Nasal high flow therapy for bronchiolitis.

AIM: Uptake of nasal high-flow therapy in infants with bronchiolitis has grown in the last decade with some evidence suggesting a reduction in escalation of care. The effect of the implementation of recent available evidence on clinical practice remains unclear. METHODS: In a prospective observational study over 6 months in six metropolitan hospitals in Australia, we investigated the clinical practice of high-flow in infants admitted with bronchiolitis and an oxygen requirement. To assess the choice by clinicians of the initial oxygen therapy (standard oxygen or high-flow) the disease severity was measured by physiological parameters obtained prior to oxygen therapy commencement. Additional secondary outcomes were hospital length of stay and transfers to intensive care. RESULTS: Two hundred thirty-five infants with bronchiolitis were admitted for oxygen therapy over 6 months during the winter season. Infants who received high-flow on admission to hospital displayed significantly higher respiratory rates, higher heart rates and higher early warning tool scores with more severe work of breathing than those commenced on standard oxygen therapy as a first line of oxygen therapy. A significantly longer hospital length of stay of 0.6 days occurred in infants commenced on high-flow. A significantly greater proportion on high-flow (23.3%) were admitted to intensive care compared to infants commenced on SOT (10.4%) despite the severity of disease in both groups being similar. CONCLUSIONS: Infants with bronchiolitis presenting with greater disease severity are more likely to receive high-flow therapy. Escalation of care in an intensive care unit occurred more frequently on infants on high-flow.

Evaluating patients presenting to the emergency department after syncope: validation of the Canadian Syncope Risk Score.

BACKGROUND: Syncope is a common problem but can have any of a broad range of underlying causes. Initial evaluation of the patient in the emergency department often does not identify a specific cause, and the cornerstone of management is reliable risk stratification with clinical decision rules. OBJECTIVES: The primary objective is to validate the utility and safety of the Canadian Syncope Risk Score (CSRS) as a clinical decision rule when assessing patients who present with syncope to Australian emergency departments. Our secondary objective is to evaluate the economic benefits of diverting patients with syncope at low risk of serious adverse events from admission to hospital. METHODS AND ANALYSIS: Prospective, observational study. Patients aged 18 years or more who present to the emergency department (ED) after syncope in the preceding 24 hours and have returned to their baseline state will be enrolled. Patients will be contacted by telephone to determine whether they have experienced any adverse events within 30 days of their initial presentation to the ED. The CSRS will be applied retrospectively to determine the relationship between whether patients were admitted to hospital or discharged home and the reporting of serious adverse events for each CSRS risk level. We will also undertake a cost-effectiveness analysis from the health care perspective. ETHICS APPROVAL: Prince Charles Hospital Human Research Ethics Committee (reference, HREC/17/QPCH/48). DISSEMINATION OF RESULTS: Outcomes will be disseminated by Queensland Health and the funding body via social media, presented at local and national emergency medicine conferences, and published in international emergency medicine and health economics journals. CLINICAL TRIALS REGISTRATION: Not applicable.

Potential role of general practice in reducing emergency department demand: A qualitative study.

OBJECTIVE: To inform local, state and national strategies intended to reduce demand for ED care, the present study aimed to identify key factors influencing the current provision of acute care within primary healthcare (PHC) and explore the policy and system changes potentially required. METHODS: Semi-structured interviews with key stakeholders were audio-recorded, transcribed verbatim and analysed through content and thematic approaches incorporating the Walt and Gilson health policy framework. RESULTS: Eleven interviews were conducted. Five key considerations were highlighted, namely the barriers and enablers for general practitioners (GPs) in providing acute care, barriers to patient use of PHC instead of ED, suggestions for new PHC models and improvements for current ED models. Additionally, economic issues relating to clinic funding and GP remuneration, complexities of state or federal funding and management of urgent care centres (UCC) were identified. Potential policy changes included GP clinics incorporating emergency appointments, GP triage, further patient streaming and changes to the ED medical workforce model, as well as linking hospitals with PHC clinics. Suggested system changes included improving rapid access to non-GP specialists, offering qualifications for urgent care within PHC, developing integrated information technology systems and educating patients regarding appropriate healthcare system pathways. CONCLUSION: The present study suggested that while PHC has the potential to attenuate the demands for ED services, a whole-of-system approach focusing on realignment of priorities and integrated changes are needed.

Acceptability of emergency department triage nurse's advice for patients to attend general practice: A cross-sectional survey.

OBJECTIVES: Demand for ED care is increasing at a rate higher than population growth. Strategies to attenuate ED demands include diverting low-acuity general practice-type ED attendees to alternate primary healthcare settings. The present study assessed the ED attendees' receptiveness to accept triage nurse's face-to-face advice to explore alternate options for medical care and what factors influence the level of acceptance. METHODS: The ED attendees of four major public hospital EDs in Brisbane were surveyed between August and October 2018, using a questionnaire informed by Health Belief Model's cues to action. RESULTS: Of the 514 valid responses, 81% of respondents were very likely/likely to accept the triage nurse's advice to see a general practitioner. Self-perceived urgency of presenting condition/s (odds ratio [OR] 0.87, 95% confidence interval [CI] 0.78-0.97), not having confidence in general practitioner (OR 0.37, 95% CI 0.21-0.66) and having a medical record at the hospital (OR 0.60, 95% CI 0.36-0.99) were negatively associated with the likelihood of accepting the advice. For every point increase in perceived seriousness, the odds of accepting the advice decreased by 16% (95% CI 6-25%). CONCLUSION: Most of the participants believed that EDs were for emergent care and they attended the ED because they perceived their presenting condition/s to be serious and/or urgent. The acceptability of face-to-face advice by triage nurse to seek help in general practice was influenced by perceived threats of the illness, and the underlying beliefs about availability, accessibility, suitability and affordability of the service.

Experience with a Clinical Audit Requirement for Interns in the Emergency Department.

BACKGROUND: The clinical audit is an important evaluation tool to ensure quality assurance. A clinical audit requirement for interns during their emergency department (ED) term may be a valuable educational activity. METHODS: The Emergency Audit Initiative (EAI) Program was initiated at Redcliffe Hospital in January 2018. Interns, who were paired with a staff specialist audit mentor, chose a topic of interest and carried out a clinical audit during their 10-week ED term. At the end of term, interns formally presented audit findings in a grand round setting. Interns and staff specialists were surveyed at the end of the intern year regarding aspects of the program. Surveys aimed to assess: (1) value of the program as an educational activity, (2) availability of time and resources to conduct the audit, and (3) perceived impact on practice. RESULTS: During the first year of the program, 27 clinical audits were carried out. 16 interns (59%) and 8 staff specialists (57%) responded to the surveys. Interns and staff specialists reported that the audit was a valuable educational experience (88% and 100%). Interns also reported that they had adequate time (94%) and resources (81%) to conduct the audit. Interns and staff specialists however reported only a modest impact on clinical practice because of the audit program. CONCLUSIONS: Our experience with the EAI program suggests that incorporating a clinical audit requirement into the ED term is possible. Interns and staff specialists reported it to be a beneficial educational and professional development activity.

External validation of the Canadian Syncope Risk Score for patients presenting with undifferentiated syncope to the emergency department.

OBJECTIVE: To validate the accuracy and safety of the Canadian Syncope Risk Score (CSRS) for patients presenting with syncope. METHODS: Single centre prospective observational study in Brisbane, Australia. Adults presenting to the ED with syncope within the last 24 h were recruited after applying exclusion criteria. Study was conducted over 1 year, from March 2018 to March 2019. Thirty-day serious adverse events (SAE) were reported based on the original derivation study and standardised outcome reporting for syncope. Individual patient CSRS was calculated and correlated with 30-day SAE and disposition status from ED. RESULTS: Two hundred and eighty-three patients were recruited to the study. Average age was 55.6 years (SD 22.7 years), 37.1% being male with a 39.9% admission rate. Thirty-day SAE occurred in seven patients (2.5%) and no recorded deaths. The CSRS performed with a sensitivity of 71.4% (95% confidence interval [CI] 30.3-94.9%), specificity 72.8% (95% CI 67.1-77.9%) for a threshold score of 1 or higher. CONCLUSION: Syncope patients in our study were predominantly very low to low risk (72%). The prevalence of 30-day SAE was low, majority occurring following hospital discharge. Sensitivity estimates for CSRS was lower than the derivation study but lacked robustness with wide CIs because of a small sample size and number of events observed. However, the CSRS did not miss any clinically relevant outcomes in low risk patients making it potentially useful in aiding their disposition. Larger validation studies in Australia are encouraged to further test the diagnostic accuracy of the CSRS.

General practitioner-type patients in emergency departments in metro North Brisbane, Queensland: A multisite study.

OBJECTIVE: To estimate the proportion of ED patients in urban Queensland who are potentially suitable for general practitioner (GP) care. METHODS: A retrospective analysis was conducted using ED Information System data from Metro North Hospital and Health Service in Brisbane, Australia for three consecutive financial years (2014-2015 to 2016-2017). The hospitals included two Principal Referral and two Public Acute hospitals. GP-type patients were calculated using the Australian Institute of Health and Welfare (AIHW), Australasian College for Emergency Medicine (ACEM) and the validated Sprivulis methods. RESULTS: Of the 822 841 ED presentations, 219 567 (27%) were potentially GP-type patients by AIHW, 49 307 (6%) by ACEM and 61 836 (8%) by Sprivulis methods. The higher proportion of GP-type presentations were during 08.00 to 17.00 hours by AIHW and ACEM methods. Of the lower-acuity triage categories of 4 (286 154 presentations) and 5 (5658 presentations), AIHW estimated that 62% and 80% of the patients were GP-type patients, as compared to 9% and 22% by ACEM, and 9% and 0.3% by Sprivulis method. The mean costs of adult GP-type patients is $345 by the AIHW and $406 by the ACEM method, lower than non-GP type patients ($706 and $622, respectively). CONCLUSIONS: There is considerable variation in what is considered GP-type ED presentations based on the three methods employed and this variation may have fuelled the debate surrounding what is 'avoidable' ED utilisation. Regardless, the study findings provide an interesting addition to defining and addressing appropriate utilisation of ED services.

Trends in access block 2011 to 2013: the Redcliffe National Emergency Access Target experience.

OBJECTIVE: To evaluate the impact of the introduction of National Emergency Access Target (NEAT) on access block and long-stay patients in Redcliffe Hospital ED, and to evaluate the possibility of forward compliance with the 2014 and 2015 NEAT thresholds. SETTING AND DESIGN: Redcliffe hospital is a major urban district hospital in Brisbane with more than 55,000 adult and paediatric patients per annum. We evaluated aggregate Emergency Department Information System data for the years 2011, 2012 and 2013 to correlate presentations, NEAT compliance, access block and the number of long-stay patients in our department. RESULTS: There has been a significant reduction in both access block and our number of long-stay patients corresponding with improvements in NEAT compliance. Our forward analysis suggests that without substantial improvements in the NEAT for admitted patients, compliance with 2014 and 2015 thresholds is unlikely to be achievable. CONCLUSIONS: NEAT has been a driver of significant improvements in access block at our institution. We see significant issues with raising the NEAT threshold to the proposed 90% in 2015, and support recent calls for re-evaluation and modification of the target.
