The potential that forced-air warming systems may increase the risk of surgical site infections (SSIs) by acting as a vector or causing unwanted airflow disturbances is a concern to health care providers. To investigate this potential, we examined the literature to determine whether forced-air warming devices increase the risk of SSIs in patients undergoing general, vascular, or orthopedic surgical procedures. We examined 192 evidence sources, 15 of which met our inclusion criteria. Most sources we found indirectly addressed the issue of forced-air warming and only three studies followed patients who were warmed intraoperatively with forced-air warming devices to determine whether there was an increased incidence of SSIs. All of the sources we examined contained methodological concerns, and the evidence did not conclusively suggest that the use of forced-air warming systems increases the risk of SSIs. Given the efficacy of these devices in preventing inadvertent perioperative hypothermia, practitioners should continue to use and clean forced-air warming systems according to the manufacturer's instructions until well-conducted, large-scale trials can further examine the issue.

Lateral violence is a problem in nursing despite policies addressing the issue, which suggests that implementation of these policies may be ineffective. We used an evidence-based approach to locate and appraise evidence about effectively implementing lateral violence policies. Our search strategy emphasized preappraised evidence, and we found 12 sources that met our inclusion criteria. Most evidence was from low-level sources, which is not surprising due to the subjective and sensitive nature of this topic. The evidence did not indicate that there is consistent, effective implementation of lateral violence policies. The appraised evidence suggests the importance of collaboratively prepared implementation strategies. Administrator involvement and relationships with staff members and the presence of a commitment to positive behavior change before lateral violence incidents occur are factors that can lead to successful implementation of lateral violence policies.

Sedating patients undergoing advanced endoscopic procedures such as endoscopic retrograde cholangiopancreatography (ERCP) is challenging for the endoscopy team. Considering these challenges and concerns with the use of propofol for deep sedation of older adults and high-risk patients, colleagues of one of the authors (AS) were interested in the identification of techniques for the anesthetic management of subjects undergoing therapeutic ERCP. A search strategy revealed a total of 7 evidence sources. The appraised evidence examined the efficacy and sedation-related effects of anesthesia regimens. Deep sedation with propofol was identified as the most commonly used anesthetic technique for subjects undergoing therapeutic ERCP. The sedation-related unwanted effects of propofol appear to be dose-related and occur more frequently in the high-risk and elderly populations. However, the data were inconclusive in identifying an ideal agent offering superior efficacy with fewer unwanted sedation-related effects. Providers should strongly consider the subject's age, history of coexisting illness, and the pharmacological effects of selected anesthetic agents when choosing an appropriate anesthetic technique. Larger randomized controlled studies are needed to identify risk factors associated with sedation-related complications and to identify alternative options for the anesthetic management of subjects undergoing ERCP.
