Nurses' experience with patient deterioration and rapid response teams.

BACKGROUND: While timely activation and collaborative teamwork of Rapid Response Teams (RRTs) are crucial to promote a culture of safety and reduce preventable adverse events, these do not always occur. Understanding nurses' perceptions of and experiences with RRTs is important to inform education and policy that improve nurse performance, RRT effectiveness, and patient outcomes. AIM: The aim of this study was to explore nurse perceptions of detecting patient deterioration, deciding to initiate RRTs, and experience during and at conclusion of RRTs. METHODS: A qualitative descriptive study using semi-structured focus group interviews was conducted with 24 nurses in a Chicago area hospital. Interviews were audio-recorded, transcribed verbatim, and coded independently by investigators. Thematic analysis identified and organized patterns of meaning across participants. Several strategies supported trustworthiness. RESULTS: Data revealed five main themes: identification of deterioration, deciding to escalate care, responsiveness of peers/team, communication during rapid responses, and perception of effectiveness. CONCLUSIONS: Findings provide insight into developing a work environment supportive of nurse performance and interprofessional collaboration to improve RRT effectiveness. Nurses described challenges in identification of subtle changes in patient deterioration. Delayed RRT activation was primarily related to negative attitudes of responders and stigma. RRT interventions were often considered a temporary fix leading to subsequent RRTs, especially when patients needing a higher level of care were not transferred. Implications include the need for ongoing RRT monitoring and education on several areas such as patient hand-off, RRT activation, nurse empowerment, interprofessional communication, role delineation, and code status discussions.

Assessment of Hospital Medical Emergency Team Operations in a Tertiary Care Center in Turkey.

BACKGROUND: Rapid Response Teams, strategically devised to mitigate mortality and morbidity stemming from unforeseen deteriorations and cardiac arrests within healthcare facilities, are ubiquitously implemented on a global scale. AIM: The aim of the study is to compare emergency physicians (EPs) and non-EPs on management protocols of Hospital Medical Emergency Teams (HoMET). METHODS: This was a retrospective cross-sectional study. The hospital archive underwent a retrospective scanning process, and patient records were meticulously examined. The assessment encompassed various facets, including demographic characteristics, activation locations, and response and intervention times of HoMET teams, composed of both EPs and other healthcare professionals. Data analysis was conducted using SPSS software version 20.0. RESULTS: A total of 1056 calls were included, with 52% (n = 549) involving male patients. The average age was 67.15 ± 19.45 years. EPs served as the team leader in 53% of the calls. Cardiac arrest was considered in 93.6% of the cases. The EPs group exhibited a higher average patient age, longer intervention times, and shorter arrival times (P < 0.001, P = 0.027, P < 0.001, respectively). A significant difference was observed in the locations of the calls and the groups of calls considering cardiac arrest (P < 0.001, P < 0.001, respectively). CONCLUSION: The optimization of intervention teams is imperative given the persistently high incidence and mortality rates associated with in-hospital cardiac arrests. Leveraging the expertise of EPs in the management of arrests and critical patients can potentially enhance the effectiveness of these teams. Nonetheless, further research is warranted to comprehensively explore and validate this aspect.

Optimizing Pediatric Rapid Response Teams: Stakeholder Focus Groups.

OBJECTIVES: Rapid response teams (RRTs) can improve outcomes in both adult and pediatric hospitals. Most pediatric hospitals have RRT-type systems; however, little is known about stakeholders' perspectives regarding how to optimize RRT quality and efficiency. We aimed to better understand multidisciplinary stakeholder perspectives on how to improve the RRT process. METHODS: We held 4 stakeholder focus groups including floor nurses, pediatric trainees (interns and residents), pediatric hospitalists, and the responding PICU team (PICU fellows and nurses). We used deductive coding to identify potential solutions and subsequent themes. RESULTS: Focus groups identified 10 potential solutions within 3 major themes. Themes included (1) the value of a standardized RRT workflow based on stages, (2) the benefit of promoting a safety culture, and (3) the need to implement ongoing RRT education. Stakeholders described a shared mental model of RRT workflow with important events or tasks occurring within each stage. These stages were coded as 1: trigger, 2: team arrival and information sharing, 3: intervention, and 4: disposition and follow-up. Additional proposed solutions included waiting for the entire team to arrive, a systematic information sharing process, and closed loop communication for follow-up plans for patients remaining on the general care floor. CONCLUSIONS: RRT stakeholder focus groups provide valuable insight into efforts to optimize RRT events. Standardizing RRT workflow into a staged process may facilitate communication and information sharing. Promoting a culture of safety and implementing ongoing education may help reinforce RRT standardization.

Frequency and potential causes of non-beneficial Code Blue activations at a metropolitan teaching hospital.

BACKGROUND: Code Blue activations in patients who are not for resuscitation (NFR) may be regarded as non-beneficial and may cause harm to patients, relatives and hospital staff. AIMS: To estimate the prevalence of non-beneficial Code Blue calls in a metropolitan teaching hospital and identify modifiable factors that could be utilised to reduce these events. METHODS: The study consisted of two parts: (i) a retrospective analysis of all Code Blue activations over a 12-month period using prospectively collected data. Non-beneficial activations were defined as calls made in patients with a NFR order in either the current or any previous hospital admissions and (ii) an anonymous voluntary survey of staff who were present at a Code Blue activation. RESULTS: There were 186 Code Blue activations over the study period, with 48 (25.8%) defined as non-beneficial. Such patients had more comorbidities, previous hospitalisations and greater levels of frailty. Most non-beneficial calls occurred on general wards and more than three-quarters of patients had been reviewed by a consultant prior to the call. The survey determined that despite ward staff having a considerable degree of resuscitation experience, there were deficiencies in understanding of Code Blue criteria, the resuscitation status of patients under their care and the interpretation of goals of care. CONCLUSIONS: Over a quarter of Code Blue calls were deemed non-beneficial. Improving the visibility of NFR status and staff understanding of patient goals of care are needed, along with timely, proactive documentation of NFR status by experienced clinicians.

[Effects of pulmonary embolism response team on the quality of care and clinical outcomes in patients with acute pulmonary embolism].

Objective: To evaluate the effects of pulmonary embolism response team (PERT) on the quality of care and clinical outcomes in patients with acute pulmonary embolism. Methods: This was a single-center retrospective cohort study. Patients with acute pulmonary embolism treated in Beijing Anzhen Hospital Affiliated to Capital Medical University from July 5, 2016 to July 4, 2018 were enrolled. Patients with acute pulmonary embolism who had traditional care from July 5, 2016 to July 4, 2017 (before the implementation of PERT) were classified as PERT pre-intervention group. Patients with acute pulmonary embolism who started PERT care from July 5, 2017 to July 4, 2018 were divided into the PERT intervention group. The diagnosis and treatment information of patients was collected through the electronic medical record system, and the quality of care (time from visit to hospitalization, time from hospitalization to anticoagulation initiation, time from visit to definitive diagnosis, total hospital stay, time in intensive care unit (ICU), hospitalization cost) and clinical outcomes (in-hospital mortality and incidence of bleeding) were compared between the two groups. Results: A total of 210 patients with acute pulmonary embolism, aged (63.3±13.7) years old, with 102 (48.6%) female patients were included. There were 108 cases in PERT pre-intervention group and 102 cases in PERT intervention group. (1) Quality of diagnosis and treatment: there was a statistical significance between the two groups in the distribution of time from diagnosis to definitive diagnosis (P=0.002). Among them, the rate of completion of diagnosis within 24 hours after PERT intervention was higher than that before PERT intervention (80.4% (45/56) vs. 50.0% (34/68), P<0.001). The time from treatment to hospitalization was shorter than that before PERT intervention (180.0 (60.0, 645.0) min vs. 900.0 (298.0, 1 806.5) min, P<0.001). The total length of hospital stay was less than that before PERT intervention (12 (10, 14) d vs. 14 (11, 16) d, P=0.001). There was no statistical significance in the time from hospitalization to anticoagulant therapy, the length of ICU stay and hospitalization cost between the two groups (all P>0.05). (2) Clinical outcomes during hospitalization: There was no statistical significance in the incidence of hemorrhage and mortality between the two groups during hospitalization (both P>0.05). Conclusion: PERT has improved the efficiency of diagnosis and treatment of patients with acute pulmonary embolism and significantly shortened the total hospital stay, but its impact on clinical outcomes still needs further study.

Effectiveness of Rapid Response Team implementation in a tertiary hospital in Egypt: an interventional study.

BACKGROUND: Rapid response teams (RRTs) help in the early recognition of deteriorating patients in hospital wards and provide the needed management at the bedside by a qualified team. RRT implementation is still questionable because there is insufficient evidence regarding its effects. To date, according to our knowledge, no published studies have addressed the effectiveness of RRT implementation on inpatient care outcomes in Egypt. OBJECTIVE: We aimed to assess the impact of an RRT on the rates of inpatient mortality, cardiopulmonary arrest calls and unplanned intensive care unit (ICU) admission in an Egyptian tertiary hospital. METHODS: An interventional study was conducted at a university hospital. Data was evaluated for 24 months before the intervention (January 2018 till December 2019, which included 4242 admissions). The intervention was implemented for 12 months (January 2021 till December 2021), ending with postintervention evaluation of 2338 admissions. RESULTS: RRT implementation was associated with a significant reduction in inpatient mortality rate from 88.93 to 46.44 deaths per 1000 discharges (relative risk reduction (RRR)=0.48; 95% CI, 0.36 to 0.58). Inpatient cardiopulmonary arrest rate decreased from 7.41 to 1.77 calls per 1000 discharges (RRR, 0.76; 95% CI, 0.32 to 0.92), while unplanned ICU admissions decreased from 5.98 to 4.87 per 1000 discharges (RRR, 0.19; 95% CI, -0.65 to 0.60). CONCLUSIONS: RRT implementation was associated with a significantly reduced hospital inpatient mortality rate, cardiopulmonary arrest call rate as well as reduced unplanned ICU admission rate. Our results reveal that RRT can contribute to improving the quality of care in similar settings in developing countries.

Educational Interventions for Rapid Response Team Members: A Narrative Literature Review.

BACKGROUND: Research continues to be conducted on rapid response systems as patient outcomes associated with rapid response team activations are still not consistently showing benefit. One particular area of focus that is a growing area is the literature regarding training and education for individual team members of the rapid response team. OBJECTIVE: The purpose of this narrative review was to describe the current literature regarding educational interventions for rapid response team members. METHODS: This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. To be included in the narrative review, studies needed to be reporting on educational interventional research for rapid response team members of the efferent limb. No studies were excluded based upon study design or publication years. RESULTS: This narrative review included 6 studies. Four studies assessed outcomes associated with rapid response team members, and 2 of the studies assessed patient outcomes associated with implementing education routinely for rapid response teams. All studies found a positive impact of implementing educational interventions. DISCUSSION: Our narrative review found that limited research has been conducted in the area of educational interventions for rapid response team members, and of the articles identified, most did not assess patient-associated outcomes. The findings demonstrate that this area of research is in its early stages, and further work is needed to identify what content should be provided in the education and what educational methodologies should be employed, and to continue to assess patient health outcomes associated with educational interventions for rapid response team members.

Listen to me, I really am sick! Patient and family narratives of clinical deterioration before and during rapid response system intervention.

AIM: To explore patient and family narratives about their recognition and response to clinical deterioration and their interactions with clinicians prior to and during Medical Emergency Team (MET) activations in hospital. BACKGROUND: Research on clinical deterioration has mostly focused on clinicians' roles. Although patients and families can identify subtle cues of early deterioration, little research has focused on their experience of recognising, speaking up and communicating with clinicians during this period of instability. DESIGN: A narrative inquiry. METHODS: Using narrative interviewing techniques, 33 adult patients and 14 family members of patients, who had received a MET call, in one private and one public academic teaching hospital in Melbourne, Australia were interviewed. Narrative analysis was conducted on the data. RESULTS: The core story of help seeking for recognition and response by clinicians to patient deterioration yielded four subplots: (1) identifying deterioration, recognition that something was not right and different from earlier; (2) voicing concerns to their nurse or by family members on their behalf; (3) being heard, desiring a response acknowledging the legitimacy of their concerns; and (4) once concerns were expressed, there was an expectation of and trust in clinicians to act on the concerns and manage the situation. CONCLUSION: Clinical deterioration results in an additional burden for hospitalised patients and families to speak up, seek help and resolve their concerns. Educating patients and families on what to be concerned about and when to notify staff requires a close partnership with clinicians. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Clinicians must create an environment that enables patients and families to speak up. They must be alert to both subjective and objective information, to acknowledge and to act on the information accordingly. REPORTING METHOD: The consolidated criteria for reporting qualitative research (COREQ) guidelines were used for reporting. PATIENT OR PUBLIC CONTRIBUTION: The consumer researcher was involved in design, data analysis and publication preparation.

Development of a novel rapid response event review process for quality improvement.

INTRODUCTION: Rapid response team (RRT) and code activation events occur relatively commonly in inpatient settings. RRT systems have been the subject of a significant amount of analysis, although this has been largely focused on the impact of RRT system implementation and RRT events on patient outcomes. There is reason to believe that the structured assessment of RRT and code events may be an effective way to identify opportunities for system improvement, although no standardised approach to event analysis is widely accepted. We developed and refined a protocolised system of RRT and code event review, focused on sustainable, timely and high value event analysis meant to inform ongoing improvement activities. METHODS: A group of clinicians with expertise in process and quality improvement created a protocolised analytic plan for rapid response event review, piloted and then iteratively optimised a systematic process which was applied to all subsequent cases to be reviewed. RESULTS: Hospitalist reviewers were recruited and trained in a methodical approach. Each reviewer performed a chart review to summarise RRT events, and collect specific variables for each case (coding). Coding was then reviewed for concordance, at monthly interdisciplinary group meetings and 'Action Items' were identified and considered for implementation. In any 12-month period starting in 2021, approximately 12-15 distinct cases per month were reviewed and coded, offering ample opportunities to identify trends and patterns. CONCLUSION: We have developed an innovative process for ongoing review of RRT-Code events. The review process is easy to implement and has allowed for the timely identification of high value improvement opportunities.

Critical care nurses' role in rapid response teams: A qualitative systematic review.

AIM: To analyse the qualitative evidence on the role of critical care nurses in rapid response teams. DESIGN: Qualitative systematic review. METHODS: This qualitative systematic review employed Bettany-Saltikov and McSherry's guidelines and is reported according to the Enhancing Transparency in Reporting the Synthesis of Qualitative Research checklist. Two pairs of blinded researchers screened the articles. The data were synthesised using a thematic analysis approach. DATA SOURCES: A systematic literature search was conducted using the CINAHL, Embase and MEDLINE databases. RESULTS: Seven studies were included, and three main roles were identified: (1) balancing between confidence and fear in clinical encounters, (2) facilitating collaboration and (3) managing challenging power dynamics in decision-making. CONCLUSION: Critical care nurses possess extensive knowledge and skills in providing critical care to patients experiencing deterioration on general wards. They play a vital role in facilitating collaboration between team members and ward staff. Furthermore, within the rapid response team, critical care nurses assume leadership responsibilities by overseeing the comprehensive coordination of patient care and actively engaging in the decision-making process concerning patient care. IMPLICATIONS FOR THE PROFESSION: Highlighting the central role of critical care nurses in rapid response teams as well such a team's benefits in healthcare organisations can promote applications for funding to support further quality assurance of rapid response teams and thus enhance patient safety. IMPACT: Health care organisations can assure the quality of rapid response team by providing economical resources and training. The education providers should facilitate and standardise curriculum for critical care nursing students to achieve necessary knowledge and skills as members in rapid response teams. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Rapid response system for critically ill patients with haematological malignancies: A pre- and post-intervention study.

BACKGROUND: This study aimed to determine whether implementing a rapid response system (RRS) is associated with improved short-term outcomes in critically ill patients with haematological malignancies. METHODS: Our monocentric pre- versus post-intervention study was conducted between January 2012 and April 2020. RRS was activated at early signs of haemodynamic or respiratory failure. The primary outcome was the reduction in Sequential Organ Failure Assessment (SOFA) score on Day 3 after intensive care unit (ICU) admission. Secondary outcomes included time to ICU admission and mortality. RESULTS: A total of 209 patients with a median age of 59 years were enrolled (108 in the pre-intervention period and 101 in the post-intervention period). 22% of them had received an allogeneic transplant. The post-intervention period was associated with a shorter time to ICU admission (195 vs. 390 min, p < .001), a more frequent favourable trend in SOFA score (57% vs. 42%, adjusted odds ratio, 2.02, 95% confidence interval, 1.09 to 3.76), no significant changes in ICU (22% vs. 26%, p = .48) and 1-year (62% vs. 58%, p = .62) mortality rates. CONCLUSION: Detection of early organ failure and activation of an RRS was associated with faster ICU admission and lower SOFA scores on Day 3 of admission in critically ill patients with haematological malignancies.

Rapid Response Systems.

The hospital rapid response system (RRS) is a patient safety and quality intervention that responds quickly to clinical deteriorations on general wards with the goal of preventing cardiopulmonary arrests, reducing hospital mortality, and facilitating triage and level of care escalations. The RRS is one of the first organized, and systematic, elements of the "ICU without walls" model. RRSs have been shown to be effective in preventing deterioration to cardiopulmonary arrest on general hospital wards and reducing total and unexpected hospital mortality. Recent studies have demonstrated that this benefit can be enhanced through targeted improvements and modifications of existing RRSs.

Risk Factors for Deterioration Events in the Pediatric Acute Care Setting.

OBJECTIVES: Rapid response system (RRS) activations resulting in emergency transfers (ETs) and codes outside the ICU are associated with increased mortality and length of stay. We aimed to evaluate the patient and care team characteristics of RRS activations resulting in ETs and codes outside the ICU (together classified as "deterioration events") versus those that did not result in a deterioration event. METHODS: For each RRS activation at our institution from 2019 to 2021, data were gathered on patient demographics and medical diagnoses, care team and treatment factors, and ICU transfer. Descriptive statistics, bivariate analyses, and multivariable logistic regression using a backward elimination model selection method were performed to assess potential risk factors for deterioration events. RESULTS: Over the 3-year period, 1765 RRS activations were identified. Fifty-three (3%) activations were deemed acute care codes, 64 (4%) were noncode ETs, 921 (52%) resulted in nonemergent transfers to an ICU, and 727 (41%) patients remained in an acute care unit. In a multivariable model, any complex chronic condition (adjusted odds ratio, 6.26; 95% confidence interval, 2.83-16.60) and hematology/oncology service (adjusted odds ratio, 2.19; 95% confidence interval, 1.28-3.74) were independent risk factors for a deterioration event. CONCLUSIONS: Patients with medical complexity and patients on the hematology/oncology service had a higher risk of deterioration events than other patients with RRS activations. Further analyzing how our hospital evaluates and treats these specific patient populations is critical as we develop targeted interventions to reduce deterioration events.

Prevalence and characteristics of medical emergency teams in Switzerland: a nationwide survey of intensive care units.

BACKGROUND: Medical Emergency Teams (METs) have been implemented in many hospitals worldwide and are considered an integral part of the hospital patient safety system. However, data on prevalence, staffing and activation criteria of METs are scarce. Such data are important as they may help to identify areas of quality improvement and barriers to implementation of rapid response systems (RRS). This survey aimed to analyze current characteristics, prevalence, and organization of METs in Switzerland. METHODS: We conducted a cross-sectional nationwide online survey, inviting physicians' and nurses' representatives from all registered adult intensive care units (ICU) in Switzerland. RESULTS: Of the 74 hospitals invited to participate in the survey, 57 responded (response rate 77%). We obtained 82 individual responses (from 50 physicians and 32 nurses). Twenty-five hospitals (44%) have a MET in place. In most Swiss hospitals, METs are composed of ICU consultants (64%) and ICU nurses (40%) and are activated by phone, with a usual response time of less than 10 minutes. The most common triggers are single abnormal vital signs (80%), while multiple-parameter warning scores are less commonly used (28%). While more than half of the nurses have regular trainings for their MET members (57%), most MET physicians (63%) do not. Systematic data collection of MET calls occurs in only 43% of institutions. Finally, the most common reasons for not having a MET are staff shortage (44%) and lack of funding (19%). CONCLUSIONS: Less than 50% of Swiss hospitals with an adult ICU have a MET in place. METs in Switzerland typically include an ICU doctor and an ICU nurse and are available 24/7. Major barriers to MET introduction are staff shortage and lack of funding.

The impact of frailty and rapid response team activation on patients admitted to the intensive care unit: A case-control matched, observational, single-centre cohort study.

BACKGROUND: Frailty is a multi-dimensional syndrome associated with mortality and adverse outcomes in patients admitted to the intensive care unit (ICU). Further investigation is warranted to explore the interplay among factors such as frailty, clinical deterioration triggering a medical emergency team (MET) review, and outcomes following admission to the ICU. METHODS: Single-centre, retrospective observational case-control study of adult patients (>18 years) admitted to a medical-surgical ICU with (cases) or without (controls) a preceding MET review between 4 h and 14 days prior. Matching was performed for age, ICU admission diagnosis, Acute Physiology and Chronic Health Evaluation III (APACHE III) score and the 8-point Clinical Frailty Scale (CFS). Cox proportional hazard regression modelling was performed to determine associations with 30-day mortality after admission to ICU. RESULTS: A total of 2314 matched admissions were analysed. Compared to non-frail patients (CFS 1-4), mortality was higher in all frail patients (CFS 5-8), at 31% vs. 13%, and in frail patients admitted after MET review at 33%. After adjusting for age, APACHE, antecedent MET review and CFS in the Cox regression, mortality hazard ratio increased by 26% per CFS point and by 3% per APACHE III point, while a MET review was not an independent predictor. Limitations of medical treatment occurred in 30% of frail patients, either with or without a MET antecedent, and this was five times higher compared to non-frail patients. CONCLUSION: Frail patients admitted to ICU have a high short-term mortality. An antecedent MET event was associated with increased mortality but did not independently predict short-term survival when adjusting for confounding factors. The intrinsic significance of frailty should be primarily considered during MET review of frail patients. This study suggests that routine frailty assessment of hospitalised patients would be helpful to set goals of care when admission to ICU could be considered.

Improving the pre-medical emergency team: the case for a behavioural theoretical lens.

There is mounting evidence that the pre-medical emergency team (pre-MET) of rapid response systems is underutilised in clinical practice due to suboptimal structures and processes and resource constraints. In this perspective article, we argue for examining the pre-MET through a 'Behaviour Change Wheel' lens to improve the pre-MET and maximise the associated patient safety benefits. Using pre-MET communication practices as an example, we illustrate the value of the COM-B model, where clinicians' 'capability', 'opportunity', and 'motivation' drive 'behaviour'. Optimising clinicians' behaviours and establishing failsafe rapid response systems is a complex undertaking; however, examining clinicians' behaviours through the COM-B model enables reframing barriers and facilitators to develop multifaceted and coordinated solutions that are behaviourally and theoretically based. The COM-B model is recommended to clinical governance leaders and health services researchers to explore the underlying causes of behaviour and successfully enact change in the design, implementation, and use of the pre-MET to improve patient safety.

Rapid response teams in the Eastern Mediterranean Region: Results from the baseline survey of country-level capacities, operations and outbreak response capabilities.

The aim of this study is to assess WHO/Eastern Mediterranean region (WHO/EMR) countries capacities, operations and outbreak response capabilities. Cross-sectional study was conducted targeting 22 WHO/EMR countries from May to June 2021. The survey covers 8 domains related to 15 milstones and key performance indicators (KPIs) for RRT. Responses were received from 14 countries. RRTs are adequately organised in 9 countries (64.3%). The mean retention rate of RRT members was 85.5% ± 22.6. Eight countries (57.1%) reported having standard operating procedures, but only three countries (21.4%) reported an established mechanism of operational fund allocation. In the last 6 months, 10,462 (81.9%) alerts were verified during the first 24 h. Outbreak response was completed by the submission of final RRT response reports in 75% of analysed outbreaks. Risk Communication and Community Engagement (RCCE) activities were part of the interventional response in 59.5% of recent outbreaks. Four countries (28.6%) reported an adequate system to assess RRTs operations. The baseline data highlights four areas to focus on: developing and maintaining the multidisciplinary nature of RRTs through training, adequate financing and timely release of funds, capacity and system building for implementing interventions, for instance, RCCE, and establishing national monitoring and evaluation systems for outbreak response.

Qualitative investigation of military surgical resuscitation teams: what are the drivers of success of a rapid response team?

OBJECTIVES: This qualitative study explores the characteristics of a specialised military medical rapid response team (MRRT), the surgical resuscitation team (SRT). Despite mixed evidence of efficacy, civilian MRRTs are widely employed, with significant variation in structure and function. Recent increased use of these teams to mitigate patient risk in challenging healthcare scenarios, such as global pandemics, mass casualty events and resource-constrained health systems, mandates a reconceptualisation of how civilian MRRTs are created, trained and used. Here, we study the core functions and foundational underpinnings of SRTs and discuss how civilian MRRTs might learn from their military counterparts. DESIGN: Semistructured interview-based study using Descriptive Qualitative Research methodology and Thematic Analysis. SETTING: Remote audio interviews conducted via Zoom. PARTICIPANTS: Participants included 15 members of the United States Special Operations Command SRTs, representing all medical specialties of the SRT as well as operational planners. RESULTS: Adaptability was identified as a core function of SRTs and informed by four foundational underpinnings: mission variability, shared values and principles, interpersonal and organisational trust and highly effective teaming. Our findings provide three important insights for civilian MRRTs: (1) team member roles should not be defined by silos of professional specialisation, (2) trust is a key factor in the teaming process and (3) team principles and values result in and are reinforced by organisational trust. CONCLUSION: This study offers the first in-depth investigation of a unique military MRRT. Important insights that may offer benefit to civilian MRRT practices include enabling the breakdown of traditional division of labour, allowing for and promoting deep interpersonal and professional familiarity, and facilitating a cycle of positive reinforcement between teams and organisations. Future investigation of small team limitations, comparability to civilian MRRTs, and the team relationship to the larger organisation are needed to better understand how these teams function in a healthcare system and translate to civilian practice.

Effectiveness of Implementing Modified Early Warning System and Rapid Response Team for General Ward Inpatients.

This retrospective study assessed the effectiveness and impact of implementing a Modified Early Warning System (MEWS) and Rapid Response Team (RRT) for inpatients admitted to the general ward (GW) of a medical center. This study included all inpatients who stayed in GWs from Jan. 2017 to Feb. 2022. We divided inpatients into GWnon-MEWS and GWMEWS groups according to MEWS and RRT implementation in Aug. 2019. The primary outcome, unexpected deterioration, was defined by unplanned admission to intensive care units. We defined the detection performance and effectiveness of MEWS according to if a warning occurred within 24 h before the unplanned ICU admission. There were 129,039 inpatients included in this study, comprising 58,106 GWnon-MEWS and 71,023 GWMEWS. The numbers of inpatients who underwent an unplanned ICU admission in GWnon-MEWS and GWMEWS were 488 (.84%) and 468 (.66%), respectively, indicating that the implementation significantly reduced unexpected deterioration (p < .0001). Besides, 1,551,525 times MEWS assessments were executed for the GWMEWS. The sensitivity, specificity, positive predicted value, and negative predicted value of the MEWS were 29.9%, 98.7%, 7.09%, and 99.76%, respectively. A total of 1,568 warning signs accurately occurred within the 24 h before an unplanned ICU admission. Among them, 428 (27.3%) met the criteria for automatically calling RRT, and 1,140 signs necessitated the nursing staff to decide if they needed to call RRT. Implementing MEWS and RRT increases nursing staff's monitoring and interventions and reduces unplanned ICU admissions.

Effectiveness of an Artificial Intelligence-Enabled Intervention for Detecting Clinical Deterioration.

Importance: Inpatient clinical deterioration is associated with substantial morbidity and mortality but may be easily missed by clinicians. Early warning scores have been developed to alert clinicians to patients at high risk of clinical deterioration, but there is limited evidence for their effectiveness. Objective: To evaluate the effectiveness of an artificial intelligence deterioration model-enabled intervention to reduce the risk of escalations in care among hospitalized patients using a study design that facilitates stronger causal inference. Design, Setting, and Participants: This cohort study used a regression discontinuity design that controlled for confounding and was based on Epic Deterioration Index (EDI; Epic Systems Corporation) prediction model scores. Compared with other observational research, the regression discontinuity design facilitates causal analysis. Hospitalized adults were included from 4 general internal medicine units in 1 academic hospital from January 17, 2021, through November 16, 2022. Exposure: An artificial intelligence deterioration model-enabled intervention, consisting of alerts based on an EDI score threshold with an associated collaborative workflow among nurses and physicians. Main Outcomes and Measures: The primary outcome was escalations in care, including rapid response team activation, transfer to the intensive care unit, or cardiopulmonary arrest during hospitalization. Results: During the study, 9938 patients were admitted to 1 of the 4 units, with 963 patients (median [IQR] age, 76.1 [64.2-86.2] years; 498 males [52.3%]) included within the primary regression discontinuity analysis. The median (IQR) Elixhauser Comorbidity Index score in the primary analysis cohort was 10 (0-24). The intervention was associated with a -10.4-percentage point (95% CI, -20.1 to -0.8 percentage points; P = .03) absolute risk reduction in the primary outcome for patients at the EDI score threshold. There was no evidence of a discontinuity in measured confounders at the EDI score threshold. Conclusions and Relevance: Using a regression discontinuity design, this cohort study found that the implementation of an artificial intelligence deterioration model-enabled intervention was associated with a significantly decreased risk of escalations in care among inpatients. These results provide evidence for the effectiveness of this intervention and support its further expansion and testing in other care settings.
