Objectives: To compare emergency medical services (EMS) utilization between culturally and linguistically diverse (CALD) and non-CALD patients in Victoria, Australia. Methods: A retrospective study of EMS attendances and transports in Victoria from January 2015 to June 2019, utilizing linked EMS, hospital emergency and admissions data. The CALD and non-CALD patients who received EMS care and transport to a Victorian public emergency department were included. The incidence of EMS use for CALD and non-CALD patients based on the 2016 Census population and expressed per 100,000 person-years. Results: In 1,261,167 included patients, there were 272,100 (21.6%) CALD and 989,067 (78.4%) non-CALD patients. Before adjustment for age and sex, EMS utilization for CALD patients was 13% lower than non-CALD patients (incidence rate ratio [IRR] 0.87, 95% CI: 0.87–0.87). When stratified by age groups, CALD patients aged under 70 years had significantly lower rates of EMS utilization than non-CALD patients, while CALD patients aged 75 years or older were more likely than non-CALD patients to use EMS (IRR 1.08, 95% CI: 1.07–1.09). The CALD patients were less likely to utilize EMS for trauma/external injury (IRR = 0.67, 95% CI: 0.66–0.68) and mental health/alcohol/drug problems (IRR = 0.39, 95% CI: 0.38–0.40). After adjustment for differences in the age and sex distribution of CALD and non-CALD populations, CALD patients were 51% less likely to utilize EMS than non-CALD patients (IRR 0.49, 95% CI: 0.42–0.56). Conclusions: The CALD patients used EMS less frequently than non-CALD patients with significant variation observed across age groups, countries of birth, and clinical presentation. Further research is needed to understand the factors that may be contributing to these disparities. [ABSTRACT FROM AUTHOR]

Objective: Many patients who are attended by paramedics do not require conveyance to an emergency department (ED). Our study focuses on comparing the characteristics and outcomes of patients who were advised to follow up with a general practitioner (GP) by an attending paramedic with those of patients who were discharged at scene or transported to hospital. Methods: This was a retrospective data linkage cohort study of ambulance, ED, hospital admission, and death records for all adults attended by paramedics in Victoria, Australia between the 1st of January 2015 and 30th of June 2019. Patients were excluded if they presented in cardiac arrest, resided in a residential aged care facility, or were receiving palliative care services. Outcomes of interest included reattendance by ambulance, ED presentation; and, a high acuity outcome which we defined as a patient who (1) presented to ED and received an Australasian Triage Scale of category 1 (Resuscitation) or 2 (Emergency) AND was admitted to a ward OR (2) was admitted to an Intensive Care Unit, Coronary Care Unit or Catheter laboratory (regardless of triage category) OR (3) died. Outcomes of interest were considered within 48-h of initial EMS attendance. Results: A total of 1,777,950 cases were included in the study of which 3.1% were referred to a GP, 9.0% were discharged at scene without a follow-up recommendation, and 87.9% were transported to hospital. Patients referred to a GP were more likely than those discharged at scene to subsequently present to an ED within 48 h of their attendance (5.3% vs 3.8%). However, GP referral was not associated with any change to high acuity outcome (0.3% vs 0.2%) or ambulance reattendance (6.0% vs 6.0%) compared to discharge at scene. The only factors that were associated with ambulance reattendance, ED presentation, and a high acuity outcome were male gender and elevated temperature. Conclusions: Despite increasing low and medium-acuity casework in this EMS system, paramedic referral to a GP is not common practice. Referring a patient to a GP did not reduce the likelihood of patients experiencing a high acuity outcome or recalling an ambulance within 48 h, suggesting opportunity exists to refine paramedic to GP referral practices.

In this investigation, we analyzed Hispanic student access and success in health-related degrees by examining enrollment and graduation rates over a period of 13 years. Archival data were obtained from the Texas Higher Education Coordinating Board consisting of the number of Hispanic students enrolled and number of degrees awarded in the health-related degrees at Texas health-related institutions for each year beginning with 2000 through 2012. Statistically significant increases were not present in the number or the percentages of Hispanic students enrolled in undergraduate degree programs or for the number or the percentages of undergraduate degrees awarded. The lack of statistically significant increases should serve as a call to examine the higher education system.

Objective: The ambulance service in Victoria, Australia implemented a revised clinical response model (CRM) in 2016 which was designed to increase the diversion of low‐acuity Triple Zero (000) calls to secondary telephone triage and reduce emergency ambulance dispatches. The present study evaluates the influence of the revised CRM on emergency ambulance response times and ED presentations. Methods: A retrospective study of emergency calls for ambulance between 1 January 2015 and 31 December 2018. Ambulance data were linked with ED presentations occurring up to 48 h after contact. Interrupted time series analyses were used to evaluate the impact of the revised CRM. Results: A total of 2 365 529 calls were included. The proportion allocated a Code 1 (time‐critical, lights/sirens) dispatch decreased from 56.6 to 41.0% after implementation of the revised CRM. The proportion of calls not receiving an emergency ambulance increased from 10.4 to 19.6%. Interrupted time series analyses demonstrated an improvement in Code 1 cases attended within 15 min (Key Performance Indicator). However, for patients with out‐of‐hospital cardiac arrest or requiring lights and sirens transport to hospital, there was no improvement in response time performance. By the end of the study period, there was also no difference in the proportion of callers presenting to ED when compared with the estimated proportion assuming the revised CRM had not been implemented. Conclusion: The revised CRM was associated with improved Code 1 response time performance. However, there was no improvement in response times for high acuity patients, and no change in the proportion of callers presenting to ED. [ABSTRACT FROM AUTHOR]

Objective: Despite high in‐hospital mortality, the epidemiology of prehospital suspected sepsis presentations is not well described. This retrospective cohort study aimed to quantify the burden of such presentations, and to determine whether such a diagnosis was independently associated with longer‐term mortality. Methods: Retrospective, observational population‐based cohort study examining all adult prehospital presentations in Victoria, between January 2015 and June 2019, who required subsequent in‐hospital assessment. Linked data were extracted from clinical and administrative datasets. Demographics, illness severity, prehospital treatment and mortality were compared between prehospital suspected sepsis and non‐sepsis patients. Multivariable logistic regression was used to determine the adjusted association between prehospital assessment (suspected sepsis vs non‐sepsis) and 6‐month mortality. Results: A total of 1 218 047 patients were included. The age‐adjusted incidence rate of prehospital suspected sepsis was 65 cases per 100 000 person‐years. Those with prehospital suspected sepsis were older (74 vs 62 years), more frequently male (55% vs 47%), with greater physiological derangement. Intravenous cannulas were more often inserted prehospital (60% vs 29%). Crude in‐hospital mortality was 6.5‐fold higher in the prehospital suspected sepsis group (11.8% vs 1.8%), and by 6 months, 22.6% had died. After adjustment for demographics, illness severity, comorbidity, treatment and hospital location, a diagnosis of prehospital suspected sepsis was associated with a 35% higher likelihood of 6‐month mortality (OR 1.35, 95% CI 1.29–1.41). Conclusions: The burden of prehospital suspected sepsis in the Australian setting is significant, with paramedics identifying patients at high‐risk of poor longer‐term outcomes. This implies the need to consider improved care pathways for this highly vulnerable group. [ABSTRACT FROM AUTHOR]

Objectives: There are currently limited data to inform the management of patients transported by emergency medical services (EMS) with dyspnoea. We aimed to describe the incidence, aetiology and outcomes of patients transported by EMS for dyspnoea using a large population-based sample and to identify factors associated with 30-day mortality. Methods: Consecutive EMS attendances for dyspnoea in Victoria, Australia from January 2015 to June 2019 were included. Data were individually linked to hospital and mortality records to determine incidence, diagnoses, and outcomes. Factors associated with 30-day mortality were assessed usingmultivariable logistic regression. Results: During the study period, there were 2 505 324 cases attended by EMS, of whom 346 228 (14%) met inclusion criteria for dyspnoea. The incidence of EMS attendances for dyspnoea was 1566 per 100 000 person-years, and was higher in females, older patients and socially disadvantaged areas. Of the 271 204 successfully linked cases (median age 76 years; 51% women), 79% required hospital admission with a 30-day mortality of 9%. The most common final diagnoses (and 30-day mortality rates) were lower respiratory tract infection (13%, mortality 11%), chronic obstructive pulmonary disease (13%, mortality 6.4%), heart failure (9.1%, mortality 9.8%), arrhythmias (3.9%, mortality 4.4%), acute coronary syndromes (3.9%, mortality 9.5%) and asthma (3.2%, mortality 0.5%). Predictors of mortality included older age, male sex, pre-existing chronic kidney disease, heart failure or cancer, abnormal respiratory status or vital signs and pre-hospital intubation. Conclusion: Dyspnoea is a common presentation with a broad range of causes and is associated with high rates of hospitalisation and death. [ABSTRACT FROM AUTHOR]

BACKGROUND The impact of age on outcomes in cardiogenic shock (CS) is poorly described in the pre-hospital setting. We assessed the impact of age on outcomes of patients treated by emergency medical services (EMS). METHODS This population-based cohort study included consecutive adult patients with CS transported to hospital by EMS. Successfully linked patients were stratified into tertiles by age (18-63, 64-77, and > 77 years). Predictors of 30-day mortality were assessed through regression analyses. The primary outcome was 30-day all-cause mortality. RESULTS A total of 3523 patients with CS were successfully linked to state health records. The average age was 68 ± 16 years and 1398 (40%) were female. Older patients were more likely to have comorbidities including pre-existing coronary artery disease, hypertension, dyslipidemia, diabetes mellitus, and cerebrovascular disease. The incidence of CS was significantly greater with increasing age (incidence rate per 100,000 person years 6.47 [95% CI: 6.1-6.8] in age 18-63 years, 34.34 [32.4-36.4] in age 64-77 years, 74.87 [70.6-79.3] in age > 77 years, P < 0.001). There was a step-wise increase in the rate of 30-day mortality with increasing age tertile. After adjustment, compared to the lowest age tertile, patients aged > 77 years had increased risk of 30-day mortality (adjusted hazard ratio = 2.26 [95% CI: 1.96-2.60]). Older patients were less likely to receive inpatient coronary angiography. CONCLUSION Older patients with EMS-treated CS have significantly higher rates of short-term mortality. The reduced rates of invasive interventions in older patients underscore the need for further development of systems of care to improve outcomes for this patient group. [ABSTRACT FROM AUTHOR]

Objectives Methods Results Conclusion Stress‐induced hyperglycaemia (SIH) is an elevated blood glucose level (≥11.1 mmol/L) in patients experiencing physiological stress, in the absence of diabetes mellitus. Although early in‐hospital SIH has been associated with worse outcomes following major trauma, the predictive value of SIH in the prehospital setting has not been established. To investigate the role of prehospital SIH as a predictor of in‐hospital mortality following major trauma.A retrospective cohort study of non‐diabetic, adult major trauma patients was undertaken to determine the association between prehospital SIH and in‐hospital mortality. Secondary outcomes included ED disposition and ED length of stay.Of 1179 trauma patients included, 89 (8%) had SIH. Prehospital SIH was associated with higher Injury Severity Scores (median (interquartile range): 25 (17–33) vs 17 (14–25)), lower GCS (GCS 3–7: 48.3% vs 10.9%, P < 0.001), lower systolic BP (mean (SD): 122 (44.0) vs 133 (30.3)), lower oxygen saturations (mean (SD): 88% (16) vs 96% (7)) and abnormal heart and respiratory rate. The in‐hospital mortality rate was 9.9% in non‐SIH patients and 42.7% among patients with SIH (odds ratio (OR): 6.8; 95% confidence interval (CI): 4.3–10.8, P < 0.001). The area under the receiver operating curve for blood glucose alone in predicting mortality was 0.65 (95% CI: 0.60–0.70). Prehospital blood glucose was an independent predictor of mortality after adjustment for age, sex, GCS and vital signs (adjusted OR = 2.9; 95% CI: 1.5–5.5, P = 0.001).The present study demonstrated an association between prehospital SIH and in‐hospital mortality following major trauma. Further prospective research is warranted to examine the utility and integration of prehospital SIH into predicting models of trauma care. [ABSTRACT FROM AUTHOR]
