Paramedics commonly administer intravenous (IV) dextrose to severely hypoglycemic patients. Typically, the treatment provided is a 25g ampule of 50% dextrose (D50). This dose of D50 is meant to ensure a return to consciousness. However, this dose may cause harm and lead to difficulties regulating blood glucose levels (BGLs) post-treatment. It is hypothesized that a lower concentration, such as 10% dextrose (D10), may improve symptoms while minimizing harm.

PubMed, Embase, CINAHL, and Cochrane Central were systematically searched on September 15, 2020. The PRISMA guidelines were followed. GRADE and risk of bias were applied to determine the certainty of the evidence. Primary literature investigating the use of IV dextrose in hypoglycemic diabetic patients presenting to paramedics or the emergency department was included. Outcomes of interest included safety, efficacy (symptom resolution), and BGL.

Of 680 abstracts screened, 51 full-text articles were reviewed, with eleven studies included. Data from three randomized controlled trials (RCTs) and eight observational studies were analyzed. A single RCT comparing D10 to D50 was identified. The primary significant finding of the study was an increased post-treatment glycemic profile by 3.2mmol/L in the D50 group; no other outcomes had significant differences between groups. When comparing pooled data from all the included studies, there was greater symptom resolution in the D10 group (95.9%) compared to the D50 group (88.8%). However, the mean time to resolution was approximately four minutes longer in the D10 group (4.1 minutes [D50] versus 8.0 minutes [D10]). There was a greater need for subsequent doses with the use of D10 (19.5%) compared to D50 (8.1%). The post-treatment glycemic profile was lower in the D10 group at 6.2mmol/L versus 8.5mmol/L in the D50 group. Both treatments had nearly complete resolution of hypoglycemia: 98.7% (D50) and 99.2% (D10). No adverse events were observed in the D10 group (0/1057) compared to 13/310 adverse events in the D50 group.

Studies show D10 may be as effective as D50 at resolving symptoms and correcting hypoglycemia. Although the desired effect can take several minutes longer, there appear to be fewer adverse events. The post-D10-treatment BGL may result in fewer untoward hyperglycemic episodes.

Fibrinolysis is an acceptable treatment for acute ST-segment elevation myocardial infarction (STEMI) when primary percutaneous coronary intervention (PCI) cannot be performed within 120 minutes. The American Heart Association has recommended Emergency Medical Services (EMS) interventions such as prehospital fibrinolysis (PHF), prehospital electrocardiogram (ECG), and hospital bypass direct to PCI center. Nova Scotia, Canada has incorporated these interventions into a unique province-wide approach to STEMI care. A retrospective cohort analysis comparing the primary outcome of 30-day mortality for patients receiving either prehospital or emergency department (ED) fibrinolysis (EDF) to patients transported directly by EMS from community or regional ED for primary PCI was conducted.

This retrospective, population-based cohort study included all STEMI patients in Nova Scotia who survived to hospital admission from July 2011 through July 2013. Three provincial databases were used to collect demographic, 30-day mortality, hospital readmission, and rescue PCI data. The results were grouped and compared according to reperfusion strategy received: PHF, EDF, patients brought by ambulance via EMS direct to PCI (EMS to PCI), and ED to PCI (ED to PCI).

There were 1,071 STEMI patients included with 145 PHF, 606 EDF, 98 EMS to PCI, and 222 ED to PCI. There were no significant differences in 30-day mortality across groups (n, %): PHF 5(3); EDF 36(6); EHS to PCI <5(2); and ED to PCI 10(4); P = .28. There was no significant difference in patients receiving fibrinolysis who underwent rescue PCI.

Prehospital fibrinolysis incorporated into a province-wide approach to STEMI treatment is feasible with no observed difference in patient 30-day mortality outcomes observed.

Paramedics Providing Palliative Care at Home was launched in two provinces, including a new clinical practice guideline, database, and paramedic training. The aim of this study was to evaluate patient/family satisfaction and paramedic comfort and confidence.

In Part A, we gathered perspectives of patients/families via surveys mailed at enrolment and telephone interviews after an encounter. Responses were reported descriptively and by thematic analysis. In Part B, we surveyed paramedics online pre- and 18 months post-launch. Comfort and confidence were scored on a 4-point Likert scale, and attitudes on a 7-point Likert scale, reported as the median (interquartile range [IQR]); analysis with Wilcoxon ranked sum/thematic analysis of free text.

In Part A, 67/255 (30%) enrolment surveys were returned. Three themes emerged: fulfilling wishes, peace of mind, and feeling prepared for emergencies. In 18 post-encounter interviews, four themes emerged: 24/7 availability, paramedic professionalism and compassion, symptom relief, and a plea for program continuation. Thematic saturation was reached with little divergence. In Part B, 235/1255 (18.9%) pre- and 267 (21.3%) post-surveys were completed. Comfort with providing palliative care without transport improved post launch (p = < 0.001) as did confidence in palliative care without transport (p = < 0.001). Respondents strongly agreed that all paramedics should be able to provide basic palliative care.

After implementation of the multifaceted Paramedics Providing Palliative Care at Home Program, paramedics describe palliative care as important and rewarding. The program resulted in high patient/family satisfaction; simply registering provides peace of mind. After an encounter, families particularly noted the compassion and professionalism of the paramedics.

The Collaborative Emergency Centre (CEC) model of care was implemented in Nova Scotia without an identifiable, directly comparable precedent. It features interprofessional teams working towards the goal of providing improved access to primary health care, and appropriate access to 24/7 emergency care. One important component of CEC functioning is overnight staffing by a paramedic and registered nurse (RN) team consulting with an off-site physician. Our objective was to ascertain the attitudes, feelings and experiences of paramedics working within Nova Scotia’s CECs.

We conducted a qualitative study informed by the principles of grounded theory. Semi-structured telephone interviews were conducted with paramedics with experience working in a CEC. Analysis involved an inductive grounded approach using constant comparative analysis. Data collection and analysis continued until thematic saturation was reached.

Fourteen paramedics participated in the study. The majority were male (n=10, 71%) with a mean age of 44 years and mean paramedic experience of 14 years. Four major themes were identified: 1) interprofessional relationships, 2) leadership support, 3) value to community and 4) paramedic identity.

Paramedics report largely positive interprofessional relationships in Nova Scotia’s CECs. They expressed enjoyment working in these centres and believe this work aligns with their professional identity. High levels of patient and community satisfaction were reported. Paramedics believe future expansion of the model would benefit from development of continuing education and improved communication between leadership and front-line workers.

Societal aging is expected to impact the use of emergency medical services (EMS). Older adults are known as high users of EMS. Our primary objective was to quantify the rate of EMS use by older adults in a Canadian provincial EMS system. Our secondary objective was to compare those transported to those not transported.

We analysed data from a provincial EMS database for emergency responses between January 1, 2010 and December 31, 2010 and included all older adults (≥65 years) requesting EMS for an emergency call. We described EMS use in relation to age, sex, and resources.

There were 30,653 emergency responses for older adults in 2010, representing close to 50% of the emergency call volume and an overall response rate of 202.8 responses per 1,000 population 65 years and older. The mean age was 79.9±8.5 years for those 57.3% who were female. The median paramedic-determined Canadian Triage and Acuity Scale (CTAS) score was 3 and the mean on-scene time was 24.2 minutes. Non-transported calls (12.3%) for the elderly involved predominantly (54.9%) female patients of similar mean age (78.3 years) but lower acuity (CTAS 5) and longer average on-scene times (32.6 minutes).

We confirmed the increasingly high rate of EMS use with age to be consistent with other industrialized populations. The low-priority and non-transport calls by older adults consumed considerable resources in this provincial system and might be the areas most malleable to meet the challenges facing EMS systems.

The Comprehensive Geriatric Assessment (CGA) is used in geriatric medicine as a means to manage the health care needs of older adults and to grade frailty. We modified the CGA so that it could be completed independently by care partners (usually family) and be used to grade frailty. Our objective was to examine the feasibility of a care partner completing the CGA at the time of the first prehospital encounter.

A prospective, observational study was conducted with a convenience sample of patients ≥ 70 years accompanied by a knowledgeable care partner. Feasibility was measured by the time required and percent completeness of items on the form based on completion by the care partner and by paramedic perception of utility.

Subjects (N 5 104) were enrolled with three postenrolment exclusions due to ineligibility. Most participants were older women living in their own home. The mean time to complete the questionnaire was 18.7 minutes (SD 11.3; median 15 minutes; interquartile range 12-20 minutes). Only 64% of the care partners recorded the time it took. Nineteen percent of paramedics completed a follow-up survey, and all felt screening for frailty was worthwhile and most (> 70%) thought that the CP-CGA may be a useful approach. The study was limited by recruitment bias of potentially eligible patients, a high level of missingness in the outcome measures of interest, and low paramedic participation rates.

We observed a high rate of item completeness of questionnaires with a mean time to complete of 18.7 minutes in a convenience sample of older patients. A small sample of paramedics universally endorsed the utility of screening for frailty in the prehospital setting, and many thought the CP-CGA was a helpful tool.
