Randomized Controlled Trial Multicenter StudyDesign of the PRINCESS trial: pre-hospital resuscitation intra-nasal cooling effectiveness survival study (PRINCESS).
Therapeutic hypothermia (TH, 32-34°C) has been shown to improve neurological outcome in comatose survivors of out-of-hospital cardiac arrest (OHCA) with ventricular tachycardia or fibrillation. Earlier initiation of TH may increase the beneficial effects. Experimental studies have suggested that starting TH during cardiopulmonary resuscitation (CPR) may further enhance its neuroprotective effects. The aim of this study was to evaluate whether intra-arrest TH (IATH), initiated in the field with trans nasal evaporative cooling (TNEC), would provide outcome benefits when compared to standard of care in patients being resuscitated from OHCA. ⋯ This ongoing trial will assess the impact of IATH with TNEC, which may be able to rapidly induce brain cooling and have fewer side effects than other methods, such as cold fluid infusion. If this intervention is found to improve neurological outcome, its early use in the pre-hospital setting will be considered as an early neuro-protective strategy in OHCA.

The accuracy of surrogate decision makers: informed consent in hypothetical acute stroke scenarios.
Over one third of stroke patients have cognitive or language deficits such that they require surrogate consent for acute stroke treatment or enrollment into acute stroke trials. Little is known about the agreement of stroke patients and surrogates in this time-sensitive decision-making process. We sought to determine patient and surrogate agreement in 4 hypothetical acute stroke scenarios. ⋯ Surrogates accurately predict patient preferences for standard acute stroke treatments. However, the accuracy decreases when predicting research participation suggesting that the degree of surrogate agreement is dependent on the type of decision being made. Further research is needed to more thoroughly characterize surrogate decision-making in acute stroke situations.

Multicenter StudyMethodology for developing quality indicators for the care of older people in the Emergency Department.
Compared with younger people, older people have a higher risk of adverse health outcomes when presenting to emergency departments. As the population ages, older people will make up an increasing proportion of the emergency department population. Therefore it is timely that consideration be given to the quality of care received by older persons in emergency departments, and to consideration of those older people with special needs. Particular attention will be focused on important groups of older people, such as patients with cognitive impairment, residents of long term care and patients with palliative care needs. This project will develop a suite of quality indicators focused on the care of older persons in the emergency department. ⋯ The predicted burgeoning in the number of older persons presenting to emergency departments combined with the recognised quality deficiencies in emergency department care delivery to this population, highlight the need for a quality framework for the care of older persons in emergency departments. Additionally, high quality of care is associated with improved survival & health outcomes of elderly patients. The development of well-selected, validated and economical quality indicators will allow appropriate targeting of resources (financial, education or quality management) to improve quality in areas with maximum potential for improvement.

Randomized Controlled TrialImplementing wait-time reductions under Ontario government benchmarks (Pay-for-Results): a Cluster Randomized Trial of the Effect of a Physician-Nurse Supplementary Triage Assistance team (MDRNSTAT) on emergency department patient wait times.
Internationally, emergency departments are struggling with crowding and its associated morbidity, mortality, and decreased patient and health-care worker satisfaction. The objective was to evaluate the addition of a MDRNSTAT (Physician (MD)-Nurse (RN) Supplementary Team At Triage) on emergency department patient flow and quality of care. ⋯ The intervention reduced delays and left-without-being-seen rate without increased return visits or jeopardizing urgent care of severely ill patients.

Randomized Controlled TrialImpact of a stress coping strategy on perceived stress levels and performance during a simulated cardiopulmonary resuscitation: a randomized controlled trial.
Cardiopulmonary resuscitation (CPR) causes significant stress for the rescuers which may cause deficiencies in attention and increase distractibility. This may lead to misjudgements of priorities and delays in CPR performance, which may further increase mental stress (vicious cycle). This study assessed the impact of a task-focusing strategy on perceived stress levels and performance during a simulated CPR scenario. ⋯ A brief stress-coping strategy moderately decreased perceived stress without significantly affecting performance in a simulated CPR. Further studies should investigate more intense interventions for reducing stress.
