Background The rapid response system has been implemented in many hospitals worldwide and, reportedly, the timing of medical emergency team (MET) attendance in relation to the duration of hospitalization is associated with the mortality of MET patients. We evaluated the relationship between duration of hospitalization before MET activation and patient mortality. We compared cases of MET activation for early, intermediate, and late deterioration to patient characteristics, activation characteristics, and patient outcomes. We also aimed to determine the relationship, after adjusting for confounders, between the duration of hospitalization before MET activation and patient mortality. Materials and methods We retrospectively evaluated patients who triggered MET activation in general wards from March 2009 to February 2015 at the Asan Medical Center in Seoul. Patients were categorized as those with early deterioration (less than 2 days after admission), intermediate deterioration (2–7 days after admission), and late deterioration (more than 7 days after admission) and compared them to patient characteristics, activation characteristics, and patient outcomes. Results Overall, 7114 patients were included. Of these, 1793 (25.2%) showed early deterioration, 2113 (29.7%) showed intermediate deterioration, and 3208 (45.1%) showed late deterioration. Etiologies of MET activation were similar among these groups. The clinical outcomes significantly differed among the groups (intensive care unit transfer: 34.1%, 35.6%, and 40.4%; p < 0.001 and mortality: 26.3%, 31.5%, and 41.2%; p < 0.001 for early, intermediate, and late deterioration, respectively). Compared with early deterioration and adjusted for confounders, the odds ratio of mortality for late deterioration was 1.68 (1.46–1.93). Conclusions Nearly 50% of the acute clinically-deteriorating patients who activated the MET had been hospitalized for more than 7 days. Furthermore, they presented with higher rates of mortality and ICU transfer than patients admitted for less than 7 days before MET activation and had mortality as an independent risk factor.

Introduction: To determine the association between both abnormal individual vital signs and abnormal vital sign groups in the emergency department, and undesirable patient outcomes: hospital admission, medical emergency team calls and death. Method: We undertook a prospective cohort study in a tertiary referral emergency department (February–May 2015). Vital signs were collected prospectively in the emergency department and undesirable outcomes from the medical records. The primary outcomes were undesirable outcomes for individual vital signs (multivariate logistic regression) and vital sign groups (univariate analyses). Results: Data from 1438 patients were analysed. Admission was associated with tachycardia, tachypnoea, fever, ≥1 abnormal vital sign on admission to the emergency department, ≥1 abnormal vital sign at any time in the emergency department, a persistently abnormal vital sign, and vital signs consistent with both sepsis (tachycardia/hypotension/abnormal temperature) and pneumonia (tachypnoea/fever) (p < 0.05). Medical emergency team calls were associated with tachycardia, tachypnoea, ≥1 abnormal vital sign on admission (odds ratio: 2.3, 95% confidence interval: 1.4–3.8), ≥2 abnormal vital signs at any time (odds ratio: 2.4, 95% confidence interval: 1.2–4.7), and a persistently abnormal vital sign (odds ratio: 2.7, 95% confidence interval: 1.6–4.6). Death was associated with Glasgow Coma Score ≤13 (odds ratio: 6.3, 95% confidence interval: 2.5–16.0), ≥1 abnormal vital sign on admission (odds ratio: 2.6, 95% confidence interval: 1.2–5.6), ≥2 abnormal vital signs at any time (odds ratio: 6.4, 95% confidence interval: 1.4–29.5), a persistently abnormal vital sign (odds ratio: 4.3, 95% confidence interval: 2.0–9.0), and vital signs consistent with pneumonia (odds ratio: 5.3, 95% confidence interval: 1.9–14.8). Conclusion: Abnormal vital sign groups are generally superior to individual vital signs in predicting undesirable outcomes. They could inform best practice management, emergency department disposition, and communication with the patient and family.

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.

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&lt;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.

Objective. This study examined the hypothesis that correlations exist between the carbon monoxide exposure time and the carboxyhemoglobin concentration at the site of carbon monoxide poisoning, using a pulse carbon monoxide oximeter in rural areas or the carboxyhemoglobin concentration measured at a given medical institution.Background. In previous studies, no definitive relationships between the arterial blood carboxyhemoglobin level and the severity of carbon monoxide poisoning have been observed.Method. The subjects included patients treated for acute carbon monoxide poisoning in whom a medical emergency team was able to measure the carboxyhemoglobin level at the site of poisoning. We examined the relationship between the carboxyhemoglobin level at the site of poisoning and carbon monoxide exposure time and the relationships between the arterial blood carboxyhemoglobin level and carbon monoxide exposure time.Results. A total of 10 patients met the above criteria. The carboxyhemoglobin levels at the site of poisoning were significantly and positively correlated with the exposure time (rs = 0.710,p=0.021), but the arterial blood carboxyhemoglobin levels were not correlated with the exposure time.Conclusion. In rural areas, the carboxyhemoglobin level measured at the site of carbon monoxide poisoning correlated with the exposure time.
