The administration of propofol target-controlled infusion (TCI) for procedural sedation is standard in a range of hospital settings except for the Emergency Department (ED). Propofol TCI could be an alternative, safer way to provide procedural sedation in the ED compared with other methods of propofol administration. We compare the incidence of adverse events using propofol TCI compared with other methods of propofol administration. ⋯ It was not possible to determine if propofol TCI reduces the incidence of adverse events when compared with other sedating regimens using propofol using a descriptive systematic review of the relevant literature. Further research is required to compare the incidence of adverse events using propofol TCI for procedural sedation with other methods of administration in the ED. Future systematic reviews and meta-analysis comparisons would be aided by the use of standard adverse event reporting tools such as that of the Society of Intravenous Anaesthesia.

A large proportion of patients affected with hypertension go undetected. A systematic review was conducted to assess the performance of a screening strategy in adults using blood pressure measurement at the time of an emergency department consultation. A systematic literature search on Embase, CINHAL and Medline was carried out. ⋯ For diagnostic confirmation, four studies used a blood pressure measurement method based on the reported guidelines. Half of the patients (50.2%) with elevated blood pressure during the emergency department visit had blood pressure corresponding to uncontrolled elevated blood pressure at follow-up measurement. The contribution of emergency department to the screening for hypertension, by recognizing the presence of elevated blood pressure and then making a referral for diagnostic confirmation, could provide an opportunity to detect a large number of people with hypertension.

Meta Analysis
Application of decision rules on diagnosis and prognosis of renal colic: a systematic review and meta-analysis.
Renal colic is a prevalent emergency department presentation resulting from urolithiasis. Clinical decision rules for the diagnosis of urolithiasis were developed to help clinicians with better judgment. In this systematic review, we assessed the performance of prediction rules on urolithiasis diagnosis and prognosis. ⋯ In the high risk score group, prevalence of clinically important alternative diagnosis was 1% (95% confidence interval 0%-2%) and 11% (95% confidence interval 8%-13%) of patients needed intervention. STONE scoring system is useful in estimating the prevalence of urolithiasis but high heterogeneity among the studies makes it unsuitable for application. Other decision tools were poorly studied and cannot be recommended for clinical use.

Medically unexplained symptoms, defined as physical symptoms for which no organic pathology can be found, represent 4% of all emergency department attendances annually. The standard management of these patients involves extensive investigation to rule out organic pathology, followed by simple reassurance. We conducted a literature review to determine if there was any intervention that could improve these patient's symptoms and reduce emergency department attendances. ⋯ Three studies tested cognitive behavioural therapy, with two finding a reduction in emergency department attendance. Overall, evidence regarding interventions for patients with medically unexplained symptoms in the emergency department is limited and of a variable quality, despite comprising 4% of emergency department attendances. Further research is required to determine the best intervention for this challenging patient group.
