Interruptions Experienced by Emergency Nurses: Implications for Subjective and Objective Measures of Workload

Development and Evaluation of Psychometric Properties of a Chinese Version Questionnaire for Measuring Emergency Nursing Interruptions

Nursing interruptions occur frequently and often have adverse outcomes, threatening patient safety. Emergency departments have a high incidence of nursing interruptions owing to the concentration of critically ill patients and frequent emergencies. Current research mainly focuses on large hospitals and uses observation and interview methods. Therefore, there is a need to develop tools for measuring emergency nursing interruptions. This study develops a survey questionnaire on emergency nursing interruptions. It tests its validity and reliability by building on the conceptual framework of emergency nursing interruption proposed in the literature. Specifically, we develop a test version of the emergency nursing interruption survey questionnaire using a Delphi expert inquiry and preinvestigation. We selected 1047 emergency nurses in 22 provinces and autonomous regions of China to participate in the survey by completing the questionnaire between June and July 2023 to evaluate the validity and reliability of the questionnaire. The final questionnaire comprised 26 items across 5 dimensions-sources, types, interrupted nursing activities, consequences of interrupted nursing activities, and management of nursing interruptions. The content validity indexes were 0.948 at scale level and 0.842-1.000 at item level. We used exploratory factor analysis (EFA) to extract five common factors with a cumulative variance contribution rate of 66.550%. The results of the confirmatory factor analysis (CFA) demonstrated a good model fit. Cronbach's α coefficient of the questionnaire was 0.912, split-half reliability was 0.846, and the retest reliability calculated using the intraclass correlation coefficient was 0.915. To ensure the structural validity of the scales, EFA and CFA were conducted using two different datasets. Thus, the questionnaire showed good validity and reliability and can be used to evaluate how nurses understand emergency nursing interruptions.

Experiences of compassion fatigue among Generation Z nurses in the emergency department: a qualitative study in Shanghai, China

BACKGROUND

Due to the unique working environment and nature of work in emergency departments, nurses are prone to experiencing compassion fatigue (CF), leading to job burnout and attrition. As more Generation Z (Gen Z) nurses enter the emergency department with distinct personality traits compared to previous generations, studying their experiences with CF will inform future management strategies.

METHODS

The qualitative phenomenological research method was utilised to investigate CF among Gen Z emergency nurses at a hospital in Shanghai, China. Data were collected through face-to-face semi-structured interviews and analyzed using Colaizzi's seven-step phenomenological analysis method. Study participants were purposively selected.

RESULTS

Three main themes and nine sub-themes emerged from the study: secondary traumatic stress, including physiological symptoms, psychological symptoms, and behavioral changes; cumulative effects, including impaired empathy, interference with family life, and post-traumatic growth (PTG); coping strategies, including cognitive reconstruction, seeking support, and facilitating action.

CONCLUSIONS

The aim of this study is to investigate the experience of CF among Gen Z emergency nurses, providing managers with a reference for future management strategies. The significance of multi-dimensional support for Gen Z emergency nurses is underscored by our findings. Additionally, interventions that enhance resilience and competency can facilitate their psychological transformation after experiencing CF and promote accelerated personal growth.

Quantifying emergency department nursing workload at the task level using NASA-TLX: An exploratory descriptive study

BACKGROUND

Emergency departments (ED) nurses experience high mental workloads because of unpredictable work environments; however, research evaluating ED nursing workload using a tool incorporating nurses' perception is lacking. Quantify ED nursing subjective workload and explore the impact of work experience on perceived workload.

METHODS

Thirty-two ED nurses at a tertiary academic hospital in the Republic of Korea were surveyed to assess their subjective workload for ED procedures using the National Aeronautics and Space Administration Task Load Index (NASA-TLX). Nonparametric statistical analysis was performed to describe the data, and linear regression analysis was conducted to estimate the impact of work experience on perceived workload.

RESULTS

Cardiopulmonary resuscitation (CPR) had the highest median workload, followed by interruption from a patient and their family members. Although inexperienced nurses perceived the 'special care' procedures (CPR and defibrillation) as more challenging compared with other categories, analysis revealed that nurses with more than 107 months of experience reported a significantly higher workload than those with less than 36 months of experience.

CONCLUSION

Addressing interruptions and customizing training can alleviate ED nursing workload. Quantified perceived workload is useful for identifying acceptable thresholds to maintain optimal workload, which ultimately contributes to predicting nursing staffing needs and ED crowding.

Cognitive mental workload of emergency nursing: A scoping review

AIM

Emergency nurses work in an environment of high cognitive mental workload. Excessive cognitive mental workload may result in patient harm and nurses' burnout. Therefore, it is necessary to understand nurses' subjective experience of cognitive workload. This scoping review aimed to curate literature about the subjective experience of cognitive mental workload reported by nurses and psychometric measures of the phenomenon.

DESIGN

The scoping review was conducted in accordance with JBI methodology and reported using PRISMA extension for scoping review checklist.

METHODS

A priori protocol was created with Peer Review of Electronic Search Strategies checklist and registered in the OSF registry. Databases including PubMed, CINAHL, ProQuest, Scopus, Science Direct, Web of Science and Google Scholar were searched. Published reports were reviewed against the eligibility criteria by performing Title and Abstract screening, followed by Full-text screening. The initial search yielded 1373 studies. Of these, 57 studies met the criteria for inclusion in this study.

RESULTS

The search revealed five general measures of cognitive mental workload and their variations. Only one customised measure specifically for medical-surgical nurses was found in the study. Identified measures were collated and categorised into a framework for conceptual clarity. NASA Task Load Index and its variations were the most popular subjective measure of cognitive mental workload in nursing. However, no measure or self-report scale customised for emergency nurses was identified.

PATIENT OR PUBLIC CONTRIBUTION

The findings of this scoping review can inform future research into the cognitive mental workload of nurses. The findings have implications for workplace health and safety for nurses and patients.

Remembering to Resume: A Randomized Trial Comparing Combined Interruption Management Training and Simulation-Based Education to Simulation-Based Education Alone

AIM

This study aimed to determine if purposeful presimulation interruption management training impacts cognitive load and successful completion of simulation objectives more than the experience alone.

BACKGROUND

Practicing nurses are frequently interrupted, increasing the risk for error and task time. Novices are particularly vulnerable to interruption consequences.

METHOD

A between-subjects design and block randomization of prelicensure baccalaureate nursing students ( n = 146) was used to compare group differences in cognitive load, use of interruption management strategies, and completion of simulation required elements. Potential relationships between outcomes and age, mindfulness, and experience were explored.

RESULTS

An analysis of covariance demonstrated significantly lower perceived mental demand for those receiving training. Older learners and those receiving training implemented more interruption management strategies.

CONCLUSION

Combining simulation-based education (SBE) with purposeful training enhances interruption management more than SBE alone. Frequent interruption training and SBE are recommended to enhance risk awareness.

Effects of different types of interference on nurses' working memory: An ERP study

AIM

To explore the effects of different types of interference on nurses' working memory, and the role of attention control.

DESIGN

A repeated measures design.

METHODS

A single-factor, four-level within-subjects design was adopted. Thirty-one nurses completed a delay-recognition task with four blocks in September 2020: Interrupting Stimulus (stimuli requiring attention), Distracting Stimulus (stimuli to-be-ignored), No Interference and Passively View. Behavioural responses of the participants and EEG data were recorded. MATLAB 21b and EEGLAB 21b were used for electroencephalogram data preprocessing and data extraction.

RESULTS

Firstly, when nursing information system was used as task material, the accuracy rate and false alarm rate of primary tasks under interruption condition was statistically significantly different with that of distraction and no interference condition. There is a statistically significant difference in electroencephalogram measurement between correct and wrong response under interruption. Secondly, the role of attention control was different under interruption and distraction. There was a statistically significant positive correlation between the average amplitude distraction attention control index and task accuracy, and statistically significant negative correlation between the latency interruption attention control index and the accuracy of working memory task.

CONCLUSIONS

There were different effects of interruptions and distractions on nurses' working memory and the role of attention control were also different. Measures can be designed according to these results to reduce the negative impact of interference on nurses, so as to improve work efficiency and reduce patient risk.

IMPACT

This study has implications for clinical nursing during human-computer interaction. Resumption of the speed of the target information after an interruption affected task performance. Therefore, interventions should be designed to reduce the time needed for nurses to extract task information after an interruption, such as providing key clues in the information system interface.

PATIENT OR PUBLIC CONTRIBUTION

Registered nurses participated in the study as subjects.

The levels and related factors of mental workload among nurses: A systematic review and meta-analysis

AIM

The aim was to determine the overall levels and related factors of mental workload assessed using the NASA-TLX tool among nurses.

BACKGROUND

Mental workload is a key element that affects nursing performance. However, there exists no review regarding mental workload assessed using the NASA-TLX tool, focusing on nurses.

DESIGN

A systematic review and meta-analysis.

DATA SOURCES

PubMed, MEDLINE, Web of Science, EMBASE, PsycINFO, Scopus, CINAHL, CNKI, CBM, Weipu and WanFang databases were searched from 1 January 1998 to 30 February 2022.

REVIEW METHODS

Following the PRISMA statement recommendations, review methods resulted in 31 quantitative studies retained for inclusion which were evaluated with the evaluation criteria for observational studies as recommended by the Agency for Healthcare Research and Quality. The data were pooled and a random-effects meta-analysis conducted.

RESULTS

Findings showed the pooled mental workload score was 65.24, and the pooled prevalence of high mental workload was 54%. Subgroup analysis indicated nurses in developing countries and emergency departments experienced higher mental workloads, and the mental workloads of front-line nurses increased significantly during the COVID-19 pandemic.

CONCLUSION

These findings highlight that nurses experience high mental workloads as assessed using the NASA-TLX tool and there is an urgent need to explore interventions to decrease their mental workloads.

Shift handover quality in Saudi critical care units: determinants from nurses' perspectives

BACKGROUND

Nurses' effective handover communication is vital for patient safety and quality of care. Few studies have empirically tested how certain factors influence the quality of handover in the Saudi context.

METHODS

A descriptive correlational design was used with a convenience sample of all nurses (N = 201) working in Saudi hospital CCUs in 2022. Demographics and handover quality instruments were used to collect the necessary data in addition to two open-ended questions that asked about perceived barriers and facilitators to handover. The analysis was conducted using descriptive statistics and regression analysis.

RESULTS

The majority of nurses reported good-quality handover. The regression analysis showed that staffing, cognitive capacity, the focus of attention, relationships, and safety climate factors contributed positively to the variance of handover quality. In contrast, intrusions, distractions, anxiety, time stress, and acute and chronic fatigue factors negatively affected the prediction of handover quality (p < 0.05). Nurses added types of shifts and languages as barriers to handover while emphasizing training and the use of standardized tools for handover as facilitators.

CONCLUSION AND RECOMMENDATIONS

Nursing handover is a multidimensional phenomenon. By understanding the determinants that contribute to or hinder handover quality, it is possible to develop targeted interventions aimed at improving communication and the quality of shift handover in CCUs. The current study's findings highlight the need for nurses to work in a more supportive environment, receive better training, and follow a standardized handover protocol. Additionally, nurse managers should pay more attention to nurses' well-being to control or mitigate the effect of psychological precursors on the quality of nurses' handover. Future research should investigate handover practices and outcomes on units that have both good and bad practice environments.

Development and Validation of a Nursing Work Interruption Scale

Work interruption disturbs nurses' flow of thinking, diminishes work efficiency, induces burnout, and causes errors that can threaten patients' lives. Therefore, it is important to identify the causes and measure the extent of work interruption. This study developed a self-report scale and established its validity and reliability for use in hospital settings. Through literature review and in-depth interviews with nurses, we identified two components and developed 25 preliminary items. These items were reviewed by nursing experts for content validity and pilot tested among 20 hospital nurses; subsequently, a 16-item preliminary instrument was finalized. A total of 359 questionnaires were included in the final analysis, and exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed. Two factors and 12 items were derived from two rounds of EFA, with a cumulative percentage of variance of 55.73%. Construct validity was established through CFA. The predictive validity and internal consistency reliability of the developed scale were also established. Thus, the 12-item Work Interruption Measurement Scale for Nurses comprising two domains (human and environmental factors) was developed. This scale can be useful in assessing work interruption experienced by nurses and for developing and assessing the effectiveness of interventions pertaining to nurses' work interruption.

Systematic review of interruptions in the emergency department work environment

OBJECTIVE

The purpose of this systematic review is to describe the operationalization of interruptions measurement and to synthesize the evidence on the causes and consequences of interruptions in the emergency department (ED) work environment.

METHODS

This systematic review of studies explores the causes and consequences of interruptions in the ED. Of 2836 abstract/titles screened, 137 full-text articles were reviewed, and 44 articles met inclusion criteria of measuring ED interruptions.

RESULTS

All articles reported primary data collection, and most were cohort studies (n = 30, 68%). Conceptual or operational definitions of interruptions were included in 27 articles. Direct observation was the most common approach. In half of the studies, quantitative measures of interruptions in the ED were descriptive only, without measurements of interruptions' consequences. Twenty-two studies evaluated consequences, including workload, delays, satisfaction, and errors. Overall, relationships between ED interruptions and their causes and consequences are primarily derived from direct observation within large academic hospitals using heterogeneous definitions. Collective strengths of interruptions research in the ED include structured methods of naturalistic observation and definitions of interruptions derived from concept analysis. Limitations are conflicting and complex evaluations of consequences attributed to interruptions, including the predominance of descriptive reports characterizing interruptions without direct measurements of consequences.

CONCLUSIONS

The use of standardized definitions and measurements in interruptions research could contribute to measuring the impact and influence of interruptions on clinicians' productivity and efficiency as well as patients' outcomes, and thus provide a basis for intervention research.

Interruption in the work of nursing professionals: conceptual analysis

OBJECTIVES

to analyze the concept of "interruption in the work of nursing professionals".

METHODS

conceptual study according to the method proposed by Walker and Avant through integrative literature review. The study searched the databases using the descriptors: "Attention", "Attention Bias", "Health Personnel", "Nurses", "Patient Safety" and "Medical Malpractices". The sample consisted of 36 studies.

RESULTS

the antecedents were alarms, answering phone calls, providing patient care, and lack of material/medicine. The defining attributes were pause, suspension, breakage, and intrusion. In relation to the consequences, the study highlighted the increase in frequency and severity of medication errors and change of focus.

FINAL CONSIDERATIONS

theconceptual analysis identified the attributes, antecedents, and consequences and allowed to build an operational definition for "interruption in the work of nursing professionals". It will contribute to the improvement of the work process and the creation of strategies that ensure safer care for the patient.

Degree of interruptions experienced by emergency department nurses and interruption related factors

AIMS

This study examined the degree of interruptions experienced by emergency department nurses and related factors.

METHODS

This study is a descriptive survey using standardized observation tools. A total of 23 nurses working in an emergency department participated in this study. Using a stopwatch over 120 h, the degree of interruptions was investigated by measuring start and end times of tasks and interruptions. Factors related to interruptions were classified as communication, telephone calls, medical device alarms, changes in patient condition, and other factors.

RESULTS

The frequency of interruptions in the emergency department was 6.4 times per hour, and its percentage was 9.1%. The time required for actual nursing tasks of "counseling and education," "safety," and "patient nursing management and information management" were increased significantly due to interruptions. A primary factor in interruptions was communication with patients, families, and nurses. The longest duration and the highest frequency of interruptions occurred during medication tasks.

CONCLUSIONS

Communication with patients, families, and nurses was the highest factor related to interruptions. Nurses may cause interruptions and be subjected to interruptions simultaneously. Therefore, nurses in the emergency department should work with caution not to cause interruptions.

Time from Pain Assessment to Pain Intervention

OBJECTIVE

The purpose of this study was to describe factors that influence nurses' time from pain assessment to intervention for acute postsurgical pain.

BACKGROUND

Nurses' time is a limited resource that must be optimized to manage patients' pain within budget constraints. Little is known about processes and activities nurses negotiate to manage pain.

METHODS

Human factors engineering and ethnography were used to quantify factors influencing time from pain assessment to intervention.

RESULTS

On the basis of 175.5 observation hours, nurses spent 11% of shifts (mean, 83 minutes) on pain care activities. Time from alert to intervention with PRN analgesics or biobehavioral strategies for 58 cases ranged from 0 to 48 minutes (mean, <11 minutes). Five factors influenced timeliness.

CONCLUSIONS

Nurses most efficiently managed postsurgical pain by giving analgesics ordered PRN on a scheduled basis. Nurse leaders can empower prompt responses to patients' pain through delegation, process improvements, real-time monitoring, and prescriber engagement.

Factors Influencing Nurses' Work Interruption in Wuhan Isolation Wards During the COVID-19 Pandemic

Background

Through January 2021, the novel coronavirus (COVID-19) continued to create significant pressure on medical staff who have worked to treat patients with the disease and control its spread. This study aimed to increase understanding of the situation and influencing factors of nurses’ work interruption in Wuhan’s isolation ward during the COVID-19 pandemic.

Material/Methods

A self-designed general situation questionnaire and work interruption questionnaire were used to survey 160 nurses from Beijing, Chongqing, and Jilin who worked during the COVID-19 pandemic in Wuhan in March 2020. The questionnaire could only be answered once by each nurse via a WeChat account. The submitted answers were verified by 2 researchers.

Results

The results showed that the rate of interruption of work among nurses in the isolation ward was 25%, and the rate of nurses experiencing a negative experience was 96.9%. The results of univariate analysis showed that the following factors were related to the work interruption of the nurses in the isolation ward (all P<0.05): emergency public incident training; emergency public incident treatment experience; knowledge of COVID-19 pneumonia; hours worked per shift in the quarantine area; and negative physiologic experience. Logistic regression analysis showed that negative experience, hours worked per shift, and emergency public incident training were the independent factors influencing work interruption among nurses in the isolation wards.

Conclusions

The incidence of interruption of work among nurses in the isolation ward was 25%. Negative experiences, long working hours per shift, and lack of emergency public incident training made the nurses more prone to work interruption.

Nursing interruptions in emergency room in China: An observational study

AIM

To analyse the frequency and core elements of nursing work interruptions in Chinese emergency nursing settings.

BACKGROUND

Little is known about nursing interruptions, which affect the quality of services in Chinese emergency nursing setting.

METHOD(S)

A cross-sectional observational study was conducted in three units of an emergency department in a Chinese tertiary hospital. Participants comprised 60 nurses. Data were collected using a questionnaire developed by the researchers specifically for this study.

RESULTS

In total, 25,965 min of work was observed and 2333 interruptions were identified. Most interruptions were from patients, their families and nurses. Therapeutic nursing and patient observation and documentation were the most frequently interrupted procedures. Most interruptions were negative, and a majority of the nurses immediately responded to interruptions. Significant differences existed in the overall distribution of the core elements among the three nursing units.

CONCLUSIONS

The frequency of emergency nursing interruptions was moderate. Most interruptions tend to lead to negative treatment outcomes for patients.

IMPLICATIONS FOR NURSING MANAGEMENT

Emergency nursing managers should recognize the importance of interruptions, understand work situations better and develop ways to reduce the incidence of interruptions. Thus, nursing risks can be avoided by reducing the adverse outcomes caused by work interruptions.

Changes in Fatigue Levels and Sleep Measures of Hospital Nurses During Two 12-Hour Work Shifts

OBJECTIVE

The aims of this study were to explore nurses' fatigue levels and sleep measures during two 12-hour consecutive day shifts and examine the relationships between nurses' fatigue levels within shifts and their previous-night sleep characteristics.

BACKGROUND

Monitoring changes in fatigue and sleep is important to enable effective fatigue management.

METHODS

This was a descriptive, repeated-measures study. Data were collected using surveys and actigraphy 4 times during each consecutive shift (7:00 am-7:30 pm).

RESULTS

General fatigue levels started trending up 4 hours after the start of work; highest levels were reported at 7:30 pm. Fatigue levels accumulated across consecutive shifts. Subjective sleep quality was higher the night before the 2nd shift than the night before the 1st shift. Nurses' poor sleep the night before a shift was related to increased fatigue levels during the next shift.

CONCLUSION

It is important to consider when fatigue management interventions will be most effective and to consider previous-night's sleep when monitoring fatigue.

A pilot study of non-routine events in gynecological surgery: Type, impact, and effect

OBJECTIVE

Quantifying non-routine events (NREs) assists with identify underlying sociotechnical factors that could lead to adverse events. NREs are considered any event that is unusual or atypical during surgical procedures. This study aimed to use prospective observations to characterize the occurrence of non-routine events in gynecological surgeries.

METHODS

Observational data were collected prospectively within one surgical gynecology department over a five month period. Researchers captured NREs in real time using a validated tablet PC-based tool according to the NRE type, impact, whom was affected, and duration. Researchers also noted what surgical approach (i.e. open, laparoscopic, robotic) was used.

RESULTS

Across 45 surgical cases, 554 non-routine events (M = 12.31 NREs per case, SD = 9.81) were identified. The majority of non-routine events were external interruptions (40.3%), teamwork (26.7%), or equipment (21.3%). The circulating nurse was most frequently affected by NREs (43.2%) followed by the entire surgical team (13.7%). There was no statistically significant difference in non-routine events based on surgical approach.

CONCLUSION

Non-routine events are prevalent in the gynecological surgical setting. Identifying the sociotechnical factors that influence non-routine events are important in determining interventions that will combat the associated risks. Interventions focusing on teamwork, managing external interruptions, and coordinating equipment may have the greatest impact to reduce or eliminate NREs in gynecological surgeries.
