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

Society of Critical Care Medicine Guidelines on Recognizing and Responding to Clinical Deterioration Outside the ICU: 2023

RATIONALE

Clinical deterioration of patients hospitalized outside the ICU is a source of potentially reversible morbidity and mortality. To address this, some acute care hospitals have implemented systems aimed at detecting and responding to such patients.

OBJECTIVES

To provide evidence-based recommendations for hospital clinicians and administrators to optimize recognition and response to clinical deterioration in non-ICU patients.

PANEL DESIGN

The 25-member panel included representatives from medicine, nursing, respiratory therapy, pharmacy, patient/family partners, and clinician-methodologists with expertise in developing evidence-based Clinical Practice Guidelines.

METHODS

We generated actionable questions using the Population, Intervention, Control, and Outcomes (PICO) format and performed a systematic review of the literature to identify and synthesize the best available evidence. We used the Grading of Recommendations Assessment, Development, and Evaluation Approach to determine certainty in the evidence and to formulate recommendations and good practice statements (GPSs).

RESULTS

The panel issued 10 statements on recognizing and responding to non-ICU patients with critical illness. Healthcare personnel and institutions should ensure that all vital sign acquisition is timely and accurate (GPS). We make no recommendation on the use of continuous vital sign monitoring among unselected patients. We suggest focused education for bedside clinicians in signs of clinical deterioration, and we also suggest that patient/family/care partners' concerns be included in decisions to obtain additional opinions and help (both conditional recommendations). We recommend hospital-wide deployment of a rapid response team or medical emergency team (RRT/MET) with explicit activation criteria (strong recommendation). We make no recommendation about RRT/MET professional composition or inclusion of palliative care members on the responding team but suggest that the skill set of responders should include eliciting patients' goals of care (conditional recommendation). Finally, quality improvement processes should be part of a rapid response system.

CONCLUSIONS

The panel provided guidance to inform clinicians and administrators on effective processes to improve the care of patients at-risk for developing critical illness outside the ICU.

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.

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.

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.

What nurses involved in a Medical Emergency Teams consider the most vital areas of knowledge and skill when delivering care to the deteriorating ward patient. A nurse-oriented curriculum development project

INTRODUCTION

Critical care nurses have been involved in Rapid Response Teams since their inception, particularly in medically led RRTs, known as Medical Emergency Teams. It is assumed that critical care skills are required to escalate care for the deteriorating ward patient. However, evidence to support critical care nurses' involvement in METs is anecdotal. Currently, little is known about the educational requirements for nurses involved in RRT or METs.

OBJECTIVES

We aimed to identify and describe what nurses involved in a MET consider the most vital areas of knowledge and skill when delivering care to the deteriorating ward patient.

METHODS

An exploratory descriptive design was used and data was collected at a session of the Australian and New Zealand Intensive Care Society Rapid Response Team (ANZICS-RRT) Conference held at The Gold Coast, Australia in July 2015. All conference delegates were eligible to take part. Conference delegates totalled 293; 194 nurses, 89 doctors and 10 allied health professionals. Data collection took place in three phases, over a 90-minute period. First, demographic data were collected from all participants at the start of data collection. These data were collected using paper-based surveys. Second, extended response surveys; that is, paper-based surveys that asked open-ended questions to elicit free text responses, were used to collect participants' individual responses to the question: "What are the specific theoretical knowledge, skills and behavioural attributes required in a curricula to prepare nurses to be high functioning members of a MET?" Demographic, educational and work characteristics were descriptively analysed using SPSS (version 22). Participants perceptions of what knowledge, skills and attributes are required for nurses to recognise and respond to clinical deterioration were thematically analysed.

RESULTS

Participants were predominantly female (88.3%, n = 91) with 54.4% (n = 56) holding a Bachelor of Nursing. Participants had a median of 20 years (IQR 16) experience as RNs, and a median of 14 years (IQR 13) experience in critical care. Participants formed part of METs frequently, with nearly half the cohort seeing clinically deteriorating patients more than once per day (37.9%, n = 33) or daily (10%, n = 9). Thematic analysis of survey responses revealed four main themes desired in Rapid Response Team Curricula: Clinical Deterioration Theory, Clinical Deterioration Skills, Rapid Response System Governance, and Professionalism and Teamwork.

CONCLUSIONS

We suggest that a curriculum that educates nurses on the specific requirements of assessing, managing and evaluating all aspects of clinical deterioration is now required.

Use of medical emergency call data as a marker of quality of emergency department care in the post-National Emergency Access Target era

Objectives Any new model of care should always be accompanied by rigorous monitoring to ensure that there are no negative consequences, especially any that impact upon patient safety. In 2013, ‘THERMoSTAT’ (Two- Hour Evaluation and Referral Model for Shorter Turnaround Times), an emergency department model of care developed by Royal Brisbane and Women’s Hospital staff was launched to gain efficiencies and improve hospital National Emergency Access Target (NEAT) compliance. The aim of this study was to trial the use of medical emergency call data as a novel marker of the quality of care delivered by our emergency department. Methods Incidence of medical emergency calls for hospital emergency admission patients for the 2 years pre- and 1 year post-THERMoSTAT were compared after standardising for overall hospital activity. Results During the study period, hospital activity increased 10%, and the emergency department experienced a total of 222 645 presentations, 68 000 (30.5%) of which converted into an admission. THERMoSTAT improved NEAT compliance by 17% (from 57.7% to 74.9%) with no change in any patient-safety indicators. A total of 8432 medical emergency calls were made on 5930 patients, 2831 of whom were emergency admissions. After adjusting for hospital activity, there was no change in the average number of patients per week who triggered a medical emergency call after the introduction of THERMoSTAT. These results were reproduced when data was analysed for: total number of inpatients triggering calls; emergency admission patients; and emergency admission patients within the first 24 h or first 4 h of admission. Conclusions This is the first report to investigate the correlation between inpatient medical emergency call incidence and emergency department model of care. Medical emergency call data showed significant promise as a measure of morbidity and as a more direct, objective, simple, quantitative and meaningful measure of patient safety. What is known about the topic? It is well established that extended emergency department lengths of stay are associated with poorer patient outcomes. The corollary of this is not always true however; shorter emergency department length of stay does not automatically translate into better care. Although the underlying philosophy of NEAT is to enhance patient care, there is a risk of negative consequences if NEAT is seen as an end in itself. Many of the commonly used emergency department key performance indicators focus on the timeliness of care and there is a scarcity of easily quantifiable markers that reliably reflect the quality of that care. What does this paper add? This study builds on the concept of medical emergency call incidence as a marker of safety and quality. It explores the utility of using the number of medical emergency calls made in the first few hours of an emergency admission as an indicator of the quality of care delivered by the emergency department. This is significant because it introduces a measure that has a focus that embraces more than the timeliness of care only. What are the implications for practitioners? If medical emergency call incidence in early emergency admissions can be proven to accurately reflect emergency department quality of care then it would provide an easily monitored, objective, quantitative and prompt measure that evaluates dimensions other than timeliness.

The effectiveness of physiologically based early warning or track and trigger systems after triage in adult patients presenting to emergency departments: a systematic review

BACKGROUND

Changes to physiological parameters precede deterioration of ill patients. Early warning and track and trigger systems (TTS) use routine physiological measurements with pre-specified thresholds to identify deteriorating patients and trigger appropriate and timely escalation of care. Patients presenting to the emergency department (ED) are undiagnosed, undifferentiated and of varying acuity, yet the effectiveness and cost-effectiveness of using early warning systems and TTS in this setting is unclear. We aimed to systematically review the evidence on the use, development/validation, clinical effectiveness and cost-effectiveness of physiologically based early warning systems and TTS for the detection of deterioration in adult patients presenting to EDs.

METHODS

We searched for any study design in scientific databases and grey literature resources up to March 2016. Two reviewers independently screened results and conducted quality assessment. One reviewer extracted data with independent verification of 50% by a second reviewer. Only information available in English was included. Due to the heterogeneity of reporting across studies, results were synthesised narratively and in evidence tables.

RESULTS

We identified 6397 citations of which 47 studies and 1 clinical trial registration were included. Although early warning systems are increasingly used in EDs, compliance varies. One non-randomised controlled trial found that using an early warning system in the ED may lead to a change in patient management but may not reduce adverse events; however, this is uncertain, considering the very low quality of evidence. Twenty-eight different early warning systems were developed/validated in 36 studies. There is relatively good evidence on the predictive ability of certain early warning systems on mortality and ICU/hospital admission. No health economic data were identified.

CONCLUSIONS

Early warning systems seem to predict adverse outcomes in adult patients of varying acuity presenting to the ED but there is a lack of high quality comparative studies to examine the effect of using early warning systems on patient outcomes. Such studies should include health economics assessments.

Undertaking an accurate and comprehensive assessment of the acutely ill adult

Accurate assessment of the acutely ill adult who has recently been admitted to hospital, or an inpatient whose condition begins to deteriorate, is becoming a required skill for nurses as people live longer and with a variety of complex conditions, and as nursing skills continue to evolve and develop. This article emphasises the importance of undertaking an accurate and comprehensive patient assessment to ensure that management strategies are implemented in a timely manner. The article also considers the importance of the National Early Warning Score (NEWS), which is a 'track-and-trigger' tool designed to identify patients who are at risk of deterioration. The presentation of shock is considered and how this can be identified using the NEWS. The patient assessment skills required by nurses are discussed and the main signs of patient deterioration, regardless of cause, are outlined. The article also examines the ABCDE (airway, breathing, circulation, disability and exposure) approach to assessment.

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.
