Research is essential for the development of evidence-based emergency medical services (EMS) systems of care. When resources are scarce and gaps in evidence are large, a national agenda may inform the growth of EMS research in Canada. This mixed methods consensus study explores current barriers and existing strengths within Canadian EMS research, provides recommendations, and suggests EMS topics for future study.

Purposeful sampling was employed to invite EMS research stakeholders from various roles across the country. Study phases consisted of 1) baseline interviews of a subsample, 2) roundtable discussion, and 3) an online Delphi survey, in which participants scored each statement for importance. Consensus was defined a priori and met if 80% scored a statement as “important” or “very important.”

Fifty-three stakeholders participated, representing researchers (37.7%), EMS administrators (24.6%), clinicians/ providers (20.7%), and educators (17.0%). Participation rates were as follows: interviews, 13 of 13 (100%); roundtable, 47 of 53 (89%); survey round 1, 50 of 53 (94%); survey round 2, 47 of 53 (89%); and survey round 3, 40 of 53 (75%). A total of 141 statements were identified as important: 20 barriers, 54 strengths/opportunities, 31 recommendations, and 36 suggested topics for future research. Like statements were synthesized, resulting in barriers (n 5 10), strengths/opportunities (n 5 24), and recommendations (n 5 19), which were categorized as time, opportunities, and funding; education and mentorship; culture of research and collaboration; structure, process, and outcome of research; EMS and paramedic practice; and the future of the EMS Research Agenda.

Consensus-based key messages from this agenda should be considered when designing, funding, and publishing EMS research and will advance EMS research locally, regionally, and nationally.

This study forms the first phase in the development of the Canadian National EMS Research Agenda. The purpose was to understand the current state of emergency medical services (EMS) research through the barriers and opportunities perceived by key stakeholders in the Canadian system and to identify the recommendations this group had for moving forward.

This qualitative study was conducted in the spring of 2011 using one-on-one semistructured telephone interviews. Purposeful sampling was used to recruit a cross section of EMS research stakeholders, representing a breadth of geographic regions and roles. Data were collected until thematic saturation was reached. A constant comparative approach was used to develop a basic coding framework and identify emerging themes.

Twenty stakeholders were invited to participate, and saturation was reached after 13 interviews. Thematic saturation was used to ensure that the findings were grounded in the data. Four major themes were identified: 1) the need for additional research education within EMS; 2) the importance of creating an infrastructure to support pan-Canadian research collaboration; 3) addressing the complexities of involving EMS providers in research; and 4) considerations for a national research agenda.

This hypothesis-generating study reveals key areas regarding EMS research in Canada and through the guidance it provides is a first step in the development of a comprehensive national research agenda. Our intention is to collate the identified themes with the results of a larger roundtable discussion and Delphi survey and, in doing so, guide development of a Canadian national EMS research agenda.

Injection drug users (IDUs) often undergo procedural sedation and analgesia (PSA) in the emergency department (ED). We compared adverse events (AEs) for IDUs to those for non-IDUs receiving PSA for incision and drainage of cutaneous abscesses.

This was a retrospective analysis of a PSA safety audit. IDU status was prospectively documented among consecutive patients undergoing PSA at two urban EDs. Structured data describing comorbidities, vital signs, sedation regimens, and adverse events were collected. Primary outcome was the proportion of patients in each group experiencing an AE, whereas the secondary outcomes included recovery times.

Of 525 consecutive patients receiving PSA for incision and drainage of an abscess, 244 were deemed IDUs and 281 non-IDUs. IDUs received higher doses of sedatives and analgesics, and 14 experienced AEs (5.7%), whereas 10 non-IDUs had AEs (3.6%), for a risk difference of 2.1% (95% CI -1.8, 6.5). Median recovery times were 18 minutes (interquartile range [IQR] 10-36) for IDUs and 12 minutes (IQR 7-19) for non-IDUs, for a difference of 6 minutes (95% CI 2-9 minutes). Median sedation times were also longer in IDUs, for a difference of 6 minutes (95% CI 5-10 minutes). Of 20 IDU patients and 1 non-IDU patient admitted to hospital, none had experienced an AE related to PSA.

For ED patients requiring PSA for incision and drainage, IDUs had an AE rate similar to that of non-IDUs but longer sedation and recovery times. In experienced hands, PSA may be as safe in IDUs as in patients who do not use injection drugs.

The primary objective of this study was to quantify the impact of a clinical practice intervention to promote the delivery of salbutamol by metered-dose inhaler (MDI) in a pediatric emergency department (PED). A secondary objective was to retrospectively document the components of the intervention.

PED inventory data for salbutamol inhalation solution (nebules), MDIs, and holding chambers were obtained from the pharmacy department. Patient data were obtained fromthe hospital's decision support unit. Interrupted time series analysis was used to evaluate trends in salbutamol inventory data, patient triage acuity, and hospital admissions from January 1, 2003, to May 31, 2010. Interviews and administrative documents were used to identify components of the intervention, which began in 2006.

There was a 1,215% increase in the proportion of salbutamol delivered as MDIs compared to total inhaled salbutamol (MDI plus nebulization solution) following the intervention (95% CI 1,032% to 1,396%, p < 0.001). Increases in salbutamol MDI use were associated with the implementation of an institution-specific asthma care map. A relative decrease of 32% in the hospital admission rate (absolute –7.25%: 95% CI –8.31 to –6.19, p < 0.001) was associated with the change in salbutamol MDI use and the use of the asthma care map.

A multifaceted intervention, designed and implemented by local PED clinical leaders, resulted in a pronounced change in salbutamol inhalation practice, with an associated decrease in admission rates. This intervention demonstrated many of the criteria for successful health system change. Findings from this research may be contextualized to inform change elsewhere.
