Impact of Interruptions, Distractions, and Cognitive Load on Procedure Failures and Medication Administration Errors

Can humanoid robots be used as a cognitive offloading tool?

Cognitive load occurs when the demands of a task surpass the available processing capacity, straining mental resources and potentially impairing performance efficiency, such as increasing the number of errors in a task. Owing to its ubiquity in real-world scenarios, the existence of offloading strategies to reduce cognitive load is not new to experts and nonexperts, and many of these strategies involve technology (e.g., using Calendar Apps to remember scheduled events). Surprisingly, little is known about the potential use of humanoid robots for cognitive offloading. We will examine studies assessing the influence of humanoid robots on cognitive tasks requiring the resolution of cognitive conflict to determine whether their presence facilitates or hinders cognitive performance. Our analysis focuses on standardized cognitive conflict paradigms, as these effectively simulate real-life conflict scenarios (i.e., everyday challenges in focusing on the task and ignoring distractions). In these studies, robots were involved by either participating in the tasks, providing social cues, or observing human performance. By identifying contexts where humanoid robots support cognitive offloading and where they may undermine it, this work contributes to a deeper understanding of cognitive processes in human-robot interaction (HRI) and informs the design of interventions aimed at improving task performance and well-being in professional HRI settings.

A pilot study of performance enhancement coaching for newly appointed urology registrars

OBJECTIVES

To assess the feasibility of performance enhancement coaching (PEC) for newly appointed Urology registrars (ST3s), specifically: whether the concept appealed, and which areas beyond technical skills acquisition were felt to be most relevant or useful.

SUBJECTS AND METHODS

All delegates on the Urology Bootcamp 2023 were invited to take part in an online survey before and after a 2-hour PEC workshop, collecting: basic demographic data, performance challenges, and the important aspects to include in, and consider with, a coaching programme. The workshop was delivered by a surgeon with a professional coaching qualification, to groups of four delegates at a time over 4 days. Ten pre-defined areas were offered during the session.

RESULTS

On a scale of 1 (poor) to 10 (excellent), the 62 participants' overall health was reported as a median of 8/10 (physical) and 7/10 (mental). Anxiety during performance was the most common concern (63%) and was accompanied by a tremor in 55%. The next most popular concerns, with 19% of responses each, were: sleep, insufficient operative skill or expertise, and worry about relationships with trainers. The commonest topics discussed were 'the inner critic' (100%), 'autonomic modulation' (69%), 'not working, well' (13%) and 'optimising study' (6%). Seventy-seven per cent were unaware of PEC for practising surgeons. All respondents felt that they would benefit from PEC to some extent (80% ≥8/10 where 10/10 was 'very useful'), ideally at the ST3 level. Sixty-two percent of respondents said there should be a fee for trainees, whereas 38% thought it should be free and paid for by their training authorities.

CONCLUSION

The concept of PEC is acceptable to ST3 Urology trainees, with particular interest in techniques to mitigate negative self-talk and autonomic modulation techniques. Existing barriers to coaching for the surgical community would need to be addressed in designing an acceptable coaching programme.

Understanding the Role of Cognitive Load in Paramedical Contexts: A Systematic Review

OBJECTIVES

Cognitive load refers to the working memory resources required during a task. When the load is too high or too low this has implications for an individual's task performance. In the context of paramedicine and emergency medical services (EMS) broadly, high cognitive load could potentially put patient and personnel safety at risk. This systematic review aimed to determine the current understanding of the role of cognitive load in paramedical contexts.

METHODS

To do this, five databases were searched (Elsevier Embase, ProQuest Psychology, CINAHL, Ovid Medline, and Ovid PsychINFO) using synonyms of cognitive load and paramedical contexts. Included articles were full text, peer reviewed empirical research, with a focus on cognitive load and EMS work. Two reviewers screened titles, abstracts, and full text using a traffic light system against the inclusion and exclusion criteria. The quality of evidence was assessed using the GRADE framework. This study was registered on PROSPERO (CRD42022384246). No funding was received for this research.

RESULTS

The searches identified 73 unique articles and after title/abstract and full text screening, 25 articles were included in the final review. Synthesis of the research revealed 10 categories of findings in the area. These are clinical performance, cognitive processes, emotional responses, physical expenditure, physiological responses, equipment and ergonomics, expertise and experience, multiple loads, cognitive load measures, and task complexity.

CONCLUSIONS

From these findings it was determined that there is agreement in terms of what factors influence cognitive load in paramedical contexts, such as cognitive processes, task complexity, physical expenditure, level of experience, multiple types of loads, and the use of equipment. Cognitive load influences clinical task performance and has a bi-directional relationship with emotion. However, the literature is mixed regarding physiological responses to cognitive load, and how they are best measured. These findings highlight potential intervention points where cognitive load can be managed or reduced to improve working conditions for EMS clinicians and safety for their patients.

An Interruption Management Education Bundle: Feasibility Testing With Nursing Students

BACKGROUND

Interruptions and distractions are pervasive in health care settings, increase risks for errors, and decrease task efficiency. Researchers recommend the use of strategies to mitigate their negative effects.

PURPOSE

The purpose was to assess the feasibility and acceptability of (1) an education bundle that included an interruption management strategy and (2) simulated scenarios with embedded interruptions and distractions.

METHODS

Nineteen undergraduate nursing students participated in this repeated-measures, multimethods feasibility study. Data on interruption management behaviors were collected across 3 timepoints via direct observation of individual-simulated medication administration. Participants' perceptions of the education bundle were explored via semistructured interviews.

RESULTS

Participants described the simulated scenarios as realistic and interruption management strategy as easy to use and remember. Participants voiced increased confidence in handling interruptions after learning the strategy. The strategy averaged 4 seconds to apply.

CONCLUSIONS

Findings support the feasibility and acceptability of the bundle and need for studies to investigate the impact of the strategy on errors and task durations.

Attention Among Health Care Professionals : A Scoping Review

BACKGROUND

The concept of attention can provide insight into the needs of clinicians and how health systems design can impact patient care quality and medical errors.

PURPOSE

To conduct a scoping review to 1) identify and characterize literature relevant to clinician attention; 2) compile metrics used to measure attention; and 3) create a framework of key concepts.

DATA SOURCES

Cumulated Index to Nursing and Allied Health Literature (CINAHL), Medline (PubMed), and Embase (Ovid) from 2001 to 26 February 2024.

STUDY SELECTION

English-language studies addressing health care worker attention in patient care. At least dual review and data abstraction.

DATA EXTRACTION

Article information, health care professional studied, practice environment, study design and intent, factor type related to attention, and metrics of attention used.

DATA SYNTHESIS

Of 6448 screened articles, 585 met inclusion criteria. Most studies were descriptive (n = 469) versus investigational (n = 116). More studies focused on barriers to attention (n = 387; 342 descriptive and 45 investigational) versus facilitators to improving attention (n = 198; 112 descriptive and 86 investigational). We developed a framework, grouping studies into 6 categories: 1) definitions of attention, 2) the clinical environment and its effect on attention, 3) personal factors affecting attention, 4) relationships between interventions or factors that affect attention and patient outcomes, 5) the effect of clinical alarms and alarm fatigue on attention, and 6) health information technology's effect on attention. Eighty-two metrics were used to measure attention.

LIMITATIONS

Does not synthesize answers to specific questions. Quality of studies was not assessed.

CONCLUSION

This overview may be a resource for researchers, quality improvement experts, and health system leaders to improve clinical environments. Future systematic reviews may synthesize evidence on metrics to measure attention and on the effectiveness of barriers or facilitators related to attention.

Sleep deprivation and medication administration errors in registered nurses-A scoping review

AIM

To explore whether sleep deprivation contributes to medication errors in registered nurses (RNs).

BACKGROUND

Sleep deprivation is a potential issue for RNs, particularly those who work shifts. Sleep deprivation has been found to have a negative impact on numerous cognitive processes. Nurses administer several medications to patients a day, potentially while sleep deprived-anecdotal reports suggest that this could result in an increased risk of error occurring.

DESIGN

A scoping review was conducted using the Prisma-ScR extension framework to explore what is known about the effect of RNs' sleep deprivation on medication administration errors.

METHODS

A search of databases generated 171 results. When inclusion and exclusion criteria were applied, 18 empirical studies were analysed. Studies included retrospective analysis of errors, surveys of perceptions of causes and observational studies.

RESULTS

Data indicated that RNs consider fatigue, which may be caused by sleep deprivation, to be a contributing factor to medication errors. The search only identified three observer studies, which provided conflicting results as to whether lack of sleep contributes to the error rate. Of the numerous tools used to measure sleep, the Pittsburgh Sleep Quality Index was the most frequently used.

CONCLUSION

Although RNs anecdotally consider a lack of sleep potentially contributes to medication errors, there is insufficient research to provide robust evidence to confirm this assumption.

NO PATIENT OR PUBLIC CONTRIBUTIONS

Patient or public contributions were not required for this scoping review.

RELEVANCE TO CLINICAL PRACTICE

Sleep deprivation is a potential issue for nurses, especially those who work shifts. Poor sleep impacts cognitive processes that potentially could increase errors. Nurses should be aware of the impact sleep may have on patient safety.

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.

Exploring social media adoption by nurses for nursing practice in rural Volta, Ghana

AIM

The purpose of the study was to inquire into social media adoption by nurses for nursing practice.

DESIGN

An exploratory descriptive qualitative design was employed in understanding social media adoption for nursing care among nurses.

METHOD

A purposive sampling technique was employed to recruit 12 participants for the study. A semi-structured interview guide was used to conduct in-depth interviews which were audiotaped, transcribed verbatim, coded and analysed. Thematic analysis was used to analyse the data with NVivo 12.

RESULTS

The findings revealed nurses found social media to be useful for the dissemination, and reception of information, professional development and enhanced referral networks. Apart from its usefulness, participants believe that it is easy to navigate its apps, clear and understandable to use and does not involve much mental effort hence their favourable attitude towards use. Some participants also believe that inaccurate information, privacy and confidentiality concerns, distraction and addiction were some potential risks that are associated with its usage in nursing practice. Due to this, some participants developed a negative attitude towards its usage.

PATIENT OR PUBLIC CONTRIBUTION

Twelve nurses actively participated in the study.

How do medication errors occur in the nursing communication process? Investigating the relationship between error types and error factors

BACKGROUND

Human error types and error factors are two important elements of error analysis. Understanding the relationship between them can contribute to new case analyses, the tendency of error occurrence statistics, error factor identification, and prevention of error recurrence.

OBJECTIVE

To provide evidence and guidance for the prevention and improvement of medication communication errors by quantitatively exploring the relationship between error types and error factors.

METHODS

Data were collected on self-reported errors in the medication administration process by nurses in all departments of three cooperative medical institutions, and an error sheet of specified style was adopted. Error types were determined by the systematic human error reduction and prediction approach method and human cognition processes. Error factors were extracted using the root cause analysis combined with Berlo's communication model, and the relationship between error types and error factors was quantitatively studied using the partial least-squares regression method.

RESULTS

After a one-by-one analysis of 303 error cases, the communication errors occurring in the nursing medication process could be explained by six error types and 12 error factors. In addition, 20 correlation patterns between the error types and error factors were quantitatively obtained, and their path coefficient distributions ranged from 0.088 to 0.467.

CONCLUSION

The results of this study may provide reference to understand errors and establish countermeasures from the statistics of error occurrence trends, extract error factors related to error types and determine key error factors.

A Novel Use of Bar Code Medication Administration Data to Assess Nurse Staffing and Workload

OBJECTIVE

The aim of the study is to introduce an innovative use of bar code medication administration (BCMA) data, medication pass analysis, that allows for the examination of nurse staffing and workload using data generated during regular nursing workflow.

METHODS

Using 1 year (October 1, 2014-September 30, 2015) of BCMA data for 11 acute care units in one Veterans Affairs Medical Center, we determined the peak time for scheduled medications and included medications scheduled for and administered within 2 hours of that time in analyses. We established for each staff member their daily peak-time medication pass characteristics (number of patients, number of peak-time scheduled medications, duration, start time), generated unit-level descriptive statistics, examined staffing trends, and estimated linear mixed-effects models of duration and start time.

RESULTS

As the most frequent (39.7%) scheduled medication time, 9:00 was the peak-time medication pass; 98.3% of patients (87.3% of patient-days) had a 9:00 medication. Use of nursing roles and number of patients per staff varied across units and over time. Number of patients, number of medications, and unit-level factors explained significant variability in registered nurse (RN) medication pass duration (conditional R2  = 0.237; marginal R2  = 0.199; intraclass correlation = 0.05). On average, an RN and a licensed practical nurse (LPN) with four patients, each with six medications, would be expected to take 70 and 74 minutes, respectively, to complete the medication pass. On a unit with median 10 patients per LPN, the median duration (127 minutes) represents untimely medication administration on more than half of staff days. With each additional patient assigned to a nurse, average start time was earlier by 4.2 minutes for RNs and 1.4 minutes for LPNs.

CONCLUSION

Medication pass analysis of BCMA data can provide health systems a means for assessing variations in staffing, workload, and nursing practice using data generated during routine patient care activities.

Patient handoffs among general surgery residents in Saudi Arabia: a cross-sectional study

BACKGROUND

Communication failure is a common cause of adverse events. An essential element of communication among health care providers is patient handoff. Patient handoff is defined as a practice whereby a health care provider transfers a patient's care information to another health care provider to ensure the patient's safety and continuity of care. To explore this practice, we assessed patient handoffs among general surgery residents in Saudi Arabia.

METHODS

A cross-sectional survey was conducted with individuals in accredited general surgery residency programs in Saudi Arabia between 2020 and 2021.

RESULTS

Participants comprised 118 general surgery residents: 66 (57.3%) were female; 67 (72.8%) did not receive any formal training on patient handoff; and 35 (38.8%) reported that they were sometimes interrupted during the patient handoff process. The most common reason for such interruptions was medical personnel paging. Furthermore, 60 (68.1%) general surgery residents stated that these interruptions led to a decreased quality of effective communication, 39 (44.3%) believed it led to decreased quality of patient care, 63 (71.5%) believed it led to the loss of some information related to patient handoff, and 16 (18.1%) believed it led to patient harm. Finally, 31 (34.4%) general surgery residents believed that the existing handoff system at their institutions neither adequately protected the patients' safety nor allowed for continuity of care, and 51 (68%) reported that their institution did not have a standardized protocol for the verbal patient handoff process. There was a higher proportion of patients with minor harm among residents who did not, rarely or sometimes received verbal or written hand off instructions compare to those who did so always or most of the time (67% vs. 49%, respectively).

CONCLUSION

The patient handoff process among general surgery residents in Saudi Arabia is subjective and is not standardized, and if not addressed, may lead to patient harm. Standardizing this process is paramount to improve patient safety.

Concepts and metrics of clinician attention: a scoping review protocol

INTRODUCTION

There is growing emphasis on the importance of both the cognitive and behavioural phenomenon of attention for clinicians engaged in patient care. Aspects of attention such as cognitive load, distraction and task switching have been studied in various settings with different methodologies. Using the protocol described here, we aim to systematically review the medical literature in order to map the concept of attention and to synthesise diverse concepts and methods under the broader category of research focused on 'attention'.

METHODS AND ANALYSIS

Following the methodology described by the Joanna Briggs Institute and Arksey and O'Malley, our scoping review conducts an iterative search of Cumulative Index of Nursing and Allied Health Literature (CINAHL), Medline (PubMed) and EMBASE (Ovid). An initial limited search based on key concepts and terminology will generate relevant articles which in turn will be mined for additional keywords and index terms to guide a formal literature search. Our multidisciplinary team will extract data into a matrix, including a small random sample of the same studies (to ensure concordance), and present the results in a descriptive narrative format.

ETHICS AND DISSEMINATION

As a secondary analysis, our study does not require ethics approval, and we will ensure that included studies have appropriate approval. We anticipate results will identify diverse ways of conceptualising clinician attention and will provide a foundation for developing additional metrics and study methods to optimise attention in the clinical environment. We will disseminate results through journals and conferences and coordinate with colleagues doing work in adjacent fields.

Selecting intervention content to target barriers and enablers of recognition and response to deteriorating patients: an online nominal group study

Background

Patients who deteriorate in hospital wards without appropriate recognition and/or response are at risk of increased morbidity and mortality. Track-and-trigger tools have been implemented internationally prompting healthcare practitioners (typically nursing staff) to recognise physiological changes (e.g. changes in blood pressure, heart rate) consistent with patient deterioration, and then to contact a practitioner with expertise in management of acute/critical illness. Despite some evidence these tools improve patient outcomes, their translation into clinical practice is inconsistent internationally. To drive greater guideline adherence in the use of the National Early Warning Score tool (a track-and-trigger tool used widely in the United Kingdom and parts of Europe), a theoretically informed implementation intervention was developed (targeting nursing staff) using the Theoretical Domains Framework (TDF) version 2 and a taxonomy of Behaviour Change Techniques (BCTs).

Methods

A three-stage process was followed: 1. TDF domains representing important barriers and enablers to target behaviours derived from earlier published empirical work were mapped to appropriate BCTs; 2. BCTs were shortlisted using consensus approaches within the research team; 3. shortlisted BCTs were presented to relevant stakeholders in two online group discussions where nominal group techniques were applied. Nominal group participants were healthcare leaders, senior clinicians, and ward-based nursing staff. Stakeholders individually generated concrete strategies for operationalising shortlisted BCTs (‘applications’) and privately ranked them according to acceptability and feasibility. Ranking data were used to drive decision-making about intervention content.

Results

Fifty BCTs (mapped in stage 1) were shortlisted to 14 (stage 2) and presented to stakeholders in nominal groups (stage 3) alongside example applications. Informed by ranking data from nominal groups, the intervention was populated with 12 BCTs that will be delivered face-to-face, to individuals and groups of nursing staff, through 18 applications.

Conclusions

A description of a theory-based behaviour change intervention is reported, populated with BCTs and applications generated and/or prioritised by stakeholders using replicable consensus methods. The feasibility of the proposed intervention should be tested in a clinical setting and the content of the intervention elaborated further to permit replication and evaluation.

Engaging Nursing Students in Quality Improvement: Teaching Safe Medication Administration

BACKGROUND

Safety and reduction of errors during medication administration is a prominent focus in nursing and nursing education. Developing simulated medication administration experiences that include opportunities for nursing students to manage interruptions in a realistic environment can help improved critical thinking and reasoning for safe administration practices.

METHOD

Sophomore nursing students voluntarily participated in a quality improvement project examining nursing management of interruptions during medication administration. Students observed medication administration activities for episodes of interruptions and conducted surveys in a real-time format that encouraged decision-making dialogue.

RESULTS

After the project, student learning outcomes included improved identification of interruptions, prioritization, critical reasoning skills, and development of management techniques for better safety.

CONCLUSION

Incorporating real-world experiences that allow nursing students to identify and manage interruptions during medication administration foster development of critical thinking and interruption management techniques. [J Nurs Educ. 2022;61(5):268-271.].

Unexpected Learning Opportunities for Nursing Students

ABSTRACT

Restrictions on groups and public gatherings during the COVID-19 pandemic have limited in-person learning experiences for nursing students. But the crisis has also led to unanticipated opportunities. In this article, we describe how participation in vaccination clinics at our university offered students occasions for experiential learning that aren't normally part of nursing education. Volunteering at these clinics allowed our students to practice important skills while participating in efforts to help mitigate the spread of the virus.

Pathways and factors that influence time to definitive trauma care for injured children in New South Wales, Australia

BACKGROUND

Timely definitive paediatric trauma care influences patient and parental physical and emotional outcomes. New South Wales (NSW) covers a large geographical area with all three NSW paediatric trauma centres (PTC) located in two approximated major cities, meaning it is inevitable that some injured children receive initial treatment locally and then require transfer. Little is known about the factors that then impact timely arrival of injured children to definitive care.

METHODS

This included children admitted between July 2015 and September 2016, <16 years with an injury severity (ISS) ≥9; or requiring intensive care admission; or deceased following injury. Children were identified through the three PTCs, NSW Trauma Registry and NSW Medical Retrieval Registry.

RESULTS

There were 593 children admitted following injury and 46% required transfer to a PTC. There was no significant difference in age, ISS, ICU admission or head injury (AIS >2) between transferred and directly transported cohorts. There were significant differences in mechanism of injury between the two groups (χ²(9) = 45.9, p < 0.001). The median (IQR) time to book a transfer from arrival at the referring facility, was 146.5 (86-238) minutes. Time from injury to arrival at the PTC more than doubled for children transferred, with significant and unwarranted variability between transporting agencies resulting in unwarranted delays to surgical intervention. For example, time spent at the referring facility by Aeromedical Retrieval Service was less than half that of the Newborn & paediatric Emergency Transport Service [53 (IQR:47-61) vs 115 (84-155) minutes (p <0.001)].

CONCLUSION

Clinicians caring for paediatric trauma patients in facilities outside trauma centres require the capability and opportunity to identify and notify early those requiring transfer for ongoing management. The provision of a streamlined referral and transfer process for all paediatric trauma patients requiring treatment in NSW PTCs would reduce the burden on the referring facility, reduce variation amongst transport providers and improve time to definitive care.

Predicting inpatient pharmacy order interventions using provider action data

Objective

The widespread deployment of electronic health records (EHRs) has introduced new sources of error and inefficiencies to the process of ordering medications in the hospital setting. Existing work identifies orders that require pharmacy intervention by comparing them to a patient’s medical records. In this work, we develop a machine learning model for identifying medication orders requiring intervention using only provider behavior and other contextual features that may reflect these new sources of inefficiencies.

Materials and Methods

Data on providers’ actions in the EHR system and pharmacy orders were collected over a 2-week period in a major metropolitan hospital system. A classification model was then built to identify orders requiring pharmacist intervention. We tune the model to the context in which it would be deployed and evaluate global and local feature importance.

Results

The resultant model had an area under the receiver-operator characteristic curve of 0.91 and an area under the precision-recall curve of 0.44.

Conclusions

Providers’ actions can serve as useful predictors in identifying medication orders that require pharmacy intervention. Careful model tuning for the clinical context in which the model is deployed can help to create an effective tool for improving health outcomes without using sensitive patient data.

Usability and Effectiveness of Immersive Virtual Grocery Shopping for Assessing Cognitive Fatigue in Healthy Controls: Protocol for a Randomized Controlled Trial

BACKGROUND

Cognitive fatigue (CF) is a human response to stimulation and stress and is a common comorbidity in many medical conditions that can result in serious consequences; however, studying CF under controlled conditions is difficult. Immersive virtual reality provides an experimental environment that enables the precise measurement of the response of an individual to complex stimuli in a controlled environment.

OBJECTIVE

We aim to examine the development of an immersive virtual shopping experience to measure subjective and objective indicators of CF induced by instrumental activities of daily living.

METHODS

We will recruit 84 healthy participants (aged 18-75 years) for a 2-phase study. Phase 1 is a user experience study for testing the software functionality, user interface, and realism of the virtual shopping environment. Phase 2 uses a 3-arm randomized controlled trial to determine the effect that the immersive environment has on fatigue. Participants will be randomized into 1 of 3 conditions exploring fatigue response during a typical human activity (grocery shopping). The level of cognitive and emotional challenges will change during each activity. The primary outcome of phase 1 is the experience of user interface difficulties. The primary outcome of phase 2 is self-reported CF. The core secondary phase 2 outcomes include subjective cognitive load, change in task performance behavior, and eye tracking. Phase 2 uses within-subject repeated measures analysis of variance to compare pre- and postfatigue measures under 3 conditions (control, cognitive challenge, and emotional challenge).

RESULTS

This study was approved by the scientific review committee of the National Institute of Nursing Research and was identified as an exempt study by the institutional review board of the National Institutes of Health. Data collection will begin in spring 2021.

CONCLUSIONS

Immersive virtual reality may be a useful research platform for simulating the induction of CF associated with the cognitive and emotional challenges of instrumental activities of daily living.

Overloaded and at Work: Investigating the Effect of Cognitive Workload on Assembly Task Performance

OBJECTIVE

This study investigates the effect of cognitive overload on assembly task performance and muscle activity.

BACKGROUND

Understanding an operator's cognitive workload is an important component in assessing human-machine interaction. However, little evidence is available on the effect that cognitive overload has on task performance and muscle activity when completing manufacturing tasks.

METHOD

Twenty-two volunteers completed an assembly task while performing a secondary cognitive task with increasing levels of demand (n-back). Performance in the assembly task (completion times, accuracy), muscle activity recorded as integrated electromyography (EMG), and self-reported workload were measured.

RESULTS

Results show that the increasing cognitive demand imposed by the n-back task resulted in impaired assembly task performance, overall greater muscle activity, and higher self-reported workload.Relative to the control condition, performing the 2-back task resulted in longer assembly task completion times (+10 s on average) and greater integrated EMG for flexor carpi ulnaris, triceps brachii, biceps brachii, anterior deltoid, and pectoralis major.

CONCLUSION

This study demonstrates that working under high cognitive load not only results in greater muscle activity, but also affects assembly task completion times, which may have a direct effect on manufacturing cycle times.

APPLICATION

Results are applicable to the assessment of the effects of high cognitive workload in manufacturing.

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.

Healthcare personnel's working conditions in relation to risk behaviours for organism transmission: A mixed-methods study

AIMS AND OBJECTIVES

To investigate healthcare personnel's working conditions in relation to risk behaviours for organism transmission.

BACKGROUND

Healthcare personnel's behaviour is often influenced by working conditions that in turn can impact the development of healthcare-associated infections. Observational studies are scarce, and further understanding of working conditions in relation to behaviour is essential for the benefit of the healthcare personnel and the safety of the patients.

DESIGN

A mixed-methods convergent design.

METHODS

Data were collected during 104 h of observation at eight hospital units. All 79 observed healthcare personnel were interviewed. Structured interviews covering aspects of working conditions were performed with the respective first-line manager. The qualitative and quantitative data were collected concurrently and given equal priority. Data were analysed separately and then merged. The study follows the GRAMMS guidelines for reporting mixed-methods research.

RESULTS

Regardless of measurable and perceived working conditions, risk behaviours frequently occurred especially missed hand disinfection. Healthcare personnel described staffing levels, patient-level workload, physical factors and interruptions as important conditions that influence infection prevention behaviours. The statistical analyses confirmed that interruptions increase the frequency of risk behaviours. Significantly higher frequencies of risk behaviours also occurred in activities where healthcare personnel worked together, which in the interviews was described as a consequence of caring for high-need patients.

CONCLUSIONS

These mixed-methods findings illustrate that healthcare personnel's perceptions do not always correspond to the observed results since risk behaviours frequently occurred regardless of the observed and perceived working conditions. Facilitating the possibility for healthcare personnel to work undisturbed when needed is essential for their benefit and for patient safety.

RELEVANCE FOR CLINICAL PRACTICE

The results can be used to enlighten healthcare personnel and managers and when designing future infection prevention work.

The Influence of Nurses' Characteristics on Medication Administration Errors: An Integrative Review

Background

Medication administration errors (MAEs) are a frequent cause of morbidity and mortality in acute care settings and can result in a prolonged hospital stay. The WHO estimated that medication errors cost up to $42 billion globally per a year. Therefore, MAEs was among the most common medical errors to occur in acute care settings. Studies of medication error usually focus on system factors, thus creating a gap between what researchers know about the causes of MAEs, and what frontline nurses actually do in the clinical setting. The purpose of this review is to fill a gap in the existing literature by focusing on the relationship between nurses' characteristics and MAEs.

Methods

Online databases were accessed, including CINAHL, PsycINFO, PubMed, Scopus, and Google Scholar from 2007-2020 period. This review was guided by the methods described by Whittemore and Knafl. Studies that addressed the occurrence of medication errors based on RN demographics were included in this review. The included studies were reviewed and analyzed by the two authors.

Results

Of the 1141 publications retrieved, 19 studies met inclusion criteria. The result provided strong evidence that nurses' level of education, length of experience, and attendance at training courses, are directly associated with the occurrence of MAEs. There is weak evidence of MAEs being influenced by the age and gender of nurses. Other nurse characteristics, such as cognitive load, frustration with technology, negligence, lack of attentiveness, and nurse ethnicity, are not adequately examined across the reviewed studies necessitates further research.

Conclusion

Focusing on nurses' characteristics might facilitate other researchers to suggest appropriate interventions that may reduce the incidence of MAEs. Interventional studies may provide convincing evidence as to whether one variable has a causal effect on another variable, and control the influence of confounding variables to enhance the generalizability of the findings.

"I'm not doing what I should be doing as a midwife": An ethnographic exploration of central fetal monitoring and perceptions of clinical safety

BACKGROUND

Central fetal monitoring systems transmit cardiotocograph data to a central site in a maternity service. Despite a paucity of evidence of safety, the installation of central fetal monitoring systems is common.

AIM

This qualitative research sought to explore whether, and how, clinicians modified their clinical safety related behaviours following the introduction of a central monitoring system.

METHODS

An Institutional Ethnographic enquiry was conducted at an Australian hospital where a central fetal monitoring system had been installed in 2016. Informants (n=50) were midwifery and obstetric staff. Data collection consisted of interviews and observations that were analysed to understand whether and how clinicians modified their clinical safety related behaviours.

FINDINGS

The introduction of the central monitoring system was associated with clinical decision making without complete clinical information. Midwives' work was disrupted. Higher levels of anxiety were described for midwives and birthing women. Midwives reported higher rates of intervention in response to the visibility of the cardiotocograph at the central monitoring station. Midwives described a shift in focus away from the birthing woman towards documenting in the central monitoring system.

DISCUSSION

The introduction of central fetal monitoring prompted new behaviours among midwifery and obstetric staff that may potentially undermine clinical safety.

CONCLUSION

This research raises concerns that central fetal monitoring systems may not promote safe intrapartum care. We argue that research examining the safety of central fetal monitoring systems is required.

Nurses' Perceptions of Workload Burden in Pediatric Critical Care

BACKGROUND

Quantifying nurses' perceptions of workload burden when managing critically ill patients is essential for designing interventions to ease nurses' workday.

OBJECTIVES

To explore pediatric intensive care unit (PICU) nurses' perceptions of their workload when caring for critically ill patients and managing protocolized therapies.

METHODS

This study was embedded in a multicenter randomized clinical trial where participants were assigned to receive either lower-target or higher-target glucose control. Nurses from 35 participating PICUs completed a baseline survey containing questions about their perceptions of PICU workload in general. They completed an intervention survey after caring for a study patient. Two workload measurement instruments, the Subjective Workload Assessment Technique (SWAT) and the National Aeronautics and Space Administration-Task Load Index (NASA-TLX), were embedded in these surveys.

RESULTS

Baseline surveys were completed by 1476 PICU nurses, predominantly female with a bachelor's degree and a median (interquartile range) of 6 (3-11) years of nursing experience and 4 (2-9) years of PICU experience. Most nurses (65%) rated time burden as the most important component of their workload, followed by cognitive (22%) or psychological stress (13%) burden. Work performance was selected most often as contributing to workload, followed by cognitive demand, time pressure, effort, and physical demand. Intervention surveys were completed by 73% of enrolled participants (505 of 693). Nurses managing the lower glucose target group reported higher levels of workload burden as measured by the SWAT (P = .002) and NASA-TLX (P < .001).

CONCLUSIONS

This study describes the workload burden perceived by PICU nurses when managing critically ill patients in general and when managing protocolized therapies.

Characteristics of recovery from near misses in primary health care nursing: A Prospective descriptive study

AIM

To describe the frequency and types of near misses and the recovery strategies employed by nurses in primary health care.

BACKGROUND

Insufficient data are available on the role of nurses in near miss events and related factors in primary health care.

METHOD

A prospective descriptive study was carried out at one Urban Primary Health Care Centre, within the Málaga-Guadalhorce Health District (Malaga, Spain), from January to December 2018. Four of the ten nurses volunteered to take part.

RESULTS

The nurses recovered 185 near misses, prevailing administrative or communication-related errors, followed by medication-related errors. No near misses were reported on the centre's anonymous error information platform.

CONCLUSIONS

A significant number of near misses occurred which could have been avoided with better communication among health care personnel. A striking finding is the failure to inform the health centre, which suggests that improvements in safety culture are needed.

IMPLICATIONS FOR NURSING MANAGEMENT

It is the responsibility and the duty of nursing management to be aware of the characteristics and frequency of near misses in primary health care, to implement strategies for improvement and to foster a culture in which the necessary information on actual or potential errors is supplied.

Using Qualitative Methods to Explore Communication Practices in the Context of Patient Care Rounds on General Care Units

BACKGROUND

Poor communication between physicians and nurses is a significant contributor to adverse events for hospitalized patients. Overcoming communication difficulties requires examining communication practices to better understand some of the factors that affect the nurse-physician communication process.

OBJECTIVE

To develop a more detailed understanding of communication practices between nurses and physicians on general care units. We focused on patient care rounds as an important activity in the care delivery process for communication.

DESIGN

Qualitative study design PARTICIPANTS: A total of 163 physicians, registered nurses, and nurse practitioners who worked on pre-specified general care units in each of four hospitals in the Midwest.

APPROACH

On each unit, data collection consisted of 2 weeks of observing and shadowing clinicians during rounds and at other times, as well as asking clinicians questions about rounds and communication during interviews and focus groups. A directed content analysis approach was used to code and analyze the data.

KEY RESULTS

Workflow differences contributed to organizational complexity, affecting rounds and subsequently communication practices, both across and within provider types. Nurse and patient participation during rounds appeared to reduce interruptions and hence cognitive load for physicians and nurses. Physicians adopted certain behaviors within the social context to improve communication, such as socializing and building relationships with the nurses, which contributed to nurse participation in rounds. When rapport was lacking, some nurses felt uncomfortable joining physicians during rounds unless they were explicitly invited.

CONCLUSIONS

Improving communication requires bringing attention to three contextual dimensions of communication: organizational complexity, cognitive load, and the social context. Initiatives that seek to improve communication may be more successful if they acknowledge the complexity of communication and the context in which it occurs.

Reducing interruptions during medication preparation and administration

PURPOSE

According to literature, interruptions during drug administration lead to a significant proportion of medication errors. Evidence on the effectiveness of interventions to reduce interruption is still limited. The purpose of this paper is to explore main reasons for interruptions during drug administration rounds in a geriatric ward of an Italian secondary hospital and test the effectiveness of a combined intervention.

DESIGN/METHODOLOGY/APPROACH

This is a pre and post-intervention observational study based on direct observation. All nurse staff (24) participated to the study that lead to observe a total of 44 drug dispensing rounds with 945 drugs administered to 491 patients in T0 and 994 drugs to 506 patients in T1.

FINDINGS

A significant reduction of raw number of interruptions (mean per round from 17.31 in T0 to 9.09 in T1, p<0.01), interruptions/patient rate (from 0.78 in T0 to 0.40 in T1, p<0.01) and interruptions/drugs rate (from 0.44 in T0 to 0.22 in T1, p<0.01) were observed. Needs for further improvements were elicited (e.g. a greater involvement of support staff).

PRACTICAL IMPLICATIONS

Nurse staff should be adequately trained on the risks related to interruptions during drug administration since routine activity is at high risk of distractions due to its repetitive and skill-based nature.

ORIGINALITY/VALUE

A strong involvement of both MB and leadership, together with the frontline staff, helped to raise staff motivation and guide a bottom-up approach, able to identify tailored interventions and serve concurrently as training instrument tool.

Interruptions in Health Care: Assessing Their Connection With Error and Patient Harm

OBJECTIVE

We address the problem of how researchers investigate the actual or potential causal connection between interruptions and medical errors, and whether interventions might reduce the potential for harm.

BACKGROUND

It is widely assumed that interruptions lead to errors and patient harm. However, many reviewers and authors have commented that there is not strong evidence for a causal connection.

METHOD

We introduce a framework of criteria for assessing how strongly evidence implies causality: the so-called Bradford Hill criteria. We then examine four key "metanarratives" of research into interruptions in health care-applied cognitive psychology, epidemiology, quality improvement, and cognitive systems engineering-and assess how each tradition has addressed the causal connection between interruptions and error.

RESULTS

Outcomes of applying the Bradford Hill criteria are that the applied cognitive psychology and epidemiology metanarratives address the causal connection relatively directly, whereas the quality improvement metanarrative merely assumes causality, and the cognitive systems engineering metanarrative either implicitly or explicitly questions the feasibility of finding a direct causal connection with harm.

CONCLUSION

The Bradford Hill criteria are useful for evaluating the existing literature on the relationship between interruptions in health care, clinical errors, and the potential for patient harm. In the future, more attention is needed to the issue of why interruptions usually do not lead to harm, and the implications for how we approach patient safety.

Association of medication administration errors with interruption among nurses in public sector tertiary care hospitals

Objectives:

To determine the association of medication administration errors with interruption among nurses working at public sector tertiary care hospitals in Karachi, Pakistan.

Methods:

An analytical cross-sectional study was accomplished at two public sector healthcare facilities Civil Hospital, and Dow University Hospital, Karachi. The study was carried out from October 2017 to July 2018 over a period of 10 months. The sample was calculated by using OpenEpi version 3.0. By taking 56.4% of medication administration errors, 5% margin of error and 95% confidence level. The calculated sample size was 204 of both genders. The subjects both male and female nurses having a valid license from Pakistan Nursing Council and one year of clinical experience were enrolled in the study. The subjects were approached by using non-probability purposive sampling method. Validated and adapted questionnaire utilized to gather the data. Data was entered and analyzed by using SPSS version 21.0.

Results:

In this study, total 204 nurses were included, almost half (52%) of them were male. Majority of (82.3%) study participants had age between 25-35 years old. There were total 716 medications given by 204 nurses. Out of these, 295 (41.2%) were antibiotics, other common medications were acid-suppressive, analgesic and antiemetic 14.5%, 15.9% and 11.2% respectively. Among all 716 medications, 644 (89.9%) were given intravenously whereas only 6.7% drugs given orally. A significant association has been found between medication administration errors and interruption like talking with other health care personnel, patients or attendant queries, phone calls (p-value=<0.001). Nearly 91% of the study nurses who were interrupted during medication committed medication errors.

Conclusion:

It is concluded that there is a significant association between medication administration errors with interruption among nurses.

Nurses' perceptions of high-alert medication administration safety: A qualitative descriptive study

AIMS

The aim of this study was to determine nurses' perceptions of supports and barriers to high-alert medication (HAM) administration safety.

DESIGN

A qualitative descriptive design was used.

METHODS

Eighteen acute care nurses were interviewed about HAM administration practices. Registered nurses (RNs) working with acutely ill adults in two hospitals participated in one-on-one interviews from July-September, 2017. Content analysis was conducted for data analysis.

RESULTS

Three themes contributed to HAM administration safety: Organizational Culture of Safety, Collaboration, and RN Competence and Engagement. Error factors included distractions, workload and acuity. Work arounds bypassing bar code scanning and independent double check procedures were common. Findings highlighted the importance of intra- and interprofessional collaboration, nurse engagement and incorporating the patient in HAM safety.

CONCLUSIONS

Current HAM safety strategies are not consistently used. An organizational culture that supports collaboration, education on safe HAM practices, pragmatic HAM policies and enhanced technology are recommended to prevent HAM errors.

IMPACT

Hospitals incorporating these findings could reduce HAM errors. Research on nurse engagement, intra- and interprofessional collaboration and inclusion of patients in HAM safety strategies is needed.

Cognitive load theory for training health professionals in the workplace: A BEME review of studies among diverse professions: BEME Guide No. 53

AIM

Cognitive load theory (CLT) is of increasing interest to health professions education researchers. CLT has intuitive applicability to workplace settings, yet how CLT should inform teaching, learning, and research in health professions workplaces is unclear.

METHOD

To map the existing literature, we performed a scoping review of studies involving cognitive load, mental effort and/or mental workload in professional workplace settings within and outside of the health professions. We included actual and simulated workplaces and workplace tasks.

RESULT

Searching eight databases, we identified 4571 citations, of which 116 met inclusion criteria. Studies were most often quantitative. Methods to measure cognitive load included psychometric, physiologic, and secondary task approaches. Few covariates of cognitive load or performance were studied. Overall cognitive load and intrinsic load were consistently negatively associated with the level of experience and performance. Studies consistently found distractions and other aspects of workplace environments as contributing to extraneous load. Studies outside the health professions documented similar findings to those within the health professions, supporting relevance of CLT to workplace learning.

CONCLUSION

The authors discuss implications for workplace teaching, curricular design, learning environment, and metacognition. To advance workplace learning, the authors suggest future CLT research should address higher-level questions and integrate other learning frameworks.

Foram considerados significativos os resultados com valores de p < 0,05 e o índice de confiança estabelecido foi de 95 %.Resultados: em ambos os hospitais verificou-se um perfil majoritariamente de técnicos de enfermagem (H1 = 100 %; H2 = 94,4 %), do sexo feminino (H1 = 75,0 %; H2 = 88,1 %), com idade superior aos 30 anos (H1 = 75,0 %; H2 = 61,0 %). Foram observadas 899 doses no Hospital 1 e Hospital 2, que resultaram em 921 e 648 erros respectivamente, dos quais 464 (53,6 %) no Hospital 1 e 118 (24,4 %) no Hospital 2 estiveram diretamente relacionados à presença de interrupções no trabalho. Cada dose observada sofreu aproximadamente 1,7 erro e percebeu-se uma frequência de aproximadamente 26 (H1) e 16,2 (H2) erros por hora. Conclusões: verifica-se uma forte associação entre as interrupções no trabalho da equipe de enfermagem e os erros de medicação nas unidades de internação estudadas, caracterizando as interrupções como importante fator de risco.

To err is human: medication patient safety in aged care, a case study

Purpose

The purpose of this paper is to explore an identified medication error using a root cause analysis and a clinical case study.

Design/methodology/approach

In this paper the authors explore a medication error through the completion of a root cause analysis and case study in an aged care facility.

Findings

Research indicates that medication errors are highly prevalent in aged care and 40 per cent of nursing home patients are regularly receiving at least one potentially inappropriate medicine (Hamilton, 2009; Raban et al., 2014; Shehab et al., 2016). Insufficient patient information, delays in continuing medications, poor communication, the absence of an up-to-date medication chart and missed or significantly delayed doses are all linked to medication errors (Dwyer et al., 2014). Strategies to improve medication management across hospitalisation to medication administration include utilisation of a computerised medication prescription and management system, pharmacist review, direct communication of discharge medication documentation to community pharmacists and staff education and support (Dolanski et al., 2013).

Originality/value

Discussion of the factors impacting on medication errors within aged care facilities may explain why they are prevalent and serve as a basis for strategies to improve medication management and facilitate further research on this topic.

Interruptions During Senior Nurse Handover in the Intensive Care Unit: A Quality Improvement Study

BACKGROUND

Interruptions during handover may compromise continuity of care and patient safety.

LOCAL PROBLEM

Interruptions occur frequently during handovers in the intensive care unit.

METHODS

A quality improvement study was undertaken to improve nursing team leader handover processes. The frequency, source, and reason interruptions occurred were recorded before and after a handover intervention.

INTERVENTIONS

The intervention involved relocating handover from the desk to bedside and using a printed version of an evidence-based electronic minimum data set. These strategies were supported by education, champions, reminders, and audit and feedback.

RESULTS

Forty handovers were audiotaped before, and 49 were observed 3 months following the intervention. Sixty-four interruptions occurred before and 52 after the intervention, but this difference was not statistically significant. Team leaders were frequently interrupted by nurses discussing personal or work-specific matters before and after the intervention.

CONCLUSIONS

Further work is required to reduce interruptions that do not benefit patient care.

Direct Observation of Medication Errors in Critical Care Setting: A Systematic Review

Medication errors continue to be an issue for the critically ill and are costly to both patients and health care facilities. This article reviews published research about these errors and reports results of observational studies. The types of errors, incidence, and root causes have been considered along with adverse consequences. The implications for bedside practice as a result of this review are fairly straightforward. Medication errors are happening at an alarming rate in the critical care environment, and these errors are preventable. It is imperative that all personnel respect and follow established guidelines and procedural safeguards to ensure flawless drug delivery to patients.

Work Interruption Experienced by Nurses during Medication Administration Process and Associated Factors, Northwest Ethiopia

BACKGROUND

During medication administration process, including preparation, administration, and documentation, there is high proportion of work interruption that results in medication administration errors that consequently affect the safety of patients. Thus, the main purpose of this study was to assess the prevalence of work interruption and associated factors during medication administration process.

METHODS

A prospective, observation-based, cross-sectional study was conducted on 278 nurses. Structure observational sheet was utilized to collect data. EPI Info version 3.5.3 and SPSS version 20 software were utilized for data entry and analysis, respectively. Binary and multivariable logistic regression were fitted to identify the associated factors using an odds ratio and 95% CI.

RESULTS

The incidence of work interruption was found to be 1,152 during medication administration process. Of this, 579 (50.3%) were major/severe work interruptions. Unit of work, day of the week, professional experience, perceived severity of work interruption, source/initiator of interruption, and secondary tasks were factors significantly associated with major work interruptions at p < 0.05.

CONCLUSION

In this study, more than half of work interruption was major/severe. Thus, the authors suggest raising the awareness of nurses regarding the severity of work interruptions, with special attention to those who have lower work experience, sources of interruption, and secondary tasks by assigning additional nurses who manage secondary tasks and supportive supervision.
