ReviewReview article: Best practice management of low back pain in the emergency department (part 1 of the musculoskeletal injuries rapid review series).
Low back pain (LBP) is a common presentation to the ED, and a frequent cause of disability globally. The ED management is often associated with high rates of imaging, misuse and overuse of pharmacology and subsequent financial implications. Given this, improved quality of care for patients with LBP in ED is essential. ⋯ The search revealed 1538 articles, of which 38 were included in the review (n = 8 primary articles, n = 13 systematic reviews and n = 17 guidelines). This rapid review provides clinicians managing LBP in the ED a summary of the best available evidence to risk stratify and enhance the quality of care, optimising patient outcomes. Consistent evidence was found to support the use of 'red flags' to screen for serious pathologies, diagnostic tests being reserved for use only in the presence of red flags, the judicious prescribing of opioids, identification of psychosocial risk factors as predictors of poorer outcome and promotion of early return to work and function.

ReviewReview article: Sepsis in the emergency department - Part 2: Investigations and monitoring.
Sepsis is characterised by organ dysfunction resulting from infection, with no reliable single objective test and current diagnosis based on clinical features and results of investigations. In the ED, investigations may be conducted to diagnose infection as the cause of the presenting illness, identify the source, distinguish sepsis from uncomplicated infection (i.e. without organ dysfunction) and/ or risk stratification. Appropriate sample collection for microbiological testing remains key for subsequent confirmation of diagnosis and rationalisation of antimicrobials. ⋯ New technologies for screening multiple genes and proteins are identifying unique network 'signatures' of clinical interest. Other future directions include rapid detection of bacterial DNA in blood, genes for antibiotic resistance and EMR-based computational biomarkers that collate multiple information sources. Reliable, cost-effective tests, validated in the ED to promptly and accurately identify sepsis, and to guide initial antibiotic choices, are important goals of current research efforts.
