The objective of this research was to develop a digital system to archive the complete operative environment along with the assessment tools for analysis of this data, allowing prospective studies of operative performance, intraoperative errors, team performance, and communication. Ability to study this environment will yield new insights, allowing design of systems to avoid preventable errors that contribute to perioperative complications. ⋯ The RATE tool allows prospective analysis of performance measures such as technical judgments, team performance, and communication patterns, offers the opportunity to conduct prospective intraoperative studies of human performance, and allows for postoperative discussion, review, and teaching. This study also suggests that gaps in situational awareness might be an underappreciated source of operative adverse events. Future uses of this system will aid teaching, failure or adverse event analysis, and intervention research.

Clinically positive axillary nodes are widely considered a contraindication to sentinel lymph node (SLN) biopsy in breast cancer, yet no data support this mandate. In fact, data from the era of axillary lymph node dissection (ALND) suggest that clinical examination of the axilla is falsely positive in as many as 30% of cases. Here we report the results of SLN biopsy in a selected group of breast cancer patients with palpable axillary nodes classified as either moderately or highly suspicious for metastasis. ⋯ Clinical axillary examination in breast cancer is subject to false-positive results, and is by itself insufficient justification for axillary lymph node dissection. If other means of preoperative assessment such as palpation- or image-guided fine needle aspiration are negative or indeterminate, then SLN biopsy deserves wider consideration as an alternative to routine axillary lymph node dissection in the clinically node-positive setting.

Trauma is the number one cause of maternal death during pregnancy, but incidence of fetal loss exceeds maternal loss by more than 3 to 1. We hypothesized that we could identify women at risk for injury during pregnancy and focus our prevention efforts. ⋯ Young, African-American, and Hispanic pregnant women are at higher risk for trauma in pregnancy and are most likely to benefit from primary trauma prevention efforts. Those with severe head, abdominal, thoracic, or lower extremity injuries are at high risk for pregnancy loss. Reduction of secondary insults and early recognition of fetal distress may improve outcomes for both the mother and fetus in this high-risk group.
