Objectives:
To establish consensus on the most important clinical decisions paramedics make during high-acuity emergency calls and to visualize these decisions on a process map of an emergency call. A secondary objective was to measure agreement among paramedics and medical director panel members.
Methods:
A multiround online survey of Canadian paramedics and medical directors. In round 1, participants listed important clinical decisions. In round 2, participants scored each decision in terms of its importance for patient outcome and safety. In rounds 3 and 4, participants could revise their scores. Consensus was defined a priori: 80% or more agreement that a decision was important or extremely important. The included decisions were plotted on a process map of a typical emergency call.
Results:
The panel response rates were as follows: round 1, 96%; round 2, 92%; round 3, 83%; and round 4, 96%. Consensus was reached on 42 decisions, grouped into six categories: airway management (n = 13); assessment (n = 3); cardiac management (n = 7); drug administration (n = 9); scene management (n = 4); and general treatment (n = 6). The on-scene treatment phase of the process map was found to have the highest decision density. Paramedics and medical directors differed in their scoring in 5 of 42 decisions (p < 0.05 or less).
Conclusion:
Consensus was reached among paramedics and medical directors on 42 decisions important for clinical outcome and patient safety. These decisions were visualized on a process map of an emergency call to learn more about where decision density exists during a typical call.

Objective: Timely reperfusion therapy for ST-elevation myocardial infarction (STEMI) is an important determinant of outcome, yet targets for time to treatment are frequently unmet in North America. Prehospital strategies can reduce time to reperfusion. We sought to determine the extent to which emergency medical services (EMS) use these strategies in Canada.
Methods: We carried out a cross-sectional survey in 2007 of ground EMS operators in British Columbia, Alberta, Ontario, Quebec and Nova Scotia. We focused on the use of 4 prehospital strategies: 1) 12-lead electrocardiogram (ECG), 2) routine expedited emergency department (ED) transfer of STEMI patients (from a referring ED to a percutaneous coronary intervention [PCI] centre), 3) prehospital bypass (ambulance bypass of local EDs to transport patients directly to PCI centres) and 4) prehospital fibrinolysis.
Results: Ninety-seven ambulance operators were surveyed, representing 15 681 paramedics serving 97% of the combined provincial populations. Of the operators surveyed, 68% (95% confidence interval [CI] 59%-77%) had ambulances equipped with 12-lead ECGs, ranging from 40% in Quebec to 100% in Alberta and Nova Scotia. Overall, 47% (95% CI 46%-48%) of paramedics were trained in ECG acquisition and 40% (95% CI 39%-41%) were trained in ECG interpretation. Only 18% (95% CI 10%-25%) of operators had prehospital bypass protocols; 45% (95% CI 35%-55%) had protocols for expedited ED transfer. Prehospital fibrinolysis was available only in Alberta. All EMS operators in British Columbia, Alberta and Nova Scotia used at least 1 of the 4 prehospital strategies, and one-third of operators in Ontario and Quebec used 0 of 4. In major urban centres, at least 1 of the 3 prehospital strategies 12-lead ECG acquisition, bypass or expedited transfer was used, but there was considerable variation within and across provinces.
Conclusion: The implementation of widely recommended prehospital STEMI strategies varies substantially across the 5 provinces studied, and relatively simple existing technologies, such as prehospital ECGs, are underused in many regions. Substantial improvements in prehospital services and better integration with hospital-based care will be necessary in many regions of Canada if optimal times to reperfusion, and associated outcomes, are to be achieved. -

Objective: We sought to assess the knowledge of, use of and barriers to the use of personal protective equipment for airway management among emergency medical technicians (EMTs) during and since the 2003 Canadian outbreak of Severe Acute Respiratory Syndrome (SARS).
Methods: Using a cross-sectional survey, EMTs in Toronto, Ont., were surveyed 1 year after the SARS outbreak during mandatory training on the use of personal protective equipment in airway management during the outbreak and just before taking the survey. Practices that were addressed reflected government directives on the use of this equipment. Main outcome measures included the frequency of personal protective equipment use and, as applicable, why particular items were not always used.
Results: The response rate was 67.3% (n = 230). During the SARS outbreak, an N95-type particulate respirator was reported to be always used by 91.5% of respondents. Conversely, 72.9% of the respondents reported that they never used the open face hood. Equipment availability and vision impairment were often cited as impediments to personal protective equipment use. In nonoutbreak conditions, only the antimicrobial airway filter was most often reported to be always used (52.0%), while other items were used at an intermediate frequency. The most common reason for not always donning equipment was that paramedics deemed it unnecessary for the situation.
Conclusion: Personal protective equipment is not consistently employed as per medical directives. Reasons given for nonuse included nonavailability, judgment of nonnecessity or technical difficulties. There are important public health implications of noncompliance.

Introduction: Do not resuscitate (DNR) orders are commonly accepted in most health care settings, but are less widely recognized in the prehospital setting. We describe the implementation of and satisfaction with a prehospital DNR protocol that allows paramedics to honour verbal and non-standard written DNR requests.
Methods: This prospective observational study reviewed all cardiac arrests in southeastern Ontario between March 1, 2003 and September 31, 2005. Following a verbal or non-standard written DNR request, paramedics completed a questionnaire and a follow-up structured telephone interview was conducted with surrogate decision makers (SDMs).
Results: There were 1890 cardiac arrests during the study period, of which 86 met our inclusion criteria. Paramedic surveys were available for 82 cases (95%), and surrogate decision makers (SDMs) were successfully contacted in 50 (58%) of them. Two SDMs declined to be interviewed. The mean patient age was 72.7 (standard deviation 13.8) years and 65% were male. Sixty-three (73%) of DNR requests were verbal, and 23 (27%) were written. The mean paramedic comfort was rated 4.9 on a 5-point Likert scale (with 5 being "very comfortable") (95% confidence interval [CI] 4.9-5.0). The mean SDM comfort was rated by paramedics as 4.9 (95% CI 4.8-4.9). SDMs reported comfort in withholding CPR in 47 of 48 cases (98%), and with paramedic care in all cases. One SDM stated that although it was consistent with the patient's wishes, she was uncomfortable having to make the DNR request.
Conclusions: Satisfaction with this novel prehospital DNR protocol was uniformly high among paramedic and SDM respondents. It appears that such a protocol is feasible and acceptable for the prehospital setting. Our conclusions are limited by a small sample size, the lack of a comparison group, and limited follow-up.

Objective: To determine the inter-observer agreement on triage assignment by first-time users with diverse training and background using the Canadian Emergency Department Triage and Acuity Scale (CTAS).
Methods: Twenty emergency care providers (5 physicians, 5 nurses, 5 Basic Life Support paramedics and 5 Advanced Life Support paramedics) at a large urban teaching hospital participated in the study. Observers used the 5-level CTAS to independently assign triage levels for 42 case scenarios abstracted from actual emergency department patient presentations. Case scenarios consisted of vital signs, mode of arrival, presenting complaint and verbatim triage nursing notes. Participants were not given any specific training on the scale, although a detailed one-page summary was included with each questionnaire. Kappa values with quadratic weights were used to measure agreement for the study group as a whole and for each profession.
Results: For the 41 case scenarios analyzed, the overall agreement was significant (quadratic-weighted K = 0.77, 95% confidence interval, 0.76-0.78). For all observers, modal agreement within one triage level was 94.9%. Exact modal agreement was 63.4%. Agreement varied by triage level and was highest for Level I (most urgent). A reasonably high level of intra- and inter-professional agreement was also seen.
Conclusions: Despite minimal experience with the CTAS, inter-observer agreement among emergency care providers with different backgrounds was significant.
