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.

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.

Healthcare Improvement

Introduction: The institute for Healthcare Improvement (IHI) encouraged the implementation of rapid response teams (RRT) in hospitals with the aim of early detection of patient deterioration. The rapid response system (formerly Medical Emergency Team (MET)) has been in place at our institution since 2005; however, data regarding its utilization and outcomes are scarce. Methods: Data regarding patient characteristics and reasons for activating RRTs were collected from hospital telephone operator records and patient medical records. The study was IRB exempt. Results: During a 2 month period (08/09/16 to 10/09/16), the RRT was activated 96 times on 93 patients. Of those, 31 RRT activations (32%) took place within 24 hours of admission to the hospital. The average age of these patients was 64, and 59% were male. Fifty-four RRT activations (56%) were called during the daytime shift (from 7 am to 7 pm). The reason for calling the RRT was mentioned in the hospital operators paging message in 67/96 cases. The most common reasons for activating the system were: Respiratory distress 34/67 (51%), mental status changes 9/67 (13%), and tachycardia 9/67 (13%). Other less common causes were seizures 3/67 (4.5%), chest pain 3/67 (4.5%), hypotension 3/67 (4.5%), and falls 2/67 (3%). Twenty patients (22%) on whom an RRT was called, died during the same hospital admission. The mortality rate of those patients was 6 folds higher than the general In-hospital mortality rate. The average age of the patients who died was 63. Respiratory distress was the most common cause of RRT activation among patients who died 10/20 (50%). Conclusion: Patients admitted to the hospital who had an RRT activation had a six fold risk of dying during the same admission. The majority of RRT activations were for respiratory distress, mental status changes, and tachycardia, and one-third occurred within the first 24 hours of admission. Routine review of RRT data can help target areas for improvement, specifically, factors contributing to in-hospital mortality.

The Impact

Objective To assess the impact of a regional rapid response system (RRS) implemented in a Chinese Joint Commission International Hospital on the timely treatment of patients with serious adverse events (SAEs). Methods Clinical SAEs, activation periods, reasons for RSS activation, and patient outcomes were assessed using SAE response sheets at admission to the hospital and over 31 months of follow-up. Results We found that 192 events were called by medical staff and 6 were called by auxiliary staff. Reasons for the 385 RRS activations included: unconsciousness (133; 34.5%), and airway obstruction and absent carotid pulse (49 each; 12.7%). The average arrival time of the medical emergency team was 2.4 ± 0.1 minutes. There were 123 (62.1%) RRS activations during daytime working hours (8:00–17:00); CPR was performed in 86 (43.4%) cases. Outcomes of RRS were: vital signs stabilized in 82 (41.4%) patients and 61 (30.8%) patients were transferred to ICU. Conclusion Our experience showed that the regional RRS has led to better integrated multidisciplinary cooperation and reduced time for treating patients with SAEs, resulting in success of the RRS.

Levels Of Care

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.

The Right

Introduction: An average of 1500 medical emergencies are called to the operators each month for the main campus Cleveland Clinic. Acronyms can help the employee to remember necessary information to quickly and accurately activate the right medical emergency team in a short time. We developed the acronym LEAN (L-Location, E-Event Type; code or rapid response, A-Adult or Child, N-Call back number). We reduced the length of the call which led to the prompt activation of the medical emergency team. Hypothesis: We hypothesized that this quality improvement initiative, using the LEAN acronym would: 1. Reduce length of call time to the operator and 2. Lead to increased event survival of event for patients who have had a life-threatening medical emergency. Methods: The LEAN acronym was implemented in 2016 by sharing this acronym at staff meetings, and daily huddles. We developed an operator scorecard which tracked the average call time to the 111 (code) and 122 (rapid response) operator lines before and after LEAN implementation. We used our AHA Get With The Guidelines-Resuscitation® data to determine cardiopulmonary arrest (CPA) event survival. Results: Since August of 2016 we have reduced our 122 rapid response calls by 30 seconds and our 111 code calls by 12 seconds. CPA survival rates were 73% (437 of 599) in 2015 and 78.9% (548 of 703) in 2017, for an 8.1% increase ( Figure 1 ). While there is not a statistically significant ( p = 0.511) difference between time periods when we look at percentage of lives saved, the number of lives saved increased. This is a clinically important difference because more people survived. We plan to continue to disseminate LEAN and work to improve response time. Conclusion: Since we introduced LEAN there has been a reduction in the time to activation of our medical emergency teams and an 8% increase in our GWTG-R® Cardiopulmonary Arrest event survival. Lives were saved and LEAN may have played a role in this clinically important difference.
