Randomized Controlled Trial Multicenter Study
Effect of MRI on treatment results or decision making in patients with lumbosacral radiculopathy referred for epidural steroid injections: a multicenter, randomized controlled trial.
Studies have shown that radiologic imaging does not improve outcomes in most patients with back pain, though guidelines endorse it before epidural steroid injections (ESIs). The objective of this study was to determine whether magnetic resonance imaging (MRI) improves outcomes or affects decision making in patients with lumbosacral radiculopathy referred for ESI. ⋯ Magnetic resonance imaging does not improve outcomes in patients who are clinical candidates for ESI and has only a minor effect on decision making. Trial Registration clinicaltrials.gov Identifier: NCT00826124.

Randomized Controlled Trial
Modest public health impact of nontargeted human immunodeficiency virus screening in 29 emergency departments.
To lower the number of undiagnosed infections and to improve early detection, international health agencies have promoted nontargeted human immunodeficiency virus (HIV) screening in health care settings, including emergency departments (EDs). This strategy remains controversial and has yet to be tested on a large scale. We assessed the public health impact of nontargeted HIV-rapid test (RT) screening among ED patients in the metropolitan area of Paris (11.7 million inhabitants), where half of France's new HIV cases are diagnosed annually. ⋯ Nontargeted HIV testing in EDs was feasible but identified only a few new HIV diagnoses, often at late stages, and, unexpectedly, most patients belonged to a high-risk group. Our findings do not support the implementation of nontargeted screening of the general population in EDs.
