Recent Actions by the US Food and Drug Administration: Reducing the Risk of Infection from Reprocessed Duodenoscopes.

In addition to technological advancements, engagement and collaboration among the wider community of stakeholders will be beneficial toward reducing the risk of infection from reprocessed duodenoscopes. Such a community can raise awareness of the importance of duodenoscope cleaning, work to improve reprocessing training, identify the most pressing unanswered questions that merit further research, and develop tools that can be used by health care facilities to improve the quality of reprocessing at their sites. The Food and Drug Administration looks forward to working with the community to further reduce the risk of infections from reprocessed duodenoscopes.

Impact of Clinician Personal Protective Equipment on Medical Device Use During Public Health Emergency: A Review.

The aim of this systematic review is to evaluate the impact of personal protective equipment (PPE) on medical device use during public health emergency responses. We conducted a systematic literature search of peer-reviewed journals in PubMed, Web of Science, and EBSCO databases. Twenty-nine of 92 articles published between 1984 and 2015 met the inclusion criteria for the review. Although many medical device use impacts were reported, they predominantly fell into 3 categories: airway management, drug administration, and diagnostics and monitoring. Chemical, biological, radiological, and nuclear (CBRN)-PPE increased completion times for emergency clinical procedures by as much as 130% and first attempt failure rates by 35% (anesthetist) versus 55% (non-anesthetist). Effects of CBRN-PPE use depend on device, CBRN-PPE level, and clinician experience and training. Continuous clinical training of responders in CBRN-PPE and device modifications can improve safety and effectiveness of medical device use during public health emergency response.

Empirical Evaluation of Visual Fatigue from Display Alignment Errors Using Cerebral Hemodynamic Responses.

The purpose of this study was to investigate the effect of stereoscopic display alignment errors on visual fatigue and prefrontal cortical tissue hemodynamic responses. We collected hemodynamic data and perceptual ratings of visual fatigue while participants performed visual display tasks on 8 ft × 6 ft NEC LT silver screen with NEC LT 245 DLP projectors. There was statistical significant difference between subjective measures of visual fatigue before air traffic control task (BATC) and after air traffic control task (ATC 3), (P < 0.05). Statistical significance was observed between left dorsolateral prefrontal cortex oxygenated hemoglobin (l DLPFC-HbO2), left dorsolateral prefrontal cortex deoxygenated hemoglobin (l DLPFC-Hbb), and right dorsolateral prefrontal cortex deoxygenated hemoglobin (r DLPFC-Hbb) on stereoscopic alignment errors (P < 0.05). Thus, cortical tissue oxygenation requirement in the left hemisphere indicates that the effect of visual fatigue is more pronounced in the left dorsolateral prefrontal cortex.
