Fatigue and the Female Nurse: A Narrative Review of the Current State of Research and Future Directions

Effects of job demands, job resources, personal resources on night-shift alertness of ICU shift nurses: a cross‑sectional survey study based on the job demands-resources model

BACKGROUND

A positive work environment can enhance nursing safety and patient satisfaction while alleviating nurse stress. Conversely, a poor work environment can harm nurses' physical and mental health and compromise the quality of care, particularly in the high-intensity and shift-based setting of the ICU.

OBJECTIVES

Based on the Job demands-resources (JD-R) model, this study examined the effects of job demands and job resources in the work environment, as well as personal resources, on the night-shift alertness of ICU shift nurses.

METHODS

This cross-sectional correlational exploratory study, conducted from July to September 2022, recruited 291 ICU shift nurses from a hospital in Beijing, China. The Copenhagen Psychosocial Questionnaire (COPSOQ), the Self-resilience scale, the General Self-Efficacy Scale (GSES), and the Psychomotor Vigilance Task (PVT) were used to subjectively and objectively measure the job demands, job resources, personal resources, and night-shift alertness. SPSS 26.0 and Mplus 8.3 were used to analyze the data and construct the structural equation model.

RESULTS

The night-shift reaction time was 251.0 ms (Median), indicating a relatively high level of alertness. Job demands were negatively correlated with both job resources (r=-0.570, P < 0.001) and personal resources (r=-0.462, P < 0.001), while a positive correlation existed between job resources and personal resources (r = 0.554, P < 0.001). The results show that increased job demands can lead to higher levels of nurse strain (β = 0.955, P < 0.001), whereas job resources were found that it can decrease strain (β=-0.477, P = 0.047). Adequate job resources can enhance motivation directly (β = 0.874, P < 0.001), subsequently reducing reaction time (β=-0.148, P = 0.044) and improving night-shift alertness among ICU shift nurses.

CONCLUSION

Enhancing ICU shift nurses' work motivation through bolstering job resources can boost night-shift alertness. However, it is noteworthy that, in this study, neither strain nor individual resources significantly influenced nurses' night-shift alertness. This may be attributed to the complexity of the ICU environment and individual differences. Future research should explore the relationship between these factors and nurses' work alertness.

Survey of role stress among specialty nurses working in tertiary general hospitals across China: a cross-sectional descriptive study

BACKGROUND

Occupational stress can affect specialty nurses' quality of work, especially for those working in care units. This study, therefore, investigated role stress and its related factors among specialty nurses working in tertiary general hospitals.

METHODS

This cross-sectional descriptive study used convenience sampling to recruit 795 Chinese specialty nurses in 11 tertiary general hospitals (from February to March 2023). A questionnaire survey was conducted using the Basic Information Questionnaire and the Role Stress Scale. Multiple linear regression analyses were performed on the survey data to explore the factors affecting role stress.

RESULTS

The total role stress score of specialty nurses in tertiary general hospitals was 52.05 ± 19.98. The highest mean item score was quantitative overload, followed by qualitative overload, role conflict, and role ambiguity, which had the lowest score. Multiple linear regression analysis revealed that gender (β = -0.085, p < 0.05), educational background (β = 0.077, p < 0.05), and work experience (β = -0.104, p < 0.05) were the main factors influencing role stress among specialty nurses.

CONCLUSIONS

Specialty nurses in tertiary general hospitals had higher levels of role stress than general nurses. Their role stress was primarily reflected in role overload, followed by role conflict and ambiguity. The factors affecting specialty nurses' role stress included gender, work experience, and educational background. Nursing managers should monitor the role stress experienced by specialty nurses in tertiary general hospitals. Providing psychological support for male specialty nurses, performance rewards and learning opportunities for highly educated specialty nurses, and continuous training for inexperienced specialty nurses are essential measures to relieve role stress.

The relationship between mental fatigue and social responsibility among nurses who provided care to patients with coronavirus disease 2019: a cross-sectional study

BACKGROUND AND AIM

Mental fatigue (MF) was a major challenge for nurses during the coronavirus disease 2019 (COVID-19) pandemic. Nurses' sense of responsibility towards their patients and societies may influence their MF. This study aimed to assess the relationship between MF and social responsibility (SR) among nurses who provided care to patients with COVID-19.

METHODS

This cross-sectional descriptive-analytical study was conducted in 2021. Participants were 258 nurses randomly selected from eleven COVID-19 care hospitals in Tehran, Iran. Data were collected using three self-report instruments, namely a demographic questionnaire, the Mental Fatigue Scale, and the Social Responsibility Questionnaire. The SPSS software (v. 16.0) was used to analyze the data at a significance level of less than 0.05.

RESULTS

The mean scores of MF and SR were 31.73 ± 7.35 and 3.45 ± 0.35, respectively. The highest and the lowest scored SR subscales were ethical responsibilities with a mean of 3.67 ± 0.42 and economic responsibilities with a mean of 2.93 ± 0.62. MF had a significant negative correlation with legal responsibilities and a significant positive correlation with economic responsibilities (P < 0.05). The only significant predictor of SR was financial status which significantly predicted 4.3% of the variance of SR (P < 0.05).

CONCLUSION

More than half of the nurses who provided care to patients with COVID-19 suffered from MF and their mental fatigue had a significant correlation with their legal and economic responsibilities. Healthcare authorities and policymakers need to develop programs to reduce nurses' MF and improve their satisfaction.

Well-Being, Occupational Fatigue, and Sleep Quality among Filipino Nurses working during COVID-19

Fatigue is a common symptom experienced by nurses before the pandemic, but this experience is heightened by the coronavirus (COVID-19) pandemic. The literature has ample evidence of nurses experiencing occupational or work-related fatigue. In addition, human error is a significant consequence of fatigue that can significantly impact patient outcomes and be devastating for a nurse. Guided by Lazarus and Folkman's Transactional Theory of Stress and Coping, we conducted a descriptive, correlational and cross-sectional study aimed to 1) explore the level of occupational fatigue and sleep quality among Filipino nurses working during the COVID-19; 2) determine the relationships between occupational fatigue, sleep quality, and subjective wellbeing among Filipino nurses working during COVID-19 pandemic. One hundred twenty-six Filipino nurses across the United States working during the pandemic were surveyed using RedCap. The study showed that Filipino nurses had moderate to high acute and chronic fatigue levels, lower intershift recovery, and good sleep quality. Evidence and opportunities for health care administrations to create strategies to enhance the wellbeing of their largest and most valuable workforce.

Preserving the Bedside Nurse: Grip Strength and Orthopedic Problems Among Nurses and Nursing Students

Background:

Bedside nurses and nursing students are at increased risk of musculoskeletal injury due to the physicality and complexity of their work. The purpose of this study was to explore the relationship between grip strength and orthopedic injuries or pain among nurses and nursing students.

Methods:

A cross-sectional study of nursing staff and nursing students at a health sciences university was conducted. The survey consisted of work-related demographics, exercise habits, and validated scales. The Nordic Musculoskeletal Questionnaire was used to collect information on musculoskeletal problems. Anthropomorphic measures included height, weight, body mass index (BMI), and grip strength. Logistic regression was performed.

Findings:

Participants with grip strength at or above the national average had significantly lower odds of self-reported orthopedic problems, B = 0.86, OR = 2.35, p =.01, indicating participants with grip strength at or above national average were 135% less likely to report orthopedic problems compared to participants with grip strength below the national average.

Conclusion/Application to Practice:

Healthcare workers in direct patient care who have lower grip strength may be at increased risk for injuries. Nursing staff and students with below average grip strength were more likely to experience orthopedic problems. Increased muscle mass and grip strength are known to effectively reduce the risk of upper extremity injuries. Nurse leaders may benefit from promoting grip strengthening activities among employees to prevent workplace injuries. Further research is needed to understand the biophysiological mechanisms, confirm the findings of this study and evaluate effective interventions.

Self-reported work-related accumulative fatigue of nurses: A cross-sectional study in public hospitals in China

Objectives

Work-related fatigue is a serious safety risk to nurses and their patients. This study aimed to assess self-reported work-related accumulative fatigue of nurses and its associated factors.

Methods

A questionnaire survey of 2,918 clinical nurses conveniently sampled from 48 public hospitals across six provinces in China was conducted. The "Self-diagnosis Checklist for Assessment of Workers' Accumulated Fatigue" was adopted to assess the level of work-related accumulative fatigue of the study participants. Chi-square tests and ordinal regression analyses were performed to determine the sociodemographic characteristics associated with work-related accumulative fatigue.

Results

About one third of respondents reported low work-related accumulative fatigue, compared with 23.1% reporting high and 24.6% reporting very high levels of work-related accumulative fatigue. Higher levels of work-related accumulative fatigue were associated with female gender (AOR = 0.614 for male relative to female, p = 0.005), age between 30 and 40 years (AOR = 1.346 relative to >40 years, p = 0.034), 5-10 years of work experience (AOR = 1.277 relative to >10 years, p = 0.034), and bachelor or above degree qualifications (AOR = 0.806 for associate degree relative to bachelor or above degree, p = 0.007). Those who worked in rural county hospitals (AOR = 0.816 for metropolitan relative to rural county hospitals, p = 0.006) and resided in central China (AOR = 1.276 relative to western China, p = 0.004) had higher odds of reporting higher levels of work-related accumulative fatigue.

Conclusion

High levels of work-related accumulative fatigue are evident in nurses of public hospitals in China. The problem is more serious in the female nurses in their mid-career and those who worked in the central region and rural setting.

Effectiveness of a Mobile Wellness Program for Nurses with Rotating Shifts during COVID-19 Pandemic: A Pilot Cluster-Randomized Trial

Nurses with rotating shifts, including night shifts, have suffered from low physical activity during the COVID-19 pandemic and lower sleep quality due to the disruption of their circadian rhythm. This study aimed to develop and examine the effectiveness of a mobile wellness program on daily steps, sleep quality, exercise self-efficacy, intrinsic motivation for exercise, self-rated fatigue, and wellness. A cluster randomized controlled trial design was used to examine the effectiveness of the mobile wellness program for nurses with rotating shifts. Sixty nurses from one university hospital participated and were allocated to an intervention group and a control group. The intervention group received a 12-week mobile wellness program to improve their physical activity and sleep quality, and the control group was only given a Fitbit to self-monitor their health behaviors. There were significant differences between the two groups in daily steps (p = 0.000), three components (subjective sleep quality, sleep disturbance, daytime dysfunction) of the PSQI, exercise self-efficacy, intrinsic motivation for exercise, and wellness. In conclusion, this study provides meaningful information that the mobile wellness program using Fitbit, online exercise using Zoom, online health coaching on a Korean mobile platform, and motivational text messages effectively promoted physical activity and sleep quality for nurses with rotating shifts during the COVID-19 pandemic.

Test-retest reliability of the 5-minute psychomotor vigilance task in working-aged females

BACKGROUND

The psychomotor vigilance task (PVT) is a commonly used test that effectively assesses neurobehavioral alertness. The originally developed PVT is 10 minutes in duration, which presents practical and logistical issues, particularly when administered to large samples or on a repetitive basis. More recently the PVT has been used in both 3- and 5-minute formats. While both of these durations have been shown to be field sensitive to identify impairments from sleep- and fatigue-related interventions, the 5-minute version has been suggested to be more valid than the 3-minute. However, while these have shown field-validity in a number of working populations, there is a paucity of data reporting the test-retest reliability statistics of the 5-minute PVT, particularly in working-aged females. The purpose of the study was to examine the test-retest reliability of a comprehensive set of PVT variables for the 5-minute PVT in a population of working-aged females (20-63 years).

NEW METHOD

Participants reported to the laboratory on two separate days and performed a 5-minute PVT on each occasion. Outcome measures included the mean reaction time (MRT), fastest and slowest 10% of reaction times (F10RT% and S10RT%, respectively), standard deviation of reaction times (SDRT) as well as error-based metrics including major and minor lapses, anticipations, and false starts. In addition, total errors (ERR) were computed as a composite of all types of errors. Reliability statistics were reported as intraclass correlation coefficients (ICCs), standard error of measurement (SEM, SEM%), and minimal difference to be considered real (MD, MD%). Systematic error was also evaluated between sessions.

RESULTS

Overall high reliability was shown for the MRT (ICC = 0.79, SEM% = 4.14%) and F10RT% (ICC = 0.83, SEM% = 4.43%) variables, with moderate relative reliability (based on ICCs) for the false starts, ERR, and sleepiness scale (ICC = 0.50 - 0.70) variables but these all exhibited poor absolute reliability (based on SEM% values of 32.60 - 168.69%). Poor relative reliability was found for the SDRT and S10RT% variables (ICCs < 0.50) but the S10RT% variable had good absolute reliability (SEM% = 7.12%). The minor and major lapses and anticipations variables had too few of event occurrences for a confident determination of the reliability.

CONCLUSIONS

The finding that the MRT variable displayed systematic error (P = 0.01) indicating that a learning curve may have been present, but the F10RT% did not show systematic error, suggests the F10RT% may be the most reliable PVT variable in a 5-minute duration test. These findings provide researchers and practitioners with reliability statistics that may help in determining which variable(s) to use, and which to avoid when specifically conducting 5-minute PVT assessments, particularly in a population of working-aged females. These results suggest that the 5-minute PVT can be used in place of the 10-minute version, if used appropriately.

Work-related musculoskeletal symptoms among Iranian nurses and their relationship with fatigue: a cross-sectional study

Background

The present study aimed to determine the prevalence of work-related musculoskeletal symptoms (WMSs), identify potential factors associated with WMSs, and determine the association between WMSs and fatigue among nurses.

Methods

This cross-sectional study was carried out among 500 Iranian nurses. Data was gathered by the 1) Persian version of the Nordic musculoskeletal questionnaire (P-NMQ) to examine WMSs, and 2) Persian version of the Multidimensional Assessment of Fatigue (P-MAF) Scale to evaluate fatigue among the study population. Then, data was analyzed by SPSS version 21 using the χ2 test, multiple logistic regression for detection of potential factors associated with WMSs, and multiple linear regression for detection of potential factors associated with fatigue.

Results

Ankles/feet, lower back, knees, and shoulders had the highest prevalence of WMSs among nurses within the last 12 months prior to the study. Independent variables including age, job tenure, gender, smoking, shift work, and type of employment were significantly associated with WMSs in different body regions with odds ratios (ORs) ranging from 1.635–2.835. Moreover, WMSs in some body regions were associated with subscales of fatigue and total fatigue.

Conclusions

Ergonomic and organizational interventions for fitting the job to the nurses considering demographic/occupational characteristics are highly essential to improve musculoskeletal system health and relieve fatigue.
