Response System

Objectives The aim of the present study was to determine whether changing a hospital rapid response system (RRS) from a two-tiered to a three-tiered model can reduce disruption to normal hospital routines while maintaining the same overall patient outcomes. Methods Staff at an Australian teaching hospital attending medical emergency team and cardiac arrest (MET/CA) calls were interviewed after the RRS was changed from a two-tiered to three-tiered model, and the results were compared with a study using the same methods conducted before the change. The main outcome measures were changes in: (1) the incident rate resulting from staff leaving normal duties to attend MET/CA calls; (2) the cardiac arrest rate, (3) unplanned intensive care unit (ICU) admission rates; and (4) hospital mortality. Results We completed 1337 structured interviews (overall response rate 65.2%). The rate of incidents occurring as a result of staff leaving normal duties to attend MET/CA calls fell from 213.7 to 161.3 incidents per 1000 MET/CA call participant attendances (P<0.001), but the rate of cardiac arrest and unplanned ICU admissions did not change significantly. Hospital mortality was confounded by the opening of a new palliative care ward. Conclusion A three-tiered RRS may reduce disruption to normal hospital routines while maintaining the same overall patient outcomes. What is known about the topic? RRS calls result in significant disruption to normal hospital routines because staff can be called away from normal duties to attend. The best staffing model for an RRS is currently unknown. What does this paper add? The present study demonstrates, for the first time, that changing a hospital RRS from a two-tiered to a three-tiered model can reduce the rate of incidents reported by staff caused by leaving normal duties to attend RRS calls while maintaining the same overall patient outcomes. What are the implications for practitioners? Hospitals could potentially reduce disruption to normal hospital routines, without compromising patient care, by changing to a three-tiered RRS.

Background According to the rapid response system’s team composition, responding teams were named as rapid response team (RRT), medical emergency team (MET), and critical care outreach. A RRT is often a nurse-led team, whereas a MET is a physician-led team that mainly plays the role of an efferent limb. As few multicenter studies have focused on physician-led METs, we comprehensively analyzed cases for which physician-led METs were activated. Methods We retrospectively analyzed cases for which METs were activated. The study population consisted of subjects over 18 years of age who were admitted in the general ward from January 2016 to December 2017 in 9 tertiary teaching hospitals in Korea. The data on subjects’ characteristics, activation causes, activation methods, performed interventions, in-hospital mortality, and intensive care unit (ICU) transfer after MET activation were collected and analyzed. Results In this study, 12,767 cases were analyzed, excluding those without in-hospital mortality data. The subjects’ median age was 67 years, and 70.4% of them were admitted to the medical department. The most common cause of MET activation was respiratory distress (35.1%), followed by shock (11.8%), and the most common underlying disease was solid cancer (39%). In 7,561 subjects (59.2%), the MET was activated using the screening system. The commonly performed procedures were arterial line insertion (17.9%), intubation (13.3%), and portable ultrasonography (13.0%). Subsequently, 29.4% of the subjects were transferred to the ICU, and 27.2% died during hospitalization. Conclusions This physician-led MET cohort showed relatively high rates of intervention, including arterial line insertion and portable ultrasonography, and low ICU transfer rates. We presume that MET detects deteriorating patients earlier using a screening system and begins ICU-level management at the patient’s bedside without delay, eventually preventing the patient’s condition from worsening and transfer to the ICU.

Introduction. In relation to pre-hospital treatment of patients with cardiac arrest (CA) in the field where resuscitation is often started by nonprofessionals, resuscitation in hospital is most commonly performed by well-trained personnel. Objective. The aim was to define the factors associated with an improved outcome among patients suffering from the inhospital CA (IHCA). Methods. The prospective study included a total of 100 patients in the Emergency Center over two-year period. The patterns by the Utstein-Style guidelines recorded the following: age, sex, reason for hospital admission, comorbidity, cause and origin of CA, continuous monitoring, time of arrival of the medical emergency team and time of delivery of the first defibrillation shock (DC). Results. Most patients (61%) had cardiac etiology. Return of spontaneous circulation (ROSC) was achieved in 58% of patients. ROSC was more frequently achieved in younger patients (57.69?11.37), (p<0.05), non-surgical patients (76.1%), (p<0.01) and in patients who were in continuous monitoring (66.7%) (p<0.05). The outcome of CPR was significantly better in patients who received advanced life support (ALS) (76.6%) (p<0.01). Time until the delivery of the first DC shock was significantly shorter in patients who achieved ROSC (1.67?1.13 min), (p<0.01). A total of 5% of IHCA patients survived to hospital discharge. Conclusion. In our study, the outcome of CPR was better in patients who were younger and with non-surgical diseases, which are prognostic factors that we cannot control. Factors associated with better outcome of IHCA patients were: continuous monitoring, shorter time until the delivery of the first DC and ALS. This means that better education of medical staff, better organization and up-to-dated technical equipment are needed.

Introduction: There is a paucity of data regarding the association of pediatric patient characteristics with hospital mortality and transfer to higher levels of care following medical emergency team (MET) events. Objective: To explore associations of patient characteristics with hospital mortality and transfer to higher levels of care among pediatric patients who experienced a MET event during an admission. Methods: This retrospective observational study included data from patients aged ≤17 years admitted to an urban, tertiary hospital who experienced a MET event between 2014 and 2017. Data specific to the initial MET event for a patient were included for analysis. Multiple logistic regression models were used to test associations between patient characteristics (age, race, sex, ethnicity, timing of MET event, primary admission diagnosis, receiving care on specialized units) and each outcome separately. Results: Of the 366 patients eligible for inclusion, 11% (41 of 366) experienced hospital mortality, and 59% (216 of 366) were transferred to higher levels of care following MET events. Hospital mortality was lower among those who received emergency department care within 24 hours before the MET event compared to patients who did not (OR=0.17; 95% CI=0.04-0.82). Hospital mortality was higher among those with cardiac-related primary admission diagnoses compared to patients with noncardiac-related diagnoses (OR=3.44; 95% CI=1.04-11.39), and among those of unknown race compared to white patients (OR=3.14; 95% CI=1.17-8.48). No patient characteristics were associated with transfers to higher levels of care. Conclusions: While MET events may cause concern about failures to triage patients to appropriate levels of care upon admission, we observed that patients admitted from the emergency department within 24 hours before their MET event were more likely to survive to discharge. Higher hospital mortality following MET events was observed among patients with cardiac diagnoses and those of unknown race; more research is needed to understand how processes and documentation of care are related to these patients. Further study of how these characteristics and other potential confounding factors are associated with MET events and outcomes is warranted.

Hospital Cardiac Arrest

Background: Prior studies of Medical Emergency Teams (METs) in pediatric hospitals have shown inconsistent results in terms of their ability to improve outcomes. Whether the variable success is due to differential utilization of METs among hospitals is unknown. Methods: Within the Get With The Guidelines-Resuscitation Registry (GWTG-R), we identified children (age <18 years) with an in-hospital cardiac arrest (IHCA) on the general inpatient or telemetry floors from 2007 to 2014. In cases of IHCA where MET evaluation did not occur, we examined the frequency of “missed” opportunities for activation of the MET based upon the presence of one or more abnormal vital signs. We also examined the variability in utilization of the MET among those hospitals with at least ten cases of IHCA. Results: Of 215 children from 23 hospitals sustaining an IHCA, 48 (22.3%) had a preceding MET evaluation. Children with MET evaluation prior to IHCA were older (6.8 ± 6.5 vs. 3.1 ± 4.7, p < 0.001) and were more likely to have metabolic/electrolyte abnormalities (9/48 [18.8%] vs. 9/167 [5.4%], p=0.006), sepsis (8/48 [16.7%] vs. 8/167 [4.8%], p=0.01), or malignancy (11/48 [22.9%] vs. 9/167 [5.4%], p<0.001) at the time of their IHCA. Hospital utilization of the MET varied substantially (median 20%; inter-quartile range [IQR]: 3.4%-29.8%; range: 0%-36.4%). Among patients who did not have a MET called prior to their IHCA, 78/141 (55.3%) had at least one abnormal vital sign that should have triggered a MET. Conclusion: In a large, national registry, we found that the majority of pediatric IHCA cases are not preceded by a MET evaluation despite meeting criteria that should have triggered a MET. Improved utilization of the MET by all hospitals could lead to fewer pediatric IHCA and improved outcomes following pediatric IHCA.
