Work intensification and occupational fatigue on nurses: a cross-sectional and correlational study

PurposeThis research aimed to determine the relationship between work intensification and occupational fatigue in nurses using a cross-sectional and correlational design.MethodsThe sample included 597 nurses from public, private, and university hospitals in Istanbul, selected through convenience sampling. Data were collected using the "Nurse Information Form," the "Intensification of Job Demands Scale," and the "Occupational Fatigue Exhaustion/Recovery Scale." Analysis involved descriptive tests, correlation, and hierarchical linear regression.ResultsResults showed higher-than-average levels of both chronic and acute fatigue, with acute fatigue being more prevalent. The mean intershift recovery score was below average. A significant positive correlation was found between chronic and acute fatigue, while a significant negative correlation was observed between both fatigue types and intershift recovery. Work intensification levels were above average and correlated positively with chronic and acute fatigue, except for intensified career-related planning. Conversely, a negative correlation was found with recovery, except for intensified skill-related learning demands. Regression analysis revealed that demographic and occupational characteristics of nurses other than age, work intensification, acute fatigue, and intershift recovery explained 59.8% of chronic fatigue. For acute fatigue, these factors explained 11.2%, and for intershift recovery, 12.8%.ConclusionsThis study highlights the correlation between work intensification and occupational fatigue in nurses, suggesting that increased work intensity leads to higher occupational fatigue. The findings contribute to the literature and assist nurse managers and decision-makers in preventing occupational fatigue by re-evaluating and regulating current working conditions where job demands are intensified.

Effects of Korean Herbal Medicine on the Recovery of Exercise-Induced Fatigue and Exercise Performance: Narrative Review of animal experiments in Korea

Objectives: Many athletes utilize herbal medicines to enhance their performance. However, studies comprehensively analyzing the impact of Korean herbal medicine (KHM) on exercise performance enhancement are lacking. This study aimed to explore the basis of animal experimental studies on KHM in improving athletic ability and anti-fatigue effects and derive an evidence-based relationship between exercise and KHM intake.Methods: We conducted a systematic search of articles within the Oriental Medicine Advanced Searching Integrated System (OASIS) database. Animal-controlled experimental studies exploring exercise performance and fatigue recovery effects after administering KHM were selected and analyzed. Data were categorized based on exercise methods and outcomes, examining the effects of different KHM.Results: Through experimental research analysis, the effect of KHM on exercise was focused on muscle strength, cardiopulmonary endurance, and anti-fatigue, among basic components of exercise ability. For example, when administering Allii tuberosi semen and Ginseng Radix to an animal model, remarkable muscle strength enhancements were observed. Administration of Allii tuberosi semen, Ginseng Radix, Cervi Parvum Cornu, Ssanghwa-tang, Kyeongok-go, Yukmijihwang-tang, Jakyak-gamcho-tang, and Sogunjung-tang resulted in cardiovascular endurance improvements. Furthermore, Cervi Parvum Cornu, Ganoderma, Ssanghwa-tang, Dangguibohyul-tang, Ssangbohwan, Bojungikgi-tang, Bojungikgi-tang, Jakyak Gamcho-tang, and Sogunjung-tang were effective for fatigue recovery after exercise. We examined the impact of KHM on muscle strength, cardiovascular endurance, and fatigue recovery during exercise.Conclusions: This systematic review of animal-controlled experimental studies establishes a robust evidence-based relationship between KHM consumption and enhanced athletic abilities, offering valuable insights for athletes exploring natural strategies for performance enhancement.

The effects of inorganic nitrate supplementation on muscular power and endurance across the menstrual cycle.

Oral inorganic nitrate ([Formula: see text]) supplementation increases nitric oxide (NO) bioavailability and may improve muscular power in males and females, although data in females are limited. Estrogen increases NO bioavailability and fluctuates throughout the menstrual cycle, with low levels in the early follicular (EF) phase and peaking during the late follicular (LF) phase. The purpose of the present study was to examine the effects of [Formula: see text] supplementation on isokinetic peak power, maximal voluntary isometric contraction (MVIC) force, muscular endurance, and recovery from fatigue in healthy young females during the EF and LF phases of the menstrual cycle. Ten eumenorrheic females were tested in a double-blinded, randomized, placebo-controlled design. Participants consumed ∼13 mmol [Formula: see text], in the form of 140 mL beetroot juice (BRJ), or an identical [Formula: see text]-depleted placebo (PL), for ∼5 days prior to visits and 2 h prior to testing. Plasma estradiol was elevated in the LF phase, and plasma nitrite and nitrate were elevated in the BRJ condition (P < 0.05). Although isokinetic peak power was unchanged, calculated maximal power (Pmax) and maximal velocity (Vmax) were significantly worsened in the BRJ treatment independent of the menstrual cycle phase (P = 0.02 and 0.03, respectively). Muscular endurance, MVIC, and fatigue recovery were unaltered by BRJ or the menstrual cycle. These data indicate that [Formula: see text] supplementation decreased maximal power and velocity in females and suggest that the benefits of [Formula: see text] supplementation previously found in males may not extend to young females.NEW & NOTEWORTHY Recent data have suggested that inorganic nitrate ([Formula: see text]) supplementation may benefit males, however, females may experience worsened endurance capacity independent of menstrual cycle phase. This study revealed neither [Formula: see text] supplementation nor the follicular phase of the menstrual cycle influenced maximal isometric voluntary contraction or endurance capacity in healthy, young, naturally menstruating females, whereas [Formula: see text] supplementation significantly worsened estimated peak power (Pmax) and velocity (Vmax) independent of the menstrual cycle phase.

Effect of repeated hot and cold stimulation for the neck and shoulders on muscle fatigue recovery: a pilot study.

Increased use of electronic devices such as smartphones has led to an increase in neck and shoulder stiffness to the forefront of the public people. It is said that prolonged posture with the head tilted forward causes excessive muscle activity in the head and neck region, resulting in muscle fatigue symptoms such as stiff shoulders. Various bathing methods have been proposed as a means of recovering from muscle stiffness, and in particular, contrast water therapy (CWT) is said to be highly effective in recovering from muscle fatigue. In the present study, we examined the effect of CWT with hot and cold stimulation of the neck and shoulders (CWTNS) on muscle fatigue recovery. As the result, in the CWTNS condition, the effects of vasodilation and vasoconstriction were observed, and muscle hardness was significantly lower than that in the Control condition in 20 subjects (2 males, 18 females). Stress hormones were also decreased during and after bathing compared to those before bathing. These results motivate further exploration of the possibility that the effects of CWTNS could be muscle-recovery without high stress load.

Work-related Fatigue: Relationship between Perceived and Performance Fatigability in Career Firefighters.

The purpose of this study was to 1) examine the relationship between perceived work-related fatigue and performance fatigability, and 2) assess the impact of percent body fat (%BF) on perceived fatigue constructs in career firefighters. Thirty-nine career firefighters completed body composition testing, the Occupational Fatigue Exhaustion Recovery (OFER15) scale assessing three subscales of work-related fatigue (acute fatigue, chronic fatigue, and inter-shift recovery), and maximal leg extensor isometric strength testing prior to and following an isotonic fatiguing protocol. Performance fatigability was not associated with any of the OFER15 perceived work-related fatigue variables ( P ≥ 0.513). Greater %BF was associated with greater %∆ peak torque ( r = -0.41, P = 0.010) but none of the OFER15 perceived work-related fatigue variables ( P ≥ 0.638). Performance fatigability was not associated with OFER15 perceived work-related fatigue, and greater adiposity negatively impacted performance fatigability but not perceived fatigability.

Cryotherapy with carbon dioxide hydrate enhances immediate recovery of muscle function from neuromuscular fatigue

ABSTRACT This study investigated the effect of cryotherapy with carbon dioxide hydrate (CDH) on fatigue recovery of neuromuscular function and muscle blood circulation. Fourteen young males randomly received three types of 20-min recovery interventions (cryotherapy with CDH [CDH-condition] or normal ice [ICE-condition], or quiet sitting at room temperature [CON-condition]) 5 min following a fatiguing task (50 maximal effort isotonic contractions) on three separate days. The isotonic peak power of the knee extensors at 35 min after the fatiguing task in the CDH-condition (95% of baseline) was greater than that in the other conditions (82–89% of baseline; p ≤ 0.031). In addition, at 25 and 35 min after the fatiguing task, the changes in haemoglobin concentration of the knee extensors from before the fatiguing task in the CON-condition (2.5 and 3.0 μmol/L) were different from those in the ICE-condition (−1.4 and −1.3 μmol/L; p ≤ 0.004) but comparable to those in the CDH-condition (1.1 and 0.7 μmol/L; p ≥ 0.060), respectively. These findings suggest that cryotherapy with CDH did not lower the blood volume following the intervention, unlike that with normal ice, and promoted greater immediate recovery of muscle power from neuromuscular fatigue compared with cryotherapy with ice or passive rest.

The Impact of Yoga on Post-Exercise Fatigue among College Students

This study aims to evaluate the effects of yoga on subjective fatigue and heart rate recovery in college students following high-intensity exercise. By comparing groups of students practicing yoga and those resting statically, the study will explore whether yoga is a viable recovery method for reducing fatigue and accelerating heart rate recovery. The results will provide scientific evidence for designing university sports curricula and offer references for managing students' exercise health.

Foam Rolling Intervention Improves Lactate Clearance After High-Intensity Exercise.

The acute effects of a foam rolling intervention on lactate clearance and the impaired executive function associated with fatigue after high-intensity exercise remain unclear. This study examined whether foam rolling is an effective tool for fatigue recovery. Eighteen healthy adults without consistent exercise habits participated in this study. Participants performed high-intensity exercises, and the post-exercise foam rolling intervention was compared to the control condition. Measurements included lactate, vigor/fatigue by the Profile of Mood States 2nd Edition, cognitive function (cognitive task performance), leg and body rating of perceived exertion pre- and post-exercise, and post-intervention. Blood lactate concentrations post-foam rolling intervention (-7.3 ± 3.0 mmol/L) were significantly reduced among all participants. Increased lactate clearance by foam rolling correlated with a faster recovery of executive function for those with greater lactate clearance. However, cognitive fatigue was not observed after high-intensity exercise (p = 0.086, r = 0.41). Lactate clearance was not significantly correlated with the rating of perceived exertion in the foam rolling condition. The rating of the perceived exertion decreased with increased lactate clearance for those with greater lactate clearance in the control condition (leg: r = 0.778; body: r = 0.669). In conclusion, foam rolling intervention may be effective for exhausting exercise recovery.

Viable strategies for enhancing performance in ball sports by mitigating mental fatigue: A systematic review.

Ball sports demand precise control of body and ball while executing tactics and team coordination, which leads to cognitive depletion and mental fatigue. The detrimental effects of mental fatigue on physical, technical, cognitive, and tactical performance in ball sports are evident, highlighting the need for effective management of mental fatigue as a crucial component of modern sports science. This review aims to systematically study and integrate existing experiments on mental fatigue recovery interventions to identify viable strategies for mitigating its impacts. Following PRISMA guidelines, electronic databases including Web of Science, PubMed, SPORTDiscus, and Scopus were used for literature screening. Studies that induced mental fatigue followed by interventions aimed at mental fatigue recovery were included in this review, resulting in 6 articles primarily focused on basketball, soccer, and golf. Short-term interventions such as music listening, mindfulness training, self-talk, and natural visual stimuli have been shown as effective strategies to alleviate mental fatigue and enhance technical and cognitive performance in ball sports. However, their practical application in real-game environments requires further research and validation. Additionally, future research should explore defensive skills and tactical performance as viable directions for study.

Acute acetaminophen ingestion improves the recovery of neuromuscular fatigue following simulated soccer match-play

ObjectivesThis study aimed to investigate the impact of acute acetaminophen ingestion on the responses of neuromuscular function, biomarkers of muscle damage, and physical performance during the 72-hour recovery period following simulated soccer match-play. DesignThe study followed a crossover randomized, double-blind, placebo-controlled trial design. MethodsDuring the two experimental sessions, thirteen semi-professional male soccer players completed a 90-minute simulated soccer match, 60 min after oral ingestion of 1 g acetaminophen or placebo. Maximal voluntary contraction and twitch responses of the knee extensor muscles, elicited through electrical femoral nerve stimulation, were utilized to evaluate both peripheral fatigue (potentiated twitch force, Qtw,pot) and central fatigue (voluntary activation). Performance was assessed through countermovement jump and 20 m sprint tests. Creatine kinase and lactate dehydrogenase were also measured. ResultsSmaller reductions were observed in maximal voluntary contraction (−13.3 ± 7.5 % vs. −24.7 ± 11.1 %) and voluntary activation (−3.8 ± 4.4 % vs. −12.9 ± 5.4 %) in the acetaminophen compared to the placebo condition immediately after simulated soccer match-play (p < 0.05). Afterward, these parameters were recovered 24 h earlier in the acetaminophen session compared to the placebo session. Furthermore, the 20 m sprint performance was significantly better throughout the recovery period in the acetaminophen session compared to the placebo session. ConclusionsThe findings of this study showed that acute ingestion of 1 g of acetaminophen (1 h before exercise) attenuated the decrease in maximal voluntary contraction and voluntary activation levels after exercise, as well as improved 20 m sprint performance.

The Effect of Ischemic Preconditioning on Tennis Exercise Performance and the Recovery Subsequent to a Simulated Tennis Match: A Randomized Controlled Trial.

The purpose of this study was to investigate the effects of acute ischemic preconditioning (IPC) on tennis skill and physical exercise performance, as well as to explore whether 7-day repeated IPC (RIPC) accelerated fatigue recovery after a simulated tennis match. Twenty-nine male tennis-specific current students were randomly allocated into 1 of 2 groups: SHAM (n = 14, 3 × 5min at 20mm Hg) and IPC (n = 15, 3 × 5min at 220mm Hg). Participants in both groups engaged in acute IPC and RIPC interventions. After the first acute IPC intervention, assessments were conducted to evaluate tennis-specific skills and overall physical exercise capacity. Following completion of chronic RIPC interventions, all participants competed in a simulated tennis match specifically designed to induce fatigue. To evaluate recovery from this induced fatigue, physical exercise capacity tests were conducted at 24 and 48hours postmatch, allowing for an assessment of the participants' recovery capabilities over time. After the first acute intervention, notable differences were observed between the IPC and SHAM groups in their performance on the repeated-sprint ability test. Specifically, the total times recorded were significantly shorter in the IPC group compared with the SHAM group (IPC: 109.05 [2.70] vs SHAM: 114.57 [7.45]s, P = .012), and this trend was also reflected in their best times (IPC: 4.20 [0.18]s vs SHAM: 4.39 [0.30]s, P = .042), indicating an immediate benefit of the IPC intervention on sprint performance. After a 7-day RIPC intervention, significant changes were noted in the SHAM group's performance metrics postmatch. There was an increase (P < .001) in fatigue index from 22% (8%) to 30% (9%) during repeated-sprint ability test and a decrease in serve speed from 120.2 (17.5) to 106.7 (13.0)km/h (P = .002) and knee peek torque from 196.0 (49.0) to 162.7 (39)N (extension, 60°/s, P < .001) in the SHAM group 24hours postmatch, relative to the IPC group. Moreover, compared with the SHAM group, the IPC group showed a lower rate of perceived exertion during the match (P < .001) and a decrease in visual analog scale score (P = .026) 24hours postmatch, suggesting enhanced recovery and reduced perception of pain relative to the SHAM group. IPC could serve as a strategy to generate an ergogenic effect and recovery during training and competition.

Recovery patterns of low-frequency fatigue in elite youth soccer players after official match

This study aimed to analyze the associations between recovery of low-frequency fatigue, jump height and perceptual responses following official soccer matches. Forty-two male youth elite soccer players (age: 17.13±0.70 years; height: 179.17±5.94 cm; weight: 69.74±4.91 kg) participated in this study. Low-frequency fatigue, countermovement jump, perceived fatigue, muscle soreness and perceived recovery were assessed at -2h, +30 min, +24h and +48h relative to the match. Linear mixed models analysis showed that low-frequency fatigue was reduced at the match-end (ES=-0.679 [95% CI = -1.01; -0.34]; p&lt;.001) but returned to baseline after 24h (ES=0.149 [95% CI = -0.26; 0.56]; p=1.00). Perceptual responses were impaired for up to 48 hours following the match (ES=-0.868–1.174; p&lt;.001). Countermovement jump did not differ between any time point (ES=-0.204–0.216; p&gt;0.05). Additionally, the within-subject correlation analysis showed that low-frequency fatigue pre- to post-match changes presented moderate to large associations with perceived fatigue (rm[57]=-0.43; p&lt;.001), muscle soreness (rm[57]=-0.52; p&lt;.001) and perceived recovery (rm[57]=0.38; p=.003). The assessment of low-frequency fatigue could serve as an additional objective measurement for monitoring post-match fatigue, as findings suggest that young elite soccer players experience transient reductions following match-play, which are strongly correlated with subjective markers of recovery.

Effects of 8days intake of hydrogen-rich water on muscular endurance performance and fatigue recovery during resistance training.

Exercise-induced oxidative stress and inflammation can impair muscular function in humans. The antioxidant and anti-inflammatory properties of molecular hydrogen (H2) highlight its potential to be as an effective nutritional supplement to support muscular function performance in healthy adults. However, the effects of H2 supplementation on muscular endurance performance in trained individuals have not been well characterized. This study aimed to assess the effects of intermittent hydrogen-rich water (HRW) supplementation before, during, and after resistance training on muscular endurance performance, neuromuscular status, and subjective perceptual responses after a 48-h recovery period. This randomized, double-blinded, placebo-controlled cross-over study included 18 trained men aged 19.7 ± 0.9years. Participants in this study were instructed to consume 1,920mL of HRW or pure water (Placebo) daily for 7days. Additionally, participants were required to supplement with HRW or pure water five times during the training day (1,260mL total). This included drinking 210mL 30min and 1min before training, 210mL between training sets, 210mL immediately after training, and 420mL 30min into the recovery period. Participants performed half-squat exercises with the load set at 70% of one repetition maximum for six sets (half-squat exercise performed to repetitions failure each set). We measured the power output and number of repetitions in the free barbell half-squat used to assess muscular endurance performance in participants. The countermovement jump (CMJ) height, total quality recovery scale (TQRS), and muscle soreness visual analog scale (VAS) scores were measured to assess fatigue recovery status after training, as well as at 24 and 48h of recovery. The total power output (HRW: 50,866.7 ± 6,359.9W, Placebo: 46,431.0 ± 9,376.5W, p = 0.032) and the total number of repetitions (HRW:78.2 ± 9.5 repetitions, Placebo: 70.3 ± 9.5 repetitions, p = 0.019) in the H2 supplemented group were significantly higher than in the placebo group. However, there was no statistically significant difference (p< 0.05) between the H2 and placebo groups in CMJ, TQRS, and VAS. Eight days of intermittent HRW intake could significantly improve muscular endurance performance in trained individuals, making it a promising strategy for athletes or fitness enthusiasts looking to boost muscular endurance during resistance training or competitions. However, it should be noted that HRW intake alone may not be adequate to accelerate recovery from muscle soreness or fatigue following high-intensity training.

Analyzing the effects of competitive fatigue on body composition and functional capacities of youth elite handball players

Handball demands intense movements like rapid direction changes and physical contact. Consecutive competitions expose player fatigue and weaknesses due to the sport’s exhaustive nature. Therefore, the aims of this study are twofold: (i) to investigate the impact of competitive fatigue on the body composition of youth elite handball players, and (ii) to analyze the impact of concentrated competition on their functional capacity performance. Seventeen young male handball players (age: 16.2 years, height; 177.8 cm, body mass: 73.0 kg) were assessed twenty-four hours before (TM1) and after the competitive period (TM2) in body composition, static strength, lower- and upper-body explosive strength, speed, agility, balance, and flexibility indicators. A Wilcoxon Signed Rank Test was conducted to assess differences in body composition and functional capacities assessment between TM1 and TM2. Regarding results, body mass significantly increased in TM2 (p &lt; 0.01), while increases in waist circumference and body fat percentage were not statistically significant. Functional capacity assessments revealed a significant decline in jumping performance (CMJ and SJ; p ≤ 0.01). Speed and agility assessments showed worse performance in TM2, significantly increasing 30 m sprint time (p ≤ 0.01). Balance indicators showed no significant differences, with mixed results in performance across different conditions. In sum, evaluating vertical jumps and long-distance maximum speed (i.e., 30 meters) could be valid tests for measuring and controlling fatigue in young elite handball players. Future research should regularly monitor young handballers after the competition to analyze the entire fatigue recovery process.

Monitoring the heart rate variability of servicewomen of the Armed Forces of Ukraine during the legal regime of martial law

The article features the results of the analysis of heart rate variability of 30 female military personnel (n=30). The purpose of this study was to assess the state of regulatory mechanisms of the autonomic nervous system. The analysis of heart rate variability indicators reflects the general level of autonomic regulation, which is important for assessing the physical and psychological state of military personnel. The RRNN parameter had a median of 814.5 ms, which corresponds to the norm for healthy individuals and indicates a normal level of cardiac activity of females being under the research. The SDNN indicator, which characterizes the total effect of autonomic regulation of blood circulation, was 37.4 ms on the median, which also corresponds to the norm and indicates an adequate level of adaptation capabilities of the body. However, RMSSD was at the median below normal, indicating reduced recovery and high levels of stress among female military personnel. pNN50, which reflects the proportion of consecutive RR intervals differing by more than 50 ms, was also below normal, further confirming reduced parasympathetic activity. The LF index was 301.0 ms² on the median of female military personnel, which is at the lower limit of the norm. The result we obtained may indicate a reduced sympathetic influence or a general depletion of adaptation reserves. The VLF indicator, which characterizes neurohumoral regulation, was also below the norm, which indicates a possible depletion of the body's adaptive reserves. Such studies make it possible to detect signs of fatigue or insufficient recovery in time and take the necessary measures to optimize the training process and the performance of official duties. Our research confirms that heart rate variability is an important indicator of the body's adaptive capabilities, especially in the conditions of martial law, where stress and physical exertion are constant factors of influence.

The effect of tart cherry juice compared to a sports drink on cycling exercise performance, substrate metabolism, and recovery.

Tart cherries have low glycemic index, antioxidant and anti-inflammatory properties, and therefore may benefit performance and recovery from exercise. We determined the effects of consuming tart cherry juice versus a high-glycemic index sports drink on cycling performance, substrate oxidation, and recovery of low-frequency fatigue. Using a randomized, counter-balanced cross-over design, with one-month washout, 12 recreational cyclists (8 males and 4 females; 35±16y; VO2peak 38.2±7.4 ml/kg/min) consumed cherry juice or sports drink twice a day (300mL/d) for 4d before and 2d after exercise. On the exercise day, beverages (providing 1g/kg carbohydrate) were consumed 45min before 90min of cycling at 65%VO2peak, followed by a 10km time trial. Blood glucose, lactate, carbohydrate and fat oxidation, respiratory exchange ratio (RER), O2 cost of cycling, and rating of perceived exertion (RPE) were measured during the initial 90min of cycling. Muscle soreness, maximal voluntary contraction (MVC) and low-frequency fatigue were determined at baseline and after the time trial on the exercise day, and 30min after beverage consumption 24 and 48h later. There were no differences for time trial performance (17±3min cherry juice vs. 17±2min sports drink, p = 0.27) or any other measures between drink conditions. There were time main effects (p<0.05) for isometric MVC (decreasing) and low-frequency fatigue (increasing; i.e. decreased force at low relative to high stimulation frequencies), changing significantly from baseline to post-exercise and then returning to baseline at 24h post-exercise. Tart cherry juice was not effective for improving performance, substrate oxidation during exercise, and recovery from exercise, compared to a high-glycemic index sports drink.

NICER: A New and Improved Consumed Endurance and Recovery Metric to Quantify Muscle Fatigue of Mid-Air Interactions

Natural gestures are crucial for mid-air interaction, but predicting and managing muscle fatigue is challenging. Existing torque-based models are limited in their ability to model above-shoulder interactions and to account for fatigue recovery. We introduce a new hybrid model, NICER , which combines a torque-based approach with a new term derived from the empirical measurement of muscle contraction and a recovery factor to account for decreasing fatigue during rest. We evaluated NICER in a mid-air selection task using two interaction methods with different degrees of perceived fatigue. Results show that NICER can accurately model above-shoulder interactions as well as reflect fatigue recovery during rest periods. Moreover, both interaction methods show a stronger correlation with subjective fatigue measurement ( ρ = 0.978/0.976) than a previous model, Cumulative Fatigue ( ρ = 0.966/0.923), confirming that NICER is a powerful analytical tool to predict fatigue across a variety of gesture-based interactive applications.

Nurses’ Generational Differences of Burnout and Turnover Risk

This study aimed to determine the impact of nurse generation on (a) turnover risk factors (low meaning/joy in work, low resilience, high occupational fatigue, high burnout) and (b) turnover intentions before and during the COVID-19 pandemic. Survey methods were used to compare two samples of hospital nurses who completed online surveys in 2017 or 2021. The results were compared on burnout and turnover risk by generation. Results indicate that in 2017, high acute fatigue and low inter-shift recovery differed by nurse generation, with Baby Boomers (Boomers) being the least affected. Additionally, Boomers were the least likely to report a likelihood of leaving the hospital within 6-12 months. However, in 2021, Millennial nurses experienced significantly higher levels of low meaning and joy in work, low resilience, high acute fatigue, low inter-shift recovery, and high burnout than Generation X (GenX) and Boomers. Millennials were the most likely generation to report turnover intention. This leads to the conclusion that the pandemic may have worsened the work experience of millennial nurses and increased their risk of leaving hospital jobs and the profession.
