Psychometric properties of the Korean version of the Occupational Fatigue Exhaustion Recovery Scale in a nurse population

The measurement of fatigue in clinicians within hospital settings: A systematic review of measurement properties

Medical staff fatigue leads to accidents and mistakes and puts patient safety at risk. A measure of fatigue in the workplace may help to quantify, predict, and manage fatigue. This review aimed to evaluate instruments used to measure fatigue in medical staff within hospitals. A systematic review following the JBI methodology was undertaken. A search for articles was conducted in 2021. Included articles (all validation studies) were assessed for methodological quality using the COSMIN checklist. Measurement property data was evaluated for Quality of Evidence using GRADE methodology. Ten studies representing five instruments were reviewed: Occupational Fatigue Exertion and Recovery scale (now superseded); Occupational Fatigue Exertion and Recovery scale (15-item); Multidimensional Fatigue Inventory; Need for Recovery Scale; and the Swedish Occupational Fatigue Inventory. Four instruments show promise for measuring fatigue in hospital medical staff, however, there is limited certainty in the measure property estimates. The Quality of Evidence for measurement properties for all instruments is insufficient. Further validation studies following the COSMIN standards are needed before recommendations for use can be made.

Factors influencing nurse fatigue during COVID-19: regression vs. fuzzy-set qualitative comparative analysis

Background

Nurses during COVID-19 who face significant stress and high infection risk are prone to fatigue, affecting their health and quality of patient care. A cross- sectional study of 270 nurses who went to epidemic area to support anti-epidemic was carried out via online survey during the COVID-19 pandemic on November 2021.

Methods

A web-based cross-sectional survey of 270 nurses in China who traveled to Heihe City in Heilongjiang Province to combat the novel coronavirus epidemic. The researchers collected information on sociodemographic variables, anxiety, transition shock, professionalism, collaboration, hours of work per day, and fatigue. Regression and fuzzy-set Quality Comparative Analysis (fsQCA) evaluated the factors' impact on the nurses' fatigue.

Results

Regression analysis showed that the psychological variables significant for fatigue, transition shock (β = 0.687, p < 0.001) and anxiety (β = 0.757, p < 0.001) were positively associated with fatigue, professionalism (β = -0.216, p < 0.001) was negatively associated with fatigue, and among the work-related variables, cooperation (β = -0.262, p < 0.001) was negatively related to fatigue. FsQCA analysis showed that combined effects of work hours, anxiety, and nurses' educational status caused most of the fatigue (raw coverage = 0.482, consistency = 0.896).

Conclusion

This study provides two main findings, the one is the greater transition shock experienced during COVID-19 in a new environment, low levels of professionalism, anxiety, and poor nursing teamwork situations lead anti-epidemic nurses to increased fatigue. Second, the fsQCA results showed that anxiety is sufficient for fatigue and that nurses' educational status, daily working hours, and anxiety are the most effective combination of factors.

Overtime and alertness of rotating-shift nurses: An observational study using ecological momentary assessment

AIMS AND OBJECTIVES

This study aimed to determine the effect of overtime on alertness at work among rotating-shift nurses in South Korea and to investigate whether these effects of overtime vary across the different types of shifts.

BACKGROUND

Nurse overtime is prevalent in healthcare settings to manage nursing shortages and staffing needs; however, it negatively affects patient and nurse outcomes. Furthermore, little attention has been paid to the effects of previous overtime shifts and overtime for consecutive shifts on alertness during work.

DESIGN

A prospective observational study was employed. The study followed STROBE checklist for observational studies.

METHODS

Data were collected between June 2019 and February 2020 from 82 nurses who worked in acute care hospitals. An ecological momentary assessment was used to capture real-time data of overtime and alertness. Alertness scores were estimated using the sleep/wake data measured by an actigraph. Mixed-effect models were employed to investigate the association between overtime and alertness.

RESULTS

A majority of the shift nurses worked overtime. Episodes of a decline in alertness scores to the level of increased accident or serious error risk (alertness score ≤80) were most frequently seen during night shifts (98.9%), followed by day (59.8%) and evening shifts (10.1%). Previous-day overtime hours and consecutive overtime days were associated with decreased alertness scores during work. A significantly positive correlation was observed between alertness scores ≤80 and previous-day overtime hours and consecutive overtime days in all shifts.

CONCLUSIONS

The study findings indicate that a majority of nurses who work overtime experience decreased alertness while on duty.

RELEVANCE TO CLINICAL PRACTICE

Policy development at the government, organisational and unit level is needed to guarantee adequate rest for shift nurses by adjusting work schedules and assignments and limiting overtime.

Müdigkeit, Fatigue und Erschöpfung: Alles das Gleiche oder Ausprägungen eines Kontinuums? – Ein Diskussionsanstoß

Bedingt durch die COVID-19-Pandemie und das damit einhergehende Post-COVID-Syndrom, hat der Begriff der „Fatigue“ deutlich an Bedeutung gewonnen. Aber sowohl Definition wie auch Ursachen der Fatigue differieren in Abhängigkeit des jeweils betrachteten Krankheitsbildes. Zudem verwenden Betroffene, die ihre Symptomatik im alltäglichen Klinikalltag beschreiben, scheinbar nahezu durchgehend die Begriffe Müdigkeit, Fatigue und Erschöpfung synonym. Im Jahr 2007 beschrieb Olson, dass aus ihrer Sicht diese drei Begriffe als distinkte Zustände zu verstehen sind, diese aber auf einem Kontinuum in Relation zueinander gesetzt werden können. Diese Überlegung aufgreifend, wird ein Überblick über die aktuelle Forschung gegeben. Hierzu wurde die veröffentlichte Literatur der letzten zwei Jahre nach den Begriffen „Tiredness“, „Fatigue“ und „Exhaustion“ durchsucht. Es lassen sich einige gemeinsame Diagnoseinstrumente finden. Jedoch fällt die große Vielfalt der Instrumente auf, die zur Erfassung der drei Begriffe herangezogen werden. Trotz dieser unterschiedlichen Diagnose- und damit Definitionsmöglichkeiten lassen sich für die drei Symptome jeweils unterschiedliche therapeutische Maßnahmen ableiten. Es ist gerade vor dem Hintergrund der weiteren Therapie entscheidend, die drei Begriffe der Müdigkeit, der Fatigue und der Erschöpfung, voneinander zu trennen und jeweils einzeln auf dem gemeinsamen Kontinuum zu betrachten. Denn nur so ist sowohl eine zutreffende Diagnose als auch eine damit einhergehende erfolgreiche individuelle Therapie ableitbar.

Occupational fatigue, workload and nursing teamwork in hospital nurses

AIMS

To evaluate the relationships between workload, nursing teamwork and nurse fatigue and the moderating effect of nursing teamwork on the relationship between workload and fatigue.

DESIGN

This cross-sectional online survey study used data from 810 United States hospital nurses collected between March and April 2021.

METHODS

Workload, nursing teamwork and fatigue were measured using the Quantitative Workload Inventory, the Nursing Teamwork Survey, and the Occupational Fatigue Exhaustion Recovery scale. Hierarchical multiple linear regression models were used.

RESULTS

All the nursing teamwork subscales (i.e. trust, team orientation, backup, shared mental model, team leadership) were significantly negatively related to acute and chronic fatigue. Nursing teamwork components of team orientation, shared mental model and team leadership moderated the relationship between workload and chronic fatigue. The relationships between workload and chronic fatigue were stronger when these components of nursing teamwork were high. No moderating effects were found with acute fatigue.

CONCLUSION

Efforts to increase nursing teamwork may be a promising strategy in managing nurse fatigue. It is equally important to monitor and modify high workload to protect nurses from elevated fatigue.

IMPACT

WHAT PROBLEM DID THE STUDY ADDRESS?: Fatigue is negatively associated with the health and safety of hospital nurses and patients. Nursing teamwork has been shown to improve the nursing care of hospitalized patients; yet, it is rarely explored in relation to nurse fatigue. WHAT WERE THE MAIN FINDINGS?: Greater nursing teamwork is significantly associated with lower acute and chronic fatigue. The relationships between workload and chronic fatigue were stronger when nursing teamwork (i.e. team orientation, shared mental model and team leadership) was high than when nursing teamwork was low. WHERE AND ON WHOM WILL THE RESEARCH HAVE AN IMPACT?: Improving nursing teamwork, in addition to monitoring and modifying workloads, can be a promising approach for managing fatigue in healthcare organizations.

Work schedule characteristics associated with sleep disturbance among healthcare professionals in Europe and South Korea: a report from two cross-sectional surveys

Background

Healthcare professionals worldwide are prone to sleep disturbance. Such sleep disturbance is associated with lower patient safety and quality of care. Therefore, this study aimed to identify the prevalence of sleep disturbance and determine the effect of work schedule characteristics on sleep disturbance among healthcare professionals in Europe and South Korea.

Methods

We used the sixth European Working Conditions Survey and the fifth Korean Working Conditions Survey for analyses. The study included 2285 healthcare professionals aged 18–65 years. Work schedule characteristics included shift work, night work, working hours per week, long work hours (i.e., more than 10 hours per shift), quick return to work, having to come to work on short notice, and changes in work schedules. A multiple logistic regression analysis was performed.

Results

The overall prevalence of sleep disturbance was 37.7%. The multivariate logistic regression model indicated that long work hours, quick return to, having to come to work on short notice, and changes in work schedules were significant factors associated with sleep disturbance among healthcare professionals.

Conclusion

The findings revealed that several work schedule-related factors were associated with sleep disturbances in healthcare professionals in Europe and Korea. Institutions and policymakers should implement strategies and policies to reduce the unpredictability of work schedules to ensure an adequate rest period between shifts and to reduce sleep disturbances.

Psychometric properties of the Japanese version of the Occupational Fatigue Exhaustion Recovery Scale among shift-work nurses

Objectives

Shift‐work nurses are at a higher risk of inadequate recovery from fatigue and developing maladaptive fatigue with significant health consequences. Therefore, it is necessary to monitor fatigue and recovery levels with a reliable scale. We investigated psychometric properties of the Japanese version of the Occupational Fatigue Exhaustion Recovery scale (OFER‐J) for shift‐work nurses.

Methods

Japanese shift‐work nurses responded to self‐administered questionnaires at baseline (n = 942) and one month later (n = 334). The confirmatory factor analysis (CFA) and exploratory factor analysis (EFA) were conducted to verify the structural validity and the correlation analysis and one‐way analysis of variance were conducted to test the construct and discriminative validity. Cronbach's alpha coefficient, intra‐class correlation coefficient (ICC), and smallest detectable change (SDC) were calculated to assess reliability.

Results

The CFA showed high correlations between the factors and whilst the goodness‐of‐fit of the three‐factor model was suboptimal, it was in an acceptable range. Most modifications included the error covariance of the Acute Fatigue (AF) and Intershift Recovery (IR) items. The EFA showed that Chronic Fatigue (CF) and AF were not clearly separated, indicating that the two AF items dropped out. Construct and discriminative validity were also well indicated. Cronbach's alpha coefficients were 0.75–0.85. Only CF showed sufficient reproductivity (ICC = 0.74). The SDC for CF, AF, and IR was 14.0, 17.1, and 18.7, respectively.

Conclusions

The validity and reliability of the OFER‐J were verified as acceptable for shift‐work nurses. The OFER‐J could contribute to a data‐based approach to fatigue management in nursing management practice.

Psychometric evaluation of the perceived perioperative competence scale-revised among the Chinese operating room nurses: a methodological research

Background

Perioperative competence is necessary to evaluate operating room nurses. The Perceived Perioperative Competence Scale-Revised (PPCS-R) is the only available tool developed specifically for the perioperative setting. However, there is a lack of research on the reliability and validity of this scale among Chinese nurses. Thus, the aim of this study is to translate, culturally adapt, and evaluate the psychometric properties of the Perioperative competence Scale-Revised (PPCS-R) among operating room nurses in China.

Methods

Instrument cultural adaptation was carried out through forward translation, back translation, expert panel evaluation and pretesting. The psychometric properties (content validation, item analysis, construct validation, and reliability coefficient) of the Chinese PPCS-R (C-PPCS-R) were examined. An online survey was completed from June to August 2020 by operating room nurses (N = 480) in five third-grade class-A hospitals in Beijing.

Results

The item analysis identified six items for scale reduction. Exploratory factor analysis showed the remaining 34 items loaded on six factors, which were named in accordance with the original scale. The six-factor model showed a good fit through confirmatory factor analysis. The item content validity index for the C-PPCS-R items ranged from 0.857 to 1.000, and that for the total scale was 0.875. Cronbach’s alpha was showed 0.787. Together, the six factors explained 68.62% of the variance.

Conclusions

The 34-item C-PPCS-R showed good validity and reliability to measure perceived competence among operating room nurses in the Chinese context. The scale can assist nurse managers to identify operating room nurses’ perceived competence, and provides evaluation criteria for career planning, performance appraisal, job assignment, and continuing education.

Alertness during working hours among eight-hour rotating-shift nurses: An observational study

PURPOSE

The aim of this study was to identify the patterns of the decline in the alertness of rotating-shift nurses during working hours across different shift types (day, evening, and night) using an objective measure.

DESIGN

An observational study using ReadiBand wrist actigraphs was conducted.

METHODS

Data were collected from June 2019 to February 2020. Participants were rotating-shift nurses (N = 82) who provided direct nursing care for patients in acute care hospitals in South Korea. Nurses wore actigraphs continuously for 14 days on their non-dominant hand to identify sleep-wake cycles and predict their alertness scores hourly. All participants completed a sleep diary.

FINDINGS

Nurses working during night shifts had lower average alertness scores (mean = 77.12) than nurses working during day (mean = 79.05) and evening (mean = 91.21). Overall, alertness showed a declining trend and the specific patterns of decline differed across shifts. Participants with alertness scores less than 70 or 80 demonstrated a significant decline in alertness across all shifts.

CONCLUSIONS

Distinct patterns of decline in alertness per nursing shift were revealed. Each shift feature should be considered when developing interventions to increase nurses' alertness, promote high-quality care provision, and ensure patient safety.

CLINICAL RELEVANCE

The implementation of interventions to increase alertness among shift nurses is needed at the organizational level, and the cooperation of nursing managers and administrators is required.

Work schedule characteristics and occupational fatigue/recovery among rotating-shift nurses: A cross-sectional study

AIMS

To determine the effects of work schedule characteristics on occupational fatigue and recovery among rotating-shift nurses in South Korea.

BACKGROUND

Understanding the effects of work schedule characteristics on occupational fatigue is important to prevent adverse nurse outcomes and to ensure patient safety.

METHODS

This study used secondary data analysis with a cross-sectional design. Data were collected on 436 rotating-shift nurses in 2018. Nurses' occupational fatigue and recovery were measured using the Occupational Fatigue Exhaustion/Recovery Scale. We used quantile regression models.

RESULTS

The scores for acute and chronic fatigue and intershift recovery were 70.40, 73.39, and 29.82, respectively. Overtime hours, number of night shifts, number of consecutive days off, and breaks were significant influential factors in some quantiles of acute fatigue, chronic fatigue, and intershift recovery, while total working hours was only associated with chronic fatigue in the 25th quantile.

CONCLUSIONS

The quantile and linear regression models revealed different results for work schedule factors that affect occupational fatigue and intershift recovery among rotating-shift nurses.

IMPLICATION FOR NURSING MANAGEMENT

These findings have important implications for developing targeted strategies and policies to reduce occupational fatigue and improve intershift recovery for rotating-shift nurses with different levels of occupational fatigue and recovery.

Psychometric properties of the Portuguese version of the occupational fatigue exhaustion/recovery (OFER) scale among industrial shift workers

Reliable and valid instruments are essential for understanding fatigue in occupational settings. This study analyzed the psychometric properties of the Portuguese version of the Occupational Fatigue Exhaustion/Recovery (OFER). A cross-sectional study was conducted with 260 workers (M = 46.52 ± 13.16 years) from a textile industry, exposed to shift work. Convergent and discriminant validity, internal consistency reliability and exploratory and confirmatory factor analysis were performed. Results showed an adequate fit to data (χ² (84) = 209,102, CFI = 0.936, GFI = 0.902, RMSEA = 0.076 CI90% (0.063-0.089)), yielding a 13-item, three factor structure. Two items were removed due to low factor loading. The OFER presented an adequate internal consistency, with the subscales presenting good reliability values (Chronic Fatigue (α = 0.81), Acute Fatigue (α = 0.84) and Recovery between Shifts (α = 0.77)). Findings suggest that the Portuguese version of OFER can be a useful tool to assess occupational fatigue of shift workers and prevent work related injuries.

Sleep, fatigue and alertness during working hours among rotating-shift nurses in Korea: An observational study

AIMS

To determine the effects of sleep parameters and fatigue on the decline in alertness of nurses across shifts.

BACKGROUND

Shift work can lead to nurse fatigue owing to insufficient sleep and inadequate recovery time between shifts. Nurse fatigue has adverse effects on alertness and can affect provision of quality care.

METHODS

An observational study using wrist actigraphs was conducted from 2019 to 2020. Participants were 82 rotating-shift nurses who provided direct nursing care in acute hospitals in South Korea. They wore actigraphs for 14 days to measure sleep parameters and predict hourly alertness and reported subjective fatigue before and after every shift.

RESULTS

Nurses demonstrated shorter sleep hours, lower sleep efficiency and longer sleep latency before night shifts compared with other shifts. Fatigue was the highest before day shifts. Sleep parameters and fatigue significantly affected the steep decline in alertness in participants with alertness scores below 70.

CONCLUSIONS

Sleep parameters and fatigue level contributed to the differences in decline in alertness across shifts.

IMPLICATION FOR NURSING MANAGEMENT

Findings inform nurse managers, administrators to develop interventions to reduce fatigue, improve sleep quantity and quality and increase alertness among rotating-shift nurses. Management, institutional and individual factors should be considered when developing interventions.

Acute and chronic fatigue in nurses providing direct patient care and in non-direct care roles: A cross-sectional analysis

Nurses are at risk for work-related fatigue, which can impact their health, well-being, and job readiness. The purpose of this study was to examine the levels, types, and factors associated with fatigue in registered nurses (RNs) in direct patient care (DCRNs) and in non-direct patient care (non-DCRNs) roles. A cross-sectional survey was administered to 313 RNs. Measures included: Multidimensional Fatigue Symptom Inventory, Occupational Fatigue Exhaustion Recovery, Brief COPE, PROMIS® Global Sleep Disturbance, and Job Content Questionnaire. Acute fatigue levels in RNs were similar to those in diseased populations, and nearly 50% reported moderate/high levels of chronic fatigue. DCRNs reported higher levels of acute and chronic fatigue than non-DCRNs, but the differences were small and disappeared when accounting for other factors associated with fatigue including sleep disturbance, job strain, workplace support, maladaptive coping, and especially intershift recovery, which accounted for 20%-41% of fatigue variability. This study suggests that it may not be only nurses providing direct patient care who are at risk for acute and chronic fatigue. Intershift recovery may be particularly important in alleviating acute and chronic fatigue in nurses.

Hearing the Voices of Wingless Angels: A Critical Content Analysis of Nurses' COVID-19 Experiences

The world has been affected by an outbreak of the novel coronavirus (COVID-19). Health care workers are among those most at risk of contracting the virus. In the fight against the coronavirus, nurses play a critical role. Still, most social media platforms demonstrate that nurses fear that their health is not being prioritized. The purpose of this study is to investigate nurses' experiences through analyzing the main themes shared on Instagram by nurses during the COVID-19 pandemic. In contrast with highly structured research, the current paper highlights nurses' natural language use in describing their experiences during the first months of the outbreak in their workplace. Instagram captions were utilized as a data source. Leximancer was utilized for the content analysis of nurses' narratives towards their coronavirus experience. We sought to accomplish three research objectives: the first was to identify the main themes in the descriptions of nurses' experiences shared via their social media, specifically Instagram; then, to determine the relationships among concepts, and finally, to give useful implications based on the findings. The current study uses a qualitative (i.e., narratives) approach to analyze the main components of the nurses' experiences during the pandemic. The Leximancer software analysis revealed nine major textual themes and the relationships among these themes. In order of the relative importance, the themes were "patients", "coronavirus", "exhaustion", "family", "hospital", "personal protective equipment" (PPE), "shift", "fear", and "uncertainty". The results offer practical implications based on the social media information regarding nurses' overall experiences.
