Stroke is a major emergency that can cause a significant morbidity and mortality. Advancement in stroke management in recent years has allowed more patients to be diagnosed and treated by stroke teams; however, stroke is a time-sensitive emergency that requires a high level of coordination, particularly within the prehospital phase. This research is to determine whether patients received by Emergency Medical Services (EMS) at a tertiary health care facility had shorter stroke team activation, time to computed tomography (CT), or time to receive intravenous thrombolytics.

This research is a prospective cohort study of adults with stroke symptoms who required stroke team activation at a tertiary medical facility. The study included all patients received from September 1, 2017 through August 31, 2018. The primary outcome was the time difference to stroke team activation between patients received by EMS compared to patients that arrived by a private method of transportation. The secondary outcomes were the difference in time to CT scan and the time to receive intravenous recombinant tissue plasminogen activator (rtPA).

There were 75 (34.1%) patients who had been received by EMS, while 145 (65.9%) patients arrived via private transportation method (private car or by a friend/family member). The mean time to stroke team activation, time to CT, and time to receive thrombolytic therapy for the EMS group were: 8.19 (95% CI, 6.97 - 9.41) minutes; 18 (95% CI, 15.9 - 20.1) minutes; and 13.1 (95% CI, 6.95 - 19.3) minutes, respectively. Those for the private car group, on the other hand, were: 16 (95% CI, 12.4 - 19.6) minutes; 23.39 (95% CI, 19.6 - 27.2) minutes; and nine (95% CI, 4.54 -13.5) minutes, respectively. There was a significantly shorter time to stroke team activation for patients arriving via EMS compared to private car (P ≤ .00), but no significant difference was found on time to CT (P = .259) or time to receive rtPA (P = .100).

Emergency Medical Service transportation of stroke patients can significantly shorten the time to stroke team activation, leading to shorter triage and accelerated patient management. However, there was no statistical difference in time to CT or time to receive rtPA. Patients with stroke symptoms may benefit more from EMS transportation compared to private methods of transportation.

According to Ontario, Canada’s Basic Life Support Patient Care Standards, Emergency Medical Services (EMS) on-scene time (OST) for trauma calls should not exceed 10 minutes, unless there are extenuating circumstances. The time to definitive care can have a significant impact on the morbidity and mortality of trauma patients. This is the first Canadian study to investigate why this is the case by giving a voice to those most involved in prehospital care: the paramedics themselves. It is also the first study to explore this issue from a complex, adaptive systems approach which recognizes that OSTs may be impacted by local, contextual features.

Research addressed the following problem: what are the facilitators and barriers to achieving 10-minute OSTs?

This project used a descriptive, qualitative design to examine facilitators and barriers to achieving 10-minute OSTs on trauma calls, from the perspective of paramedics. Paramedics from a regional Emergency Services organization were interviewed extensively over the course of one year, using qualitative interviewing techniques developed by experts in that field. All interviews were recorded, transcribed, and entered into NVivo for Mac (QSR International; Victoria, Australia) software that supports qualitative research, for ease of data analysis. Researcher triangulation was used to ensure credibility of the data.

Thirteen percent of the calls had OSTs that were less than 10 minutes. The following six categories were outlined by the paramedics as impacting the duration of OSTs: (1) scene characteristics; (2) the presence and effectiveness of allied services; (3) communication with dispatch; (4) the paramedics’ ability to effectively manage the scene; (5) current policies; and (6) the quantity and design of equipment.

These findings demonstrate the complexity of the prehospital environment and bring into question the feasibility of the 10-minute OST standard.LevitanM, LawMP, FerronR, Lutz-GraulK.

Nurses and respiratory therapists are seldom allowed to use automated external defibrillators (AED) during in-hospital cardiac arrest. This can result in significant time delays before defibrillation occurs and lower survival for cardiac arrest victims. We sought to identify barriers and facilitators to AED use by nurses and respiratory therapists.

We conducted semi-structured qualitative interviews with a purposeful sample of nurses and respiratory therapists. We developed the interview guide based on the constructs of the theory of planned behaviour, which elicits salient attitudes, social influences, and control beliefs potentially influencing the intent to use an AED. Interviews were recorded, transcribed verbatim, and analysed until achieving data saturation. Two independent reviewers performed inductive analyses to identify emerging categories and themes, and ranked them by frequency of the number of participants stating the topic.

Demographics for the 24 interviewees include mean age 40.5, 79.2% female, 87.5% performed cardiopulmonary resuscitation (CPR), 29.2% defibrillated a patient. Identified attitudes pertained to the timeliness of defibrillation, patient survival, simplicity of AED use, accuracy of rhythm recognition, and harm to self or others. Social influences consisted of physician and hospital administration support of AED use. Control beliefs included training on AED use, policy allowing AED use, familiarity with AED, and task burden during resuscitation.

Most nurses and respiratory therapists intended to use an AED if permitted to do so by a medical directive. Successful implementation would require educational initiatives focusing on safety and efficacy of AEDs, support from physicians and hospital administrators, and additional training on AED use.

Disasters are high-stakes, low-frequency events. Telemedicine may offer a useful adjunct for paramedics performing disaster triage. The objective of this study was to determine the feasibility of telemedicine in disaster triage, and to determine whether telemedicine has an effect on the accuracy of triage or the time needed to perform triage.

This is a feasibility study in which an intervention team of two paramedics used the mobile device Google Glass (Google Inc; Mountain View, California USA) to communicate with an off-site physician disaster expert. The paramedic team triaged simulated disaster victims at the triennial drill of a commercial airport. The simulated victims had preassigned expected triage levels. The physician had an audio-video interface with the paramedic team and was able to observe the victims remotely. A control team of two paramedics performed disaster triage in the usual fashion. Both teams used the SMART Triage System (TSG Associates LLP; Halifax, England), which assigns patients into Red, Yellow, Green, and Black triage categories. The paramedics were video recorded, and their time required to triage was logged. It was determined whether the intervention team and the control team varied regarding accuracy of triage. Finally, the amount of time the intervention team needed to triage patients when telemedicine was used was compared to when that team did not use telemedicine.

The two teams triaged the same 20 patients. There was no significant difference between the two groups in overall triage accuracy (85.7% for the intervention group vs 75.9% for the control group; P = .39). Two patients were triaged with telemedicine. For the intervention group, there was a significant difference in time to triage patients with telemedicine versus those without telemedicine (35.5 seconds; 95% CI, 72.5-143.5 vs 18.5 seconds; 95% CI, 13.4-23.6; P = .041).

There was no increase in triage accuracy when paramedics evaluating disaster victims used telemedicine, and telemedicine required more time than conventional triage. There are a number of obstacles to available technology that, if overcome, might improve the utility of telemedicine in disaster response.

Behavioral and social science research suggests that job satisfaction and job performance are positively correlated. It is important that Emergency Medical Services managers identify predictors of job satisfaction in order to maximize job performance among prehospital personnel.

Identify job stressors that predict the level of job satisfaction among prehospital personnel.

The study was conducted with in a large, urban Emergency Medical Services (Emergency Medical Services) service performing approximately 60,000 Advanced Life Support (Advanced Life Support) responses annually. Using focus groups and informal interviews, potential predictors of global job satisfaction were identified. These factors included: interactions with hospital nurses and physicians; on-line communications; dispatching; training provided by the ambulance service; relationship with supervisors and; standing orders as presently employed by the ambulance service. These factors were incorporated into a 21 item questionnaire including one item measuring global job satisfaction, 14 items measuring potential predictors of satisfaction, and seven questions exploring demographic information such as age, gender, race, years of experience, and years with the company. The survey was administered to all paramedics and Emergency Medical Technicians (Emergency Medical Technicians s) Results of the survey were analyzed using univariate and multivariate techniques to identify predictors of global job satisfaction.

Ninety paramedics and Emergency Medical Technicians participated in the study, a response rate of 57.3%. Job satisfaction was cited as extremely satisfying by 11%, very satisfying by 29%, satisfying by 45%, and not satisfying by 15% of respondents. On univariate analysis, only the quality of training, quality of physician interaction, and career choice were associated with global job satisfaction. On multivariate analysis, only career choice (p = 0.005) and quality of physician interaction (p = 0.05) were predictive of global job satisfaction

Quality of career choice and interactions with physicians are predictive of global job satisfaction within this urban emergency medical service (Emergency Medical Technicians). Future studies should examine specific characteristics of the physician-paramedic interface that influence job satisfaction and attempt to generalize these results to other settings.

Almost all North American cities have first responder programs. To date there is no published documentation of the roles first responders play, nor of the frequency and type of interventions they perform. Many urban stakeholders question the utility and safety of routinely dispatching large vehicles emergently to calls that may not require their services. Real world data on first responder interventions will help emergency medical services (EMS) directors and planners determine manpower requirements, assess training needs, and optimize dispatch protocols to reduce the rate of inappropriate “code 3” (lights and siren) responses.

Our objectives were to determine how often first responders arrive first on scene, to estimate the time interval between first response and EMS response, and to examine the frequency and type of interventions performed by first responders.

In a prospective observational study, trained observers were assigned to fire department first responder (FDFR) units. These observers recorded on-scene times for FDFR and EMS units, and documented the performance of first responder interventions.

FDFRs arrived first on scene in 49% of code 3 calls. They performed critical interventions in 18% of calls attended and 36% of calls where they arrived first. Oxygen administration was the most frequent critical intervention, yet occult hypoxemia was common and compliance with oxygen administration protocols was poor.

First responders perform critical interventions during a minority of code 3 calls, even when “critical” is defined generously. Many “lights and siren” dispatches are unnecessary. Future research should attempt to identify dispatch criteria that more accurately predict the need for first responder intervention. First responder training and continuous quality improvement (CQI) should focus on interventions that are performed with some regularity, particularly oxygen administration.
