Review Meta Analysis
Understanding better how emergency doctors work. Analysis of distribution of time and activities of emergency doctors: a systematic review and critical appraisal of time and motion studies.
Optimising the efficiency and productivity of senior doctors is critical to ED function and delivery of safe patient care. Time and motion studies (TMS) can allow quantification of how these doctors spend their working time, identify inefficiencies in the current work processes and provide insights into improving working conditions, and enhancing productivity. Three questions were addressed: (1) How do senior emergency doctors spend their time in the ED? (2) How much of their time is spent on multitasking? (3) What is the number of tasks completed per hour? ⋯ The review revealed that senior doctors spent a large percentage of their time on direct face-to-face contact with patients. The review findings provided a grounded understanding of how senior doctors spent their time in the ED and could be useful in implementing improvements to the emergency care system.

Review Meta Analysis
Outcomes of beta blocker use in cocaine-associated chest pain: a meta-analysis.
Beta blockers (β-blockers) remain a standard therapy in the early treatment of acute coronary syndromes. However, β-blocker therapy in patients with cocaine-associated chest pain (CACP) continues to be an area of debate due to the potential risk of unopposed α-adrenergic stimulation and coronary vasospasm. Therefore, we performed a systematic review and meta-analysis of available studies to compare outcomes of β-blocker versus no β-blocker use among patients with CACP. ⋯ In patients presenting with acute chest pain and underlying cocaine, β-blocker use does not appear to be associated with an increased risk of MI or all-cause mortality.

Review Meta Analysis
Effects of prophylactic anticholinergic medications to decrease extrapyramidal side effects in patients taking acute antiemetic drugs: a systematic review and meta-analysis.
To determine the effectiveness of prophylactic anticholinergic medications in reducing extrapyramidal symptoms in patients taking acute antiemetics with a dopamine D2 receptor antagonist effect. ⋯ Prophylactic diphenhydramine reduces extrapyramidal symptoms in patients receiving bolus antiemetic therapy with a dopamine D2 antagonist effect, but not when it is given as an infusion. Because of significantly greater sedation with diphenhydramine, the most effective strategy is to administer the D2 antagonist antiemetic as a 15 min infusion without prophylaxis.

Review Meta Analysis
Do patients with blunt thoracic aortic injury present to hospital with unstable vital signs? A systematic review and meta-analysis.
Blunt thoracic aortic injury (BTAI) is an uncommon diagnosis, usually developing as a consequence of high-impact acceleration-deceleration mechanisms. Timely diagnosis may enable early resuscitation and reduction of shear forces, essential to prevent worsening of the injury prior to definitive management. Death is commonly due to haemorrhagic shock, but clinical features may be absent until sudden and massive haemorrhage. ⋯ Normal vital signs do not rule out aortic injury. A high degree of clinical suspicion and liberal use of imaging is necessary to prevent missed or delayed diagnoses.

It is hypothesised that a single injection fascia iliaca compartment block (FICB) administered in the pre-operative setting provides better analgesic control for traumatic hip fractures and is not associated with major adverse effects. Systemic analgesics, whilst effective, could lead to cardiovascular, respiratory and cognitive impairment. As a consequence, undertreatment of acute pain remains prevalent in adult patients with hip fractures, with a consistent decline seen in analgesic administration with age. ⋯ Out of 3757 citations, eight RCTs were included in the final quantitative analysis, comprising of 645 participants. Acute pain was significantly reduced in FICB during positioning and movement, standardised mean difference (SMD)=-1.82 (95% CI:-2.26 to -1.38, p<0.00001) but was variable at rest (p=0.20). There was a reduced incidence of analgesia breakthrough (n=57 versus n=73), drowsiness/sedation (n=1 versus n=22), desaturation (n=0 versus n=4) and nausea and vomiting (n=3 versus n=7) in the FICB arm. There were similar numbers of patients across both arms that reported localised bruising (n=3). Only one study was at low risk of bias.emermed;34/12/A891-a/F1F1F1Figure 1emermed;34/12/A891-a/F2F2F2Figure 2 CONCLUSIONS: FICB is superior in controlling acute pre-operative pain in adult patients with traumatic hip fractures. The benefit is more evident during positioning and mobilisation of the limb. FICB has a better safety profile and reduces dependency on systemic analgesia.
