Patients with life-limiting illness presenting to the emergency department.

OBJECTIVE: To examine characteristics, outcomes and flow for patients over the age of 45 years with a life-limiting illness (LLI) presenting to a regional ED. METHODS: Retrospective, observational cohort study of patients with LLI in an Australian regional ED over a 15-day period. Eligible patients were 45 years of age or older who fulfilled criteria for having an LLI. Data included demographics, diagnosis for current presentation, presence of advance care documentation, LLI category, admission and discharge destination from ED, ED and hospital length of stay and outcome for patients admitted to the acute hospital. RESULTS: A total of 152 (12%) patients had an LLI. The LLI group were older, had a significantly longer median length of stay in the ED (5.9 [interquartile range 4.0-8.4] vs 3.9 h [interquartile range 2.5-6.3], P < 0.0001) and were less likely to leave the ED within 4 h (26% vs 51.5%, P < 0.0001). Forty-six percent of patients with an LLI had some form of advanced care documentation. Patients with an LLI were more likely to require hospital admission. In relation to illness trajectory, the frailty/dementia trajectory group had comparatively the longest ED length of stay with less than 10% leaving the ED within 4 h. This group were more likely to be discharged to a residential care facility. CONCLUSION: A significant proportion of patients 45 years or older had an LLI which had implications for their length of ED stay and discharge destination.

Prospective observational study of emergent endotracheal intubation practice in the intensive care unit and emergency department of an Australian regional tertiary hospital.

OBJECTIVE: The present study aimed to describe the characteristics and outcomes of intubation occurring in the ICU and ED of an Australian tertiary teaching hospital. METHODS: This was a prospective observational study of intubation practice across the Geelong Hospital over a 6 month period from 1 August 2012 to 31 January 2013. Data were entered by the intubating team through an online data collection form. RESULTS: There were 119 patients intubated and 134 attempts at intubation in the ED and ICU over a 6 month period. The first-pass success rate was 104/119 (87.4%), and all but a single patient was intubated by the second attempt. Propofol, fentanyl, midazolam and suxamethonium were the most common drugs used in rapid sequence induction. AEs were reported in 44/134 (32.8%) of intubation attempts, with transient hypoxia and hypotension being the most common. A significant adverse outcome, namely aspiration pneumonitis, occurred in one patient. There were no peri-intubation deaths. CONCLUSION: The majority of airways are managed by ICU and ED consultants and trainees, with success rates and AE rates comparable with other published studies.

Use of ultrasound to facilitate accurate femoral nerve block in the emergency department.

OBJECTIVE: To compare the accuracy of ultrasound (US)-assisted femoral nerve blocks (FNB) with the fascial pop (FP) technique, examining the rates of success and complications. METHODS: This is a prospective unblinded pseudo-randomized controlled trial of US-assisted versus FP FNB techniques. The primary outcome measure was nerve block stratified to level of blockade (intact, partial or complete) with FNB assessed by skin sensation. Participants were assessed at 15 and 60 min post nerve block. RESULTS: Sixty-seven patients were enrolled. Thirty-four (50.7% [95% CI 44.7-56.8]) underwent the US-assisted technique whereas thirty-three (49.2% [95% CI 43.4-55.2]) underwent the FP technique. At 15 min, FNB using US was intact, partial or complete for 9 (26.5% [95% CI 22.5-30.4]), 15 (44.1% [95% CI 36.8-51.5]) and 10 (29.4% [95% CI 24.9-33.9]) patients, respectively, compared with 14 (42.4% [95% CI 35.3-49.6]), 17 (51.5% [95% CI 42.7-60.3]) and 2 (6.1% [95% CI 5.6-6.6]) patients, respectively (P = 0.038). There was no difference at 60 min. Complete block at 15 min was achieved in 10/34 patients (29% [95% CI 14.1-44.7]) in the US group and 2/33 patients (6% [95% CI -2.1-14.2]) in the FP group (P = 0.029); no difference was seen at 60 min. No complications were recorded in either group. CONCLUSIONS: A more complete blockade is achieved earlier using the US-assisted technique. The US-assisted technique will become the technique of choice for FNB in this department.

Injury patterns and preventability in prehospital motor vehicle crash fatalities in Victoria.

OBJECTIVE: To examine the pattern of anatomical injury in victims of motor vehicle crashes who die prior to reaching hospital. Cases were identified where death was an unexpected outcome. METHODS: A retrospective review of autopsy case records including police reports, of all persons who died in motor vehicle crashes between 1 January 1998 and 31 December 1999 and underwent full autopsy at the Victorian Institute of Forensic Medicine (VIFM). Those cases where the victim died in the prehospital phase were examined. Abbreviate Injury Scores and Injury Severity Scores were calculated in each case. Bull's probit analysis was used to identify unexpected deaths. RESULTS: There were 352 motor road crash fatalities identified that underwent autopsy at the VIFM in the study period. Two hundred and six of these were prehospital deaths involving motor vehicles, which satisfied specified criteria. 82% (95% CI: 77.7-86.3%) of cases had Abbreviated Injury Scores of 5 (critical) or 6 (incompatible with life). 80.1% (95% CI: 75.7-84.5%) had an Injury Severity Score greater than 40. 36.9% (95% CI: 34.5-39.3%) of cases had the maximum Injury Severity score of 75. 88.8% (95% CI: 85-92.7%) of cases sustained a head injury and 83.9% (95% CI: 79.8-88.2%) a chest injury. Possibly preventable fatality was identified in 30 (14.6% 95% CI: 13.9-15.3%) cases. CONCLUSION: In motor vehicle crash fatalities, most victims who die before reaching hospital do so because of major injury, with the head and chest the commonest regions involved. A large proportion of these injuries could be considered unsurvivable regardless of treatment. Earlier intervention or retrieval of such patients is unlikely to influence outcome in the majority of cases.

Is mediastinal shift on chest X-ray of pneumothorax always an emergency?

OBJECTIVE: To determine the incidence of mediastinal shift on chest X-ray due to pneumothorax. METHODS: A retrospective chart review was undertaken of all patients with pneumothorax presenting to the ED over the period 1 January 1995 to 31 December 1999. The primary outcome was mediastinal shift on initial CXR. The incidence of clinical tension pneumothorax was noted. RESULTS: There were 176 presentations with pneumothorax in the study period. Two cases of clinical tension pneumothorax were identified and treated prior to CXR. Thirty patients with mediastinal shift on initial CXR, none of which clinically merited emergency needle decompression, were all managed with intercostal catheter (ICC) insertion. Overall, 141 of 176 (80.1%) had an ICC inserted as part of their management. Mean pulse rate (91.8 SD 29.5 vs 86.7 SD 23.6, P = 0.02) and respiratory rate (21.9 SD 14.4 vs 15.1 SD 11.5, P = 0.03) were greater in patients with mediastinal shift on CXR. CONCLUSION: True clinical tension pneumothorax is an uncommon condition. Radiological evidence of mediastinal shift is more common. No patient in this latter group deteriorated while awaiting X-ray.
