This study aimed to retrospectively examine patients evaluated by the Code Blue team on a Code Blue call in our hospital between 2016-2017. Primary outcome: an examination of the survival rates and demographic data of the patients evaluated as an emergency by a Code Blue call in the period 2016-2017. Secondary outcome: to determine the rates of false Code Blue calls, the clinics giving Code Blue calls and the relationship between the times of Code Blue calls and mortality.
The overall goal of the project is to reduce the number of unexpected patient deteriorations by 50% at Emergency Departments (ED) by investigating if the novel Patient Deterioration Warning Systems (PDWS), can improve clinicians' ability to identify deterioration at an earlier stage. A third of all acute medical patients with normal vital signs at arrival, experience a deterioration in vital signs during the 24 first hours. This can potentially lead to dire consequences for these patients, as the risk of deterioration is present across all severity levels. The utilization of patient monitoring systems in the dispersed and shared working environments of EDs and acute wards may help to identify some of the reasons for failure to rescue patients. Thus, quantifying the extent to which a patient is being monitored, may be an aid to bridge the current gap between usage of automated and manual monitoring as clinical work will continue to depend on tacit knowledge and intuition. Several systems and protocols have been established to swiftly deal with identified deterioration. Most systems struggle with issues of clinical adherence and are difficult to assess on-the-fly, and in some cases nurses failed to notice abnormality in 43% of patients experiencing deterioration. Although the trajectories of patients' vital signs have been identified as more important than the initial scoring value, most of the widely used Track and Trigger systems lack a temporal aspect. Furthermore, a limited number of these Track and Trigger systems have been integrated into real time clinical decision support systems, which has not evolved much in the last decades. The PDWS deals with these challenges by aggregating and summarizing all vital values measured with the ED's patient monitors in the ongoing admission to intuitively present the state and trajectory. The investigators intend to determine if making the PDWS system available to nurses and physicians throughout the entire ED improves their ability to identify patients at risk of deterioration. To make this assessment, the PDWS will be evaluated in a cluster randomized trial (CRT) at two ED facilities in Denmark. The CRT is structured in three 5-week intervention, and three 5-week control periods, separated by a washout period of at least one week. The primary outcome is in-hospital deterioration - defined as transfer to the intensive care unit, heart/respiratory failure or death. The effect the PDWS will be assessed by comparing the proportions of events in each study arm using Pearsons's chi-squared test on these two samples. Furthermore, the technical and economical effects are evaluated using the Technology Acceptance Model, and the Model for Assessment of Telemedicine.
Early-onset pneumonia after out-of-hospital cardiac arrest is frequent. An association between early-onset pneumonia and an increase in morbidity has been reported in this population. The diagnosis of early-onset pneumonia inpatients with out-of-hospital cardiac arrest may be challenging as diagnosis criteria are unspecific in this setting. On the other hand some studies have reported an association between early antibiotics and better prognosis in patients with out-of-hospital cardiac arrest suggesting that early diagnosis and treatment of pneumonia would benefit to patients. Nonetheless, adminitration of antibiotics to any patients with out-of-hospital cardiac arrest would expose to antibiotic patients without infection and woould participate to increase in antibiotic resistance. Therefore, the PP-ACR study aims to evaluate the impact of a diagnosis algorithm including blinded sampling protected brushes on early-onset pneumonia treatment and patient prognosis after out-of-hospital cardiac arrest.
French guidelines for Cardio Pulmonary Resuscitation (CPR) consider Extra-Corporeal Life Support (ECLS) as one option in Refractory out-of hospital Cardiac Arrest (ROHCA) patients with a no-flow less than five minutes and absence of spontaneous circulation 30 minutes after initiation of advanced CPR. Duration of both pre-CPR arrest (no-flow) and of CPR (low-flow) have been systematically highlighted as crucial prognostic factors in all observational studies focused on ROHCA. In order to shorten the time to ECLS initiation, the most recent European Resuscitation Council guidelines recommend, in eligible ROHCA patients, a fast track access to ECLS implantation. CHRU Nancy elaborated an operational strategy which was designed to improve the enrolment of eligible ROHCA patients and to reduce the delay time between recognition and ECLS initiation. The objective of the present register was to assess prospectively the impact of this new operational strategy over a 5 years period.
The study is designed as a pilot, open-label study to investigate the feasibility and safety of selective cerebral hypothermia in OHCA patients receiving ECPR.
Incidence of non-hospital cardio-respiratory arrest (ACR) in France is around 40 000 cases per year, with mortality remaining very high, with 75% of patients dying before arrival in hospital. The investigators know some validated predictive factors for recovery of spontaneous cardiac activity (RACS) such as age, no flow (time between ACR and onset of CPR), type of initial electrical activity (FV, TVSP), or the value of CO2 expired. However, the use of these prognostic criteria in the conduct of CPR maneuvering is in practice limited. Lactate is now a well-known prognostic biological marker used in many pathological conditions such as shock states or the severe traumatized patient. Some data have also demonstrated the prognostic value of lactate on morbidity and mortality after ACR after resumption of spontaneous cardiac activity. The hypothesis of our study is that the evaluation of the initial lactate in the early cardiopulmonary resuscitation could be a prognostic factor of RACS.
Steroid use could be considered for patients with weaker adrenal function among those with post-cardiac arrest (CA) return of spontaneous circulation (ROSC), according to the former study. This finding is consistent with the medical background of this present study. This study will be the first to investigate these additional drugs of injection and associated prognosis in cardiac arrest (CA) patients outside the hospital, providing significant basic data.
Reliable data on stent thrombosis (ST) in comatose out of hospital cardiac arrest (OHCA) survivors is lacking. In comatose OHCA survivors suspicion of ST can be made with precise clinical monitoring of the patient with definite confirmation being possible only by coronary angiography or autopsy of deceased patients. However in addition to definite ST which can be confirmed using current protocols, additional ST which are clinically silent are plausible. These could be identified only by systematic coronary angiography of all OHCA survivors or by autopsy of deceased patients. Collectively with definite ST confirmed by coronary angiography upon clinical suspicion the incidence of all forms of ST in survivors of OHCA treated with PCI and hypothermia could be obtained. Consecutive comatose survivors of OHCA treated with percutaneous coronary intervention (PCI) and hypothermia will be included. All study participants will receive treatment per our established clinical protocol and will be followed for 10 days. In all patients in whom clinical suspicion of ST will be made immediate coronary angiography and if necessary PCI will be carried out. In all patients that will die in the observed period of 10 days autopsy will be performed. Survivors however will have an additional control coronary angiography on 10th day after admission, to assess presence of clinically silent ST. We expect that the incidence of true definitive ST in comatose OHCA survivors treated with urgent PCI with stenting and hypothermia is greater than one, which is confirmed on the basis of clinical suspicion by angiography or later with autopsy.
