Long work hours and chronic insomnia are associated with needlestick and sharps injuries among hospital nurses in Taiwan: A national survey

Analysis of factors associated with needlestick injuries of clinical nurses by applying a human factor analysis and classification system: A nationwide cross-sectional survey

AIMS

This study aims to investigate the current situation of needlestick injuries (NSIs) of clinical nurses and identify associated factors by using the theoretical framework of the human factors analysis and classification system (HFACS).

DESIGN

A nationwide cross-sectional survey was conducted.

METHODS

Multi-stage sampling was used to investigate 3336 nurses in 14 Chinese hospitals. Descriptive statistics and univariate and multivariate logistic regression were employed to reveal the rate of NSIs and their associated factors.

RESULTS

A total of 970 nurses (29.1%) reported having experienced at least one NSI in the past year. The multivariate logistic regression analysis showed that good hospital safety climate and clinical nurses in intensive care unit (ICU) and emergency department had protective effects against NSIs compared with nurses in internal medicine department. The nurse, senior nurse, and nurse in charge have significantly increased the risk for NSIs compared with the associate chief nurse or above. Patients with poor vision but wearing glasses and poor vision but not wearing glasses were more prone to have NSIs. Working in the operating room compared with internal medicine, average weekly working time of >45 h compared with ≤40 h and poor general health led to increased risk of NSIs.

CONCLUSION

The rate of NSIs in clinical nurses was high in China. Individual factors including professional title, department, visual acuity and general mental health and organisational factors including weekly working hours and hospital safety atmosphere were significantly correlated with the occurrence of NSIs.

RELEVANCE TO CLINICAL PRACTICE

Nursing managers should focused on physical and psychological conditions of clinical nurses, and organisational support is required to enhance the hospital safety atmosphere.

NO PATIENT OR PUBLIC CONTRIBUTION

Contributions from patients or the public are irrelevant because this study aims to explore current situation and factors associated with NSIs in clinical nurses.

Stress begets stress: The moderating role of childhood adversity in the relationship between job stress and sleep quality among nurses

BACKGROUND

Nurses exhibit considerable variations in sleep quality and experience high job stress levels. Distal factors, such as childhood adversity, and proximal factors, both influence sleep quality. We investigated the moderating role of childhood adversity with job stress and sleep quality, and whether this aligns with the stress-sensitization or stress-amplification models.

METHODS

The impact of job stressors' total score and its dimensions on sleep quality was analyzed using traditional linear regression models and the extreme gradient boosting machine learning algorithm. The hierarchical regression examined the moderating role of childhood adversity in the relationship between job stress and sleep quality. An interactive tool was used to visualize the results.

RESULTS

Among the dimensions of job stress, "time allocation and workload" strongly correlated with sleep quality, followed by "nursing profession and work problems," "patient care issues," "management and interpersonal problems," and "working environment and equipment problems." The moderating role of childhood adversity in the relationship between different dimensions of job stressors (except working environment and equipment problems) and sleep quality aligns with the stress-sensitization model.

LIMITATIONS

This study was susceptible to recall bias and objective sleep data were unavailable. Cross-sectional study design was used, thus limiting causal inferences. Finally, the moderating effect of childhood adversity on subsequent stress among nurses remains unclear.

CONCLUSION

Childhood adversity and job stress were integrated into a stress-sensitization model, providing a nuanced and specific examination of sleep quality. Healthcare policymakers should focus on job stress and childhood adversity, improve nurses' sleep quality, and ultimately benefit patient care and outcomes.

A survey of bloodborne occupational exposure protection behavior among qualified Chinese midwives: A cross-sectional study

Background

Bloodborne occupational exposure is a major public health concern of the China Health Commission, especially among midwives who are at high risk among healthcare workers. Knowledge of occupational exposure and appropriate protective behaviors play important roles in reducing occupational exposure. The purpose of this study was to understand the knowledge and level of protection against bloodborne occupational exposure among midwives in China.

Methods

This was a multi-center, cross-sectional study. Midwives from hospitals that are members of Infectious Disease Nursing Committee of Chinese Nursing Association were selected as survey participants from February 2019 to February 2022 using a judged sampling method. Data were collected by using a self-developed questionnaire for Chinese midwives to report their current knowledge and behavior related to bloodborne occupational exposure protection.

Results

A total of 2850 questionnaires were distributed and 2742 valid questionnaires were obtained, resulting in an effective rate of 96.21 %. Midwives scored 2742 (6.495 ± 1.529) points for their knowledge about bloodborne occupational exposure protection, with the level and type of hospital being independent factors affecting the midwives' knowledge of bloodborne occupational exposure protection (χ2 = 27.284, P = 0.038; χ2 = 28.374, P = 0.000). Of the midwives, 1460 were qualified for bloodborne occupational exposure protection behavior, with a qualified rate of 53.25 %. Working years (χ2 = 9.372, P = 0.002) and working hours (χ2 = 13.933, P = 0.000) were also the independent factors for bloodborne occupational exposure protective behavior in midwives.

Conclusion

Chinese midwives possess relatively good knowledge of bloodborne exposure protection against bloodborne infectious diseases, but their behavioral level is not optimistic. Improvements to both knowledge and behavioral level of bloodborne occupational exposure protection are necessary.

A scoping review of sleep education and training for nurses

BACKGROUND

Shift work and resulting sleep impairment among nurses can increase their risk for poor health outcomes, occupational injuries, and errors due to sleep deficiencies. While sleep education and training for nurses has been recommended as part of a larger fatigue risk management system, little is known about training programs designed specifically for nurses.

OBJECTIVE

Investigate the literature for current sleep education or training programs specifically for shift working nurses, with intent to assess training content, delivery characteristics, and outcome measures.

DESIGN

A scoping review conducted October 2020 through September 2021.

METHODS

The bibliographic databases Cumulative Index of Nursing and Allied Health (CINAHL), Scopus, PubMed, and NIOSHTIC-2 were searched using words such as "nurse," "sleep hygiene," "shift work," and "education". Studies were included if they: 1) were original research; 2) discussed sleep education, training, or sleep hygiene interventions; 3) included a study population of nurses engaging in shift work; 4) focused on sleep as a primary study measure; 5) were written in English language; and 6) were published in 2000 or later.

RESULTS

Search results included 17,237 articles. After duplicates were removed, 14,620 articles were screened. Nine articles were found to meet established criteria. All studies included sleep hygiene content in the training programs, with five studies adding psychological and/or behavior change motivation training to support change in nurse sleep habits. Three studies added specific training for nurses and for managers. Delivery modes included in-person training of various lengths and frequency, mobile phone application with daily engagement, an online self-guided presentation, and daily reading material coupled with audio training. Pittsburgh Sleep Quality Index and Epworth Sleepiness Scale were the outcome measures most frequently used. Although studies demonstrated improved sleep measures, most were pilot studies testing feasibility.

CONCLUSION

Although there is a paucity of studies focused on sleep education and training for shift working nurses, we found the inclusion of sleep hygiene content was the only common characteristic of all nine studies. The variability in training content, delivery methods, and outcome measures suggests further research is needed on what constitutes effective sleep education and training for nurses.

Shift work organization on nurse injuries: A scoping review

BACKGROUND

Extended work hours and shift work can result in mistimed sleep, excessive sleepiness, and fatigue, which affects concentration and cognition. Impaired concentration and cognition negatively affect employee safety.

OBJECTIVE

To examine the evidence of the impact of shift work organization, specifically work hours and scheduling, on nurse injuries including needlestick and sharps injuries, drowsy driving and motor vehicle crashes, and work-related accidents causing a near miss or actual injury to the nurse.

METHODS

A scoping review was conducted using search results from five bibliographic databases.

RESULTS

Through database searching, 7788 articles were identified. During the title and abstract screening, 5475 articles were excluded. Full text screening eliminated 1971 articles. During the data extraction phase, 206 articles were excluded leaving 34 articles from 14 countries in the scoping review. The results of the review suggest a strong association in nurses between long work hours and overtime and an increased risk for needlestick and sharps injuries, drowsy driving and motor vehicle crashes, and other work-related accidents. Rotating shifts increase the risk for needlestick and sharps injuries and other work-related accidents while night and rotating shifts increase the risk for drowsy driving and motor vehicle crashes.

CONCLUSIONS

Proper management of work hours and scheduling is essential to maximize recovery time and reduce or prevent nurse injuries. Nurse leaders, administrators, and managers, have a responsibility to create a culture of safety. This begins with safe scheduling practices, closely monitoring for near miss and actual nurse injuries, and implementing evidence-based practice strategies to reduce these occurrences.

Validity and reliability of the Japanese version of the Nursing Performance Instrument

AIM

Work performance of nurses is a critical aspect that concerns the safety of both nurses and patients, but also secondarily influences nurses' turnover due to serious fatigue and burnout. Monitoring nursing performance as well as fatigue is important for appropriate safety management of patients and nurses, and the development of a monitoring tool is essential. The Nursing Performance Instrument (NPI) can provide comprehensive and brief monitoring of nursing performance. This study aimed to verify the validity and reliability of a Japanese version of the NPI (NPI-J).

METHODS

A cross-sectional study was conducted on nurses who work in inpatient care across five Japanese hospitals. We considered appropriate factor numbers with parallel analysis and the Velicer's minimum average partial test. The construct validity was evaluated using exploratory factor analysis, confirmatory factor analysis (CFA), and Pearson's correlation analysis. Cronbach's alpha was calculated for the internal consistency.

RESULTS

A three-factor model eventually showed acceptable fit indices in the CFA. Moreover, the correlation results among the three factors indicated discriminant validity comparable to the original NPI. The correlation results with acute fatigue, chronic fatigue, and burnout verified convergent validity. Internal consistency was insufficient.

CONCLUSION

The NPI-J demonstrated acceptable construct validity. This instrument can assess nurses' perceptions of their performance by measuring each item. Future work on the reliability of the sub-concepts will require additional items or reliability testing based on generalizability theory and item response theory.

Prevalence and influence factors of occupational exposure to blood and body fluids in registered Chinese nurses: a national cross-sectional study

Background

Occupational exposure to blood and body fluids poses a threat to medical providers and to nurses especially. This harm is not only physical, but psychology as well and can ultimately impact patient safety. This study aims to understand the prevalence of occupational exposure to blood and body fluids among Chinese registered nurses and explores the factors that influence this exposure.

Methods

A cross-sectional online survey was conducted for 31 province-level divisions in China, using a self-created questionnaire entitled Status Survey on Occupational Exposure in Nurses. Descriptive statistics were used to describe both the demographic characteristics of the respondents and the characteristics of occupational exposure. Categorical variables were presented as frequencies and percentage, and the relationship between possible influential factors and the occurrence of occupational exposure was determined using binary logistic regression.

Results

Out of a total of 20,791 nurses analyzed, over half (52.1%) of them had experienced occupational exposure to blood or body fluids, but over 1/3 (34.6%) of them did not ever report their exposures to a supervisor/official. The top three causes of under-reporting were: the source patient failed to test positive for infectious pathogens (43.6%), perception of a burdensome reporting process (24.6%), and indifferent attitude towards being infected (16.9%). Nurses who worked over 8 hours per day had higher risks of exposure (OR 1.199, 95% CI 1.130 to 1.272, P < 0.001, respectively). The occupational exposure risk from providing 1–2 types of PPE is 1.947 times that of providing 9–10 types of PPE (OR 1.947, 95% CI 1.740 to 2.178, P < 0.001). Likewise, the occupational exposure risk of providing 1–2 types of safety-engineered injection devices is 1.275 times of that of providing 5–6 types (OR 1.275, 95% CI 1.179 to 1.379, P < 0.001).

Conclusions

Occupational exposure to blood and body fluids in registered nurses is common, but the rate of under-reporting such exposure is high. Implementing engineered “sharp” injury prevention devices, following exposure prevention procedures, giving sufficient education and training to healthcare personnel on exposure prevention and control, and developing exposure reporting policies are all steps that can both reduce exposure and increase its reporting.

Patterns of Systemic Disease Diagnoses among Medical Professionals in Taiwan: Statistical Analysis and Data Mining

INTRODUCTION

Although high-risk work environments and heavy workload expose medical professionals to long-term risks of disease, no comprehensive analysis has been conducted on the corresponding risks of diseases to each type of medical professionals. This study pre-analyzed the risks of medical professionals in developing various systemic diseases in Taiwan to provide a comprehensive examination of the differences between each type of systemic disease.

METHODS

From the secondary databases of 2002-2013, 15,407 medical professionals were selected for analysis. A chi-squared test and logistic regression were performed to identify the relationship between types of medical professionals and systemic diseases. The life trajectories of diagnosis sequence of the medical professionals were illustrated accordingly.

RESULTS

The physicians were the most vulnerable to infectious, parasitic, and digestive diseases. This was possibly associated with their work characteristics and occupational risks.

CONCLUSION

According to the life trajectories, all types of the medical professionals exhibited a similar trend in the orders of risks to each type of systemic disease, which suggests that their work environment exposes them to real risks of health hazard.

The impact of COVID-19 pandemic on sleep quality in healthcare workers in Turkey

Background

The COVID-19 pandemic has caused serious concerns and psychological distress globally. Healthcare workers remain one of the most affected groups due to life threatening risks in addition to increased working hours and labor intensity. All these factors may affect sleep quality of this population. The aim of this study is to evaluate the sleep behaviors of healthcare professionals working in secondary and tertiary hospitals in a large population in Turkey and to show how sleep quality is affected during the pandemic process using the easily applicable Jenkins Sleep Scale (JSS). The population of this cross-sectional descriptive study consists of two pandemic hospitals determined in Kahramanmaraş province. In our questionnaire, we asked subjective sleep quality, sleep time, time to fall asleep, total sleep time, and medication use. We also used JSS Turkish version (JSS-TR) to assess sleep quality and the Epworth Sleepiness Scale (ESS) for increased daytime sleepiness.

Results

Healthcare workers who participated in our survey reported that they started to go to bed later, fell asleep later (mean: 41.75 ± 35.35 min), their total sleep time (mean: 6.67 ± 1.88 h) was shortened, and they needed medication to sleep more (5.7%) after the COVID-19 pandemic. During the COVID-19 pandemic, bedtime behavior after 24:00 decreased from 80.1 to 43.9% of those who previously went to bed before 24:00. For those who went to bed after 24:00 before, it increased from 19.9 to 56.1%. In addition, sleep quality as assessed by subjective and JSS significantly deteriorated after the COVID-19 pandemic. Excessive daytime sleepiness increased. Those with ESS > 10 before and after COVID-19 were 3.9% and 14.1%, respectively (p < 0.001).

Conclusions

The COVID-19 pandemic has significantly adversely affected the sleep behavior and sleep quality of healthcare professionals. The JSS is an easily applicable scale for assessing sleep quality in large population studies.

Association of overtime work and obesity with needle stick and sharp injuries in medical practice

BACKGROUND

Needle stick and sharps injuries (NSIs) may cause infections among medical personnel. Obesity and overtime work among medical personnel increase the incidence of work injuries.

AIM

To investigate whether overtime work and obesity increase the risk of NSIs.

METHODS

This cross-sectional study used the data of 847 hospital personnel, including 104 doctors, 613 nurses, 67 medical laboratory scientists, 54 specialist technicians, and nine surgical assistants. Of them, 29 participants notified the hospital of having at least one NSI in 2017. The data collected included age, overtime work, body mass index, medical specialty such as doctor or nurse, and professional grade such as attending physician or resident. The χ 2 and Fisher's exact tests were used to compare categorical variables. Multiple logistic regression analysis and the Sobel test were used to assess the risk of NSIs.

RESULTS

Overtime work, body weight, and medical specialty were significantly associated with NSIs (P < 0.05). After adjustment for risk factors, heavy overtime work was an independent risk factor for NSIs, and healthy body weight and nursing specialty were independent protective factors against NSIs. After adjustment for risk factors, medical personnel with healthy body weight has half as many NSIs as those with unhealthy body weight; the proportion of NSIs in doctors with healthy body weight was 0.2 times that in doctors with unhealthy body weight; the proportion of injuries among residents was 17.3 times higher than that among attending physicians; the proportion of injuries among junior nurses was 3.9 times higher than that among experienced nurses; the proportion of injuries among nurses with heavy overtime work was 6.6 times higher than that among nurses with mild overtime work; and the proportion of injuries among residents was 19.5 times higher than that among junior nurses. Heavy overtime work mediated the association of medical specialty with NSIs.

CONCLUSION

In addition to promoting the use of safety needles and providing infection control education, managers should review overtime schedules, and medical personnel should be encouraged to maintain a healthy weight.

Is burnout a mediating factor between sharps injury and work-related factors or musculoskeletal pain?

BACKGROUND

Burnout, musculoskeletal pain, and sharps injuries (SIs) affect medical workers.

AIM

To establish a model between SIs, burnout, and the risk factors to assess the extent to which burnout affects SIs.

METHODS

This questionnaire was used for an observational and cross-sectional study, which was based on members at a hospital affiliated with a medical university in Taichung, Taiwan, in 2020. The valid responses constituted 68.5% (1734 of 2531). The items were drawn from the Nordic Musculoskeletal Questionnaire and Copenhagen burnout inventory and concerned work experience, occupational category, presence of chronic diseases, sleep duration, overtime work, and work schedule. Factor analysis, chi-square test, Fisher exact test, Multiple linear, logistic regression and Sobel test were conducted. The present analyses were performed using SAS Enterprise Guide 6.1 software (SAS Institute Inc., Cary, NC, United States), and significance was set at P < 0.05.

RESULTS

Personal and work-related burnout ranks, sex, work experience ranks, occupational groups, drinking in the past month, sleep duration per day, presence of chronic diseases, overtime work ranks, and work schedule were associated with SIs. Frequent upper limb and lower limb pain (pain occurring every day or once a week) determined to be related to SIs. High personal burnout (> Q3) and high work-related burnout (> Q3) mediated the relationship between SIs and frequent lower limb pain. Similarly, frequent lower limb pain mediated the relationship of SIs with high personal and high work-related burnout. High personal and high work-related burnout mediated the relationships of SIs with overtime work and irregular shift work. The mediating model provides strong evidence of an association between mental health and SIs.

CONCLUSION

Burnout was determined to contribute to SIs occurrence; specifically, it mediated the relationships of SIs with frequent musculoskeletal pain, overtime work, and irregular shift work.

Risk Factors of Needlestick and Sharp Injuries among Health Care Workers at Sanglah Tertiary Hospital

Background: Needlestick and sharp injuries (NSIs) remain one of the main occupational hazards among health care workers (HCWs) that lead to blood-borne pathogen exposure. Purpose: This study examined the risk factors for NSIs among HCWs at a tertiary referral hospital in Bali. Methods: A case-control study was conducted at Sanglah General Hospital, Bali, involving 171 HCWs, divided into 81 cases and 90 control subjects. The sample was selected using a simple random sampling technique. Data were collected using questionnaires and analyzed using multiple logistic regression. Results: The majority of respondents had experienced NSIs once, in the morning shift, and had affected an individual’s hands. The most frequent activity leading to NSIs was giving an injection and most of the situations causing NSIs involved accidental self-action, and recapping needles. Factors associated with the incidence of NSIs were work career or experience of <5 years (p < 0.01; adjusted odds ratio [AOR]=5.04; 95% confidence interval [CI] = 2.04–12.42), non-compliance with working procedures (p = 0.01; AOR = 2.47; 95%CI= 1.26–4.82), female HCWs (p = 0.03; AOR = 2.21; 95% CI = 1.01–4.55), and unsafe workplace conditions (p = 0.04; AOR = 2.23; 95% CI = 1.01–4.92). Conclusion: Personal and environmental factors such as gender, work experience, compliance with working procedures, and workplace conditions are among the risk factors for NSIs. Occupational health and safety policies and programs focusing on the relevant factors, accompanied by adequate supervision, are necessary to reduce the risk of NSIs occurring.

Cross-sectional study assessing the risk of needlestick injury from an insulin pen among nursing care providers

Objective

Needlestick injuries caused by insulin pen injection are a serious occupational hazard for health care workers in China. We evaluated the prevalence of stick injuries with insulin pen injection and identified associated risk factors.

Methods

This cross-sectional survey was conducted from 1 October to 30 November 2018 in two tier three hospitals in Chongqing, China. Self-administered questionnaires were developed by the Chinese Nursing Association Diabetes Care Special Committee. We analyzed associations between potential risk factors and injuries at different operational steps.

Results

A total 233 of 302 (77%) participants (mean age 28.5±5.3 years) reported a needlestick incident. Most respondents (49%) had 3 to 10 years’ working experience and had received injection safety training. Most needlestick injuries occurred while recapping needles after injection. The risk of injury was significantly associated with department and job position. The injury rate increased with increased number of years worked. Respondents with ≥10 years working experience reported the highest needle-capping injury rate (88%): odds ratio 1.93, 95% confidence interval, 1.01 to 3.69.

Conclusion

Recapping needles after injection showed the highest risk for stick injury with an insulin pen. Nurses in the surgery department and those with longer work histories were more likely to be injured.

The association between shift patterns and the quality of hand antisepsis in a neonatal intensive care unit: An observational study

BACKGROUND

Healthcare-associated infections represent a major burden in neonatal intensive care units. Hand antisepsis is the most important tool for prevention, however, compliance among healthcare workers remains low.

OBJECTIVES

To prospectively evaluate the influence of different work shifts (extended working hours, night shifts) on the quality of healthcare workers' hand antisepsis.

DESIGN

Observational study.

SETTINGS

Two equivalent "Level III" neonatal intensive care units at the University Hospital Vienna, Austria.

PARTICIPANTS

Seventy healthcare workers, 46 nurses and 24 physicians.

METHODS

The Semmelweis Scanner, an innovative training device assessing the quality of hand antisepsis with an ultraviolet dye labelled alcohol-based hand rub, was employed to collect data on the hand surface coverage achieved during hand antisepsis of participants. It provides visual feedback of appropriately versus inappropriately disinfected areas of the hand and can also be used for the objective quantification of hand surface coverage with the hand rub. Measurements were performed before and after 12.5 h (h) day and night shifts (nurses), as well as before and after regular 8 h day shifts and extended 25 h shifts (physicians). To avoid any bias caused by residual ultraviolet marker, scans had to be separated by 24 h periods. Primary outcome was the hand surface coverage with the hand rub: Hand scans were categorized as "passed" if an appropriate quality of hand hygiene, defined as a minimum 97% coverage of hand surface, was achieved. A generalized mixed model was used to analyse the data accounting for repeated measurements.

RESULTS

Seventy healthcare workers performed a total of 485 scans. Nineteen scans had to be excluded, resulting in 466 scans for further analyses. A difference in the predicted probability of achieving appropriate hand antisepsis was found between the beginning and end of extended shifts: In physicians, adequate hand antisepsis was remarkably reduced after 25 h shifts (predicted probability 99.4% vs 78.8%), whereas there was no relevant difference between the beginning and end of 8 h day shifts (92.2% vs 97.3%). In nurses, a relevant difference was found between the beginning and end of 12.5 h day shifts (88.6% vs 73.6%). This difference was not found for 12.5 h night shifts. The most frequently missed area on the hands was the right dorsum.

CONCLUSION

The quality of hand antisepsis of healthcare workers in neonatal intensive care units may be associated with long working hours.

Trust in leader as a pathway between ethical leadership and safety compliance

Purpose

Although a great number of studies have established the important role of leadership in workplace safety, it appears researchers are yet to consider the role that trust in leaders could play between ethical leadership and safety compliance within healthcare. To address that imbalance, this study aims to investigate the relationship between ethical leadership and safety compliance, with trust in the leader as the mediator.

Design/methodology/approach

Data were collected in three time periods from 237 hospital staff nurses (76.8 per cent women and 23.2 per cent men). Ordinary least squares regression-based path analysis using PROCESS for statistical package for the social sciences (SPSS) macro was used to test the hypotheses.

Findings

Results showed that ethical leadership was positively related to trust in a leader but was not related to safety compliance. In addition, trust in leader was positively related to safety compliance and also mediated the positive relationship between ethical leadership and safety compliance.

Research limitations/implications

The data were collected within healthcare organisations in a few localities in Nigeria, making it difficult to generalise the findings beyond the current sample let alone the entire country or even continent.

Practical implications

The findings imply that ethical leadership may not be directly effective in improving the safety compliance of subordinate nurses unless such a leader first develops a trust-based relationship with the subordinates.

Originality/value

The current study builds on and extends the burgeoning research in the area of leadership and employee outcome by investigating not only the direct relationship between ethical leadership and safety compliance but also incorporating trust in a leader as a mediator of this relationship.

Work-life support: the key to managers’ happiness

Purpose

Building on the conservation of resource theory, the authors posit work-life support as an essential resource for middle managers. This paper aims to explore the positive association between work-life support, positive emotion, job satisfaction and happiness. The paper also assesses the moderating role of work pressure on work-life support and positive emotion relationship on the one hand and flextime on positive emotion and job satisfaction on the other.

Design/methodology/approach

Data collected from 512 middle managers of small and medium-sized firms including manufacturing, service and finance sectors in Taiwan were used to test the hypotheses.

Findings

The results reveal that work pressure strengthens the effect of work-life support on positive emotions, whereas time flexibility weakens the effect of positive emotion on job satisfaction. Work-life support positively influences happiness through the intervening variables of positive emotion and job satisfaction.

Practical implications

The paper highlights the importance of creating a positive work environment, as empowering middle managers with work-life support can help them handle work pressure and work-life conflict. The negative influence of flextime on positive emotion and job satisfaction highlights the need for effective handling of flextime.

Originality/value

This paper examines the work-life support and happiness of middle managers in the Chinese cultural context which has been under-explored. This paper expands the external validity of previous research results of Western samples by finding the positive influence of work pressure on work-life fit and positive emotion and negative influence of flextime on positive emotion and job satisfaction link.

Effects of Nocturnal Sleep Quality on Diurnal Cortisol Profiles and Attention in Nurses: A Cross-Sectional Study

Objective:

Low sleep quality (LSQ) activates the hypothalamic–pituitary–adrenal (HPA) axis and is related to arousal. Nursing staff, who work in shifts, tend to exhibit LSQ, which affects the level of vigor after awakening. This study investigated the effects of nocturnal sleep quality on diurnal cortisol profiles and sustained attention in day-shift nurses.

Method:

This study adopted a prospective cross-sectional design. Participants were recruited from a university-affiliated hospital in northern Taiwan. In the initial stage of this study, the Chinese Pittsburgh Sleep Quality Index (PSQI) Questionnaire was administered to 199 participants to categorize them as either LSQ (PSQI > 5) or high sleep quality (HSQ; PSQI ≤ 5). Participants were then randomly sampled from the two groups. Nocturnal sleep data and four diurnal saliva samples were collected for each participant. Sustained attention was measured before they started work. A total of 32 and 29 participants in the HSQ and LSQ groups, respectively, completed the data collection process.

Results:

Compared with the HSQ group, the LSQ group exhibited earlier wake-up times ( p = .02), a flatter cortisol awakening response (CAR) slope ( p < .01), a flatter morning-to-evening slope ( p < .01), and prolonged reaction speed and mean reaction time before starting work ( p < .01).

Conclusion:

Compared with the HSQ group, the LSQ group exhibited impaired HPA-axis regulation, with a flatter CAR and diurnal cortisol slope and poor sustained attention in the morning. Nursing staff are advised to achieve HSQ to improve attention and performance levels and maintain optimum work safety.

The associations of workload, individual and organisational factors on nurses' occupational injuries

AIMS AND OBJECTIVES

To determine the prevalence and type of occupational injuries in nurses and their associations with workload, working shift, and nurses' individual and organisational factors.

BACKGROUND

Nurses are vulnerable to occupational injuries due to the nature of their job.

DESIGN

A cross-sectional correlational design (based on STROBE Statement) was conducted.

METHODS

This study was conducted among 616 nurses of four public hospitals located in four different provinces in Iran. Data were collected using three questionnaires including an organisational and demographic questionnaire, an occupational injuries checklist and the NASA-TLX questionnaire (about mental workload). Chi-square test, one-way ANOVA and multivariate logistic regression were used in SPSS version 23.0 for statistical analysis.

RESULTS

Blood and body fluid exposures had the highest prevalence (47.4%) among all injuries. Needlestick injuries showed a significant relation with gender, age, number of shifts in a month and work experience. With increase in mental workload, needlestick injuries increase by 35%. Also, injuries reported by nurses working in rotating shifts were 15%-53% more than nurses working in fixed shifts.

CONCLUSION

Working in rotating shifts and work overload was significantly related to all injuries. Decreasing nurses' mental workload, introducing guidelines and efficient training in shift work schedules can help decrease occupational injuries among nurses.

RELEVANCE TO CLINICAL PRACTICE

In order to reduce occupational injuries among nurses, in addition to incorporating advanced management and technology, it is necessary to pay attention to psychosocial, individual and organisational risk factors related to occupational injuries and their frequency in nurses. Also, reducing personnel's mental and occupational pressure should be considered.

Predicting needlestick and sharps injuries and determining preventive strategies using a Bayesian network approach in Tehran, Iran

OBJECTIVES

Recent studies have shown that the rate of needlestick and sharps injuries (NSIs) is unacceptably high in Iranian hospitals. The aim of the present study was to use a systematic approach to predict and reduce these injuries.

METHODS

This cross-sectional study was conducted in 5 hospitals in Tehran, Iran. Eleven variables thought to affect NSIs were categorized based on the Human Factors Analysis and Classification System (HFACS) framework and modeled using a Bayesian network. A self-administered validated questionnaire was used to collect the required data. In total, 343 cases were used to train the model and 50 cases were used to test the model. Model performance was assessed using various indices. Finally, using predictive reasoning, several intervention strategies for reducing NSIs were recommended.

RESULTS

The Bayesian network HFACS model was able to predict 86% of new cases correctly. The analyses showed that safety motivation and fatigue were the most important contributors to NSIs. Supervisors' attitude toward safety and working hours per week were the most important factors in the unsafe supervision category. Management commitment and staffing were the most important organizational-level factors affecting NSIs. Finally, promising intervention strategies for reducing NSIs were identified and discussed.

CONCLUSIONS

To reduce NSIs, both management commitment and sufficient staffing are necessary. Supervisors should encourage nurses to engage in safe behavior. Excessive working hours result in fatigue and increase the risk of NSIs.

The associations of occupational hazards and injuries with work environments and overtime for nurses in China

Occupational hazards (OHs) and occupational injuries (OIs) may contribute to nurses needing sick time and to a high financial burden for hospitals. There is little published literature about nurse-reported OHs/OIs and their relationships with work environments and working overtime in China. This study was designed to describe Chinese hospital registered nurses' OHs/OIs and to explore the associations between work environments, working overtime, and nurse-reported OHs/OIs. This cross-sectional study was conducted in Guangdong province in China in 2014. The sample included 1,517 nurses from 111 medical/surgical units in 23 hospitals. The Practice Environment Scale of the Nursing Work Index was used to measure work environment. Overtime was calculated by subtracting scheduled work hours from actual work hours. Six items were used to measure nurse-reported OHs/OIs. Descriptive statistics, Chi-square tests, and two-level logistic regression models were used to analyze the data. The percentages of nurses reporting OHs/OIs occurred in the year before the survey ranged from 47% to 80%. Nurses who worked in good (vs. poor) unit work environments were less likely to experience OHs/OIs (Odds ratio [OR] = 0.65-0.68, p < .05). Nurses who worked overtime (OR = 1.19-1.33, p < .05) and in Level 3 (largest) hospitals (OR = 1.45-1.80, p < .05) were more likely to experience OHs/OIs. We found that OHs/OIs were prevalent among hospital nurses in China. Better work environment and less nurse overtime were associated with fewer nurse OHs/OIs.

From job stress to intention to leave among hospital nurses: A structural equation modelling approach

AIMS

The aim of this study was to examine the structural relationships linking job stress to leaving intentions through job satisfaction, depressed mood and stress adaptation among hospital nurses.

BACKGROUND

High turnover among nurses is a global concern. Structural relationships linking job stress to leaving intentions have not been thoroughly examined.

DESIGN

Two nationwide cross-sectional surveys of full-time hospital staff in 2011 and 2014.

METHODS

The study participants were 26,945 and 19,386 full-time clinical nurses in 2011 and 2014 respectively. Structural equation modelling was used to examine the interrelationships among the study variables based on the hypothesized model. We used cross-validation procedures to ensure the stability and validity of the model in the two samples.

RESULTS

There were five main paths from job stress to intention to leave the hospital. In addition to the direct path, job stress directly affected job satisfaction and depressed mood, which in turn affected intention to leave the hospital. Stress adaptation mitigated the effects of job stress on job satisfaction and depressed mood, which led to intention to leave the hospital. Intention to leave the hospital preceded intention to leave the profession. Those variables explained about 55% of the variance in intention to leave the profession in both years.

CONCLUSION

The model fit was good for both samples, suggesting validity of the model. Strategies to decrease turnover intentions among nurses could focus on creating a less stressful work environment, increasing job satisfaction and stress adaptation and decreasing depressed mood. Hospitals should cooperate in this issue to decrease nurse turnover.
