update of What's New in Vascular and Endovascular Surgery, a national vascular surgery meeting. The survey consisted of 17 questions and was administered on paper or electronically via the Audience Response System, before the start of the course. The survey assessed the participants' experience in formal training, simulation training, and comfort with open surgical procedures.

RESULTS

Between 2013 and 2018, the survey was completed by 150 participants of which 65% were vascular fellows. Only 48% of the participants had formal training in suturing and surgical instruments. Most participants had formal training in basic vascular techniques and advanced vascular operations. In 71%, simulation was incorporated into basic technique training and 60% in open surgical training. Simulation training was most commonly utilized in learning anastomotic techniques and open abdominal aortic aneurysm repair. Simulation skills were deemed translatable to the operating room by 59% of participants. Most participants were comfortable performing open vascular procedures. However, 68% of participants were uncomfortable performing an abdominal aortic aneurysm repair.

CONCLUSIONS

There continues to be a significant portion of trainees who do not undergo a simulation-based education. Current simulation training is being targeted to meet trainee needs in open vascular surgery, specifically open aneurysm repair. Nonetheless, trainees continue to have doubts regarding applicability of simulation-based skills to the operating theater. Further studies investigating access to simulation education as well as its translatability are needed.

The Effect of Blue-Enriched Lighting on Medical Error Rate in a University Hospital ICU

BACKGROUND

Fatigue-related errors that occur during patient care impose a tremendous socioeconomic impact on the health care system. Blue-enriched light has been shown to promote alertness and attention. The present study tested whether blue-enriched light can help to reduce medical errors in a university hospital adult ICU.

METHODS

In this interventional study, a blue-enriched white light emitting diode was used to enhance traditional fluorescent light at the nurse workstation and common areas in the ICU. Medical errors were identified retrospectively using an established two-step surveillance process. Suspected incidents of potential errors detected on nurse chart review were subsequently reviewed by two physicians blinded to lighting conditions, who made final classifications. Error rates were compared between the preintervention fluorescent and postintervention blue-enriched lighting conditions using Poisson regression.

RESULTS

The study included a total of 1,073 ICU admissions, 522 under traditional and 551 under interventional lighting (age range 17-97 years, mean age ± standard deviation 58.5 ± 15.8). No difference was found in overall medical error rate (harmful and non-harmful) pre- vs. postintervention, 45.5 vs. 42.7 per 1,000 patient-days (rate ratio: 0.94, 95% confidence interval = 0.71-1.23, p = 0.64).

CONCLUSION

Interventional lighting did not have an effect on overall medical error rate. The study was likely underpowered to detect the 25% error reduction predicted. Future studies are required that are powered to assess more modest effects for lighting to reduce the risk of fatigue-related medical errors and errors of differing severity.

Effects on resident work hours, sleep duration, and work experience in a randomized order safety trial evaluating resident-physician schedules (ROSTERS)

STUDY OBJECTIVES

We compared resident physician work hours and sleep in a multicenter clustered-randomized crossover clinical trial that randomized resident physicians to an Extended Duration Work Roster (EDWR) with extended-duration (≥24 hr) shifts or a Rapidly Cycling Work Roster (RCWR), in which scheduled shift lengths were limited to 16 or fewer consecutive hours.

METHODS

Three hundred two resident physicians were enrolled and completed 370 1 month pediatric intensive care unit rotations in six US academic medical centers. Sleep was objectively estimated with wrist-worn actigraphs. Work hours and subjective sleep data were collected via daily electronic diary.

RESULTS

Resident physicians worked fewer total hours per week during the RCWR compared with the EDWR (61.9 ± 4.8 versus 68.4 ± 7.4, respectively; p < 0.0001). During the RCWR, 73% of work hours occurred within shifts of ≤16 consecutive hours. In contrast, during the EDWR, 38% of work hours occurred on shifts of ≤16 consecutive hours. Resident physicians obtained significantly more sleep per week on the RCWR (52.9 ± 6.0 hr) compared with the EDWR (49.1 ± 5.8 hr, p < 0.0001). The percentage of 24 hr intervals with less than 4 hr of actigraphically measured sleep was 9% on the RCWR and 25% on the EDWR (p < 0.0001).

CONCLUSIONS

RCWRs were effective in reducing weekly work hours and the occurrence of >16 consecutive hour shifts, and improving sleep duration of resident physicians. Although inclusion of the six operational healthcare sites increases the generalizability of these findings, there was heterogeneity in schedule implementation. Additional research is needed to optimize scheduling practices allowing for sufficient sleep prior to all work shifts.Clinical Trial: Multicenter Clinical Trial of Limiting Resident Work Hours on ICU Patient Safety (ROSTERS), https://clinicaltrials.gov/ct2/show/NCT02134847.

Perseverance, faith and stoicism: a qualitative study of medical student perspectives on managing fatigue

CONTEXT

Fatigue risk management (FRM) strategies offer a potential solution to the widespread problem of fatigued trainees in the clinical workplace. These strategies assume a shared perception that fatigue is hazardous. Despite the growing body of evidence suggesting that fatigue leads to burnout and medical errors, previous research suggests that residents perceive fatigue as a personal, surmountable burden rather than an occupational hazard. Before we can implement FRM, we need a better understanding of when and how such problematic notions of fatigue are adopted by medical trainees. Thus, we sought to explore how third-year medical students understand and manage the workplace fatigue they experience during their first year of clinical rotations.

METHODS

A total of 22 third-year medical students participated in semi-structured interviews exploring their perspectives of workplace fatigue. Data collection and analysis occurred iteratively in keeping with constructivist grounded theory methodology and were informed by theoretical sampling to sufficiency.

RESULTS

Our participants described unprecedented levels of sleep deprivation combined with uncertainty and confusion that led to significant fatigue during training. Drawing on their workplace experience, trainees believed that fatigue posed three distinct threats, which evoked different coping strategies: (i) threat to personal health, managed by perseverance; (ii) threat to patients, managed by faith in the system, and (iii) threat to professional reputation, managed by stoicism.

CONCLUSIONS

Our findings highlight how senior medical students grapple with fatigue, as they understand it, within a training context in which they are expected to deny the impact of their fatigue on patients and themselves. Despite empirical evidence to the contrary, the prevailing assumption amongst our participants is that an ability to withstand sleep deprivation without impairment will develop naturally over time. Efforts to implement FRM strategies will need to address this assumption if these strategies are to be successfully taken up and effective.

Healthy working time arrangements for healthcare personnel and patients: a systematic literature review

BACKGROUND

A number of working time arrangements have been linked to negative consequences for both health personnel and their patients. A common hypothesis put forth to explain these findings suggests that certain working time arrangements lead to negative patient consequences due to the adverse impact they have on employee health. The purpose of this study is to use systematic reviews to investigate whether employee health explains the relationship between working time arrangements and patient safety.

METHODS

A systematic literature review was performed including published reviews and original studies from MEDLINE, PsycINFO, Cinahl and Web of Science investigating working time arrangements for healthcare personnel, employee health and patient safety. In addition, we screened reference lists of identified reviews. Two reviewers independently identified relevant publications according to inclusion criteria, extracted findings and assessed quality.

RESULTS

Six thousand nine hundred thirty papers were identified, of which 52 studies met our criteria. Articles were categorized into five groups according to how they approached the research question: 1) independent analyses of relationship between working time arrangements and employee health, and of working time arrangements and patient safety (5 studies); 2) relationship between working time arrangements on both employee health and patient safety (21 studies); 3) working time arrangements and employee health as two explanatory variables for patient safety (8 studies); 4) combinations of the above analyses (7 studies); 5) other relevant studies (5 studies). Studies that find that working time is detrimental to employee health, generally also find detrimental results for patient safety. This is particularly shown through increases in errors by health personnel. When controlling for employee health, the relationship between working time arrangements and patient safety is reduced, but still significant.

CONCLUSIONS

Results suggest that employee health partially (but not completely) mediates the relationship between working time arrangements and patient safety. However, there is a lack of studies directly investigating employee health as a mediator between working time arrangements and patient safety. Future studies should address this research gap.

The Impact of Shift Work on Sleep, Alertness and Performance in Healthcare Workers

Shift work is associated with impaired alertness and performance due to sleep loss and circadian misalignment. This study examined sleep between shift types (day, evening, night), and alertness and performance during day and night shifts in 52 intensive care workers. Sleep and wake duration between shifts were evaluated using wrist actigraphs and diaries. Subjective sleepiness (Karolinska Sleepiness Scale, KSS) and Psychomotor Vigilance Test (PVT) performance were examined during day shift, and on the first and subsequent night shifts (3^rd, 4^th or 5^th). Circadian phase was assessed using urinary 6-sulphatoxymelatonin rhythms. Sleep was most restricted between consecutive night shifts (5.74 ± 1.30 h), consecutive day shifts (5.83 ± 0.92 h) and between evening and day shifts (5.20 ± 0.90 h). KSS and PVT mean reaction times were higher at the end of the first and subsequent night shift compared to day shift, with KSS highest at the end of the first night. On nights, working during the circadian acrophase of the urinary melatonin rhythm led to poorer outcomes on the KSS and PVT. In rotating shift workers, early day shifts can be associated with similar sleep restriction to night shifts, particularly when scheduled immediately following an evening shift. Alertness and performance remain most impaired during night shifts given the lack of circadian adaptation to night work. Although healthcare workers perceive themselves to be less alert on the first night shift compared to subsequent night shifts, objective performance is equally impaired on subsequent nights.

Making Memories: Why Time Matters

In the last decade advances in human neuroscience have identified the critical importance of time in creating long-term memories. Circadian neuroscience has established biological time functions via cellular clocks regulated by photosensitive retinal ganglion cells and the suprachiasmatic nuclei. Individuals have different circadian clocks depending on their chronotypes that vary with genetic, age, and sex. In contrast, social time is determined by time zones, daylight savings time, and education and employment hours. Social time and circadian time differences can lead to circadian desynchronization, sleep deprivation, health problems, and poor cognitive performance. Synchronizing social time to circadian biology leads to better health and learning, as demonstrated in adolescent education. In-day making memories of complex bodies of structured information in education is organized in social time and uses many different learning techniques. Research in the neuroscience of long-term memory (LTM) has demonstrated in-day time spaced learning patterns of three repetitions of information separated by two rest periods are effective in making memories in mammals and humans. This time pattern is based on the intracellular processes required in synaptic plasticity. Circadian desynchronization, sleep deprivation, and memory consolidation in sleep are less well-understood, though there has been considerable progress in neuroscience research in the last decade. The interplay of circadian, in-day and sleep neuroscience research are creating an understanding of making memories in the first 24-h that has already led to interventions that can improve health and learning.

Survey of occupational fatigue in anaesthetists in Australia and New Zealand

Occupational fatigue in anaesthetists is recognised as a patient safety risk. Better understanding of the issues surrounding their fatigue is needed. This study aimed to ascertain the sources and effects of occupational fatigue amongst anaesthetists in Australia and New Zealand. An anonymous online survey was sent to 979 anaesthetists. The response rate was 38.0%. Most participants reported regularly working over 40 hours per week; men reported five more hours per week than women. Stated contributors to fatigue included long work hours, mental strain at work, and personal and family demands. Fatigue-related behaviour was reported more by men (OR [odds ratio]=2.6) and less by respondents reporting eight or more hours of sleep before work (OR=0.6). Reporting at least one instance of less than five hours off between shifts was predictive of falling asleep while administering an anaesthetic (OR=1.6). More data are required to support practices and policies that promote more time off between work periods and increased time for sleep to reduce risk of fatigue.

Fatigue in Residency Education: Understanding the Influence of Work Hours Regulations in Europe

PURPOSE

Although one proposed solution to the problem of fatigued medical trainees is the implementation of work hours regulations, concerns about the effectiveness of these regulations are growing. Canada remains one of the few Western jurisdictions without legislated regulation. Recent research suggests that fatigue is a complex social construct, rather than simply a lack of sleep; thus, the authors explored how regulations and fatigue are understood in countries with established work hours frameworks to better inform other jurisdictions looking to address trainee fatigue.

METHOD

Using constructivist grounded theory methodology, the authors conducted individual, semistructured interviews in 2015-2016 with 13 postgraduate medical trainees from four European countries with established work hours regulations. Data collection and analysis proceeded iteratively, and the authors used a constant comparative approach to analysis.

RESULTS

Trainees reported that they were commonly fatigued and that they violated the work hours restrictions for various reasons, including educational pursuits. Although they understood the regulations were legislated specifically to ensure safe patient care and optimize trainee well-being, they also described implicit meanings (e.g., monitoring for trainee efficiency) and unintended consequences (e.g., losing a sense of vocation).

CONCLUSIONS

Work hours regulations carry multiple, conflicting meanings for trainees that are captured by three predominant rhetorics: the rhetoric of patient safety, of well-being, and of efficiency. Tensions within each of those rhetorics reveal that managing fatigue within clinical training environments is complex. These findings suggest that straightforward solutions are unlikely to solve the problem of fatigue, assure patient safety, and improve trainee well-being.

Resident duty hour modification affects perceptions in medical education, general wellness, and ability to provide patient care

BACKGROUND

Resident duty hours have recently been under criticism, with concerns for resident and patient well-being. Historically, call shifts have been long, and some residency training programs have now restricted shift lengths. Data and opinions about the effects of such restrictions are conflicting. The Internal Medicine Residency Program at Dalhousie University recently moved from a traditional call structure to a day float/night float system. This study evaluated how this change in duty hours affected resident perceptions in several key domains.

METHODS

Senior residents from an internal medicine training program in Canada responded to an anonymous online survey immediately before and 6 months after the implementation of duty hour reform. The survey contained questions relating to three major domains: resident wellness, ability to deliver quality health care, and medical education experience. Mean pre- and post-intervention scores were compared using the t-test for paired samples.

RESULTS

Twenty-three of 27 (85 %) senior residents completed both pre- and post-reform surveys. Residents perceived significant changes in many domains with duty hour reform. These included improved general wellness, less exposure to personal harm, fewer feelings of isolation, less potential for error, improvement in clinical skills expertise, increased work efficiency, more successful teaching, increased proficiency in medical skills, more successful learning, and fewer rotation disruptions.

CONCLUSIONS

Senior residents in a Canadian internal medicine training program perceived significant benefits in medical education experience, ability to deliver healthcare, and resident wellness after implementation of duty hour reform.

A Narrative Review of High-Quality Literature on the Effects of Resident Duty Hours Reforms

PURPOSE

To summarize current high-quality studies evaluating the effect and efficacy of resident duty hours reforms (DHRs) on patient safety and resident education and well-being.

METHOD

The authors searched PubMed and Medline in August 2012 and again in May 2013 for literature (1987-2013) about the effects of DHRs. They assessed the quality of articles using the Medical Education Research Study Quality Instrument (MERSQI) scoring system. They considered randomized controlled trials (RCTs), partial RCTs, and all studies with a MERSQI score ≥ 14 to be "high-quality" methodology studies.

RESULTS

A total of 72 high-quality studies met inclusion criteria. Most studies showed no change or slight improvement in mortality and complication rates after DHRs. Resident well-being was generally improved, but there was a perceived negative impact on education (knowledge acquisition, skills, and cognitive performance) following DHRs. Eleven high-quality studies assessed the impact of DHR interventions; all reported a neutral to positive impact. Seven high-quality studies assessed costs associated with DHRs and demonstrated an increase in hospital costs.

CONCLUSIONS

The results of most studies that allow enough time for DHR interventions to take effect suggest a benefit to patient safety and resident well-being, but the effect on the quality of training remains unknown. Additional methodologically sound studies on the impact of DHRs are necessary. Priorities for future research include approaches to optimizing education and clinical proficiency and studies on the effect of intervention strategies on both education and patient safety. Such studies will provide additional information to help improve duty hours policies.

The impact of work time control on physicians' sleep and well-being

Physicians' work schedules are an important determinant of their own wellbeing and that of their patients. This study considers whether allowing physicians control over their work hours ameliorates the effects of demanding work schedules. A questionnaire was completed by hospital physicians regarding their work hours (exposure to long shifts, short inter-shift intervals, weekend duties, night duties, unpaid overtime; and work time control), sleep (quantity and disturbance) and wellbeing (burnout, stress and fatigue). Work time control moderated the negative impact that frequent night working had upon sleep quantity and sleep disturbance. For participants who never worked long shifts, work time control was associated with fewer short sleeps, but this was not the case for those who did work long shifts. Optimizing the balance between schedule flexibility and patient needs could enhance physicians' sleep when working the night shift, thereby reducing their levels of fatigue and enhancing patient care.

Dilemmas of a rota: Google's solution

Doctors take many forms of leave to further career training. Many hospital rotas omit these and are not updated frequently to reflect swaps in on-call duties. As a result, confusion arises with reduced staffing levels leading to sub-optimal patient care. Using Google Sheets, rota's can be modified to be team specific, remotely accessed, and edited by any device with an internet connection and web browser. A qualitative pre and post-implementation questionnaire assessed the usefulness of the online rota.

The rota was trialled on a surgical and medical team containing foundation year, core medical, core surgical, and registrar trainees. The respective surgical and medical rotas were copied, modified and pasted into a Google Sheet to contain only team specific information including all forms of leave. A link was emailed allowing teams to access and edit the rota. Post-implementation questionnaire 90% (n=10) stated they could access it remotely and 100% felt the new rota was very easy to use. Finally, 80% stated the Google Doc rota was a definite improvement on the old trust rota.

The rota was then trialled on an ITU SHO rota (n=8). The results were reproducible with 88% feeling it addressed their requirements and stating it was an improvement on their old rota. As a result of the implementation appropriate staffing levels were maintained on the ward. The key advantages of the Google rota are that it included all forms of leave and helped ensure adequate staffing levels on the ward. The remote nature means easy access even if off-site and can be viewed easier on smart phones. The different privacy settings ensure security of document. The rota is updated in real-time giving an accurate representation of staffing levels – vital for service managers. The software is free to use, allowing it to work within current hospital IT framework.

Clinical criteria to screen for inpatient diagnostic errors: a scoping review

Diagnostic errors are common and costly, but difficult to detect. "Trigger" tools have promise to facilitate detection, but have not been applied specifically for inpatient diagnostic error. We performed a scoping review to collate all individual "trigger" criteria that have been developed or validated that may indicate that an inpatient diagnostic error has occurred. We searched three databases and screened 8568 titles and abstracts to ultimately include 33 articles. We also developed a conceptual framework of diagnostic error outcomes using real clinical scenarios, and used it to categorize the extracted criteria. Of the multiple criteria we found related to inpatient diagnostic error and amenable to automated detection, the most common were death, transfer to a higher level of care, arrest or "code", and prolonged length of hospital stay. Several others, such as abrupt stoppage of multiple medications or change in procedure, may also be useful. Validation for general adverse event detection was done in 15 studies, but only one performed validation for diagnostic error specifically. Automated detection was used in only two studies. These criteria may be useful for developing diagnostic error detection tools.

Organizational interventions in response to duty hour reforms

BACKGROUND

Changes in resident duty hours in Europe and North America have had a major impact on the internal organizational dynamics of health care organizations. This paper examines, and assesses the impact of, organizational interventions that were a direct response to these duty hour reforms.

METHODS

The academic literature was searched through the SCOPUS database using the search terms "resident duty hours" and "European Working Time Directive," together with terms related to organizational factors. The search was limited to English-language literature published between January 2003 and January 2012. Studies were included if they reported an organizational intervention and measured an organizational outcome.

RESULTS

Twenty-five articles were included from the United States (n=18), the United Kingdom (n=5), Hong Kong (n=1), and Australia (n=1). They all described single-site projects; the majority used post-intervention surveys (n=15) and audit techniques (n=4). The studies assessed organizational measures, including relationships among staff, work satisfaction, continuity of care, workflow, compliance, workload, and cost. Interventions included using new technologies to improve handovers and communications, changing staff mixes, and introducing new shift structures, all of which had varying effects on the organizational measures listed previously.

CONCLUSIONS

Little research has assessed the organizational impact of duty hour reforms; however, the literature reviewed demonstrates that many organizations are using new technologies, new personnel, and revised and innovative shift structures to compensate for reduced resident coverage and to decrease the risk of limited continuity of care. Future research in this area should focus on both micro (e.g., use of technology, shift changes, staff mix) and macro (e.g., culture, leadership support) organizational aspects to aid in our understanding of how best to respond to these duty hour reforms.

UK doctors' views on the implementation of the European Working Time Directive as applied to medical practice: a qualitative analysis

OBJECTIVES

To report on what doctors at very different levels of seniority wrote, in their own words, about their concerns about the European Working Time Directive (EWTD) and its implementation in the National Health Service (NHS).

DESIGN

All medical school graduates from 1993, 2005 and 2009 were surveyed by post and email in 2010.

SETTING

The UK.

METHODS

Using qualitative methods, we analysed free-text responses made in 2010, towards the end of the first year of full EWTD implementation, of three cohorts of the UK medical graduates (graduates of 1993, 2005 and 2009), surveyed as part of the UK Medical Careers Research Group's schedule of multipurpose longitudinal surveys of doctors.

RESULTS

Of 2459 respondents who gave free-text comments, 279 (11%) made unprompted reference to the EWTD; 270 of the 279 comments were broadly critical. Key themes to emerge included frequent dissociation between rotas and actual hours worked, adverse effects on training opportunities and quality, concerns about patient safety, lowering of morale and job satisfaction, and attempts reportedly made in some hospitals to persuade junior doctors to collude in the inaccurate reporting of compliance.

CONCLUSIONS

Further work is needed to determine whether problems perceived with the EWTD, when they occur, are attributable to the EWTD itself, and shortened working hours, or to the way that it has been implemented in some hospitals.

Training for the future NHS: training junior doctors in the United Kingdom within the 48-hour European working time directive

Since August 2009, the National Health Service of the United Kingdom has faced the challenge of delivering training for junior doctors within a 48-hour working week, as stipulated by the European Working Time Directive and legislated in the UK by the Working Time Regulations 1998. Since that time, widespread concern has been expressed about the impact of restricted duty hours on the quality of postgraduate medical training in the UK, particularly in the "craft" specialties--that is, those disciplines in which trainees develop practical skills that are best learned through direct experience with patients. At the same time, specialist training in the UK has experienced considerable change since 2007 with the introduction of competency-based specialty curricula, workplace-based assessment, and the annual review of competency progression. The challenges presented by the reduction of duty hours include increased pressure on doctors-in-training to provide service during evening and overnight hours, reduced interaction with supervisors, and reduced opportunities for learning. This paper explores these challenges and proposes potential responses with respect to the reorganization of training and service provision.

Sleep deprivation in resident physicians, work hour limitations, and related outcomes: a systematic review of the literature

Extended work hours, interrupted sleep, and shift work are integral parts of medical training among all specialties. The need for 24-hour patient care coverage and economic factors have resulted in prolonged work hours for resident physicians. This has traditionally been thought to enhance medical educational experience. These long and erratic work hours lead to acute and chronic sleep deprivation and poor sleep quality, resulting in numerous adverse consequences. Impairments may occur in several domains, including attention, cognition, motor skills, and mood. Resident performance, professionalism, safety, and well-being are affected by sleep deprivation, causing potentially adverse implications for patient care. Studies have shown adverse health consequences, motor vehicle accidents, increased alcohol and medication use, and serious medical errors to occur in association with both sleep deprivation and shift work. Resident work hour limitations have been mandated by the Accreditation Council for Graduate Medical Education in response to patient safety concerns. Studies evaluating the impact of these regulations on resident physicians have generated conflicting reports on patient outcomes, demonstrating only a modest increase in sleep duration for resident physicians, along with negative perceptions regarding their education. This literature review summarizes research on the effects of sleep deprivation and shift work, and examines current literature on the impact of recent work hour limitations on resident physicians and patient-related outcomes.

Shift work and vascular events: systematic review and meta-analysis

OBJECTIVE

To synthesise the association of shift work with major vascular events as reported in the literature.

DATA SOURCES

Systematic searches of major bibliographic databases, contact with experts in the field, and review of reference lists of primary articles, review papers, and guidelines.

STUDY SELECTION

Observational studies that reported risk ratios for vascular morbidity, vascular mortality, or all cause mortality in relation to shift work were included; control groups could be non-shift ("day") workers or the general population.

DATA EXTRACTION

Study quality was assessed with the Downs and Black scale for observational studies. The three primary outcomes were myocardial infarction, ischaemic stroke, and any coronary event. Heterogeneity was measured with the I(2) statistic and computed random effects models.

RESULTS

34 studies in 2,011,935 people were identified. Shift work was associated with myocardial infarction (risk ratio 1.23, 95% confidence interval 1.15 to 1.31; I(2)=0) and ischaemic stroke (1.05, 1.01 to 1.09; I(2)=0). Coronary events were also increased (risk ratio 1.24, 1.10 to 1.39), albeit with significant heterogeneity across studies (I(2)=85%). Pooled risk ratios were significant for both unadjusted analyses and analyses adjusted for risk factors. All shift work schedules with the exception of evening shifts were associated with a statistically higher risk of coronary events. Shift work was not associated with increased rates of mortality (whether vascular cause specific or overall). Presence or absence of adjustment for smoking and socioeconomic status was not a source of heterogeneity in the primary studies. 6598 myocardial infarctions, 17,359 coronary events, and 1854 ischaemic strokes occurred. On the basis of the Canadian prevalence of shift work of 32.8%, the population attributable risks related to shift work were 7.0% for myocardial infarction, 7.3% for all coronary events, and 1.6% for ischaemic stroke.

CONCLUSIONS

Shift work is associated with vascular events, which may have implications for public policy and occupational medicine.

Resident work hour restrictions do not improve patient safety in surgery: a critical appraisal based on 7 years of experience in Switzerland

In 2005 the Swiss government implemented new work-hour limitations for all residency programs in Switzerland, including a 50-hour weekly limit. The reduction in the working hours of doctors in training implicate an increase in their rest time and suggest an amelioration of doctors' clinical performance and consequently in patients' outcomes and safety - which was not detectable in a preliminary study at a large referral center in Switzerland. It remains elusive why work-hour restrictions did not improve patient safety. We are well advised to thoroughly examine and eliminate the known adverse effects of reduced work-hours to improve our patients' safety.

Excessive Daytime Sleepiness, Sleep Hygiene, and Work Hours Among Medical Residents in India

The purpose of this study was to examine the relationship between sleep hygiene, excessive daytime sleepiness and work hours among resident physicians in Chandigarh, India. Data were collected from 350 volunteering junior resident doctors and included sociodemographic variables, excessive daytime sleepiness (EDS) as measured by the Epworth Sleepiness Scale (ESS), sleep hygiene as measured by the Sleep Hygiene Index and hours worked. Almost half of the resident physicians studied reported a problem of EDS and maladaptive sleep hygiene practices. Physicians working more than 80 hours per week and physicians with more maladaptive sleep behaviours were much more likely to report EDS. The authors propose that sleep hygiene and number of hours slept should be considered as EDS prevention and treatment strategies, especially for physicians working less than 80 hours per week. The authors also propose that the most salient intervention for physicians working more than 80 hours per week is one of workplace advocacy, where the government is encouraged to adopt legally binding guidelines as seen in other countries.

Pediatric residents' perspectives on reducing work hours and lengthening residency: a national survey

OBJECTIVE

In 2011, the Accreditation Council on Graduate Medical Education increased restrictions on resident duty-hours. Additional changes have been considered, including greater work-hours restrictions and lengthening residency. Program directors tend to oppose further restrictions; however, residents' views are unclear. We sought to determine whether residents support these proposals, and if so why.

METHODS

We surveyed US pediatric residents from a probability sample of 58 residency programs. We used multivariate logistic regression to determine predictors of support for (1) a 56-hour workweek and (2) the addition of 1 year to residency to achieve a 56-hour week.

RESULTS

Fifty-seven percent of sampled residents participated (n = 1469). Forty-one percent of respondents supported a 56-hour week, with 28% neutral and 31% opposed. Twenty-three percent of all residents would be willing to lengthen training to reduce hours. The primary predictors of support for a 56-hour week were beliefs that it would improve education (odds ratio [OR] 8.6, P < .001) and quality of life (OR 8.7, P < .001); those who believed patient care would suffer were less likely to support it (OR 0.10, P < .001). Believing in benefits to education without decrement to patient care also predicted support for a 56-hour-week/4-year program.

CONCLUSIONS

Pediatric residents who support further reductions in work-hours believe reductions have positive effects on patient care, education, and quality of life. Most would not lengthen training to reduce hours, but a minority prefers this schedule. If evidence mounts showing that reducing work-hours benefits education and patient care, pediatric residents' support for the additional year may grow.

12-h or 8-h shifts? It depends

Since 12-h shifts were first implemented, the question has been asked - are 'twelves' better than 'eights'? People trying to answer this question invariably refer to the limited literature at their disposal, often piecemeal, small-scale studies comparing 8-h versus 12-h shifts in isolated groups of workers in which many other factors vary concurrently. The narrow perspective and sometimes 'vested interests' of the organizations, researchers, publishers and individual workers can influence both the choice of measures, the analysis of results and their interpretation. The current review suggests that it is not sufficient to evaluate a shift pattern on the basis of a single dimension of a working time arrangement, such as shift length. Numerous factors associated with the work practice influence the outcome of a shift pattern including start times, pattern of shifts and amount of overtime. Moreover, the type of work being done and the demographics or characteristics of the workforce are additional mediating factors. Finally, and perhaps most critically, the relative importance assigned to different outcome measures is an important consideration. There are situations where total sleep time might increase following a change to 12-h shifts, whereas domestic life for some workers may deteriorate. Additionally, safety measures may show improvements on 8-h shifts but physical or psychological health outcomes may be worse. The myriad combinations of work pattern, work task, worker and outcome measure under investigation mean that the best way to take account of these complexities may be to use an approach that manages 'system' risk. Given the non-linearities in the system, and the fact that current approaches either ignore, or privilege a subset of outcomes, it is perhaps more appropriate to conceptualize working time arrangements as an 'ecosystem' and to address the risks in the overall system as opposed to a single dimension such as shift length.

Is 48 hours enough for Obstetrics and Gynaecology training in Europe?

The European Working Time Directive, implemented by the European Union (EU) in 1993, was adopted in the medical profession to improve patient safety as well as the working lives of doctors. The Directive reduced the average amount of hours trainee doctors worked to 48 hours per week. However, its adoption has varied throughout the EU. Its potential effect on both the quality and total amount of hours of -training has caused concern. This monograph presents data on Obstetrics and Gynaecology training in Europe obtained from several of the European Network of Trainees in Obstetrics & Gynaecology's (ENTOG) surveys. The monograph demonstrates large variations in training and explains the difficulties in ascertaining whether 48 hours of training a week is sufficient to become an Obstetrics and Gynaecology specialist in Europe.

Ward rounds: missed learning opportunities in diagnostic changes?

BACKGROUND

The introduction of the European Working Time Directive has resulted in the on-call general surgery junior doctor regularly missing consultant-led post-take ward rounds (PTWRs). This study aimed to determine the frequency with which the admission diagnosis was changed on the PTWR, and thus whether an educational opportunity for trainees is missed.

METHODS

Prospective observational study of consecutive admissions to a general surgery department over a 4-week period was conducted. Patients with exacerbations of known conditions were excluded.

RESULTS

Fifty-two included patients were admitted by seven general surgery juniors, and 27 per cent (14/52) of diagnoses were changed on the PTWR. There were two 'major' diagnostic changes: peritonitis and ischaemic bowel. Patients whose diagnoses were changed by the consultant were no more likely to be older (p = 0.575) or have differing white cell counts (p = 0.471), C-reactive proteins (CRPs; p = 0.643) or amylase levels (p = 0.666) than those whose initial diagnosis was agreed with. Thirty-five per cent of patients (18/52) had further investigations ordered at the PTWR. These included nine ultrasound scans, four computed tomography scans, three abdominal or chest X-rays, two flexible sigmoidoscopies and one barium enema. In one case, a serum amylase was ordered.

CONCLUSIONS

The rate of incorrect diagnoses by on-call surgical juniors is high, and educational feedback to these doctors is important. The PTWR represents a strong educational opportunity that is missed if admitting junior doctors are not present. These results should be taken into account for any specialty that uses junior doctors to admit patients who are then reviewed by a consultant on a PTWR.

Conceptual frameworks in the study of duty hours changes in graduate medical education: a review

PURPOSE

Conceptual frameworks are approaches to a research problem that specify key entities and their relationships. The 2009 Institute of Medicine (IOM) report on resident duty hours, subsequent studies, and published responses to the report present a variety of conceptual frameworks for the study of the impact of duty hours regulations. The authors sought to identify and describe these conceptual frameworks and their implications.

METHOD

The authors reviewed the IOM report and articles in both peer-reviewed and non-peer-reviewed literature for the period January 2008 through April 2010, identified using multiple electronic databases including PubMed, EMBASE, CINAHL, BEME, and PsycInfo. Studies that explicitly described or argued for the effect of resident duty hours on any other outcome, as judged by consensus of multiple reviewers, were included. The authors selected 239 of 858 studies reviewed. Several of the authors reviewed articles to identify conceptual frameworks used implicitly or explicitly to describe the relationship between duty hours (or duty hours regulations) and outcomes. Identification was by consensus.

RESULTS

Twenty-three conceptual frameworks were identified. Several made contradictory predictions about the impact of duty hours regulations on patient outcomes, resident education, and other key outcomes.

CONCLUSIONS

The concept of duty hours itself is contested, and little attention has been paid to the nature and intensity of the activities that occupy residents' hours. Much research focuses on isolated outcomes of duty hours changes without considering mediation or moderation. More studies are needed to define trade-offs between outcomes and the value society places on these trade-offs.

The relationship between workload and medical staffing levels in a paediatric cardiac intensive care unit

OBJECTIVE

To evaluate the matching between workload in a paediatric cardiac intensive care unit (ICU) and the corresponding medical staffing levels over a 24-h period.

DESIGN

A review of workload measured by: (a) admissions, (b) severity of illness in admissions using case-mix descriptors and mortality as a proxy, (c) cardiac arrests (CA) and (d) extracorporeal membrane oxygenation (ECMO) cannulations. An evaluation of matching between workload and medical staff schedules.

SETTING

A tertiary paediatric cardiac ICU.

PATIENTS

2,799 admissions over a 49-month period.

RESULTS

New admissions peaked in the evening, and the ratio of doctors' hours to admissions was lowest between 1359 and 2000 h. Although only 515 (17.3%) cases were admitted between 2000 and 0759 h, these were more likely to be emergencies, to have higher Paediatric Index of Mortality 2 (PIM2) scores and to die (p < 0.001). There was an increased adjusted risk of death in admissions between 2000 and 0159 h (p = 0.021). There was no difference in the occurrence of either CA (p = 0.41) or ECMO (p = 0.95) between day and night. The ratio of doctors' hours to CAs and ECMOs was lowest from 2000 to 0800 h. The conventional medical staffing roster generated the greatest concentration of staff in the morning, reducing to the lowest level between 0200 and 0759 h.

CONCLUSIONS

Workload was most intense for the in-house team at night, in terms of sicker admissions, ECMOs and cardiac arrests. Conventional roster patterns may not offer ideal matching between staffing and workload. Data analysis of variable and urgent workload may be used to inform medical rosters.

Patient safety and quality of care continue to improve in NHS North West following early implementation of the European Working Time Directive

OBJECTIVES

NHS North West aimed to fully implement the European Working Time Directive (EWTD) 1 year ahead of the August 2009 national deadline. Significant debate has taken place concerning the implications of the EWTD for patient safety. This study aims to directly address this issue by comparing parameters of patient safety in NHS North West to those nationally prior to EWTD implementation, and during 'North West-only' EWTD implementation.

DESIGN

Hospital standardised mortality ratio (HSMR), average length of stay (ALOS) and standardised readmission rate (SRR) in acute trusts across all specialties were calculated retrospectively throughout NHS North West for the three financial years from 2006/2007 to 2008/2009. These figures were compared to national data for the same parameters.

RESULTS

The analysis of HSMR, ALOS and SRR reveal no significant difference in trend across three financial years when NHS North West is compared to England. HSMR and SRR within NHS North West continued to improve at a similar rate to the England average after August 2008. The ALOS analysis shows that NHS North West performed better than the national average for the majority of the study period, with no significant change in this pattern in the period following August 2008. When the HSMRs for NHS North West and England are compared against a fixed benchmark year (2005), the data shows a continuing decrease. The NHS North West figures follow the national trend closely at all times.

CONCLUSION

The data presented in this study quantitatively demonstrates, for the first time, that implementation of the EWTD in NHS North West in August 2008 had no obvious adverse impact on key outcomes associated with patient safety and quality of care. Continued efforts will be required to address the challenge posed nationally by the restricted working hour's schedule.

US public opinion regarding proposed limits on resident physician work hours

BACKGROUND

In both Europe and the US, resident physician work hour reduction has been a source of controversy within academic medicine. In 2008, the Institute of Medicine (IOM) recommended a reduction in resident physician work hours. We sought to assess the American public perspective on this issue.

METHODS

We conducted a national survey of 1,200 representative members of the public via random digit telephone dialing in order to describe US public opinion on resident physician work hour regulation, particularly with reference to the IOM recommendations.

RESULTS

Respondents estimated that resident physicians currently work 12.9-h shifts (95% CI 12.5 to 13.3 h) and 58.3-h work weeks (95% CI 57.3 to 59.3 h). They believed the maximum shift duration should be 10.9 h (95% CI 10.6 to 11.3 h) and the maximum work week should be 50 h (95% CI 49.4 to 50.8 h), with 1% approving of shifts lasting >24 h (95% CI 0.6% to 2%). A total of 81% (95% CI 79% to 84%) believed reducing resident physician work hours would be very or somewhat effective in reducing medical errors, and 68% (95% CI 65% to 71%) favored the IOM proposal that resident physicians not work more than 16 h over an alternative IOM proposal permitting 30-h shifts with > or =5 h protected sleep time. In all, 81% believed patients should be informed if a treating resident physician had been working for >24 h and 80% (95% CI 78% to 83%) would then want a different doctor.

CONCLUSIONS

The American public overwhelmingly favors discontinuation of the 30-h shifts without protected sleep routinely worked by US resident physicians and strongly supports implementation of restrictions on resident physician work hours that are as strict, or stricter, than those proposed by the IOM. Strong support exists to restrict resident physicians' work to 16 or fewer consecutive hours, similar to current limits in New Zealand, the UK and the rest of Europe.

Making sense: duty hours, work flow, and waste in graduate medical education

Parsimony, and not industry, is the immediate cause of the increase of capital. Industry, indeed, provides the subject which parsimony accumulates. But whatever industry might acquire, if parsimony did not save and store up, the capital would never be the greater.Adam Smith, The Wealth of Nations, book 2, chapter 31In 2003, the Accreditation Council for Graduate Medical Education implemented resident duty hour limits that included a weekly limit and limits on continuous hours. Recent recommendations for added reductions in resident duty hours have produced concern about concomitant reductions in future graduates' preparedness for independent practice. The current debate about resident hours largely does not consider whether all hours residents spend in the educational and clinical-care environment contribute meaningfully either to residents' learning or to effective patient care. This may distract the community from waste in the current clinical-education model. We propose that use of "lean production" and quality improvement methods may assist teaching institutions in attaining a deeper understanding of work flow and waste. These methods can be used to assign value to patient- and learner-centered activities and outputs and to optimize the competing and synergistic aspects of all desired outcomes to produce the care the Institute of Medicine recommends: safe, effective, efficient, patient-centered, timely, and equitable. Finally, engagement of senior clinical faculty in determining the culture of the care and education system will contribute to an advanced social-learning and care network.
