Pediatric intraoperative cardiopulmonary arrests: A survey to evaluate if Medical Emergency Teams are utilized in pediatric operating rooms.

BACKGROUND: Studies have shown that standardized code teams may improve outcomes following cardiac arrests. Pediatric intra-operative cardiac arrests are rare events and are associated with a mortality rate of 18%. There is limited data available regarding use Medical Emergency Team (MET) response to pediatric intra-operative cardiac arrest. The purpose of this study was to identify the use of MET in response to pediatric intraoperative cardiac arrest as an exploratory step in establishing evidence-based standardized practice across the hospital for training and management of this rare event. METHODS: An anonymous electronic survey was created and sent to two populations: The Pediatric Anesthesia Leadership Council, a section of the Society for Pediatric Anesthesia, and the Pediatric Resuscitation Quality Collaborative, a multinational collaborative group, which works to improve resuscitation care in children. Standard summary and descriptive statistics were used for survey responses. RESULTS: The overall response rate was 41%. The majority of respondents worked in a university affiliated, free-standing children's hospital. Ninety-five percent of respondents had a dedicated pediatric MET at their hospital. In 60% of responses from Pediatric Resuscitation Quality Collaborative and 18% of Pediatric Anesthesia Leadership Council hospitals, the MET responds to pediatric intra-operative cardiac arrest; however, the majority of times MET involvement is requested rather than automatic. The MET was found to be activated intraoperatively for situations other than cardiac arrest such as, massive transfusion events, need for extra staff, and for specialty expertise. In 65% of institutions, simulation-based training for cardiac arrest is supported but lacking pediatric intra-operative focus. CONCLUSIONS: This survey revealed heterogeneity in the composition and response of the medical response teams responding to pediatric intra-operative cardiac arrests. Improved collaboration and cross training among MET, anesthesia, and operating room nursing may improve outcomes of pediatric intra-operative code events.

Implementation evaluation of a rapid response system in a regional emergency department: a dual-methods study using the behaviour change wheel.

BACKGROUND: Failure to recognise and respond to clinical deterioration is a major cause of high mortality events in emergency department (ED) patients. Whilst there is substantial evidence that rapid response teams reduce hospital mortality, unplanned intensive care admissions, and cardiac arrests on in-patient settings, the use of rapid response teams in the ED is variable with poor integration of care between emergency and specialty/intensive care teams. OBJECTIVES: The aim of this study was to evaluate uptake and impact of a rapid response system on recognising and responding to deteriorating patients in the ED and identify implementation factors and strategies to optimise future implementation success. METHODS: A dual-methods design was used to evaluate an ED Clinical Emergency Response System (EDCERS) protocol implemented at a regional Australian ED in June 2019. A documentation audit was conducted on patients eligible for the EDCERS during the first 3 months of implementation. Quantitative data from documentation audit were used to measure uptake and impact of the protocol on escalation and response to patient deterioration. Facilitators and barriers to the EDCERS uptake were identified via key stakeholder engagement and consultation. An implementation plan was developed using the Behaviour Change Wheel for future implementation. RESULTS: The EDCERS was activated in 42 (53.1%) of 79 eligible patients. The specialty care team were more likely to respond when the EDCERS was activated than when there was no activation ([n = 40, 50.6%] v [n = 26, 32.9%], p = 0.01). Six facilitators and nine barriers to protocol uptake were identified. Twenty behaviour change techniques were selected and informed the development of a theory-informed implementation plan. CONCLUSION: Implementation of the EDCERS protocol resulted in high response rates from specialty and intensive care staff. However, overall uptake of the protocol by emergency staff was poor. This study highlights the importance of understanding facilitators and barriers to uptake prior to implementing a new intervention.

Clinicians' use and perceptions of the pre-medical emergency team tier of one rapid response system: A mixed-methods study.

BACKGROUND: The pre-medical emergency team (pre-MET) tier of rapid response systems facilitates early recognition and treatment of deteriorating ward patients using ward-based clinicians before a MET review is needed. However, there is growing concern that the pre-MET tier is inconsistently used. OBJECTIVE: This study aimed to explore clinicians' use of the pre-MET tier. METHODS: A sequential mixed-methods design was used. Participants were clinicians (nurses, allied health, doctors) caring for patients on two wards of one Australian hospital. Observations and medical record audits were conducted to identify pre-MET events and examine clinicians' use of the pre-MET tier as per hospital policy. Clinician interviews expanded on understandings gained from observation data. Descriptive and thematic analyses were performed. RESULTS: Observations identified 27 pre-MET events for 24 patients that involved 37 clinicians (nurses = 24, speech pathologist = 1, doctors = 12). Nurses initiated assessments or interventions for 92.6% (n = 25/27) of pre-MET events; however, only 51.9% (n = 14/27) of pre-MET events were escalated to doctors. Doctors attended pre-MET reviews for 64.3% (n = 9/14) of escalated pre-MET events. Median time between escalation of care and in-person pre-MET review was 30 min (interquartile range: 8-36). Policy-specified clinical documentation was partially completed for 35.7% (n = 5/14) of escalated pre-MET events. Thirty-two interviews with 29 clinicians (nurses = 18, physiotherapists = 4, doctors = 7) culminated in three themes: Early Deterioration on a Spectrum, A Safety Net, and Demands Versus Resources. CONCLUSIONS: There were multiple gaps between pre-MET policy and clinicians' use of the pre-MET tier. To optimise use of the pre-MET tier, pre-MET policy must be critically reviewed and system-based barriers to recognising and responding to pre-MET deterioration addressed.

The patient experience of a medical emergency team review: A convergent mixed-methods study.

AIMS: The aim of this study was to explore clinician-patient engagement during, and patient experience of, medical emergency team (MET) reviews. DESIGN: This study involved a convergent mixed-methods design. METHODS: This three-phase study was conducted at two hospitals of one Australian health service. Reviews by the MET were observed for clinician-patient engagement behaviours; medical records were audited to confirm patient demographics and clinical characteristics; and patients who received a MET review were interviewed. Quantitative data were analysed using descriptive statistics, and thematic analysis of qualitative interview data was conducted. RESULTS: In total, 26 MET reviews were observed for 22 patients (median age = 81.5 years and 68.2% females). Between 8 and 13 clinicians and other staff members were present during each review, with a total of 209 clinicians present during the 26 reviews. Clinicians were not observed to speak directly or indirectly to the patient about their care in 38.5% (n = 10/26) of the MET reviews, and 58.3% (n = 56/96) of interventions were performed without explanation. Four themes were identified from the interviews: An unexpected event; A lack of understanding; In good hands, and What happens next? CONCLUSION: Clinician-patient engagement was infrequent during and after MET reviews. Patients experienced surprise from the sudden arrival of clinicians in their room and had poor levels of understanding about the review. However, most patients felt supported and safe. MET reviews are frequent safety-critical events, and this study identified the patient experience of these events. Clinicians should be aware that patients expressed they were surprised and shocked by the review and that an explanation of what was being done by the clinical team was rarely offered. These findings can be used to inform strategies to improve their patient-engagement behaviours and patient-centred care.

Mortality of patients with hospital-onset sepsis in hospitals with all-day and non-all-day rapid response teams: a prospective nationwide multicenter cohort study.

BACKGROUND: Hospital-onset sepsis is associated with a higher in-hospital mortality rate than community-onset sepsis. Many hospitals have implemented rapid response teams (RRTs) for early detection and timely management of at-risk hospitalized patients. However, the effectiveness of an all-day RRT over a non-all-day RRT in reducing the risk of in-hospital mortality in patient with hospital-onset sepsis is unclear. We aimed to determine the effect of the RRT's operating hours on in-hospital mortality in inpatient patients with sepsis. METHODS: We conducted a nationwide cohort study of adult patients with hospital-onset sepsis prospectively collected from the Korean Sepsis Alliance (KSA) Database from 16 tertiary referral or university-affiliated hospitals in South Korea between September of 2019 and February of 2020. RRT was implemented in 11 hospitals, of which 5 (45.5%) operated 24-h RRT (all-day RRT) and the remaining 6 (54.5%) had part-day RRT (non-all-day RRT). The primary outcome was in-hospital mortality between the two groups. RESULTS: Of the 405 patients with hospital-onset sepsis, 206 (50.9%) were admitted to hospitals operating all-day RRT, whereas 199 (49.1%) were hospitalized in hospitals with non-all-day RRT. A total of 73 of the 206 patients in the all-day group (35.4%) and 85 of the 199 patients in the non-all-day group (42.7%) died in the hospital (P = 0.133). After adjustments for co-variables, the implementation of all-day RRT was associated with a significant reduction in in-hospital mortality (adjusted odds ratio 0.57; 95% confidence interval 0.35-0.93; P = 0.024). CONCLUSIONS: In comparison with non-all-day RRTs, the availability of all-day RRTs was associated with reduced in-hospital mortality among patients with hospital-onset sepsis.

Intensive care unit trainee perception of end-of-life care provided during medical emergency team activation events.

BACKGROUND: Hospital medical emergency team (MET) activation events involving end-of-life care (EOLC) are common. The issues faced by medical staff attending these events are incompletely described. AIMS: The purpose of this study was to measure the perceptions of Victorian hospital medical staff, training in the speciality of intensive care, about multiple aspects of EOLC MET calls. We sought to determine the overall extent of formal training in MET and EOLC and assess the domains of self-perceived confidence, barriers to communication, frequency of clinician agreement and trainee distress. METHODS: We conducted an anonymous, voluntary, Internet-based survey of registered trainees of the College of Intensive Care Medicine of Australia and New Zealand in May 2019. The participants eligible were those trainees working in an adult intensive care unit in Victoria, Australia, during the study period. The main outcome measures were self-reported levels of confidence, barriers to communication, frequency of conflict and distress, senior support, supervision and access to training. RESULTS: Of 124 trainees surveyed, 75 (60%) responded. Overall, 78% of respondents felt confident to manage EOLC MET calls, but the frequently reported barriers to effective patient/next of kin communication included: (i) lack of private meeting rooms; (ii) resource and time constraints; and (iii) lack of patient and family availability during a MET call to discuss medical treatment limitations. Two-thirds of respondents reported emotional distress at least occasionally, this being frequent in one in five. Most (68%) trainees experienced conflict with other medical teams at least occasionally. Factors associated with experiencing distress at least occasionally include greater trainee age, patients' being unable to participate in discussion due to illness, resource and time constraints and negative encounters with other medical teams. CONCLUSIONS: Victorian intensive care trainees were confident managing EOLC MET activation events. However, distress was reported commonly and strategies are required to address the areas of concern.

Obstetric Emergencies Requiring Rapid Response Team Activation: A Retrospective Cohort Study in a High-Risk Tertiary Care Centre.

OBJECTIVE: The purpose of this study was to better understand obstetric codes requiring rapid response team activation by examining their incidence, indications, team response, and patient outcomes. METHODS: This was a retrospective study in peripartum women who required activation of the following codes during hospitalization between January 2014 and May 2018: "Code 77 (C77)" (obstetric emergency), "Code Blue (CB)" (cardiopulmonary compromise) or "Code Omega (CO)" (massive transfusion). Hospital database and health records were searched to identify and review cases. Data on code characteristics, resuscitative measures, and maternal and neonatal outcomes were collected. RESULTS: A total of 147 codes were identified during the study period (C77, 110; CO, 25; CB 12), with an overall incidence of 1 per 203 deliveries (C77, 1:271 deliveries, CO, 1:1194 deliveries; CB, 1:2488 deliveries). Common indications for C77 were cord prolapse (33%) and fetal bradycardia (32%), and for CO and CB, postpartum hemorrhage (84%) and cardiac arrest (42%), respectively. Most codes (67%) occurred after hours. The median decision-to-delivery interval was 8 (interquartile range 5-15) minutes after C77. Emergency cesarean delivery was performed for 57% of obstetric emergencies, and general anesthesia was administered in 63% of cesarean deliveries. Maternal and neonatal mortality rates were 0.68% and 7%, respectively. Major maternal morbidity was seen in 33% of cases. Debrief was documented for 4% of codes. CONCLUSION: Rapid response team activation was required more commonly in C77 than in CO or CB. Their response time and decision-to-delivery intervals were rapid. Mortality was low; however, one-third of parturients had major morbidities. We suggest closer patient monitoring, immediate availability of resources, and appropriate documentation and debriefing.

A clinical competence approach to examine British and Finnish nurses' attitudes towards the rapid response system model: A study in two acute hospitals.

BACKGROUND: Nurses' clinical competence involves an integration of knowledge, skills, attitudes, thinking ability, and values, which strongly affects how deteriorating patients are managed. OBJECTIVES: The aim of the study was to examine nurses' attitudes as part of clinical competence towards the rapid response system in two acute hospitals with different rapid response system models. METHODS: This is a comparative cross-sectional correlational study. A modified "Nurses' Attitudes Towards the Medical Emergency Team" tool was distributed among 388 medical and surgical registered nurses in one acute hospital in the UK and one in Finland. A total of 179 nurses responded. Statistical analyses, including exploratory factor analysis, Mann-Whitney U tests, Kruskal-Wallis tests, chi-square tests, and univariate and multivariate regression analyses, were used. FINDINGS: Generally, nurses had positive attitudes towards rapid response systems. British and Finnish nurses' attitudes towards rapid response system activation were divided when asked about facing a stable (normal vital signs) but worrisome patient. Finnish nurses relied more on intuition and were more likely to activate the rapid response system. Approximately half of the nurses perceived the physician's influence as a barrier to rapid response system activation. The only sociodemographic factor that was associated with nurses activating the rapid response system more freely was work experience ≥10 years. CONCLUSIONS: The findings are beneficial in raising awareness of nurses' attitudes and identifying attitudes that could act as facilitators or barriers in rapid response system activation. The study suggests that nurses' attitudes towards physician influence and intuition need to be improved through continuing development of clinical competence. When the system model included "worrisome" as one of the defined parameters for activation, nurses were more likely to activate the rapid response system. Future rapid response system models may need to have clear evidence-based instructions for nurses when they manage stable (normal vital signs) but worrisome patients and should acknowledge nurses' intuition and clinical judgement.

Evaluation of medical emergency team medication management practices in acute hospitals: A multicentre study.

BACKGROUND: Medical emergency teams use medications to rescue deteriorating patients. Medication management is the system of steps and processes, including prescribing, distribution, administration, and monitoring, to achieve the best outcomes from medication use. Systems or standards for medication management by medical emergency teams have not been defined. OBJECTIVES: The aim of the study was to propose potential solutions to improve medical emergency team medication management by evaluating medication supply and related medication management practices during medical emergency team activations and understanding clinicians' perceptions about medical emergency team medication management in acute hospitals. METHODS: A prospective multicentre audit of intensive care unit-equipped hospitals in Victoria, Australia, was conducted. After advertisement and invitation via scheduled email newsletters to hospitals, a representative of the medical emergency team from each hospital self-administered an online audit tool during December 2019 and January 2020. Audit data were analysed descriptively, and perceptions were analysed using content analysis. RESULTS: Responses were received from 32 of the 44 (72.7%) eligible hospitals. At 17 of the 32 (53.1%) hospitals, arrest trolleys provided medications for medical emergency team activations, in addition to arrest calls. At 15 of the 32 (46.9%) hospitals, separate, dedicated medical emergency team medication supplies were used to care for deteriorating patients. Dedicated medical emergency team supplies contained a median of 20 (range = 8-37) medications, predominantly cardiovascular (median = 8, mode = 7, range = 4-16) and neurological medications (median and mode = 6, range = 0-11). Variation was observed in all storage and other supply-related medication management practices studied. The four most frequent categories of clinicians' perceptions described systematic challenges with availability of the right medication in the right place at the right time. CONCLUSIONS: Current supply and related medication management practices and clinicians' perceptions demonstrated further development is necessary for medication management to meet the needs of medical emergency team clinicians and their patients.

Part 7: Systems of Care: 2020 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care.

Survival after cardiac arrest requires an integrated system of people, training, equipment, and organizations working together to achieve a common goal. Part 7 of the 2020 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care focuses on systems of care, with an emphasis on elements that are relevant to a broad range of resuscitation situations. Previous systems of care guidelines have identified a Chain of Survival, beginning with prevention and early identification of cardiac arrest and proceeding through resuscitation to post-cardiac arrest care. This concept is reinforced by the addition of recovery as an important stage in cardiac arrest survival. Debriefing and other quality improvement strategies were previously mentioned and are now emphasized. Specific to out-of-hospital cardiac arrest, this Part contains recommendations about community initiatives to promote cardiac arrest recognition, cardiopulmonary resuscitation, public access defibrillation, mobile phone technologies to summon first responders, and an enhanced role for emergency telecommunicators. Germane to in-hospital cardiac arrest are recommendations about the recognition and stabilization of hospital patients at risk for developing cardiac arrest. This Part also includes recommendations about clinical debriefing, transport to specialized cardiac arrest centers, organ donation, and performance measurement across the continuum of resuscitation situations.

The association between hospital length of stay before rapid response system activation and clinical outcomes: a retrospective multicenter cohort study.

BACKGROUND: Rapid response system (RRS) is being increasingly adopted to improve patient safety in hospitals worldwide. However, predictors of survival outcome after RRS activation because of unexpected clinical deterioration are not well defined. We investigated whether hospital length of stay (LOS) before RRS activation can predict the clinical outcomes. METHODS: Using a nationwide multicenter RRS database, we identified patients for whom RRS was activated during hospitalization at 9 tertiary referral hospitals in South Korea between January 1, 2016, and December 31, 2017. All information on patient characteristics, RRS activation, and clinical outcomes were retrospectively collected by reviewing patient medical records at each center. Patients were categorized into two groups according to their hospital LOS before RRS activation: early deterioration (LOS < 5 days) and late deterioration (LOS ≥ 5 days). The primary outcome was 28-day mortality and multivariable logistic regression was used to compare the two groups. In addition, propensity score-matched analysis was used to minimize the effects of confounding factors. RESULTS: Among 11,612 patients, 5779 and 5883 patients belonged to the early and late deterioration groups, respectively. Patients in the late deterioration group were more likely to have malignant disease and to be more severely ill at the time of RRS activation. After adjusting for confounding factors, the late deterioration group had higher 28-day mortality (aOR 1.60, 95% CI 1.44-1.77). Other clinical outcomes (in-hospital mortality and hospital LOS after RRS activation) were worse in the late deterioration group as well, and similar results were found in the propensity score-matched analysis (aOR for 28-day mortality 1.66, 95% CI 1.45-1.91). CONCLUSIONS: Patients who stayed longer in the hospital before RRS activation had worse clinical outcomes. During the RRS team review of patients, hospital LOS before RRS activation should be considered as a predictor of future outcome.

Increased time from physiological derangement to critical care admission associates with mortality.

BACKGROUND: Rapid response systems aim to achieve a timely response to the deteriorating patient; however, the existing literature varies on whether timing of escalation directly affects patient outcomes. Prior studies have been limited to using 'decision to admit' to critical care, or arrival in the emergency department as 'time zero', rather than the onset of physiological deterioration. The aim of this study is to establish if duration of abnormal physiology prior to critical care admission ['Score to Door' (STD) time] impacts on patient outcomes. METHODS: A retrospective cross-sectional analysis of data from pooled electronic medical records from a multi-site academic hospital was performed. All unplanned adult admissions to critical care from the ward with persistent physiological derangement [defined as sustained high National Early Warning Score (NEWS) > / = 7 that did not decrease below 5] were eligible for inclusion. The primary outcome was critical care mortality. Secondary outcomes were length of critical care admission and hospital mortality. The impact of STD time was adjusted for patient factors (demographics, sickness severity, frailty, and co-morbidity) and logistic factors (timing of high NEWS, and out of hours status) utilising logistic and linear regression models. RESULTS: Six hundred and thirty-two patients were included over the 4-year study period, 16.3% died in critical care. STD time demonstrated a small but significant association with critical care mortality [adjusted odds ratio of 1.02 (95% CI 1.0-1.04, p = 0.01)]. It was also associated with hospital mortality (adjusted OR 1.02, 95% CI 1.0-1.04, p = 0.026), and critical care length of stay. Each hour from onset of physiological derangement increased critical care length of stay by 1.2%. STD time was influenced by the initial NEWS, but not by logistic factors such as out-of-hours status, or pre-existing patient factors such as co-morbidity or frailty. CONCLUSION: In a strictly defined population of high NEWS patients, the time from onset of sustained physiological derangement to critical care admission was associated with increased critical care and hospital mortality. If corroborated in further studies, this cohort definition could be utilised alongside the 'Score to Door' concept as a clinical indicator within rapid response systems.

Medical emergency team training: needs assessment, feedback and learning objectives.

BACKGROUND: There are no published studies assessing learning needs and attitudes prior to attending a medical emergency team (MET) education programme. AIMS: To conduct a learning needs assessment of MET education programme participants to assess what technical and non-technical skills should be incorporated. METHODS: All participants in a MET education programme over a 12-month period were invited to complete a self-administered electronic survey. Participants were ICU team members (intensive care registrars and nurses) and medical registrars. Responses were captured through a 5-point Likert scale. RESULTS: There were 62 responses out of 112 participants (55% response rate). Most participants either agreed or strongly agreed that MET training was valuable (59 respondents) and should be multidisciplinary (61 respondents). ICU team members were more likely to select 'Management of End-of-Life Care' (72% compared with only 16% of medical registrars, P < 0.05) as an important learning objective. Non-technical skills such as 'Task Management' (67% compared with 37%, P < 0.05) and 'Team Communication' (79% compared with 32%, P < 0.05) were also more likely to be selected by ICU team members. Nursing team members were more likely to select 'Approach to Common MET Calls' (100% compared with 50% of medical team members, P < 0.05). CONCLUSIONS: MET education programme participants overwhelmingly feel that training should be multidisciplinary. However, there are disparities between the perceived learning needs of medical and nursing personnel, and between intensive care team members and medical registrars, which may impact on the design and implementation of a multidisciplinary education programme.

Pharmacist perceptions of CliftonStrengths® themes important for success in advanced cardiovascular life support.

WHAT IS KNOWN AND OBJECTIVE: Advanced Cardiovascular Life Support (ACLS) is an integrated, team-based approach to optimizing patient outcomes during acute cardiovascular events. Due to the fast-paced, high-stress environment, inherent strengths may impact performance and confidence with ACLS skills. The objective of this study was to assess pharmacist perceptions regarding strengths deemed important during emergency cardiovascular response. METHODS: An electronic survey was administered to members of the American College of Clinical Pharmacists Critical Care, Cardiology, Internal Medicine, Emergency Medicine and Pediatrics Practice and Research Network listservs. The survey assessed the top 5 strengths deemed important for being part of an emergency response team, a pharmacist's role in ACLS and a team leader's role in ACLS. The primary outcome was top strengths required for pharmacist involvement in ACLS. Descriptive statistics were used to present survey results. RESULTS: Of the 359 responses included, nearly all respondents had been certified by the American Heart Association in ACLS and/or Pediatric Advanced Life Support (PALS). The top CliftonStrengths® themes considered important for a pharmacist's role in ACLS were communication, adaptability, analytical, focus and responsibility. The top CliftonStrengths® themes considered important for the team leader's role in ACLS were communication, command, analytical, focus and adaptability. The top CliftonStrengths® themes important for an emergency response team were communication, adaptability, focus, analytical and command. WHAT IS NEW AND CONCLUSIONS: By determining the personality traits perceived to be associated with high performance in ACLS, approaches can be taken to personalize student learning in order to train "practice-ready" pharmacists that can be integral members of the ACLS team.

Dealing with the impact of the COVID-19 pandemic on a rapid response team operation in Brazil: Quality in practice.

QUALITY PROBLEM OR ISSUE: Up to 13 July 2020, >12 million laboratory-confirmed cases of coronavirus disease of 2019 (COVID-19) infection have been reported worldwide, 1 864 681 in Brazil. We aimed to assess an intervention to deal with the impact of the COVID-19 pandemic on the operations of a rapid response team (RRT). INITIAL ASSESSMENT: An observational study with medical record review was carried out at a large tertiary care hospital in Fortaleza, a 400-bed quaternary hospital, 96 of which are intensive care unit beds. All adult patients admitted to hospital wards, treated by the RRTs during the study period, were included, and a total of 15 461 RRT calls were analyzed. CHOICE OF SOLUTION: Adequacy of workforce sizing. IMPLEMENTATION: The hospital adjusted the size of its RRTs during the period, going from two to four simultaneous on-duty medical professionals. EVALUATION: After the beginning of the pandemic, the number of treated cases in general went from an average of 30.6 daily calls to 79.2, whereas the extremely critical cases went from 3.5 to 22 on average. In percentages, the extremely critical care cases went from 10.47 to 20%, with P < 0.001. Patient mortality remained unchanged. The number of critically ill cases and the number of treated patients increased 2-fold in relation to the prepandemic period, but the effectiveness of the RRT in relation to mortality was not affected. LESSONS LEARNED: The observation of these data is important for hospital managers to adjust the size of their RRTs according to the new scenario, aiming to maintain the intervention effectiveness.

Rapid Response System Should Be Enhanced at Non-general Ward Locations: a Retrospective Multicenter Cohort Study in Korea.

BACKGROUND: A rapid response system (RRS) contributes to the safety of hospitalized patients. Clinical deterioration may occur in the general ward (GW) or in non-GW locations such as radiology or dialysis units. However, there are few studies regarding RRS activation in non-GW locations. This study aimed to compare the clinical characteristics and outcomes of patients with RRS activation in non-GW locations and in the GW. METHODS: From January 2016 to December 2017, all patients requiring RRS activation in nine South Korean hospitals were retrospectively enrolled and classified according to RRS activation location: GW vs non-GW RRS activations. RESULTS: In total, 12,793 patients were enrolled; 222 (1.7%) were non-GW RRS activations. There were more instances of shock (11.6% vs. 18.5%) and cardiac arrest (2.7% vs. 22.5%) in non-GW RRS activation patients. These patients also had a lower oxygen saturation (92.6% ± 8.6% vs. 88.7% ± 14.3%, P < 0.001) and a higher National Early Warning Score 2 (7.5 ± 3.4 vs. 8.9 ± 3.8, P < 0.001) than GW RRS activation patients. Although non-GW RRS activation patients received more intubation (odds ratio [OR], 3.135; P < 0.001), advanced cardiovascular life support (OR, 3.912; P < 0.001), and intensive care unit transfer (OR, 2.502; P < 0.001), their hospital mortality (hazard ratio, 0.630; P = 0.013) was lower than GW RRS activation patients upon multivariate analysis. CONCLUSION: Considering that there were more critically ill but recoverable cases in non-GW locations, active RRS involvement should be required in such locations.

Etiology and Timing of Postoperative Rapid Response Team Activations.

In this retrospective cohort study we sought to evaluate the association between the etiology and timing of rapid response team (RRT) activations in postoperative patients at a tertiary care hospital in the southeastern United States. From 2010 to 2016, there were 2,390 adult surgical inpatients with RRT activations within seven days of surgery. Using multivariable linear regression, we modeled the correlation between etiology of RRT and timing of the RRT call, as measured from the conclusion of the surgical procedure. We found that respiratory triggers were associated with an increase in time after surgical procedure to RRT of 10.6 h compared to activations due to general concern (95% CI 3.9 - 17.3) (p = 0.002). These findings may have an impact on monitoring of postoperative patients, as well as focusing interventions to better respond to clinically deteriorating patients.

[Role of ski injury treatment system between the ski resort medical station of Winter Olympics and the nearby medical care hospital].

OBJECTIVE: To make a retrospective analysis of the situation and process of treating skiers' injuries in the medical station of the Wanlong ski resort in Chongli and the nearest treatment hospital, and to provide a basis for the establishment and optimization of the treatment process between the medical station of the Winter Olympics ski resort and the nearest treatment hospital, and to gain experience for medical security of mass skiing. METHODS: The data of all ski injuries in Chongli District were collected from the medical station of the Wanlong ski resort during the 2018-2019 snow season (November 2018 to April 2019) and the nearest treatment hospital during two periods (March 2019, and November 2019 to January 2020). The differences of injury causes, injury types, injury sites, and treatment effects of the injured skiers were analyzed. RESULTS: A total of 755 cases of ski injuries were recorded in the medical station of Wanlong ski resort, the estimated incidence of injury was 2.02‰ per day. The nearest treatment hospital treated a total of 838 injured skiers from different ski resorts in Chongli District in the two periods. In the records of the ski resort medical station, the main causes of injury were technical defects and turnovers (53.6%). Knee joint injury rate was the highest (18.7%), followed by head and neck (12.9%) and lower limb (11.9%). The number of injuries on intermediate roads was the highest (40.0%), the greatest number of injuries (81.2%) occurred when the age of skiing was less than 5 years. In the records of the nearest treatment hospital, the injury types were fracture or fissure fracture, contusion and trauma, and muscle and soft tissue injury, accounting for 30.5%, 27.4%, and 21.2% respectively. 9.6% of the injured took the snow field ambulance to the hospital, and 50% of them suffered from fractures or fissure fractures. CONCLUSION: The injury rate of skiing in the 2018-2019 snow season of the Wanlong ski resort in Chongli was higher than that reported by foreign literature. Severe trauma (including severe fractures and concussions) could occur and patients needed to be transferred to the nearest hospital for treatment. The ski resort medical station and the nearest treatment hospital should be strengthened with adequate medical staff and equipment, and promote cooperation in the timely referral of seriously injured patients, the organization and construction of ski patrols and the medical security of large-scale competitions, thus playing an important role in forming a grassroots network of medical security and treatment system for skiing.

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

BACKGROUND: Medical emergency team (MET) activation criteria are sometimes modified to minimise unnecessary MET calls in patients who have chronic physiological derangements, have limitation of medical treatment orders in place, or have recently received treatment for clinical deterioration. However, the safety implications of modifying MET activation criteria are poorly understood. OBJECTIVES: The aim of the study was to examine the safety of modifying MET activation criteria. Specifically, we aimed to examine the frequency and nature of modifications to MET activation criteria and compare characteristics and outcomes of patients with and without modifications to MET activation criteria. METHODS: This was a point prevalence study using a retrospective medical record audit. Patients admitted to 14 wards on November 7, 2018, at two acute-care hospitals of one health service in Melbourne, Australia, were included (N = 430). Data were analysed using descriptive and inferential statistics. The main outcome measures included frequency and nature of modifications to MET activation criteria on a specified date, MET calls, intensive care unit admission, in-hospital cardiac arrest, and in-hospital death. RESULTS: Amongst 430 inpatients, there were 30 modifications to MET activation criteria in 26 (6.0%) patients. All modifications were intended to trigger METs at more extreme levels of physiological derangement. Most modifications pertained to tachypnoea (26.7%; n = 8/30) and bradycardia (23.3%; n = 7/30). Patients with modifications were more likely to have documented physiological deterioration that fulfilled MET (47.8%, n = 11; p < 0.001) or pre-MET (87.0%, n = 20; p < 0.001) criteria in the preceding 24-h period than patients without modifications. Of patients with modifications, none were admitted to an intensive care unit, had a cardiac arrest, or died in the hospital. There were no differences in hospital length of stay or discharge destination between patients with and without modifications. CONCLUSIONS: In this point prevalence study, modifications to MET activation criteria were infrequent and not associated with negative patient safety outcomes.

Understanding the pre-medical emergency team tier of a mature rapid response system: A content analysis of guidance documents.

BACKGROUND: The pre-medical emergency team (pre-MET) tier of rapid response systems (RRSs) includes extended activation criteria to identify earlier clinical deterioration and a ward-based patient review that is undertaken by the affected patient's admitting team or covering doctors. There is limited understanding of the structure and processes of the pre-MET RRS tier that are expected to guide clinicians' actions and subsequent patient safety outcomes. OBJECTIVE: The aim of the study was to describe the structure and processes of the pre-MET RRS tier in one acute care setting. METHODS: An exploratory descriptive design involving document analysis was used. Guidance documents (policies, procedures, guidelines, charts, educational materials) were obtained from one health service with a mature, multitiered RRS in Melbourne, Australia. Documents were analysed using content analysis. Concept- and data-driven approaches were used to construct a coding frame. RESULTS: Nineteen guidance documents supporting the pre-MET RRS tier on general wards were analysed. The coding frame consisted of seven main categories: Defining the Pre-MET RRS Tier, Essential Resources for Operationalisation, Recognising Pre-MET Events, Pathways for Activation, Exceptions to the Rule, Clinician Responses to Pre-MET Events, and Recording Pre-MET Events. The structures and processes of the pre-MET RRS tier were largely consistent with national guidelines, but there were internal inconsistencies in pre-MET activation criteria and unclear recommendations for modifying criteria. Pathways for activating the pre-MET RRS tier were complex and involved many steps, including validation processes before escalation of care to doctors. Responses to pre-MET events were seldom aligned to specific clinician types or groups, with nurses and allied health clinicians being under-represented. CONCLUSIONS: We identified opportunities to improve guidance documents supporting the pre-MET RRS tier that may assist other health services engaged in planning or evaluating pre-MET strategies. Further research is needed to understand clinicians' use of the pre-MET RRS tier to inform targeted strategies to optimise its design and implementation.
