Public awareness and knowledge of sepsis: a cross-sectional survey of adults in Canada.

BACKGROUND: Sepsis is a life-threatening complication of the body's response to infection. The financial, medical, and psychological costs of sepsis to individuals and to the healthcare system are high. Most sepsis cases originate in the community, making public awareness of sepsis essential to early diagnosis and treatment. There has been no comprehensive examination of adult's sepsis knowledge in Canada. METHODS: We administered an online structured survey to English- or French-literate adults in Canada. The questionnaire comprised 28 questions in three domains: awareness, knowledge, and information access. Sampling was stratified by age, sex, and geography and weighted to 2016 census data. We used descriptive statistics to summarize responses; demographic differences were tested using the Rao-Scott correction for weighted chi-squared tests and associations using multiple variable regression. RESULTS: Sixty-one percent of 3200 adults sampled had heard of sepsis. Awareness differed by respondent's residential region, sex, education, and ethnic group (p < 0.001, all). The odds of having heard of sepsis were higher for females, older adults, respondents with some or completed college/university education, and respondents who self-identified as Black, White, or of mixed ethnicity (p < 0.01, all). Respondent's knowledge of sepsis definitions, symptoms, risk factors, and prevention measures was generally low (53.0%, 31.5%, 16.5%, and 36.3%, respectively). Only 25% of respondents recognized vaccination as a preventive strategy. The strongest predictors of sepsis knowledge were previous exposure to sepsis, healthcare employment, female sex, and a college/university education (p < 0.001, all). Respondents most frequently reported hearing about sepsis through television (27.7%) and preferred to learn about sepsis from healthcare providers (53.1%). CONCLUSIONS: Sepsis can quickly cause life-altering physical and psychological effects and 39% of adults sampled in Canada have not heard of it. Critically, a minority (32%) knew about signs, risk factors, and strategies to lower risk. Education initiatives should focus messaging on infection prevention, employ broad media strategies, and use primary healthcare providers to disseminate evidence-based information. Future work could explore whether efforts to raise public awareness of sepsis might be bolstered or hindered by current discourse around COVID-19, particularly those centered on vaccination.

Paramedic Clinical Consults with a Paramedic or Nurse in an EMS Communications Center Compared to Traditional Online Physician Consults.

OBJECTIVES: In many emergency medical services (EMS) systems, a direct medical oversight physician is available to paramedics for mandatory and/or elective consultations. At the time of this study, a clinical support desk (CSD) was being implemented within the medical communications center of a provincial EMS system in addition to the physician resource. The CSD was initially staffed with a registered nurse or an advanced care paramedic. The objective of the current study was to compare CSD "peer to peer" consults versus physician consults with regards to consultation patterns, transport dispositions, and patient safety measures. METHODS: This retrospective cohort study analyzed 2 months before (September 1 to October 31, 2012) and 2 months after (September 1 to October 31, 2013) implementation of the CSD. In the before period, all clinical consults were fielded by the direct medical oversight physician. In the after period, consults were fielded by the physician, CSD or both. EMS databases were queried, and manual chart review and abstraction of audio recordings were done. Relapses back to EMS within 48 hours of non-transport were measured. RESULTS: 1621 consults were included, with 764 consults in the before period and 857 after (p = 0.02). The number of physician consults decreased from 764 before to 464 after (39.2%, p < 0.001), with the CSD taking 325 (37.9%) consults. The CSD was consulted more for police custody and trip destination. The physician was consulted more for cease resuscitation and clinical consults prior to medication administration. Overall non-transport rates were 595/764 before (77.9%), and 646/857 after (75.4%) (p = 0.2). Non-transports were 233/325 (71.7%) via the CSD, 364/464 (78.4%) via the physician, and 49/68 (72.1%) when both were involved (p = 0.07). Rate of relapse to EMS was similar before (25/524, 4.8%) and after (26/568, 4.6%) (p = 0.76), and between CSD (12/216, 5.5%) and physician consults (13/325, 4.0%) in the after period (p = 0.41). CONCLUSION: The introduction of a novel "peer-to-peer" consult program was associated with an increased total number of consults made and reduced call volume for direct medical oversight physicians. There was no change in the patient safety measure studied.

The Prevalence and Characteristics of Non-Transports in a Provincial Emergency Medical Services System: A Population-Based Study.

BACKGROUND: Emergency Medical Services (EMS) provide patients with out-of-hospital care, but not all patients are transported to the hospital. Non-transport represents an often undefined yet potentially significant risk for poor clinical outcomes. Few North American studies have quantified this risk. OBJECTIVE: The objectives of this study were to determine the prevalence of non-transport and 48-h adverse event (composite of relapse responses that resulted in transport or death) and to identify characteristics associated with either outcome. METHODS: An analysis of pooled cross-sectional, population-based administrative data from the provincial EMS electronic charting system in 2014 was conducted. Determination of non-transport was based on recorded call outcome. The data were searched by patient identifiers to determine the 48-h adverse event rate. Paramedic-documented patient, operational, and environmental characteristics were included in the logistic regression models. RESULTS: Of 74,293 emergency responses, 14,072 (18.9%) were non-transport and, of those, 798 (5.6%) resulted in a 48-h adverse event. The characteristics statistically significantly and independently associated with non-transport and 48-h adverse event were younger age (odds ratio [OR] 1.72; 99.9% confidence interval [CI] 1.46-2.02), nonspecific paramedic clinical impression (OR 5; 99.9% CI 4.48-5.57), more than 7 comorbidities (OR 0.47; 99.9% CI 0.42-0.53), and incident location (jail) (OR 2.88; 99.9% CI 2.22-3.74). CONCLUSIONS: This study provides an estimate of prevalence of non-transports and 48-h adverse event in a provincial mixed rural-urban EMS system. The results of this study describe the scope of non-transport and present several characteristics associated with non-transport. Future study should examine the appropriateness of EMS responses and methods to mitigate risk of adverse event after non-transport.

A review on ambulance offload delay literature.

Ambulance offload delay (AOD) occurs when care of incoming ambulance patients cannot be transferred immediately from paramedics to staff in a hospital emergency department (ED). This is typically due to emergency department congestion. This problem has become a significant concern for many health care providers and has attracted the attention of many researchers and practitioners. This article reviews literature which addresses the ambulance offload delay problem. The review is organized by the following topics: improved understanding and assessment of the problem, analysis of the root causes and impacts of the problem, and development and evaluation of interventions. The review found that many researchers have investigated areas of emergency department crowding and ambulance diversion; however, research focused solely on the ambulance offload delay problem is limited. Of the 137 articles reviewed, 28 articles were identified which studied the causes of ambulance offload delay, 14 articles studied its effects, and 89 articles studied proposed solutions (of which, 58 articles studied ambulance diversion and 31 articles studied other interventions). A common theme found throughout the reviewed articles was that this problem includes clinical, operational, and administrative perspectives, and therefore must be addressed in a system-wide manner to be mitigated. The most common intervention type was ambulance diversion. Yet, it yields controversial results. A number of recommendations are made with respect to future research in this area. These include conducting system-wide mitigation intervention, addressing root causes of ED crowding and access block, and providing more operations research models to evaluate AOD mitigation interventions prior implementations. In addition, measurements of AOD should be improved to assess the size and magnitude of this problem more accurately.

Impact of a Novel Collaborative Long-Term Care -EMS Model: A Before-and-After Cohort Analysis of an Extended Care Paramedic Program.

To compare system and clinical outcomes before and after an extended care paramedic (ECP) program was implemented to better address the emergency needs of long-term care (LTC) residents. Data were collected from emergency medical services (EMS), hospital, and ten LTC facility charts for two five-month time periods, before and after ECP implementation. Outcomes include: number of EMS patients transported to emergency department (ED) and several clinical, safety, and system secondary outcomes. Statistics included descriptive, chi-squared, t-tests, and ANOVA; α = <0.05. 413 cases were included (before: n = 136, 33%; after n = 277, 67%). Median patient age was 85 years (IQR 77-91 years) and 292/413 (70.7%) were female. The number of transports to ED before implementation was 129/136 (94.9%), with 147/224 (65.6%) after, p < 0.001. In the after period, fewer patients seen by ECP were transported: 58/128 (45.3%) vs. 89/96 (92.7%) of those not seen by ECP, p < 0.001. Hospital admissions were similar between phases: 39/120 (32.5%) vs. 56/213 (29.4%), p = NS, but in the after phase, fewer ECP patients were admitted vs. non-ECP: 21/125 (16.8%) vs. 35/88 (39.8%), p < 0.001. Mean EMS call time (dispatch to arrive ED or clear scene) was shorter before than after: 25 minutes vs. 57 minutes, p < 0.001. In the after period, calls with ECP were longer than without ECP: 1 hour, 35 minutes vs. 30 minutes, p < 0.001. The mean patient ED length-of-stay was similar before and after: 7 hours, 29 minutes compared to 8 hours, 11 minutes; p = NS. In the after phase, ED length-of-stay was somewhat shorter with ECPs vs. no ECPs: 7 hours, 5 minutes vs. 9 hours, p = NS. There were zero relapses after no-transport in the before phase and three relapses from 77 calls not transported in the after phase (3/77, 3.9%); two involved ECP (2/70, 2.8%). Reductions were observed in the number of LTC patients transported to the ED when the ECP program was introduced, with fewer patients admitted to the hospital. EMS calls take longer with ECP involved. The addition of ECP to the LTC model of care appears to be beneficial and safe, with few relapse calls identified.

Insights into the implementation and operation of a novel paramedic long-term care program.

OBJECTIVE: An extended-care paramedic (ECP) program was implemented to provide emergency assessment and care on site to long-term care (LTC) residents suffering acute illness or injury. A single paramedic works collaboratively with physicians, LTC staff, patient, and family to develop care plans to address acute situations, often avoiding the need to transport the resident to hospital. We sought to identify insights gained and lessons learned during implementation and operation of this novel program. METHODS: The perceptions and experiences of various stakeholders were explored in focus groups, using a semi-structured interview guide. Two investigators independently conducted thematic analysis and identified emerging themes and related codes. Congruence and differences were discussed to achieve consensus. RESULTS: Twenty-one participants took part in four homogeneous focus groups: paramedics and dispatchers, ECPs, ECP oversight physicians, and decision-makers. The key themes identified were (1) program implementation, (2) ECP process of care, (3) communications, and (4) end-of-life care. CONCLUSION: The ECP program has positive implications for the relationship between EMS and LTC, requires additional paramedic training, and can positively affect LTC patient experiences during acute medical events. ECPs have a novel role to play in end-of-life care and find this new role rewarding.

Can emergency medical services use turnaround time as a proxy for measuring ambulance offload time?

BACKGROUND: "Offload delay" occurs when the transfer of care from paramedics to the emergency department (ED) is prolonged. Accurately measuring the delivery interval or "offload" is important, because it represents the time patients are waiting for definitive care. Because recording this interval presents a significant challenge, most emergency medical services systems only measure the complete at-hospital time or "turnaround interval," and most offload delay research and policy is based on this proxy. OBJECTIVE: This study sought to test the validity of using the turnaround interval as a surrogate for the delivery interval. METHODS: This observational study examined levels of correspondence, or correlation, between delivery interval and turnaround interval, to assess whether turnaround is a reasonable surrogate for delivery. Delivery and turnaround intervals were logged by Richmond Ambulance Authority (RAA) in Richmond, Virginia, United States from April 1 to December 31, 2008. A total of 1732 ambulance runs from RAA were included. RESULTS: Pearson's correlation analysis showed a good correlation between turnaround and actual offload time (delivery), with a coefficient (r) of 0.753. A post hoc analysis explored patterns in the relationship, which is quite complex. CONCLUSION: The results show that the correlation between the delivery and turnaround intervals is good. However, there remains much to be learned about the at-hospital time intervals and how to use these data to make decisions that will improve resource utilization and patient care. Efforts to establish a method to accurately record the delivery interval and to understand the at-hospital portion of the ambulance response are necessary.

Paramedics Providing Palliative Care at Home: A Retrospective Cohort Study Comparing Symptom Management of Breathlessness and Pain in Cancer Versus Non-Cancer Conditions.

Background Palliative care aims to alleviate pain and distressing symptoms, affirm life, and offer support to patients and their caregivers. For many, the expressed preference is to die at home. As a result, there is growing recognition that paramedics can play an integral role at the end of life for symptom relief. Paramedic comfort with symptom management in the palliative care context is suspected, based on past work, to be higher for cancer as opposed to non-cancer life advanced disease. The objective of this study was to explore the paramedic management of patients with cancer and non-cancer advanced disease, using pain and breathlessness as key symptoms. Methods  A retrospective cohort study was conducted. Paramedic electronic patient care records were queried for calls with palliative goals of care between July 1, 2015, and June 30, 2016, in Nova Scotia, Canada, which was the first year of the Paramedics Providing Palliative Care program. A manual chart review of a subgroup of 100 consecutive charts was completed to gain deeper insight. A descriptive analysis was conducted to understand practice variation within this population.  Results The electronic query returned 1909 calls with a palliative approach. A total of 765 (40.1%) had cancer. The most common non-cancer disease category was respiratory. The top chief complaint was respiratory distress in both cancer and non-cancer populations. Medication was administered more often for pain (80%) compared to breathlessness (46.5%). Paramedics were more likely to call Medical Oversight Physicians for pain control advice. Post-treatment pain scores were documented infrequently. In the chart review, symptom management using the patient's own medications occurred in 17% of cases while an additional 5% of cases involved a combination of the patient's medications and paramedic service formulary. Conclusion  The non-cancer population was less likely to have a non-transport outcome. Opportunities for improvement of symptom management were noted for pain and particularly so for breathlessness. Increased comfort with a palliative approach in the non-cancer disease cohort as well as with this key symptom will be a key to the success of the program.

Chest compression fraction in simulated cardiac arrest management by primary care paramedics: King laryngeal tube airway versus basic airway management.

OBJECTIVE: The objective of this randomized simulation study was to determine whether use of the King laryngeal tube (KLT) airway resulted in differences in chest compression fraction (CCF) during simulated cardiac arrest managed by primary care paramedics (PCPs), as compared with basic airway management (bag-mask ventilation [BMV]). METHODS: The KLT was introduced to all providers in our system at the time of study initiation. All participants received the same training, and were not aware that the primary outcome of the study was CCF. Standard airway management by PCPs prior to this was BMV. Pairs of PCPs were randomized to use KLT or BMV during a scripted 6-minute cardiac arrest scenario. The scenarios were videotaped, and data were abstracted by a single investigator. The CCF was calculated (fraction of time chest compressions were done/total scenario time). The CCF, number of seconds to first ventilation, and number of seconds to first compression were compared using the Mann-Whitney U test. RESULTS: Sixty-seven pairs of PCPs participated: 30 in the KLT arm and 37 in the BMV arm. Demographics were similar in each group: KLT 68.3% males, BMV 55.4% males; KLT mean age 33.52 years (standard deviation [SD]: 11.95), BMV mean age 32.07 years (SD: 8.78); and KLT mean years of experience 9.03 (SD: 9.86), BMV mean years of experience 6.59 (SD: 6.58). The CCF was higher in the KLT group: median 0.82 (interquartile range [IQR] 0.71-0.88) compared with the BMV group: median 0.70 (IQR 0.66-0.73), p < 0.001. Time to first ventilation was longer in the KLT group: median 83.00 sec (IQR 43.75-139.25 sec) than in the BMV group: median 48.00 sec (IQR 37.00-71.00 sec), p = 0.004. Times to first compression were similar: KLT median 13.00 sec (IQR 8.00-17.00 sec), BMV median 14.00 sec (IQR 11.00-18.50 sec), p = 0.331. CONCLUSION: In this randomized simulation study, KLT use by PCPs during simulated standard cardiac arrest scenarios was found to significantly increase CCF compared with basic airway management with BMV.

The impact of intense airway management training on paramedic knowledge and confidence measured before, immediately after and at 6 and 12 months after training.

INTRODUCTION: Airway management is a core component in the practice of advanced life support (ALS) paramedics. OBJECTIVE: To determine if an intense airway management course would improve ALS paramedic knowledge and confidence and if knowledge was retained over time. METHODS: An identical written survey (measuring demographics and confidence) and multiple-choice examination (measuring knowledge) was administered at the start and end of a 10 h airway course. At 6 and 12 months after the course, paramedics took the knowledge examination. Paired confidence and written knowledge examination scores before and immediately after the course were compared. Differences between knowledge examination scores at all four time points (before, immediately after and at 6 and 12 months) were tested using analysis of variance and Tukey's test. RESULTS: 299 ALS paramedics were enrolled in the study. 209 (69%) reported 6 or more years of ALS experience. The mean pre-course confidence score was 2.74/4 and the mean post-course confidence score was 3.39/4; a difference of 0.7 points (95% CI 0.61 to 0.71). Post-course examination scores improved by 4.9 points (95% CI 4.58 to 5.20), from 7.7 to 12.6/20. At 6 months the mean score was 10.3/20, and at 12 months 10.2/20. Post-course scores were significantly better than pre-course scores. Scores at 6 and 12 months did not differ significantly and remained significantly improved from pre-course scores. CONCLUSION: Significant improvement in confidence and knowledge was found after paramedics completed an intense airway management course. Knowledge at 6 and 12 months remained significantly better compared with pre-course.

Evaluating the Impact of a Novel Mobile Care Team on the Prevalence of Ambulatory Care Sensitive Conditions Presenting to Emergency Medical Services in Nova Scotia.

INTRODUCTION: Hospitalization due to ambulatory care sensitive conditions (ACSC) is a proxy measure for access to primary care. Emergency Medical Services (EMS) are increasingly called when primary care cannot be accessed. A novel paramedic-nurse EMS Mobile Care Team (MCT) was implemented in an under-serviced community. The MCT responds in a non-transport unit to referrals from EMS, emergency and primary care, and to low-acuity 911 calls in a defined geographic region. Our objective was to compare the prevalence of ACSC in ground ambulance (GA) responses before and after the introduction of the MCT. METHODS: A cross-sectional analysis of GA and MCT patients with ACSC (determined by chief complaint, clinical impression, treatment protocol, and medical history) from one year pre-MCT implementation to one year post-MCT implementation was conducted for the period of October 1, 2012, to September 30, 2014. Demographics were described. ACSC prevalence was compared using the chi-squared test. RESULTS: There were 975 calls pre-MCT and 1208 GA/95 MCT calls post-MCT. ACSC in GA patients pre- and post-MCT was similar: n=122, 12.5% vs. n=185, 15.3%; p=0.06. ACSC in patients seen by EMS (GA plus MCT) increased in the post-MCT period: 122 (12.5%) vs. 204 (15.7%) p=0.04. Pre-MCT implementation vs post-implementation, GA ACSC calls differed significantly by sex with higher female utilization (n=50 vs. n=105; p=0.007), but not age (65.38, ± 15.12 vs. 62.51 ± 20.48; p=0.16). Post-MCT, the prevalence of specific ACSC increased for GA: hypertension (p<0.001) and congestive heart failure (p=0.04). MCT patients with ACSC were less likely to have a primary care provider compared to GA (90.2% and 87.6% vs. 63.2%; p=0.003, p=0.004). CONCLUSION: The prevalence of ACSC did not decrease for GA with the introduction of the MCT, but ACSC in the overall patient population served by EMS increased. It is possible more patients with ACSC call, or are referred to EMS, for the new MCT service. Given that MCT patients were less likely to have a primary care provider, this may represent an increase in access to care or a shift away from other emergency/episodic care. These associations must be further studied to inform the ideal utility of adding such services to EMS and healthcare systems.

Clinical Roles in the Medical Communications Centre: A Rapid Scoping Review.

In recent years, 911 call volumes have increased, and emergency medical services (EMS) are routinely stretched beyond capacity. To better match resources with patient needs, some EMS systems have integrated clinician roles into the emergency medical communications centre (MCC). Our objective was to explore the nature and scope of clinical roles in emergency MCCs. Using a rapid scoping review methodology, we searched PubMed for studies related to any clinical role employed within an emergency MCC. We accepted reviews, experimental and observational designs, as well as expert opinions. Studies reporting on dispatcher recognition and pre-arrival instructions were excluded. Title and abstract screening were conducted by a single reviewer, included studies were verified by two reviewers, and data extraction was completed in duplicate, all using Covidence review software. The level of evidence was assessed using the prehospital evidence-based practice (PEP) scale. The protocol was registered in Open Science Framework (10.17605/OSF.IO/NX4T8).  Our search yielded 1071 titles, and four were added from other sources; 44 studies were reviewed at the full-text stage and 31 were included. The included studies were published from 2002 to 2022 and represent 17 countries. Studies meeting inclusion criteria consisted of level I (n=4, 11%), II (n=13, 37%), and III (N=6, 17%) methodologies, as well as 12 other studies (34%) with qualitative or other designs. Most of the included studies reported systems that employ nurses in the MCC (n=29, 83%). Twelve (34%) studies reported on the inclusion of paramedics in the MCC, and five (14%) reported physician involvement. The roles of these clinicians chiefly consisted of triage (n=25, 71%), advice (n=20, 57%), referral to non-emergency care (n=14, 40%), and peer-to-peer consulting (n=2, 4%). Alternative dispositions (as opposed to emergency ambulance transport) for low acuity callers included self-care, as well as referral to a general practitioner, pharmacist, or other outreach programs. There is a wide range of literature reporting on clinical roles integrated within MCCs. Our findings revealed that MCC nurses, physicians, and paramedics assist substantively with triage, advice, and referrals to better match resources to patient needs, with or without the requirement for ambulance dispatch.

Paramedic supportive discharge programmes to improve health system efficiency and patient outcomes: a scoping review protocol.

INTRODUCTION: Discharging older adults with frailty home from the emergency department (ED) poses unique challenges due to multiple interacting physical and social problems. Paramedic supportive discharge services help overcome these challenges by adding in-home assessment and/or interventions. Our objective is to describe existing paramedic programmes designed to support discharge from the ED or hospital to avoid unnecessary hospital admissions. A comprehensive description of paramedic supportive discharge services will be conducted by mapping the literature to describe: (1) why such programmes are needed; (2) who is being targeted, making referrals and delivering the services and (3) what assessments and interventions are offered. METHODS AND ANALYSIS: We will include studies that focus on expanded paramedic roles (community paramedicine) and extended scope postdischarge from the ED or hospital. All study designs will be included with no limit by language. We will include peer-reviewed articles and preprints and a targeted search of grey literature from January 2000 to June 2022. The proposed scoping review will be conducted in accordance with the Joanna Briggs Institute methodology. We will use a search strategy designed by a health science librarian to search MEDLINE All (Ovid), CINAHL Full Text (EBSCO), Embase (Elsevier) and Scopus (Elsevier) for eligible studies from 2000 to present. Two independent reviewers will conduct screening and full-text review. Data extraction will be conducted by one reviewer and verified by another. We will report our findings descriptively by charting trends in the research. ETHICS AND DISSEMINATION: Research ethics review is not required as this is a scoping review comprised published studies. The results of this research will be published in a manuscript and presented at national and international geriatric and emergency medicine conferences. This research will inform future implementation studies on community paramedic supportive discharge services. REGISTRATION: This scoping review protocol was registered in Open Science Framework and can be found here: https://doi.org/10.17605/OSF.IO/X52P7.

Paramedic Endotracheal Intubation Success Rates Before and After an Intensive Airway Management Education Session.

Introduction Advanced airway management by paramedics is potentially life-saving, but carries a significant risk to patient safety and can be associated with poor clinical outcome if performed incorrectly. Previously, our team had found that an intensive education intervention demonstrated an improvement in paramedic performance on a written exam and increased confidence in airway skills. This study measured intubation success and the number of attempts per patient before and after intensive paramedic airway management education intervention. Methods A 10-hour mandatory course was taken by all advanced life support (ALS) paramedics in a provincial system (2009/04-07, n=~395). The course was done during semi-annual continuing education Emergency Health Services (EHS) in-services. These day-long courses were held in person over four months. The electronic charting database was queried for intubation attempts and successful placements 12 months before the training, during the four months of training, and 12 months post-training. The primary outcome is the difference in success rates between the before (pre-intervention) and after (post-intervention) periods. The secondary outcome is the number of attempts per patient. Stationarity of success in pre- and post-periods was tested. The model was fit tested using Maximum Likelihood regression, and variables were tested using the Wald test. Results A sample size of 476 intubation attempts in each of the pre- and post-periods was required to detect a 10% improvement with the pre-intervention success of 60%. A total of 1421 intubation attempts occurred; 674 pre-intervention, 604 post-intervention, and 143 during teaching. Seven attempts were excluded (success unknown). Intubation success rates improved, from 0.68 (95% CI 0.64-0.71) to 0.75 (95% CI 0.72-0.78); a difference of 0.076 (95% CI 0.03-0.12) (p = 0.001). Intubation success rates in the pre-intervention and post-intervention periods were found to be static. A significant decrease was found in the number of attempts per patient in the post-period (p = 0.005). Conclusion Intubation success increased from 68% to 75% and was maintained over the 12-month post-period. There is a potential that judgment may also have improved, based on the decreased number of attempts per patient. Limitations include missing values, paramedics' self-reported number of attempts, and the definition of what is considered to be an attempt. In addition to previously demonstrated improvements in paramedic exam and scenario performance, this airway education intervention appears to have made a significant improvement to patient outcomes. These findings support the value of such education interventions to improve performance.

Providing palliative care at home aligns with the professional identity of paramedics: a qualitative study of paramedics and palliative health care providers.

BACKGROUND: An innovative program, 'Paramedics Providing Palliative Care at Home,' was implemented in Nova Scotia, Canada in 2015. Roles like this are part of an evolving professional identity; role discordance or lack of clarity not only hinders professionalization but may impair the wellbeing, and career longevity of paramedics. This study explored the alignment of providing palliative support at home with paramedic professional identity. METHODS: Qualitative description was employed, with thematic analysis of focus groups with paramedics and palliative health care providers. Recruitment posters were sent through the professional college (paramedics) and program managers (health care providers). Focus groups followed a semi-structured guide, discussing understanding of and experiences with the role and its alignment with professional identity. Challenges to paramedic palliative support and fit with professional identify were explored. Thematic content analysis was ongoing while focus groups were being conducted, until no new codes were found. Codes were combined, sorted into categories, and ultimately, agreed-upon themes. Saturation of themes was reached. RESULTS: Eleven paramedics and twenty palliative health care providers participated. Four themes reflected paramedic's expanded role: (1) patient centeredness and job satisfaction with provision of palliative support, (2) a bridging role, (3) paramedic as advocate and educator, (4) provision of psychosocial support. Four themes reflected paramedic's professional identity: (1) evolution of paramedicine as a skilled clinical profession, (2) helping people and communities, (3) paramedic skill set aligns with work in palliative care, and (4) changing paramedic mindset. CONCLUSION: Paramedics and palliative health care providers highlighted the provision of palliative care as part of a positive growth of paramedicine as a health profession, and a good fit with professional identity. Novel roles like this are important in the evolution of our health care system faced with increasing pressures to get the right care with the right provider at the right time.

RéSUMé: CONTEXTE: Un programme innovant, " Programme de soins palliatifs paramédicaux à domicile ", a été mis en œuvre en Nouvelle-Écosse, au Canada, en 2015. Les rôles de ce type font partie d'une identité professionnelle en évolution ; la discordance ou le manque de clarté des rôles non seulement entrave la professionnalisation, mais peut aussi nuire au bien-être et à la longévité de la carrière des ambulanciers paramédicaux. Cette étude a exploré l'alignement de la prestation de soutien palliatifs à domicile avec l'identité professionnelle des ambulanciers paramédicaux. MéTHODES: Une description qualitative a été employée, avec une analyse thématique de groupes de discussion avec des ambulanciers paramédicaux et des prestataires de soins palliatifs. Des affiches de recrutement ont été envoyées par le biais du collège professionnel (paramédicaux) et des gestionnaires de programmes (prestataires de soins de santé). Les groupes de discussion ont suivi un guide semi-structuré, discutant de la compréhension et des expériences du rôle et de son alignement avec l'identité professionnelle. Les défis du soutien palliatif paramédical et son adéquation avec l'identité professionnelle ont été explorés. L'analyse du contenu thématique s'est poursuivie pendant la tenue des groupes de discussion, jusqu'à ce qu'aucun nouveau code ne soit trouvé. Les codes ont été combinés, triés en catégories et, finalement, en thèmes convenus. La saturation des thèmes a été atteinte. RéSULTATS: Onze ambulanciers paramédicaux et vingt prestataires de soins palliatifs ont participé. Quatre thèmes reflétaient le rôle élargi des ambulanciers paramédicaux : 1) l'orientation vers le patient et la satisfaction professionnelle à l'égard de la prestation de soutien palliatifs, 2) un rôle de transition, 3) les ambulanciers paramédicaux à titre de défenseurs et d'éducateurs, 4) un soutien psychosocial. Quatre thèmes reflétaient l'identité professionnelle des ambulanciers paramédicaux : 1) l'évolution de la profession paramédicale en tant que profession clinique qualifiée, 2) l'aide aux personnes et aux collectivités, 3) l'ensemble des compétences des ambulanciers paramédicaux s'harmonise avec le travail en soins palliatifs, et 4) l'évolution de l'état d'esprit des ambulanciers paramédicaux. CONCLUSION: Les ambulanciers paramédicaux et les prestataires de soins palliatifs ont souligné que la prestation de soins palliatifs faisait partie d'une croissance positive de la profession paramédicale en tant que profession de la santé et correspondait bien à l'identité professionnelle. Des rôles novateurs comme celui-ci sont importants dans l'évolution de notre système de soins de santé, confronté à des pressions croissantes pour obtenir les bons soins auprès du bon prestataire au bon moment.

Potential Candidates for Emergency Department Initiated Extracorporeal Cardiopulmonary Resuscitation (ECPR) in a Canadian Institution.

Introduction Out-of-hospital cardiac arrest (OHCA) patients experience poor survival. The use of extracorporeal membrane oxygenation (ECMO), a form of heart-lung bypass, in the setting of cardiac arrest, termed extracorporeal cardiopulmonary resuscitation (ECPR), has promise in improving survival with good neurologic outcomes. The study objective was to determine the number of potential annual ECPR candidates among the OHCA population in a health region within the Atlantic Canadian province of Nova Scotia. Methods A retrospective chart review was conducted over a five-year period: January 1st, 2012 to December 31st, 2016. Consecutive non-traumatic OHCA and emergency department (ED) cardiac arrests occurring in a pre-determined catchment area (20-minute transport to ECMO center) defined by a geographic bounding box were identified. Criteria for ECPR were developed to identify candidates for activation of a "Code ECPR": (1) age 16-70, (2) witnessed arrest, (3) no flow duration (time to CPR, including bystander) <10 minutes, (4) resuscitation >10 minutes without return of spontaneous circulation (ROSC), (5) emergency medical service (EMS) transport to hospital <20 minutes, (6) no patient factors precluding ongoing resuscitation (do not resuscitate status (DNR), palliative care involvement, or metastatic cancer), and (7) initial rhythm not asystole. Candidates were stratified by initial rhythm. Candidates were considered ultimately ED ECPR eligible if they failed conventional treatment, defined by death or resuscitation >30 minutes. Clinical data related to candidacy was extracted by an electronic query from prehospital and ED electronic records and manual chart review by three researchers. Results Our search yielded 561 cases of EMS-treated OHCA or in-ED arrests. Of those 204/561 (36%; 95% CI 33-40%) met the criteria for activation of a "Code ECPR". Ultimately 79/204 (34%; 95% CI 28-41%) of those who met activation criteria were considered ED ECPR eligible; which is 14% (95% CI 11-17%) of the total number of arrests-of the total number of arrests, the initial rhythms were pulseless electrical activity (PEA) 33/79 (42%; 95% CI 32-53%) and shockable 46/79 (58%; 95% CI 47-69%). Conclusion Of all cardiac arrests in the area surrounding our ECMO center, approximately 41 per year met the criteria for a Code ECPR activation, with 16 per year ultimately being eligible for ED ECPR. This annual estimate varies based on the inclusion of initial rhythm. This provides insight into both prehospital and hospital implications of an ED ECPR program and will help guide the establishment of a program within our Nova Scotian health region. This study also provides a framework for similar investigation at other institutions contemplating ED ECPR program implementation.

Essential Elements to Implementing a Paramedic Palliative Model of Care: An Application of the Consolidated Framework for Implementation Research.

Background: Comfort care without transport to hospital was not traditionally a paramedic practice. The novel Paramedics Providing Palliative Care at Home Program includes a new clinical practice guideline, medications, a database to manage and share goals of care, and palliative care training. This study determined essential elements for implementation, scale, and spread of this Program. Methods: Deliberative dialogs, a qualitative method, were held with diverse stakeholders/experts in one province with the Program (Nova Scotia, March 2018) and one without (British Columbia, July 2018). The Consolidated Framework for Implementation Research (CFIR) informed the discussion guide and was used in a framework analysis. Four team members analyzed the data independently; themes were derived by consensus with the broader research team. Results: CFIR constructs framed several key elements. Inter-sectoral communication is critical but challenged by privacy concerns and the siloed structure of the health system. Locally adapted training is an essential characteristic of the intervention; cost is a factor. A shift in mindset away from traditional paramedic roles is required; this can be facilitated by paramedic champions and a positive implementation climate. Early engagement of diverse stakeholders and planning for sustainability is key. Conclusion: This framework analysis using CFIR constructs can guide successful scale and spread of the program. The constructs of Outer setting: Cosmopolitanism; Characteristics of the intervention: Adaptability; Inner Setting: Implementation climate; and Processes: Engagement, and Planning, emerged as essential.

Urban-Rural Differences in Cardiac Arrest Outcomes: A Retrospective Population-Based Cohort Study.

Background: Approximately 10% of people who suffer an out-of-hospital cardiac arrest (OHCA) treated by paramedics survive to hospital discharge. Survival differs by up to 19.2% between urban centres and rural areas. Our goal was to investigate the differences in OHCA survival between urban centres and rural areas. Methods: This was a retrospective cohort study of OHCA patients treated by Nova Scotia Emergency Medical Services (EMS) in 2017. Cases of traumatic, expected, and noncardiac OHCA were excluded. Data were collected from the Emergency Health Service electronic patient care record system and the discharge abstract database. Geographic information system analysis classified cases as being in urban centres (population > 1000 people) or rural areas, using 2016 Canadian Census boundaries. The primary outcome was survival to hospital discharge. Multivariable logistic regression covariates were age, sex, bystander resuscitation, whether the arrest was witnessed, public location, and preceding symptoms. Results: A total of 510 OHCAs treated by Nova Scotia Emergency Medical Services were included for analysis. A total of 12% (n = 62) survived to discharge. Patients with OHCAs in urban centres were 107% more likely to survive than those with OHCAs in rural areas (adjusted odds ratio = 2.1; 95% confidence interval = 1.1 to 3.8; P = 0.028). OHCAs in urban centres had a significantly shorter mean time to defibrillation of shockable rhythm (11.2 minutes ± 6.2) vs those in rural areas (17.5 minutes ± 17.3). Conclusions: Nova Scotia has an urban vs rural disparity in OHCA care that is also seen in densely populated OHCA centres. Survival is improved in urban centres. Further improvements in overall survival, especially in rural areas, may arise from community engagement in OHCA recognition and optimized healthcare delivery.

Contexte: Environ 10 % des personnes qui subissent un arrêt cardiaque en milieu extrahospitalier (ACEH), traité par des intervenants paramédicaux, survivent jusqu'à leur congé de l'hôpital. Le taux de survie peut différer de 19,2 % entre les centres urbains et les régions rurales. Notre étude visait à étudier les différences en matière de survie après un ACEH entre les centres urbains et les régions rurales. Méthodologie: Il s'agissait d'une étude de cohorte rétrospective portant sur des patients ayant subi un ACEH traité par les services médicaux d'urgence de la Nouvelle-Écosse en 2017. Les cas d'ACEH traumatique, prévu et non cardiaque ont été exclus. Les données ont été recueillies à partir du système de dossiers électroniques de soins aux patients des services médicaux d'urgence et de la Base de données sur les congés des patients. L'analyse du système d'information géographique a classé les cas selon qu'ils sont survenus dans un centre urbain (population de plus de 1 000 personnes) ou dans une région rurale, en utilisant les limites du recensement canadien de 2016. Le principal paramètre d'évaluation était la survie à la sortie de l'hôpital. Les covariables utilisées dans la régression logistique multivariée étaient l'âge, le sexe, la réanimation effectuée par des témoins si présents lors de l'arrêt cardiaque, l'emplacement public et les symptômes précédents. Résultats: Au total, 510 ACEH traités par les services médicaux d'urgence de la Nouvelle-Écosse ont été inclus aux fins de l'analyse. En tout, 12 % (n = 62) des sujets ont survécu jusqu'à leur congé hospitalier. Les patients ayant subi un ACEH dans un centre urbain étaient 107 % plus susceptibles de survivre que ceux ayant subi un ACEH dans une région rurale (rapport de cotes ajusté : 2,1; intervalle de confiance à 95 % : 1,1 ­ 3,8; p = 0,028). Le temps moyen de délivrance d'un choc lors d'un ACEH avec rythme défibrillable est significativement plus court (11,2 ± 6,2 minutes) dans un centre urbain que dans une région rurale (17,5 ± 17,3 minutes). Conclusions: La Nouvelle-Écosse fait état d'une disparité dans les soins de l'ACEH entre les régions urbaines et les régions rurales, que l'on observe également dans les villes densément peuplées. La survie est plus longue dans les centres urbains. Il est possible de prolonger davantage la survie globale, en particulier dans les régions rurales, en sensibilisant la communauté à l'ACEH et en optimisant la prestation des soins de santé.

Ambulance diversion and emergency department offload delay: resource document for the National Association of EMS Physicians position statement.

The emergency medical services (EMS) system is a component of a larger health care safety net and a key component of an integrated emergency health care system. EMS systems, and their patients, are significantly impacted by emergency department (ED) crowding. While protocols designed to limit ambulance diversion may be effective at limiting time on divert status, without correcting overall hospital throughput these protocols may have a negative effect on ED crowding and the EMS system. Ambulance offload delay, the time it takes to transfer a patient to an ED stretcher and for the ED staff to assume the responsibility of the care of the patient, may have more impact on ambulance turnaround time than ambulance diversion. EMS administrators and medical directors should work with hospital administrators, ED staff, and ED administrators to improve the overall efficiency of the system, focusing on the time it takes to get ambulances back into service, and therefore must monitor and address both ambulance diversions and ambulance offload delay. This paper is the resource document for the National Association of EMS Physicians position statement on ambulance diversion and ED offload time. Key words: ambulance; EMS; diversion; bypass; offload; delay.

Methodology for the development of a Canadian national EMS research agenda.

BACKGROUND: Many health care disciplines use evidence-based decision making to improve patient care and system performance. While the amount and quality of emergency medical services (EMS) research in Canada has increased over the past two decades, there has not been a unified national plan to enable research, ensure efficient use of research resources, guide funding decisions and build capacity in EMS research. Other countries have used research agendas to identify barriers and opportunities in EMS research and define national research priorities. The objective of this project is to develop a national EMS research agenda for Canada that will: 1) explore what barriers to EMS research currently exist, 2) identify current strengths and opportunities that may be of benefit to advancing EMS research, 3) make recommendations to overcome barriers and capitalize on opportunities, and 4) identify national EMS research priorities. METHODS/DESIGN: Paramedics, educators, EMS managers, medical directors, researchers and other key stakeholders from across Canada will be purposefully recruited to participate in this mixed methods study, which consists of three phases: 1) qualitative interviews with a selection of the study participants, who will be asked about their experience and opinions about the four study objectives, 2) a facilitated roundtable discussion, in which all participants will explore and discuss the study objectives, and 3) an online Delphi consensus survey, in which all participants will be asked to score the importance of each topic discovered during the interviews and roundtable as they relate to the study objectives. Results will be analyzed to determine the level of consensus achieved for each topic. DISCUSSION: A mixed methods approach will be used to address the four study objectives. We anticipate that the keys to success will be: 1) ensuring a representative sample of EMS stakeholders, 2) fostering an open and collaborative roundtable discussion, and 3) adhering to a predefined approach to measure consensus on each topic. Steps have been taken in the methodology to address each of these a priori concerns.
