Detailed Description
ED crowding limits the ability of the emergency providers to provide quality care, is a growing crisis in North America and Europe, and leads to unsafe and rushed disposition decisions which compromise patient care. On the other hand, hospital admission is expensive, and an increasing awareness of nosocomial morbidity and the harms of unnecessary testing and hospitalization exert countervailing pressure on low-yield admissions from the ED. Therefore, improved accuracy in ED disposition decision-making is more important than ever, and syncope typifies a common, high stakes condition in which improvements in efficiency are badly needed.
Identifying which patients will benefit from further cardiac rhythm monitoring and/or hospital admission is essential to reduce both adverse outcomes and high costs. A comprehensive literature review of risk-tools and international guidelines concede that previously published tools lack or have failed external validation, are excessively complex, include as outcomes obvious conditions readily identified during the index ED evaluation, or lacked power and specificity. These tools also do not offer specific clinical actions and are not supported by the guidelines. The CSRS addresses each of the above weaknesses and coupled with outpatient live cardiac monitoring is an innovative and standardized approach to ED syncope management to expedite ED care, improve patient safety and reduce healthcare costs. The investigators have identified the barriers and facilitators to effectively adapt knowledge into local contexts as per the Knowledge to Action cycle, and have selected implementation strategies accordingly. The proposed pilot study is a right step before widescale implementation.
The primary objective of this pilot study is to assess the feasibility of implementing the practice recommendations. The secondary objectives are to assess the effectiveness and safety of the intervention, implementation of the CSRS-based practice recommendations. Specific objectives include:
Feasibility objectives:
Primary: to assess the reach of the intervention Secondary: to assess the adoption, adherence, and sustainability of the intervention; to assess the acceptability, the feasibility of use and the complexity of the intervention; and to assess the satisfaction to the dose (i.e., exposure) of the intervention received including support and resources.
Effectiveness objectives:
Primary: to assess the impact on ED disposition time, defined as the time interval between ED physician initial assessment and ED disposition.
Secondary: to assess the impact on hospitalizations, investigations and consultations performed in the ED.
Safety objective: To assess mortality, return ED visits and hospitalization within 30-days and 1-year of the index ED visit (generic patient safety outcome) and to monitor the safety of the CSRS application by assessing the 30-day serious outcomes after ED disposition (syncope specific short-term serious outcome).
We will conduct the study over a 9-month period, with the TOH and QCH EDs receiving the intervention at the 3rd and 4th month respectively. The first month of the intervention period will be designated as a transition period during which we will undertake intense educational efforts. The total intervention period for the QCH and TOH EDs will be 5 and 6 months respectively.

Description
- Physician: physicians involved in ED syncope care
Patients:
- Inclusion Criteria: adult (aged > 18 years) patients who present within 24 hours of syncope
Exclusion Criteria:
- non-syncope (prolonged LOC >5 minutes, change in the mental status from baseline, patients with witnessed obvious seizure, or head trauma preceding the LOC),
- those unable to provide proper details - e.g., intoxication, and those with significant trauma requiring admission as per international consensus.
- patients who had a serious underlying condition identified during the index ED evaluation
- hospitalization for a reason other than syncope work-up (i.e. unable to cope at home).

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
Physicians using CSRS practice recommendation to treat syncope patients in ED.
During the control period, there will be no interventions.
The intervention is the knowledge translation of the CSRS practice recommendations.
The components of the practice recommendations include: 1) evidence-informed systematic clinical evaluation with appropriate history, physical examination and in-ED investigations (e.g.
troponin testing, work-up for pulmonary embolism and CT head) for detecting serious underlying conditions and predicting 30-day serious outcomes; 2) application of the CSRS for risk-stratification at the end of ED visit after no serious underlying conditions for the syncope were identified; 3) use of patient information materials to aid in disposition; 4) the use of 15-day outpatient cardiac monitoring for CSRS medium and high-risk patients upon ED discharge.
The ED physician or non-ED physician performing consultation on the patient can apply all the components of the practice recommendation and decide disposition of the patients who are eligible to be studied.
|
The intervention is knowledge translation of the CSRS practice recommendations; the application of the practice recommendations will occur during the patient's ED visit and patients who are eligible for 15-day cardiac rhythm monitoring will have Holter monitor applied at the time of ED discharge.
For the secondary objective to validate the accuracy of the ultra-low risk criteria of CSRS and assess for potential improvements in the practice recommendations and the prediction models we will request verbal consent during the index ED visit for addition of cardiac biomarker measurements [troponin and NT-proBNP] for patients who did not have such measurements performed as part of routine clinical care, and a 30-day telephone follow-up for serious outcome assessment.
Patients who do not consent will be excluded from these portions of the study but included in the health resource utilization and generic patient safety outcome assessment objectives.

Primary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Feasibility of implementing the practice recommendations.
Time Frame: The intervention period of 6 months
|
To assess the reach of the intervention.
We will adopt a pragmatic application of the RE-AIM (Reach Effectiveness Adoption Implementation Maintenance) framework to evaluate the pilot study outcomes.
The primary feasibility outcome is the Reach or penetration, the proportion of eligible patients who had the intervention applied.

ED disposition time
Time Frame: At time of ED disposition, an average timeframe is 6 hours
|
The ED disposition time more accurately reflects the active phase of ED physician care for collecting clinical information, work-up of patients and resolution of diagnostic uncertainty.
The longer interval of ED length of stay includes wait times both before and after, which are often determined by triage acuity as well as extraneous system factors (e.g.
ED and hospital crowding, staffing patterns, sudden influx of patients, availability of inpatient beds and overcapacity protocols, and availability of transportation for a subgroup patients for whom a decision to discharge has been made).
