Nursing Training for Early Clinical Deterioration Risk Assessment: Protocol for an Implementation Study.

During the hospitalization period, it is possible to observe considerable changes in the vital parameters of patients, which may require emergency interventions or intensive treatment. The alteration of signs and symptoms that lead to physiological instability that can worsen the clinical picture with progression to shock, respiratory failure, or cardiorespiratory arrest is currently defined as clinical deterioration. Identifying signs of clinical deterioration at an early stage can lead to substantial decreases in mortality rates, the need for emergency interventions, and unscheduled treatments in intensive care units. Identifying and appropriately referring patients who show signs of clinical deterioration can be facilitated by applying early warning systems that provide rapid responses. The nursing team is usually the first to identify clinical changes in patients. Although the literature demonstrates that early recognition of clinical deterioration is the key to early intervention and leads to better outcomes, we only sometimes pursue the most appropriate intervention. This study aims to implement and evaluate an evidence-based professional training program designed for nurses and coordinated by a nurse using the "just-in-time" methodology and the National Early Warning Score 2 (NEWS2) to assess the risk of early clinical deterioration and appropriate referral in inpatient units of a public university hospital in southeastern Brazil. This intervention protocol is structured according to the recommendations of the SPIRIT (Standard Protocol Items: Recommendations for Interventional Trials) Declaration 2013. The type of training to be offered, "Just-in-Time Training," consists of a teaching modality that facilitates the delivery of a time-based and work-based education, with greater emphasis on providing on-the-job learning as needed. A qualitative stage will also be conducted through focus groups and interviews with nurses to verify the factors that influence the professional practice related to the early evaluation of the clinic. A script of previously tested questions will guide and standardize the different groups. The data will define the intervention's elements: the strategy, the type of training, the location, the teaching methodology, and the teaching material. The study has received authorization from the ethics committee, and participants will be recruited in July 2023. Data collection should be completed in October of the same year. The results obtained at the end of this research will be shared with the participating nursing team through the presentation of reports. In addition, the research results will be submitted to scientific journals and presented at international scientific conferences. This study will support nurses and possibly other clinicians to improve their approach to early recognition of clinical deterioration in patients.

Pediatric Early Warning System in the Short Stay Unit

INTRODUCTION: Pediatric Early Warning Scores were developed as standardized clinical aides for early recognition of clinical deterioration in children. These systems improve situational awareness among professionals. A major concern is the workload increase. After implementation in the Short Stay Unit, we intended to evaluate its effectiveness in our population.METHODS: We reviewed medical records of children admitted to the Short Stay Unit between July 2017 and February 2020. We developed a statistical analysis to evaluate the test performance.RESULTS: One thousand three hundred twenty-three patients were included (median age 3.07 years-old); 5.7% were considered to have clinical deterioration (maximum score median 7.00 vs 2.00) (p<0.001). The area under the ROC curve was 0.947. Defining 4 as cut-off value, the sensitivity is 97.1% (specificity 82.7%).CONCLUSION: This score proved to be a good test for early identification of clinical deterioration in our population.

Using a Clinical Triggers System to Improve Early Recognition of Clinical Changes.

A medical-surgical telemetry unit implemented a clinical triggers system for early recognition of clinical deterioration and bedside management between nurses and providers. The goal was to decrease cardiopulmonary arrest events. A clinical triggers system was developed to help nurses to identify clinical markers early and advocate for prompt bedside assessment and interventions. When clinical triggers were identified, the nurse notified the provider, who performed a bedside assessment within 15 minutes. If the provider did not respond promptly, the rapid response team was activated. Before intervention, the unit experienced 14 cardiopulmonary arrest events (rate of 1.37 per 1000 patient days). Incidences decreased annually to 5, 4, and 3 events (rates of 0.49, 0.39, and 0.3 per 1000 patient days) during the 3-year implementation period. The clinical triggers system was successful in achieving the project objective of decreasing unit cardiopulmonary arrest events through early recognition and response to patient deterioration during the implementation period. The clinical nurse specialist helped nurses to use the clinical triggers system to detect and respond to clinical changes. Nurses were empowered to address concerns and promote patient safety.

Developing a real-time detection tool and an early warning score using a continuous wearable multi-parameter monitor.

Background: Currently-used tools for early recognition of clinical deterioration have high sensitivity, but with low specificity and are based on infrequent measurements. We aimed to develop a pre-symptomatic and real-time detection and warning tool for potential patients' deterioration based on multi-parameter real-time warning score (MPRT-WS). Methods: A total of more than 2 million measurements were collected, pooled, and analyzed from 521 participants, of which 361 were patients in general wards defined at high-risk for deterioration and 160 were healthy participants allocation as controls. The risk score stratification was based on cutoffs of multiple physiological parameters predefined by a panel of specialists, and included heart rate, blood oxygen saturation (SpO2), respiratory rate, cuffless systolic and diastolic blood pressure (SBP and DBP), body temperature, stroke volume (SV), cardiac output, and systemic vascular resistance (SVR), recorded every 5min for a period of up to 72h. The data was used to define the various risk levels of a real-time detection and warning tool, comparing it with the clinically-used National Early Warning Score (NEWS). Results: When comparing risk levels among patients using both tools, 92.6%, 6.1%, and 1.3% of the readings were defined as "Low", "Medium", and "High" risk with NEWS, and 92.9%, 6.4%, and 0.7%, respectively, with MPRT-WS (p = 0.863 between tools). Among the 39 patients that deteriorated, 30 patients received 'High' or 'Urgent' using the MPRT-WS (42.7 ± 49.1h before they deteriorated), and only 6 received 'High' score using the NEWS. The main abnormal vitals for the MPRT-WS were SpO2, SBP, and SV for the "Urgent" risk level, DBP, SVR, and SBP for the "High" risk level, and DBP, SpO2, and SVR for the "Medium" risk level. Conclusion: As the new detection and warning tool is based on highly-frequent monitoring capabilities, it provides medical teams with timely alerts of pre-symptomatic and real-time deterioration.

Arriving Safely: Decreasing Rapid Escalations in Care for Incoming Transported Pediatric Patients.

We created an escalation algorithm utilizing PEWS scores and direct lines of communication between emergency medical technicians and receiving physicians. Audit and feedback increased the adoption of the process. We defined rapid escalations as transfer to a higher level of care within 6 hours of admission. PEWS score completion increased from a mean of 48% to 70%. This result varied by emergency medical technician crew level of care. Eleven percent (n = 114) of PEWS scores required physician notification, 20% (n = 23) of which resulted in interventions en route. There were no differences in rapid escalation rates over time, but it remained low at <2% of all incoming transported patients. Some crew members report improved communication with hospital providers and feel more empowered to speak up when a patient's assessment is not as expected following algorithm implementation. This project improved PEWS score completion and maintained a low rate of rapid escalations of care among incoming transfers.

Exploration of Ward-Based Nurses' Perspectives on Their Preparedness to Recognize Clinical Deterioration: A Scoping Review.

Despite initiatives in the early recognition of clinical deterioration, the incidence of failure to recognize clinical deterioration in patients continues to occur contributing to the ongoing rise of in-hospital mortality and morbidity. The aim of the study was to explore and appraise the research evidence that related to ward-based nurses' preparedness to recognize the clinically deteriorating patient. A scoping review was undertaken as this approach enabled the researchers to investigate the breadth of the available evidence through broad inclusion criteria. A comprehensive database search was conducted through the Cochrane Library; Cumulative Index to Nursing and Allied Health Literature; MEDLINE; ProQuest; PubMed; and Wiley Online Library. Each article was critically appraised and analyzed using a critical appraisal tool and thematic analysis, respectively. The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews checklist. Twelve primary sources of literature met the eligibility criteria. Through thematic analyses 6 primary themes were identified: implication of experience on preparedness; interprofessional and intraprofessional relationships; knowledge of calling criteria, process and procedures; requirement for a supportive system and culture; existence of hierarchy within healthcare impacting care; and clinical deterioration as an education opportunity. This review identified central issues that impacted on ward-based nurses' preparedness. Further development of collaborative, supportive professional relationships across-and-within disciplines is needed. Effective use of clinical deterioration situations as educational opportunities would also assist nurses' preparedness through skill and knowledge development. However, more research evidence will be needed because of the limited data available on the topic.

The transcultural adaptation and validation of the Chinese version of the Attitudes Toward Recognizing Early and Noticeable Deterioration scale.

In China, clinical deterioration events present a real problem for every clinical nurse. Patient deterioration is determined in part by nurses' attitudes toward early recognition of clinical deterioration. However, research on attitudes toward the early identification of clinical deterioration is still in its infancy, and even less research has been done on ward nurses' attitudes toward the early identification of clinical deterioration. To drive behavioral change and improve the care of deteriorating patients, nurses need comprehensive, valid, and reliable tools to assess their attitudes toward early identification of deterioration. In this study, we aimed to translate the Attitudes Toward Recognizing Early and Noticeable Deterioration (ATREND) scale into Chinese and to assess its validity and reliability tests. From March 2022 to July 2022, the ATREND scale was translated, back-translated, and cross-culturally adapted into the Chinese version using a modified Brislin translation model. Then, 460 ward nurses were recruited from tertiary Grade A general hospitals in two cities: Shenyang and Jinzhou in Liaoning Province, China. Reliability analyses were conducted using internal consistency, split-half, and test-retest reliability. We convened a committee of experts to determine the validity of the content. Tests of the structural validity of the scale were conducted using exploratory and validation factor analyses. The Cronbach's α value of the Chinese version of the ATREND scale was 0.804, and the Cronbach's α value of the dimensions ranged from 0.782 to 0.863. The split-half reliability and test-retest reliability were 0.846 and 0.711, respectively. Furthermore, the scale has an index of content validity of 0.922, indicating a high level of content validity. In exploratory factor analysis, eigenvalues, total variance explained, and scree plot supported a three-factor structure. The three-factor model supported by this study was confirmed by confirmatory factor analysis (CFA). Moreover, the model fitting indexes (e.g., χ 2/DF = 1.498, GFI = 0.954, RMSEA = 0.047) were all within acceptable limits based on the CFA. The Chinese version of the scale is reliable and valid among ward nurses. Nursing educators and clinicians will be able to develop targeted educational programs to enhance the competence and behaviors of Chinese ward nurses in recognizing clinical deterioration. It will be based on the developed scale to assess Chinese nurses' attitudes and practices regarding early recognition of clinical deterioration. As a result, it is necessary to consider the Chinese scale's three-factor structure. The developed three-factor structured scale will assess Chinese ward nurses' attitudes and practices toward patient observation and vital sign-monitoring empowerment, enlightening them on the importance of patient observation, encouraging ward nurses to use a wider range of patient assessment techniques to capture early signs of clinical deterioration, and helping ward nurses to develop clinical confidence to monitor clinical deterioration.

Nurses\u2019 experiences with continuous vital sign monitoring on the general surgical ward: a qualitative study based on the Behaviour Change Wheel

BackgroundTo support early recognition of clinical deterioration on a general ward continuous vital signs monitoring (CMVS) systems using wearable devices are increasingly being investigated. Although nurses play a crucial role in successful implementation, reported nurse adoption and acceptance scores vary significantly. In-depth insight into the perspectives of nurses regarding CMVS is lacking. To this end, we applied a theoretical approach for behaviour change derived from the Behaviour Change Wheel (BCW).AimTo provide insight in the capability, opportunity and motivation of nurses working with CMVS, in order to inform future implementation efforts.MethodsA qualitative study was conducted, including twelve nurses of a surgical ward in a tertiary teaching hospital with previous experience of working with CMVS. Semi-structured interviews were audiotaped, transcribed verbatim, and analysed using thematic analysis. The results were mapped onto the Capability, Opportunity, Motivation – Behaviour (COM-B) model of the BCW.ResultsFive key themes emerged. The theme ‘Learning and coaching on the job’ linked to Capability. Nurses favoured learning about CVSM by dealing with it in daily practice. Receiving bedside guidance and coaching was perceived as important. The theme ‘interpretation of vital sign trends’ also linked to Capability. Nurses mentioned the novelty of monitoring vital sign trends of patients on wards. The theme ‘Management of alarms’ linked to Opportunity. Nurses perceived the (false) alarms generated by the system as excessive resulting in feelings of irritation and uncertainty. The theme ‘Integration and compatibility with clinical workflow’ linked to Opportunity. CVSM was experienced as helpful and easy to use, although integration in mobile devices and the EMR was highly favoured and the management of clinical workflows would need improvement. The theme ‘Added value for nursing care’ linked to Motivation. All nurses recognized the potential added value of CVSM for postoperative care.ConclusionOur findings suggest all parts of the COM-B model should be considered when implementing CVSM on general wards. When the themes in Capability and Opportunity are not properly addressed by selecting interventions and policy categories, this may negatively influence the Motivation and may compromise successful implementation.

Aplicação de um sistema de pontuação de alerta precoce em uma enfermaria pediátrica de um hospital terciário

OBJECTIVE: To evaluate the performance the Brighton Pediatric Early Warning Score for an early identification of clinical deterioration in children admitted to the pediatric ward of a tertiary hospital. METHODS: A prospective cohort observational study, involving 325 children with acute illnesses admitted to a pediatric ward, aged 29 days to 13 years, between August 2018 and March 2020. To assess the Brighton Pediatric Early Warning Score diagnostic accuracy, it was used the Cardiff and Vale Pediatric Early Warning System as reference, and the software used was the R Core Team 2020. The effectiveness of the Brighton Pediatric Early Warning Score was assessed using the indicators of sensitivity, specificity, positive predictive value, negative predictive value, area under the ROC curve, number of true positives and negatives and false positives and negatives. RESULTS: The Brighton Pediatric Early Warning Score showed a sensitivity of 19.2%, a specificity of 99.1%, a positive predictive value of 90.5%, a negative predictive value of 73.7%, and an area under the ROC curve of 0.839. In addition to that, for scores larger than 3, there were 19 true positives, 224 true negatives, 2 false positives and 80 false negatives. CONCLUSION: The Brighton Pediatric Early Warning Score performed well in the scenario analysis chosen by this research, showing how easy it is to use it for an early recognition of clinical deterioration in children admitted to pediatric wards.

In-hospital Mortality and the Predictive Ability of the Modified Early Warning Score in Ghana: Single-Center, Retrospective Study.

The modified early warning score (MEWS) is an objective measure of illness severity that promotes early recognition of clinical deterioration in critically ill patients. Its primary use is to facilitate faster intervention or increase the level of care. Despite its adoption in some African countries, MEWS is not standard of care in Ghana. In order to facilitate the use of such a tool, we assessed whether MEWS, or a combination of the more limited data that are routinely collected in current clinical practice, can be used predict to mortality among critically ill inpatients at the Korle-Bu Teaching Hospital in Accra, Ghana. The aim of this study was to identify the predictive ability of MEWS for medical inpatients at risk of mortality and its comparability to a measure combining routinely measured physiologic parameters (limited MEWS [LMEWS]). We conducted a retrospective study of medical inpatients, aged ≥13 years and admitted to the Korle-Bu Teaching Hospital from January 2017 to March 2019. Routine vital signs at 48 hours post admission were coded to obtain LMEWS values. The level of consciousness was imputed from medical records and combined with LMEWS to obtain the full MEWS value. A predictive model comparing mortality among patients with a significant MEWS value or LMEWS ≥4 versus a nonsignificant MEWS value or LMEWS <4 was designed using multiple logistic regression and internally validated for predictive accuracy, using the receiver operating characteristic (ROC) curve. A total of 112 patients were included in the study. The adjusted odds of death comparing patients with a significant MEWS to patients with a nonsignificant MEWS was 6.33 (95% CI 1.96-20.48). Similarly, the adjusted odds of death comparing patients with a significant versus nonsignificant LMEWS value was 8.22 (95% CI 2.45-27.56). The ROC curve for each analysis had a C-statistic of 0.83 and 0.84, respectively. LMEWS is a good predictor of mortality and comparable to MEWS. Adoption of LMEWS can be implemented now using currently available data to identify medical inpatients at risk of death in order to improve care.

Implementation of Wearable Sensors and Digital Alerting Systems in Secondary Care: Protocol for a Real-World Prospective Study Evaluating Clinical Outcomes.

BackgroundAdvancements in wearable sensors have caused a resurgence in their use, particularly because their miniaturization offers ambulatory advantages while performing continuous vital sign monitoring. Digital alerts can be generated following early recognition of clinical deterioration through breaches of set parameter thresholds, permitting earlier intervention. However, a systematic real-world evaluation of these alerting systems has yet to be conducted, and their efficacy remains unknown.ObjectiveThe aim of this study is to implement wearable sensors and digital alerting systems in acute general wards to evaluate the resultant clinical outcomes.MethodsParticipants on acute general wards will be screened and recruited into a trial with a pre-post implementation design. In the preimplementation phase, the SensiumVitals monitoring system, which continuously measures temperature, heart, and respiratory rates, will be used for monitoring alongside usual care. In the postimplementation phase, alerts will be generated from the SensiumVitals system when pre-established thresholds for vital parameters have been crossed, requiring acknowledgement from health care staff; subsequent clinical outcomes will be analyzed.ResultsEnrolment is currently underway, having started in September 2017, and is anticipated to end shortly. Data analysis is expected to be completed in 2021.ConclusionsThis study will offer insight into the implementation of digital health technologies within a health care trust and aims to describe the effectiveness of wearable sensors for ambulatory continuous monitoring and digital alerts on clinical outcomes in acute general ward settings.Trial RegistrationClinicalTrials.gov NCT04638738; https://clinicaltrials.gov/ct2/show/NCT04638738.International Registered Report Identifier (IRRID)DERR1-10.2196/26240

Expectations of Continuous Vital Signs Monitoring for Recognizing Complications After Esophagectomy: Interview Study Among Nurses and Surgeons.

BackgroundPatients undergoing esophagectomy are at serious risk of developing postoperative complications. To support early recognition of clinical deterioration, wireless sensor technologies that enable continuous vital signs monitoring in a ward setting are emerging.ObjectiveThis study explored nurses’ and surgeons’ expectations of the potential effectiveness and impact of continuous wireless vital signs monitoring in patients admitted to the ward after esophagectomy.MethodsSemistructured interviews were conducted at 3 esophageal cancer centers in the Netherlands. In each center, 2 nurses and 2 surgeons were interviewed regarding their expectations of continuous vital signs monitoring for early recognition of complications after esophagectomy. Historical data of patient characteristics and clinical outcomes were collected in each center and presented to the local participants to support estimations on clinical outcome.ResultsThe majority of nurses and surgeons expected that continuous vital signs monitoring could contribute to the earlier recognition of deterioration and result in earlier treatment for postoperative complications, although the effective time gain would depend on patient and situational factors. Their expectations regarding the impact of potential earlier diagnosis on clinical outcomes varied. Nevertheless, most caregivers would consider implementing continuous monitoring in the surgical ward to support patient monitoring after esophagectomy.ConclusionsCaregivers expected that wireless vital signs monitoring would provide opportunities for early detection of postoperative complications in patients undergoing esophagectomy admitted to the ward and prevent sequelae under certain circumstances. As the technology matures, clinical outcome studies will be necessary to objectify these expectations and further investigate overall effects on patient outcome.

Abstract 288: Rapid Response Team Implementation Associated with Reductions in In-hospital Mortality Rate and Hospitalization Costs: A Retrospective Analysis

Introduction: Early recognition of clinical deterioration in inpatient subjects seems to be one of the main factors associated with prevention of in-hospital severe adverse events occurrence. Previous studies failed to demonstrate that the implementation of a rapid response team (RRT) could reduce in-hospital mortality rate. Hypothesis: Could a RRT implementation reduces in-hospital mortality and/or hospitalizations costs in a private general hospital in Brazil? Methods: This is a retrospective cohort built from data of electronic medical database of consecutive adult inpatients admitted to general wards who had to be transferred to an ICU after an acute clinical deterioration between May 1st, 2012 and June 30th, 2016. Subjects were divided into two groups as follows: group 1 (G1) with those admitted to ICU before RRT implementation on June 1st, 2014 and group 2 (G2) with the ones admitted to ICU after the implementation. All patients in G2 received care by the RRT before ICU admittance. In cases in which a patient had more than one hospital admission, only the first admittance was used for analyses. Results: Patients data are shown in table 1.Outcome data are shown in table 2. Conclusions: From these data, it is possible to infer that this RRT implementation at this hospital was associated with improvement in clinical outcomes of inpatients who needed an ICU admittance after an acute clinical deterioration, as well as a significant reduction of their hospitalization costs. These data reinforce the hypotheses that MERIT study was underpowered. Further multicenter randomized trials, with appropriate statistical power, shall be proposed to address these questions.

Can Routinely Collected, Patient-Reported Wellness Predict National Early Warning Scores? A Multilevel Modeling Approach.

ObjectiveMeasures exist to improve early recognition of and response to deteriorating patients in hospital. However, management of critical illness remains a problem globally; in the United Kingdom, 7% of the deaths reported to National Reporting and Learning System from acute hospitals in 2015 related to failure to recognize or respond to deterioration. The current study explored whether routinely recording patient-reported wellness is associated with objective measures of physiology to support early recognition of hospitalized deteriorating patients.MethodsA prospective observation study design was used. Nurses on four inpatient wards were invited to participate and record patient-reported wellness during every routine observation (where possible) using an electronic observation system. Linear multilevel modeling was used to examine the relationship between patient-reported wellness, and national early warning scores (NEWS), and whether patient-reported wellness predicted subsequent NEWS.ResultsA significant positive relationship was found between patient-reported wellness and NEWS recorded at the next observation while controlling for baseline NEWS (β = 0.180, P = 0.033). A significant positive relationship between patient-reported wellness and NEWS (β = 0.229, P = 0.005) recorded during an observation 24 hours later while controlling for baseline NEWS was also found. Patient-reported wellness added to the predictive model for subsequent NEWS.ConclusionsThe preliminary findings suggest that patient-reported wellness may predict subsequent improvement or decline in their condition as indicated by objective measurements of physiology (NEWS). Routinely recording patient-reported wellness during observation shows promise for supporting the early recognition of clinical deterioration in practice, although confirmation in larger-scale studies is required.

528 Patient Outcomes Post Medical Emergency Team Calls and User Compliance of Track and Trigger Based Observation and Response Chart in Cardiology Patients

Early recognition of clinical deterioration has been associated with a lower level of intervention and reduced adverse events. A widely used approach in Australia is the Medical Emergency Team (MET) system. We conducted a prospective observational study of all inpatients under the general cardiology and heart failure(HF) teams for 30 days. Information was collected from the observation chart and the hospital database. There were 23 MET calls for total of 443 patient episodes. The indication for MET call are listed in the table. There were 20 episodes with appropriate modifications in place hence MET was not called. There was only 1 episode where MET call and 4 episodes where preMET call was inappropriately not called. Of the patients (n=27) who met the MET call criteria during their stay, 63% were admitted under HF team. 22% of the patients who met the MET call criteria required a procedure/ device insertion, 15% required ICU admission and 15% died. The average length of stay was 6.41 days. The higher MET call rate in heart failure vs general cardiology patients is expected and reflects the difference in patient population and co-morbidities. Most patients requiring activation of MET system were critically ill, requiring emergency treatment or procedure highlighting importance of this system. Continued exploration of workplace issues influencing the recognition and responses to unmet needs of a deteriorating patient in cardiology ward is recommended.Tabled 1MET criteriaTotal number of callsPulse<40bpm4Pulse>140bpm11SBP<90mmHg4Resp Rate >302RN worried2Total23 Open table in a new tab

Implementation study of a 5-component pediatric early warning system (PEWS) in an emergency department in British Columbia, Canada, to inform provincial scale up

BackgroundThe rapid identification of deterioration in the pediatric population is complex, particularly in the emergency department (ED). A comprehensive multi-faceted Pediatric Early Warning System (PEWS) might maximize early recognition of clinical deterioration and provide a structured process for the reassessment and escalation of care. The objective of the study was to evaluate the implementation fidelity, effectiveness, and utility of a 5-component PEWS implemented in the ED of an urban public general hospital in British Columbia, Canada, and to guide provincial scale up.MethodsWe used a before-and-after design to evaluate the implementation fidelity, effectiveness, and utility of a 5-component PEWS (pediatric assessment flowsheet, PEWS score, situational awareness, escalation aid, and communication framework). Sources of data included patient medical records, surveys of direct care staff, and key-informant interviews. Data were analyzed using mixed-methods approaches.ResultsThe majority of medical records had documented PEWS scores at triage (80%) and first bedside assessment (81%), indicating that the intervention was implemented with high fidelity. The intervention was effective in increasing vital signs documentation, both at first beside assessment (84% increase) and throughout the ED stay (> 100% increase), in improving staff’s self-perceived knowledge and confidence in providing pediatric care, and self-reported communication between staff. Satisfaction levels were high with the PEWS scoring system, flowsheet, escalation aid, and to a lesser extent with the situational awareness tool and communication framework. Reasons for dissatisfaction included increased paperwork and incidence of false-positives. Overall, the majority of providers indicated that implementation of PEWS and completing a PEWS score at triage alongside the Canadian Triage and Acuity Scale (CTAS) added value to pediatric care in the ED. Results also suggest that the intervention is aligned with current practice in the ED.ConclusionOur study shows that high-fidelity implementation of PEWS in the ED is feasible. We also show that a multi-component PEWS can be effective in improving pediatric care and be well-accepted by staff. Results and lessons learned from this pilot study are being used to scale up implementation of PEWS in ED settings across the province of British Columbia.

Seeing the whole picture in enrolled and registered nurses’ experiences in recognizing clinical deterioration in general ward patients: A qualitative study

BackgroundThe implementation of early warning scoring systems and medical emergency teams that aim to reduce failure to rescue in general wards is only effective if frontline nurses can recognize and act on clinical deterioration in a timely manner. While much of the research to date has primarily focused on registered nurses as recognizers of clinical deterioration, little research has sought to explore the role of enrolled nurses in recognizing clinical deterioration and to provide a big picture of how enrolled and registered nurses recognize clinical deterioration in general ward patients. ObjectivesTo conduct an exploration of the experiences of enrolled and registered nurses in recognizing clinically deteriorating patients in general wards. DesignA qualitative, descriptive design. SettingGeneral wards at a 1,000-bed acute general hospital in Singapore. ParticipantsA purposive sample of 22 enrolled and registered nurses who had at least 6 months of nursing experience and who were working in the general wards. MethodsIndividual semi-structured interviews were conducted between October 2016 and February 2017. Interviews were transcribed verbatim and analyzed using thematic analysis. ResultsFour salient themes emerged from the data analysis. The first, ‘Having a sense of knowing’, illustrates how knowing a patient and past experiences facilitated the early recognition of clinical deterioration before the patient turned haemodynamically unstable. The second, ‘Patient assessment practices’, depicts the physical assessment skills that nurses used to detect clinical deterioration. The third, ‘Delegation of routine patient care and assessment to enrolled nurses’, demonstrates that nursing activities were delegated to enrolled nurses with lesser directional and supervisory aspects that “delegation” implies, which can potentially compromise patient safety. The fourth, ‘Missing the big picture’, identifies overwhelming workload and fixation on specific parameters of a patient as reasons for both enrolled and registered nurses missing the big picture of the patient’s deterioration. ConclusionsThis study provides a snapshot of the recognition of clinical deterioration among enrolled and registered nurses in general wards. Our findings illuminate the need to support the roles of enrolled and registered nurses, with an emphasis on patient assessment and strengthening collaborative practices among nurses, to improve early recognition and timely treatment of clinically deteriorating ward patients.

Utility of photoplethysmography for heart rate estimation among inpatients.

The accuracy of photoplethysmography (PPG) for heart rate (HR) estimation in cardiac arrhythmia is unknown. PPG-HR was evaluated in 112 hospitalised inpatients (cardiac arrhythmias (n = 60), sinus rhythm (n = 52)) using a continuous electrocardiogram monitoring as a reference standard. Strong agreement was observed in sinus rhythm HR < 100 and atrial flutter (bias 1 beat), modest agreement in sinus tachycardia (bias 24 beats) and complete heart block (bias -6 beats) and weak agreement with significant HR underestimation was seen in atrial fibrillation (bias 23 beats). Routine utilisation of PPG for HR estimation may delay early recognition of clinical deterioration in certain arrhythmias and sinus tachycardia.

Clinician Perceptions of an Early Warning System on Patient Safety

The Pediatric Early Warning Score (PEWS) aims to improve early recognition of clinical deterioration and is widely used despite lacking evidence of effects on outcome measures such as hospital mortality. In this qualitative study, we aimed to study effects of both PEWS and the locally designed risk stratification system by focusing on professionals' perception of their performance. We also sought to gain insight into the perceived effects of PEWS and the risk stratification system on patient safety and to unravel the underlying mechanisms. A single-center cross-sectional observational study whereby 16 semistructured interviews were held with selected health care professionals focusing on perceived effects and underlying mechanisms. Interviews were transcribed verbatim and coded without using a predetermined set of themes. Coding from semistructured interviews demonstrated that perceived value was related to effects on different levels of Endsley and co-workers' situational awareness (SA) model. PEWS mainly improved level 1 SA, whereas the risk stratification system also seemed to improve levels 2 and 3 SA. This study shows clear effects of PEWS on SA among professionals. It also points to the additional value of other risk factor stratification systems to help further improve PEWS functioning.

Effectiveness of provider strategies for the early recognition of clinical deterioration due to sepsis in pediatric patients: a systematic review protocol.

The objective of this review is to determine the effectiveness of provider strategies for the early recognition of clinical deterioration due to sepsis in pediatric patients. Specifically, the review question is: among pediatric, hospitalized patients, up to 18 years of age, what is the effectiveness of clinical assessment compared with use of early recognition screening tools for the recognition of clinical deterioration due to sepsis?
