Unreported clinical deterioration in emergency department patients: A point prevalence study

Wearable wireless continuous vital signs monitoring on the general ward

PURPOSE OF REVIEW

Wearable wireless sensors for continuous vital signs monitoring (CVSM) offer the potential for early identification of patient deterioration, especially in low-intensity care settings like general wards. This study aims to review advances in wearable CVSM - with a focus on the general ward - highlighting the technological characteristics of CVSM systems, user perspectives and impact on patient outcomes by exploring recent evidence.

RECENT FINDINGS

The accuracy of wearable sensors measuring vital signs exhibits variability, especially notable in ambulatory patients within hospital settings, and standard validation protocols are lacking. Usability of CMVS systems is critical for nurses and patients, highlighting the need for easy-to-use wearable sensors, and expansion of the number of measured vital signs. Current software systems lack integration with hospital IT infrastructures and workflow automation. Imperative enhancements involve nurse-friendly, less intrusive alarm strategies, and advanced decision support systems. Despite observed reductions in ICU admissions and Rapid Response Team calls, the impact on patient outcomes lacks robust statistical significance.

SUMMARY

Widespread implementation of CVSM systems on the general ward and potentially outside the hospital seems inevitable. Despite the theoretical benefits of CVSM systems in improving clinical outcomes, and supporting nursing care by optimizing clinical workflow efficiency, the demonstrated effects in clinical practice are mixed. This review highlights the existing challenges related to data quality, usability, implementation, integration, interpretation, and user perspectives, as well as the need for robust evidence to support their impact on patient outcomes, workflow and cost-effectiveness.

Impact of an emergency department rapid response system on inpatient clinical deterioration: A controlled pre-post study

AIM

To determine the impact implementation of Emergency Department Clinical Emergency Response System (EDCERS) on inpatient deterioration events and identify contributing causal factors.

METHODS

EDCERS was implemented in an Australian regional hospital, integrating a single parameter track and trigger criteria for escalation of care, and emergency, specialty and critical care clinician response to patient deterioration. In this controlled pre-post study, electronic medical records of patients who experienced a deterioration event (rapid response call, cardiac arrest or unplanned intensive care admission) on the ward within 72 h of admission from the emergency department (ED) were reviewed. Causal factors contributing to the deteriorating event were assessed using a validated human factors framework.

RESULTS

Implementation of EDCERS reduced the number of inpatient deterioration events within 72 h of emergency admission with failure or delayed response to ED patient deterioration as a causal factor. There was no change in the overall rate of inpatient deterioration events.

CONCLUSION

This study supports wider implementation of rapid response systems in the ED to improve management of deteriorating patients. Tailored implementation strategies should be used to achieve successful and sustainable uptake of ED rapid response systems and improve outcomes in deteriorating patients.

Missed nursing care in emergency departments: A scoping review

BACKGROUND

Patient safety is a global health priority. Errors of omission, such as missed nursing care in hospitals, are frequent and may lead to adverse events. Emergency departments (ED) are especially vulnerable to patient safety errors, and the significance missed nursing care has in this context is not as well known as in other contexts.

AIM

The aim of this scoping review was to summarize and disseminate research about missed nursing care in the context of EDs.

METHOD

A scoping review following the framework suggested by Arksey and O'Malley was used to (1) identify the research question; (2) identify relevant studies; (3) select studies; (4) chart the data; (5) collate, summarize, and report the results; and (6) consultation.

RESULTS

In total, 20 themes were derived from the 55 included studies. Missed or delayed assessments or other fundamental care were examples of missed nursing care characteristics. EDs not staffed or dimensioned in relation to the patient load were identified as a cause of missed nursing care in most included studies. Clinical deteriorations and medication errors were described in the included studies in relation to patient safety and quality of care deficiencies. Registered nurses also expressed that missed nursing care was undignified and unsafe.

CONCLUSION

The findings from this scoping review indicate that patients' fundamental needs are not met in the ED, mainly because of the patient load and how the ED is designed. According to registered nurses, missed nursing care is perceived as undignified and unsafe.

Predicting patient decompensation from continuous physiologic monitoring in the emergency department

Anticipation of clinical decompensation is essential for effective emergency and critical care. In this study, we develop a multimodal machine learning approach to predict the onset of new vital sign abnormalities (tachycardia, hypotension, hypoxia) in ED patients with normal initial vital signs. Our method combines standard triage data (vital signs, demographics, chief complaint) with features derived from a brief period of continuous physiologic monitoring, extracted via both conventional signal processing and transformer-based deep learning on ECG and PPG waveforms. We study 19,847 adult ED visits, divided into training (75%), validation (12.5%), and a chronologically sequential held-out test set (12.5%). The best-performing models use a combination of engineered and transformer-derived features, predicting in a 90-minute window new tachycardia with AUROC of 0.836 (95% CI, 0.800-0.870), new hypotension with AUROC 0.802 (95% CI, 0.747-0.856), and new hypoxia with AUROC 0.713 (95% CI, 0.680-0.745), in all cases significantly outperforming models using only standard triage data. Salient features include vital sign trends, PPG perfusion index, and ECG waveforms. This approach could improve the triage of apparently stable patients and be applied continuously for the prediction of near-term clinical deterioration.

Effective handovers on escalation of care for the deteriorating patient

Evidence suggests that improvements in clinical practice are required to ensure that deteriorating patients are rapidly identified and assessed in a systematic manner. The important step of escalating care involves a detailed handover to the most appropriate colleague so that interventions can be put in place to reverse or optimise the patient's condition. However, multiple issues can hinder this handover process, including a lack of confidence among nurses and suboptimal team dynamics or cultures. Using structured communication tools such as situation, background, assessment, recommendation (SBAR) can assist nurses in delivering a handover that results in the desired outcome. This article explains the steps involved in identifying, assessing and escalating the care of deteriorating patients, and describes the components of an effective handover.

Implementation evaluation of an evidence-based emergency nursing framework (HIRAID): study protocol for a step-wedge randomised control trial

INTRODUCTION

Poor patient assessment results in undetected clinical deterioration. Yet, there is no standardised assessment framework for >29 000 Australian emergency nurses. To reduce clinical variation and increase safety and quality of initial emergency nursing care, the evidence-based emergency nursing framework HIRAID (History, Identify Red flags, Assessment, Interventions, Diagnostics, communication and reassessment) was developed and piloted. This paper presents the rationale and protocol for a multicentre clinical trial of HIRAID.

METHODS AND ANALYSIS

Using an effectiveness-implementation hybrid design, the study incorporates a stepped-wedge cluster randomised controlled trial of HIRAID at 31 emergency departments (EDs) in New South Wales, Victoria and Queensland. The primary outcomes are incidence of inpatient deterioration related to ED care, time to analgesia, patient satisfaction and medical satisfaction with nursing clinical handover (effectiveness). Strategies that optimise HIRAID uptake (implementation) and implementation fidelity will be determined to assess if HIRAID was implemented as intended at all sites.

ETHICS AND DISSEMINATION

Ethics has been approved for NSW sites through Greater Western Human Research Ethics Committee (2020/ETH02164), and for Victoria and Queensland sites through Royal Brisbane & Woman's Hospital Human Research Ethics Committee (2021/QRBW/80026). The final phase of the study will integrate the findings in a toolkit for national rollout. A dissemination, communications (variety of platforms) and upscaling strategy will be designed and actioned with the organisations that influence state and national level health policy and emergency nurse education, including the Australian Commission for Quality and Safety in Health Care. Scaling up of findings could be achieved by embedding HIRAID into national transition to nursing programmes, 'business as usual' ED training schedules and university curricula.

Understanding the use of the National Early Warning Score 2 in acute care settings: a realist review protocol

INTRODUCTION

Failure to recognise and respond to patient deterioration in an appropriate and timely manner has been highlighted as a global patient safety concern. Early Warning Scores (EWSs) using vital signs were introduced to address this concern, with the aim of getting the patient timely and appropriate treatment. The National Early Warning Score 2 (NEWS2) is in use across the NHS, and many other settings globally. While patient improvements have been shown, research has identified that the NEWS2 is not always used as intended. Therefore, this review will use a realist approach to understand what the mechanisms are that influence appropriate use (or not) of the NEWS2 in acute care settings, how, for whom and in which contexts. The findings will inform clinicians of what helps and/or hinders appropriate use of the NEWS2 in clinical practice, thus helping to facilitate successful implementation.

METHODS AND ANALYSIS

Our realist review will follow Pawson's iterative six step process: (1) Development of initial programme theory. (2) Searching the literature; an information scientist will develop, pilot and refine the search strategy. A systematic search will be completed, based on subject relevancy on the following databases: Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medline, Embase (OvidSP), Web of Science (Science Citation Index and Social Science Citation), Cochrane Database of Systematic Reviews, Joanna Briggs Institute, Ethos, Proquest Dissertations and Theses Global, and Google Scholar for documents dating from 1997 (date of the first published EWS) to present. To retrieve additional relevant data 'snowballing' (finding references and authors by hand, contacting authors, searching reference lists and citation-tracking using Google Scholar) will be used. Inclusion criteria include all documents (including grey literature) that relate to the use of EWSs/NEWS2 in the English language only. Documents set in the paediatric, maternity and primary care settings will be excluded. (3) Selecting documents and quality appraisal. (4) Extracting and organising the data. (5) Synthesising the data. (6) Disseminating the findings. We will recruit a group of stakeholders comprised of experienced clinicians who use the NEWS2 as part of their clinical practice to provide feedback throughout the review. Step 1 has already begun with the development of an initial programme theory. This initial programme theory presents how the NEWS2 is supposed to work (or not), it will now be developed, tested and refined.

ETHICS AND DISSEMINATION

Ethical approval is not required for this study as it is secondary research. Dissemination will include a peer-reviewed publication and conference presentations. Findings will also be amplified through social media platforms with user friendly summaries. Our stakeholder group will also contribute to dissemination of findings in their clinical areas and among existing networks.

Exploration and model development for emergency department waiting room nurse role: Synthesis of a three-phase sequential mixed methods study

BACKGROUND

To improve flow and care in waiting rooms, some emergency departments introduced a specific nursing role to care for this patient cohort with the aim of commencing interventions early, improving patient safety by reassessing and enhancing communication. The objective of the research was to explore to what extent does qualitative interviews and quantitative survey contribute to describing emergency department waiting room nurses, through integration and synthesis of findings from a multiphase mixed methods study.

METHODS

Multiphase mixed methods exploratory sequential design with integration of findings. Data integration occurred during the phases and when assimilating all findings.

FINDINGS

Experienced emergency nurses, preferably with graduate qualifications, who are autonomous practitioners with highly developed communication skills, clinical decision making and proficiency in assessment and monitoring are required to perform the role. The waiting room nurse provides patient-centered care and ensures safe, timely care is delivered to those in the waiting room. A standardised approach and high risk of exposure to occupational stressors need to be considered.

CONCLUSIONS

This mixed methods sequential design explored the waiting room nurse role from the perspective of emergency nurses generating new knowledge into the role. This advanced practice nursing role contributes to patient safety and delivery of patient centred care in the emergency department waiting room.

Systems for recognition and response to deteriorating emergency department patients: a scoping review

Background

Assessing and managing the risk of clinical deterioration is a cornerstone of emergency care, commencing at triage and continuing throughout the emergency department (ED) care. The aim of this scoping review was to assess the extent, range and nature of published research related to formal systems for recognising and responding to clinical deterioration in emergency department (ED) patients.

Materials and methods

We conducted a scoping review according to PRISMA-ScR guidelines. MEDLINE complete, CINAHL and Embase were searched on 07 April 2021 from their dates of inception. Human studies evaluating formal systems for recognising and responding to clinical deterioration occurring after triage that were published in English were included. Formal systems for recognising and responding to clinical deterioration were defined as: i) predefined patient assessment criteria for clinical deterioration (single trigger or aggregate score), and, or ii) a predefined, expected response should a patient fulfil the criteria for clinical deterioration. Studies of short stay units and observation wards; deterioration during the triage process; system or score development or validation; and systems requiring pathology test results were excluded. The following characteristics of each study were extracted: author(s), year, design, country, aims, population, system tested, outcomes examined, and major findings.

Results

After removal of duplicates, there were 2696 publications. Of these 33 studies representing 109,066 patients were included: all were observational studies. Twenty-two aggregate scoring systems were evaluated in 29 studies and three single trigger systems were evaluated in four studies. There were three major findings: i) few studies reported the use of systems for recognising and responding to clinical deterioration to improve care of patients whilst in the ED; ii) the systems for recognising clinical deterioration in ED patients were highly variable and iii) few studies reported on the ED response to patients identified as deteriorating.

Conclusion

There is a need to re-focus the research related to use of systems for recognition and response to deteriorating patients from predicting various post-ED events to their real-time use to improve patient safety during ED care.

The implementation of an emergency nursing framework (HIRAID) reduces patient deterioration: A multi-centre quasi-experimental study

INTRODUCTION

Timely recognition and treatment of acutely ill patients at appropriate levels of the health system are fundamental to the quality and safety of healthcare. This study determines if the implementation of an emergency nursing framework HIRAID (History, Identify Red flags, Assessment, Interventions, Diagnostics, communication and reassessment) improves patient safety.

METHODS

A quasi-experimental cohort study was conducted in two emergency departments in [Anonymised], Australia. HIRAID was implemented using a multi-pronged behaviour change intervention. Data of 920 patients (374 pre and 546 post) who deteriorated within 72-hours of ED departure were collected. Statistical tests were conducted as two-sided, with a 95% confidence interval to determine pre/post cohort association.

RESULTS

Patients in the post group had more comorbidities, but experienced less deterioration associated with care delivered in the ED (27% to 13%). There was a reduction in treatment delays [ 28.3% to 15.1%, p = 0.041, 95% CI (1.1%-25.3%)], and delay or failure to escalate care when abnormal vital signs were identified [20.2% to6.9%, p = 0.014, 95% CI (3.5%-23.1%)]. Isolated nursing-related causal factors decreased from 20 (21%) to 6 (8%).

CONCLUSIONS

Implementing a standardised emergency nursing framework is associated with a reduction in clinical deterioration related to emergency care.

Modifications to medical emergency team activation criteria and implications for patient safety: A point prevalence study

BACKGROUND

Medical emergency team (MET) activation criteria are sometimes modified to minimise unnecessary MET calls in patients who have chronic physiological derangements, have limitation of medical treatment orders in place, or have recently received treatment for clinical deterioration. However, the safety implications of modifying MET activation criteria are poorly understood.

OBJECTIVES

The aim of the study was to examine the safety of modifying MET activation criteria. Specifically, we aimed to examine the frequency and nature of modifications to MET activation criteria and compare characteristics and outcomes of patients with and without modifications to MET activation criteria.

METHODS

This was a point prevalence study using a retrospective medical record audit. Patients admitted to 14 wards on November 7, 2018, at two acute-care hospitals of one health service in Melbourne, Australia, were included (N = 430). Data were analysed using descriptive and inferential statistics. The main outcome measures included frequency and nature of modifications to MET activation criteria on a specified date, MET calls, intensive care unit admission, in-hospital cardiac arrest, and in-hospital death.

RESULTS

Amongst 430 inpatients, there were 30 modifications to MET activation criteria in 26 (6.0%) patients. All modifications were intended to trigger METs at more extreme levels of physiological derangement. Most modifications pertained to tachypnoea (26.7%; n = 8/30) and bradycardia (23.3%; n = 7/30). Patients with modifications were more likely to have documented physiological deterioration that fulfilled MET (47.8%, n = 11; p < 0.001) or pre-MET (87.0%, n = 20; p < 0.001) criteria in the preceding 24-h period than patients without modifications. Of patients with modifications, none were admitted to an intensive care unit, had a cardiac arrest, or died in the hospital. There were no differences in hospital length of stay or discharge destination between patients with and without modifications.

CONCLUSIONS

In this point prevalence study, modifications to MET activation criteria were infrequent and not associated with negative patient safety outcomes.

Assessment of patient safety challenges and electronic occurrence variance reporting (e-OVR) barriers facing physicians and nurses in the emergency department: a cross sectional study

BACKGROUND

The purpose of patient safety is to prevent harm occurring in the healthcare system. Patient safety is improved by the use of a reporting system in which healthcare workers can document and learn from incidents, and thus prevent potential medical errors. The present study aimed to determine patient safety challenges facing clinicians (physicians and nurses) in emergency medicine and to assess barriers to using e-OVR (electronic occurrence variance reporting).

METHODS

This cross-sectional study involved physicians and nurses in the emergency department (ED) at King Khalid University Hospital (KKUH) in Riyadh, Saudi Arabia. Using convenience sampling, a self-administered questionnaire was distributed to 294 clinicians working in the ED. The questionnaire consisted of items pertaining to patient safety and e-OVR usability. Data were analyzed using frequencies, means, and percentages, and the chi-square test was used for comparison.

RESULTS

A total of 197 participants completed the questionnaire (67% response rate) of which 48 were physicians (24%) and 149 nurses (76%). Only 39% of participants thought that there was enough staff to handle work in the ED. Roughly half (48%) of participants spoke up when something negatively affected patient safety, and 61% admitted that they sometimes missed important patient care information during shift changes. Two-thirds (66%) of the participants reported experiencing violence. Regarding e-OVR, 31% of participants found reporting to be time consuming. Most (85%) participants agreed that e-OVR training regarding knowledge and skills was sufficient. Physicians reported lower knowledge levels regarding how to access (46%) and how to use (44%) e-OVR compared to nurses (98 and 95%, respectively; p < 0.01). Less than a quarter of the staff did not receive timely feedback after reporting. Regarding overall satisfaction with e-OVR, only 25% of physicians were generally satisfied compared to nearly half (52%) of nurses.

CONCLUSION

Although patient safety is well emphasized in clinical practice, especially in the ED, many factors hinder patient safety. More awareness is needed to eliminate violence and to emphasize the needs of additional staff in the ED. Electronic reporting and documentation of incidents should be well supported by continuous staff training, help, and feedback.

Translation of evidence into policy to improve clinical practice: the development of an emergency department rapid response system

BACKGROUND

Undetected clinical deterioration is a major cause of high mortality events in Emergency Department (ED) patients. Yet, there is no known model to guide the recognition and response to clinical deterioration in the ED, integrating internal and external resources.

METHODS

An integrative review was firstly conducted to identify the critical components of recognising and responding to clinical deterioration in the ED. Components identified from the review were analysed by clinical experts and informed the development of an ED Clinical Emergency Response System (EDCERS).

RESULTS

Twenty four eligible studies were included in the review. Eight core components were identified: 1) vital sign monitoring; 2) track and trigger system; 3) communication plan; 4) response time; 5) emergency nurse response; 6) emergency physician response; 7) critical care team response; and 8) specialty team response. These components informed the development of the EDCERS protocol, integrating responses from staff internal and external to the ED.

CONCLUSIONS

EDCERS was based on the best available evidence and considered the cultural context of care. Future research is needed to determine the useability and impact of EDCERS on patient and health outcomes.

The prevalence and management of deteriorating patients in an Australian emergency department

BACKGROUND

Complex human and system factors impact the effectiveness of Rapid Response Systems (RRS). Emergency Department (ED) specific RRS are relatively new and the factors associated with their effectiveness are largely unknown. This study describes the period prevalence of deterioration and characteristics of care for deteriorating patients in an Australia ED and examine relationships between system factors and escalation of care.

METHODS

A retrospective medical record audit of all patients presenting to an Australian ED in two weeks.

RESULTS

Period prevalence of deterioration was 10.08% (n=269). Failure to escalate care occurred in nearly half (n=52, 47.3%) of the patients requiring a response (n=110). Appropriate escalation practices were associated with where the patient was being cared for (p=0.01), and the competence level of the person documenting deterioration (p=0.005). Intermediate competence level nurses were nine times more likely to escalate care than novices and experts (p=0.005). While there was variance in escalation practice related to system factors, these associations were not statistically significant.

CONCLUSION

The safety of deteriorating ED patients may be improved by informing care based on the escalation practices of staff with intermediate ED experience and competence levels.

Predicting cardiac arrest in the emergency department

In-hospital cardiac arrest remains a leading cause of death: roughly 300,000 in-hospital cardiac arrests occur each year in the United States, ≈10% of which occur in the emergency department. ED-based cardiac arrest may represent a subset of in-hospital cardiac arrest with a higher proportion of reversible etiologies and a higher potential for neurologically intact survival. Patients presenting to the ED have become increasingly complex, have a high burden of critical illness, and face crowded departments with thinly stretched resources. As a result, patients in the ED are vulnerable to unrecognized clinical deterioration that may lead to ED-based cardiac arrest. Efforts to identify patients who may progress to ED-based cardiac arrest have traditionally been approached through identification of critically ill patients at triage and the identification of patients who unexpectedly deteriorate during their stay in the ED. Interventions to facilitate appropriate triage and resource allocation, as well as earlier identification of patients at risk of deterioration in the ED, could potentially allow for both prevention of cardiac arrest and optimization of outcomes from ED-based cardiac arrest. This review will discuss the epidemiology of ED-based cardiac arrest, as well as commonly used approaches to predict ED-based cardiac arrest and highlight areas that require further research to improve outcomes for this population.

Emergency nurses' perceptions of their role in responding to escalations of care for clinical deterioration

BACKGROUND

Clinical leadership is fundamental to patient safety. The Emergency Department (ED) nurse-in-charge is a key leadership role; however, few studies have explored the management of clinical deterioration from the ED nurse-in-charge perspective. The aim of this study was to explore ED nurses-in-charge' perceptions of their role in responding to episodes of escalation of care for clinical deterioration of ED patients.

METHODS

A prospective exploratory descriptive design was used to address the study aims. The study was conducted in an urban ED in Melbourne, Australia. Senior emergency nurses who fulfilled the role of being in charge of the ED were invited to participate. In-depth semi-structured interviews were conducted between December 2015 and March 2016. Interview transcripts were analysed using thematic analysis.

RESULTS

Two major themes, each with two subthemes were identified. The first major theme of Clinical Risk Management comprised sub-themes of Clinical Skills and Confidence. The second major theme of Resource Management comprised sub-themes of Human Resource Management and Logistical Resource Management.

CONCLUSIONS

Strong collaboration, logistical and clinical risk management roles were perceived as fundamental to the nurse-in-charge's capacity to respond to escalations of care for clinical deterioration within in a complex team environment such as the ED.

The implementation and usability of HIRAID, a structured approach to emergency nursing assessment

BACKGROUND

Emergency nurses are responsible for the initial assessment, management and safety of critically ill patients. HIRAID, an evidence-informed emergency nursing assessment framework, is known to improve emergency nursing patient-assessment in the simulated environment however has not been evaluated in the clinical setting.

METHODS

A pre-post design was used to assess the usability and impact of HIRAID on emergency nurses self-efficacy in the emergency department (ED). Nursing and medical staff from three Australian EDs were surveyed. Descriptive and optimal pooled sample t-tests statistics were conducted.

RESULTS

One hundred and two emergency nurses completed the pre-intervention self-efficacy survey and 63 completed the post-intervention self-efficacy and satisfaction survey. Forty-two and 17 medical officers completed the pre- and post-intervention satisfaction surveys, respectively. Nursing staff self-efficacy levels were unchanged pre- and post-HIRAID implementation (Mean (SD): 8.8 (0.21) vs. 8.7 (0.20)) as was medical staff satisfaction (Mean (SD):7.5 (1.43) vs. 7.8 (1.07)), although there was a trend towards improved communication.

CONCLUSION

The HIRAID structured approach to patient assessment is acceptable, feasible, practical and appropriate for use in the clinical environment. Further research will demonstrate the direct effects of HIRAID on clinical performance.

To identify the factors that influence the recognizing and responding to adult patient deterioration in acute hospitals

AIMS

To identify factors that influence recognition and response to adult patient deterioration in acute hospitals.

DESIGN

A mixed-studies systematic review.

DATA SOURCES

CINAHL, Medline, and Web of Science were searched for relevant literature published between 2007 - 2018.

REVIEW METHODS

Studies were critically appraised, data extracted and thematically analysed.

RESULTS

Thirteen papers met the inclusion criteria. Three main themes were identified: (a) Knowledge and understanding of clinical deterioration; (b) Organizational factors; managing deterioration and staffing levels; and (c) Communication; inter-professional relationships and professional-patient communication.

CONCLUSION

Despite national guidelines, the review findings suggest that the recognition and response to adult patient deterioration in acute hospital settings is sub-optimal. A multitude of factors influencing the recognition and response to adult patient deterioration emerged from the findings.

IMPACT

Patients are receiving sub-optimal care due to failure in recognizing and responding to patient deterioration in an appropriate and timely manner. Nurses lack knowledge and understanding of deterioration. Organizational factors contribute to inadequate care and communication among professionals was highlighted as challenging. The factors that influence the recognizing and responding to patient deterioration in acute hospitals are multi-faceted, however this review highlights immediate recommendations for professionals in the acute care setting.

Patient acceptability of wearable vital sign monitoring technologies in the acute care setting: A systematic review

AIMS AND OBJECTIVES

To examine patient acceptability of wearable vital sign monitoring devices in the acute setting.

BACKGROUND

Wearable vital sign monitoring devices may improve patient safety, yet hospital patients' acceptability of these devices is largely unreported.

DESIGN

A systematic review.

METHODS

Cumulative Index to Nursing and Allied Health Literature Complete, MEDLINE Complete and EMBASE were searched, supplemented by reference list hand searching. Studies were included if they involved adult hospital patients (≥18 years), a wearable monitoring device capable of assessing ≥1 vital sign, and measured patient acceptability, satisfaction or experience of wearing the device. No date restrictions were enforced. Quality assessments of quantitative and qualitative studies were undertaken using the Downs and Black Checklist for Measuring Study Quality and the Critical Appraisal Skills Programme Qualitative Research Checklist, respectively. Meta-analyses were not possible given data heterogeneity and low research quality. Reporting adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and a Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist was completed.

RESULTS

Of the 427 studies screened, seven observational studies met the inclusion criteria. Six studies were of low quality and one was of high quality. In two studies, patient satisfaction was investigated. In the remaining studies, patient experience, patient opinions and experience, patient perceptions and experience, device acceptability, and patient comfort and concerns were investigated. In four studies, patients were mostly accepting of the wearable devices, reporting positive experiences and satisfaction relating to their use. In three studies, findings were mixed.

CONCLUSION

There is limited high-quality research examining patient acceptability of wearable vital sign monitoring devices as an a priori focus in the acute setting. Further understanding of patient perspectives of these devices is required to inform their continued use and development.

RELEVANCE TO CLINICAL PRACTICE

The provision of patient-centred nursing care is contingent on understanding patients' preferences, including their acceptability of technology use.

A profile of the waiting room nurse in emergency departments: An online survey of Australian nurses exploring implementation and perceptions

BACKGROUND

In response to increasing waiting times, adverse patient outcomes and patient dissatisfaction, some emergency departments introduced a Waiting Room Nurse role. Despite implementation into routine practice, there remains limited formal evaluation of the role.

AIM

To explore the implementation of a Waiting Room Nurse role in Australian emergency departments and emergency nurses' perceptions.

METHODS

Survey design. A 40-item survey was developed, piloted and then distributed to members of a professional College for online completion. Responses for closed-ended and open-ended items were reported using frequencies or proportions, and quantitative content analysis, respectively.

RESULTS

Respondents (n = 197) reported that 51 emergency departments allocated a Waiting Room Nurse, with varying hours of operation. Five key areas of responsibility were: patient care, patient safety, escalation of care, triage and communication. Role variations were identified in experience, preparation and supporting policies. Challenges, including workload and personal safety issues, were reported.

CONCLUSIONS

The role was perceived as vital, especially at times of high demand, in ensuring that patients were safe to wait, detecting deterioration and escalating care as needed. Communication and therapeutic relationships were key to effective performance. Challenges identified had clear implications for the welfare of nurses performing the role.

Clinical deterioration: A concept analysis

AIMS AND OBJECTIVES

To present a concept analysis of clinical deterioration and introduce an operational definition.

BACKGROUND

Hospitalised patients who endure cardiopulmonary arrest and unplanned intensive care unit admissions often exhibit physiological signs preceding these events. Clinical deterioration not promptly recognised can result in increased patient morbidity and mortality. A barrier to recognising and responding to clinical deterioration stems from practice variations among healthcare clinicians.

DESIGN

Concept analysis.

METHODS

Eight-step method of concept analysis proposed by Walker and Avant.

RESULTS

Defining attributes include dynamic state, decompensation and objective and subjective determination. Antecedents identified include clinical state, susceptibility, pathogenesis and adverse event. Increased mortality, resuscitation, implementation of higher level of care and prolonged hospital admission were the consequences identified. Defining attributes, antecedents and consequences identified led to an operational definition of clinical deterioration as a dynamic state experienced by a patient compromising hemodynamic stability, marked by physiological decompensation accompanied by subjective or objective findings.

CONCLUSIONS

Clinical deterioration is a key contributor to inpatient mortality, and its recognition is often underpinned by contextual factors and practice variances. Variation in the uniformity of the concept of clinical deterioration causes a gap in knowledge and necessitated clarification of this phenomenon for nursing research and practice.

RELEVANCE TO CLINICAL PRACTICE

Identifying and intervening on clinical deterioration plays a vital role in the inpatient setting demonstrated by the dynamic nature of a patients' condition during hospitalisation. It is anticipated that this concept analysis on clinical deterioration will contribute to further identification of clinically modifiable risk factors and accompanying interventions to prevent clinical deterioration in the inpatient setting.

Implementation evaluation and refinement of an intervention to improve blunt chest injury management-A mixed-methods study

Aims and objectives

To investigate uptake of a Chest Injury Protocol (ChIP), examine factors influencing its implementation and identify interventions for promoting its use.

Background

Failure to treat blunt chest injuries in a timely manner with sufficient analgesia, physiotherapy and respiratory support, can lead to complications such as pneumonia and respiratory failure and/or death.

Design

This is a mixed‐methods implementation evaluation study.

Methods

Two methods were used: (i) identification and review of the characteristics of all patients eligible for the ChIP protocol, and (ii) survey of hospital staff opinions mapped to the Theoretical Domains Framework (TDF) to identify barriers and facilitators to implementation. The characteristics and treatment received between the groups were compared using the chi‐square test or Fischer's exact test for proportions, and the Mann–Whitney U‐test for continuous data. Quantitative survey data were analysed using descriptive statistics. Qualitative data were coded in NVivo 10 using a coding guide based on the TDF and Behaviour Change Wheel (BCW). Identification of interventions to change target behaviours was sourced from the Behaviour Change Technique Taxonomy Version 1 in consultation with stakeholders.

Results

Only 68.4% of eligible patients received ChIP. Fifteen facilitators and 10 barriers were identified to influence the implementation of ChIP in the clinical setting. These themes were mapped to 10 of the 14 TDF domains and corresponded with all nine intervention functions in the BCW. Seven of these intervention functions were selected to address the target behaviours and a multi‐faceted relaunch of the revised protocol developed. Following re‐launch, uptake increased to 91%.

Conclusions

This study demonstrated how the BCW may be used to revise and improve a clinical protocol in the ED context.

Relevance to clinical practice

Newly implemented clinical protocols should incorporate clinician behaviour change assessment, strategy and interventions. Enhancing the self‐efficacy of emergency nurses when performing assessments has the potential to improve patient outcomes and should be included in implementation strategy.

Current practices related to family presence during acute deterioration in adult emergency department patients

AIMS AND OBJECTIVES

To explore the characteristics of and interactions between clinicians, patients and family members during management of the deteriorating adult patient in the emergency department.

BACKGROUND

Previous research into family presence during resuscitation has identified many positive outcomes when families are included. However, over the last three decades the epidemiology of acute clinical deterioration has changed, with a decrease in in-hospital cardiac arrests and an increase in acute clinical deterioration. Despite the decrease in cardiac arrests, research related to family presence continues to focus on care during resuscitation rather than care during acute deterioration.

DESIGN

Descriptive exploratory study using nonparticipatory observation.

METHODS

Five clinical deterioration episodes were observed within a 50-bed, urban, Australian emergency department. Field notes were taken using a semistructured tool to allow for thematic analysis.

RESULTS

Presence, roles and engagement describe the interactions between clinicians, family members and patients while family are present during a patient's episode of deterioration. Presence was classified as no presence, physical presence and therapeutic presence. Clinicians and family members moved through primary, secondary and tertiary roles during patients' deterioration episode. Engagement was observed to be superficial or deep. There was a complex interplay between presence, roles and engagement with each influencing which form the other could take.

CONCLUSIONS

Current practices of managing family during episodes of acute deterioration are complex and multifaceted. There is fluid interplay between presence, roles and engagement during a patient's episode of deterioration.

RELEVANCE TO CLINICAL PRACTICE

This study will contribute to best practice, provide a strong foundation for clinician education and present opportunities for future research.

Emergency department waiting room nurse role: A key informant perspective

BACKGROUND

Emergency departments have become overcrowded with increased waiting times. Strategies to decrease waiting times include time-based key performance indicators and introduction of a waiting room nurse role. The aim of the waiting room nurse role is to expedite care by assessing and managing patients in the waiting room. There is limited literature examining this role.

METHODS

This paper presents results of semi-structured interviews with five key informants to explore why and how the waiting room nurse role was implemented in Australian emergency departments. Data were thematically analysed.

RESULTS

Five key informants from five emergency departments across two Australian jurisdictions (Victoria and New South Wales) reported that the role was introduced to reduce waiting times and improve quality and safety of care in the ED waiting room. Critical to introducing the role was defining and supporting the scope of practice, experience and preparation of the nurses. Role implementation required champions to overcome identified challenges, including funding. There has been limited evaluation of the role.

CONCLUSIONS

The waiting room nurse role was introduced to decrease waiting times and contributed to risk mitigation. Common to all roles was standing orders, while preparation and experience varied. Further research into the role is required.

The effect of a staged, emergency department specific rapid response system on reporting of clinical deterioration

BACKGROUND

Despite emerging evidence regarding clinical deterioration in emergency department (ED) patients, the widespread uptake of rapid response systems (RRS) in EDs has been limited.

AIMS

To evaluate the effect of an ED RRS on reporting of clinical deterioration and determine if there were differences between patients who did, and did not, deteriorate during ED care.

METHODS

A retrospective cross sectional design was used to conduct this single site study in Melbourne, Australia. Stratified random sampling identified 50 patients with shortness of breath, chest pain or abdominal pain per each year studied (2009-2012) giving a total of 600 patients. The intervention was an ED RRS implemented in stages.

RESULTS

The frequency of clinical deterioration was 14.8% (318 episodes/89 patients). Unreported deterioration decreased each year (86.7%; 68.8%; 55.3%; 54.0%, p=0.141). Patients who deteriorated during ED care had a longer median ED length of stay (2.8h; p<0.001), were 31.9% more likely to need hospital admission (p<0.001) and 4.9% more likely to die in hospital (p=0.044).

CONCLUSIONS

A staged ED specific RRS decreased the frequency of unreported clinical deterioration. Controlled multi-site studies of ED specific RRSs are needed to examine the effect of formal ED RRSs on patient outcomes.
