Rethinking the tiered trauma team response: A case-series study in a regional trauma centre.

OBJECTIVE: To reduce perceived unnecessary resource use, we modified our tiered trauma response. If a patient was not physiologically compromised, surgical registrar attendance was not mandated. We investigated the effect of this change on missed injury, unplanned representation to ED, diagnostic imaging rates and staff satisfaction. METHODS: A retrospective case series study assessing the 3-month period before and after the intervention was conducted. Logistic regression analyses were used to examine the association between ordering of computerised tomography (CT) and ED length of stay (LOS), injury severity (ISS), age, surgical review and admission. A staff survey was conducted to investigate staff perceptions of the practice change. Free text data were analysed using inductive content analysis. RESULTS: There were 105 patients in the control and 166 in the intervention group and their mean (SD) ISS was the same (ISS [SD] = 4 [±4] [P = 0.608]). A higher proportion of the control group were admitted (56.3% vs 42.2% [P = 0.032]) and they had a shorter ED LOS (274 min [202-456] vs 326 min [225-560], P = 0.044). The rate of missed injury was unchanged. A surgical review resulted in a 26-fold increase in receipt of a whole-body CT scan (odds ratio = 26.89, 95% confidence interval = 3.31-218.17). Just over half of survey respondents felt the change was safe (54.4%), and more surgical (90%) than ED staff (69%) reported the change as positive. CONCLUSION: The removal of the surgical registrar from the initial trauma standby response did not result in any adverse events, reduced admissions, pathology and imaging, but resulted in an increased ED LOS and time to surgical review.

Factors that contribute to patient length of stay in the emergency department: A time in motion observational study.

OBJECTIVES: Increased Emergency Department length of stay impacts access to emergency care and is associated with increased patient morbidity, overcrowding, reduced patient and staff satisfaction. We sought to determine the contributing factors to increased length of stay in our mixed ED. METHODS: A real-time observational study was conducted at Wollongong Hospital over a continuous 72-h period. Times of intervention, assessment and treatment were recorded by dedicated emergency medical or nurse observers. The time from triage to each event was calculated and descriptive analyses performed. Free text comments were analysed using inductive content analysis. RESULTS: Data were collected on 381 of 389 eligible patients. The largest time delays were experienced by patients who required a CT, specialist review and/or an inpatient bed. Registrars and nurse practitioners were the most efficient in reaching a decision to admit or discharge. The time from triage to specialist review increased with the number requested (148 min for one, 224 min for two and 285 min for three). The longest length of stay was experienced by mental health and paediatric patients. CONCLUSIONS: The main delays contributing to ED length of stay were CT imaging and specialist reviews. Overcrowding in ED need targeted, site-specific interventions.

Development of an Early Activation Hip Fracture Care Bundle and Implementation Strategy to Improve Adherence to the National Hip Fracture Clinical Care Standard.

OBJECTIVE: To develop and implement a multidisciplinary early activation mechanism and bundle of care (eHIP) to improve adherence to ACSQHC standards in a regional trauma centre. METHODS: Barriers to implementation were categorised using the Theoretical Domains Framework, then linked to specific strategies guided by the Behaviour Change Wheel and Behaviour Change Technique Taxonomy (BCTT). The resulting implementation strategies were assessed using Affordable, Practical, Effective, Acceptable, had Side-effects (APEASE) criteria. RESULTS: Eighty-three barriers to implementation of the hip fracture care bundle were identified. The behaviour change wheel process resulted in the identification of 41 techniques to address these barriers. The predominant mechanisms to achieve this were development and implementation of 1) formal policy that outlines eHIP roles; 2) video promotion; 3) pager group; 4) fascia iliaca block enabling; 5) eMR modifications; 6) face-to-face reinforcement and modelling; 7) communication and prompts; 8) environmental restructuring. CONCLUSION: We applied behaviour change theory through a pragmatic evidence-based process. This resulted in a codesigned strategy to overcome staff and organisational barriers to the implementation of a multidisciplinary early activation mechanism and bundle of care (eHIP). Future work will include evaluation of the uptake and clinical impact of the care bundle.

Randomised trial of the fascia iliaca block versus the '3-in-1' block for femoral neck fractures in the emergency department.

INTRODUCTION: Femoral neck fractures are a common and painful injury. Femoral nerve blocks, and a variant of this technique termed the '3-in-1' block, are often used in this patient group, but their effect is variable. The fascia iliaca compartment block (FIB) has been proposed as an alternative, but the relative effectiveness of the two techniques in the early stages of care is unknown. We therefore compared the FIB versus the 3-in-1 block in a randomised trial conducted in two UK emergency departments. METHODS: Parallel, two-group randomised equivalence trial. Consenting patients >18 years with a femoral neck fracture were randomly allocated to receive either a FIB or a 3-in-1 block. The primary outcome was pain measured on a 100 mm visual analogue scale at 60 min. The between-group difference was adjusted for centre, age, sex, fracture type, pre-block analgesia and pre-block pain score. RESULTS: 178 patients were randomised and 162 included in the primary analysis. The mean 100 mm visual analogue pain scale score at 60 min was 38 mm in the FIB arm and 35 mm in the 3-in-1 arm. The adjusted difference between the arms was 3 mm, with a 95% CI (-4.7 to 10.8) that excluded a clinically important difference between the two interventions. CONCLUSIONS: FIB is equivalent to the 3-in-1 block for immediate pain relief in adult neck of femur fractures. TRIAL REGISTRATION NUMBER: ISRCTN16152419.

Case of the month: "Oh! Drat!--A case of transcutaneous superwarfarin poisoning and its recurrent presentation".

Superwarfarin poisoning is considered a significant public health problem in the US. In 2004, there were 16,054 cases of poisoning; most were accidental ingestions of rat bait by children but 4576 patients required hospital treatment, 23 patients had major adverse outcomes and 1 patient died. Similar information is unavailable for the UK. The National Poisons Information Service is presently auditing cases. The case of a farmer who presented with haematuria, 9 days after spilling a rodenticide containing a superwarfarin over himself is reported here. He was physically well except for mild abdominal tenderness. He had grossly deranged clotting studies (prothrombin time (PT) >200 s, activated partial thromboplastin time (APTT) 56 s) that were rapidly corrected with fresh frozen plasma and vitamin K. He was sent home after 5 days without follow up. Unfortunately, he presented again 2 days later, again with haematuria and an international normalised ratio (INR) >10. He required inpatient treatment with high-dose vitamin K for 1 week. Upon discharge, he required daily vitamin K and INR monitoring for a further month. The original inpatient team had not identified the specific poison (chlorophacinone). They were unaware that superwarfarins are more potent and longer acting than warfarin, with toxic effects for weeks or even months, and that large doses of vitamin K are often required.

A study exploring drug use and management of patients presenting to an inner city emergency department.

Patients who present to an emergency department (ED) with a problem related to illegal drug use can be difficult to identify and are perceived to generate a significant workload for staff. This study suggests that illicit drug use may be more common than previously reported and also that the impact on the ED is perceived by staff to be disproportionately high compared with the actual numbers of patients presenting with complaints related to illicit drug use. We conclude that the over estimation by staff is directly related to the challenges that staff working within the ED setting believe this group of patients pose.
