Acute Kidney Injury After Computed Tomography: A Meta-analysis.
Computed tomography (CT) is an important imaging modality used in the diagnosis of a variety of disorders. Imaging quality may be improved if intravenous contrast is added, but there is a concern for potential renal injury. Our goal is to perform a meta-analysis to compare the risk of acute kidney injury, need for renal replacement, and total mortality after contrast-enhanced CT versus noncontrast CT. ⋯ We found no significant differences in our principal study outcomes between patients receiving contrast-enhanced CT versus those receiving noncontrast CT. Given similar frequencies of acute kidney injury in patients receiving noncontrast CT, other patient- and illness-level factors, rather than the use of contrast material, likely contribute to the development of acute kidney injury.

We adopt a comparative framework to measure the extent to which variance in the efficacy of alcohol brief interventions to reduce hazardous and harmful drinking at less than or equal to 5-, 6-, and 12-month follow-up in emergency department settings can be determined by differences between study populations (targeted injury and noninjury specific). ⋯ Meta-analysis identified noninjury-specific studies as associated with better response to brief intervention than targeted injury studies. However, the inclusion of injured patients with noninjured ones in the experimental and control groups of noninjury-specific studies limited the interpretation of this finding.

Nonphysician Out-of-Hospital Rapid Sequence Intubation Success and Adverse Events: A Systematic Review and Meta-Analysis.
Rapid sequence intubation performed by nonphysicians such as paramedics or nurses has become increasingly common in many countries; however, concerns have been stated in regard to the safe use and appropriateness of rapid sequence intubation when performed by these health care providers. The aim of our study is to compare rapid sequence intubation success and adverse events between nonphysician and physician in the out-of-hospital setting. ⋯ This analysis shows that physicians have a higher rapid sequence intubation first-pass and overall success, as well as mostly lower rates of adverse events for rapid sequence intubation in the out-of-hospital setting. Nevertheless, for all success and adverse events no firm conclusion for a difference could be drawn because of lack of precision of meta-analytic estimates or selective reporting. First-pass success could be an area in which to focus quality improvement strategies for nonphysicians.
